However, the biological processes driving tolerance to delta-9-tetrahydrocannabinol (Δ9-THC), the main psychoactive component of cannabis, remain unclear. Thus, this study aimed to investigate the mechanisms and time course of tolerance development and loss to Δ9-THC in mice. Male ICR mice (7 weeks old) were administered Δ9-THC once daily for 3 days and then divided into three groups according to the washout period (3-, 10-, and 17-day washout groups). After each washout, changes in body temperature and locomotor activity were measured following re-exposure to Δ9-THC. Furthermore, the mRNA expression levels of CB1 and CB2 receptors in the brain were evaluated using real-time PCR. On day 1, significant hypothermia and reduced spontaneous locomotor activity were observed in the Δ9-THC-treated mice compared with the vehicle-treated mice. Tolerance to the hypothermic and locomotor-suppressing effects of Δ9-THC developed on days 2 and 3, respectively, and dissipated after 3 and 11 days of washout, respectively. These differences in the rates of tolerance development and recovery may reflect distinct underlying mechanisms. No significant changes in receptor mRNA expression were observed. These findings highlight the complexity of Δ9-THC tolerance and its potential implications for long-term cannabis use. en-copyright= kn-copyright= en-aut-name=EguchiYukiomi en-aut-sei=Eguchi en-aut-mei=Yukiomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieKeiichi en-aut-sei=Irie en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaYuta en-aut-sei=Yamashita en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EguchiMiyu en-aut-sei=Eguchi en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoTakafumi en-aut-sei=Nakano en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MishimaKenichi en-aut-sei=Mishima en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=2 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=4 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=5 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=6 en-affil=Department of Oncology and Infectious Disease Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= en-keyword=delta-9-tetrahydrocannabinol kn-keyword=delta-9-tetrahydrocannabinol en-keyword=cannabis kn-keyword=cannabis en-keyword=tolerance kn-keyword=tolerance en-keyword=locomotor kn-keyword=locomotor en-keyword=hypothermic kn-keyword=hypothermic END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=421 end-page=429 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Thoron Inhalation and Cyclosporin A Treatment on Dextran Sulfate Sodium-Induced Oxidative Damage in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects. en-copyright= kn-copyright= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=thoron kn-keyword=thoron en-keyword=DSS kn-keyword=DSS en-keyword=antioxidant activity kn-keyword=antioxidant activity en-keyword=CsA kn-keyword=CsA en-keyword=colon kn-keyword=colon END start-ver=1.4 cd-journal=joma no-vol=163 cd-vols= no-issue=22 article-no= start-page=224312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fourier-transform infrared spectroscopy of hydrogen fluoride dimers in solid parahydrogen en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigate the Fourier-transform infrared spectra of hydrogen fluoride dimers in solid parahydrogen, the detailed analysis of which has remained unexplored. We propose a plausible analysis based on concentration dependence, light polarization, annealing, and time evolution. The absorption lines exhibited multiple peaks, with intensity ratios significantly altered by annealing and by time evolution at a constant temperature. The spectral patterns and isotopic effects suggest that the dimers do not rotate freely in solid parahydrogen, while multiple peaks arise from different stable structures, including single and double substitution sites. Unlike in the gas phase and helium droplets, no tunneling splitting was observed. The broad ν1 band suggests that some dimer structures may exhibit axial rotation. Spectral changes due to annealing likely result from site conversion, while observed IR-induced changes indicate preferential dissociation of dimers in double substitution sites. These findings still remain tentative, necessitating further experimental and theoretical studies. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OoeHiroki en-aut-sei=Ooe en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Rikkyo University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=13 article-no= start-page=e202419624 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Conduction Band and Defect Engineering for the Prominent Visible‐Light Responsive Photocatalysts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling trap depth is crucial to improve photocatalytic activity, but designing such crystal structures has been challenging. In this study, we discovered that in 2D materials like BiOCl and Bi4NbO8Cl, composed of interleaved [Bi2O2]2+ and Cl- slabs, the trap depth can be controlled by manipulating the slab stacking structure. In BiOCl, oxygen vacancies (VO) create deep electron traps, while chlorine vacancies (VCl) produce shallow traps. The depth is determined by the coordination around anion vacancies: VO forms strong σ bonds with Bi-6p dangling bonds below the conduction band minimum (CBM), while those around Cl are parallel, forming weak π-bonding. The strong re-hybridization makes the trap depth deeper. In Bi4NbO8Cl, VCl also creates shallow traps, but VO does not produce deep traps although Bi-6p orbitals are also forming strong σ bonding. This difference is attributed to the difference of the energy level of CBM. In both cases, the CBM consists of Bi-6p orbitals extending into the Cl layers. However, these orbitals are isolated in BiOCl, but those in Bi4NbO8Cl are bonded with each other between neighboring [Bi2O2]2+ layers. This unique bonding-based CBM prevents the formation of deep electron traps, and significantly enhances H2 evolution activity by prolonging the lifetime of highly reactive free electrons. en-copyright= kn-copyright= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaTakafumi en-aut-sei=Ogawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaKanta en-aut-sei=Ogawa en-aut-mei=Kanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaMakoto en-aut-sei=Ogawa en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoDaichi en-aut-sei=Kato en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhongChengchao en-aut-sei=Zhong en-aut-mei=Chengchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuwabaraAkihide en-aut-sei=Kuwabara en-aut-mei=Akihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeRyu en-aut-sei=Abe en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KageyamaHiroshi en-aut-sei=Kageyama en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=4 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=5 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=6 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=7 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Nanostructures Research Laboratory, Japan Fine Ceramics Center kn-affil= affil-num=9 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= affil-num=10 en-affil=Department of Energy and Hydrocarbon Chemistry Graduate School of Engineering, Kyoto University kn-affil= en-keyword=photocatalysis kn-keyword=photocatalysis en-keyword=defects kn-keyword=defects en-keyword=charge trapping kn-keyword=charge trapping en-keyword=recombination kn-keyword=recombination en-keyword=time-resolved spectroscopy kn-keyword=time-resolved spectroscopy END start-ver=1.4 cd-journal=joma no-vol=163 cd-vols= no-issue=19 article-no= start-page=191101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interplay of coil–globule transitions and aggregation in homopolymer aqueous solutions: Simulation and topological insights en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigate the structural and topological properties of hydrophobic homopolymer chains in aqueous solutions using molecular dynamics simulations and circuit topology (CT) analysis. By combining geometric observables, such as the radius of gyration and the degree of aggregation, with CT data, we capture the relationship between coil–globule and aggregation transitions, resolving the system’s structural changes with temperature. Our results reveal a temperature-driven collective transition from isolated coiled chains to globular aggregates. At a characteristic transition temperature Tc, each chain in multichain systems undergoes a rapid coil–globule collapse, coinciding with aggregation, in contrast to the gradual collapse observed in single-chain systems at infinite dilution. This collective transition is reflected in geometric descriptors and a reorganization of CT motifs, shifting from intrachain-dominated motifs at low temperatures to a diverse ensemble of multichain motifs at higher temperatures. CT motif enumeration provides contact statistics while offering a topologically detailed view of polymer organization. These findings highlight CT’s utility as a structural descriptor for polymer systems and suggest applications for biopolymer aggregation and folding. en-copyright= kn-copyright= en-aut-name=KomatsuJunichi en-aut-sei=Komatsu en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BerxJonas en-aut-sei=Berx en-aut-mei=Jonas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Niels Bohr International Academy, Niels Bohr Institute, University of Copenhagen kn-affil= END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=366 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of thienoacenes by electrochemical double C–S cyclization using a halogen mediator en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thienoacenes are significant compounds as organic materials. One of the most efficient ways to synthesize thienoacenes is to form multiple C–S bonds in a single step. Because unprotected S–H bonds are easily oxidized to S–S bonds, S-Me protected substrates are commonly used for the purpose. However, their reactivity is insufficient, and one-step construction of multiple C–S bonds is still challenging. We herein report the electrochemical synthesis of thienoacenes from S-methoxymethyl (MOM)-protected diarylacetylenes. In the presence of Bu4NBr as a halogen mediator, electrochemical double C–S cyclization of diarylacetylenes bearing two MOM groups proceeded to afford [1]benzothieno[3,2-b][1]benzothiophene (BTBT) derivatives. While S-Me or S-p-methoxybenzyl (PMB)-protected diarylacetylenes did not afford BTBT, BTBT was selectively obtained when a substrate protected with S-MOM groups was used. The S-MOM protection strategy is also effective for the electrochemical synthesis of a more π-expanded thienoacene such as dibenzo[d,d′]thieno[3,2-b,4,5-b′]dithiophene (DBTDT). en-copyright= kn-copyright= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaharaTakuya en-aut-sei=Nagahara en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatauraNozomi en-aut-sei=Kataura en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkamuraYuka en-aut-sei=Okamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonezawaToki en-aut-sei=Yonezawa en-aut-mei=Toki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TachibanaYuri en-aut-sei=Tachibana en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SouliéNolan en-aut-sei=Soulié en-aut-mei=Nolan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShigemoriKeisuke en-aut-sei=Shigemori en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MandaiHiroki en-aut-sei=Mandai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SugaSeiji en-aut-sei=Suga en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Science and Engineering, Sorbonne Université kn-affil= affil-num=8 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Faculty of Pharmacy, Gifu University of Medical Science kn-affil= affil-num=11 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=5 article-no= start-page=257 end-page=267 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New Catalytic Residues and Catalytic Mechanism of the RNase T1 Family en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ribonuclease T1 family, including RNase Po1 secreted by Pleurotus ostreatus, exhibits antitumor activity. Here, we resolved the Po1/guanosine-3′-monophosphate complex (3′GMP) structure at 1.75 Å. Structure comparison and fragment molecular orbital (FMO) calculation between the apo form and the Po1/3′GMP complex identified Phe38, Phe40, and Glu42 as the key binding residues. Two types of the RNase/3′GMP complex in RNasePo1 and RNase T1 were homologous to Po1, and FMO calculations elucidated that the biprotonated histidine on the β3 sheet (His36) on the β3 sheet and deprotonated Glu54 on the β4 sheet were advantageous to RNase activity. Moreover, tyrosine (Tyr34) on the β3 sheet was elucidated as a crucial catalytic residues. Mutation of Tyr34 with phenylalanine decreased RNase activity and diminished antitumor efficacy compared to that in the wild type. This suggests the importance of RNase activity in antitumor mechanisms. en-copyright= kn-copyright= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiMamoru en-aut-sei=Suzuki en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraYumiko en-aut-sei=Hara en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsutaniTakuya en-aut-sei=Katsutani en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotoyoshiNaomi en-aut-sei=Motoyoshi en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItagakiTadashi en-aut-sei=Itagaki en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyakawaShuhei en-aut-sei=Miyakawa en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoKuniaki en-aut-sei=Okamoto en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FukuzawaKaori en-aut-sei=Fukuzawa en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KobayashiHiroko en-aut-sei=Kobayashi en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Institute for Protein Research, Osaka University kn-affil= affil-num=3 en-affil=Institute for Protein Research, Osaka University kn-affil= affil-num=4 en-affil=Institute for Protein Research, Osaka University kn-affil= affil-num=5 en-affil=School of Pharmacy, Nihon University kn-affil= affil-num=6 en-affil=School of Pharmacy, Nihon University kn-affil= affil-num=7 en-affil=Graduate School of Pharmaceutical Sciences, Osaka University kn-affil= affil-num=8 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Pharmaceutical Sciences, Osaka University kn-affil= affil-num=10 en-affil=School of Pharmacy, Nihon University kn-affil= en-keyword=RNase kn-keyword=RNase en-keyword=crystal structure kn-keyword=crystal structure en-keyword=fragment molecular orbital method kn-keyword=fragment molecular orbital method en-keyword=interfragment interaction energy kn-keyword=interfragment interaction energy en-keyword=antitumor activity kn-keyword=antitumor activity en-keyword=RNase activity kn-keyword=RNase activity END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=189 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240827 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Post-spinel-type AB2O4 high-pressure phases in geochemistry and materials science en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-spinel-type AB2O4 compounds are stable at higher pressures than spinel phases.

Prospects are discussed for future searches for post-spinel-type phases by applying advanced large-volume high-pressure technology. en-copyright= kn-copyright= en-aut-name=AkaogiMasaki en-aut-sei=Akaogi en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauraKazunari en-aut-sei=Yamaura en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Gakushuin University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Research Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=131 cd-vols= no-issue=9 article-no= start-page=744 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optical and chemical properties of silver tree-like structure treated with gold galvanic substitution en-subtitle= kn-subtitle= en-abstract= kn-abstract=Galvanic gold substitution was executed in the presence of trisodium citrate on silver tree-like structures. No discernible difference in geometry was observed between the pre- and post-gold substitution phases, which benefited from the presence of citrate ions. The extent of gold substitution was regulated by the amount of gold ion solution added. After the gold substitution, an increase in extinction was observed in the ultraviolet region, indicating that gold was deposited at the surface. Raman scattering of para-toluenethiol was measured on the gold/silver tree-like structures at 488 nm excitations, where a decrease in the Raman peak intensity was observed as the quantity of gold ion solution increased. The results indicated that the optical property of silver was lost due to the increase of the amount of gold deposition. Concurrently, an investigation was conducted into the chemical resistance of the gold/silver tree-like structures, which was evaluated by measuring the resistivity inverse-proportional to the amount of silver ions dissolved by the diluted nitric acid. As the amount of gold ion solution added increased, the resistivity increased and became constant. The result implied that the surface chemical property had undergone a complete transformation into gold. en-copyright= kn-copyright= en-aut-name=HondaKazushi en-aut-sei=Honda en-aut-mei=Kazushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Gold/silver tree-like structures kn-keyword=Gold/silver tree-like structures en-keyword=Galvanic substitution kn-keyword=Galvanic substitution en-keyword=SERS kn-keyword=SERS en-keyword=Raman mapping kn-keyword=Raman mapping END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250810 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of the relationship between solid‐state photoluminescence and crystal structures in 2,6‐substituted naphthalene derivatives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Polycyclic aromatic hydrocarbons (PAHs) are known to exhibit fluorescence in solution, but generally do not emit in the solid state, with the notable exception of anthracene. We previously reported that PAHs containing multiple chromophores show solid-state emission, and we have investigated the relationship between their crystal structures and photoluminescence properties. In particular, PAHs with herringbone-type crystal packing, such as 2,6-diphenylnaphthalene (DPhNp), which has a slender and elongated molecular structure, exhibits red-shifted solid-state fluorescence spectra relative to their solution-phase counterparts. In this study, we synthesized 2,6-naphthalene derivatives bearing phenyl and/or pyridyl substituents (PhPyNp and DPyNp) and observed distinct, red-shifted emission in the solid state compared with that in solution. Crystallographic analysis revealed that both PhPyNp and DPyNp adopt herringbone packing motifs. These findings support our hypothesis that the spectral characteristics of PAH emission are closely linked to crystal packing arrangements, providing a useful strategy for screening PAH candidates for applications in organic semiconducting materials. en-copyright= kn-copyright= en-aut-name=YamajiMinoru en-aut-sei=Yamaji en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshikawaIsao en-aut-sei=Yoshikawa en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MutaiToshiki en-aut-sei=Mutai en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoujouHirohiko en-aut-sei=Houjou en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoKenta en-aut-sei=Goto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiKengo en-aut-sei=Suzuki en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Division of Materials and Environment, Graduate School of Science and Engineering, Gunma University kn-affil= affil-num=2 en-affil=Department of Materials and Environmental Science, Institute of Industrial Science, The University of Tokyo kn-affil= affil-num=3 en-affil=Technology Transfer Service Corporation kn-affil= affil-num=4 en-affil=Department of Materials and Environmental Science, Institute of Industrial Science, The University of Tokyo kn-affil= affil-num=5 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=6 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=7 en-affil=Hamamatsu Photonics K.K kn-affil= affil-num=8 en-affil=Department of Chemistry, Faculty of Environment, Life, Natural Sciences and Technology, Okayama University kn-affil= en-keyword=herringbone kn-keyword=herringbone en-keyword=polycyclic aromatic hydrocarbon kn-keyword=polycyclic aromatic hydrocarbon en-keyword=solid-state emission kn-keyword=solid-state emission END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202510319 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels–Alder Reaction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fleeting molecules possessing strained multiple bonds are important components in organic synthesis due to their ability to undergo various chemical reactions driven by the release of strain energy. Although the use of strained π-bonds as 2π components, represented by dienophiles in Diels–Alder reactions, has been well studied, “the strained diene (4π component) approach” for molecular construction remains underexplored. Herein, we report the design of a vinyl cyclic allene (1-vinyl-1,2-cyclohexadiene) as a highly reactive strained diene and the development of its Diels–Alder reactions. Experimental and computational studies of vinyl cyclic allenes revealed that this diene system undergoes cycloaddition with dienophiles regio- and stereoselectively under mild reaction conditions. These studies also provide insight into the reactivity and selectivity of the system. The strained diene approach enables the convergent construction of polycyclic molecules through bond disconnections distinct from conventional retrosynthetic analysis, thus offering an efficient strategy for the assembly of functional molecules. en-copyright= kn-copyright= en-aut-name=MizoguchiHaruki en-aut-sei=Mizoguchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataTakumi en-aut-sei=Obata en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiTaiki en-aut-sei=Hirai en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuManaka en-aut-sei=Komatsu en-aut-mei=Manaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakakuraAkira en-aut-sei=Sakakura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Activation strain model kn-keyword=Activation strain model en-keyword=Carbocycles kn-keyword=Carbocycles en-keyword=Diels–Alder reaction kn-keyword=Diels–Alder reaction en-keyword=Strained diene kn-keyword=Strained diene en-keyword=Vinylated cyclic allene kn-keyword=Vinylated cyclic allene END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=157 end-page=166 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Continuous Stimulation with Glycolaldehyde-derived Advanced Glycation End Product Reduces Aggrecan and COL2A1 Production via RAGE in Human OUMS-27 Chondrosarcoma Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chondrocytes are responsible for the production of extracellular matrix (ECM) components such as collagen type II alpha-1 (COL2A1) and aggrecan, which are loosely distributed in articular cartilage. Chondrocyte dysfunction has been implicated in the pathogenesis of rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). With age, advanced glycation end products (AGEs) accumulate in all tissues and body fluids, including cartilage and synovial fluid, causing and accelerating pathological changes associated with chronic diseases such as OA. Glycolaldehyde-derived AGE (AGE3), which is toxic to a variety of cell types, have a stronger effect on cartilage compared with other AGEs. To understand the long-term effects of AGE3 on cartilage, we stimulated a human chondrosarcoma cell line (OUMS-27), which exhibits a chondrocytic phenotype, with 10 μg/ml AGE3 for 4 weeks. As a result, the expressions of COL2A1 and aggrecan were significantly downregulated in the OUMS-27 cells without inducing cell death, but the expressions of proteases that play an important role in cartilage destruction were not affected. Inhibition of the receptor for advanced glycation end products (RAGE) suppressed the AGE3-induced reduction in cartilage component production, suggesting the involvement of RAGE in the action of AGE3. en-copyright= kn-copyright= en-aut-name=HatipogluOmer Faruk en-aut-sei=Hatipoglu en-aut-mei=Omer Faruk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishinakaTakashi en-aut-sei=Nishinaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaykasliKursat Oguz en-aut-sei=Yaykasli en-aut-mei=Kursat Oguz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriShuji en-aut-sei=Mori en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeMasahiro en-aut-sei=Watanabe en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyomuraTakao en-aut-sei=Toyomura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiHideo en-aut-sei=Takahashi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=2 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=3 en-affil=Department of Internal Medicine 3-Rheumatology and Immunology, Friedrich-Alexander-University Erlangen-Nürnberg (FAU) and Universitätsklinikum Erlangen kn-affil= affil-num=4 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=7 en-affil=Department of Translational Research & Dug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=10 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= en-keyword=advanced glycation end product kn-keyword=advanced glycation end product en-keyword=aging kn-keyword=aging en-keyword=cartilage kn-keyword=cartilage en-keyword=collagen kn-keyword=collagen en-keyword=aggrecan kn-keyword=aggrecan END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=670 end-page=679 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photochemically assisted synthesis of phenacenes fluorinated at the terminal benzene rings and their electronic spectra en-subtitle= kn-subtitle= en-abstract= kn-abstract=[n]Phenacenes ([n] = 5-7), octafluorinated at the terminal benzene rings (F8-phenacenes: F8PIC, F8FUL, and F87PHEN), were photochemically synthesized, and their electronic spectra were investigated to reveal the effects of the fluorination on the electronic features of phenacene molecules. F8-Phenacenes were conveniently synthesized by the Mallory photoreaction of the corresponding fluorinated diarylethenes as the key step. Upon fluorination on the phenacene cores, the absorption and fluorescence bands of the F8-phenacenes in CHCl3 systematically red-shifted by ca. 3-5 nm compared to those of the corresponding parent phenacenes. The vibrational progressions of the absorption and fluorescence bands were little affected by the fluorination in the solution phase. In the solid state, the absorption band of F8-phenacenes appeared in the similar wavelength region for the corresponding parent phenacenes whereas their fluorescence bands markedly red-shifted and broadened. These observations suggest that the intermolecular interactions of excited-state F8-phenacene molecules are significantly different from those of the corresponding parent molecules, most likely due to different crystalline packing motifs. en-copyright= kn-copyright= en-aut-name=IshiiYuuki en-aut-sei=Ishii en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiMinoru en-aut-sei=Yamaji en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoKenta en-aut-sei=Goto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Molecular Science, Graduate School of Science and Engineering, Gunma University kn-affil= affil-num=3 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=4 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=fluorescence kn-keyword=fluorescence en-keyword=fluorinated aromatics kn-keyword=fluorinated aromatics en-keyword=phenacene kn-keyword=phenacene en-keyword=photoreaction kn-keyword=photoreaction END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202403213 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antifouling Activity of Xylemin, Its Structural Analogs, and Related Polyamines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biofouling, which is the accumulation of organisms on undersea structures, poses significant global, social, and economic issues. Although organotin compounds were effective antifoulants since the 1960s, they were banned in 2008 due to their toxicity to marine life. Although tin-free alternatives have been developed, they also raise environmental concerns. This underscores the need for effective, nontoxic antifouling agents. We previously synthesized N-(4-aminobutyl)propylamine (xylemin) and its structural analogs. In this study, we assayed the antifouling activity and toxicity of xylemin, its structural analogs, and related polyamines toward cypris larvae of the barnacle Amphibalanus amphitrite. Xylemin and its Boc-protected analog exhibited antifouling activities with 50% effective concentrations (EC50) of 4.25 and 6.11 µg/mL, respectively. Four xylemin analogs did not show a settlement-inhibitory effect at a concentration of 50 µg/mL. Putrescine, spermidine, spermine, and thermospermine, which are xylemin-related polyamines, did not display antifoulant effects (EC50 > 50 µg/mL). All evaluated compounds were nontoxic at a concentration of 50 µg/mL. These findings indicate that the size and structure of the N-alkyl group are essential for the antifouling activity of xylemin. Therefore, xylemin and its analogs hold promise as nontoxic, eco-friendly antifouling agents, offering a sustainable solution to biofouling in marine environments. en-copyright= kn-copyright= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YorisueTakefumi en-aut-sei=Yorisue en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Natural and Environmental Sciences, University of Hyogo kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Amines kn-keyword=Amines en-keyword=Antifouling activity kn-keyword=Antifouling activity en-keyword=Barnacle kn-keyword=Barnacle en-keyword=Structure–activity relationships kn-keyword=Structure–activity relationships en-keyword=Xylemin kn-keyword=Xylemin END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=8 article-no= start-page=e202418546 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=B,N‐Embedded Helical Nanographenes Showing an Ion‐Triggered Chiroptical Switching Function en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intramolecular oxidative aromatic coupling of 3,6-bis(m-terphenyl-2’-yl)carbazole provided a bis(m-terphenyl)-fused carbazole, while that of 3,6-bis(m-terphenyl-2’-yl)-1,8-diphenylcarbazole afforded a bis(quaterphenyl)-fused carbazole. Borylation of the latter furnished a B,N-embedded helical nanographene binding a fluoride anion via a structural change from the three-coordinate boron to the four-coordinate boron. The anionic charge derived from the fluoride anion is stabilized over the expanded π-framework, which leads to the high binding constant (Ka) of 1×105 M−1. The four-coordinate boron species was converted back to the parent three-coordinate boron species with Ag+, and the chiroptical switch between the three-coordinate boron and four-coordinate boron species has been achieved via the ion recognition with the change in the color and glum values. en-copyright= kn-copyright= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MichishitaSayaka en-aut-sei=Michishita en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasutomoIssa en-aut-sei=Yasutomo en-aut-mei=Issa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Boron kn-keyword=Boron en-keyword=Chirality kn-keyword=Chirality en-keyword=Circularly polarized luminescence kn-keyword=Circularly polarized luminescence en-keyword=Helical nanographenes kn-keyword=Helical nanographenes en-keyword=Ion sensing kn-keyword=Ion sensing END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=51 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoinitiators Induce Histamine Production in Human Mast Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoinitiators are used in the manufacture of many daily products, and may produce harmful effects due to their cytotoxicity. They have also been detected in human serum. Here, we investigated the histamine-producing effects in HMC-1 cells and the inflammatory cytokine release effects in RAW264 cells for four photoinitiators: 1-hydroxycyclohexyl phenyl ketone; 2-isopropylthioxanthone; methyl 2-benzoylbenzoate; and 2-methyl-4´-(methylthio)-2-morpholinopropiophenone. All four promoted histamine production in HMC-1 cells; however, they did not significantly affect the release of inflammatory cytokines in RAW264 cells. These findings suggest that these four photoinitiators induce inflammatory cytokine-independent histamine production, potentially contributing to histamine-mediated chronic inflammation in vitro. en-copyright= kn-copyright= en-aut-name=MiuraTaro en-aut-sei=Miura en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiYoichi en-aut-sei=Kawasaki en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Laboratory of Clinical Pharmacology and Therapeutics, Kagawa School of Pharmaceutical Sciences, Tokushima Bunri University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photoinitiator kn-keyword=photoinitiator en-keyword=ink kn-keyword=ink en-keyword=injection kn-keyword=injection en-keyword=histamine kn-keyword=histamine en-keyword=inflammation kn-keyword=inflammation END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=14 article-no= start-page=e202404400 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Graphene Oxide as a Self‐Carbocatalyst to Facilitate the Ring‐Opening Polymerization of Glycidol for Efficient Polyglycerol Grafting en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grafting carbon-based nanomaterials (CNMs) with polyglycerol (PG) improves their application potentials in biomedicine and electronics.

We reveal that carboxyl groups spontaneously react with the epoxide ring with no need of catalyst, while GO catalyzes the reactions of hydroxyl groups with the epoxide of glycidol. In addition, the hydroxyl group of glycidol can open the epoxide in the basal plane of GO. The subsequent polymerization of PG is supposed to propagate at the primary and/or the secondary hydroxyl groups, generating a ramified PG macromolecule with random branch-on-branch topology. In addition, ketones, benzyl esters and aromatic ethers are found not to react with glycidol even in the presence of GO, while the aldehydes are easily oxidized into carboxyl groups under ambient condition, behaving then as the carboxyl groups. Our findings pose the foundation for understanding the polymerization mechanism of PG on CNMs. en-copyright= kn-copyright= en-aut-name=ZouYajuan en-aut-sei=Zou en-aut-mei=Yajuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhkuraKentaro en-aut-sei=Ohkura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Ortiz‐AnayaIsrael en-aut-sei=Ortiz‐Anaya en-aut-mei=Israel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Carbon nanomaterials kn-keyword=Carbon nanomaterials en-keyword=Epoxide ring-opening kn-keyword=Epoxide ring-opening en-keyword=Catalysis kn-keyword=Catalysis en-keyword=Polyglycerol functionalization kn-keyword=Polyglycerol functionalization END start-ver=1.4 cd-journal=joma no-vol=159 cd-vols= no-issue=19 article-no= start-page=194504 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficiency and energy balance for substitution of CH4 in clathrate hydrates with CO2 under multiple-phase coexisting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many experimental and theoretical studies on CH4–CO2 hydrates have been performed aiming at the extraction of CH4 as a relatively clean energy resource and concurrent sequestration of CO2. However, vague or insufficient characterization of the environmental conditions prevents us from a comprehensive understanding of even equilibrium properties of CH4–CO2 hydrates for this substitution. We propose possible reaction schemes for the substitution, paying special attention to the coexisting phases, the aqueous and/or the fluid, where CO2 is supplied from and CH4 is transferred to. We address the two schemes for the substitution operating in three-phase and two-phase coexistence. Advantages and efficiencies of extracting CH4 in the individual scheme are estimated from the chemical potentials of all the components in all the phases involved in the substitution on the basis of a statistical mechanical theory developed recently. It is found that although substitution is feasible in the three-phase coexistence, its working window in temperature–pressure space is much narrower compared to the two-phase coexistence condition. Despite that the substitution normally generates only a small amount of heat, a large endothermic substitution is suggested in the medium pressure range, caused by the vaporization of liquid CO2 due to mixing with a small amount of the released CH4. This study provides the first theoretical framework toward the practical use of hydrates replacing CH4 with CO2 and serves as a basis for quantitative planning. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=161 cd-vols= no-issue=21 article-no= start-page=214501 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The nature of the hydrophobic interaction varies as the solute size increases from methane’s to C60’s en-subtitle= kn-subtitle= en-abstract= kn-abstract=The hydrophobic interaction, often combined with the hydrophilic or ionic interactions, makes the behavior of aqueous solutions very rich and plays an important role in biological systems. Theoretical and computer simulation studies have shown that the water-mediated force depends strongly on the size and other chemical properties of the solute, but how it changes with these factors remains unclear. We report here a computer simulation study that illustrates how the hydrophobic pair interaction and the entropic and enthalpic terms change with the solute size when the solute–solvent weak attractive interaction is unchanged with the solute size. The nature of the hydrophobic interaction changes qualitatively as the solute size increases from that of methane to that of fullerene. The potential of mean force between small solutes has several well-defined extrema, including the third minimum, whereas the potential of mean force between large solutes has the deep contact minimum and the large free-energy barrier between the contact and the water-bilayer separated configurations. The difference in the potential of mean force is related to the differences in the water density, energy, and hydrogen bond number distributions in the vicinity of the pairs of hydrophobic solutes. en-copyright= kn-copyright= en-aut-name=NaitoHidefumi en-aut-sei=Naito en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=e202400552 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potassium tert-Butoxide-Mediated Ring-Opening of Indolines: Concise Synthesis of 2-Vinylanilines en-subtitle= kn-subtitle= en-abstract= kn-abstract=A concise and metal-free procedure has been developed for the synthesis of 2-vinylanilines.

Upon photoirradiation, the mixed-dimension MoSe2/C60 (2D/0D) heterojunction generates a charge-separated state (MoSe2⋅+/C60⋅−) through electron extraction from the exciton in MoSe2 to C60. This process is followed by the hydrogen evolution reaction (HER) from water in the presence of a sacrificial donor (1-benzyl-1,4-dihydronicotinamide) and co-catalyst (Pt-PVP). The apparent quantum yields of the HER were estimated to be 0.06 % and 0.27 % upon photoexcitation at the A- and B-exciton absorption peaks (λmax=800 and 700 nm), respectively. en-copyright= kn-copyright= en-aut-name=TajimaTomoyuki en-aut-sei=Tajima en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraTomoki en-aut-sei=Matsuura en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EfendiArif en-aut-sei=Efendi en-aut-mei=Arif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YukimotoMariko en-aut-sei=Yukimoto en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaguchiYutaka en-aut-sei=Takaguchi en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= affil-num=4 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= affil-num=5 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= en-keyword=Water splitting kn-keyword=Water splitting en-keyword=Transition metal dichalcogenide kn-keyword=Transition metal dichalcogenide en-keyword=Hydrogen evolution kn-keyword=Hydrogen evolution en-keyword=Photocatalyst kn-keyword=Photocatalyst en-keyword=Fullerene kn-keyword=Fullerene END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=387 end-page=399 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon inhalation as a low-dose radiation. en-copyright= kn-copyright= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=radon inhalation kn-keyword=radon inhalation en-keyword=proteomics kn-keyword=proteomics en-keyword=multivariate analysis kn-keyword=multivariate analysis en-keyword=brain kn-keyword=brain en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=416 cd-vols= no-issue=28 article-no= start-page=6679 end-page=6686 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of protein immobilization methods with covalent bonding on paper for paper-based enzyme-linked immunosorbent assay en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, two methods were examined to optimize the immobilization of antibodies on paper when conducting a paper-based enzyme-linked immunosorbent assay (P-ELISA). Human IgG, as a test-capture protein, was immobilized on paper via the formation of Schiff bases. Aldehyde groups were introduced onto the surface of the paper via two methods: NaIO4 and 3-aminopropyltriethoxysilane (APTS) with glutaraldehyde (APTS-glutaraldehyde). In the assay, horseradish peroxidase-conjugated anti-human IgG (HRP-anti-IgG) binds to the immobilized human IgG, and the colorimetric reaction of 3,3′,5,5′-tetramethylbenzyzine (TMB) produces a blue color in the presence of H2O2 and HRP-anti-IgG as a model analyte. The immobilization of human IgG, the enzymatic reaction conditions, and the reduction of the chemical bond between the paper surface and immobilized human IgG all were optimized in order to improve both the analytical performance and the stability. In addition, the thickness of the paper was examined to stabilize the analytical signal. Consequently, the APTS-glutaraldehyde method was superior to the NaIO4 method in terms of sensitivity and reproducibility. Conversely, the reduction of imine to amine with NaBH4 proved to exert only minimal influence on sensitivity and stability, although it tended to degrade reproducibility. We also found that thick paper was preferential when using P-ELISA because a rigid paper substrate prevents distortion of the paper surface that is often caused by repeated washing processes. en-copyright= kn-copyright= en-aut-name=ChenYang en-aut-sei=Chen en-aut-mei=Yang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Paper-based enzyme-linked immunosorbent assay kn-keyword=Paper-based enzyme-linked immunosorbent assay en-keyword=ELISA kn-keyword=ELISA en-keyword=Immobilization kn-keyword=Immobilization en-keyword=Covalent bonding kn-keyword=Covalent bonding en-keyword=Protein kn-keyword=Protein END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=1 article-no= start-page=2400604 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elastomer Particle Monolayers Formed by the Compression of Poly(methyl acrylate) Microparticles at an Air/Water Interface en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the previous study (Green Chem., 2023, 25, 3418), highly stretchable and mechanically tough poly(methyl acrylate) (pMA) microparticle-based elastomers can be formed by drying a microparticle-containing aqueous dispersion. This discovery has the potential to overcome the mechanical weakness of industrially produced aqueous latex films. However, in 3D-arranged particle films, structural complexity, such as the existence of defects, makes it difficult to clearly understand the relationship between the particle film structure and its mechanical properties. In this study, 2D-ordered pMA particle monolayers at the air/water interface of a Langmuir trough are prepared. Under high compression at the air/water interface, the microparticles contact their neighboring particles, and the resulting monolayers can be successfully transferred onto a solid substrate. The compression of the monolayer films is linked to an increase in the elastic modulus of the monolayer film on the solid substrate as evident from the local Young's modulus mapping using atomic force microscopy. Thus, pMA particle films with different mechanical properties can be created using a Langmuir trough. en-copyright= kn-copyright= en-aut-name=SasakiYuma en-aut-sei=Sasaki en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishizawaYuichiro en-aut-sei=Nishizawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeNatsuki en-aut-sei=Watanabe en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchihashiTakayuki en-aut-sei=Uchihashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiDaisuke en-aut-sei=Suzuki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Nagoya University kn-affil= affil-num=4 en-affil=Department of Physics, Nagoya University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Langmuir–Blodgett techniques kn-keyword=Langmuir–Blodgett techniques en-keyword=polymer colloids kn-keyword=polymer colloids en-keyword=polymer structures kn-keyword=polymer structures en-keyword=thin films kn-keyword=thin films en-keyword=tough materials kn-keyword=tough materials END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue= article-no= start-page=1560 end-page=1571 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines under mild conditions with a proton-exchange membrane reactor en-subtitle= kn-subtitle= en-abstract= kn-abstract=An electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines using a proton-exchange membrane (PEM) reactor was developed.

The quinoline reduction was efficiently promoted by adding a catalytic amount of p-toluenesulfonic acid (PTSA) or pyridinium p-toluenesulfonate (PPTS). Pyridine was also reduced to piperidine in the presence of PTSA. en-copyright= kn-copyright= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsakiAtsushi en-aut-sei=Osaki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueHaruka en-aut-sei=Inoue en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShidaNaoki en-aut-sei=Shida en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AtobeMahito en-aut-sei=Atobe en-aut-mei=Mahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugaSeiji en-aut-sei=Suga en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Engineering Science and Advanced Chemical Energy Research Center, Yokohama National University kn-affil= affil-num=6 en-affil=Graduate School of Engineering Science and Advanced Chemical Energy Research Center, Yokohama National University kn-affil= affil-num=7 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cyanoarene kn-keyword=cyanoarene en-keyword=nitroarene kn-keyword=nitroarene en-keyword=PEM reactor kn-keyword=PEM reactor en-keyword=pyridine kn-keyword=pyridine en-keyword=quinoline kn-keyword=quinoline END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=259 end-page=270 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of the Lipid Profile and Oxidative Stress in Fatigue, Sleep Disorders and Cognitive Impairment in Patients with Multiple Sclerosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the relationship of the lipid profile, dysfunctional high-density lipoprotein, ischaemia-modified albumin and thiol–disulfide homeostasis with cognitive impairment, fatigue and sleep disorders in patients with multiple sclerosis. The cognitive functions of patients were evaluated with the Brief International Cognitive Assessment for Multiple Sclerosis battery. Fatigue was evaluated with the Fatigue Severity Scale and the Fatigue Impact Scale. The Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale were used to assess patients’ sleep disturbance. Peripheral blood samples were collected, and lipid levels and myeloperoxidase and paraoxonase activity were measured. The myeloperoxidase/paraoxonase ratio, which indicates dysfunctional high-density lipoprotein, was calculated. Thiol–disulfide homeostasis and ischaemia-modified albumin were measured.
We did not identify any relationship between dysfunctional high-density lipoprotein and the physical disability, cognitive decline, fatigue and sleep problems of multiple sclerosis. Thiol–disulfide homeostasis was associated with cognitive scores. The shift of the balance towards disulfide was accompanied by a decrease in cognitive scores. On the other hand, we did not detect any relationship between fatigue and sleep disorders and thiol–disulfide homeostasis. Our findings revealed a possible correlation between cognitive dysfunction and thiol–disulfide homeostasis in multiple sclerosis patients. en-copyright= kn-copyright= en-aut-name=VuralGonul en-aut-sei=Vural en-aut-mei=Gonul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DemirEsra en-aut-sei=Demir en-aut-mei=Esra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GumusyaylaSadiye en-aut-sei=Gumusyayla en-aut-mei=Sadiye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ErenFunda en-aut-sei=Eren en-aut-mei=Funda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BarakliSerdar en-aut-sei=Barakli en-aut-mei=Serdar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NeseliogluSalim en-aut-sei=Neselioglu en-aut-mei=Salim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ErelOzcan en-aut-sei=Erel en-aut-mei=Ozcan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=2 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=4 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=5 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=7 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= en-keyword=multiple sclerosis kn-keyword=multiple sclerosis en-keyword=dysfunctional HDL kn-keyword=dysfunctional HDL en-keyword=thiol–disulfide homeostasis kn-keyword=thiol–disulfide homeostasis en-keyword=cognitive decline kn-keyword=cognitive decline END start-ver=1.4 cd-journal=joma no-vol=146 cd-vols= no-issue=22 article-no= start-page=14935 end-page=14941 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Skeletal Formation of Carbocycles with CO2: Selective Synthesis of Indolo[3,2-b]carbazoles or Cyclophanes from Indoles, CO2, and Phenylsilane en-subtitle= kn-subtitle= en-abstract= kn-abstract=The catalytic reactions of indoles with CO2 and phenylsilane afforded indolo[3,2-b]carbazoles, where the fused benzene ring was constructed by forming two C–H bonds and four C–C bonds with two CO2 molecules via deoxygenative conversions.

We previously reported that the large Li+-ion transference number in sulfolane (SL)-based HCEs, attributed to the unique exchange/hopping-like Li+-ion conduction, decreased upon dilution with the non-coordinating hydrofluoroether (HFE) despite the retention of the local Li+-ion coordination structure. Therefore, in this study, we investigated the effects of HFE dilution on the Li+ transference number and the solution structure of SL-based LHCEs via the analysis of dynamic ion correlations and molecular dynamics simulations. The addition of HFE caused nano-segregation in the SL-based LHCEs to afford polar and nonpolar domains and fragmentation of the polar ion-conducting pathway into smaller clusters with increasing HFE content. Analysis of the dynamic ion correlations revealed that the anti-correlated Li+–Li+ motions were more pronounced upon HFE addition, suggesting that the Li+ exchange/hopping conduction is obstructed by the non-ion-conducting HFE-rich domains. Thus, the HFE addition affects the entire solution structure and ion transport without significantly affecting the local Li+-ion coordination structure. Further studies on ion transport in LHCEs would help obtain a design principle for liquid electrolytes with high ionic conductivity and large Li+-ion transference numbers. en-copyright= kn-copyright= en-aut-name=SudohTaku en-aut-sei=Sudoh en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaShuhei en-aut-sei=Ikeda en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigenobuKeisuke en-aut-sei=Shigenobu en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuzukiSeiji en-aut-sei=Tsuzuki en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DokkoKaoru en-aut-sei=Dokko en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanabeMasayoshi en-aut-sei=Watanabe en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UenoKazuhide en-aut-sei=Ueno en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Taku Sudoh Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=2 en-affil=Department of Materials Chemistry, Nagoya University kn-affil= affil-num=3 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=4 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=5 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=6 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science and Department of Chemistry, Okayama University kn-affil= affil-num=8 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=14 article-no= start-page=144304 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis on high-resolution spectrum of the S1–S0 transition of free-base phthalocyanine en-subtitle= kn-subtitle= en-abstract= kn-abstract=A high-resolution absorption spectrum of the S-1-S-0 transition of free-base phthalocyanine was observed and analyzed with improved reliability. The spectrum, with a partially resolved rotational structure, was obtained by using the buffer-gas cooling technique and a single-mode tunable laser. Our new analysis reveals that the S-1 <- S-0 0(0)(0) band belongs to the a-type transition, where the electronic transition moment aligns parallel to the NH-HN direction, allowing the assignment of the S-1 state to B-1(3u). These results agree with a prior study using supersonic expansion and are well supported by theoretical calculations. Interestingly, the rotational constant B in the S-1 state, which is often smaller than that in the ground state for typical molecules, was found to be slightly larger than that in the S-0 (1)A(g) state. This suggests a change in the character of pi bonds with the electronic excitation. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaNaofumi en-aut-sei=Nakayama en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=4 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=5 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=6 en-affil=CONFLEX Corporation kn-affil= affil-num=7 en-affil=Molecular Photoscience Research Center, Kobe University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=249 cd-vols= no-issue= article-no= start-page=440 end-page=452 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=How do water-mediated interactions and osmotic second virial coefficients vary with particle size? en-subtitle= kn-subtitle= en-abstract= kn-abstract=We examine quantitatively the solute-size dependences of the effective interactions between nonpolar solutes in water and in a simple liquid. The potential w(r) of mean force and the osmotic second virial coefficients B are calculated with high accuracy from molecular dynamics simulations. As the solute diameter increases from methane's to C60's with the solute–solute and solute–solvent attractive interaction parameters fixed to those for the methane–methane and methane–water interactions, the first minimum of w(r) lowers from −1.1 to −4.7 in units of the thermal energy kT. Correspondingly, the magnitude of B (<0) increases proportional to σα with some power close to 6 or 7, which reinforces the solute-size dependence of B found earlier for a smaller range of σ [H. Naito, R. Okamoto, T. Sumi and K. Koga, J. Chem. Phys., 2022, 156, 221104]. We also demonstrate that the strength of the attractive interactions between solute and solvent molecules can qualitatively change the characteristics of the effective pair interaction between solute particles, both in water and in a simple liquid. If the solute–solvent attractive force is set to be weaker (stronger) than a threshold, the effective interaction becomes increasingly attractive (repulsive) with increasing solute size. en-copyright= kn-copyright= en-aut-name=NaitoHidefumi en-aut-sei=Naito en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=95 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Roles of Neuropeptide Y in Respiratory Disease Pathogenesis via the Airway Immune Response en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. en-copyright= kn-copyright= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=neuropeptide y kn-keyword=neuropeptide y en-keyword=Y1 receptor kn-keyword=Y1 receptor en-keyword=airway immune response kn-keyword=airway immune response en-keyword=bronchial epithelial cells kn-keyword=bronchial epithelial cells en-keyword=respiratory disease kn-keyword=respiratory disease END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=9 article-no= start-page=094101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=GenIce-core: Efficient algorithm for generation of hydrogen-disordered ice structures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ice is different from ordinary crystals because it contains randomness, which means that statistical treatment based on ensemble averaging is essential. Ice structures are constrained by topological rules known as the ice rules, which give them unique anomalous properties. These properties become more apparent when the system size is large. For this reason, there is a need to produce a large number of sufficiently large crystals that are homogeneously random and satisfy the ice rules. We have developed an algorithm to quickly generate ice structures containing ions and defects. This algorithm is provided as an independent software module that can be incorporated into crystal structure generation software. By doing so, it becomes possible to simulate ice crystals on a previously impossible scale. en-copyright= kn-copyright= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=3 en-affil=Toyota Physical and Chemical Research Institute kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Macrophages in Liver Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liver fibrosis, which ultimately leads to liver cirrhosis and hepatocellular carcinoma, is a major health burden worldwide. The progression of liver fibrosis is the result of the wound-healing response of liver to repeated injury. Hepatic macrophages are cells with high heterogeneity and plasticity and include tissue-resident macrophages termed Kupffer cells, and recruited macrophages derived from circulating monocytes, spleen and peritoneal cavity. Studies have shown that hepatic macrophages play roles in the initiation and progression of liver fibrosis by releasing inflammatory cytokines/chemokines and pro-fibrogenic factors. Furthermore, the development of liver fibrosis has been shown to be reversible. Hepatic macrophages have been shown to alternately regulate both the regression and turnover of liver fibrosis by changing their phenotypes during the dynamic progression of liver fibrosis. In this review, we summarize the role of hepatic macrophages in the progression and regression of liver fibrosis. en-copyright= kn-copyright= en-aut-name=SunCuiming en-aut-sei=Sun en-aut-mei=Cuiming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ERK-MAPK kn-keyword=ERK-MAPK en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=fibrosis kn-keyword=fibrosis en-keyword=macrophages kn-keyword=macrophages END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=11 article-no= start-page=e202302963 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On Demand Synthesis of C3−N1’ Bisindoles by a Formal Umpolung Strategy: First Total Synthesis of (±)‐Rivularin A en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this work, a straightforward synthesis of C3−N1’ bisindolines is achieved by a formal umpolung strategy.

CG force fields (FFs) in these MD studies often use implicit or nonpolar water models to reduce computational costs. CG-MD using water models cannot properly describe electrostatic screening effects owing to the hydration of ionic segments and thus cannot appropriately describe molecular events involving water channels and pores through lipid membranes. To overcome this issue, we developed a protein model in the pSPICA FF, in which a polar CG water model showing the proper dielectric response was adopted. The developed CG model greatly improved the transfer free energy profiles of charged side chain analogues across the lipid membrane. Application studies on melittin-induced membrane pores and mechanosensitive channels in lipid membranes demonstrated that CG-MDs using the pSPICA FF correctly reproduced the structure and stability of the pores and channels. Furthermore, the adsorption behavior of the highly charged nona-arginine peptides on lipid membranes changed with salt concentration, indicating the pSPICA FF is also useful for simulating protein adsorption on membrane surfaces. en-copyright= kn-copyright= en-aut-name=MiyazakiYusuke en-aut-sei=Miyazaki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=4 article-no= start-page=e202301130 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concise Synthesis of Thiazolo[4,5-b]indoles via Ring Switch/Cyclization Sequences en-subtitle= kn-subtitle= en-abstract= kn-abstract=The unexpected reactions of indoline hemiaminals affords 2,5-diaryl-4-hydroxythiazolines through a thioamidation/ring switch sequence. The key to success of this transformation is to use a thioamide as a thiazoline precursor under transient tautomeric control. This transformation features mild reaction conditions and good yields with broad functional group tolerance (17 examples, up to 99 % yield). Further transformations of the thiazolines provide a direct entry to dihydrothiazolo[4,5-b]indoles and thiazolo[4,5-b]indoles. en-copyright= kn-copyright= en-aut-name=YamadaKoji en-aut-sei=Yamada en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsubogoTetsu en-aut-sei=Tsubogo en-aut-mei=Tetsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanazawaHikaru en-aut-sei=Kanazawa en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshizukaSayaka en-aut-sei=Ishizuka en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhyamaKoutaro en-aut-sei=Ohyama en-aut-mei=Koutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaidaMasaki en-aut-sei=Kaida en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=2 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=3 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=4 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=5 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=6 en-affil=Faculty of Pharmaceutical Sciences, Health Sciences University of Hokkaido kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=hemiaminals kn-keyword=hemiaminals en-keyword=indoles kn-keyword=indoles en-keyword=ring-switch kn-keyword=ring-switch en-keyword=thiazolo[4.5-b]indoles kn-keyword=thiazolo[4.5-b]indoles en-keyword=thioamides kn-keyword=thioamides END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=47 article-no= start-page=e202300835 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical Coupling Reactions Using Non‐Transition Metal Mediators: Recent Advances en-subtitle= kn-subtitle= en-abstract= kn-abstract=Indirect electrolysis method using appropriate mediators enables numerous chemical reactions.

VDR antagonists may be able to inhibit tumors that overexpress VDR. However, the current antagonists are arduous to synthesize and are only partial antagonists, limiting their use. Here, we show that the VDR antagonist MeTC7 (5), which can be synthesized from 7-dehydrocholesterol (6) in two steps, inhibits VDR selectively, suppresses the viability of cancer cell-lines, and reduces the growth of the spontaneous transgenic TH-MYCN neuroblastoma and xenografts in vivo. The VDR selectivity of 5 against RXRα and PPAR-γ was confirmed, and docking studies using VDR-LBD indicated that 5 induces major changes in the binding motifs, which potentially result in VDR antagonistic effects. These data highlight the therapeutic benefits of targeting VDR for the treatment of malignancies and demonstrate the creation of selective VDR antagonists that are easy to synthesize. en-copyright= kn-copyright= en-aut-name=KhazanNegar en-aut-sei=Khazan en-aut-mei=Negar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimKyu Kwang en-aut-sei=Kim en-aut-mei=Kyu Kwang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HansenJeanne N. en-aut-sei=Hansen en-aut-mei=Jeanne N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SinghNiloy A. en-aut-sei=Singh en-aut-mei=Niloy A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MooreTaylor en-aut-sei=Moore en-aut-mei=Taylor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SnyderCameron W.

Patients with Schizophrenia en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the relationship between serum tumor necrosis factor-alpha (TNF-α) levels and psychopathological symptoms, clinical and socio-demographic characteristics and antipsychotic therapy in individuals with schizophrenia. TNF-α levels were measured in 90 patients with schizophrenia and 90 healthy controls matched by age, gender, smoking status, and body mass index. The Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of psychopathology in patients. No significant differences in TNF-α levels were detected between the patients and controls (p=0.736). TNF-α levels were not correlated with total, positive, negative, general, or composite PANSS scores (all p>0.05). A significant negative correlation was observed between TNF-α levels and the PANSS cognitive factor (ρ=−0.222, p=0.035). A hierarchical regression analysis identified the cognitive factor as a significant predictor of the TNF-α level (beta=−0.258, t=−2.257, p=0.027). There were no significant differences in TNF-α levels among patients treated with different types of antipsychotics (p=0.596). TNF-α levels correlated positively with the age of onset (ρ=0.233, p=0.027) and negatively with illness duration (ρ=−0.247, p=0.019) and antipsychotic treatment duration (ρ=−0.256, p=0.015). These results indicate that TNF-α may be involved in cognitive impairment in schizophrenia, and would be a potential clinical-state marker in schizophrenia. en-copyright= kn-copyright= en-aut-name=PavlovicMarko en-aut-sei=Pavlovic en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabicDragan en-aut-sei=Babic en-aut-mei=Dragan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RastovicPejana en-aut-sei=Rastovic en-aut-mei=Pejana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArapovicJurica en-aut-sei=Arapovic en-aut-mei=Jurica kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinacMarko en-aut-sei=Martinac en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JakovacSanja en-aut-sei=Jakovac en-aut-mei=Sanja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BarbaricRomana en-aut-sei=Barbaric en-aut-mei=Romana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=2 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=3 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=4 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=5 en-affil=Health Care Center Mostar, University of Mostar kn-affil= affil-num=6 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=7 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= en-keyword=tumor necrosis factor-alpha kn-keyword=tumor necrosis factor-alpha en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=psychopathology kn-keyword=psychopathology en-keyword=immune system kn-keyword=immune system END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=387 end-page=394 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=No epidemiological studies have examined the health effects of daily bathing in radon hot springs. In this cross-sectional study, we investigated the associations between radon hot spring bathing and health conditions. The target population was 5,250 adults ≥ 20 years old in the town of Misasa, Japan. We collected information about the participants’ bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoYuki en-aut-sei=Fujimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YukimineRyohei en-aut-sei=Yukimine en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Longevity and Social Medicine (Geriatrics), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=radon hot spring kn-keyword=radon hot spring en-keyword=bathing habit kn-keyword=bathing habit en-keyword=self-rated health kn-keyword=self-rated health en-keyword=cross-section study kn-keyword=cross-section study END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=359 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes in TRPV1 Receptor, CGRP, and BDNF Expression in Rat Dorsal Root Ganglion with Resiniferatoxin-Induced Neuropathic Pain: Modulation by Pulsed Radiofrequency Applied to the Sciatic Nerve en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulsed radiofrequency (PRF) is a safe method of treating neuropathic pain by generating intermittent electric fields at the needle tip. Resiniferatoxin (RTX) is an ultrapotent agonist of transient receptor potential vanilloid subtype-1 (TRPV1) receptors. We investigated the mechanism of PRF using a rat model of RTX-induced neuropathic pain. After administering RTX intraperitoneally, PRF was applied to the right sciatic nerve. We observed the changes in TRPV1, calcitonin gene-related peptide (CGRP), and brain-derived neurotrophic factor (BDNF) in the dorsal root ganglia by western blotting. Expressions of TRPV1 and CGRP were significantly lower in the contralateral (RTX-treated, PRF-untreated) tissue than in control rats (p<0.0001 and p<0.0001, respectively) and the ipsilateral tissues (p<0.0001 and p<0.0001, respectively). BDNF levels were significantly higher in the contralateral tissues than in the control rats (p<0.0001) and the ipsilateral tissues (p<0.0001). These results suggest that, while TRPV1 and CGRP are decreased by RTX-induced neuronal damage, increased BDNF levels result in pain development. PRF may promote recovery from neuronal damage with concomitant restoration of TRPV1 and CGRP, and exert its analgesic effect by reversing BDNF increase. Further research is required to understand the role of TRPV1 and CGRP restoration in improving mechanical allodynia. en-copyright= kn-copyright= en-aut-name=KoshidaTomohiro en-aut-sei=Koshida en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MarutaToyoaki en-aut-sei=Maruta en-aut-mei=Toyoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaNobuhiko en-aut-sei=Tanaka en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidakaKotaro en-aut-sei=Hidaka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurogiMio en-aut-sei=Kurogi en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NemotoTakayuki en-aut-sei=Nemoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YanagitaToshihiko en-aut-sei=Yanagita en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeyaRyu en-aut-sei=Takeya en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsuneyoshiIsao en-aut-sei=Tsuneyoshi en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=3 en-affil=Tanaka homecare clinic kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=6 en-affil=Department of Pharmacology, Faculty of Medicine, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology, School of Nursing, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=8 en-affil=Department of Pharmacology, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=9 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= en-keyword=pulsed radiofrequency kn-keyword=pulsed radiofrequency en-keyword=resiniferatoxin kn-keyword=resiniferatoxin en-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) kn-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) en-keyword=calcitonin gene-related peptide (CGRP) kn-keyword=calcitonin gene-related peptide (CGRP) en-keyword=brain-derived neurotrophic factor (BDNF) kn-keyword=brain-derived neurotrophic factor (BDNF) END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=3 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sound velocity and elastic properties of Fe–Ni–S–Si liquid: the effects of pressure and multiple light elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fe–Ni–S–Si alloy is considered to be one of the plausible candidates of Mercury core material. Elastic properties of Fe–Ni–S–Si liquid are important to reveal the density profile of the Mercury core. In this study, we measured the P-wave velocity (VP) of Fe–Ni–S–Si (Fe73Ni10S10Si7, Fe72Ni10S5Si13, and Fe67Ni10S10Si13) liquids up to 17 GPa and 2000 K to study the effects of pressure, temperature, and multiple light elements (S and Si) on the VP and elastic properties.
The VP of Fe–Ni–S–Si liquids are less sensitive to temperature. The effect of pressure on the VP are close to that of liquid Fe and smaller than those of Fe–Ni–S and Fe–Ni–Si liquids. Obtained elastic properties are KS0 = 99.1(9.4) GPa, KS’ = 3.8(0.1) and ρ0 =6.48 g/cm3 for S-rich Fe73Ni10S10Si7 liquid and KS0 = 112.1(1.5) GPa, KS’ = 4.0(0.1) and ρ0=6.64 g/cm3 for Si-rich Fe72Ni10S5Si13 liquid. The VP of Fe–Ni–S–Si liquids locate in between those of Fe–Ni–S and Fe–Ni–Si liquids. This suggests that the effect of multiple light element (S and Si) on the VP is suppressed and cancel out the effects of single light elements (S and Si) on the VP. The effect of composition on the EOS in the Fe–Ni–S–Si system is indispensable to estimate the core composition combined with the geodesy data of upcoming Mercury mission. en-copyright= kn-copyright= en-aut-name=YamadaIori en-aut-sei=Yamada en-aut-mei=Iori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TerasakiHidenori en-aut-sei=Terasaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrakawaSatoru en-aut-sei=Urakawa en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoTadashi en-aut-sei=Kondo en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MachidaAkihiko en-aut-sei=Machida en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TangeYoshinori en-aut-sei=Tange en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HigoYuji en-aut-sei=Higo en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Earth and Space Science, Osaka University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth and Space Science, Osaka University kn-affil= affil-num=5 en-affil=Synchrotron Radiation Research Center, National Institutes for Quantum Science and Technology (QST) kn-affil= affil-num=6 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= affil-num=7 en-affil=Japan Synchrotron Radiation Research Institute kn-affil= en-keyword=Fe alloy kn-keyword=Fe alloy en-keyword=Sound velocity kn-keyword=Sound velocity en-keyword=Liquid kn-keyword=Liquid en-keyword=Core kn-keyword=Core en-keyword=Mercury kn-keyword=Mercury en-keyword=Light element kn-keyword=Light element END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=243 end-page=254 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Brown Adipose Tissue PPARγ Is Required for the Insulin-Sensitizing Action of Thiazolidinediones en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brown adipose tissue (BAT) plays a critical role in metabolic homeostasis. BAT dysfunction is associated with the development of obesity through an imbalance between energy expenditure and energy intake. The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is the master regulator of adipogenesis. However, the roles of PPARγ and thiazolidinediones (TZDs) in the regulation of BAT metabolism remain unclear. TZDs, which are selective PPARγ activators, improve systemic insulin resistance in animals and humans. In the present study, we generated brown adipocyte-specific PPARγ-deficient mice (BATγKO) to examine the in vivo roles of PPARγ and TZDs in BAT metabolism. In electron microscopic examinations, brown adipocyte-specific PPARγ deletion promoted severe whitening of brown fat and morphological alteration of mitochondria. Brown adipocyte-specific PPARγ deletion also reduced mRNA expression of BAT-selective genes. Although there was no difference in energy expenditure between control and BATγKO mice in calorimetry, norepinephrine-induced thermogenesis was impaired in BATγKO mice. Moreover, pioglitazone treatment improved diet-induced insulin resistance in the control mice but not in the BATγKO mice. These findings suggest that BAT PPARγ is necessary for the maintenance of brown adipocyte function and for the insulin-sensitizing action of TZDs. en-copyright= kn-copyright= en-aut-name=ShibataYusuke en-aut-sei=Shibata en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PPARγ kn-keyword=PPARγ en-keyword=brown adipose tissue kn-keyword=brown adipose tissue en-keyword=thiazolidinediones kn-keyword=thiazolidinediones END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=長時間酸処理したチタン-6アルミニウム-4バナジウム合金の即時軟組織接着性と機械的性質 kn-title=Immediate soft-tissue adhesion and the mechanical properties of the Ti–6Al–4V alloy after long-term acid treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WangYaming en-aut-sei=Wang en-aut-mei=Yaming kn-aut-name=王亜明 kn-aut-sei=王 kn-aut-mei=亜明 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=象牙質初期石灰化における象牙芽細胞膜由来リン脂質の役割 kn-title=Important roles of odontoblast membrane phospholipids in early dentin mineralization en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ANADARisa en-aut-sei=ANADA en-aut-mei=Risa kn-aut-name=穴田理嵯 kn-aut-sei=穴田 kn-aut-mei=理嵯 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=714 end-page=721 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Catalytic enantioselective nucleophilic desymmetrization of phosphonate esters en-subtitle= kn-subtitle= en-abstract= kn-abstract=Molecules that contain a stereogenic phosphorus atom are crucial to medicine, agrochemistry and catalysis. While methods are available for the selective construction of various chiral organophosphorus compounds, catalytic enantioselective approaches for their synthesis are far less common. Given the vastness of possible substituent combinations around a phosphorus atom, protocols for their preparation should also be divergent, providing facile access not only to one but to many classes of phosphorus compounds. Here we introduce a catalytic and enantioselective strategy for the preparation of an enantioenriched phosphorus(V) centre that can be diversified enantiospecifically to a wide range of biologically relevant phosphorus(V) compounds. The process, which involves an enantioselective nucleophilic substitution catalysed by a superbasic bifunctional iminophosphorane catalyst, can accommodate a wide range of carbon substituents at phosphorus. The resulting stable, yet versatile, synthetic intermediates can be combined with a multitude of medicinally relevant O-, N- and S-based nucleophiles. en-copyright= kn-copyright= en-aut-name=FormicaMichele en-aut-sei=Formica en-aut-mei=Michele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RogovaTatiana en-aut-sei=Rogova en-aut-mei=Tatiana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiHeyao en-aut-sei=Shi en-aut-mei=Heyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaharaNaoto en-aut-sei=Sahara en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FerkoBranislav en-aut-sei=Ferko en-aut-mei=Branislav kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FarleyAlistair J.

An endodontic sealer that is both bactericidal and biocompatible is essential for the success of root canal treatments. This is one of the vital issues yet to be solved in clinical dental practice. This in vitro study assessed the effectiveness of graphene oxide (GO) composites GO-CaF2 and GO-Ag-CaF2 as endodontic sealer materials. Dentin slices were coated with either the GO-based composites or commonly used root canal sealers (non-eugenol zinc oxide sealer). The coated slices were treated in 0.9% NaCl, phosphate-buffered saline (PBS), and simulated body fluid (SBF) at 37˚C for 24 hours to compare their sealing effect on the dentin surface. In addition, the radiopacity of these composites was examined to assess whether they complied with the requirements of a sealer for good radiographic visualization. Scanning electron microscopy showed the significant sealing capability of the composites as coating materials. Radiographic images confirmed their radiopacity. Mineral deposition indicated their bioactivity, especially of GO-Ag-CaF2, and thus it is potential for regenerative application. They were both previously shown to be bactericidal to oral microbes and cytocompatible with host cells. With such a unique assemblage of critical properties, these GO-based composites show promise as endodontic sealers for protection against reinfection in root canal treatment and enhanced success in endodontic treatment overall. en-copyright= kn-copyright= en-aut-name=Mohammed Zahedul Islam Nizami en-aut-sei=Mohammed Zahedul Islam Nizami en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GorduysusMelahat en-aut-sei=Gorduysus en-aut-mei=Melahat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AriasZulema en-aut-sei=Arias en-aut-mei=Zulema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=6 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=bioactive sealer kn-keyword=bioactive sealer en-keyword=graphene oxide kn-keyword=graphene oxide en-keyword=mineral deposition kn-keyword=mineral deposition en-keyword=antimicrobial activity kn-keyword=antimicrobial activity en-keyword=radiopacity kn-keyword=radiopacity END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=661 end-page=671 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Genetic Polymorphism with Taxane-induced Peripheral Neuropathy: Sub-analysis of a Randomized Phase II Study to Determine the Optimal Dose of 3-week Cycle Nab-Paclitaxel in Metastatic Breast Cancer Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chemotherapy-induced peripheral neuropathy (CIPN) is an important clinical challenge that threatens patients’ quality of life. This sub-study of the ABROAD trial investigated the influence of single nucleotide polymorphisms (SNPs) on CIPN, using genotype data from a randomized study to determine the optimal dose of a 3-week-cycle regimen of nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). Patients with HER2-negative MBC were randomly assigned to three doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2). Five SNPs (EPHA4-rs17348202, EPHA5-rs7349683, EPHA6-rs301927, LIMK2-rs5749248, and XKR4-rs4737264) were analyzed based on the results of a previous genome-wide association study. Per-allele SNP associations were assessed by a Cox regression to model the cumulative dose of nab-PTX up to the onset of severe or worsening sensory neuropathy. A total of 141 patients were enrolled in the parent study; 91(65%) were included in this sub-study. Worsening of CIPN was significantly greater in the cases with XKR4 AC compared to those with a homozygote AA (HR 1.86, 95%CI: 1.00001−3.46, p=0.049). There was no significant correlation of CIPN with any other SNP. A multivariate analysis showed that the cumulative dose of nab-PTX was most strongly correlated with CIPN (p<0.01). en-copyright= kn-copyright= en-aut-name=AbeYuko en-aut-sei=Abe en-aut-mei=Yuko

kn-title=Viral Sequences Are Repurposed for Controlling Antiviral Responses as Non-Retroviral Endogenous Viral Elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eukaryotic genomes contain numerous copies of endogenous viral elements (EVEs), most of which are considered endogenous retrovirus (ERV) sequences. Over the past decade, non-retroviral endogenous viral elements (nrEVEs) derived from ancient RNA viruses have been discovered. Several functions have been proposed for these elements, including antiviral defense. This review summarizes the current understanding of nrEVEs derived from RNA viruses, particularly endogenous bornavirus-like elements (EBLs) and endogenous filovirus-like elements (EFLs). EBLs are one of the most extensively studied nrEVEs. The EBL derived from bornavirus nucleoprotein (EBLN) is thought to function as a non-coding RNA or protein that regulates host gene expression or inhibits virus propagation. Ebolavirus and marburgvirus, which are filoviruses, induce severe hemorrhagic fever in humans and nonhuman primates. Although the ecology of filoviruses remains unclear, bats are believed to be potential reservoirs. Based on the knowledge from EBLs, it is postulated that EFLs in the bat genome help to maintain the balance between filovirus infection and the bat’s defense system, which may partially explain why bats act as potential reservoirs. Further research into the functions of nrEVEs could reveal novel antiviral systems and inspire novel antiviral approaches. en-copyright= kn-copyright= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaTomoyuki en-aut-sei=Honda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=EVE kn-keyword=EVE en-keyword=nrEVE kn-keyword=nrEVE en-keyword=bornavirus kn-keyword=bornavirus en-keyword=filovirus kn-keyword=filovirus en-keyword=antiviral kn-keyword=antiviral END start-ver=1.4 cd-journal=joma no-vol=629 cd-vols= no-issue= article-no= start-page=238 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acidic layer-enhanced nanoconfinement of anions in cylindrical pore of single-walled carbon nanotube en-subtitle= kn-subtitle= en-abstract= kn-abstract=The adsorption of the nitrate ion by the cylindrical pore of single-walled carbon nanotubes (SWCNT) was found to be aided by an acidic adsorbed layer. Adsorbed water in the vicinity of the pore wall can supply protons through ionization, forming the acidic layer, according to Raman spectra and results of solution pH fluctuations caused by ion species adsorption. Such an acidic adsorbed layer leads to surplus adsorption of anionic species where the adsorbed amount of nitrate ions is much larger than that of cations. Also, we could observe the Raman bands being assignable to the symmetrical stretching mode at an extremely highfrequency region for nano-restricted nitrate ions compared to any other bulk phases. The abnormal band shift of adsorbed nitrate ions indicates that the nitrate ions are confined in the pore under the effects of nanoconfinement by the pore and the strong interaction with the acidic layer in the pore. Our results warn that we have to construct the adsorption model of aqueous electrolytes confined in carbon pores by deliberating the acid layer formed by the adsorbed water. en-copyright= kn-copyright= en-aut-name=OhkuboTakahiro en-aut-sei=Ohkubo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakayasuHiroki en-aut-sei=Nakayasu en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeuchiYuki en-aut-sei=Takeuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurodaYasushige en-aut-sei=Kuroda en-aut-mei=Yasushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Proton kn-keyword=Proton en-keyword=Nitrate ion kn-keyword=Nitrate ion en-keyword=Adsorption kn-keyword=Adsorption en-keyword=Confinement kn-keyword=Confinement en-keyword=Micropore kn-keyword=Micropore en-keyword=Nanospace kn-keyword=Nanospace END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=447 end-page=455 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of the Mechanism and Significance of the Erythrocyte Sedimentation Rate from Clinical Laboratory Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=The erythrocyte sedimentation rate (ESR) is a widely used marker of inflammation, but the detailed mechanisms underlying the ESR remain unclear. We retrospectively collected laboratory data from our hospital’s laboratory information system, and performed multiple linear regression analysis and correlation analysis to determine relationships between the ESR and other laboratory test parameters. The alpha-2, beta-2, and gamma fractions from serum protein electrophoresis, serum immunoglobulin (Ig) G, IgA, IgM, and complement C3 levels, plasma fibrinogen levels, and platelet count showed positive effects on the ESR; however, the serum albumin level showed negative effects. Since erythrocytes are negatively charged, an increase in positively charged proteins and a decrease in negatively charged albumin were suggested to increase the ESR. Notably, C-reactive protein (CRP) showed the third-strongest correlation with the ESR despite having no significant effect on the ESR. We also reviewed cases with discordant ESR and CRP levels to compare the disease profiles of high ESR/low CRP patients and low ESR/high CRP patients. The patients with high ESR/low CRP had a completely different disease profile from those with low ESR/high CRP. Since the ESR and CRP have different roles, they should be used as markers in a context-dependent manner. en-copyright= kn-copyright= en-aut-name=UmemuraHiroshi en-aut-sei=Umemura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukudaYoshiaki en-aut-sei=Fukuda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyashitaTetsuo en-aut-sei=Miyashita en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaTomohiro en-aut-sei=Nakayama en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Laboratory Medicine, Department of Pathology and Microbiology, Nihon University School of Medicine kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory, Nihon University Itabashi Hospital kn-affil= affil-num=3 en-affil=Department of Clinical Laboratory, Nihon University Itabashi Hospital kn-affil= affil-num=4 en-affil=Division of Laboratory Medicine, Department of Pathology and Microbiology, Nihon University School of Medicine kn-affil= en-keyword=complement kn-keyword=complement en-keyword=erythrocyte sedimentation rate kn-keyword=erythrocyte sedimentation rate en-keyword=fibrinogen kn-keyword=fibrinogen en-keyword=immunoglobulin kn-keyword=immunoglobulin en-keyword=serum protein electrophoresis kn-keyword=serum protein electrophoresis END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=373 end-page=383 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Central and Enteric Neuroprotective Effects by Eucommia ulmoides Extracts on Neurodegeneration in Rotenone-induced Parkinsonian Mouse en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson’s disease (PD) is a progressive neurodegenerative disease of both the central and peripheral / enteric nervous systems. Oxidative stress and neuroinflammation are associated with the pathogenesis of PD, suggesting that anti-oxidative and anti-inflammatory compounds could be neuroprotective agents for PD. Eucommia ulmoides (EU) is a traditional herbal medicine which exerts neuroprotective effects by anti-inflammatory and anti-oxidative properties. Our previous study showed that treatment with chlorogenic acid, a component of EU, protected against neurodegeneration in the central and enteric nervous systems in a PD model. In this study, we examined the effects of EU extract (EUE) administration on dopaminergic neurodegeneration, glial response and α-synuclein expression in the substantia nigra pars compacta (SNpc), and intestinal enteric neurodegeneration in low-dose rotenone-induced PD model mice. Daily oral administration of EUE ameliorated dopaminergic neurodegeneration and α-synuclein accumulation in the SNpc. EUE treatment inhibited rotenone- induced decreases in the number of total astrocytes and in those expressing the antioxidant molecule metallothionein. EUE also prevented rotenone-induced microglial activation. Furthermore, EUE treatment exerted protective effects against intestinal neuronal loss in the PD model. These results suggest that EU exerts neuroprotective effects in the central and enteric nervous systems of rotenone-induced parkinsonism mice, in part by glial modification. en-copyright= kn-copyright= en-aut-name=ImafukuFuminori en-aut-sei=Imafuku en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SunJin en-aut-sei=Sun en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamimaiSunao en-aut-sei=Kamimai en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimizuTakashi en-aut-sei=Shimizu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyotaToshiaki en-aut-sei=Toyota en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkamotoYusei en-aut-sei=Okamoto en-aut-mei=Yusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IsookaNami en-aut-sei=Isooka en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KikuokaRyo en-aut-sei=Kikuoka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KitamuraYoshihisa en-aut-sei=Kitamura en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medical Neurobiology, Okayama University Medical School kn-affil= affil-num=5 en-affil=Department of Medical Neurobiology, Okayama University Medical School kn-affil= affil-num=6 en-affil=Department of Medical Neurobiology, Okayama University Medical School kn-affil= affil-num=7 en-affil=Department of Medical Neurobiology, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Eucommia ulmoides kn-keyword=Eucommia ulmoides en-keyword=dopamine neuron kn-keyword=dopamine neuron en-keyword=enteric neuron kn-keyword=enteric neuron en-keyword=glia kn-keyword=glia en-keyword=Parkinson’s disease kn-keyword=Parkinson’s disease END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=359 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic Approaches Targeting miRNA in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. en-copyright= kn-copyright= en-aut-name=Hiramatsu-AsanoSumie en-aut-sei=Hiramatsu-Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=miRNA kn-keyword=miRNA en-keyword=miRNA targeting therapy kn-keyword=miRNA targeting therapy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=9580 end-page=9585 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Annulative coupling of vinylboronic esters: aryne-triggered 1,2-metallate rearrangement en-subtitle= kn-subtitle= en-abstract= kn-abstract=A stereoselective annulative coupling of a vinylboronic ester ate-complex with arynes producing cyclic borinic esters has been developed. An annulation reaction that proceeded through the formation of two C-C bonds and a C-B bond was realized by exploiting a 1,2-metallate rearrangement of boronate triggered by the addition of a vinyl group to the strained triple bond of an aryne. The generated aryl anion would then cyclize to a boron atom to complete the annulation cascade. The annulated borinic ester could be converted to boronic acids and their derivatives by oxidation, halogenation, and cross-coupling. Particularly, halogenation and Suzuki-Miyaura coupling proceeded in a site-selective fashion and produced highly substituted alkylboronic acid derivatives. en-copyright= kn-copyright= en-aut-name=MizoguchiHaruki en-aut-sei=Mizoguchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamadaHidetoshi en-aut-sei=Kamada en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoKazuki en-aut-sei=Morimoto en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaRyuji en-aut-sei=Yoshida en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakakuraAkira en-aut-sei=Sakakura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=156 cd-vols= no-issue=22 article-no= start-page=221104 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220614 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Osmotic second virial coefficients for hydrophobic interactions as a function of solute size en-subtitle= kn-subtitle= en-abstract= kn-abstract=To gain quantitative insight into how the overall strength of the hydrophobic interaction varies with the molecular size, we calculate osmotic second virial coefficients B for hydrophobic spherical molecules of different diameters σ in water based on molecular simulation with corrections to the finite-size and finite-concentration effects. It is shown that B (<0) changes by two orders of magnitude greater as σ increases twofold and its solute-size dependence is best fit by a power law B ∝ σ α with the exponent α ≃ 6, which contrasts with the cubic power law that the second virial coefficients of gases obey. It is also found that values of B for the solutes in a nonpolar solvent are positive but they obey the same power law as in water. A thermodynamic identity for B derived earlier [K. Koga, V. Holten, and B. Widom, J. Phys. Chem. B 119, 13391 (2015)] indicates that if B is asymptotically proportional to a power of σ, the exponent α must be equal to or greater than 6. en-copyright= kn-copyright= en-aut-name=NaitoHidefumi en-aut-sei=Naito en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoRyuichi en-aut-sei=Okamoto en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=22 article-no= start-page=9257 end-page=9263 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Oxygen Vacancy in the Photocarrier Dynamics of WO3 Photocatalysts: The Case of Recombination Centers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Defects in powder photocatalysts determine the photocatalytic activity. The addition of defects sometimes enhances the activity, but sometimes decreases it. However, the factors determining the difference between these cases have not been fully elucidated yet. Herein, we investigated the effects of oxygen vacancies on photocarrier dynamics in WO3 powder using broadband transient absorption spectroscopy. It was found that the decay of deeply trapped electrons was accelerated when the number of oxygen vacancies was increased by H-2 reduction. This result suggests that oxygen vacancies in WO3 mainly act as recombination centers. This is in contrast to many other photocatalysts such as TiO2 and SrTiO3, where the carrier lifetime increases with increasing oxygen vacancy concentration. These differences can be attributed to the difference in the distance between oxygen vacancies. When defects are dispersed, trapped electrons need to travel over long distances by repeatedly hopping and tunneling between defects to combine with holes, resulting in decelerated recombination. In contrast, when the defects are connected or located close together, the trapped electrons can readily migrate among defects, leading to enhanced recombination. Control of the distance between defects is thus important for enhancing photocatalytic activity. en-copyright= kn-copyright= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UemuraYohei en-aut-sei=Uemura en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsakuraKiyotaka en-aut-sei=Asakura en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute for Molecular Science kn-affil= affil-num=3 en-affil=Institute for Catalysis, Hokkaido University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=37 article-no= start-page=e202201253 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Synthesis of Glycosylated Cholera Toxin B Subunit as a Tracer of Glycoprotein Trafficking in Organelles of Living Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glycosylation of proteins is known to be essential for changing biological activity and stability of glycoproteins on the cell surfaces and in body fluids. Delivering of homogeneous glycoproteins into the endoplasmic reticulum (ER) and the Golgi apparatus would enable us to investigate the function of asparagine-linked (N-) glycans in the organelles. In this work, we designed and synthesized an intentionally glycosylated cholera toxin B-subunit (CTB) to be transported to the organelles of mammalian cells. The heptasaccharide, the intermediate structure of various complex-type N-glycans, was introduced to the CTB. The synthesized monomeric glycosyl-CTB successfully entered mammalian cells and was transported to the Golgi and the ER, suggesting the potential use of synthetic CTB to deliver and investigate the functions of homogeneous N-glycans in specific organelles of living cells. en-copyright= kn-copyright= en-aut-name=MakiYuta en-aut-sei=Maki en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawataKazuki en-aut-sei=Kawata en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiuYanbo en-aut-sei=Liu en-aut-mei=Yanbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GooKang‐Ying en-aut-sei=Goo en-aut-mei=Kang‐Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoRyo en-aut-sei=Okamoto en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KajiharaYasuhiro en-aut-sei=Kajihara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=6 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=glycoprotein kn-keyword=glycoprotein en-keyword=N-glycan kn-keyword=N-glycan en-keyword=cholera toxin kn-keyword=cholera toxin en-keyword=native chemical ligation kn-keyword=native chemical ligation en-keyword=live imaging kn-keyword=live imaging END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=281 end-page=290 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histone Demethylase Jmjd3 Regulates the Osteogenic Differentiation and Cytokine Expressions of Periodontal Ligament Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal ligament (PDL) cells are critical for the bone remodeling process in periapical lesions since they can differentiate into osteoblasts and secrete osteoclastogenesis-promoting cytokines. Post-translational histone modifications including alterations of the methylation status of H3K27 are involved in cell differentiation and inflammatory reaction. The histone demethylase Jumonji domain-containing 3 (Jmjd3) specifically removes methylation of H3K27. We investigated whether Jmjd3 is involved in the osteogenic differentiation and secretion of PDL cells’ inflammatory factors. Jmjd3 expression in periapical lesions was examined by immunostaining. Using siRNA specific for Jmjd3 or the specific Jmjd3 inhibitor GSK-J4, we determined Jmjd3’s roles in osteogenic differentiation and cytokine production by real-time RT-PCR. The locations of Jmjd3 and NF-κB were analyzed by immunocytochemistry. Compared to healthy PDLs, the periapical lesion samples showed higher Jmjd3 expression. Treatment with GSK-J4 or Jmjd3 siRNA suppressed PDL cells’ osteogenic differentiation by suppressing the expressions of bone-related genes (Runx2, Osterix, and osteocalcin) and mineralization. Jmjd3 knockdown decreased the expressions of cytokines (TNF-α, IL-1β, and IL-6) induced by lipopolysaccharide extracted from Porphyromonas endodontalis (Pe-LPS). Pe-LPS induced the nuclear translocations of Jmjd3 and NF-κB; the latter was inhibited by GSK-J4 treatment. Jmjd3 appears to regulate PDL cells’ osteogenic differentiation and proinflammatory cytokine expressions. en-copyright= kn-copyright= en-aut-name=YuBo en-aut-sei=Yu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangRui en-aut-sei=Wang en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LuoHuikun en-aut-sei=Luo en-aut-mei=Huikun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangDi en-aut-sei=Yang en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangSimo en-aut-sei=Wang en-aut-mei=Simo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YuYaqiong en-aut-sei=Yu en-aut-mei=Yaqiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=QiuLihong en-aut-sei=Qiu en-aut-mei=Lihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=2 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=3 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=4 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=5 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=6 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= en-keyword=periapical lesions kn-keyword=periapical lesions en-keyword=histone demethylase Jmjd3 kn-keyword=histone demethylase Jmjd3 en-keyword=periodontal ligament cell kn-keyword=periodontal ligament cell en-keyword=osteogenic differentiation kn-keyword=osteogenic differentiation en-keyword=proinflammatory cytokines kn-keyword=proinflammatory cytokines END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=255 end-page=263 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intrathecal Administration of the α1 Adrenergic Antagonist Phentolamine Upregulates Spinal GLT-1 and Improves Mirror Image Pain in SNI Model Rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mirror image pain (MIP) is a type of extraterritorial pain that results in contralateral pain or allodynia. Glutamate transporter-1 (GLT-1) is expressed in astrocytes and plays a role in maintaining low glutamate levels in the synaptic cleft. Previous studies have shown that GLT-1 dysfunction induces neuropathic pain. Our previous study revealed bilateral GLT-1 downregulation in the spinal cord of a spared nerve injury (SNI) rat. We hypothesized that spinal GLT-1 is involved in the mechanism of MIP. We also previously demonstrated noradrenergic GLT-1 regulation. Therefore, this study aimed to investigate the effect of an α1 adrenergic antagonist on the development of MIP. Rats were subjected to SNI. Changes in pain behavior and GLT-1 protein levels in the SNI rat spinal cords were then examined by intrathecal administration of the α1 adrenergic antagonist phentolamine, followed by von Frey test and western blotting. SNI resulted in the development of MIP and bilateral downregulation of GLT-1 protein in the rat spinal cord. Intrathecal phentolamine increased contralateral GLT-1 protein levels and partially ameliorated the 50% paw withdrawal threshold in the contralateral hind paw. Spinal GLT-1 upregulation by intrathecal phentolamine ameliorates MIP. GLT-1 plays a role in the development of MIPs. en-copyright= kn-copyright= en-aut-name=NakatsukaKosuke en-aut-sei=Nakatsuka en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuokaYoshikazu en-aut-sei=Matsuoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuritaMasako en-aut-sei=Kurita en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangRuilin en-aut-sei=Wang en-aut-mei=Ruilin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuboiChika en-aut-sei=Tsuboi en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SueNobutaka en-aut-sei=Sue en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KakuRyuji en-aut-sei=Kaku en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Kinoshita Pain Clinic kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=alpha adrenergic receptor kn-keyword=alpha adrenergic receptor en-keyword=glutamate transporter-1 kn-keyword=glutamate transporter-1 en-keyword=mirror image pain kn-keyword=mirror image pain en-keyword=neuropathic pain kn-keyword=neuropathic pain en-keyword=spared nerve injury kn-keyword=spared nerve injury END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=37 article-no= start-page=e202201113 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Indole Editing Enabled by HFIP‐Mediated Ring‐Switch Reactions of 3‐Amino‐2‐Hydroxyindolines en-subtitle= kn-subtitle= en-abstract= kn-abstract=We found the novel reactivity of hemiaminal as a precursor for indole editing at the multi-site. The HFIP-promoted indole editing of indoline hemiaminals affords 2-arylindoles through a ring-switch sequence.

This transformation features mild reaction conditions and good yields with broad functional group tolerance. The utility of this transformation is presented through the one-pot protocol and the synthesis of isocryptolepine. en-copyright= kn-copyright= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashiroToshiki en-aut-sei=Yamashiro en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuKaho en-aut-sei=Shimizu en-aut-mei=Kaho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaDaisuke en-aut-sei=Sawada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=hemiaminals kn-keyword=hemiaminals en-keyword=HFIP kn-keyword=HFIP en-keyword=indoles kn-keyword=indoles en-keyword=molecule editing kn-keyword=molecule editing en-keyword=ring-switch kn-keyword=ring-switch END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=129 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Combination of D-dimer and Glasgow Prognostic Score Can Be Useful in Predicting VTE in Patients with Stage IIIC and IVA Ovarian Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer patients have increased risk of venous thromboembolism (VTE) that must be assessed before treatment. This study aimed to determine effective VTE biomarkers in gynecologic cancer (GC). We investigated the correlation between D-dimer levels, Khorana risk score (KRS), Glasgow prognostic score (GPS), and VTE in 1499 GC patients (583 cervical cancer (CC), 621 endometrial cancer (EC), and 295 ovarian cancer (OC) patients) treated at our institution between January 2008 and December 2019. χ2 and Mann–Whitney U-tests were used to determine statistical significance. We used receiver operating characteristic-curve analysis to evaluate the discriminatory ability of each parameter. D-dimer levels were significantly correlated with KRS and GPS in patients with GC. VTE was diagnosed in 11 CC (1.9%), 27 EC (4.3%), and 39 OC patients (13.2%). Optimal D-dimer cut-off values for VTE were 3.1, 3.2, and 3.9 μg/ml in CC, EC and OC patients, respectively. D-dimer could significantly predict VTE in all GC patients. Furthermore, D-dimer combined with GPS was more accurate in predicting VTE than other VTE biomarkers in stage IIIC and IVA OC (AUC: 0.846; p<0.001). This study demonstrates that combined D-dimer and GPS are useful in predicting VTE in patients with OC. en-copyright= kn-copyright= en-aut-name=KuboKotaro en-aut-sei=Kubo en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKazuhiro en-aut-sei=Okamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HarumaTomoko en-aut-sei=Haruma en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaChikako en-aut-sei=Ogawa en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=D-dimer kn-keyword=D-dimer en-keyword=gynecologic cancer kn-keyword=gynecologic cancer en-keyword=venous thromboembolism kn-keyword=venous thromboembolism END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mouse Model for Optogenetic Genome Engineering en-subtitle= kn-subtitle= en-abstract= kn-abstract=Optogenetics, a technology to manipulate biological phenomena thorough light, has attracted much attention in neuroscience.

The reductive tricarboxylic acid cycle (rTCA) and the Wood-Ljungdahl pathway (WL) have been recognized as the most ancient carbon fixation pathways. The rTCA of the chemolithotrophic Thermosulfidibacter takaii, which was recently demonstrated to take place via an unexpected reverse reaction of citrate synthase, was reproduced using a kinetic network model, and a competition between reductive and oxidative fluxes on rTCA due to an acetyl coenzyme A (ACOA) influx upon acetate uptake was revealed. Avoiding ACOA direct influx into rTCA from WL is, therefore, raised as a kinetically necessary condition to maintain a complete rTCA. This hypothesis was confirmed for deep-branching bacteria and archaea, and explains the kinetic factors governing elementary processes in carbon metabolism evolution from the last universal common ancestor. en-copyright= kn-copyright= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKouji en-aut-sei=Harada en-aut-mei=Kouji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Computer Science and Engineering, Toyohashi University of Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=677 end-page=684 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=EG-VEGF Induces Invasion of a Human Trophoblast Cell Line via PROKR2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Extravillous trophoblast (EVT) invasion is important for embryo implantation, placental development, and successful remodeling of the uterine spiral artery. Endocrine gland derived-vascular endothelial growth factor (EG-VEGF) and matrix metalloproteinases (MMPs) are implicated in EVT invasion; however, the high con-centrations found in pregnancy pathologies have not been investigated in non-tumor trophoblasts. The roles of EG-VEGF, prokineticin receptors (PROKR1/2), MMP-2, and MMP-9 in EVT invasion during spiral artery remodeling were evaluated using human EVT from HTR-8/SVneo cell lines. The expression of MMP-2, MMP-9, and mitogen-activated protein kinase (MAPK), and Akt pathways in HTR-8/SVneo cells treated with recom-binant EG-VEGF alongside anti-PROKR1 and/or anti-PROKR2 antibodies was evaluated using quantitative reverse transcription-PCR and western blotting. Wound-healing and cell invasion assays were performed to assess the migration and invasion of these treated cells. Interestingly, 20 nM EG-VEGF activated ERK1/2 sig-naling and upregulated MMP-2 and MMP-9. This effect was suppressed by anti-PROKR2 antibody via ERK1/2 downregulation. Anti-PROKR2 antibody inhibited the migration and invasion of EG-VEGF-stimulated HTR-8/SVneo cells. Elevated concentrations of EG-VEGF enhance EVT invasion in a human trophoblast cell line by upregulating MMP-2 and MMP-9 via PROKR2. These new insights into the regulation of epithelial cell invasion may help in developing therapeutic interventions for placental-related diseases during pregnancy. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TaniKazumasa kn-aut-sei=Tani kn-aut-mei=Kazumasa aut-affil-num=1 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MishimaSakurako en-aut-sei=Mishima en-aut-mei=Sakurako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhiraAkiko en-aut-sei=Ohira en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayataKei en-aut-sei=Hayata en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=endocrine gland-derived vascular endothelial growth factor kn-keyword=endocrine gland-derived vascular endothelial growth factor en-keyword=prokineticin kn-keyword=prokineticin en-keyword=extravillous trophoblast kn-keyword=extravillous trophoblast en-keyword=matrix metalloproteinase kn-keyword=matrix metalloproteinase en-keyword=obstetric diseases kn-keyword=obstetric diseases END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=671 end-page=675 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multiple Roles of Histidine-Rich Glycoprotein in Vascular Homeostasis and Angiogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Histidine-rich glycoprotein (HRG) is a 75 kDa plasma protein that is synthesized in the liver of many verte-brates and present in their plasma at relatively high concentrations of 100-150 μg/mL. HRG is an abundant and well-characterized protein having a multidomain structure that enable it to interact with many ligands, func-tion as an adaptor molecule, and participate in numerous physiological and pathological processes. As a plasma protein, HRG has been reported to regulate vascular biology, including coagulation, fibrinolysis and angiogenesis, through its binding with several ligands (heparin, FXII, fibrinogen, thrombospondin, and plas-minogen) and interaction with many types of cells (endothelial cells, erythrocytes, neutrophils and platelets). This review aims to summarize the roles of HRG in maintaining vascular homeostasis and regulating angiogen-esis in various pathological conditions. en-copyright= kn-copyright= en-aut-name=GaoShangze en-aut-sei=Gao en-aut-mei=Shangze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=histidine-rich glycoprotein kn-keyword=histidine-rich glycoprotein en-keyword=vascular biology kn-keyword=vascular biology en-keyword=coagulation kn-keyword=coagulation en-keyword=angiogenesis kn-keyword=angiogenesis END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=5 article-no= start-page=549 end-page=556 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Glial Cells as Possible Targets of Neuroprotection through Neurotrophic and Antioxidative Molecules in the Central and Enteric Nervous Systems in Parkinson’s Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson’s disease (PD) is the second most common neurodegenerative disease worldwide. The loss of nigrostriatal dopaminergic neurons produces its characteristic motor symptoms, but PD patients also have non-motor symptoms such as constipation and orthostatic hypotension. The pathological hallmark of PD is the presence of α-synuclein-containing Lewy bodies and neurites in the brain. However, the PD pathology is observed in not only the central nervous system (CNS) but also in parts of the peripheral nervous system such as the enteric nervous system (ENS). Since constipation is a typical prodromal non-motor symptom in PD, often preceding motor symptoms by 10-20 years, it has been hypothesized that PD pathology propagates from the ENS to the CNS via the vagal nerve. Discovery of pharmacological and other methods to halt this progression of neurodegeneration in PD has the potential to improve millions of lives. Astrocytes protect neurons in the CNS by secretion of neurotrophic and antioxidative factors. Similarly, astrocyte-like enteric glial cells (EGCs) are known to secrete neuroprotective factors in the ENS. In this article, we summarize the neuroprotective function of astrocytes and EGCs and discuss therapeutic strategies for the prevention of neurodegeneration in PD targeting neurotrophic and antioxidative molecules in glial cells. en-copyright= kn-copyright= en-aut-name=IsookaNami en-aut-sei=Isooka en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Parkinson’s disease kn-keyword=Parkinson’s disease en-keyword=astrocyte kn-keyword=astrocyte en-keyword=enteric glial cell kn-keyword=enteric glial cell en-keyword=neurotrophic factor kn-keyword=neurotrophic factor en-keyword=antioxidative molecule kn-keyword=antioxidative molecule END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=461 end-page=469 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bendamustine Plus Rituximab as Salvage Treatment for Patients with Relapsed or Refractory Low-grade B-cell Lymphoma and Mantle Cell Lymphoma: A Single-Center Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bendamustine plus rituximab (B-R) is an effective therapy for relapsed or refractory (r/r) low-grade B-cell lymphoma (LGBCL) and mantle cell lymphoma (MCL); however, clinical data from Japanese patients treated with B-R therapy are limited. We retrospectively evaluated the efficacy and safety of B-R therapy in 42 patients who received B-R therapy at our hospital for r/r LGBCL and MCL. All patients received intravenous (IV) ritux-imab 375 mg/m2 on day 1 and IV bendamustine 90 mg/m2 on days 2 and 3 every 28 days for up to 6 cycles. The common histologic subtypes were follicular lymphoma (n = 29, 70%), marginal zone lymphoma (n = 6, 14%), and MCL (n = 5, 12%). The overall response rate was 93%, with 62% complete response and complete response unconfirmed. The median progression-free survival (PFS) was 38 months (95% confidence interval [CI], 24.6 to not reached [NR]), and the median overall survival (OS) was 80 months (95% CI, 60.7 to NR). Patients receiving a cumulative dose of bendamustine ≥ 720 mg/m2 showed a significantly longer PFS and OS. Grade 3/4 adverse events (≥ 10%) included neutropenia (55%), lymphopenia (69%), and nausea (24%). B-R therapy was effective and well tolerated, and the cumulative dose of bendamustine was associated with a favorable outcome. en-copyright= kn-copyright= en-aut-name=MurakamiHiroyuki en-aut-sei=Murakami en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaTakanori en-aut-sei=Yoshioka en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaTakashi en-aut-sei=Moriyama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaTatsunori en-aut-sei=Ishikawa en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakitaMasanori en-aut-sei=Makita en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunamiKazutaka en-aut-sei=Sunami en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=3 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=5 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= en-keyword=bendamustine kn-keyword=bendamustine en-keyword=low grade B-cell lymphoma kn-keyword=low grade B-cell lymphoma en-keyword=mantle cell lymphoma kn-keyword=mantle cell lymphoma END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=363 end-page=372 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of the Transcription Factor BTB and CNC Homology 1 in a Rat Model of Acute Liver Injury Induced by Experimental Endotoxemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hepatic oxidative stress plays an important role in the pathogenesis of several acute liver diseases, and free heme is thought to contribute to endotoxemia-induced acute liver injury. The heme oxygenase 1 (HO-1) gene is upregulated and the δ-aminolevulinate synthase (ALAS1) gene is downregulated in the rat liver following lipopolysaccharide (LPS) treatment. BTB and CNC homology 1 (Bach1) is a heme-responsive transcription factor that normally represses HO-1 expression. In this study, we evaluated the changes in HO-1, ALAS1, and Bach1 expression and nuclear Bach1 expression in rat livers following intravenous LPS administration (10 mg/kg body weight). LPS significantly upregulated HO-1 mRNA and downregulated ALAS1 mRNA in the rat livers, suggesting that hepatic free heme concentrations are increased after LPS treatment. Bach1 mRNA was strongly induced after LPS injection. In contrast, nuclear Bach1 was significantly but transiently decreased after LPS treatment. Rats were also administered hemin (50 mg/kg body weight) intravenously to elevate heme concentrations, which decreased nuclear Bach1 levels. Our results suggest that elevated hepatic free heme may be associated with a decline of nuclear Bach1, and induction of Bach1 mRNA may compensate for the decreased nuclear Bach1 after LPS treatment in the rat liver. en-copyright= kn-copyright= en-aut-name=TaniokaNohito en-aut-sei=Tanioka en-aut-mei=Nohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuHiroko en-aut-sei=Shimizu en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmoriEmiko en-aut-sei=Omori en-aut-mei=Emiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiToru en-aut-sei=Takahashi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaokaMasakazu en-aut-sei=Yamaoka en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Faculty of Health and Welfare Science, Okayama Prefectural University kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=heme oxygenase-1 kn-keyword=heme oxygenase-1 en-keyword=BTB and CNC homology 1 kn-keyword=BTB and CNC homology 1 en-keyword= heme, kn-keyword= heme, en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide en-keyword= liver injury kn-keyword= liver injury END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=299 end-page=306 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interrelationships Between Serum Levels of Procalcitonin and Inflammatory Markers in Patients Who Visited a General Medicine Department en-subtitle= kn-subtitle= en-abstract= kn-abstract=Various laboratory markers of inflammation are utilized in general practice, but their clinical diagnostic significance is often ambiguous. In the present study, we determined the clinical significance of the examination of serum levels of procalcitonin (PCT) by comparing the PCT levels with the levels of other inflammatory markers, based on a retrospective review of 332 PCT-positive patients, including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), connective tissue diseases (8.4%), and non-bacterial infection (7.2%), were analyzed. The serum PCT level was highest in the bacterial infection group (1.94 ng/ml) followed by the non-specific inflammatory group (0.58 ng/ml) and neoplastic diseases group (0.34 ng/ml). The serum PCT level was positively correlated with serum levels of C-reactive protein (rho=0.62), soluble interleukin-2 receptor (sIL-2R; rho=0.69), and ferritin, the plasma level of D-dimer, and white blood cell count, and negatively correlated with the serum albumin level (rho=−0.52), hemoglobin concentration, and platelet count. The serum PCT level showed a stronger positive correlation with the serum sIL-2R level than the other biomarkers. The results suggest that an increased PCT level may indicate not only an infectious state but also a non-bacterial inflammatory condition in the diagnostic process in general practice. en-copyright= kn-copyright= en-aut-name=ArakiJo en-aut-sei=Araki en-aut-mei=Jo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaKosuke en-aut-sei=Oka en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoshimaKoichi en-aut-sei=Itoshima en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bacterial infection kn-keyword=bacterial infection en-keyword=inflammation kn-keyword=inflammation en-keyword=malignant lymphoma kn-keyword=malignant lymphoma en-keyword=procalcitonin kn-keyword=procalcitonin en-keyword=soluble interleukin-2 receptor kn-keyword=soluble interleukin-2 receptor END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=289 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and Safety of Early Intravenous Landiolol on Myocardial Salvage in Patients with ST-segment Elevation Myocardial Infarction before Primary Percutaneous Coronary Intervention: A Randomized Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Early treatment with an oral β-blocker is recommended in patients with a ST-segment–elevation myocardial infarction (STEMI). In this multicenter study, we evaluated the effects of a continuous administration of landiolol, an ultrashort-acting β-blocker, before primary percutaneous coronary intervention (PCI) on myocardial salvage and its safety in STEMI patients. A total of 47 Japanese patients with anterior or lateral STEMI undergoing a primary PCI within 12 h of symptom onset were randomized to receive intravenous landiolol (started at 3 μg/min/kg dose and continued to a total of 50 mg; n=23) or not (control; n=24). Patients with Killip class III or more were excluded. The primary outcome was the myocardial salvage index on cardiac magnetic resonance imaging (MRI) performed 5-7 days after the PCI. Cardiac MRI was performed in 35 patients (74%). The myocardial salvage index in the landiolol group was significantly greater than that in the control group (44.4±14.6% vs. 31.7±18.9%, respectively; p=0.04). There were no significant differences in adverse events at 24 h between the landiolol and control groups. A continuous administration of landiolol before a primary PCI may increase the degree of myocardial salvage without additional hemodynamic adverse effects within the first 24 h after STEMI. en-copyright= kn-copyright= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshikawaMasaki en-aut-sei=Yoshikawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaTakefumi en-aut-sei=Oka en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Cardiology, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=myocardial infarction kn-keyword=myocardial infarction en-keyword=landiolol kn-keyword=landiolol en-keyword= magnetic resonance imaging kn-keyword= magnetic resonance imaging en-keyword=STEMI kn-keyword=STEMI en-keyword=PCI kn-keyword=PCI END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=1 article-no= start-page=134 end-page=142 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of (12R,13S)-pyriculariol and (12R,13S)-dihydropyriculariol revealed that the rice blast fungus, Pyricularia oryzae, produces these phytotoxins as racemates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synthesis of assumed natural (12R,13S)-enantiomers of pyriculariol (1) and dihydropyriculariol (2), phytotoxins isolated from rice blast disease fungus, Pyricularia oryzae, was achieved using Wittig reaction or microwave-assisted Stille coupling reaction as the key step.

The fungus is found to produce optically active phytotoxins when incubated with rotary shaker, but racemic ones when cultured using an aerated jar fermenter. en-copyright= kn-copyright= en-aut-name=NagashimaYuta en-aut-sei=Nagashima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiAyaka en-aut-sei=Sasaki en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraokaRyoya en-aut-sei=Hiraoka en-aut-mei=Ryoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnodaYuko en-aut-sei=Onoda en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaKoji en-aut-sei=Tanaka en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangZi-Yi en-aut-sei=Wang en-aut-mei=Zi-Yi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuwanaAtsuki en-aut-sei=Kuwana en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoYuki en-aut-sei=Sato en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiYuji en-aut-sei=Suzuki en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IzumiMinoru en-aut-sei=Izumi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KuwaharaShigefumi en-aut-sei=Kuwahara en-aut-mei=Shigefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NukinaManabu en-aut-sei=Nukina en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KiyotaHiromasa en-aut-sei=Kiyota en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Laboratory of Applied Bioorganic Chemistry, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=2 en-affil=Laboratory of Applied Bioorganic Chemistry, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Applied Bioorganic Chemistry, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Laboratory of Applied Bioorganic Chemistry, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=9 en-affil=Laboratory of Plant Nutrition and Function, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Laboratory of Applied Bioorganic Chemistry, Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=12 en-affil=Professor Emeritus, Yamagata University kn-affil= affil-num=13 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Pyricularia oryzae kn-keyword=Pyricularia oryzae en-keyword=rice blast disease kn-keyword=rice blast disease en-keyword=structure revision kn-keyword=structure revision en-keyword=total synthesis kn-keyword=total synthesis END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=153 end-page=167 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lactoferrin-like Immunoreactivity in Distinct Neuronal Populations in the Mouse Central Nervous System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lactoferrin (Lf) is an iron-binding glycoprotein mainly found in exocrine secretions and the secondary granules of neutrophils. In the central nervous system (CNS), expression of the Lf protein has been reported in the lesions of some neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis, as well as in the aged brain. Lf is primarily considered an iron chelator, protecting cells from potentially toxic iron or iron-requiring microorganisms. Other biological functions of Lf include immunomodulation and transcriptional regulation. However, the roles of Lf in the CNS have yet to be fully clarified. In this study, we raised an antiserum against mouse Lf and investigated the immunohistochemical localization of Lf-like immunoreactivity (Lf-LI) throughout the CNS of adult mice. Lf-LI was found in some neuronal populations throughout the CNS. Intense labeling was found in neurons in the olfactory systems, hypothalamic nuclei, entorhinal cortex, and a variety of brainstem nuclei. This study provides detailed information on the Lf-LI distribution in the CNS, and the findings should promote further understanding of both the physiological and pathological significance of Lf in the CNS. en-copyright= kn-copyright= en-aut-name=ShimaokaShigeyoshi en-aut-sei=Shimaoka en-aut-mei=Shigeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamaokaHitomi en-aut-sei=Hamaoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueJunji en-aut-sei=Inoue en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TooyamaIkuo en-aut-sei=Tooyama en-aut-mei=Ikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoYoichi en-aut-sei=Kondo en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Anatomy and Cell Biology, Division of Life Sciences, Osaka Medical and Pharmaceutical University kn-affil= affil-num=2 en-affil=Department of Anatomy and Cell Biology, Division of Life Sciences, Osaka Medical and Pharmaceutical University kn-affil= affil-num=3 en-affil=Department of Anatomy and Cell Biology, Division of Life Sciences, Osaka Medical and Pharmaceutical University kn-affil= affil-num=4 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= affil-num=6 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= en-keyword=lactoferrin kn-keyword=lactoferrin en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=brain mapping kn-keyword=brain mapping END start-ver=1.4 cd-journal=joma no-vol=413 cd-vols= no-issue= article-no= start-page=3339 end-page=3347 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210313 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Speciation of chromium in water samples using microfluidic paper-based analytical devices with online oxidation of trivalent chromium en-subtitle= kn-subtitle= en-abstract= kn-abstract= Speciation of chromium (Cr) was demonstrated using microfluidic paper-based analytical devices (μ-PADs) that permit the colorimetric determination of hexavalent chromium (Cr(VI)) and trivalent chromium (Cr(III)) via online oxidation. The μ-PADs consist of left and right channels that allow the simultaneous measurements of Cr(VI) and total Cr based on the colorimetric reaction of Cr(VI) with 1,5-diphenylcarbazide (DPC). For the determination of Cr(VI), a sample solution was directly reacted with DPC in the left channels whereas total Cr was determined in the right channels, which permitted online oxidation in the pretreatment zone containing cerium (IV) (Ce(IV)) followed by a colorimetric reaction with DPC. We found that the online oxidation of Cr(III) proceeded 100% whereas Ce(IV) inhibited the reaction of Cr(VI) with DPC. Therefore, speciation can be achieved by measuring the Cr(VI) and total Cr in the left and right channels followed by the subtraction of Cr(VI) from total Cr. The limits of detection and quantification were 0.008 and 0.02 mg L−1 for Cr(VI) and 0.07 and 0.1 mg L−1 for Cr(III) or total Cr, respectively. The linear dynamic ranges were 0.02–100 mg L−1 and 0.1–60 mg L−1 for Cr(VI) and Cr(III), respectively. The RSDs were less than 7.5%. The results obtained using μ-PADs were in good agreement with those obtained via ICP-OES with recoveries of 92–108% for Cr(III) and 108–110% for Cr (VI) using μ-PADs, and 106–110% for total Cr using ICP-OES. Thus, the μ-PADs could potentially be utilized for the speciation of chromium in developing countries where environmental pollution and the availability of sophisticated instruments are significant problems. en-copyright= kn-copyright= en-aut-name=MuhammedAbdellah en-aut-sei=Muhammed en-aut-mei=Abdellah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HussenAhmed en-aut-sei=Hussen en-aut-mei=Ahmed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=2 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Chromium kn-keyword=Chromium en-keyword=Cr(III) kn-keyword=Cr(III) en-keyword=Cr(VI) kn-keyword=Cr(VI) en-keyword=Online oxidation kn-keyword=Online oxidation en-keyword=Speciation kn-keyword=Speciation END start-ver=1.4 cd-journal=joma no-vol=296 cd-vols= no-issue= article-no= start-page=100524 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Covalent N-arylation by the pollutant 1,2-naphthoquinone activates the EGF receptor en-subtitle= kn-subtitle= en-abstract= kn-abstract=The epidermal growth factor receptor (EGFR) is the most intensively investigated receptor tyrosine kinase. Several EGFR mutations and modifications have been shown to lead to abnormal self-activation, which plays a critical role in carcinogenesis. Environmental air pollutants, which are associated with cancer and respiratory diseases, can also activate EGFR. Specifically, the environmental electrophile 1,2-naphthoquinone (1,2-NQ), a component of diesel exhaust particles and particulate matter more generally, has previously been shown to impact EGFR signaling. However, the detailed mechanism of 1,2-NQ function is unknown. Here, we demonstrate that 1,2-NQ is a novel chemical activator of EGFR but not other EGFR family proteins. We found that 1,2-NQ forms a covalent bond, in a reaction referred to as N-arylation, with Lys80, which is in the ligand-binding domain. This modification activates the EGFR–Akt signaling pathway, which inhibits serum deprivation–induced cell death in a human lung adenocarcinoma cell line. Our study reveals a novel mode of EGFR pathway activation and suggests a link between abnormal EGFR activation and environmental pollutant–associated diseases such as cancer. en-copyright= kn-copyright= en-aut-name=NakaharaKengo en-aut-sei=Nakahara en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaKyohei en-aut-sei=Hamada en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchidaTomoki en-aut-sei=Tsuchida en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbikoYumi en-aut-sei=Abiko en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=6 en-affil=Department of Thoracic, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Thoracic, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=9 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=epidermal growth factor receptor kn-keyword=epidermal growth factor receptor en-keyword=cell signaling kn-keyword=cell signaling en-keyword=chemical modification kn-keyword=chemical modification en-keyword=signal transduction kn-keyword=signal transduction en-keyword=apoptosis kn-keyword=apoptosis END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=9 article-no= start-page=094502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formation of hot ice caused by carbon nanobrushes. II. Dependency on the radius of nanotubes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Stable crystalline structures of confined water can be different from bulk ice. In Paper I [T. Yagasaki et al., J. Chem. Phys. 151, 064702 (2019)] of this study, it was shown, using molecular dynamics (MD) simulations, that a zeolite-like ice structure forms in nanobrushes consisting of (6,6) carbon nanotubes (CNTs) when the CNTs are located in a triangle arrangement. The melting temperature of the zeolite-like ice structure is much higher than the melting temperature of ice Ih when the distance between the surfaces of CNTs is ∼0.94 nm, which is the best spacing for the bilayer structure of water. In this paper, we perform MD simulations of nanobrushes of CNTs that are different from (6,6) CNTs in radius. Several new porous ice structures form spontaneously in the MD simulations. A stable porous ice forms when the radius of its cavities matches the radius of the CNTs well. All cylindrical porous ice structures found in this study can be decomposed into a small number of structural blocks. We provide a new protocol to classify cylindrical porous ice crystals on the basis of this decomposition. en-copyright= kn-copyright= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=557 end-page=562 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Japanese Patient with Gastric Cancer and Dihydropyrimidine Dehydrogenase Deficiency Presenting with DPYD Variants en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 63-year-old Japanese male with stomach adenocarcinoma received oral 5-fluorouracil derivative, cisplatin and trastuzumab chemotherapy.

Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that the BAP/ALP ratios of the patients with fever and those with inflammatory diseases were significantly lower than the ratios of other patient groups. The BAP/ALP ratios of the patients with osteoporosis and those with metabolic bone diseases were higher than those of the patients with other conditions. The BAP/ALP ratio was found to be negatively correlated with age, a cor-relation that has not been found in other ethnicities. The serum BAP/ALP ratio was inversely correlated with serum CRP levels but was positively correlated with serum albumin levels and hemoglobin concentrations. Collectively, our results suggest that the BAP/ALP ratio could be a useful predictor for important geriatric con-ditions seen in general practice. en-copyright= kn-copyright= en-aut-name=YokotaYuya en-aut-sei=Yokota en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AndoAkemi en-aut-sei=Ando en-aut-mei=Akemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=alkaline phosphatase kn-keyword=alkaline phosphatase en-keyword=BAP kn-keyword=BAP en-keyword=CRP kn-keyword=CRP en-keyword=inflammation kn-keyword=inflammation en-keyword=osteoporosis kn-keyword=osteoporosis END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=5 article-no= start-page=381 end-page=389 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Relevance of Serum Prolactin Levels to Inflammatory Reaction in Male Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=−0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status. en-copyright= kn-copyright= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoshimaKoichi en-aut-sei=Itoshima en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hormones kn-keyword=hormones en-keyword=hyperprolactinemia kn-keyword=hyperprolactinemia en-keyword=inflammation kn-keyword=inflammation en-keyword=pituitary kn-keyword=pituitary en-keyword=prolactin kn-keyword=prolactin END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue=11 article-no= start-page=114501 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure and phase behavior of high-density ice from molecular-dynamics simulations with the ReaxFF potential en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a molecular dynamics simulation study of dense ice modeled by the reactive force field (ReaxFF) potential, focusing on the possibility of phase changes between crystalline and plastic phases as observed in earlier simulation studies with rigid water models. It is demonstrated that the present model system exhibits phase transitions, or crossovers, among ice VII and two plastic ices with face-centered cubic (fcc) and body-centered cubic (bcc) lattice structures. The phase diagram derived from the ReaxFF potential is different from those of the rigid water models in that the bcc plastic phase lies on the high-pressure side of ice VII and does the fcc plastic phase on the low-pressure side of ice VII. The phase boundary between the fcc and bcc plastic phases on the pressure, temperature plane extends to the high-temperature region from the triple point of ice VII, fcc plastic, and bcc plastic phases. Proton hopping, i.e., delocalization of a proton, along between two neighboring oxygen atoms in dense ice is observed for the ReaxFF potential but only at pressures and temperatures both much higher than those at which ice VII–plastic ice transitions are observed. en-copyright= kn-copyright= en-aut-name=AdachiYuji en-aut-sei=Adachi en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Sciences, Okayama University kn-affil= affil-num=2 en-affil=2Department of Chemistry, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=365 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Vancomycin Dose Adjustment in a Sepsis patient with Bacterial Meningitis Using Cystatin C en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cystatin C-guided vancomycin (VCM) dosing is useful in critically ill patients. Its usefulness in septic patients with bacterial meningitis remains unknown, as there are no published reports. In this study, we sought to clarify its benefit. Cystatin C was used to guide VCM dosing in a septic bacterial meningitis patient with normal kidney function, according to therapeutic drug monitoring (TDM). Using cystatin C, the Bayesian method-based TDM made optimal VCM dosing possible, and decreased the predicted error (4.85 mg/L) compared to serum creatinine (16.83 mg/L). We concluded TDM of VCM using cystatin C can be considered in sepsis patients with bacterial meningitis with normal kidney function. en-copyright= kn-copyright= en-aut-name=ChumaMasayuki en-aut-sei=Chuma en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoMasateru en-aut-sei=Kondo en-aut-mei=Masateru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakechiKenshi en-aut-sei=Takechi en-aut-mei=Kenshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaNaoto en-aut-sei=Okada en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShibataAkitomo en-aut-sei=Shibata en-aut-mei=Akitomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AsadaMizuho en-aut-sei=Asada en-aut-mei=Mizuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtoJun en-aut-sei=Oto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YanagawaHiroaki en-aut-sei=Yanagawa en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=2 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=4 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Saiseikai Kumamoto Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Medical Hospital, Tokyo Medical and Dental University kn-affil= affil-num=9 en-affil=Department of Emergency and Critical Care Medicine, Tokushima University Graduate School of Biomedical Sciences kn-affil= affil-num=10 en-affil=Clinical Research Center for Developmental Therapeutics, Tokushima University Hospital kn-affil= affil-num=11 en-affil=Department of Pharmacy, Tokushima University Hospital kn-affil= en-keyword=vancomycin, kn-keyword=vancomycin, en-keyword=therapeutic drug monitoring kn-keyword=therapeutic drug monitoring en-keyword=cystatin C kn-keyword=cystatin C en-keyword=bacterial meningitis kn-keyword=bacterial meningitis en-keyword=sepsis kn-keyword=sepsis END start-ver=1.4 cd-journal=joma no-vol=220 cd-vols= no-issue=9 article-no= start-page=1900021 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rapid Synthesis of Poly(methyl methacrylate) Particles with High Molecular Weight by Soap‐Free Emulsion Polymerization Using Water‐in‐Oil Slug Flow en-subtitle= kn-subtitle= en-abstract= kn-abstract= flow process for the production of poly(methyl methacrylate) (PMMA) particles is proposed by soap‐free emulsion polymerization using a water‐in‐oil (W/O) slug flow in a microreactor. Thin oil films generated around the dispersed aqueous phase of the W/O slug prevent the prepared particles from adhesion to the microchannel wall, enabling the continuous production of PMMA particles without clogging. The effects of the linear flow rate of the slug flow and the addition of ethanol in the dispersed aqueous phase on the polymerization are evaluated. It is found that increasing the linear flow rate of the slug flow or the addition of ethanol in the dispersed aqueous phase results in PMMA particles with high molecular weight (≈1500 kg mol−1) in 20 min reaction time. It is believed that this process would be a promising way to prepare polymer particles with high molecular weight in a short reaction time. en-copyright= kn-copyright= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KaritaKengo en-aut-sei=Karita en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TawaraKoki en-aut-sei=Tawara en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SogaTakuya en-aut-sei=Soga en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Material and Energy Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=heterogeneous polymerization kn-keyword=heterogeneous polymerization en-keyword=internal circulation kn-keyword=internal circulation en-keyword=microreactors kn-keyword=microreactors en-keyword=microspheres kn-keyword=microspheres END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=66 article-no= start-page=15189 end-page=15197 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190918 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mechanistic Insights into Rhenium-Catalyzed Regioselective C-Alkenylation of Phenols with Internal Alkynes en-subtitle= kn-subtitle= en-abstract= kn-abstract= A (μ-aryloxo)rhenium complex was isolated and confirmed as a key precatalyst for rhenium-catalyzed ortho-alkenylation (C-alkenylation) of unprotected phenols with alkynes. The reaction exclusively provided ortho-alkenylphenols; the formation of para or multiply alkenylated phenols and hydrophenoxylation (O-alkenylation) products was not observed. Several mechanistic experiments excluded a classical Friedel-Crafts-type mechanism, leading to the proposed phenolic hydroxyl group assisted electrophilic alkenylation as the most plausible reaction mechanism. For this purpose, the use of rhenium, a metal between the early and late transition metals in the periodic table, was key for the activation of both the soft carbon-carbon triple bond of the alkyne and the hard oxygen atom of the phenol, at the same time. ortho-Selective alkenylation with allenes also provided the corresponding adducts with a substitution pattern different from that obtained by the addition reaction with alkynes. en-copyright= kn-copyright= en-aut-name=MuraiMasahito en-aut-sei=Murai en-aut-mei=Masahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoMasaki en-aut-sei=Yamamoto en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaiKazuhiko en-aut-sei=Takai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=alkenylation kn-keyword=alkenylation en-keyword=homogeneous catalysis kn-keyword=homogeneous catalysis en-keyword=reaction mechanisms kn-keyword=reaction mechanisms en-keyword=regioselectivity kn-keyword=regioselectivity en-keyword=rhenium kn-keyword=rhenium END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=2 article-no= start-page=798 end-page=805 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formal Total Synthesis of Manzacidin B via Sequential Diastereodivergent Henry Reaction en-subtitle= kn-subtitle= en-abstract= kn-abstract=A formal total synthesis of manzacidin B is described. beta,beta-Disubstituted gamma-hydroxy-beta-aminoalcohol, the key structure of manzacidin B, is stereoselectively constructed via sequential Henry reactions.

However, iron overload is known to induce carcinogenesis via oxidative stress. Cancer cells require large amounts of iron for their rapid division and cell growth. Iron was recently found to play a role in cancer stem cells (CSCs); it maintains stemness during development. Iron also plays an important role in stemness by moderating reactive oxygen species. Thus, iron metabolism in CSCs is a promising therapeutic target. In this review, we summarize the roles of iron in cancer cells and CSCs. We also summarize anti-cancer therapeutic studies with iron chelators and describe our expectation of a new therapeutic strategy for CSCs on the basis of our findings. en-copyright= kn-copyright= en-aut-name=ChenYuehua en-aut-sei=Chen en-aut-mei=Yuehua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=XingBoyi en-aut-sei=Xing en-aut-mei=Boyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=QiJiping en-aut-sei=Qi en-aut-mei=Jiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, the First Affiliated Hospital of Harbin Medical University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cancer stem cell kn-keyword=cancer stem cell en-keyword=stemness kn-keyword=stemness en-keyword=iron kn-keyword=iron en-keyword=chelation kn-keyword=chelation en-keyword=chemotherapy kn-keyword=chemotherapy END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=23 article-no= start-page=15373 end-page=15379 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Copper-Catalyzed Regioselective Aminothiolation of Aromatic and Aliphatic Alkenes with N-Fluorobenzenesulfonimide and Thiols through Three-Component Radical Coupling en-subtitle= kn-subtitle= en-abstract= kn-abstract= Copper-catalyzed regioselective aminothiolation of terminal and internal alkenes with N-fluorobenzenesulfonimide and thiols has been developed.

However, current screening methods for rexinoids are slow and require special apparatus or facilities. Here, we created 7-hydroxy-2-oxo-6-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-2H-chromene-3-carboxylic acid (10, CU-6PMN) as a new fluorescent RXR agonist and developed a screening system of rexinoids using 10. Compound 10 was designed based on the fact that umbelliferone emits strong fluorescence in a hydrophilic environment, but the fluorescence intensity decreases in hydrophobic environments such as the interior of proteins. The developed assay using 10 enabled screening of rexinoids to be performed easily within a few hours by monitoring changes of fluorescence intensity with widely available fluorescence microplate readers, without the need for processes such as filtration. en-copyright= kn-copyright= en-aut-name=YamadaShoya en-aut-sei=Yamada en-aut-mei=Shoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiMayu en-aut-sei=Kawasaki en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiharaMichiko en-aut-sei=Fujihara en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMasaki en-aut-sei=Watanabe en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakamuraYuta en-aut-sei=Takamura en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakiokuMaho en-aut-sei=Takioku en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiokaHiromi en-aut-sei=Nishioka en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiYasuo en-aut-sei=Takeuchi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MakishimaMakoto en-aut-sei=Makishima en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MotoyamaTomoharu en-aut-sei=Motoyama en-aut-mei=Tomoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoSohei en-aut-sei=Ito en-aut-mei=Sohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TokiwaHiroaki en-aut-sei=Tokiwa en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakanoShogo en-aut-sei=Nakano en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KakutaHiroki en-aut-sei=Kakuta en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Division of Biochemistry, Department of Biomedical Sciences, Nihon University School of Medicine kn-affil= affil-num=10 en-affil=Graduate School of Integrated Pharmaceutical and Nutritional Sciences, University of Shizuoka kn-affil= affil-num=11 en-affil=Graduate School of Integrated Pharmaceutical and Nutritional Sciences, University of Shizuoka kn-affil= affil-num=12 en-affil=Department of Chemistry and Research Center of Smart Molecules, Rikkyo University kn-affil= affil-num=13 en-affil=Graduate School of Integrated Pharmaceutical and Nutritional Sciences, University of Shizuoka kn-affil= affil-num=14 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=144 cd-vols= no-issue=22 article-no= start-page=224104 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A reference-modified density functional theory: An application to solvation free-energy calculations for a Lennard-Jones solution en-subtitle= kn-subtitle= en-abstract= kn-abstract= In the conventional classical density functional theory (DFT) for simple fluids, an ideal gas is usually chosen as the reference system because there is a one-to-one correspondence between the external field and the density distribution function, and the exact intrinsic free-energy functional is available for the ideal gas. In this case, the second-order density functional Taylor series expansion of the excess intrinsic free-energy functional provides the hypernetted-chain (HNC) approximation. Recently, it has been shown that the HNC approximation significantly overestimates the solvation free energy (SFE) for an infinitely dilute Lennard-Jones (LJ) solution, especially when the solute particles are several times larger than the solvent particles [T. Miyata and J. Thapa, Chem. Phys. Lett. 604, 122 (2014)]. In the present study, we propose a reference-modified density functional theory as a systematic approach to improve the SFE functional as well as the pair distribution functions. The second-order density functional Taylor series expansion for the excess part of the intrinsic free-energy functional in which a hard-sphere fluid is introduced as the reference system instead of an ideal gas is applied to the LJ pure and infinitely dilute solution systems and is proved to remarkably improve the drawbacks of the HNC approximation. Furthermore, the third-order density functional expansion approximation in which a factorization approximation is applied to the triplet direct correlation function is examined for the LJ systems. We also show that the third-order contribution can yield further refinements for both the pair distribution function and the excess chemical potential for the pure LJ liquids. en-copyright= kn-copyright= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaruyamaYutaka en-aut-sei=Maruyama en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsutakeAyori en-aut-sei=Mitsutake en-aut-mei=Ayori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Co-Design Team, Exascale Computing Project, RIKEN Advanced Institute for Computational Science kn-affil= affil-num=3 en-affil=Co-Design Team, Exascale Computing Project, RIKEN Advanced Institute for Computational Science kn-affil= affil-num=4 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=46 article-no= start-page=25492 end-page=25497 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141017 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Model-potential-free analysis of small angle scattering of proteins in solution: insights into solvent effects on protein-protein interaction en-subtitle= kn-subtitle= en-abstract= kn-abstract= To extract protein-protein interaction from experimental small-angle scattering of proteins in solutions using liquid state theory, a model potential consisting of a hard-sphere repulsive potential and the excess interaction potential has been introduced. In the present study, we propose a model-potential-free integral equation method that extracts the excess interaction potential by using the experimental small-angle scattering data without specific model potential such as the Derjaguin-Landau-Verwey-Overbeek (DLVO)-type model. Our analysis of experimental small-angle X-ray scattering data for lysozyme solution shows both the stabilization of contact configurations of protein molecules and a large activation barrier against the formation of the contact configurations in addition to the screened Coulomb repulsion. These characteristic features, which are not well-described by the DLVO-type model, are interpreted as solvent effects. en-copyright= kn-copyright= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImamuraHiroshi en-aut-sei=Imamura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaTakeshi en-aut-sei=Morita en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsogaiYasuhiro en-aut-sei=Isogai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishikawaKeiko en-aut-sei=Nishikawa en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Advanced Integration Science, Chiba University kn-affil= affil-num=3 en-affil=Graduate School of Advanced Integration Science, Chiba University kn-affil= affil-num=4 en-affil=Department of Biotechnology, Toyama Prefectural University kn-affil= affil-num=5 en-affil=Graduate School of Advanced Integration Science, Chiba University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=26 article-no= start-page=2009 end-page=2011 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Erratum: "A solvation-free-energy functional: A reference-modified density functional formulation" [J.

Many hypotheses have been suggested especially about the relationship between HMGB1 and inflammation responses and blood-brain barrier disruption during epileptogenesis. In this review, we will mainly discuss the role of HMGB1 in epileptogenesis. en-copyright= kn-copyright= en-aut-name=FuLi en-aut-sei=Fu en-aut-mei=Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=HMGB1 kn-keyword=HMGB1 en-keyword=epileptogenesis kn-keyword=epileptogenesis en-keyword=inflammation kn-keyword=inflammation en-keyword=blood-brain barrier kn-keyword=blood-brain barrier END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=5 article-no= start-page=379 end-page=382 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histidine-rich Glycoprotein Modulates the Blood-vascular System in Septic Condition en-subtitle= kn-subtitle= en-abstract= kn-abstract= Histidine-rich glycoprotein (HRG) is a 75 kDa glycoprotein synthesized in the liver whose plasma concentration is 100-150 μg/ml. HRG has been shown to modulate sepsis-related biological reactions by binding to several substances and cells, including heparin, factor XII, fibrinogen, thrombospondin, plasminogen, C1q, IgG, heme, LPS, dead cells, bacteria, and fungi. Therefore, reduction of plasma HRG levels in sepsis leads to dysregulation of coagulation, fibrinolysis, and immune response, resulting in disseminated intravascular coagulation and multiple organ failure. This review summarizes the binding and functional properties of HRG in sepsis. en-copyright= kn-copyright= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=htidine-rich glycoprotein kn-keyword=htidine-rich glycoprotein en-keyword=septic pathogenesis kn-keyword=septic pathogenesis en-keyword=immunothrombosis kn-keyword=immunothrombosis END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=315 end-page=323 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Construction and Characterization of a PGN_0297 Mutant of Porphyromonas gingivalis: Evidence of the Contribution of PGN_0297 to Gingipain Activity en-subtitle= kn-subtitle= en-abstract= kn-abstract=The periodontal pathogen Porphyromonas gingivalis shows colonial pigmentation on blood agar and produces gingipains (Kgp, RgpA, and RgpB), cysteine proteases involved in an organism’s virulence and pigmentation. We showed previously that deletion of the PGN_0300 gene abolished the pigmentation activity and reduced the proteolytic activity of gingipains. The role of the PGN_0297 gene, which consists of an operon with the PGN_0300 gene, is unclear. Herein we examined the effect of PGN_0297 gene deletion on the pigmentation and proteolytic activities and transcriptional levels of gingipains. A PGN_0297 gene deletion mutant (ΔPGN_0297) did not exhibit the pigmentation. The proteolytic activity of the gingipains was decreased in the culture supernatant and on the cell surface of ΔPGN_0297. The mutant ΔPGN_0297 failed to attenuate Akt phosphorylation at Thr308 and Ser473, but both phosphorylations were attenuated in the wild-type and its complementation strain. The deletion of PGN_0297 gene did not substantially affect the transcriptional levels of the gingipain genes kgp, rgpA, and rgpB. Taken together, these results indicate that PGN_0297 is closely involved in the secretion and maturation of gingipains. en-copyright= kn-copyright= en-aut-name=OnoShintaro en-aut-sei=Ono en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakayamaMasaaki en-aut-sei=Nakayama en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TachibanaMasato en-aut-sei=Tachibana en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Abu Saleh Muhammad Shahriar en-aut-sei=Abu Saleh Muhammad Shahriar en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HelingWang en-aut-sei=Heling en-aut-mei=Wang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=periodontitis kn-keyword=periodontitis en-keyword=Porphyromonas gingivalis kn-keyword=Porphyromonas gingivalis en-keyword=gingipain kn-keyword=gingipain en-keyword=C-terminal domain kn-keyword=C-terminal domain en-keyword=secretion system kn-keyword=secretion system END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=285 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic Reorganization of Microtubule and Glioma Invasion en-subtitle= kn-subtitle= en-abstract= kn-abstract= Gliomas are characterized as highly diffuse infiltrating tumors, and currently available treatments such as surgery, radiation and chemotherapy are unfeasible or show limited efficacy against these tumors. Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, The University of Texas Health Science Center at Houston kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=cytoskeletons kn-keyword=cytoskeletons en-keyword=invasion kn-keyword=invasion en-keyword=microtubules kn-keyword=microtubules END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=255 end-page=262 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improvement of Open Bite and Stomatognathic Function in an Axenfeld- Rieger Syndrome Patient by Orthodontic Sectional Arch Mechanics: Clinical Considerations and the Risk of Orthodontic Tooth Movement en-subtitle= kn-subtitle= en-abstract= kn-abstract= Orthodontists need to understand the orthodontic risks associated with systemic disorders. Axenfeld-Rieger syndrome (ARS) is a rare autosomal dominant disorder with genetic and morphological variability. The risks of orthodontic treatment in ARS patients have been unclear.

An undesirable development of external apical root resorption (EARR) was observed in all intrusive force-applied posterior teeth during the patient’s orthodontic treatment, suggesting that ARS patients have a higher risk of EARR than the general population. en-copyright= kn-copyright= en-aut-name=SekiDaisuke en-aut-sei=Seki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeshitaNobuo en-aut-sei=Takeshita en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SeiryuMasahiro en-aut-sei=Seiryu en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DeguchiToru en-aut-sei=Deguchi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Takano-YamamotoTeruko en-aut-sei=Takano-Yamamoto en-aut-mei=Teruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Orthodontics and Dentofacial Orthopedics, Tohoku University Graduate School of Dentistry kn-affil= affil-num=2 en-affil=Division of Orthodontics and Dentofacial Orthopedics, Tohoku University Graduate School of Dentistry kn-affil= affil-num=3 en-affil=Division of Orthodontics and Dentofacial Orthopedics, Tohoku University Graduate School of Dentistry kn-affil= affil-num=4 en-affil=Division of Orthodontics, The Ohio State University College of Dentistry kn-affil= affil-num=5 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= en-keyword=Axenfeld-Rieger syndrome kn-keyword=Axenfeld-Rieger syndrome en-keyword=external apical root resorption kn-keyword=external apical root resorption en-keyword=miniscrew implant kn-keyword=miniscrew implant en-keyword=anterior open bite kn-keyword=anterior open bite END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=213 end-page=221 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spiral Trajectory Modulation of Rheotaxic Motile Human Sperm in Cylindrical Microfluidic Channels of Different Inner Diameters en-subtitle= kn-subtitle= en-abstract= kn-abstract= We investigated the relationship between human sperm rheotaxis and motile sperm trajectories by using poly-(dimethylsiloxane) (PDMS)-based cylindrical microfluidic channels with inner diameters of 100 μm, 50 μm, and 70 μm, which corresponded to the inner diameter of the human isthmus, the length of a sperm and a diameter intermediate between the two, respectively. We counted the number of rheotaxic sperm and sperm with spiral motion. We also analyzed motile sperm trajectories. As the cylindrical channel diameter was decreased, the percentage of sperm cells exhibiting rheotaxis, the percentage of sperm cells exhibiting spiral motion, the frequency-to-diameter ratio of the sperm cells’ spiral trajectories, and the surface area of the microfluidic channel increased, while the flagellar motion at the channel wall decreased. The percentage of sperm exhibiting a spiral trajectory and the frequency-to-diameter ratio of the sperm cells’ spiral trajectories were thus affected by the channel diameter. Our findings suggest that the oviduct structure affects the swimming properties of sperm cells, guiding them from the uterus to the ampulla for egg fertilization. These results could contribute to the development of motile sperm-sorting microfluidic devices for assisted reproductive technologies. en-copyright= kn-copyright= en-aut-name=NishinaSaori en-aut-sei=Nishina en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraKoji en-aut-sei=Matsuura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Cardiovascular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biomedical Engineering, Faculty of Engineering, Okayama University of Science kn-affil= affil-num=3 en-affil=Cardiovascular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sperm motility kn-keyword=sperm motility en-keyword=trajectory kn-keyword=trajectory en-keyword=microfluidic channel kn-keyword=microfluidic channel en-keyword=rheotaxis kn-keyword=rheotaxis en-keyword=oviduct structure kn-keyword=oviduct structure END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=2 article-no= start-page=135 end-page=146 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen XVIII Deposition in the Basement Membrane Zone beneath the Newly Forming Epidermis during Wound Healing in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract= The basement membrane (BM) is composed of various extracellular molecules and regulates tissue regeneration and maintenance.

Immunohistochemistry demonstrated that collagen XVIII was deposited in the BM zone beneath newly forming epidermis in day 3 and 6 wounds. Laminin-332, known to be the earliest BM component appearing in wounds, was colocalized with collagen XVIII in the epidermal BM zone at days 3 and 6. The deposition of α1(IV) collagen and nidogen-1 in the epidermal BM zone occurred later than that of collagen XVIII. We also observed the short isoform of collagen XVIII in the epidermal BM zone at day 3 post-wounding. Collectively, our results suggested that collagen XVIII plays a role in the formation of the dermal-epidermal junction during re-epithelialization, and that it is the short isoform that is involved in the early phase of re-epithelialization. en-copyright= kn-copyright= en-aut-name=MaebaTakahiro en-aut-sei=Maeba en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YonezawaTomoko en-aut-sei=Yonezawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomonoYasuko en-aut-sei=Tomono en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HeljasvaaraRitva en-aut-sei=Heljasvaara en-aut-mei=Ritva kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PihlajaniemiTaina en-aut-sei=Pihlajaniemi en-aut-mei=Taina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InagawaKiichi en-aut-sei=Inagawa en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Shigei Medical Research Institute kn-affil= affil-num=5 en-affil=Center for Cancer Biomarkers CCBIO, Department of Biomedicine, University of Bergen kn-affil= affil-num=6 en-affil=Oulu Center for Cell-Matrix Research, Biocenter Oulu, Faculty of Biochemistry and Molecular Medicine, University of Oulu kn-affil= affil-num=7 en-affil=Department of Plastic and Reconstructive Surgery, Kawasaki Medical School, Kurashiki kn-affil= affil-num=8 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=collagen XVIII kn-keyword=collagen XVIII en-keyword=basement membrane kn-keyword=basement membrane en-keyword=wound healing kn-keyword=wound healing en-keyword=re-epithelialization kn-keyword=re-epithelialization en-keyword=skin kn-keyword=skin END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of Kallikrein-Related Peptidases in Atopic Dermatitis en-subtitle= kn-subtitle= en-abstract= kn-abstract= Excessive protease activity is a characteristic abnormality that affects the epidermal barrier in patients with atopic dermatitis (AD). Kallikrein-related peptidases (KLKs) are excessively expressed in AD lesions, and it is suggested that the abnormal action of KLKs is involved in the skin barrier dysfunction in AD. In other words, overexpressed KLKs disrupt the normal barrier function, and due to that breakdown, external substances that can become antigens of AD easily invade the epidermis, resulting in dermatitis, coupled with the induction of Th2 cytokines. Further investigations are required to elucidate the role of KLKs in AD; this knowledge could contribute to the design of new therapeutic and prophylactic drugs for AD. en-copyright= kn-copyright= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=atopic dermatitis kn-keyword=atopic dermatitis en-keyword=kallikrein-related peptidases kn-keyword=kallikrein-related peptidases en-keyword=epidermal barrier dysfunction kn-keyword=epidermal barrier dysfunction END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=6 article-no= start-page=1984 end-page=1996 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stereodivergent Synthesis and Stereochemical Reassignment of the C79-C104 Fragment of Symbiodinolide en-subtitle= kn-subtitle= en-abstract= kn-abstract= We have synthesized eight possible diastereoisomers 3 a-h of the C79-C97 fragment of symbiodinolide (1) in a stereodivergent manner by utilizing a dithiane addition to the aldehyde as a key step.

By combining the stereostructural outcomes of the C79-C97 and C94-C104 fragments, we have proposed four candidate compounds of the C79-C104 fragment 2 a-d.

Glycosylation of 16 with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose (18) in the presence of tin(IV) chloride yielded the corresponding beta-D-ribofuranoside.

L-carnitine is known to shuttle free fatty acids (FFAs) from the cytosol into mitochondria matrix for -oxidation and energy production, and in a previous study we found that treatment with L-carnitine suppresses 3, 3', 5-triiodothyronine (T3) and FFA-induced MPT by reducing the level of FFAs. In the present study we focus on acetyl-L-carnitine, which is also involved in fatty acid oxidation, to determine its effect on T3-induced tail regression in Rana rugosa tadpoles and spontaneous tail regression in Xenopus laevis tadpoles. The ladder-like DNA profile and increases in caspase-3 and caspase-9 indicative of apoptosis in the tails of T3-treated tadpoles were found to be suppressed by the addition of acetyl-L-carnitine. Likewise, acetyl-L-carnitine was found to inhibit thyroid hormone regulated spontaneous metamorphosis in X. laevis tadpoles, accompanied by decreases in caspase and phospholipase A2 activity, as well as non-ladder-like DNA profiles. These findings support our previous conclusion that elevated levels of FFAs initiate MPT and activate the signaling pathway controlling apoptotic cell death in tadpole tails during anuran metamorphosis. en-copyright= kn-copyright= en-aut-name=HanadaHideki en-aut-sei=Hanada en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobuchiHirotsugu en-aut-sei=Kobuchi en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoMasanao en-aut-sei=Yamamoto en-aut-mei=Masanao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KashiwagiKeiko en-aut-sei=Kashiwagi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuKenjiro en-aut-sei=Katsu en-aut-mei=Kenjiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UtsumiToshihiko en-aut-sei=Utsumi en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KashiwagiAkihiko en-aut-sei=Kashiwagi en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiJunzo en-aut-sei=Sasaki en-aut-mei=Junzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InoueMasayasu en-aut-sei=Inoue en-aut-mei=Masayasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UtsumiKozo en-aut-sei=Utsumi en-aut-mei=Kozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Hiroshima Univ, Inst Amphibian Biol, Grad Sch Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Cell Chem, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Okayama Univ, Dept Cytol & Histol, Grad Sch Med Dent & Pharmaceut Sci affil-num=4 en-affil= kn-affil=Hiroshima Univ, Inst Amphibian Biol, Grad Sch Sci affil-num=5 en-affil= kn-affil=Kumamoto Univ, Div Pattern Format, Dept Organogenesis, Inst Mol Embryol & Genet affil-num=6 en-affil= kn-affil=Yamaguchi Univ, Grad Sch Med affil-num=7 en-affil= kn-affil=Hiroshima Univ, Inst Amphibian Biol, Grad Sch Sci affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Cytol & Histol, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Osaka City Univ, Sch Med, Dept Biochem & Mol Pathol affil-num=10 en-affil= kn-affil=Okayama Univ, Dept Cytol & Histol, Grad Sch Med Dent & Pharmaceut Sci END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=2 article-no= start-page=95 end-page=98 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2013 Incentive Award of the Okayama Medical Association in Cardiovascular and Pulmonary Research (2013 Sunada Prize) kn-title=平成25年度岡山医学会賞 胸部・循環研究奨励賞（砂田賞） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NakatsukaAtsuko en-aut-sei=Nakatsuka en-aut-mei=Atsuko kn-aut-name=中司敦子 kn-aut-sei=中司 kn-aut-mei=敦子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院　腎臓・糖尿病・内分泌内科 END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=2 article-no= start-page=89 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2013 Incentive Award of the Okayama Medical Association in Cancer Research (2013 Hayashibara Prize and Yamada Prize) kn-title=平成25年度岡山医学会賞 がん研究奨励賞（林原賞・山田賞） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name=長谷井嬢 kn-aut-sei=長谷井 kn-aut-mei=嬢 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　整形外科学 END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue= article-no= start-page=240 end-page=245 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Speciation of arsenic in a thermoacidophilic iron-oxidizing archaeon, Acidianus brierleyi, and its culture medium by inductively coupled plasma–optical emission spectroscopy combined with flow injection pretreatment using an anion-exchange mini-column en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thermoacidophilic iron-oxidizing archaeon Acidianus brierleyi is a microorganism that could be useful in the removal of inorganic As from wastewater, because it simultaneously oxidizes As(III) and Fe(II) to As(V) and Fe(III) in an acidic culture medium, resulting in the immobilization of As(V) as FeAsO4. To investigate the oxidation mechanism, speciation of the As species in both the cells and its culture media is an important issue. Here we describe the successive determination of As(III), As(V), and total As in A. brierleyi and its culture medium via a facile method based on inductively coupled plasma–optical emission spectroscopy (ICP–OES) with a flow injection pretreatment system using a mini-column packed with an anion-exchange resin. The flow-injection pretreatment system consisted of a syringe pump, a selection valve, and a switching valve, which were controlled by a personal computer. Sample solutions with the pH adjusted to 5 were flowed into the mini-column to retain the anionic As(V), whereas As(III) was introduced into ICP–OES with no adsorption on the mini-column due to its electrically neutral form. An acidic solution (1 M HNO3) was then flowed into the mini-column to elute As(V) followed by ICP–OES measurement. The same sample was also subjected to ICP–OES without being passed through the mini-column in order to determine the total amounts of As(III) and As(V). The method was verified by comparing the results of the total As with the sum of As(III) and As(V). The calibration curves showed good linearity with limits of detection of 158, 86, and 211 ppb for As(III), As(V), and total As, respectively. The method was successfully applicable to the determination of the As species contained in the pellets of A. brierleyi and their culture media. The results suggested that the oxidation of As(III) was influenced by the presence of Fe(II) in the culture medium, i.e., Fe(II) enhanced the oxidation of As(III) in A. brierleyi. In addition, we found that no soluble As species was contained in the cell pellets and more than 60% of the As(III) in the culture medium was oxidized by A. brierleyi after a 6-day incubation.

We studied the expression of proteins that possibly affect ALA-mediated PpIX accumulation, namely oligopeptide transporter-1 and -2, ferrochelatase and ATP-binding cassette transporter G2 (ABCG2), in several tumor cell lines. Among these proteins, only ABCG2 correlated negatively with ALA-mediated PpIX accumulation. Both a subcellular fractionation study and confocal laser microscopic analysis revealed that ABCG2 was distributed not only in the plasma membrane but also intracellular organelles, including mitochondria. In addition, mitochondrial ABCG2 regulated the content of ALA-mediated PpIX in mitochondria, and Ko143, a specific inhibitor of ABCG2, enhanced mitochondrial PpIX accumulation. To clarify the possible roles of mitochondrial ABCG2, we characterized stably transfected-HEK (ST-HEK) cells overexpressing ABCG2. In these ST-HEK cells, functionally active ABCG2 was detected in mitochondria, and treatment with Ko143 increased ALA-mediated mitochondrial PpIX accumulation. Moreover, the mitochondria isolated from ST-HEK cells exported doxorubicin probably through ABCG2, because the export of doxorubicin was inhibited by Ko143. The susceptibility of ABCG2 distributed in mitochondria to proteinase K, endoglycosidase H and peptide-N-glycosidase F suggested that ABCG2 in mitochondrial fraction is modified by N-glycans and trafficked through the endoplasmic reticulum and Golgi apparatus and finally localizes within the mitochondria. Thus, it was found that ABCG2 distributed in mitochondria is a functional transporter and that the mitochondrial ABCG2 regulates ALA-mediated PpIX level through PpIX export from mitochondria to the cytosol. en-copyright= kn-copyright= en-aut-name=KobuchiHirotsugu en-aut-sei=Kobuchi en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriyaKoko en-aut-sei=Moriya en-aut-mei=Koko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OginoTetsuya en-aut-sei=Ogino en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaHirofumi en-aut-sei=Fujita en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueKeiji en-aut-sei=Inoue en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShuinTaro en-aut-sei=Shuin en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YasudaTatsuji en-aut-sei=Yasuda en-aut-mei=Tatsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UtsumiKozo en-aut-sei=Utsumi en-aut-mei=Kozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UtsumiToshihiko en-aut-sei=Utsumi en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Dept Cell Chem, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Yamaguchi Univ, Grad Sch Med affil-num=3 en-affil= kn-affil=Okayama Prefectural Univ, Dept Nursing Sci, Fac Hlth & Welf Sci affil-num=4 en-affil= kn-affil=Okayama Univ, Dept Cytol & Histol, Grad Sch Med Dent & Pharmaceut Sci affil-num=5 en-affil= kn-affil=Kochi Med Sch, Dept Urol affil-num=6 en-affil= kn-affil=Kochi Med Sch, Dept Urol affil-num=7 en-affil= kn-affil=Okayama Univ, Dept Cell Chem, Grad Sch Med Dent & Pharmaceut Sci affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Cytol & Histol, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Yamaguchi Univ, Grad Sch Med END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=2 article-no= start-page=801 end-page=813 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First Synthesis of a Natural Isoxanthopterin Glycoside, Asperopterin-A en-subtitle= kn-subtitle= en-abstract= kn-abstract=The key precursor, N-2-(N,N-dimethylaminomethylene)-6-hydroxymethy1-8-methyl-3[2-(4-nitrophenypethyl]-7-xanthopterin (9) was efficiently prepared from 2,5-diamino-6-methylam1no-3H-pyrimidin-4-one (3) and ethyl 3-(tert-butyldimethylsilyloxy)-2-oxopropionate (11).

Here, we estimated the conditional association constants between the hydro gel (G-gel) and aromatic compounds by capillary electrophoresis in order to investigate the separation selectivity that is induced by the G-gel. Several aromatic compounds were separated in a solution containing GMP and potassium ion at different concentrations. The association constants were calculated by correlating the electrophoretic mobilities of the analytes obtained experimentally using a concentration of G-gel. During semi-quantitative estimation, naphthalene derivatives had larger association constants (K-ass = 10.3-16.8) compared with those of benzene derivatives (K-ass = 3.91-5.31), which means that the binding sites of G-gel match better to a naphthalene ring than to a benzene ring. A hydrophobic interaction was also found when the association constants for alkyl resorcinol were compared with those of different hydrocarbon chains. The association constants of nucleobases and tryptophan ranged from 6.05 to 12.6, which approximated the intermediate values between benzene and naphthalene derivatives. Consequently, the selective interaction between G-gel and aromatic compounds was classified as one of three types: (1) an intercalation into stacked planar GMP tetramers; (2) a hydrophobic interaction with a long alkyl chain; or, (3) a small contribution of steric hindrance and/or hydrogen bonding with functional groups such as amino and hydroxyl groups. en-copyright= kn-copyright= en-aut-name=YamaguchiKaori en-aut-sei=Yamaguchi en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Nat Sci & Technol, Div Earth Life & Mol Sci, Dept Chem affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Nat Sci & Technol, Div Earth Life & Mol Sci, Dept Chem affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Nat Sci & Technol, Div Earth Life & Mol Sci, Dept Chem en-keyword=Capillary electrophoresis kn-keyword=Capillary electrophoresis en-keyword=5 '-Guanosine monophosphate (GMP) kn-keyword=5 '-Guanosine monophosphate (GMP) en-keyword=G-gel kn-keyword=G-gel en-keyword=Association constant kn-keyword=Association constant END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=9 article-no= start-page=1720 end-page=1727 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Liposomal Delivery of MicroRNA-7-Expressing Plasmid Overcomes Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor-Resistance in Lung Cancer Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) have been strikingly effective in lung cancers harboring activating EGFR mutations. Unfortunately, the cancer cells eventually acquire resistance to EGFR-TKI. Approximately 50% of the acquired resistance involves a secondary T790M mutation. To overcome the resistance, we focused on EGFR suppression using microRNA-7 (miR-7), targeting multiple sites in the 30-untranslated region of EGFR mRNA. Two EGFR-TKI-sensitive cell lines (PC-9 and H3255) and two EGFR-TKI-resistant cell lines harboring T790M (RPC-9 and H1975) were used. We constructed miR-7-2 containing miR-7-expressing plasmid. After transfection of the miR-7-expressing plasmid, using cationic liposomes, a quantitative PCR and dual luciferase assay were conducted to examine the efficacy. The antiproliferative effect was evaluated using a cell count assay and xenograft model. Protein expression was examined by Western blotting. The miR-7 expression level of the transfectants was approximately 30-fold higher, and the luciferase activity was ablated by 92%. miR-7 significantly inhibited cell growth not only in PC-9 and H3255 but also in RPC-9 and H1975. Expression of insulin receptor substrate-1 (IRS-1), RAF-1, and EGFR was suppressed in the four cell lines. Injection of the miR-7-expressing plasmid revealed marked tumor regression in a mouse xenograft model using RPC-9 and H1975. EGFR, RAF-1, and IRS-1 were suppressed in the residual tumors. These findings indicate promising therapeutic applications of miR-7-expressing plasmids against EGFR oncogene-addicted lung cancers including T790M resistance by liposomal delivery.

en-title=Study for the structures of the HA complexes produced by Clostridium botulinum type A mutant strain kn-title=ボツリヌスＡ型菌変異株が産生するHA複合体の構造に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clostridium botulinum produces seven neurotoxin (NTX) serotypes, classified from as A to G. In culture, NTX forms protein complexes by association with non-toxic components, such as nontoxic-nonhemagglutinin (NTNH) and hemagglutinins (HA1, HA2, HA3). C. botulinum serotype A produces three types of toxin complexes, M-toxin (NTX and NTNH), L-toxin (M-toxin and HAs) and LL-toxin (dimer of L-toxin). In this study, I found three HA complexes in the culture of a nontoxigenic mutant serotype A lacking ntx and ntnh expression. The HA complexes displayed similar banding patterns on SDS-PAGE, but the staining intensities of the HA1 and HA2 bands were different. In addition, their native-PAGE banding profiles exhibited different behaviors. The large-molecular-size HA complex showed the highest activity, similar to that of an L-toxin. Based on the combined results of the PAGE and gel-filtration profiles, the differences in molecular size among the three HA complexes were thought to be caused by different numbers of HA1 and HA2 molecules. This paper reports for the first time the purification and characterization of a native HA complex of serotype A, and suggests that the HA can form complex structures without NTX and NTNH. This may help in understanding the toxin complex assembly pathway. en-copyright= kn-copyright= en-aut-name=MaShaobo en-aut-sei=Ma en-aut-mei=Shaobo kn-aut-name=馬少博 kn-aut-sei=馬 kn-aut-mei=少博 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　病原細菌学 en-keyword=ボツリヌス毒素（botulinum toxin） kn-keyword=ボツリヌス毒素（botulinum toxin） en-keyword=ボツリヌス菌（Clostridium botulinum） kn-keyword=ボツリヌス菌（Clostridium botulinum） en-keyword=血球凝集素（hemagglutinin） kn-keyword=血球凝集素（hemagglutinin） en-keyword=タンパク質複合体構造（protein complex structure） kn-keyword=タンパク質複合体構造（protein complex structure） END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=2 article-no= start-page=129 end-page=136 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Antibacterial efficacy of photocatalytic reaction on titanium dioxide-coated ceramic air filters kn-title=酸化チタン担持セラミックフィルターの光触媒反応による抗菌効果の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Titanium dioxide (TiO2) photocatalysis generates reactive oxygen species such as ・OH and ・O2-, which can effectively eliminate organic compounds. In the present study, we evaluated the antibacterial and antifungal effects of TiO2-coated ceramic air filters in both laboratory and hospital settings. Photocatalysis with the TiO2-coated ceramic filter effectively inactivated all 4 pathogenic organisms tested. Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. After the photocatalysis reaction for 4 h under UV-A (365nm, 250μW/㎠) irradiation, the percentage reductions of the number of E. coli, P. aeruginosa, S. aureus, C. albicans cells were 99.9%, 98.9%, 97.7% and 99.9%, respectively, indicating that Gram-negative bacteria are more susceptible to such photocatalysis than Gram-positive bacteria. Scanning electron microscopic analysis showed damage to the cytoplasmic membrane and cell wall by photocatalysis : consistent with above observations, the morphological change of Gram-negative E. coli was greater than that of Gram-positive S. aureus. 　Further, an air cleaner equipped with a TiO2-coated ceramic filter significantly decreased the number of bacteria floating in hospitals. 　These results indicate that air cleaners with TiO2-coated ceramic filters could be useful in reducing the incidence of nosocomial infections. en-copyright= kn-copyright= en-aut-name=NakaoMiyuki en-aut-sei=Nakao en-aut-mei=Miyuki kn-aut-name=中尾美幸 kn-aut-sei=中尾 kn-aut-mei=美幸 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　病原細菌学 en-keyword=光触媒（photocatalysis） kn-keyword=光触媒（photocatalysis） en-keyword=酸化チタン担持セラミックフィルター（TiO2-coated ceramic air filters） kn-keyword=酸化チタン担持セラミックフィルター（TiO2-coated ceramic air filters） en-keyword=抗菌効果（antimicrobial effect） kn-keyword=抗菌効果（antimicrobial effect） en-keyword=院内感染（nosocomial infection） kn-keyword=院内感染（nosocomial infection） en-keyword=空気清浄機（air cleaner） kn-keyword=空気清浄機（air cleaner） END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=2 article-no= start-page=101 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A constitutively active calcineurin encoded by an intron-containing mRNA is involved in hair cycle regulation kn-title=恒常活性型カルシニューリンによる毛周期制御機構―新しい機構に基づく発毛促進ペプチドの開発― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name=藤村篤史 kn-aut-sei=藤村 kn-aut-mei=篤史 aut-affil-num=1 ORCID= en-aut-name=TomizawaKazuhito en-aut-sei=Tomizawa en-aut-mei=Kazuhito kn-aut-name=富澤一仁 kn-aut-sei=富澤 kn-aut-mei=一仁 aut-affil-num=2 ORCID= en-aut-name=MatsuiHideki en-aut-sei=Matsui en-aut-mei=Hideki kn-aut-name=松井秀樹 kn-aut-sei=松井 kn-aut-mei=秀樹 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　細胞生理学 affil-num=2 en-affil= kn-affil=熊本大学大学院生命科学研究部　分子生理学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　細胞生理学 en-keyword=calcineurin/NFAT kn-keyword=calcineurin/NFAT en-keyword=alternative splicing kn-keyword=alternative splicing en-keyword=calcium sensitivity kn-keyword=calcium sensitivity en-keyword=hair cycle kn-keyword=hair cycle en-keyword=cyclin G2 kn-keyword=cyclin G2 END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=1 article-no= start-page=15 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hypoglycemic activity of Momordica charantia (bitter melon) kn-title=ニガウリ抽出物の血糖降下作用に関する文献的考察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diabetes mellitus (DM) represents a global health and economical problem. Many patients with DM in Asia, South America, India and East Africa have traditionally used the water extract of unripe fruits of Momordica charantia (bitter melon) as some form of complementary and alternative medicine. Studies of laboratory animals have shown the beneficial blood-glucose lowering and anti-diabetic effects of this remedy. Some oral components that bring lower blood glucose level have been isolated : charantin (sterol glycosides), charantin (polypeptide) and cucurbine-type triterpenes. Part of their actions are related to AMP-activated kinase and repression of the oxidative stress that is increased in DM. Most clinical reports are not fully convincing due to the lack of randomized control studies. The present article reviews the pharmacological and clinical effects of bitter melon with special emphasis on the anti-diabetic effects, and some effects that would require caution in the context of human trials. en-copyright= kn-copyright= en-aut-name=MankuraMitsumasa en-aut-sei=Mankura en-aut-mei=Mitsumasa kn-aut-name=万倉三正 kn-aut-sei=万倉 kn-aut-mei=三正 aut-affil-num=1 ORCID=

present approach en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although a previous study [S.S.M. Hassan, M.A. Ahmed, M.M. Saoudi, Anal. Chem. 57 (1985) 1126] had shown that a caffeine-sensitive electrode made with picrylsulfonate and 1-octanol as a cation-exchanger and a solvent mediator, respectively, had a wide working pH range (5.5-9.5) and exhibited a Nernstian response, we could not find such response in this electrode. The present result was reasonable, because the pK, value of caffeinium ion was reported to be around 0.7 and the neutral form of caffeine was predominant in the pH range examined. Thus, we reinvestigated the response characteristics of a caffeine electrode, taking into consideration the pKa value, and constructed a new electrode with a combination of the lipophilic cation-exchanger, tetrakis[3,5-bis(2-methoxyhexafluoro-2-propyl)phenyl]borate (HFPB), and the solvent mediator with high degree of dielectric constant, 2-fluoro-2'-nitrodiphenyl ether (FNDPE). This electrode showed a pH-dependent response to caffeinium ion and gave a detection limit of 50 mu M with a slope of 55 mV per concentration decade at pH 2. The use of other solvent mediators was less effective than that of FNDPE. The electrode was applied for the determination of caffeine in some central stimulants. en-copyright= kn-copyright= en-aut-name=KatsuTakashi en-aut-sei=Katsu en-aut-mei=Takashi kn-aut-name=

Two types of elemental diet (ED) were given through the gastrostomy tude for 7 days. Group A : ED containing 33% BCAA and 30% lipid (medium chain triglycerides 8.5g＋soy bean oil 1.5g/300 kcal). Group B : ED containing 17% BCAA and 1.5% lipid (soy bean oil 0.49g/300 kcal). Up to the 7th postoperative day, the excretion of nitrogen into urine decreased in group A, but no change occurred in group B. Up to the 5th postoperative day, molar ratio of 3MH to creatinine in urine in group A decreased more rapidly than in group B. Plasma concentration of albumin in group A was higher than in group B on the 7th postoperative day. Fischer ratio was significantly higher in group A than in group B on the 7th postoperative day. Both plasma and muscle levels of Tyr, Met and Gln were higher in group B than in group A, Glu and Ala were lower in group B than in group A. Essential fatty acid deficiency occurred more severely in group B than in group A. While fatty livers were microscopically observed in some livers in group B, there were few fatty deposits in group A. en-copyright= kn-copyright= en-aut-name=MizutaMinoru en-aut-sei=Mizuta en-aut-mei=Minoru kn-aut-name=水田稔 kn-aut-sei=水田 kn-aut-mei=稔 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=分岐鎖アミノ酸 kn-keyword=分岐鎖アミノ酸 en-keyword=脂肪乳剤 kn-keyword=脂肪乳剤 en-keyword=経腸栄養 kn-keyword=経腸栄養 en-keyword=脂肪肝 kn-keyword=脂肪肝 END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=3-4 article-no= start-page=287 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical and experimental studies on provocating and reducing mechanism of intractable pain Part 1.

The concentration of SP anf ENK was quantitatively estimated with radioimmunoassay using 17 adults cats. The animal were divided into 3 group, DP group (8 cats), EP group (6 cats) and untreated conrol group (3 cats). The DP group was prepared according to the method described by Shimizu and EP model was made by injection 1 ml of Freund's adjuvant subcutaneously into the unilateral face of the cats every day for 3 weeks. The amount of SP in STN markedly decreased in DP group and significantly higher in EP group than with the control group. This is explained by the fact that SP is a neurotransmitter for pain of trigeminal nerve. No significant decrease in ENK in the DP group was observed. This suggests that ENK in STN is not always controlled by the descending inhibitory system, but may be working in the propriospinal system. ENK in the EP group also showed no significant increase. This can be explained not only by the difficulty in estimating the rapid degeneration of ENK, but also by the strong participation of monoamines as well as ENK in pain relief. The role of ENK should not be overstimated and the studies including monoamines will be necessary to detemine the mechanism of pain. en-copyright= kn-copyright= en-aut-name=FujiwaraNoriaki en-aut-sei=Fujiwara en-aut-mei=Noriaki kn-aut-name=藤原則章 kn-aut-sei=藤原 kn-aut-mei=則章 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科教室 en-keyword=substance P kn-keyword=substance P en-keyword=enkephalin kn-keyword=enkephalin en-keyword=pain kn-keyword=pain en-keyword=RIA kn-keyword=RIA END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=1-2 article-no= start-page=199 end-page=207 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Structural protein analysis of intracisternal A particles in adenovirus-induced mouse tumor kn-title=内在性小胞体内 A 粒子の構成蛋白に関する研究ーアデノウイルス12型誘発マウス腫瘍に認められた粒子についてー en-subtitle= kn-subtitle= en-abstract= kn-abstract=Analysis and purfication of structural proteins of intracisternal A particles produced in adenovirus-induced tumor were described. SDS-PAGE of purified intracisternal A particles demonstrated its major structural components, K92, K70 and K55, and minor components, K43 and K37. Two dimensional gel electrophoresis indicated a pI of K70 and K55 at 6.5 and 6.3, respectively, in the presence of sodium dodecyl sulfate. Purification of the main band, K70, in SDS-PAGE using reversed phase-HPLC was difficult in the standard acidic condition, but could be achieved in the neuttral condition. Although purificatin of K70 is generally difficult because of its hydrophobicity, the method shown here will be useful for furthey study of structural proteins of intracisternal A particles. en-copyright= kn-copyright= en-aut-name=HirakawaEiichiro en-aut-sei=Hirakawa en-aut-mei=Eiichiro kn-aut-name=平川栄一郎 kn-aut-sei=平川 kn-aut-mei=栄一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学病理学講座第一病理学 en-keyword=小胞体内 A 粒子 kn-keyword=小胞体内 A 粒子 en-keyword=アデノウイルス誘発腫瘍 kn-keyword=アデノウイルス誘発腫瘍 en-keyword=構成蛋白分析 kn-keyword=構成蛋白分析 en-keyword=reversed phase-HPLC kn-keyword=reversed phase-HPLC END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1253 end-page=1265 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of new elemental diet including enriched branched chain amino acids and MCT on massive resection of small bowel in rat kn-title=脂肪（MCT）および高濃度分枝鎖アミノ酸を含有した成分栄養剤の侵襲下における効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of a new enteral diet (ED-9) that was mainly composed of BCAA enriched amino acids, MCT and maltose were examined. Rats were subjected to small bowel resection and were administered two different formula for 7 days. The animals were divided into the following four groups : Sham operation and ED-9 (Group A), sham operation and control diet (Elental) (Group B), small bowel resection and ED-9 (Group C), and small bowel resection and control diet (Group D). Body weight loss after operation was similar in both ED-9 and control diet groups. Nitrogen balance and uninary 3 Methy1-histidine excretion demonstrated that ED-9 tended to improve protein preservation. Rats given ED-9 showed elevated ketone bodies and plasma BCAA level but these levels were not extraordinarily high. In conclusion, the formula of enteral nutrition (ED-9) was as effective as Elental on postoperative nutrition in rats. en-copyright= kn-copyright= en-aut-name=SuehiroKazunaga en-aut-sei=Suehiro en-aut-mei=Kazunaga kn-aut-name=末廣和長 kn-aut-sei=末廣 kn-aut-mei=和長 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=成分栄養剤 kn-keyword=成分栄養剤 en-keyword=手術侵襲 kn-keyword=手術侵襲 en-keyword=MCT kn-keyword=MCT END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=5-6 article-no= start-page=505 end-page=515 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Zinc metabolism in the endotoxin-treated rats kn-title=エンドトキシンが体内亜鉛代謝に及ぼす影響に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of endotoxin administration on zinc metabolism was studied in rats. In the endotoxin-treated rats, serum zinc concentration was significantly reduced as compared to saline-treated rats (control group). On the other hand, hepatic zinc concentration was significantly increased after endotoxin administration as compared to the control group. However, the zinc concentrations of the liver cell components showed slightly dissimilarity. In the mitochondria and cytsol, the concentration increased significantly after endotoxin administration as compared to the control group, whereas no change was observed in the microsomes. Furthermore, we have examined whether the increase of the zinc level in the cytosol of the liver is associated with zinc-binding protein metallothioneins (MTs) or not. MTs also increased significantly after endotoxin administration. Furthermore hepatic MTs were analyzed for MT isoforms. In the endotoxin-treated MT-II was the major Iso-MT. Judging from these results and some other published reports, the role of zinc metabolism in endotoxemia is proposed to be as follows. In endotoxemia the serum zinc concentration is reduced and as a result the production of superoxide by polymorphonuclear leukocytes is increased as zinc has an inhibitory effect on it. This free radical helps the host against the organism. On the other hand zinc accumulation in the liver following endotoxin administration increases the activity of the zinc binding-enzyme and also stabilizes the plasma membrane. MTs induced by endotoxin protect the host from the harmful effects of the free radical in the host by its scavenging action. en-copyright= kn-copyright= en-aut-name=MatsumiMasaki en-aut-sei=Matsumi en-aut-mei=Masaki kn-aut-name=松三昌樹 kn-aut-sei=松三 kn-aut-mei=昌樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=エンドトキシン kn-keyword=エンドトキシン en-keyword=亜鉛 kn-keyword=亜鉛 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=1-2 article-no= start-page=129 end-page=141 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Biochemical changes in the rat brain in the chronic stage after transient forebrain ischemia kn-title=一過性虚血後の慢性期ラット脳における生化学的変化に検する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, cases of sequelae of cerebrovascular disease such as vascular dementia due to death of many neurons have been increasing. Such neuronal death following brain ischemia had been considerd to be due to an energy deficiency resulting from an impaired respiratory chain. However, the detection of the delayed neuronal death showed that neuronal death is not caused by mere energy deficiency. Most previous studies on delayed neuronal death focused on the changes in morphology and energy metabolism in the acute to subacutte stage. There are few reports concerning biochemical changes in the chronic stage, especially in neurotransmitter receptors. Transient ischemia for 20 minutes in a rat four-vessel occlusion model was induced, and serial histological and biochemical changes were evaluated until the chronic stage. Destruction of pyramidal cells in the CAI area of the hippocampus was completed by 10 days after cerebral ischemia followed by recirculation of cerebral blood flow. Light microscopy showed no progression after this day. The level of acetylcholine (ACh) was significantly decreased in the hippocampus, striatum, and frontal cortex at the termination of ischemia but recovered to normal 21 days after recirculation of cerebral blood flow. The binding sites of muscarinic ACh receptors (mACh-R) per usit of protein were increased in the hippocampus 21 days after recirculation of blood flow. However, no changes were observed in the total number of mACh-R in the entire hippocampus. Thuse finings suggest no changes in the ACh neuronal system in the chronic stage and no direct association between this ayatem and delayed neuronal death. On the other hand, N-methyl-D-aspartate (NMDA) receptors, a subtype of glutamate receptirs, showed no change in the hippocampus until after 10 days, but decreased to half after 21 days despite no evidence of histological progression of neuronal death. Thus, delayed neuronal death after transient forebrain ischemia appears to be deu to release of glutamate, an excitatory amino acid. Our findingd show the specific death of neurons with NMDA receptors for glutamate. en-copyright= kn-copyright= en-aut-name=YoshikawaHiroshi en-aut-sei=Yoshikawa en-aut-mei=Hiroshi kn-aut-name=吉川寛 kn-aut-sei=吉川 kn-aut-mei=寛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳代謝研究施設機能生化学部門 en-keyword=ischemia kn-keyword=ischemia en-keyword=acetylcholine kn-keyword=acetylcholine en-keyword=muscarinic acetylcholine receptor kn-keyword=muscarinic acetylcholine receptor en-keyword=N-methyl-D-aspartate (NMDA) receptor kn-keyword=N-methyl-D-aspartate (NMDA) receptor en-keyword=delayed neuronal death kn-keyword=delayed neuronal death END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1225 end-page=1235 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects and optimal dose of recombinant human superoxide dismutase during cardiopulmonary bypass kn-title=体外循環下における心筋の虚血再灌流に関する検討-h-SOD の効果と至適投与量- en-subtitle= kn-subtitle= en-abstract= kn-abstract=The efficacy of recombinant human superoxide dismutase (h-SOD) was examined and its optimal dose when given before reperfusion in an experimental canine cardiopulmonary bypass (CPB) model was determined. Mongrel dogs were placed on total CPB for 130 minutes without aortic cross clamping (Group Ⅰ). Others were placed on CPB for 120 minutes aortic cross clamping with intermittent administration of cardioplegic solution and core cooling (Group Ⅱ). Before reperfusion, saline, and 1 mg, 3 mg, 10 mg and 20 mg h-SOD per kilogram were administered via the aortic root as a bolus injection (Group Ⅲ,Ⅳ,Ⅴ,Ⅵ,Ⅶ). Reperfusion after hypothermic global ischemia with aortic cross clamping deteriorated cardiac function (cardiac index, left ventricular maximum dp/dt), increased myocardial water content and increased cardiac enzyme release (creatinine kinase MB isozyme, α-hydroxybutyric dehydrogenase). Administration of 3 mg/㎏ h-SOD significantly ameliorated this reperfusion injury, protected myocardial function early after CPB and gave a desirable peak serum h-SOD concentration. en-copyright= kn-copyright= en-aut-name=YamadaYukio en-aut-sei=Yamada en-aut-mei=Yukio kn-aut-name=山田幸夫 kn-aut-sei=山田 kn-aut-mei=幸夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=体外循環 kn-keyword=体外循環 en-keyword=心筋保護 kn-keyword=心筋保護 en-keyword=再灌流障害 kn-keyword=再灌流障害 en-keyword=free radicals kn-keyword=free radicals en-keyword=superoxide dismutase kn-keyword=superoxide dismutase END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=1-2 article-no= start-page=37 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation for malignancy using DNA analysis and the effect of medroxyprogesterone acetate on cell kinetics in primary breast cancer kn-title=核 DNA 量による乳癌の悪性度判定ならびに内分泌療法の作用機序の研究―Flow cytometry による解析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate for primary breast cancer, flow cytometric DNA analysis has been performed on 105 paraffin-embedded tissues. The S-phase fraction and proliferation index correlated significantly with clincopathological factors, sunh as n-number, tumor size, histological stage and hormone receptors. However, there was no correlation between the level of ploidy and the clinicopathological factors. DNA analysis using flow cytometry was found to be useful for the estimation of prognosis and evaluation of malignancy of breast cancer. The effect of medroxyprogesterone acetate (MPA) on primary breast cancer cell kinetics was investigated by flow cytometry. Nuclear DNA contents were measured in 67 cases. MPA, 1,200mg/day, was orally administered for two weeks in 12 cases (MPA group) and the remain-ing cases (n-MPA group) served as the controls, until the day before operatopn. The DNA histograms were compared between both groups. The mean percentage of G0 + G1 phase was higher and that of S-phase and G2 + M phase, lower, in the MPA group than in the n-MPA group. Especially in estorogen receptor-positive and premenopausal cases, significant differ-ences were present between both groups. These results suggest that MPA could inhibit DNA synthesis with a delay of the cell cycle progression in human breast cancer. en-copyright= kn-copyright= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name=土井原博義 kn-aut-sei=土井原 kn-aut-mei=博義 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=flow cytometry kn-keyword=flow cytometry en-keyword=乳癌 kn-keyword=乳癌 en-keyword=核 DNA 量 kn-keyword=核 DNA 量 en-keyword=悪性度 kn-keyword=悪性度 en-keyword=medroxyprogesterone acetate (MPA) kn-keyword=medroxyprogesterone acetate (MPA) END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=305 end-page=313 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Specific activity of catalase in the blood from Japanese hypocatalasemia, mice hypocatalasemia and mice acatalasemia kn-title=日本人ヒポカタラセミア, マウスヒポカタラセミア, マウスアカタラセミアの血球カタラーゼの比活性度 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Blood catalase was purified by CM-cellulose followed by DEAE-cellulose and Sephadex G-150 from blood of Japanese individuals.

Liver catalase was purified twice from the ammonium sulfate fraction of mice liver supernatant by using the same Sephadex G-200 column. In the same way as for humans, the rabbit was immunized and serum was taken as anti-mice liver catalase tabbit serum, and was used for the immunotitration of blood catalase from acatalasemic, hypocatalasemic and normal mice.

That activity was the same as that of catalase in the blood of normal Japanese individuals. In contrast to this, the specific activity in the blood of hypocatalasemic mice was lower than that of normal mice. Specific activity of residual catalase in the blood of acatalasemic mice showed the lowest value among the activities in the blood of normal, hypocatalasemic and acatalasemic mice. en-copyright= kn-copyright= en-aut-name=FujiiYasuhito en-aut-sei=Fujii en-aut-mei=Yasuhito kn-aut-name=藤井保人 kn-aut-sei=藤井 kn-aut-mei=保人 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学講座 en-keyword=日本人ヒポカタラセミア kn-keyword=日本人ヒポカタラセミア en-keyword=変異マウス kn-keyword=変異マウス en-keyword=血球カタラーゼ kn-keyword=血球カタラーゼ en-keyword=比活性度 kn-keyword=比活性度 en-keyword=免疫滴定 kn-keyword=免疫滴定 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=293 end-page=303 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The level of lipid peroxide and the effect of human superoxide dismutase on cardiac ischemia/reperfusion injury kn-title=心筋虚血・再灌流障害における過酸化脂質の動態と h-SOD 投与効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the role of free radicals and the efficacy of human superoxide dismutase (h-SOD) on cardiac ischemia/reperfusion injury, adult mongrel dogs were placed on a cardiopulmonary bypass (CPB). Aorta was cross clamped for 120 minutes and crystalloid cardioplegic solution was administered into the aortic root every 30 minutes. Sixteen dogs were divided into the control group and non cross clamped group (XCL(-)group). They were placed on total CPB for 130 minutes without an aortic cross clamp. The control group showed higher thiobarbituric acid reactive substance (TBARS) release from heart in early reperfusion phase (P<0.05), and suppressed recovery of cardiac index (CI) and max dp/dt at 60 minutes after reperfusion (P<0.01 and P<0.05, respectively) than XCL (-) group. Eight dogs were administered saline and 32 dogs were administered saline and h-SOD into the aortic root just before reperfusion. Dogs, administered h-SOD, were devided into four groups by the dese of h-SOD, group I : 1mg/kg, group II : 3mg/kg, group III : 10mg/kg, and group IV : 20mg/kg. Between control and saline groups, no significant difference was found. Groups I and II showed suppressed TBARS release from the heart in the early reperfusion phase than the control group (P<0.01 and P<0.05, respectively). Groups II and III showed higher recovery of CI at 60 minutes after reperfusion than the control group (P<0.01 and P<0.05, respectively). In conclusion, significantly higher TBARS was released from the heart and recovery of cardiac function was suppressed in cardiac ischemia/reperfusion injury. The h-SOD administtation was effective to protect the heart from cardiac ischemia/reperfusion injury. en-copyright= kn-copyright= en-aut-name=IkedaEiji en-aut-sei=Ikeda en-aut-mei=Eiji kn-aut-name=池田英二 kn-aut-sei=池田 kn-aut-mei=英二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=体外循環 kn-keyword=体外循環 en-keyword=心筋保護 kn-keyword=心筋保護 en-keyword=再灌流障害 kn-keyword=再灌流障害 en-keyword=TBA kn-keyword=TBA en-keyword=h-SOD kn-keyword=h-SOD END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=625 end-page=637 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Metallothionein gene expression in rat liver following intraperitonal endotoxin administration kn-title=エンドトキシン投与ラットにおける肝内メタロチオネイン遺伝子発現に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the functions of hepatic metallothioneins (MTs) after the administration of endotoxin (lipopolysaccharide : LPS), we investigated the expression on MT genes in the bacterial endoxin-treated rat liver by Norhern blot hybridization and in situ hybridization methol with riboprobes synthesized from mouse cDNA of MT-Ⅱ chronologically. Northern blot analysis revealed a rapid increase in the amount of MT gene transcripts in the liver 3 hours after the administration of LPS, with a maximum at 6 to 12 hours followed by a gradual decrease. In the in situ hybridization method, MT genes are expressed in the liver lobule for 3 hours after the adiminstration of LPS, and hepatocellular damage was observed at 6 hours after the LPS administration initially and expanded most extensively at 18 hours. During this peripd, MT genes are expressed in intact tissue intensely and specifically. At 24 hours after the administration, transcripts of the MT gene were detected in intact hepatocytes around the shrinking necrotic area. These findings suggest that MTs protect the liver cells by scavenging the free radicals, which probably cause liver cell damage due to LPS administration, and that MTs provide the zinc ions necessary for stabilizing the cell membrane and to heal the liver cell damge. en-copyright= kn-copyright= en-aut-name=TagaNaoyuki en-aut-sei=Taga en-aut-mei=Naoyuki kn-aut-name=多賀直行 kn-aut-sei=多賀 kn-aut-mei=直行 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=エンドトキンショック kn-keyword=エンドトキンショック en-keyword=メタロチオネイン kn-keyword=メタロチオネイン en-keyword=in situ hybridization kn-keyword=in situ hybridization END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=617 end-page=624 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Ascorbic acid incerases 1,25-dihydroxyvitamin D(3) effect in human osteosaroma cell line MG63 kn-title=アスコルビル酸による 1,25dihydroxyvitaminD(3) 作用の増強―培養ヒト骨肉腫細胞 MG63 における検討― en-subtitle= kn-subtitle= en-abstract= kn-abstract=We eximined the interaction between 1,25-dihydroxyvitamin D(3) and ascorbic acid in the human osteosarcoma cell MG63 by measuring alkaline phosphatase (ALP) activity. Both vitamins induced ALP activity in this cell line. Simultaneous addition of both ascorbic and 1,25-dihydroxyvitamin D(3) induced much higher ALP activity than each vitamin alone. Pretreatment of MG63 with ascorbic acid or type I collagen, increased the ALP activity induced by 1,25-dihydroxyvitamin D(3). Binding assay anf immunoblotting analysis showed that the number of vitamin D receptors was increased in MG63 pretreated with ascorbic acid. In conclusion,ascorbic acid stimulates collagen production of MG63, and collagen increases the vitamin D receptor content. The increase in vitamin D receptor content potentiates the activity of 1,25-dihydroxyvitamin D(3) in this cell line. en-copyright= kn-copyright= en-aut-name=KuriharaMakoto en-aut-sei=Kurihara en-aut-mei=Makoto kn-aut-name=栗原信 kn-aut-sei=栗原 kn-aut-mei=信 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科学教室 en-keyword=MG63 kn-keyword=MG63 en-keyword=1,25dihydroxyvitaminD(3) kn-keyword=1,25dihydroxyvitaminD(3) en-keyword=ascorbic acid kn-keyword=ascorbic acid en-keyword=type I coollagen kn-keyword=type I coollagen en-keyword=vitaino D recepter kn-keyword=vitaino D recepter END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=161 end-page=171 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The accumulation of metallothionein in the rat kidney injured by temporal ischemia kn-title=虚血性腎傷害による亜鉛代謝と腎内メタロチオネインの変動に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The renal and hepatic metallothionein (MT) and serum zinc levels were studied in rats following renal ischemia, to clarify the effects of renal damage on the zinc metabolism.

The accumulation of hepatic MT was stimulated by sham operation and was augmented furthermore by renal ischemic damage. The renal MT level increased gradually and reached the maximum on the 3rd day in the bilateral renal ischemic rat. The MT level in the injured kidney was higher than that in the intact kidney in the unilateral renal ischemic rat. These results suggested that the mechanism of MT synthesis in the kidney was different from that in the liver, and that some local factor might induce MT in the injured kidney. en-copyright= kn-copyright= en-aut-name=MizukawaShun-ichi en-aut-sei=Mizukawa en-aut-mei=Shun-ichi kn-aut-name=水川俊一 kn-aut-sei=水川 kn-aut-mei=俊一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=亜鉛 kn-keyword=亜鉛 en-keyword=虚血性急性腎不全 kn-keyword=虚血性急性腎不全 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=105 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Alterations of neuropeptides in MPTP-treated mouse brain kn-title=1-Methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)　を用いたパーキンソニズム・モデルマウスにおける脳内神経ペプチドに関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1-Methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) has been shown to destroy the nigrostriatal dopaminergic system, inducing biochemical and histopathological changes resembling Parkinson's disease. Biochemical changes, especially changes of neuropeptides were determined 1,2 or 6 weeks after MPTP treatment in various regions of the mice brain. The dopamine (DA) concentration decreased to 22% of the control level in the striatum 1 week after MPTP treatment, but recovered to 50% of the control level 6 weeks after MPTP treatment. The decrease in the noradrenaline concentration was less than that of DA. Amine fluorescence histochemistry revealed, markedly decreased amine fluorescnece in the striatum 6 weeks after MPTP treatment, and this decrease in amine fluorescence was recovered after levodopa treatment. The results of a pole thst revealed the bradykinesia of MPTP-treated mice and it was attenuated b y levodopa and amantadine hydrochloride treatments. Among the neuropeptides tested, somatostatin (SOM) increased 1 week after MPTP treatment in the striatum and the thalamus＋midbrain but decreased 6 weeks after MPTP treatment in the striatum and the hippocampus. In the striatum the decreased SOM recovered with levodopa treatment. Thus, the SOM might be regulated by a dopaminergic system. On the other hand, in the cerebral cortex, while no changes appeared in the SOM concentration after MPTP treatment, the concentration decreased significantly with levodopa treatment. Other neuropeptides such as substance P, cholecystokinin-octapeptide and thyrotropin releasing hormone did not show any significant changes up to 6 weeks after MPTP treatment. en-copyright= kn-copyright= en-aut-name=KawataMakio en-aut-sei=Kawata en-aut-mei=Makio kn-aut-name=河田牧男 kn-aut-sei=河田 kn-aut-mei=牧男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳代謝研究施設機能生化学部門 en-keyword=MPTP kn-keyword=MPTP en-keyword=parkinsonism kn-keyword=parkinsonism en-keyword=neuropeptide kn-keyword=neuropeptide en-keyword=somatostatin kn-keyword=somatostatin en-keyword=levodopa kn-keyword=levodopa en-keyword=dementia kn-keyword=dementia END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=517 end-page=537 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study of serum enzyme leucine aminopeptidase (LAP) isozyme in lung cancer kn-title=肺癌患者における血清酵素 Leucine Aminopeptidase (LAP) Isozyme の研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum leucine sminopeptidase (LAP) activity and its isozyme fraction were assayed in 73 primary lung cancer patients with the passage of time before the operation to 3 years after the operation.

There was no significant difference in the Y fraction with the size of tumor before the operation, but a significant fall wes observed after curative resection.

Snginificantly posotive correlations were noted in vitro between TP and plasma/gas partition coefficient, and between Ht and red cell/gas partition coefficient. However, the change in blood/gas partition coefficient appeared to be affected by TP. Sevoflurane MAC and seveflurane concentration in blood at 1 MAC rose in positive correlation with the rise of TP with or without nitrous oxide in combination, but there was no correlation with Ht. This seemed to be related to the predominancy of sevoflurane to dissolve into the plasma. The sevoflurane MAC and sevoflurane concentration in blood were significantly lower in the 33% nitrous oxide combined group than those in the oxygen alone group, but there was no significant difference between the 66% nitrous oxide combined group and the 33% nitrous oxide combined group.

Among the 3-hydroxyanthranilic acid metabolites, o-aminophenol induced spike discharges a few min after the administration, and the spike discharges a few min after the administrations, and the spike discharges lasted 60 min.

In the [5HT＋ADP] -induced aggregation. The inhibitory activity was in the order of (－)-desmethoxyverapamil (D888), mianserin (MA), ketanserin, AE>diltiazem, nicardipine, yohimbine.

Only AE among these drugs inhibited ADP-induced aggregation. The present findings indicate that the Ca antagonist D888, 5HT(2) antagonist MA and α(2) antagonist YH acted simultaneously as 5HT(2) and α(2) receptor inhibitors and imply an apparent interaction between these receptors. Since both of the aggregation responses required extracellular Ca(2+) and were modulated by Ca(2+) concentrations, the mechanism of interaction may be attributed to intracellular Ca(2+)-signaling systems. en-copyright= kn-copyright= en-aut-name=OkadaHidetoshi en-aut-sei=Okada en-aut-mei=Hidetoshi kn-aut-name=岡田英俊 kn-aut-sei=岡田 kn-aut-mei=英俊 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳代謝研究施設病態生化学部門 en-keyword=platelet aggregation kn-keyword=platelet aggregation en-keyword=serotonin(2) receptors kn-keyword=serotonin(2) receptors en-keyword=α(2)-adrenergic receptors kn-keyword=α(2)-adrenergic receptors en-keyword=calcium antagonists kn-keyword=calcium antagonists END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=457 end-page=469 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Metallothionein induction in the rat kidneys by endotoxin and zinc administration kn-title=エンドトキシンおよび亜鉛投与ラットにおける腎メタロチオネインの誘導に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metallothionein (MT) induction in the rat kidneys by endotoxin and zinc was investigated at the MT-protein level and the MT-mRNA level.

Two MT-protein isoforms, MT-Ⅰ and MT-Ⅱ, were induced by administration of both endotoxin and zinc. The maximum levels of the proteins were seen 9 hr after administration of endotoxin and zinc. The span life of the renal MT induced by zinc was shorter than that of the liver MT induced by zinc. The MT-Ⅱ isoform was predominantly induced by both inducers, endotoxin and zinc, and the ratios of MT-Ⅱ to MT-Ⅰ were relatively constant.

Patients with idiopathic hemochromatosis showed a reduction in the Fe-TfR count on alveolar macrophages (5.0×10(4)/cell) as compared to that in healthy individuals (19.88±8.19×10(4)/cell). Concerning the Fe-TfR binding constant, no differnce was observed between patients with idiopathic hemochromatosis and healthy controls. The Fe-TfR count on alveolar macrophages was significantly lower in iron-overloaded guined pigs than in normal cntrols. The count was significantly elevated in iron-deficient guinea pigs. Concerning the Fe-TfR binding constant, none of the iron-overloaded and iron-deficient groups showed any significant difference from the normal controls. These findings suggest that experimentally-induced iron overload and iron deficiency may be autoregulated by intracellular iron levels. en-copyright= kn-copyright= en-aut-name=InadaToshio en-aut-sei=Inada en-aut-mei=Toshio kn-aut-name=稲田俊雄 kn-aut-sei=稲田 kn-aut-mei=俊雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Transferrin receptor kn-keyword=Transferrin receptor en-keyword=Hemochromatotis kn-keyword=Hemochromatotis en-keyword=Iron overloaded kn-keyword=Iron overloaded en-keyword=Iron depleted Alveolar macrophage kn-keyword=Iron depleted Alveolar macrophage END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=973 end-page=981 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of quercetin on thermotolerance in NIH 3T3 cells : From a view point of cell survival kn-title=NIH 3T3 細胞の温熱耐性に対するケルセチンの作用　第1編　細胞の生存率からみたケルセチンの作用 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The inhibition of thermotolerance development by quercetin was examined in NIH 3T3 cells.

Diferric transferrin receptors were also found on guinea pig alveolar macrophages (2.25±0.78×10(4)) and peritoneal macrophages (1.6±0.2×10(3)), while they were absent on rat alveolar and peritoneal macro-phages. Scanning electron microscopic findings in guinea pig alveolar macrophages revealed a patch-formed distribution of apotransferrin receptors and diferric transferrin receptors on the characteristic ruffle-covered surface of macrophages. The number of transferrin rece-ptors varied among individual cells even within the same species or same organs. These findings suggest that the macrophages with transferrin receptors in various organs of human and guinea pigs are heterogeneous among different species and cells, and have different functions in iron metabolism. en-copyright= kn-copyright= en-aut-name=InadaToshio en-aut-sei=Inada en-aut-mei=Toshio kn-aut-name=稲田俊雄 kn-aut-sei=稲田 kn-aut-mei=俊雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Transferrin receptor kn-keyword=Transferrin receptor en-keyword=RIA kn-keyword=RIA en-keyword=SEM kn-keyword=SEM en-keyword=Macrophage kn-keyword=Macrophage en-keyword=Monocyte kn-keyword=Monocyte END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=3-4 article-no= start-page=355 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Superoxide dismutase activity in rheumatoid arthritis : its measurement and clinical implication kn-title=慢性関節リウマチにおける Superoxide Dismutase (SOD) 活性の測定と臨床的意義に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In chronic inflammations of rheumatoid arthritis (RA), polynuclear leukocytes, macro-phages, synovial cells and other inflammatory cells release reactive oxygen species (ROS) and cause tissue impairment, and are regarded as the responsible agents in this pathological condition. In the present study, the electron spin resonance (ESR) method was used to measure superoxide dismutase (SOD) in 76 knee synovial fluid samples from rheumatoid knee joints and to compare the results with those of osteoarthritic knee joints and postraumatic arthritis. There was no significant difference in the SOD activity between PA and OA patients knee joint fluid, which was higher than that in patients with posttraumatic arthritis. The SOD activity in RA knee joint fluid showed no correlation with serum CRP (C-reactive protein) or erythrocyte sedimentation rate, indices of inflammation. According to Larsen's Grading of rtheumatoid knee radiography, patients with moderate RA changes (grade Ⅲ or Ⅳ) show higher SOD activity than patients with early (grade Ⅰ or Ⅱ) and terminal RA (grade　Ⅴ). Our findings suggest that the SOD actvity in RA knee joint fluid is a valid index of articular destruction. en-copyright= kn-copyright= en-aut-name=OnoueJinichi en-aut-sei=Onoue en-aut-mei=Jinichi kn-aut-name=尾上仁一 kn-aut-sei=尾上 kn-aut-mei=仁一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部整形外科学教室 en-keyword=superoxide dismutase kn-keyword=superoxide dismutase en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=electron spin resonance kn-keyword=electron spin resonance END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=963 end-page=972 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of pathogenic factors of Proteus mirabilis isolated from urinary tract infection kn-title=尿路感染症患者分離 Proteus mirabilis の病原性発現因子の解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Proteus mirabilis has several pathogenic factors such as adherent ability to urinary tract epitherial cells, urease, motility and resistance to urine.

In this study, both the secretion of IGFBP-3 from a human osteosarcoma cell line MG63 and effects of 1, 25-dihydroxyvitamin D(3) (1,25-(OH)(2)D(3)) on the production of IGFBP-3 were investigated. The β subunit of IGFBP-3 was detected immunocytochemically in the perinuclear cytoplasm of MG63 cells. Immunoblotting and SDS-PAGE analysis revealed that both 140-150KD MW entire molecules and 40-60KD MW β subinit molecules of IGFBP-3 were present in cell-conditionel media. 1,25-(OH)(2)D(3) stimulated the production of the IGFBP-3 molecule by MG63 cells. The concentration of IGFBP-3 conditioned media began to rise at 24 hours after the addtiton of 10(-9)M of 1,25-(OH)(2)D(3) and reached the peak level at 48 hours. Dose-dependent effects of 1,25-(OH)(2)D(3) were demonstrated. These findings show that MG63 produces IGFBP-3 and that 1,25-(OH)(2)D(3) stimulates the production of this protein. These findings suggest that the synergistic effects of 1,25-(OH)(2)D(3) on the action of IGF-I on osteoblastic cells may be modulated by locally produced IGFBP-3. en-copyright= kn-copyright= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name=守分正 kn-aut-sei=守分 kn-aut-mei=正 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科学教室 en-keyword=1,25 (OH)(2)D(3) kn-keyword=1,25 (OH)(2)D(3) en-keyword=insulin-like growth factor binding protein 3 kn-keyword=insulin-like growth factor binding protein 3 en-keyword=human osteosarcoma cell line MG63 kn-keyword=human osteosarcoma cell line MG63 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=951 end-page=962 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The cyclic AMP-generating system of cobalt-induced epileptic cerebral cortex kn-title=コバルト誘導てんかん性大脳皮質のサイクリック AMP 合成系に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A cobalt chloride solution was injected into the unilateral sensorimotor cortex of rats to induce epileptic activity. The cyclic AMP contents of slices incubated with or without adenosine and 2-chloroadenosine were determined in four cortical areas after electroencephalography and behavioral examination in cobalt-injected rats. Electrographic spike activity appeared immediately after injection of cobalt. In the majority of cobalt-injected rats, the spike activity was dominant in the primary epileptic region of the cortex. The spike frequency reached a maximum level two to three weeks after the injection and declined thereafter. The electrographic activity was followed by abnormal behavior. Adenosine and 2-chloroadenosine elevated the cyclic AMP levels in the cortical slices 6-to 10-fold and 10-to 16-fold, respectively. The elicitation of cyclic AMP accumulation was strongly inhibited by the adenosine antagonist 8-phenyltheophylline. The cyclic AMP accumulation elicited by adenosine or 2-chloroadenosine was increased in the primary cortical area of cobalt-induced epilepsy, but in the other cortical areas there was no deviation in cyclic AMP accumulation. The increase in cyclic AMP accumulation was observed regardless of the presence or absence of the adenosine uptake inhibitor dipyridamole, phosphodiesterase inhibitor Ro 20-1724, and adenosine deaminase. The increased accumulation of cyclic AMP in the primary epileptic cortex was detected as early as 8 days after the injection. The cyclic AMP accumulation slightly increased thereafter. It reached a plateau 17 to 19 days after the injection and then turned to the control levels, in harmony with the electrographic and behavioral profiles. These findings suggest that alterations in adenosine-sensitive generation of cyclic AMP in the primary epileptic region of the cortex are part of the neurochemical process of cobalt-induced epilepsy. en-copyright= kn-copyright= en-aut-name=AsakiHideki en-aut-sei=Asaki en-aut-mei=Hideki kn-aut-name=浅木秀樹 kn-aut-sei=浅木 kn-aut-mei=秀樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 en-keyword=サイクリック AMP kn-keyword=サイクリック AMP en-keyword=アデノシン kn-keyword=アデノシン en-keyword=2 - クロロアデノシン kn-keyword=2 - クロロアデノシン en-keyword=コバルト誘導てんかん kn-keyword=コバルト誘導てんかん en-keyword=ラット大脳皮質 kn-keyword=ラット大脳皮質 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=899 end-page=903 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=High-performance liquid chromatographic determination of ascorbic acid and total ascorbic acid in Chinese vegetables kn-title=高速液体クロマトグラフィーによる中国野菜中のアスコルビン酸および総アスコルビン酸の定量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A Simple high-performance liquid chromatographic method is described for the rapid estimation of ascorbic acid and total ascorbic acid.

In this study, the effects of guanidino compounds (5mM) on MAO-A, MAO-B and COMT were examined to invastigate the role of guanidino compounds in CNS function. MAO-A activity was decreased by α-guanidinoglutaric acid (GGA) and guanidinoethanesulfonic acid, and increased by arginine (Arg) and N-acetylarginine at a low substrate concentration (4.33μM). MAO-B activity was decreased by creatinine (CRN), δ-guanidinovaleric acid (GVA) and methylguanidine (MGua) at a high substrate concentration (3.125mM), and decreased by CRN, GVA, MGua, Arg, guanidine, 2-guanidinoethanol, β-guanidinopropionic acid, guanidinosuccinic acid and homoarginine at a low substrate concentration (62.5μM). GVA, CRN and MGua acted as competitive inhibitors on MAO-B and their calculated Ki values were 9.47mM, 14.5mM and 29.4mM, respectively. Although the guanidino compounds tested had no effect on COMT activity at a high substrate concentration (600μM), GSA and GVA inhibited COMT activity at a low substrate concentration (75μM). These results suggest that some guanidino compounds influence catabolic enzymes of indoleamine and catecholamines to control CNS function. en-copyright= kn-copyright= en-aut-name=HukuyamaKatsuhisa en-aut-sei=Hukuyama en-aut-mei=Katsuhisa kn-aut-name=福山勝久 kn-aut-sei=福山 kn-aut-mei=勝久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属分子細胞医学研究施設神経情報学部門 en-keyword=guanidino compounds kn-keyword=guanidino compounds en-keyword=monoamine oxidase A kn-keyword=monoamine oxidase A en-keyword=monoamine oxidase B kn-keyword=monoamine oxidase B en-keyword=chatechol-O-methyltransferase kn-keyword=chatechol-O-methyltransferase END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1079 end-page=1086 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on platelet function in bronchial asthma Part 2.

The results were as follows : 1) The production of 12HETE from platelets of asthmatics were significantly higher than that of normal subjects(p<0.01). 2) Blastogenesis of lymphocytes was significantly suppressed by addition of platelets(p<0.05). 3) Blastogenesis of lymphocytes was significantly suppressed by addition of more than 12.5ng/ml of 12HETE, 10ng/ml of transforming growth factorβ(TGE-β) or 50ng/ml of serotonin.

We previously reported an inverse correlation between mean number of TfR expressed and stainable iron granules (SIGs) of erythroblasts (EBLs) in normal subjects. In MDS, EBLs contain an increased number of SIGs, though the mechanism of this phenomenon is not well understood. In this report, expression of surface transferrin receptor (TfR) on bone marrow EBLs was examined in comparison with the number of SIGs in 11 patients with myelodysplastic syndrome (MDS) and 11 patients with acute leukemia (AL). The mean numbers of TfR from MDS (5.56±1.35x10(5)) and AL (5.73±2.25x10(5)) were not different from those of normal subjects (5.00±1.80x10(5)). However, in MDS the mean number of TfR from 8 patients (72%) was similar to the normal level in spite of the increased mean number of SIG. Four of the 11 patients with AL showed a similar change such as MDS in TfR, but notably 2 of those 4 patients were AL transformed from MDS. There is a correlation (r＝0.61) between TfR and MCV in MDS different from that in healthy subject. These findings suggest that TfR expression on EBLs, from MDS may escape from the regulation by the cellular iron content as iron-TfR regulation disturbance. en-copyright= kn-copyright= en-aut-name=TsuyunoRitsurou en-aut-sei=Tsuyuno en-aut-mei=Ritsurou kn-aut-name=露野理津朗 kn-aut-sei=露野 kn-aut-mei=理津朗 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=transferrin receptor kn-keyword=transferrin receptor en-keyword=stainable iron granule kn-keyword=stainable iron granule en-keyword=myelodysplastic syndrome kn-keyword=myelodysplastic syndrome en-keyword=acute leukemia kn-keyword=acute leukemia END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1069 end-page=1078 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on platelet function in bronchial asthma Part 1.

However, there were no significant differences between steroid dependent and non-steroid dependent intractable asthmatics in severe asthma. 4) The releasability of serotonin was decreased in most cases during asthmatic attack and was suppressed by aminophyllin. 5) The serotonin-releasability of platelets stimulated by anti-IgG of Candida antigen was remarkably enhanced aftre incubation with serum, although releasability was not increased with heart-treated serum. These results suggest that platelets play an important role in bronchoconstriction induced by various immunological reactions involved with complement activation in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=SunamiKoji en-aut-sei=Sunami en-aut-mei=Koji kn-aut-name=角南宏二 kn-aut-sei=角南 kn-aut-mei=宏二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=platelet kn-keyword=platelet en-keyword=serotonin kn-keyword=serotonin en-keyword=bronchial asthma kn-keyword=bronchial asthma END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1033 end-page=1046 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=In vitro effects of halothane exposure on hepatic microsomal cytochrome P-450 in rats kn-title=ハロタンのラット肝ミクロソーム中チトクロームP-450に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hepatic microsomes were collected from male rats in which hepatic microsomes enzymes were induced by phenobarbital (PB) and untreatend rats.

Microsomal enzyme contents and enzyme activities were measured. The contents of cytochrome P-450 were decreased in PB-induced microsomes (PB-microsomes) and the decrease wes greater with 10% halothane or 20-minute incubation than with 2% halothane or 5-minute incubation. The contents of cytochrome P-450 in non-PB-microsomes were also decreased by 10% halothane. Heme contents were decreased in PB-microsomes by 10% halothane, and in non-PB-microsomes by 20-minute incubation with 2% halothane. The activities of aminopyrine demothylation were decreased both in PB and non-PB-microsomes and the decrease was greater with 10% halothane. The activities of aniline hydroxylation were decreased in PB and non-PB-microsomes, and after 20-minute incubation. The contents of cytochrome b(5), the tetrabutylic acid reacting substances and the activities of cytochrome P-450 reductase were not changed.

The changes include increse in sideroblasts and maturation delay. Expression of the transferrin receptor (TfR) has been known to correlate with stainable iron and cell maturation. To clarify whether the regulation mechanism of TfR on bone marrow EBLs is altered in MDS and acute leukemia (AL), TfR expression on EBL from MDS and AL were measured in individual cells as well as cell morphology, stainable iron granules (SIGs) in EBLs and cellular hemoglobin content using the morphometric method established in our laboratory. Generally, the number of TfR and density of TfR on EBLs decreased along with cell maturation. The density of TfR was negatively correlated with hemoglobin concentration (r＝－0.76), but SIGs showed no significant correlation with TfR density. In a patint with RARS, there was no difference in TfR density between ringed and non-ringed sideroblasts. By contrast, in a patient with AL, the TfR density of EBLs with morphological changes in nucleus was lower than that of normal EBLs. These findings suggest that the regulation mechanism of TfR in MDS was similar to normal subjects in cell maturation, hemogulobin concentration and SIGs, leaving the question why EBLs in MDS contain numerous SIGs in future. en-copyright= kn-copyright= en-aut-name=TsuyunoRitsurou en-aut-sei=Tsuyuno en-aut-mei=Ritsurou kn-aut-name=露野理津朗 kn-aut-sei=露野 kn-aut-mei=理津朗 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=transferrin receptor kn-keyword=transferrin receptor en-keyword=hemoglobin kn-keyword=hemoglobin en-keyword=stainable iron granule kn-keyword=stainable iron granule en-keyword=myelodysplastic syndrome kn-keyword=myelodysplastic syndrome en-keyword=acute leukemia kn-keyword=acute leukemia END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1023 end-page=1032 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effects of ferric citrate or hyperoxygenation on guanidino compounds in mouse organs kn-title=クエン酸鉄投与及び純酸素負荷マウスのグアニジノ化合物の変動に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The guanidino compounds in various mouse organs after i.p. administration of ferric citrate(Fe) and after inhalation of pure oxygen(O(2)) were studied.

This finding suggested that the reactive oxygen species(O(2)(-), H(2)O(2), ・OH) were most effective there, because oxygen consumpution in the brain was much more than in the other organs. en-copyright= kn-copyright= en-aut-name=WatanabeSeigo en-aut-sei=Watanabe en-aut-mei=Seigo kn-aut-name=渡邊省吾 kn-aut-sei=渡邊 kn-aut-mei=省吾 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属分子細胞医学研究施設神経情報学部門 en-keyword=hyperoxygenation kn-keyword=hyperoxygenation en-keyword=iron ion kn-keyword=iron ion en-keyword=guanidino compounds kn-keyword=guanidino compounds en-keyword=methylganidine kn-keyword=methylganidine en-keyword=free radicals kn-keyword=free radicals END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=1-2 article-no= start-page=137 end-page=144 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estrogen binding capacity in cytosol fraction of human uterine cervix : effect of estrogen and anti-estrogens kn-title=ヒト子宮頸部組織における細胞質分画エストロゲン結合能とそれに影響する因子について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The estrogen binding activity in the human uterine cervix was measured, and the effect of natural and synthesized steroids on the activities was determined. To assay the estrogen binding activity, the asmple was incubated with 10nM [(3)H] estradiol-17β at 30℃ for 2 hours. Then dextran-coated charcoal (DCC) was added to a final concentration of 0.5% to separate bound/free (B/F) estradiol. Estrogen binding activity was determined by subtracting the activity found in the heated sample from the corresponding activity in the untreated sample. For this purpose it was found appropriate to heat the sample at 40℃ for 60 minutes. The dissociation constant obtained from the Scatchard plot analysis was : kd=2.0×10(-9)M. A variety of steroids at the same molar concentration (1.0 μM) were added to the sample to determine their effects on the estrogen binding activity. For binding with [(3)H] estradiol-17β, the synthetic estrogens were strongly inhibitory, the anti-estrogen agents were strong-ly to moderately inhibitory. Dannazol, which has been used for the treatment of en-dometriosis, was found to be as effective as androgens. All of those inhibitory effects occur-red in a non-competitive manner. en-copyright= kn-copyright= en-aut-name=KobayashiShunzo en-aut-sei=Kobayashi en-aut-mei=Shunzo kn-aut-name=小林俊三 kn-aut-sei=小林 kn-aut-mei=俊三 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部産科婦人科学教室 en-keyword=uterine cervix kn-keyword=uterine cervix en-keyword=estrogen receptor inhibition kn-keyword=estrogen receptor inhibition END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=841 end-page=857 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental study on the hepatic effects of sevoflurane anesthesia kn-title=セボフルレン麻酔の肝に及ぼす影響に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The hepatic effects of sevoflurane administered under different inspiratory oxygen concentrations were examined.

The rats administered sevoflurane under 21% oxygen were used as the control. The amount of microsomal protein, the content and activity of hepatic microsomal enzymes, and the amount of enzymes released from the liver cells (GPT, OCT) of each group of rats were measured for 7 days after these procedures. The content of cytochrome P-450 and the activity of aminopyrine demethylation and aniline dehydration were decreased significantly to about 58%, 43% and 40% that of the control, respectively. Furthermore the plasma level of GPT and OCT was elevated to 1,107±620 IU/L and 422±270 IU/L respectively soon after sevoflurane anesthesia only in the group of rats administered sevoflurane under a 10% oxygen concentration. In this study, severe damage to the liver of the rats was observed after sevoflurane anesthesia under 10% oxygen following enzyme induction and fasting. en-copyright= kn-copyright= en-aut-name=OkadaNaoki en-aut-sei=Okada en-aut-mei=Naoki kn-aut-name=岡田尚起 kn-aut-sei=岡田 kn-aut-mei=尚起 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=セボフルレン麻酔 kn-keyword=セボフルレン麻酔 en-keyword=吸入酸素濃度 kn-keyword=吸入酸素濃度 en-keyword=チトクローム　P-450 kn-keyword=チトクローム　P-450 en-keyword=肝障害 kn-keyword=肝障害 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=1-2 article-no= start-page=75 end-page=82 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of immunosuppressive substance against the potency of natural human tumor necrosis factor as biological response modifier kn-title=Biological response modifier としての Tumor necrosis fator の効果に対する Immunosuppressive substance の作用の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=TNF is a cytokine with the activity of a BRM (biological response modifier). TNF-α and TNF-β enhanced NK activity of peripheral blood mononucleocytes of a normal donor, but not in a cancer patient. ISS, a glocoprotein extracted from the ascitic fluid of a colon cancer patient with immunosuppressive properties, ia also detected in large quantities in the serum of cancer patients. NK activity of a normal donor which was in an immunosuppressive state by the administration of ISS was not affected by treatment of TNF-α or TNF-β, but the suppressed NK activity was improved by the combination of TNF with IFN-α or IFN-γ. On the other hand, NK activity of a cancer patient treated with anti-IS antiserum which was obtained from serum of rabbit immunized by ISS was enhanced by both TNFs. These findings suggest that ISS suppresses the effect of TNFs on NK activity. Furthermore, the effect of TNF as a BRM is inhibited in cancer patients due to the high dose of ISS in the serum, and that the combination of TNF with other cytokines, such as IFN, is more effective than the single use of TNF, clinically. en-copyright= kn-copyright= en-aut-name=YasuiYoshimasa en-aut-sei=Yasui en-aut-mei=Yoshimasa kn-aut-name=安井義政 kn-aut-sei=安井 kn-aut-mei=義政 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=biological response modifier (BRM) kn-keyword=biological response modifier (BRM) en-keyword=tumor necrosis fator (TNF) kn-keyword=tumor necrosis fator (TNF) en-keyword=immunosuppressive substance (IS 物質) kn-keyword=immunosuppressive substance (IS 物質) en-keyword=natural killer (NK) 活性 kn-keyword=natural killer (NK) 活性 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=813 end-page=821 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on pathogenesis in iron deficiency anemia Part 2.

However, iron hyper-excretion has not been reported except in the cases of bleeding. Previously, we found increased iron excretion in the urine in patients with iron-losing anemia, such as idiopathic hypochromic anemia. To examine the relationship between iron excretion and anemia, puromycin aminonucleoside (PA) was administered in rats to induce anemia. In such rats, considerable amounts of iron were continuously excreted in the urine and the animals became anemic. However, the anemia in this model was normocytic and normochromic, and the liver iron content was reversely increased. In conclusion, PA administration in rats induces not only iron deficiency as hyper-excretion but also abnormalities of iron metabolism as indicated by the other pathological findings, such as inflammatory change and renal failure. en-copyright= kn-copyright= en-aut-name=NakanishiNorihiko en-aut-sei=Nakanishi en-aut-mei=Norihiko kn-aut-name=中西徳彦 kn-aut-sei=中西 kn-aut-mei=徳彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=iron deficiency anemia kn-keyword=iron deficiency anemia en-keyword=iron-losing anemia kn-keyword=iron-losing anemia en-keyword=puromycin aminonucleoside kn-keyword=puromycin aminonucleoside END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=803 end-page=811 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the pathogenesis in iron deficiency anemia Part 1.

To determine the relevance of urinary iron excretion to clinical factors other than iron metabolism, 15 clinical parameters were evaluated. The serum creatinine level was positively and the serum albumin level was negatively correlated with urinary iron excretion, showing coefficients of r＝0.97,－0.86 respectively, and suggesting a relationship between urinary iron excretion and subclinical abnormalities of kidney function. In experimental studies, the relation of urinary iron excretion to the renal function was examined by administration of iron in various forms to rats. Only saccharated iron oxide was excreted; chondroitin sulfate Fe, Tf-Fe and ferric chloride were not excreted in the urine. Then, iron excretion was examined in iron deficient, iron overloaded and puromycin aminonucleoside (PA)-treated animals. Iron deficient rats did not show any change in urinary iron excretion compared to the controls. Urinary iron excretion was increased in iron overloaded rats, and was further increased in the PA-treated group. These findings suggest that the subclinical abnormality in kidney function leads to the increased urinary iron excretion as a possible factor in the pathogenesis of relapsisg iron deficiency. en-copyright= kn-copyright= en-aut-name=NakanishiNorihiko en-aut-sei=Nakanishi en-aut-mei=Norihiko kn-aut-name=中西徳彦 kn-aut-sei=中西 kn-aut-mei=徳彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=iron deficiency anemia kn-keyword=iron deficiency anemia en-keyword=urinary iron excretion kn-keyword=urinary iron excretion END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=821 end-page=832 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Brain tissue leukotrienes in cerebral ischemia and effect of inhibitor of SRS-A release on postischemic cerebral edema kn-title=虚血性脳浮腫に及ぼすロイコトリエンの影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arachidonic acid metabolites are postulated to play a role in the pathogenesis of cerebral ischemia. To examine the development of lipoxygenase metabolites of arachidonic acid in cerebral ischemia, we measured the concentration of leukotriene C4 in the gerbil forebrain following ischemia, and pretreated several animals with cyclooxygenase and lipoxygenase inhibitors. The leukotriene C4 concentration was significantly increased 1 hour after transient ischemia and cerebral edema. The incerase in the concentration of leukotriene metabolites was significantly suppressed by preteratment with the lipoxygenase inhibitors except for the cyclooxygenase inhibitor and phospholipase A2 inhibitor. Intracerebral cerebral injection of leukotriene C4 produced local intracerebral edema. Cycloxygenase inhibition may result in increased substrate availability for the lipoxygenase system. Studies of such an interaction help elucidate the pharmacological modification of detrimental vascular changes after transient cerebral ischemia. en-copyright= kn-copyright= en-aut-name=TakasugiNoriko en-aut-sei=Takasugi en-aut-mei=Noriko kn-aut-name=高杉能理子 kn-aut-sei=高杉 kn-aut-mei=能理子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=leukotrienes kn-keyword=leukotrienes en-keyword=lipoxygenase kn-keyword=lipoxygenase en-keyword=ischemia kn-keyword=ischemia en-keyword=gerbil kn-keyword=gerbil END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=791 end-page=801 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 2.

Such cell infiltration seems to be induced by the eosinophil chemotactic factor (ECF). PAF and IL-5 are potent chemoattractants and activators for eosinophils. To evaluate the reactivity of eosinophils in asthmatics under various conditions, the migratory function of eosinophils to PAF and IL-5 was investigated by the modified Boyden chamber method. Eosinophils of asthmatics were highly purified using a flow cytometric method previously reported. The migratory response of the eosinophils of asthmatics was greater than that of healthy suljects. Eosinophils from atopic asthmatics showed a higher response to PAF than those from non-atopic asthmatics. Eosinophils in the attack stage showed a higher response than those in the non-attack stage. Hypodense eosinophils showed an increased migratory response. The migratory response was correlated to the serum concentration of ECP and blood eosinophil count. These findings suggest that the reactivity of eosinophils is heterogenous and relates to the degree of eosinophilia, and that IL-5 as well as PAF plays an important role in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Eosinophil migratory response kn-keyword=Eosinophil migratory response en-keyword=Platelet-activating factor kn-keyword=Platelet-activating factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 en-keyword=Eosinophil heterogeneity kn-keyword=Eosinophil heterogeneity END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=763 end-page=775 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the role of neutrophils in intractable asthma Part 1.

The production of leukotrienes (LTs) and superoxide stimulated by the calcium ionophores (CaI) from neutrophil-rich fraction of 29 intractable, 70 non-intractable asthmatics and 18 healthy subjects was examined by high performance liquid chromatography and a cytochrome C reduction method. Significantly larger amounts of LTC(4) and LTB(4) were produced by CaI in the neutrophil-rich fraction from asthematics, than in that from the healthy subjects (p<0.01). Moreover, a significantly larger amounts of LTC(4) was producted in the fraction obtained from the intractable asthmatics than in that from the non-intractable asthmatics (p<0.05). However, there was no significant difference in LTB(4) production between the two groups of asthmatics. The production of superoxide by concanavalin A was significantly increased in the neutrophil-rich fraction from prednisolone-within-10mg-dependent asthmatics than in those from prednisolone-over-10mg-dependent patients (p<0.01). There were correlations between the LTC(4) and LTB(4) production, and also between LTB(4) and superoxide production. LTs and superoxide released from inflammatory cells, especially neutrophils, may play an important role in the pathgenesis of intractable asthma. en-copyright= kn-copyright= en-aut-name=ShimizuIkki en-aut-sei=Shimizu en-aut-mei=Ikki kn-aut-name=清水一紀 kn-aut-sei=清水 kn-aut-mei=一紀 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=難治性喘息 kn-keyword=難治性喘息 en-keyword=好中球 kn-keyword=好中球 en-keyword=ロイコトリエン kn-keyword=ロイコトリエン en-keyword=スーパーオキサイド kn-keyword=スーパーオキサイド END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=779 end-page=789 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 1.

The eosinophil chemotactic factor (ECF) derived from mononuclear cells has been reported to have some effect on the cell infiltration, and interleukin-5 (IL-5), a lymphokine derived from T lymphocytes, to be a factor related to growth, chemotaxis and activation for eosinophils. Lymphocytes accumulated in the bronchoalveolar lavage fluids of non-atopic and severe asthmatics have been shown to be highly responsive to Candida antigen, and high ECF production was observed in non-atopic and severe asthmatics by measurement of ECF activity in the supernatant of peripheral blood mononuclear cells cultured with Candida antigen. In this report, the molecular weight by gel filtration and inhibition test using anti-murine IL-5 antibody were studied to characterize the lymphocyte-derived ECF. Gel filtration analysis of the ECF indicated a molecular weight of 20,000 to 65,000 Da with a peak of activity around 40,000 to 50,000 Da. The ECF activity was reduced by incubation with anti-murine IL-5 antibody, which suggests that the supernatant contains IL-5. ECF from mononuclear cells, containing IL-5, may play an important role in the pathogenesis of eosinophil infiltration in non-atopic and severe asthmatics. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Candida antigen Eosinophil chemotactic factor kn-keyword=Candida antigen Eosinophil chemotactic factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=735 end-page=746 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the mechanism and treatment of intractable asthma Part 2.

In this study, to clarify the action mechanism of OKY-046 and the relationship between TXA(2) and prostaglandin E(2) (PGE(2)) in cell-mediated allergy, the effect of the TXA(2) receptor antagonist (AA-2414), TXA2 analogue (STA(2)) and PGE(2) for peripheral blood mononuclear cells in adult intractable asthmatics was studied. OKY-046 significantly suppressed TXB(2) production and increased PGE(2) production from the peripheral blood mononuclear cells stimulated by PHA and Candida antigen, but AA-2414 had no effect. AA-2414 suppressed lymphocyte blastgenesis, but did not suppress significantly interleukin-2 (IL-2) or neutrophil chemotactic factor (NCF) production. Furthermore, STA(2) increased lymphocyte blastgenesis stimulated by Candida antigen partially, but not dose-dependently. On the other hand, PGE(2) suppressed significantly lymphocyte blastgenesis and IL-2 and NCF production in a dose-dependent manner. These findings suggest that the action mechanism of OKY-046 is a suppressive effect of cell-mediated allergy, and that TXA(2) and PGE(2) play an important role in the mechanism of intractable asthma. en-copyright= kn-copyright= en-aut-name=KanehiroArihiko en-aut-sei=Kanehiro en-aut-mei=Arihiko kn-aut-name=金廣有彦 kn-aut-sei=金廣 kn-aut-mei=有彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Intractable asthma kn-keyword=Intractable asthma en-keyword=thromboxane A(2) kn-keyword=thromboxane A(2) en-keyword=prostaglandin E(2) kn-keyword=prostaglandin E(2) en-keyword=thromboxane A(2) synthetase inhibitor (OKY-046) kn-keyword=thromboxane A(2) synthetase inhibitor (OKY-046) en-keyword=thromboxane A(2) receptor antagonist (AA-2414) kn-keyword=thromboxane A(2) receptor antagonist (AA-2414) END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5-6 article-no= start-page=629 end-page=639 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of administration of inorganic fluorine on renal function in the rabbits kn-title=無機フッ素の腎に及ぼす影響に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=It was previously reported that the elevation of inorganic fluorine level in plasma after inkalation of methoxyflurane causes acute renal failure. This study investigated whether the peak concentration or the duration of the inorganic fluorine is responsible for the real failure. Continuous infusion (5 millimols/liter and 10 millimols/liter) or a single intravenous bolus injection (720 millimols/liter) of sodium fluoride solution was adminstered to rabbits. The plasma concentration and the duration of the plasma fluorine was measured. There were no signs of pathological or biochemical changes that suggested renal failure when the peak plasma concentration was less than 50 millimols/liter for over 4 hours (5 millimols/liter, 24 hours), or whether peak concentration of plasma inorganic fliorine was over 50 millimols/liter for less than 4 hours (720 millimols/liter, intravenous bolus). However when 10 millimols/liter of sodium fluoride solution was administered at a speed of 10 milliliters/hour for 24 hours, the rabbits showed a peak plasma inorganic fluorine concentration over 50 micromols/liter for more than 4 hours and signs of renal failure developed ata plasma concentration of 65.8 micromols/liter 24 hours after the beginning of infusion. renal failure was mainly inthe form of edema of the tubular cells in both the cortex and medulla and abnormal biochemical changes (blood urea nitrogen 55.8±12.5 milligrams/deciliter, plasma creatinine 1.2±0.1 milligrams/deciliter). Inorganic fluorine can cause renal changes when its paek plasma concentration reaches more than 50 micromols/liter and lasts for more than 4 hours. en-copyright= kn-copyright= en-aut-name=YamamotoAtsuya en-aut-sei=Yamamoto en-aut-mei=Atsuya kn-aut-name=山本敦也 kn-aut-sei=山本 kn-aut-mei=敦也 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=無機フッ素 kn-keyword=無機フッ素 en-keyword=腎障害 kn-keyword=腎障害 en-keyword=揮発性吸入麻酔薬 kn-keyword=揮発性吸入麻酔薬 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=769 end-page=778 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Striatal extracellular levels of dopamine and its metabolites during kainate-induced limbic seizures in freely-moving rats measured by brain microdialysis kn-title=カイニン酸誘発けいれんにおける細胞外ドパミン量の経時的変化―脳内微小透析法を用いた実験的研究― en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the role of brain dopaminergic systems in epilepsy, striatal extracellular levels of dopamins (DA) and its metabolites (3,4-dihydroxyphenylacetic acid : DOPAC and homovanillic acid : HVA) were measured during kainate-induced limbic seizures in freely-moving rats, using brain microdialysis. DA and its metabolites were measured by high performance liquid chromatography. Systemic injection of kainate (10mg/㎏, i. p.), which caused stable limbic seizures, significantly decreased the levels of DA and its metabolites. Intrahippocampal injection of kainae (2.5nmol), which also caused limbic seizures, significantly decreased only the DA levels, while DOPAC and HVA levels were unchanged. Similar to the results of the systemic injectjon, intrastriatal perfusion of kainate (10(-2) or 10(-6) M) significantly decreased the levels of DA, DOPAC and HVA in a dose-dependent manner. These findings indicate that, during kainate-induced limbic seizures, DA release was significantly reduced in the striatum. In conclusion, the hypofunction of striatal dopaminergic systems is related to the initiation and progress in epileptic seizures. en-copyright= kn-copyright= en-aut-name=OhnishiMasaru en-aut-sei=Ohnishi en-aut-mei=Masaru kn-aut-name=大西勝 kn-aut-sei=大西 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=kainate kn-keyword=kainate en-keyword=brain microdialysis kn-keyword=brain microdialysis en-keyword=dopamine kn-keyword=dopamine en-keyword=striatum kn-keyword=striatum en-keyword=epilepsy kn-keyword=epilepsy END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=759 end-page=768 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis on the mechanism of the temperature-sensitive melibiose metabolism in Lactobacillus plantarum kn-title=Lactobacillus plantarum におけるメリビオース代謝の高温感受性機構の解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=L. plantarum can grow on melibiose when incubated at 30℃ but not when incubated at 37℃. In this study, the temperature sensitivity of melibiose metabolism was analyzed. The melibiose metabolism seemed to consist of the melibiose transport system and hydrolyzing enzyme, α-galactosidase. α-Galactosidase was induced with melibiose at 30℃ but not at 37℃. This enzyme induced at 30℃ hydrolyzed colorimetric substrate, α-ONPG at 30℃ and 37℃. On the other hand, lactose induced α-galactosidase at both temperatures. These findings suggested that the temperature sensitivity of melibiose metabolism was not due to the induction and/or function of α-galactosidase. Thus, the effect of temperature on induction and function of the melibiose transport system was examined. Cells grown on melibiose at 30℃ exhibited the rapid uptake of [(3)H] -melibiose at 30℃ and 37℃, while [(3)H] -melibiose was not taken up by the cells grown at 37℃. The induction of the melibiose transport system seemed to be temperature-sensitive because the transport system was not inactivated by exposure of the cells to 37℃ for 3 hours. In conclusion, the temperature sensitivity of melibiose metabolism was attributed to the temperature sensitivity of the induction of melibiose transport system. en-copyright= kn-copyright= en-aut-name=TamuraChiyuki en-aut-sei=Tamura en-aut-mei=Chiyuki kn-aut-name=田村千幸 kn-aut-sei=田村 kn-aut-mei=千幸 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部細菌学教室 en-keyword=Lactobacillus plantarum kn-keyword=Lactobacillus plantarum en-keyword=メリビオース kn-keyword=メリビオース en-keyword=高温感受性 kn-keyword=高温感受性 en-keyword=α-ガラクトシダーゼ kn-keyword=α-ガラクトシダーゼ en-keyword=メリビオース輸送系 kn-keyword=メリビオース輸送系 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=749 end-page=757 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Role of sigma sites in the modulation of neuroleptics-induced dystonia in rats kn-title=抗精神病薬によるジストニアの発現機序に関する実験的研究―σ (sigma) sites の関与について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent findings have suggested that neuroleptics exhibit a strong affinity for not only dopamine receptors, but also the sigma sites. Therefore, some clinical or adverse effects of neuroleptics may be due to their action on the sigma sites. This study showed that intrarubral microinjection of 1,3-di-o-tolylguanidine (DTG) or (＋) -3- (3-hydroxyphenyl) -N-1-propyl) piperidine, sigma ligands, and several neuroleptics such as haloperidol caused dystonic reactions in rats resembling tha acute dystonic reaction in humans. The intensity and duration of the dystonia induced by these drugs showed a correlation with their affinities for the sigma sites. These findings raise the possibility that the acute dystonic reaction, one of the motor side effects of neuroleptics, might be mediated via the sigma sites. On the other hand, BMY 14802, an atypical neuroleptic, never caused dystonia after intrarubral microinjection. Furthermore, BMY 14802 still inhibited the dystonia induced by intrarubral microinjection of DTG. This reduction in DTG-induced dystonia by BMY 14802 may result its direct inhibitory effects against DTG at the sites, because BMY 14802 possesses potent sigma affinty. These findings imply that sigma ligands may be divided into two categories, dystonia-reinforcing and -reducing groups. Application of this theory should lead to the elucidation of the mechanism of neuroleptics-induced dystonia and other motor side effects. en-copyright= kn-copyright= en-aut-name=OkumuraKazuya en-aut-sei=Okumura en-aut-mei=Kazuya kn-aut-name=奥村一哉 kn-aut-sei=奥村 kn-aut-mei=一哉 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=sigma sites kn-keyword=sigma sites en-keyword=dystonia kn-keyword=dystonia en-keyword=1, 3 -di-o-tolylguanidine (DTG) kn-keyword=1, 3 -di-o-tolylguanidine (DTG) en-keyword=BMY 14802 kn-keyword=BMY 14802 en-keyword=neuroleptics kn-keyword=neuroleptics END
