kn-title=CNGC2 Negatively Regulates Stomatal Closure and Is Not Required for flg22- and H2O2-Induced Guard Cell [Ca2+]cyt Elevation in Arabidopsis thaliana

kn-abstract=In guard cells, cytosolic Ca2+ acts as a second messenger that mediates abscisic acid (ABA)- and pathogen-associated molecular pattern (PAMP)-induced stomatal closure. It was reported that Arabidopsis cyclic nucleotide-gated ion channel 2 (CNGC2) functions as hydrogen peroxide (H2O2)- and PAMP-activated Ca2+-permeable channels at the plasma membrane of mesophyll cells and mediates Ca2+-dependent PAMP-triggered immunity. In this study, we examined the role of CNGC2 in the regulation of stomatal movement because CNGC2 is also expressed in guard cells. We found that stomata of the CNGC2 disruption mutant cngc2-3 are constitutively closed even in the absence of ABA or the flagellar-derived PAMP, flg22. Consistently, leaf temperatures of the cngc2-3 mutant were higher than those of wild-type (WT) plants. The stomatal phenotype of the cngc2-3 mutant was restored by complementation with wild-type CNGC2 under the control of the guard cell preferential promoter, pGC1. Elevation of cytosolic free Ca2+ concentration in guard cells induced by flg22 and H2O2 remained intact in the cngc2-3 mutant. The introduction of the ost1-3 mutation into the cngc2-3 background did not alter the stomatal phenotype. However, the stomatal phenotype of the cngc2-3 mutant was successfully rescued in the double disruption mutant cngc2-3aba2-2. Taken together, these results suggest that CNGC2 negatively regulates stomatal closure response and does not function as flg22– and H2O2-activated Ca2+ channels in guard cells. Though CNGC2 is responsive for H2O2- and flg22-induced [Ca2+]cyt elevation in mesophyll cells, the involvement of CNGC2 in the response to H2O2 and flg22 in guard cells is questionable.

kn-title=Carnosol, a Rosemary Ingredient Discovered in a Screen for Inhibitors of SARM1-NAD+ Cleavage Activity, Ameliorates Symptoms of Peripheral Neuropathy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Sterile alpha and Toll/interleukin receptor motif-containing protein 1 (SARM1) is a nicotinamide adenine dinucleotide (NAD+) hydrolase involved in axonal degeneration and neuronal cell death. SARM1 plays a pivotal role in triggering the neurodegenerative processes that underlie peripheral neuropathies, traumatic brain injury, and neurodegenerative diseases. Importantly, SARM1 knockdown or knockout prevents the degeneration; as a result, SARM1 has been attracting attention as a potent therapeutic target. In recent years, the development of several SARM1 inhibitors derived from synthetic chemical compounds has been reported; however, no dietary ingredients with SARM1 inhibitory activity have been identified. Therefore, we here focused on dietary ingredients and found that carnosol, an antioxidant contained in rosemary, inhibits the NAD+-cleavage activity of SARM1. Purified carnosol inhibited the enzymatic activity of SARM1 and suppressed neurite degeneration and cell death induced by the anti-cancer medicine vincristine (VCR). Carnosol also inhibited VCR-induced hyperalgesia symptoms, suppressed the loss of intra-epidermal nerve fibers in vivo, and reduced the blood fluid level of phosphorylated neurofilament-H caused by an axonal degeneration event. These results indicate that carnosol has a neuroprotective effect via SARM1 inhibition in addition to its previously known antioxidant effect via NF-E2-related factor 2 and thus suppresses neurotoxin-induced peripheral neuropathy.

kn-title=Fraglide-1 from traditional Chinese aromatic vinegar: A natural AhR antagonist for atopic dermatitis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Traditional Chinese Zhenjiang aromatic vinegar (Kozu) contains Fraglide-1 (FG1), a bioactive lactone with demonstrated peroxisome proliferator-activated receptor gamma (PPARγ) agonist and antioxidant activities. This study explored FG1's novel ability to antagonize the aryl hydrocarbon receptor (AhR) signaling pathway, which regulates artemin expression and contributes to itching and inflammation in atopic dermatitis. Through molecular docking simulations and cell-based assays in human keratinocytes, we demonstrated FG1's potent antagonistic activity against AhR signaling. FG1 effectively suppressed FICZ-induced inflammatory responses, including artemin expression, with potency (half maximal inhibitory concentration, IC50 = 5.1 μM) comparable to the synthetic antagonist StemRegenin 1 (SR1) while demonstrating a superior safety profile (median lethal concentration, LC50 > 100 μM vs. 27.5 μM for SR1). These findings expand our understanding of bioactive compounds from traditional fermented foods and their regulatory effects on AhR signaling, providing a foundation for future studies on FG1's role in modulating skin inflammation.

kn-title=Quercetin Attenuates Acetaldehyde-Induced Cytotoxicity via the Heme Oxygenase-1-Dependent Antioxidant Mechanism in Hepatocytes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=It is still unclear whether or how quercetin influences the toxic events induced by acetaldehyde in hepatocytes, though quercetin has been reported to mitigate alcohol-induced mouse liver injury. In this study, we evaluated the modulating effect of quercetin on the cytotoxicity induced by acetaldehyde in mouse hepatoma Hepa1c1c7 cells, the frequently used cellular hepatocyte model. The pretreatment with quercetin significantly inhibited the cytotoxicity induced by acetaldehyde. The treatment with quercetin itself had an ability to enhance the total ALDH activity, as well as the ALDH1A1 and ALDH3A1 gene expressions. The acetaldehyde treatment significantly enhanced the intracellular reactive oxygen species (ROS) level, whereas the quercetin pretreatment dose-dependently inhibited it. Accordingly, the treatment with quercetin itself significantly up-regulated the representative intracellular antioxidant-related gene expressions, including heme oxygenase-1 (HO-1), glutamate-cysteine ligase, catalytic subunit (GCLC), and cystine/glutamate exchanger (xCT), that coincided with the enhancement of the total intracellular glutathione (GSH) level. Tin protoporphyrin IX (SNPP), a typical HO-1 inhibitor, restored the quercetin-induced reduction in the intracellular ROS level, whereas buthionine sulphoximine, a representative GSH biosynthesis inhibitor, did not. SNPP also cancelled the quercetin-induced cytoprotection against acetaldehyde. These results suggest that the low-molecular-weight antioxidants produced by the HO-1 enzymatic reaction are mainly attributable to quercetin-induced cytoprotection.

kn-title=Lentil adaptation to drought stress: response, tolerance, and breeding approaches
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Lentil (Lens culinaris Medik.) is a cool season legume crop that plays vital roles in food and nutritional security, mostly in the least developed countries. Lentil is often cultivated in dry and semi-dry regions, where the primary abiotic factor is drought, which negatively impacts lentil growth and development, resulting in a reduction of yield. To withstand drought-induced multiple negative effects, lentil plants evolved a variety of adaptation strategies that can be classified within three broad categories of drought tolerance mechanisms (i.e., escape, avoidance, and tolerance). Lentil adapts to drought by the modulation of various traits in the root system, leaf architecture, canopy structure, branching, anatomical features, and flowering process. Furthermore, the activation of certain defensive biochemical pathways as well as the regulation of gene functions contributes to lentil drought tolerance. Plant breeders typically employ conventional and mutational breeding approaches to develop lentil varieties that can withstand drought effects; however, little progress has been made in developing drought-tolerant lentil varieties using genomics-assisted technologies. This review highlights the current understanding of morpho-physiological, biochemical, and molecular mechanisms of lentil adaptation to drought stress. We also discuss the potential application of omics-assisted breeding approaches to develop lentil varieties with superior drought tolerance traits.

kn-abstract=Compiling evidence has indicated that S100A11 expression at high levels is closely associated with various cancer species. Consistent with the results reported elsewhere, we have also revealed that S100A11 is highly expressed in squamous cell carcinoma, mesothelioma, and pancreatic cancers and plays a crucial role in cancer progression when secreted into extracellular fluid. Those studies are all focused on the extracellular role of S100A11. However, most of S100A11 is still present within cancer cells, although the intracellular role of S100A11 in cancer cells has not been fully elucidated. Thus, we aimed to investigate S100A11 functions within cancer cells, primarily focusing on colorectal cancer cells, whose S100A11 is abundantly present in cells and still poorly studied cancer for the protein. Our efforts revealed that overexpression of S100A11 promotes proliferation and migration, and downregulation inversely dampens those cancer behaviors. To clarify how intracellular S100A11 aids cancer cell activation, we tried to identify S100A11 binding proteins, resulting in novel binding partners in the inner membrane, many of which are desmosome proteins. Our molecular approach defined that S100A11 regulates the expression level of DSG1, a component protein of desmosome, by which S100A11 activates the TCF pathway via promoting nuclear translocation of γ-catenin from the desmosome. The identified new pathway greatly helps to comprehend S100A11’s nature in colorectal cancers and others.

kn-title=Dissection of the signal transduction machinery responsible for the lysyl oxidase-like 4-mediated increase in invasive motility in triple-negative breast cancer cells: mechanistic insight into the integrin-β1-NF-κB-MMP9 axis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Triple-negative breast cancer (TNBC) cells are a highly formidable cancer to treat. Nonetheless, by continued investigation into the molecular biology underlying the complex regulation of TNBC cell activity, vulnerabilities can be exposed as potential therapeutic targets at the molecular level. We previously revealed that lysyl oxidase-like 4 (LOXL4) promotes the invasiveness of TNBC cells via cell surface annexin A2 as a novel binding substrate of LOXL4, which promotes the abundant localization of integrin-beta 1 at the cancer plasma membrane. However, it has yet to be uncovered how the LOXL4-mediated abundance of integrin-beta 1 hastens the invasive outgrowth of TNBC cells at the molecular level.
Methods LOXL4-overexpressing stable clones were established from MDA-MB-231 cells and subjected to molecular analyses, real-time qPCR and zymography to clarify their invasiveness, signal transduction, and matrix metalloprotease (MMP) activity, respectively.
Results Our results show that LOXL4 potently promotes the induction of matrix metalloprotease 9 (MMP9) via activation of nuclear factor-kappa B (NF-kappa B). Our molecular analysis revealed that TNF receptor-associated factor 4 (TRAF4) and TGF-beta activated kinase 1 (TAK1) were required for the activation of NF-kappa B through I kappa beta kinase kinase (IKK alpha/beta) phosphorylation.
Conclusion Our results demonstrate that the newly identified LOXL4-mediated axis, integrin-beta 1-TRAF4-TAK1-IKK alpha/beta-I kappa beta alpha-NF-kappa B-MMP9, is crucial for TNBC cell invasiveness.

kn-title=Enhancing effect of the coexisting alpha-tocopherol on quercetin absorption and metabolism
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this study is to investigate the modulating effect of coexisting food components on the absorption and metabolism of quercetin and blood plasma antioxidant potentials. The combination of quercetin with α-tocopherol (αT), cellulose, or a commercially available vegetable beverage containing αT and dietary fiber was orally administered to mice. Compared to the single administration of quercetin aglycone, the coadministration of αT with quercetin significantly increased the plasma quercetin concentration at 0.5 h, whereas the combination of quercetin and cellulose decreased it. Interestingly, the administration of quercetin mixed with the vegetable beverage showed no significant change in the quercetin concentration in the mice plasma. The treatment of the cells with the blood plasma after the coadministration of αT with quercetin significantly upregulated the gene expression of the antioxidant enzyme (heme oxygenase-1), whereas the quercetin and cellulose combination did not. In the plasma of the quercetin-administered mice, eight types of quercetin metabolites were detected, and their quantities were affected by the combination with αT. The potentials of the heme oxygenase-1 gene expression by these metabolites were very limited, although several metabolites showed radical scavenging activities comparable to aglycone in the in vitro assays. These results suggested that the combination of αT potentiates the quercetin absorption and metabolism and thus the plasma antioxidant potentials, at least in part, by the quantitative changes in the quercetin metabolites.

kn-title=Novel extracellular role of REIC/Dkk-3 protein in PD-L1 regulation in cancer cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The adenovirus-REIC/Dkk-3 expression vector (Ad-REIC) has been the focus of numerous clinical studies due to its potential for the quenching of cancers. The cancer-suppressing mechanisms of the REIC/DKK-3 gene depend on multiple pathways that exert both direct and indirect effects on cancers. The direct effect is triggered by REIC/Dkk-3-mediated ER stress that causes cancer-selective apoptosis, and the indirect effect can be classified in two ways: (i) induction, by Ad-REIC-mis-infected cancer-associated fibroblasts, of the production of IL-7, an important activator of T cells and NK cells, and (ii) promotion, by the secretory REIC/Dkk-3 protein, of dendritic cell polarization from monocytes. These unique features allow Ad-REIC to exert effective and selective cancer-preventative effects in the manner of an anticancer vaccine. However, the question of how the REIC/Dkk-3 protein leverages anticancer immunity has remained to be answered. We herein report a novel function of the extracellular REIC/Dkk-3—namely, regulation of an immune checkpoint via modulation of PD-L1 on the cancer-cell surface. First, we identified novel interactions of REIC/Dkk-3 with the membrane proteins C5aR, CXCR2, CXCR6, and CMTM6. These proteins all functioned to stabilize PD-L1 on the cell surface. Due to the dominant expression of CMTM6 among the proteins in cancer cells, we next focused on CMTM6 and observed that REIC/Dkk-3 competed with CMTM6 for PD-L1, thereby liberating PD-L1 from its complexation with CMTM6. The released PD-L1 immediately underwent endocytosis-mediated degradation. These results will enhance our understanding of not only the physiological nature of the extracellular REIC/Dkk-3 protein but also the Ad-REIC-mediated anticancer effects.

kn-title=Phosphorylated SARM1 is involved in the pathological process of rotenone-induced neurodegeneration

kn-abstract=Sterile alpha and Toll/interleukin receptor motif-containing protein 1 (SARM1) is a NAD+ hydrolase that plays a key role in axonal degeneration and neuronal cell death. We reported that c-Jun N-terminal kinase (JNK) activates SARM1 through phosphorylation at Ser-548. The importance of SARM1 phosphorylation in the pathological process of Parkinson’s disease (PD) has not been determined. We thus conducted the present study by using rotenone (an inducer of PD-like pathology) and neurons derived from induced pluripotent stem cells (iPSCs) from healthy donors and a patient with familial PD PARK2 (FPD2). The results showed that compared to the healthy neurons, FPD2 neurons were more vulnerable to rotenone-induced stress and had higher levels of SARM1 phosphorylation. Similar cellular events were obtained when we used PARK2-knockdown neurons derived from healthy donor iPSCs. These events in both types of PD-model neurons were suppressed in neurons treated with JNK inhibitors, Ca2+-signal inhibitors, or by a SARM1-knockdown procedure. The degenerative events were enhanced in neurons overexpressing wild-type SARM1 and conversely suppressed in neurons overexpressing the SARM1-S548A mutant. We also detected elevated SARM1 phosphorylation in the midbrain of PD-model mice. The results indicate that phosphorylated SARM1 plays an important role in the pathological process of rotenone-induced neurodegeneration.

kn-title=Lysyl oxidase-like 4 promotes the invasiveness of triple-negative breast cancer cells by orchestrating the invasive machinery formed by annexin A2 and S100A11 on the cell surface
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Our earlier research revealed that the secreted lysyl oxidase-like 4 (LOXL4) that is highly elevated in triple-negative breast cancer (TNBC) acts as a catalyst to lock annexin A2 on the cell membrane surface, which accelerates invasive outgrowth of the cancer through the binding of integrin-β1 on the cell surface. However, whether this machinery is subject to the LOXL4-mediated intrusive regulation remains uncertain.
Methods: Cell invasion was assessed using a transwell-based assay, protein–protein interactions by an immunoprecipitation–Western blotting technique and immunocytochemistry, and plasmin activity in the cell membrane by gelatin zymography.
Results: We revealed that cell surface annexin A2 acts as a receptor of plasminogen via interaction with S100A10, a key cell surface annexin A2-binding factor, and S100A11. We found that the cell surface annexin A2/S100A11 complex leads to mature active plasmin from bound plasminogen, which actively stimulates gelatin digestion, followed by increased invasion.
Conclusion: We have refined our understanding of the role of LOXL4 in TNBC cell invasion: namely, LOXL4 mediates the upregulation of annexin A2 at the cell surface, the upregulated annexin 2 binds S100A11 and S100A10, and the resulting annexin A2/S100A11 complex acts as a receptor of plasminogen, readily converting it into active-form plasmin and thereby enhancing invasion.

kn-title=The effect of exogenous dihydroxyacetone and methylglyoxal on growth, anthocyanin accumulation, and the glyoxalase system in Arabidopsis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Dihydroxyacetone (DHA) occurs in wide-ranging organisms, including plants, and can undergo spontaneous conversion to methylglyoxal (MG). While the toxicity of MG to plants is well-known, the toxicity of DHA to plants remains to be elucidated. We investigated the effects of DHA and MG on Arabidopsis. Exogenous DHA at up to 10 mM did not affect the radicle emergence, the expansion of green cotyledons, the seedling growth, or the activity of glyoxalase II, while DHA at 10 mM inhibited the root elongation and increased the activity of glyoxalase I. Exogenous MG at 1.0 mM inhibited these physiological responses and increased both activities. Dihydroxyacetone at 10 mM increased the MG content in the roots. These results indicate that DHA is not so toxic as MG in Arabidopsis seeds and seedlings and suggest that the toxic effect of DHA at high concentrations is attributed to MG accumulation by the conversion to MG.

kn-title=Combined Effect of Salicylic Acid and Proline Mitigates Drought Stress in Rice (Oryza sativa L.) through the Modulation of Physiological Attributes and Antioxidant Enzymes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Salicylic acid (SA) and proline exhibit protective effects against a wide range of stresses. However, the combined impact of SA and proline on rice under drought stress is still unknown. Therefore, we investigated the protective roles of SA and/or proline in conferring drought tolerance in rice. There were eight treatments comprising the control (T1; 95-100% FC), 1.5 mM SA (T2), 2 mM proline (T3), 0.75 mM SA + 1 mM proline (T4), 45-50% FC (T5, drought stress), T5 + 1.5 mM SA (T6), T5 + 2 mM proline (T7), and T5 + 0.75 mM SA + 1 mM proline (T8), and two rice varieties: BRRI dhan66 and BRRI dhan75. Drought stress significantly decreased the plant growth, biomass, yield attributes, photosynthetic rate (Pn), stomatal conductance (gs), transpiration rate (Tr), photosynthetic pigments (chlorophyll and carotenoids content), relative water content (RWC), membrane stability index (MSI), soluble sugar and starch content, and uptake of N, P and K+ in roots and shoots. Drought-induced oxidative stress in the form of increased hydrogen peroxide (H2O2) production and lipid peroxidation (MDA) was observed. The combined application of SA (0.75 mM) + proline (1 mM) was found to be more effective than the single application of either for drought stress mitigation in rice. A combined dose of SA + proline alleviated oxidative stress through boosting antioxidant enzymatic activity in contrast to their separate application. The application of SA + proline also enhanced proline, soluble sugar and starch content, which resulted in the amelioration of osmotic stress. Consequently, the combined application of SA and proline significantly increased the gas exchange characteristics, photosynthetic pigments, RWC, MSI, nutrient uptake, plant growth, biomass and yield of rice. Therefore, the combined application of SA and proline alleviated the detrimental impacts of drought stress more pronouncedly than their separate application did by increasing osmoprotectants, improving nutrient transport, up-regulating antioxidant enzyme activity and inhibiting oxidative stress.

kn-title=STAT1/3 signaling suppresses axon degeneration and neuronal cell death through regulation of NAD+-biosynthetic and consuming enzymes
en-subtitle=

en-abstract=
kn-abstract=Nicotinamide adenine dinucleotide (NAD)+-biosynthetic and consuming enzymes are involved in various intracellular events through the regulation of NAD+ metabolism. Recently, it has become clear that alterations in the expression of NAD+-biosynthetic and consuming enzymes contribute to the axonal stability of neurons. We explored soluble bioactive factor(s) that alter the expression of NAD+-metabolizing enzymes and found that cytokine interferon (IFN)-γ increased the expression of nicotinamide nucleotide adenylyltransferase 2 (NMNAT2), an NAD+-biosynthetic enzyme. IFN-γ activated signal transducers and activators of transcription 1 and 3 (STAT1/3) followed by c-Jun N-terminal kinase (JNK) suppression. As a result, STAT1/3 increased the expression of NMNAT2 at both mRNA and protein levels in a dose- and time-dependent manner and, at the same time, suppressed activation of sterile alpha and Toll/interleukin receptor motif-containing 1 (SARM1), an NAD+-consuming enzyme, and increased intracellular NAD+ levels. We examined the protective effect of STAT1/3 signaling against vincristine-mediated cell injury as a model of chemotherapy-induced peripheral neuropathy (CIPN), in which axonal degeneration is involved in disease progression. We found that IFN-γ-mediated STAT1/3 activation inhibited vincristine-induced downregulation of NMNAT2 and upregulation of SARM1 phosphorylation, resulting in modest suppression of subsequent neurite degradation and cell death. These results indicate that STAT1/3 signaling induces NMNAT2 expression while simultaneously suppressing SARM1 phosphorylation, and that both these actions contribute to suppression of axonal degeneration and cell death.

kn-title=Lysyl oxidase-like 4 exerts an atypical role in breast cancer progression that is dependent on the enzymatic activity that targets the cell-surface annexin A2
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: LOX family members are reported to play pivotal roles in cancer. Unlike their enzymatic activities in collagen cross-linking, their precise cancer functions are unclear. We revealed that LOXL4 is highly upregulated in breast cancer cells, and we thus sought to define an unidentified role of LOXL4 in breast cancer.
Methods: We established the MDA-MB-231 sublines MDA-MB-231-LOXL4 mutCA and -LOXL4 KO, which stably overexpress mutant LOXL4 that loses its catalytic activity and genetically ablates the intrinsic LOXL4 gene, respectively. In vitro and in vivo evaluations of these cells’ activities of cancer outgrowth were conducted by cell-based assays in cultures and an orthotopic xenograft model, respectively. The new target (s) of LOXL4 were explored by the MS/MS analytic approach.
Results: Our in vitro results revealed that both the overexpression of mutCA and the KO of LOXL4 in cells resulted in a marked reduction of cell growth and invasion. Interestingly, the lowered cellular activities observed in the engineered cells were also reflected in the mouse model. We identified a novel binding partner of LOXL4, i.e., annexin A2. LOXL4 catalyzes cell surface annexin A2 to achieve a cross-linked multimerization of annexin A2, which in turn prevents the internalization of integrin β-1, resulting in the locking of integrin β-1 on the cell surface. These events enhance the promotion of cancer cell outgrowth.
Conclusions: LOXL4 has a new role in breast cancer progression that occurs via an interaction with annexin A2 and integrin β-1 on the cell surface.

kn-title=LOXL1 and LOXL4 are novel target genes of the Zn2+-bound form of ZEB1 and play a crucial role in the acceleration of invasive events in triple-negative breast cancer cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: EMT has been proposed to be a crucial early event in cancer metastasis. EMT is rigidly regulated by the action of several EMT-core transcription factors, particularly ZEB1. We previously revealed an unusual role of ZEB1 in the S100A8/A9-mediated metastasis in breast cancer cells that expressed ZEB1 at a significant level and showed that the ZEB1 was activated on the MCAM-downstream pathway upon S100A8/A9 binding. ZEB1 is well known to require Zn2+ for its activation based on the presence of several Zn-finger motifs in the transcription factor. However, how Zn2+-binding works on the pleiotropic role of ZEB1 through cancer progression has not been fully elucidated.
Methods: We established the engineered cells, MDA-MB-231 MutZEB1 (MDA-MutZEB1), that stably express MutZEB1 (Delta Zn). The cells were then evaluated in vitro for their invasion activities. Finally, an RNA-Seq analysis was performed to compare the gene alteration profiles of the established cells comprehensively.
Results: MDA-MutZEB1 showed a significant loss of the EMT, ultimately stalling the invasion. Inclusive analysis of the transcription changes after the expression of MutZEB1 (Delta Zn) in MDA-MB-231 cells revealed the significant downregulation of LOX family genes, which are known to play a critical role in cancer metastasis. We found that LOXL1 and LOXL4 remarkably enhanced cancer invasiveness among the LOX family genes with altered expression.
Conclusions: These findings indicate that ZEB1 potentiates Zn2+-mediated transcription of plural EMT-relevant factors, including LOXL1 and LOXL4, whose upregulation plays a critical role in the invasive dissemination of breast cancer cells.

kn-title=Cycloartenyl Ferulate Is the Predominant Compound in Brown Rice Conferring Cytoprotective Potential against Oxidative Stress-Induced Cytotoxicity
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Since brown rice extract is a rich source of biologically active compounds, the present study is aimed to quantify the major compounds in brown rice and to compare their cytoprotective potential against oxidative stress. The content of the main hydrophobic compounds in brown rice followed the order of cycloartenyl ferulate (CAF) (89.00 +/- 8.07 nmol/g) >> alpha-tocopherol (alpha T) (19.73 +/- 2.28 nmol/g) > gamma-tocotrienol (gamma T3) (18.24 +/- 1.41 nmol/g) > alpha-tocotrienol (alpha T3) (16.02 +/- 1.29 nmol/g) > gamma-tocopherol (gamma T) (3.81 +/- 0.40 nmol/g). However, the percent contribution of CAF to the radical scavenging activity of one gram of whole brown rice was similar to those of alpha T, alpha T3, and gamma T3 because of its weaker antioxidant activity. The CAF pretreatment displayed a significant cytoprotective effect on the hydrogen peroxide-induced cytotoxicity from 10 mu M, which is lower than the minimal concentrations of alpha T and gamma T required for a significant protection. CAF also enhanced the nuclear factor erythroid 2-related factor 2 (Nrf2) nuclear translocation coincided with the enhancement of the heme oxygenase-1 (HO-1) mRNA level. An HO-1 inhibitor, tin protoporphyrin IX (SnPP), significantly impaired the cytoprotection of CAF. The cytoprotective potential of CAF is attributable to its cycloartenyl moiety besides the ferulyl moiety. These results suggested that CAF is the predominant cytoprotector in brown rice against hydrogen peroxide-induced cytotoxicity.

kn-title=Effectiveness of Tactile Warning and Voice Command for Enhancing Safety of Drivers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Safety is impaired when drivers are required to perform main driving task (tracking of own car, distance maintenance between own car and a leading car, and response to target objects) and secondary task simultaneously, for example, responding to target cars on the road while operating in-vehicle equipment. A two-factor (presence or absence of tactile warning by input modality (no secondary task, voice command for a secondary task, and manual input for a secondary task)) within-subject design of ten licensed males was used to investigate how to compensate for safety impairments (decreased performance of a main and a secondary task such as increased tracking error during driving or increased reaction time to target cars on the road). We investigated whether the use of tactile warnings transmitted via left and right thighs for detecting road objects and voice command to operate in-vehicle equipment could compensate for safety impairments such as the increased reaction time to target cars on the road, the increase of detection error of target cars, or increased tracking error in driving. The accuracy and speed of responses to target cars encountered during driving were reduced when a driver was asked to perform the main and the secondary task simultaneously compared to situations performing only the main driving task (tracking, distance maintenance, and response to target cars). The availability of a tactile warning system for road objects compensated for these diminished performance measures, including slower response times and the increased detection error of target cars. Likewise, voice command contributed to enhanced performance of the main driving task such as decrease of tracking error.

kn-abstract=The dissection of the complex multistep process of metastasis exposes vulnerabilities that could be exploited to prevent metastasis. To search for possible factors that favor metastatic outgrowth, we have been focusing on secretory S100A8/A9. A heterodimer complex of the S100A8 and S100A9 proteins, S100A8/A9 functions as a strong chemoattractant, growth factor, and immune suppressor, both promoting the cancer milieu at the cancer-onset site and cultivating remote, premetastatic cancer sites. We previously reported that melanoma cells show lung-tropic metastasis owing to the abundant expression of S100A8/A9 in the lung. In the present study, we addressed the question of why melanoma cells are not metastasized into the brain at significant levels in mice despite the marked induction of S100A8/A9 in the brain. We discovered the presence of plasma histidine-rich glycoprotein (HRG), a brain-metastasis suppression factor against S100A8/A9. Using S100A8/A9 as an affinity ligand, we searched for and purified the binding plasma proteins of S100A8/A9 and identified HRG as the major protein on mass spectrometric analysis. HRG prevents the binding of S100A8/A9 to the B16-BL6 melanoma cell surface via the formation of the S100A8/A9 complex. HRG also inhibited the S100A8/A9-induced migration and invasion of A375 melanoma cells. When we knocked down HRG in mice bearing skin melanoma, metastasis to both the brain and lungs was significantly enhanced. The clinical examination of plasma S100A8/A9 and HRG levels showed that lung cancer patients with brain metastasis had higher S100A8/A9 and lower HRG levels than nonmetastatic patients. These results suggest that the plasma protein HRG strongly protects the brain and lungs from the threat of melanoma metastasis.

kn-title=Sensitivity of PERCLOS70 to Drowsiness Level: Effectiveness of PERCLOS70 to Prevent Crashes Caused by Drowsiness
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=It has been reported that many crashes are caused by drowsiness. Thus, it is critical to predict the occurrence of severe drowsiness that may result in a crash by means of an effective measure. The aim of this study was to investigate whether percentage closure (PERCLOS) of 70% was useful for evaluating drowsiness level of individual drivers and preventing crashes caused by drowsy driving using a driving simulator system. The first experiment measured PERCLOS70 during both aroused and drowsy states in a driving simulator task and investigated how PERCLOS70 changes when a participant fell asleep. In the second experiment, we measured PERCLOS70 and investigated the relation between PERCLOS70 and Karolinska Sleepiness Scale (KSS) ratings during a simulated driving task. The aggregated mean PERCLOS70 was significantly higher when participants fell asleep than when they were aroused. This tendency was also observed for individual participants. The aggregated mean PERCLOS70 was found to be sensitive to changes in KSS scores and increased with increasing KSS score. Linear trend analysis revealed a significant increasing trend for PERCLOS70 as a function of the KSS rating. This tendency was also observed for individual participants. PERCLOS70 was found to be sensitive to the drowsiness level both for data aggregated across all participants and data for individual participants. The main findings of the two experiments reported herein suggest that PERCLOS70 can be used effectively to evaluate drowsiness of individual drivers and prevent crashes caused by drowsy driving.

kn-title=Delayed Evacuation after a Disaster Because of Irrational Prediction of the Future Cumulative Precipitation Time Series under Asymmetry of Information
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigated biased prediction of cumulative precipitation, using a variety of patterns of histories of cumulative precipitation, to explore how such biased prediction could delay evacuation or evacuation orders. The irrationality in predicting the future of cumulative precipitation was examined to obtain insights into the causes of delayed evacuation or evacuation orders using a simulated prediction of future cumulative precipitation based on the cumulative precipitation history. Anchoring and adjustment, or availability bias stemming from asymmetry of information, was observed in the prediction of cumulative precipitation, and found to delay evacuation or evacuation orders.

kn-title=A Major Intestinal Catabolite of Quercetin Glycosides, 3-Hydroxyphenylacetic Acid, Protects the Hepatocytes from the Acetaldehyde-Induced Cytotoxicity through the Enhancement of the Total Aldehyde Dehydrogenase Activity
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Aldehyde dehydrogenases (ALDHs) are the major enzyme superfamily for the aldehyde metabolism. Since the ALDH polymorphism leads to the accumulation of acetaldehyde, we considered that the enhancement of the liver ALDH activity by certain food ingredients could help prevent alcohol-induced chronic diseases. Here, we evaluated the modulating effects of 3-hydroxyphenylacetic acid (OPAC), the major metabolite of quercetin glycosides, on the ALDH activity and acetaldehyde-induced cytotoxicity in the cultured cell models. OPAC significantly enhanced the total ALDH activity not only in mouse hepatoma Hepa1c1c7 cells, but also in human hepatoma HepG2 cells. OPAC significantly increased not only the nuclear level of aryl hydrocarbon receptor (AhR), but also the AhR-dependent reporter gene expression, though not the nuclear factor erythroid-2-related factor 2 (Nrf2)-dependent one. The pretreatment of OPAC at the concentration required for the ALDH upregulation completely inhibited the acetaldehyde-induced cytotoxicity. Silencing AhR impaired the resistant effect of OPAC against acetaldehyde. These results strongly suggested that OPAC protects the cells from the acetaldehyde-induced cytotoxicity, mainly through the AhR-dependent and Nrf2-independent enhancement of the total ALDH activity. Our findings suggest that OPAC has a protective potential in hepatocyte models and could offer a new preventive possibility of quercetin glycosides for targeting alcohol-induced chronic diseases.

kn-title=Irrationality of Attitudes toward Safety under Complexity and Uncertainty Leading to Asymmetry of Information
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigated how complexity and uncertainty, the probability of accidents, and the probability of financial trouble affected individuals' recognition of validity of irrational risk-seeking decisions. As a result of conducting a multiple regression analysis on the validation score for irrational risk-seeking alternative obtained by a questionnaire survey, we found that the validity score for an irrational risk-seeking alternative was higher when both complexity and uncertainty were high than when both complexity and uncertainty were low, which means that high complexity and high uncertainty in the situation of decision making more readily leads to an irrational risk-seeking behavior that might trigger a major accident. Beyond complexity and uncertainty, the damage of major accident alpha, the decrease of the probability of major accidents and the increase of the probability of financial trouble (economic factor) were also found to promote the choice of irrational risk-seeking alternatives. Some implications for safety management under high complexity and uncertainty are discussed.

kn-title=Citric Acid-Mediated Abiotic Stress Tolerance in Plants
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Several recent studies have shown that citric acid/citrate (CA) can confer abiotic stress tolerance to plants. Exogenous CA application leads to improved growth and yield in crop plants under various abiotic stress conditions. Improved physiological outcomes are associated with higher photosynthetic rates, reduced reactive oxygen species, and better osmoregulation. Application of CA also induces antioxidant defense systems, promotes increased chlorophyll content, and affects secondary metabolism to limit plant growth restrictions under stress. In particular, CA has a major impact on relieving heavy metal stress by promoting precipitation, chelation, and sequestration of metal ions. This review summarizes the mechanisms that mediate CA-regulated changes in plants, primarily CA's involvement in the control of physiological and molecular processes in plants under abiotic stress conditions. We also review genetic engineering strategies for CA-mediated abiotic stress tolerance. Finally, we propose a model to explain how CA's position in complex metabolic networks involving the biosynthesis of phytohormones, amino acids, signaling molecules, and other secondary metabolites could explain some of its abiotic stress-ameliorating properties. This review summarizes our current understanding of CA-mediated abiotic stress tolerance and highlights areas where additional research is needed.

kn-title=Asymmetry of Authority or Information Underlying Insufficient Communication Associated with a Risk of Crashes or Incidents in Passenger Railway Transportation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Similar crashes or incidents may recur as a result of insufficient communication in uncertain and risky situations that potentially threaten safety. The common root causes of insufficient communication across a series of incidents and crashes must be explored in detail to prevent a vicious circle of similar incidents or crashes from occurring. This study summarizes a series of incidents and crashes (derailment due to excessive train speed) at JR West at the West Japan Railway Company (JR West) that are considered to have arisen from insufficient communication. The incidents included (i) resuming train service without confirming the number of passengers on board and leaving passengers behind the station at Higashi-Hiroshima station, (ii) continuing train service in spite of an apparent risk of a crash detected at Okayama station, and (iii) leaving the crack of the train hood as it was at Kokura station. We discuss the causes of insufficient communication (particularly in relation to the sharing of information) among the three branches of staff-the station staff, the conductor and train driver, and the train operation management center-that led to the incidents or crashes. Two factors contributed to the insufficient communication in the series of incidents and crashes: (a) Asymmetry of authority, which hinders the discussion of issues openly and equally among the branches concerned. (b) An unacceptable level of knowledge or information for all branches concerned.

kn-title=Cross-Cultural Analysis of Top Page Design Among Brazilian, Chinese, Japanese and United States Web Sites
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of present study was to reveal the differences of web design including cultural preference among the four countries that have different cultures. Twenty local municipal sites were randomly chosen from United States, Japan, China, and Brazil. The characteristics of these web sites was investigated from viewpoint of the following seven categories: (1) text, (2) layout, (3) navigation, (4) multimedia, (5) links, (6) items location, (7) color. When the web site had each factor, the researcher gave a "1" for that factor. Chi-square goodness-of-fit test was performed to compare the percentage of "0" or "1" of each factor among the four countries. Additionally, the correspondence analysis was performed to grasp the characteristics of each country. The characteristics of the top page design of the four countries were grasped based on these analyses.

kn-title=Development of an Eye-Gaze Input System With High Speed and Accuracy through Target Prediction Based on Homing Eye Movements
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, a method to predict a target on the basis of the trajectory of eye movements and to increase the pointing speed while maintaining high predictive accuracy is proposed. First, a predictive method based on ballistic (fast) eye movements (Approach 1) was evaluated in terms of pointing speed and predictive accuracy. In Approach 1, the so-called Midas touch problem (pointing to an unintended target) occurred, particularly when a small number of samples was used to predict a target. Therefore, to overcome the poor predictive accuracy of Approach 1, we developed a new predictive method (Approach 2) using homing (slow) eye movements rather than ballistic (fast) eye movements. Approach 2 overcame the disadvantage (inaccurate prediction) of Approach 1 by shortening the pointing time while maintaining high predictive accuracy.

kn-title=Neuroplastinβ-mediated upregulation of solute carrier family 22 member 18 antisense (SLC22A18AS) plays a crucial role in the epithelial-mesenchymal transition, leading to lung cancer cells' enhanced motility
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Our recent study revealed an important role of the neuroplastin (NPTN)β downstream signal in lung cancer dissemination in the lung. The molecular mechanism of the signal pathway downstream of NPTNβ is a serial activation of the key molecules we identified: tumor necrosis factor (TNF) receptor-associated factor 2 (TRAF2) adaptor, nuclear factor (NF)IA/NFIB heterodimer transcription factor, and SAM pointed-domain containing ETS transcription factor (SPDEF). The question of how dissemination is controlled by SPDEF under the activated NPTNβ has not been answered. Here, we show that the NPTNβ-SPDEF-mediated induction of solute carrier family 22 member 18 antisense (SLC22A18AS) is definitely required for the epithelial-mesenchymal transition (EMT) through the NPTNβ pathway in lung cancer cells. In vitro, the induced EMT is linked to the acquisition of active cellular motility but not growth, and this is correlated with highly disseminative tumor progression in vivo. The publicly available data also show the poor survival of SLC22A18AS-overexpressing lung cancer patients. Taken together, these data highlight a crucial role of SLC22A18AS in lung cancer dissemination, which provides novel input of this molecule to the signal cascade of NPTNβ. Our findings contribute to a better understanding of NPTNβ-mediated lung cancer metastasis.

kn-title=Inhibition of light-induced stomatal opening by allyl isothiocyanate does not require guard cell cytosolic Ca2+ signaling
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The glucosinolate-myrosinase system is a well-known defense system that has been shown to induce stomatal closure in Brassicales. Isothiocyanates are highly reactive hydrolysates of glucosinolates, and an isothiocyanate, allyl isothiocyanate (AITC), induces stomatal closure accompanied by elevation of free cytosolic Ca2+ concentration ([Ca2+](cyt)) in Arabidopsis. It remains unknown whether AITC inhibits light-induced stomatal opening. This study investigated the role of Ca2+ in AITC-induced stomatal closure and inhibition of light-induced stomatal opening. AITC induced stomatal closure and inhibited light-induced stomatal opening in a dose-dependent manner. A Ca2+ channel inhibitor, La3+, a Ca(2+)chelator, EGTA, and an inhibitor of Ca2+ release from internal stores, nicotinamide, inhibited AITC-induced [Ca2+](cyt) elevation and stomatal closure, but did not affect inhibition of light-induced stomatal opening. AITC activated non-selective Ca2+-permeable cation channels and inhibited inward-rectifying K+ (K-in(+)) channels in a Ca2+-independent manner. AITC also inhibited stomatal opening induced by fusicoccin, a plasma membrane H+-ATPase activator, but had no significant effect on fusicoccin-induced phosphorylation of the penultimate threonine of H+-ATPase. Taken together, these results suggest that AITC induces Ca2+ influx and Ca2+ release to elevate [Ca2+](cyt), which is essential for AITC-induced stomatal closure but not for inhibition of K-in(+) channels and light-induced stomatal opening.

kn-title=Differential Response of Sugar Beet to Long-Term Mild to Severe Salinity in a Soil-Pot Culture
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Attempts to cultivate sugar beet (Beta vulgaris spp. vulgaris) in the sub-tropical saline soils are ongoing because of its excellent tolerance to salinity. However, the intrinsic adaptive physiology has not been discovered yet in the sub-tropical climatic conditions. In this study, we investigated morpho-physiological attributes, biochemical responses, and yield of sugar beet under a gradient of salinity in the soil-pot culture system to evaluate its adaptive mechanisms. Results exhibited that low and high salinity displayed a differential impact on growth, photosynthesis, and yield. Low to moderate salt stress (75 and 100 mM NaCl) showed no inhibition on growth and photosynthetic attributes. Accordingly, low salinity displayed simulative effect on chlorophyll and antioxidant enzymes activity which contributed to maintaining a balanced H2O2 accumulation and lipid peroxidation. Furthermore, relative water and proline content showed no alteration in low salinity. These factors contributed to improving the yield (tuber weight). On the contrary, 250 mM salinity showed a mostly inhibitory role on growth, photosynthesis, and yield. Collectively, our findings provide insights into the mild-moderate salt adaptation strategy in the soil culture test attributed to increased water content, elevation of photosynthetic pigment, better photosynthesis, and better management of oxidative stress. Therefore, cultivation of sugar beet in moderately saline-affected soils will ensure efficient utilization of lands.

kn-title=Yeast screening system reveals the inhibitory mechanism of cancer cell proliferation by benzyl isothiocyanate through down-regulation of Mis12
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Benzyl isothiocyanate (BITC) is a naturally-occurring isothiocyanate derived from cruciferous vegetables. BITC has been reported to inhibit the proliferation of various cancer cells, which is believed to be important for the inhibition of tumorigenesis. However, the detailed mechanisms of action remain unclear. In this study, we employed a budding yeast Saccharomyces cerevisiae as a model organism for screening. Twelve genes including MTW1 were identified as the overexpression suppressors for the antiproliferative effect of BITC using the genome-wide multi-copy plasmid collection for S. cerevisiae. Overexpression of the kinetochore protein Mtw1 counteracts the antiproliferative effect of BITC in yeast. The inhibitory effect of BITC on the proliferation of human colon cancer HCT-116 cells was consistently suppressed by the overexpression of Mis12, a human orthologue of Mtw1, and enhanced by the knockdown of Mis12. We also found that BITC increased the phosphorylated and ubiquitinated Mis12 level with consequent reduction of Mis12, suggesting that BITC degrades Mis12 through an ubiquitin-proteasome system. Furthermore, cell cycle analysis showed that the change in the Mis12 level affected the cell cycle distribution and the sensitivity to the BITC-induced apoptosis. These results provide evidence that BITC suppresses cell proliferation through the post-transcriptional regulation of the kinetochore protein Mis12.

kn-abstract= Plants closing stomata in the presence of harmful gases is believed to be a stress avoidance mechanism. SO2 , one of the major airborne pollutants, has long been reported to induce stomatal closure, yet the mechanism remains unknown. Little is known about the stomatal response to airborne pollutants besides O3 . SLOW ANION CHANNEL-ASSOCIATED 1 (SLAC1) and OPEN STOMATA 1 (OST1) were identified as genes mediating O3 -induced closure. SLAC1 and OST1 are also known to mediate stomatal closure in response to CO2 , together with RESPIRATORY BURST OXIDASE HOMOLOGs (RBOHs). The overlaying roles of these genes in response to O3 and CO2 suggested that plants share their molecular regulators for airborne stimuli. Here, we investigated and compared stomatal closure event induced by a wide concentration range of SO2 in Arabidopsis through molecular genetic approaches. O3 - and CO2 -insensitive stomata mutants did not show significant differences from the wild type in stomatal sensitivity, guard cell viability, and chlorophyll content revealing that SO2 -induced closure is not regulated by the same molecular mechanisms as for O3 and CO2 . Nonapoptotic cell death is shown as the reason for SO2 -induced closure, which proposed the closure as a physicochemical process resulted from SO2 distress, instead of a biological protection mechanism.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Mouse melanoma B16-BL6 cells are useful cells for cancer metastatic studies. To understand the metastatic principle at molecular levels, it is necessary to carry out experiments in which cancer cells and their normal counterparts are compared. However, unlike normal human melanocytes, preparation of normal mouse melanocytes is quite difficult due to the lack of marketing and insufficient information on an established protocol for primary culture of mouse melanocytes. In this study, we aimed to establish a convenient method for primary culture of mouse melanocytes on the basis of the protocol for human melanocytes. The main obstacles to preparing pure mouse melanocytes are how to digest mouse skin tissue and how to reduce the contamination of keratinocytes and fibroblasts. The obstacles were overcome by collagenase digestion for skin specimens, short time trypsinization for separating melanocytes and keratinocytes, and use of 12-O-Tetradecanoylphorbol 13-acetate (TPA) and cholera toxin in the culture medium. These supplements act to prevent the proliferation of keratinocytes and fibroblasts, respectively. The convenient procedure enabled us to prepare a pure culture of normal mouse melanocytes. Using enriched normal mouse melanocytes and cancerous B16-BL6 cells, we compared the expression levels of melanoma cell adhesion molecule (MCAM), an important membrane protein for melanoma metastasis, in the cells. The results showed markedly higher expression of MCAM in B16-BL6 cells than in normal mouse melanocytes.

kn-title=Critical role of the MCAM-ETV4 axis triggered by extracellular S100A8/A9 in breast cancer aggressiveness

kn-abstract=Metastatic breast cancer is the leading cause of cancer-associated death in women. The progression of this fatal disease is associated with inflammatory responses that promote cancer cell growth and dissemination, eventually leading to a reduction of overall survival. However, the mechanism(s) of the inflammation-boosted cancer progression remains unclear. In this study, we found for the first time that an extracellular cytokine, S100A8/A9, accelerates breast cancer growth and metastasis upon binding to a cell surface receptor, melanoma cell adhesion molecule (MCAM). Our molecular analyses revealed an important role of ETS translocation variant 4 (ETV4), which is significantly activated in the region downstream of MCAM upon S100A8/A9 stimulation, in breast cancer progression in vitro as well as in vivo. The MCAM-mediated activation of ETV4 induced a mobile phenotype called epithelial-mesenchymal transition (EMT) in cells, since we found that ETV4 transcriptionally upregulates ZEB1, a strong EMT inducer, at a very high level. In contrast, downregulation of either MCAM or ETV4 repressed EMT, resulting in greatly weakened tumor growth and lung metastasis. Overall, our results revealed that ETV4 is a novel transcription factor regulated by the S100A8/A9-MCAM axis, which leads to EMT through ZEB1 and thereby to metastasis in breast cancer cells. Thus, therapeutic strategies based on our findings might improve patient outcomes.

kn-title=Involvement of OST1 Protein Kinase and PYR/PYL/RCAR Receptors in Methyl Jasmonate-Induced Stomatal Closure in Arabidopsis Guard Cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Methyl jasmonate (MeJA) induces stomatal closure. It has been shown that stomata of many ABA-insensitive mutants are also insensitive to MeJA, and a low amount of ABA is a prerequisite for the MeJA response. However, the molecular mechanisms of the interaction between ABA and MeJA signaling remain to be elucidated. Here we studied the interplay of signaling of the two hormones in guard cells using the quadruple ABA receptor mutant pyr1 pyl1 pyl2 pyl4 and ABA-activated protein kinase mutants ost1-2 and srk2e. In the quadruple mutant, MeJA-induced stomatal closure, H2O2 production, nitric oxide (NO) production, cytosolic alkalization and plasma membrane Ca(2+)-permeable current (ICa) activation were not impaired. At the same time, the inactivation of the inward-rectifying K(+) current was impaired. In contrast to the quadruple mutant, MeJA-induced stomatal closure, H2O2 production, NO production and cytosolic alkalization were impaired in ost1-2 and srk2e as well as in aba2-2, the ABA-deficient mutant. The activation of ICa was also impaired in srk2e. Collectively, these results indicated that OST1 was essential for MeJA-induced stomatal closure, while PYR1, PYL1, PYL2 and PYL4 ABA receptors were not sufficient factors. MeJA did not appear to activate OST1 kinase activity. This implies that OST1 mediates MeJA signaling through an undetectable level of activity or a non-enzymatic action. MeJA induced the expression of an ABA synthesis gene, NCED3, and increased ABA contents only modestly. Taken together with previous reports, this study suggests that MeJA signaling in guard cells is primed by ABA and is not brought about through the pathway mediated by PYR1, PYL1 PYL2 and PYL4.

kn-title=DNAX-activating protein 10 (DAP10) membrane adaptor associates with receptor for advanced glycation end products (RAGE) and modulates the RAGE-triggered signaling pathway in human keratinocytes.
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= The receptor for advanced glycation end products (RAGE) is involved in the pathogenesis of many inflammatory, degenerative, and hyperproliferative diseases, including cancer. Previously, we revealed mechanisms of downstream signaling from ligand-activated RAGE, which recruits TIRAP/MyD88. Here, we showed that DNAX-activating protein 10 (DAP10), a transmembrane adaptor protein, also binds to RAGE. By artificial oligomerization of RAGE alone or RAGE-DAP10, we found that RAGE-DAP10 heterodimer formation resulted in a marked enhancement of Akt activation, whereas homomultimeric interaction of RAGE led to activation of caspase 8. Normal human epidermal keratinocytes exposed to S100A8/A9, a ligand for RAGE, at a nanomolar concentration mimicked the pro-survival response of RAGE-DAP10 interaction, although at a micromolar concentration, the cells mimicked the pro-apoptotic response of RAGE-RAGE. In transformed epithelial cell lines, A431 and HaCaT, in which endogenous DAP10 was overexpressed, and S100A8/A9, even at a micromolar concentration, led to cell growth and survival due to RAGE-DAP10 interaction. Functional blocking of DAP10 in the cell lines abrogated the Akt phosphorylation from S100A8/A9-activated RAGE, eventually leading to an increase in apoptosis. Finally, S100A8/A9, RAGE, and DAP10 were overexpressed in the psoriatic epidermis. Our findings indicate that the functional interaction between RAGE and DAP10 coordinately regulates S100A8/A9-mediated survival and/or apoptotic response of keratinocytes.

kn-abstract= We employ the methodology of “Compulsory Repetitive Learning” to improve student learning and performance in fundamental subjects. It is a challenge for many universities to intrinsically motivate students and it is a demanding issue that a large part of students do not sufficiently do homework. Here, we let students solve the problems associated with the teaching immediately following each lecture. Through the usage of “Compulsory Repetitive Learning”, each student as well as the subject teacher(s) could monitor and evaluate the quality of student learning and performance.

kn-abstract=A 67-year-old man was admitted to our hospital presenting with a liver injury. He had used several types of oral medication for the prior 2 years, including rosuvastatin calcium for hypertension, hyperlipidemia, and prostatic hypertrophy. His liver dysfunction was noted for the first time in February 2013, and at re-examination in March 2013 he showed exacerbation of the liver dysfunction, he was admitted to our hospital at that time. We stopped all of his oral medications, and his liver function improved steadily. We conducted a drug-induced lymphocyte transformation test (DLST), and the rosuvastatin calcium result was positive. He was diagnosed as having a drug-induced (by rosvastatin calcium) liver injury. He resumed oral medications other than rosuvastatin calcium from the time of discharge, with no exacerbation of liver dysfunction since then. Reports of drug-induced liver injury due to drugs with a long-term oral administration are extremely rare. We discuss the relevant literature herein.

kn-title=Nuclear factor-kappaB sensitizes to benzyl isothiocyanate-induced antiproliferation in p53-deficient colorectal cancer cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Benzyl isothiocyanate (BITC), a dietary isothiocyanate derived from cruciferous vegetables, inhibits the proliferation of colorectal cancer cells, most of which overexpress β-catenin as a result of mutations in the genes for adenomatous polyposis coli or mutations in β-catenin itself. Because nuclear factor-κB (NF-κB) is a plausible target of BITC signaling in inflammatory cell models, we hypothesized that it is also involved in BITC-inhibited proliferation of colorectal cancer cells. siRNA-mediated knockdown of the NF-κB p65 subunit significantly decreased the BITC sensitivity of human colorectal cancer HT-29 cells with mutated p53 tumor suppressor protein. Treating HT-29 cells with BITC induced the phosphorylation of IκB kinase, IκB-α and p65, the degradation of IκB-α, the translocation of p65 to the nucleus and the upregulation of NF-κB transcriptional activity. BITC also decreased β-catenin binding to a positive cis element of the cyclin D1 promoter and thus inhibited β-catenin-dependent cyclin D1 transcription, possibly through a direct interaction between p65 and β-catenin. siRNA-mediated knockdown of p65 confirmed that p65 negatively affects cyclin D1 expression. On the other hand, when human colorectal cancer HCT-116 cells with wild-type p53 were treated with BITC, translocation of p65 to the nucleus was inhibited rather than enhanced. p53 knockout increased the BITC sensitivity of HCT-116 cells in a p65-dependent manner, suggesting that p53 negatively regulates p65-dependent effects. Together, these results identify BITC as a novel type of antiproliferative agent that regulates the NF-κB pathway in p53-deficient colorectal cancer cells.

kn-abstract=The definite diagnosis of persimmon phytobezoar (i.e., diospyrobezoar) is often accomplished by a component analysis using infrared spectroscopy. However, no studies have been conducted to investigate which substance is the best as a standard for the component analysis. Here we analyzed tannic acid, Japanese persimmon (kaki), fermented persimmon extract (kaki-shibu), conventional dried persimmon, and dried persimmon smoked in sulfur (ampo-kaki) by infrared spectroscopy to determine which would be optimal as a component analysis standard. The spectrum between 1,600 to 600cm-1 of a persimmon phytobezoar was quite similar to the spectrum of kaki-shibu rather than that of tannic acid. Consequently, we conclude that kaki-shibu should be used as a standard for infrared spectroscopy analyses of persimmon phytobezoars.

kn-title=Inhibition of RAGE signaling through the intracellular delivery of inhibitor peptides by PEI cationization
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The receptor for advanced glycation end products (RAGE) is a multi-ligand cell surface receptor and a member of the immunoglobulin superfamily. RAGE is involved in a wide range of inflammatory, degenerative and hyper-proliferative disorders which span over different organs by engaging diverse ligands, including advanced glycation end products, S100 family proteins, high-mobility group protein B1 (HMGB1) and amyloid beta. We previously demonstrated that the cytoplasmic domain of RAGE is phosphorylated upon the binding of ligands, enabling the recruitment of two distinct pairs of adaptor proteins, Toll-interleukin 1 receptor domain-containing adaptor protein (TIRAP) and myeloid differentiation protein 88 (MyD88). This engagement allows the activation of downstream effector molecules, and thereby mediates a wide variety of cellular processes, such as inflammatory responses, apoptotic cell death, migration and cell growth. Therefore, inhibition of the binding of TIRAP to RAGE may abrogate intracellular signaling from ligand-activated RAGE. In the present study, we developed inhibitor peptides for RAGE signaling (RAGE-I) by mimicking the phosphorylatable cytosolic domain of RAGE. RAGE-I was efficiently delivered into the cells by polyethylenimine (PEI) cationization. We demonstrated that RAGE-I specifically bound to TIRAP and abrogated the activation of Cdc42 induced by ligand-activated RAGE. Furthermore, we were able to reduce neuronal cell death induced by an excess amount of S100B and to inhibit the migration and invasion of glioma cells in vitro. Our results indicate that RAGE-I provides a powerful tool for therapeutics to block RAGE-mediated multiple signaling.

kn-abstract= An 84-year-old man, who had been found to have a submucosal tumor in the ascending colon two years before, was admitted to our hospital for right lower quadrant abdominal pain and melena. An abdominal computed tomography (CT) scan showed intussusception in the ascending colon, resulting from a fat-density tumor. The intussusception was located by colonoscopy. Since the colonic tumor was enlarged in comparison with two years ago and had an ulcer at the top of the tumor, there was the possibility of malignancy and recurrence of intussusception. He underwent a laparoscopy-assisted right colectomy with lymph node dissection. Pathologically, the tumor of the ascending colon was a benign lipoma.

kn-title=Down-regulation of BiP/GRP78 sensitizes resistant prostate cancer cells to gene-therapeutic overexpression of REIC/Dkk-3
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We have recently shown that an adenovirus carrying REIC/Dkk-3 (Ad-REIC) exhibits a potent tumor-specific cell-killing function for various human cancers. It has also become evident that some human cancers are resistant to Ad-REIC-induced apoptosis. The aim of the present study was to determine the molecular mechanisms of resistance to Ad-REIC. First, we isolated resistant clones from a human prostate cancer cell line, PC3, after repeated exposure to Ad-REIC. Infection efficiency of the adenovirus vector and expression level of REIC/Dkk-3 in the resistant clones were similar to those in the parental PC3 cells. By screening for alteration in levels and functional status of proteins involved in Ad-REIC-induced apoptosis, we found that BiP/GRP78, an ER-residing chaperone protein, was expressed at higher levels consistently among resistant cells. Expression levels of BiP and rates of apoptosis induced by Ad-REIC were inversely correlated. Down-regulation of BiP with siRNA sensitized the resistant cells to Ad-REIC in vivo as well as in culture. These results indicate that BiP is a major determinant of resistance to Ad-REIC-induced apoptosis. Thus BiP is useful for diagnosis of inherent and acquired resistance of cancers and also as a target molecule to overcome resistance to the gene therapeutic Ad-REIC.

kn-title=Overexpression of REIC/Dkk-3 in Normal Fibroblasts Suppresses Tumor Growth via Induction of Interleukin-7
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We previously showed that the tumor suppressor gene REIC/Dkk-3, when overexpressed by an adenovirus (Ad-REIC), exhibited a dramatic therapeutic effect on human cancers through a mechanism triggered by endoplasmic reticulum stress. Adenovirus vectors show no target cell specificity and thus may elicit unfavorable side effects through infection of normal cells even upon intra-tumoral injection. In this study, we examined possible effects of Ad-REIC on normal cells. We found that infection of normal human fibroblasts (NHF) did not cause apoptosis but induced production of interleukin (IL)-7. The induction was triggered by endoplasmic reticulum stress and mediated through IRE1 alpha, ASK1, p38, and IRF-1. When Ad-REIC-infected NHF were transplanted in a mixture with untreated human prostate cancer cells, the growth of the cancer cells was significantly suppressed. Injection of an IL-7 antibody partially abrogated the suppressive effect of Ad-REIC-infected NHF. These results indicate that Ad-REIC has another arm against human cancer, an indirect host-mediated effect because of overproduction of IL-7 by mis-targeted NHF, in addition to its direct effect on cancer cells.

kn-abstract=We experienced a case of esophageal carcinosarcoma with a component of small cell carcinoma. The patient was a 73-year-old man. We administered chemotherapy of CDDP+VP-16, and performed an operation after 2 courses of this chemotherapy. Subtotal esophagectomy and reconstruction with the small intestine was performed. More than three years after resection, he remains alive and recurrence-free. There are few cases of esophageal carcinosarcoma and small cell carcinoma. We report this rare case herein.

kn-abstract=We experienced a case of gastric aberrant pancreas with acute pancreatitis. The patient was a 42-year-old man. He was referred to our hospital because of epigastric pain. A CT scan and endoscopic examination revealed a gastric submucosal tumor with inflammation. His serum amylase level was high at 222 IU/l. Endoscopic ultrasonography revealed a hypoechoic mass lesion, 3 cm in diameter, at the body of his stomach. Endoscopic ultrasoundscopy-guided fine needle aspiration was performed. Pathological examination showed pancreatic tissue. So, he underwent partial gastrectomy due to gastric aberrant pancreas with pancreatitis. There are very few cases of gastric aberrant pancreas with pancreatitis on record.

kn-title=村田氏黴毒血清反應ニ就テ

kn-subtitle=
en-abstract=
kn-abstract=Murata hat seine einfache Methode für die Serodiagnose der Syphilis schon mehrmals mitgeteilt (Japan. Zeitschr. f. Dermat. u. Syphilis. Bd. 22 H. 11, Bd. 23 H. 6, Zentralbl. f. Haut- u. Geschlechtskrankh. Bd. 9, S. 133 usw.). Ich habe diese Methode in 743 Fällen geprüft u. die Uebereinstimmung in 694 (93, 4%) mit WR. gefunden. Die Muratasche Methode fällt beim seronegativen primären Stadium und in der negativen Zeit von WR. nach der antisyphilitischen Behandlung oft positiv aus; also scheint sie empfindlicher als WR. zu sein. Sie reagiert besser im inaktiven Serum als im aktiven. Doch ist sie sowohl im hämolytischen als auch im getrübten Serum vom schwach positiven Blut schwer ablesbar, wenn sie auch dabei im stark positiven Serum leicht verständlich ist. Ich bin überzeugt davon, dass sie einfache u. gute Methode ist und der WR. gute Beihilfe leisten kann.

Muratasche Reaktion und M. T. R. sind zwar empfindlich als Seroreaktion, jedoch gilt dies der Liquorreaktion wenig. Die Untersteinsche Modifikation der M. T. R. ist ebensowenig empfindlich bei uns.

en-abstract=
kn-abstract=1) The seronegative rabbitsserum in the Browning, Murata and M.K.R. II. tests is not influenced by the injection of Bagnon-Stark and this result remains unaltered even after three consecutive injection. 2) The effect of this medicament upon the nop-specificity in the Murata and the M.K.R. II. tests is observed after the first injection. The non-specificity in the Murata test disappears or shows negative tendency in 30 seconds after the injection, and the similar result is recognised in 1 hour after the injection in the M.K.R. II. test. 3) The duration of time before the disappearance of non-specificity in the two tests varies according the strength of the reaction. The weak positiveness before the experiment disappears in 3 hours after the injection in either of the two tests. But in the case of strong positiveness 10 hours is required to shows the negative tendency after the injection, and in either of the two cases the complete disappearance of non-specificity is observed in 24 hours after the infection. 4) The effect of Bagnon-Stark on the rabbit syphilis that has shown strong positiveness in the Browning, Murata and M.K.R. II. tests is wholly null and void. 5) The disappearance of non-specificity in the Murata and the M.K.R. II. tests by the injection of Bagnon-Stark is probably due to the alteration of organic metabolism as well as to the fall of temperature in the rabbit.

kn-abstract=I have injected penicillin in rabbits in which spirochaeta pallida was oculated at the period when the precipitation (Murata and Kahn) turned positive and observed the transition of the serum reaction, alteration of the local state and disappearance of spirochaeta from the local area and obtained the following results: 1) In the cases in which 50,000 U. of penicillin were injected, the influence of penicillin on the 3 reactions (WaR, Murata and Kahn) was rather unstable and the term needed for the 3 reactions to turn negative was prolonged, i.e., WaR turned negative in 66.5 days after the oculation (54.5 days after the injection), Murata's reaction in 94.5 days (82.5 days after the injection), and Kahn's reaction in 91.0 days (79.0 days after the injection). 2) In the 100,000 U. injected cases, WaR turned negative in 63.0 days after the oculation (50.7 days after the injection), Murata's reaction in 84.0 days (71.7 days after injection), Kahn's reaction in 92.8 days (80.5 days after injection). 3) In the cases in which 200,000 U. were injected, a definite effect of penicillin on the serum reaction was observed when compared with the previous 2 groups, i.e., WaR turned negative in 11.6 days after oculation (7.0 days after injection), Murata's reaction in 28.0 days (18.6 days after injection), and Kahn's reaction in 46.6 days (37.3 days after injection). 4) In the observation of the effect of penicillin on the local state: in 50,000 U. injected cased, stuntedness of the local state and the prolongation of the incubation could be observed and the local state cured in 36.0 days, in 100,000 U. injected cases, the prolongation of incubation could be observed but the local state occured and took 25.7 days to disappear and in 200,000 U. injected cases, the local state was completely prevented and the syphilitic local symptoms did not appear. 5) 200,000 U. of penicillin showed a definite effect on the existence of spirochaeta, i.e., the spirochaeta conld not be detected at all, and in 50,000 U. injected cases, the effect of injection was not distinct and they disappeared in 16.0 days in the former cases and in 9.2 days in the latter cases. 6) The recurrens of the serum reaction and the local state could not be observed during the observation of 4 months on the average. Comparing the above results with those described in Part II, where the injections were given at the period when WaR turned positive, the following results were obtained: 7) Concerning the 50,000 U. and 100,000 U. injected cases, the term needed for the serum reaction to turn negative was prolonged in the cases in which the injections were given at the period when precipitation turned positive, when compared with the cases in which injections were given at the period when WaR turned positive, therforee the time required for the absorption of local state and the disappearance of spirochaeta was also prolonged. 8) In the observation of 200,000 U. injected cases: WaR turned negative in 42.6 days after oculation (21.3 days after inlection), Murata in 56 days (34.6 days after injection), Kahn in 60.6 days (39.3 days after injection) in the cases in which injections were given at the period when WaR turned positive, and in the cases where injections were made at the period when precipitation turned positive, WaR turned negative in 11.6 days after oculation (7 days after injection), Murata in 28.0 days (18.6 days after injection), Kahn in 46.6 days (37.3 days after injection), i.e., distinct reduction could be observed in the latter cases. 9) In 200,000 U. injected cases, a remarkable and regular effect of penicillin could be observed when compared with other 2 groups, and especialy in the cases in which injections were given at the period when the precipitation turned positive the effect was more distinct. 10) In 50,000 U. and 100,000 U. injected cases no distinct and regular effect of penicillin could be observed.

kn-abstract=
The 180 bp family of tandem repetitive sequences, which constitutes the major centromeric satellite in Arabidopsis thaliana, is thought to play important roles in kinetochore assembly. To assess the centromere activities of the 180 bp repeats, we performed indirect fluorescence immunolabeling with antibodies against phosphorylated histone H3 at Serl0, HTR12 (Arabidopsis centromeric histone H3 variant) and AtCENP-C (Arabidopsis CENP-C homologue) for the A. thaliana cell cultures. The immunosignals from all three antibodies appeared on all sites of the 180 bp,repeats detected by fluorescence in situ hybridization. However, some of the 180 bp repeat clusters, particularly those that were long or stretched at interphase, were not fully covered with the signals from anti-HTR12 or AtCENP-C. Chromatin fiber immunolabeling clearly revealed that the centromeric proteins examined in this study, localize only at the knobs on the extended chromatin fibers, which form a limited part of the 180 bp clusters. Furthermore, outer HTR12 and inner phosphohistone H3 (Ser1O) localization at the kinetochores of metaphase chromosomes suggests that two kinds of histone H3 (a centromere variant and a phosphorylated form) might be linked to different roles in centromere functionality; the former for spindle-fiber attachment, and the latter for chromatid cohesion.

The exposure of rats to 95 dB and 110 dB of noise acutely reduced their hepatic glycogens. Vitamin C (ascorbic acid) and vitamin E (alpha -tocopherol) attenuated the noise-inducedacute reduction in the hepatic glycogen contents. This result suggests that antioxidants could reduce the change via reactive oxygen species. Vitamin B12 (cobalamin) delayed the noiseinduced change, a finding that suggests that vitamin B12 could postpone the acute change via compensating for vitamin B12 deficiency. en-copyright= kn-copyright= en-aut-name=ZhuBei-Wei en-aut-sei=Zhu en-aut-mei=Bei-Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PiaoMei-Lan en-aut-sei=Piao en-aut-mei=Mei-Lan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhangYu en-aut-sei=Zhang en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanSong en-aut-sei=Han en-aut-mei=Song kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AnQing-Da en-aut-sei=An en-aut-mei=Qing-Da kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TadaMikiro en-aut-sei=Tada en-aut-mei=Mikiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Dalian Institute of Light Industry affil-num=2 en-affil= kn-affil=Okayama Univeristy affil-num=3 en-affil= kn-affil=Dalian Institute of Light Industry affil-num=4 en-affil= kn-affil=Okayama University affil-num=5 en-affil= kn-affil=Dalian Institute of Light Industry affil-num=6 en-affil= kn-affil=Okayama University affil-num=7 en-affil= kn-affil=Okayama University en-keyword=α-tocopherol kn-keyword=α-tocopherol en-keyword=ascorbic acid kn-keyword=ascorbic acid en-keyword=cobalamin kn-keyword=cobalamin en-keyword=hepatic glycogen kn-keyword=hepatic glycogen en-keyword=noise kn-keyword=noise 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=2010 dt-pub=20100325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stage-specific embryonic antigen-4を用いた歯の幹細胞の同定 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MurataSatoko en-aut-sei=Murata en-aut-mei=Satoko kn-aut-name=村田智子 kn-aut-sei=村田 kn-aut-mei=智子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=342 end-page=347 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Image and Layered Structure on Web Search Performance -Evaluation on the Basis of Movement Distance of Mouse Pointer- en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this paper was to explore the effects of image addition and layered structure on Web search performance on the basis of the search time and the movement trajectory of mouse pointer. The difference of search characteristics between young and older adults was also examined. Older adults tended to take more time to search for the linked item especially when the layered structure was deep. For the deep layered structure, both young and older adults allocate more time to think which items should be selected than to operate a mouse. For all participants, less mouse movement was observed for the image-based link condition than for the character-based link condition. This tendency was more remarkable for older adults. Moreover, it was clarified that more mouse movement was observed with the increase of the number of hyperlinks per Web page. When the layered structure was shallow, the following difference of mouse operation characteristics between young and older adults was observed: Older adults made an attempt to locate the search item while moving a mouse simultaneously. On the other hand, young adults began to move a mouse after locating the search item. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= en-aut-name=HayamiTakehito en-aut-sei=Hayami en-aut-mei=Takehito kn-aut-name=早見武人 kn-aut-sei=早見 kn-aut-mei=武人 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TakahashiRina kn-aut-sei=Takahashi kn-aut-mei=Rina aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University affil-num=4 en-affil= kn-affil=Japan Digital Laboratory Co.

The following two situations were used to address the issue above: (1) operation of a "Back" button, and (2) operation of a hyperlink. When the operation of "Back" button was necessary, the task completion time of older adults was 2.3 times as long as that of young adults. Such a difference must be obtained, because older adults need more time to recognize and understand the layered structure. When operation "Back" button in a raw, the task completion time of older adults was 3.9 times as long as that of young adults. Moreover, the task completion time of older adults increased in case of searching in the deep layered Web site due to the slower and declined cognition and judgment. When selecting a hyperlink, the task completion time of older adults was 12.1 times as long as that of young adults. On the basis of this tendency, we inferred that older adults took more time and became more careful when selecting a hyperlink. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TakahashiRina kn-aut-sei=Takahashi kn-aut-mei=Rina aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Japan Digital Laboratory Co.

The rotation torque of an encoder and the rotation diameter were selected as experimental parameters. An attempt was made to identify the optimal and recommended condition of rotation torque and diameter. It was demonstrated that the thumb-operated dial-type integrated switch lead to faster task completion time as compared with the traditional integrated switch. As for the thumb-operated dial-type integrated switch, the following combination of the rotation torque and the rotation diameter were not proper: diameter of 20mm for the rotation torque of 12.9mN・m and 9.2mN・m, and diameters of 20mm and 40mm for the rotation torque of 8.6 mN・m. It was also suggested that the optimal condition cannot be identified using the condition of the rotation force only, and that the optimal condition must be determined taking into account the combination of the rotation torque and the rotation diameter. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=WangShuguang kn-aut-sei=Wang kn-aut-mei=Shuguang aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=320 end-page=325 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fundamental study for constructing a system to assist the left visual field of older drivers - Effectiveness of the alternative of the left front side-view mirror by the central visual field - en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to establish the basics of the systems that assist visibility of the left visual field for older drivers.

Participants performed multiple tasks where tracking task using a steering wheel was a primary task, and judgment of situations using a left or front display was a secondary task. How the display location affected the judgment performance was explored for both young and older adults. We counted the number of the warning during the tracking task and measured the percentage correct reaction to displayed stimulus and reaction sensitivity. We investigated how these measures ware affected by age and display location. Mean warning number during the tracking tasks, the percentage correct recognition of situations and d' was affected age and display location. The central display was found to increase the percentage correct recognitions of situations. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=UchidaYohei en-aut-sei=Uchida en-aut-mei=Yohei kn-aut-name=内田洋平 kn-aut-sei=内田 kn-aut-mei=洋平 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=316 end-page=319 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Skill of Eye-Hand Coordination in Calligraphy - Difference of Skill of Hand-Eye Coordination between Expert and Novice - en-subtitle= kn-subtitle= en-abstract= kn-abstract=A system that can simultaneously measure the movement of a brush tip and the eye-gaze position during a calligraphy task has been developed.

In this study, the following proposition was hypothesized: Social intelligence (SI), ability to evaluate appropriately the reliability of others, ability to carry out communication smoothly in organization, and emotional aspects (behavior on the basis of emotion or reasonability) are important factors and keys to prevent violation-based organizational error. A questionnaire which included items related to social intelligence (SI: social awareness and social facility), emotional intelligence (EI), ability to evaluate the reliability of others, ability to communicate smoothly in organization, behavioral characteristics (emotional- or reasonability-based behavior), and ability to make decisions and judge situations. An attempt was made to verify the hypothesis above by a survey using the questionnaire. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=YamamotoKohei en-aut-sei=Yamamoto en-aut-mei=Kohei kn-aut-name=山本康平 kn-aut-sei=山本 kn-aut-mei=康平 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=306 end-page=311 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of the menu selection method for eye-gaze input system - Comparison between young and older adults - en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the opportunity of older adults to use personal computer is increased more and more, the operation of a personal computer with a mouse is very annoying for older adults who cannot move his or her arm smoothly and effectively due to declined motor function. An attempt to move a cursor by an eye-gaze input system has been carried out as one solution to this problem. Until now, a menu selection method suitable for an eye-gaze input system has not been clarified. In this study, an effective menu selection for the eye-gaze input system was identified as a basic design parameter to develop a Web browser using an eye-gaze input system. Concretely, a menu selection method, that is, improved quick glance menu selection (I-QGMS) was proposed. The effectiveness was evaluated by means of the pointing accuracy, the pointing time, and the psychological rating on usability. On the basis of the evaluation experiment, the proposed I-QGMS was found to be effective especially for older adults. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=302 end-page=305 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Basic Study for Development of Web Browser suitable for Eye-gaze Input System - Identification of Optimal Click Method - en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, alternative methods of mouse click operation were discussed. The eye-gaze input system was used. The effectiveness was compared among three alternative methods of mouse click operation. The alternative methods in the eye-gaze input system included the eye fixation, the press of space button, and the wink (blink). The percentage correct recognition, the pointing time, the subjective evaluation of usability was used as evaluation measures. The arrangement of targets (vertical or horizontal) and the age were also considered as experimental factors, and it was explored how these factors affected the pointing performance. The percentage correct recognition of the horizontal direction was higher than that of the vertical direction. The pointing time became longer as follows: eye-gaze input system with eye fixation, mouse, eye-gaze input system with press of space button, and eye-gaze input system with wink. The age factor was found not to affect the pointing time so remarkably. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=326 end-page=329 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Educational plans in nursing departments The current state of nurse development en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the recent diversification of career paths in nursing, the establishment of a career development plan (CDP) system for nurses is becoming more important for improving the quality of nursing. The present study, conducted on chief nurses in general hospitals in Japan, aimed to ascertain how nursing education fosters the individual career development of nurses. As a result, We understood the next matter. 1) Training for mid-level nurses is provided by most hospitals, primarily in the form of in-hospital training. 2) More than 90% of the hospitals surveyed provided individual counseling for career development, either as needed or periodically. 3) The proportion of hospitals with fewer than 200 nurses that prepared individual educational plans was 7%; the proportion of hospitals with more than 210 nurses that prepared individual educational plans was 24% on average.4) By taking into account "nurse development", job rotation is viewed as part of nursing education. Next, we proposed the new method for evaluation of CDP to individual nurses using N-S table. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=OzawaYukio kn-aut-sei=Ozawa kn-aut-mei=Yukio aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KitaokaMasatoshi kn-aut-sei=Kitaoka kn-aut-mei=Masatoshi aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Kanagawa University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Kanagawa University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=258 end-page=263 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design method of Cockpit module in consideration of switch type, location of switch and display information for older drivers en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, the effects of switch type, location of switch, and display information on the primary driving task and the secondary switch operation were investigated. The switch type included an integrated and a non-integrated switch. These switches were located on the front left, on the left side, or around a steering wheel. We prepared three displays with different display information (2.0, 4.1, and 5.9 bit). The tracking error, the mean operation time, the percentage of correct answer, NASA-TLX mental workload, and the subjective evaluation of usability were measured in order to analyze how these measures were affected by experimental factors above. The results suggested that young adults are better than older adults at both abilities on processing displayed information and operating switches. The integrated switch was found to affect driving performance than the non-integrated switch, and had little influence on switch operation. In addition, it was clarified that the switch located around a steering wheel had little influence on driving performance. Low display information was also found not to affect the performance. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=YamadaKeita en-aut-sei=Yamada en-aut-mei=Keita kn-aut-name=山田啓太 kn-aut-sei=山田 kn-aut-mei=啓太 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=254 end-page=257 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Visual information processing characteristics of drivers in prediction of dangerous situation - Comparison among novice, expert and non-licensed person - en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to examine the difference of visual information processing in KYT (Kiken Yochi Training) among novice, expert and non-licensed persons. In KYT tasks, participants were required to search for a potentially dangerous part using a static image under driving situations. The location of fixation point and the time series change of eye gaze were measured using an eye camera. In order to detect the difference of visual information processing among three groups above, an important area that the participants must pay attention to with the highest priority was set for each static image. The time until the eye gaze fixates to the important area, and the ratio of the fixation time to the total search time were detected. Using these measures, the difference of visual information processing among three groups was clarified. Moreover, for novice and non-licensed participants, it was also explored whether a lecture related to KYT would improve the efficiency of visual information processing. The time until the eye gaze fixates to the important area was longer for the non-licensed participants than for the experienced participants. The learning effect by means of a KYT lecture was also observed. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=HayamiTakehito en-aut-sei=Hayami en-aut-mei=Takehito kn-aut-name=早見武人 kn-aut-sei=早見 kn-aut-mei=武人 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=248 end-page=253 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevention of drowsy driving by means of warning sound en-subtitle= kn-subtitle= en-abstract= kn-abstract=Traffic accidents occur due to inattentive driving such as drowsy driving. A variety of support systems that make an attempt to prevent inattentive driving are under development. The development of a system to prevent drowsy driving using auditory or tactile alarm system is undertaken. It is essential to detect the low arousal state and warn drivers of such a state so that drowsy can be prevented. EEG (Electroencephalography) was used to evaluate how an arousal level degraded with time for eight participants under a low arousal level. Mean power frequency (MPF) was calculated to evaluate an arousal level. The value of MPF was compared between high and low arousal levels. The difference of arousal effect among four warning sounds was examined. As a result, there was no significant difference of arousal effect among four alarm sounds. The alarm sound was found to temporarily heighten participants' arousal level. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MatsudaYusuke en-aut-sei=Matsuda en-aut-mei=Yusuke kn-aut-name=松田佑介 kn-aut-sei=松田 kn-aut-mei=佑介 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=242 end-page=247 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Basic study on effectiveness of tactile interface for warning presentation in driving environment en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to get insight into the development of tactile interface for automobile warning system. In other words, it was investigated whether the important driving information in the right and left peripheral visual fields can be recognized faster using tactile warning system as compared with auditory warning system. The participants were required to simultaneously carry out a tracking task (main task), a switch pressing task such as selection of light-on function, and a judgment task of important information which randomly appeared to the right or left peripheral visual field. The tracking error, the number of lane deviation, the percentage correct of switch pressing, and the response time to right and left peripheral stimulus were measured. It was examined how age, the modality of alarm presentation (no alarm, auditory, and tactile), the addition of direction in alarm presentation, and the existence of disturbance sound, and the location of tactile sensor (steering or foot) affected the measures above. The young adults performed better than older adults. The response time was not affected by the modality of alarm presentation, and the disturbance sound. The addition of direction of alarm presentation affected the performance. The tactile sensor attached to the foot led to faster response than that attached to the steering wheel. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=TanakaKohki en-aut-sei=Tanaka en-aut-mei=Kohki kn-aut-name=田中弘毅 kn-aut-sei=田中 kn-aut-mei=弘毅 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=236 end-page=241 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of location of information presentation in pedestrian detection system on visibility and performance en-subtitle= kn-subtitle= en-abstract= kn-abstract=A few pedestrian warning systems for automobiles are in practical use. It has not been clarified where is best suited for the location of pedestrian information presentation. The most effective location of information presentation in pedestrian detection system was investigated. In other words, the location that assured the fastest cognition of pedestrian information was clarified. The locations of information presentation in pedestrian detection system were front glass, front display of cockpit module, and left side display of cockpit module (like car navigation system). The participants were required to pay attention to the predetermined front area as well as the randomly presented pedestrian information while carrying out a virtual driving task (tracking task) and a secondary switch pressing task such as selection of wiper function. We also investigated the effect of alarm sound presented to the participants together with the visual pedestrian information on the cognition time of pedestrian information. As a result, the front glass was most suitable for the presentation of pedestrian information. The presentation of pedestrian information to the front glass led to high visibility and faster pedestrian cognition time. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=AratamaShinsaku en-aut-sei=Aratama en-aut-mei=Shinsaku kn-aut-name=新玉晋作 kn-aut-sei=新玉 kn-aut-mei=晋作 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=182 end-page=185 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of State of Eye Movements before Saccade on Efficiency of Response to Stimulus - Comparison of Search Efficiency between Fixation and Smooth Pursuit Situations - en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, how the state of eye movement before saccade affected the response to a stimulus was explored. The state of eye movement before saccade was either smooth pursuit or fixation. The smooth pursuit was carried out both clockwise and counter-clockwise. Using an eye-tracking system, the eye movement during the experimental task was monitored. The response time to a stimulus was measured. On the basis of the eye movement data (coordinate), the eye movement velocity, the eye movement acceleration, and the latency of eye movement were obtained. When smooth pursuit was carried out before saccade, the response to a stimulus which appears as a result of saccade was faster. More concretely, the response time of smooth pursuit condition was faster than that of fixation condition. The latency of the smooth pursuit condition tended to be faster than that of the fixation condition. Some implications for the application of the results to the traffic safety or automotive ergonomics were given. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=HayamiTakehito en-aut-sei=Hayami en-aut-mei=Takehito kn-aut-name=早見武人 kn-aut-sei=早見 kn-aut-mei=武人 aut-affil-num=2 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=176 end-page=181 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Development of the Computer Aided Remanufacturing System (CARES) Part I: Software Development (Phase I) and a Simulation Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The environment bills that passed by the legislators triggered a new dimension towards the manufacturers to consider producing eco – friendly product.

In addition, the growth of remote shopping such as internet and catalog one, helps accelerate the decline of old shopping malls. However, these malls give the only one life-line to the elder and disabled population. In this paper, we discuss on the way of maintaining this life-line for elder and disabled one from the study of questionnaire surveys for visitors of two shopping mall in Wakamatsu-ward and Tobata-ward, Kitakyushu, the gate way city to Kitakyushu in Fukuoka Prefecture.

Production and inventory planning must reflect this property for cost effectiveness and optimization of resources. This paper presents two production-inventory models for perishable seasonal products that minimize total inventory costs. The models obtains optimal production run time and optimal production quantity for cases when the production rate is constant and when it is allowed to vary with demand. The products are assumed to deteriorate at an exponential rate and demand for them follows a three-phase ramp type pattern during the season. Numerical examples and sensitivity analysis are carried out. Production run time and production quantity obtained by the model were found to be independent of cost parameters. The variable production rate strategy was also found to give lower inventory costs and production quantity than the constant production rate strategy. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=IbraheemAbdul kn-aut-sei=Ibraheem kn-aut-mei=Abdul aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=158 end-page=163 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An optimal EOQ model for perishable products with varying demand pattern en-subtitle= kn-subtitle= en-abstract= kn-abstract=The demand pattern for most perishable products varies during their life cycle in the market. These variations must be properly reflected in inventory management in order to prevent unnecessary stock-out or excess inventory with associated increase in cost. In this paper, a multi-period economic order quantity (EOQ) model for managing the inventory of perishable items having varying demand pattern is presented. The model was formulated using a general ramp-type demand function that allows three-phase variation in demand pattern. These phases represent the growth, the steady and the decline phases commonly experienced by the demand for most products during their life cycle in the market. The model generates replenishment policies that guarantees optimal inventory cost for all the phases. Numerical experiments and sensitivity analysis were carried out to demonstrate the suitability of the model for a wide range of seasonal products. Result of the experiments revealed that the points at which demand pattern changes are critical points in managing inventory of products with ramp type demand. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=IbraheemAbdul kn-aut-sei=Ibraheem kn-aut-mei=Abdul aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=2009 cd-vols= no-issue=1 article-no= start-page=348 end-page=353 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Drowsiness by HRV Measures - Proposal of prediction method of low arousal state - en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to propose a useful prediction method of drowsy state of drivers, so that the result is applicable to the development of ITS (Intelligent Transportation System) that can warn drivers of their low arousal state and to prevent driving under low arousal level from occurring. The EEG (electroencephalography) and ECG (electrocardiography) during a monotonous task was measured, and it was investigated how these measures change under the low arousal (drowsy) state. The EEG measurement was added to in order to monitor arousal level more the time series of mean power frequency of EEG was plotted on X-bar control chart. Heart rate variability (HRV) measure RRV3 were derived on the basis of R-R intervals (interbeat intervals) obtained from ECG. Using a Bayesian probability, we tried to predict the timing when the participant actually felt drowsy. As a result, the prediction accuracy differed by the state of participant. When the drowsiness of participant was remarkable, the prediction method was effective to some extent. On the other hand, the proposed method could not predict the drowsy state reliably when the participant did not feel drowsiness to a larger extent. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=HiramatsuYasutaka en-aut-sei=Hiramatsu en-aut-mei=Yasutaka kn-aut-name=平松靖隆 kn-aut-sei=平松 kn-aut-mei=靖隆 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=7 article-no= start-page=2443 end-page=2456 dt-received= dt-revised= dt-accepted= dt-pub-year=1958 dt-pub=1958 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Medullary Blood Vessel Construction and Canals of Cartilage in Human Foetus Long Bones Part 2.

Metaphyseal vessels appear in the latter half of foetal life and these metaphyseal arteries are anastomosed with branches of diaphyseal arteries. 7. Canals of cartilage can be seen entering into proximal and distal epiphysis from the beginning of the fourth embryonic month. 8. In the last month of foetal life an ossification center can be recognized in the distal epiphysis, and a part of canals of cartilage is connected with the ossification center. en-copyright= kn-copyright= en-aut-name=MurataSeizo en-aut-sei=Murata en-aut-mei=Seizo kn-aut-name=村田精三 kn-aut-sei=村田 kn-aut-mei=精三 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=551 end-page=575 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Prevention of Side-Effects of the Anticancer Agent kn-title=制癌剤の副作用防止に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Preventive measure of the side-effects of an anticancer agent, Mitomycin-C (MMC), was investigated on Ehrlich tumor mice, by using several agents which had originally no tumoricidal effects except last one: such as orotic acid (OA), chloroquine orotate (QO), magnesium chloride (Mg), Sarvinal (SV), dihydrostreptomycin (SM), and so-called OX-substance (OX; unsaturated fatty acid fraction extracted from the liver of X-Ray irradiated rabbit). Results obtained were as follows. 1. Mg had a most preventive effect on the reduction of WBC due to MMC, following by SM, CO and SV. 2. On the fluctuation of RBC, SM, Mg, OA and CO showed better results. 3. No agents tested were effective on the prevention of reduction in platelets. 4. No unwilling decrease in tumor-effects were noted in these agents. 5. Survival time was markedly extended in case of using SM. Summarizing the results obtained above, streptomycin was a most useful agent for the prevention of side-effects of Mitomycin-C. Under the fundamental investigation, streptomycin was clinically used in case of giving Mitomycin-C, and the side-effects were remarkably reduced as seen in the experiment. Further studies would have to be continued on the other anticancer agents. en-copyright= kn-copyright= en-aut-name=MurataMasahiko en-aut-sei=Murata en-aut-mei=Masahiko kn-aut-name=村田雅彦 kn-aut-sei=村田 kn-aut-mei=雅彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=204 end-page=209 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Care for Home-bound Older Adults and Revitalization of Local Shopping Arcade en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Japanese Ministry of Internal Affairs and Communications announced, on Respect-for-the Aged Day in September, 2005, that the population over 65 is over 20 % of the nation’s total population. The Ministry also announced on June 1, 2006, that the special total birth rate in Japan recorded the lowest value of 1.25. If the birth rate continues to decrease faster than estimated, the ratio of older adults to the nation’s total population will increase faster than expected. As new housing and large-scaled supermarkets are planned and constructed in the suburbs, older adults, the poor and the disabled people who cannot afford to drive for utilizing suburb supermarkets are forced into old inactive residential area and shopping arcade. Older adults hope to communicate with others, which can be facilitated by advanced technology. The case studies in this study show that older adults can satisfy such needs by communicating with shop owners in local shopping arcade. The secret for the revitalization of local shopping arcade lies in the care for home-bound older adults. We recommend a concept of cozy compact city where home-bound older adults can actively enjoy their lives in and out of their home and the local shopping arcade can be revitalized. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=MatsuoTetsuko kn-aut-sei=Matsuo kn-aut-mei=Tetsuko aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences affil-num=2 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=198 end-page=203 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A PERISHABLE INVENTORY MODEL WITH UNKNOWN TIME HORIZON en-subtitle= kn-subtitle= en-abstract= kn-abstract=Traditionally, the time (planning) horizon over which the inventory for a particular item will be controlled is often assumed to be known (finite or infinite) and the total inventory cost is usually obtained by summing up the cost over the entire time horizon. However, in some inventory situations the period over which the inventory will be controlled are difficult to predict with certainty, as the inventory problems may not live up to or live beyond the assumed planning horizon, thereby affecting the optimality of the model. This paper presents a deterministic perishable inventory model for items with linear trend in demand and constant deterioration when time horizon is unknown, unspecified or unbounded. The heuristic model obtains replenishment policy by determining the ordering schedule to minimize the total cost per unit time over the duration of each schedule. A numerical example and sensitivity analysis are given to illustrate the model. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=A.I..ABDUL kn-aut-sei=A.I.. kn-aut-mei=ABDUL aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=A.E.OLULEYE kn-aut-sei=A.E. kn-aut-mei=OLULEYE aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences affil-num=2 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences affil-num=3 en-affil= kn-affil=University of Ibadan END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=191 end-page=197 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of Instruction using Electronic Circuit Simulation Software en-subtitle= kn-subtitle= en-abstract= kn-abstract=Traditional teaching (lecturing) method on the design of electronic circuit provides learners with little satisfaction, because they cannot check and confirm the validity of electronic circuit they have designed. A better way to acquire design skills is to actually make the designed electronic circuit and test the validity of design. In spite of the usefulness of such a practical approach, it has a disadvantage that there is only limited time for teaching (lecturing) and it is difficult to fabricate electronic circuit, perform electronic measurement, and test the validity of design in the limited lecture period. An alternative to overcome these disadvantages is to use simulation software that enables learners (students) to operate functionally the designed electronic circuit and verify the appropriateness of design. The aim of this study was to examine the usefulness of simulation approach and clarify some problems related to such an approach. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=OhtaYukio kn-aut-sei=Ohta kn-aut-mei=Yukio aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences affil-num=2 en-affil= kn-affil=Department of Intelligent Mechanical Systems, Division of Industrial Innovation Sciences END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=127 end-page=132 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of Eye-Gaze Input System -Identification of Conditions that Assures High Pointing Accuracy and Movement Directional Effect- en-subtitle= kn-subtitle= en-abstract= kn-abstract=The condition under which high accuracy is assured when using an eye-gaze input system was identified. It was also investigated how direction of eye movement affected the performance of an eye-gaze input system. Here, age, the arrangement of targets (vertical and horizontal), the size of a target, and the distance between adjacent rectangles were selected as experimental factors. The difference of pointing velocity between a mouse and an eyegaze input system was larger for older adults than for young adults. Thus, an eye-gaze input system was found to be effective especially for older adults. An eye-gaze input system might compensate for the declined motor functions of older adults. The pointing accuracy of an eye-gaze input system was higher in horizontal arrangement than in vertical arrangement. The distance between targets of more than 20 pixels was found to be desirable for both vertical and horizontal arrangements. For both the vertical and horizontal arrangements, the target size of more than 40pixels led to higher accuracy and faster pointing time for both young and older adults. For both age groups, it tended that the pointing time for the lower direction was longer than that for other directions. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MiyakeTakashi en-aut-sei=Miyake en-aut-mei=Takashi kn-aut-name=三宅貴士 kn-aut-sei=三宅 kn-aut-mei=貴士 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=121 end-page=126 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usability of Site Map in Web Design – Design of Site Map that is Friendly to Older Adults- en-subtitle= kn-subtitle= en-abstract= kn-abstract=The information or data for Web page design that is useful, in particular, to older adults was provided in this study. The proper design of site map is necessary to enhance the usability and reduce the number of getting lost in Web navigation especially for older adults. However, no design guideline on what site map is proper exists. The usability of six types of site maps was compared as a function of age. The six types of site maps included (1) vertical tree type, (2) horizontal tree type (A), (3) horizontal tree type (B), (4) table type, (5) radial type, and (6) itemized type. The usability was evaluated using search time, subjective rating of usability, and eye movement characteristics (fixation duration and fixation number). The age affected the evaluation measures. The horizontal type (B) was found to lead to faster search time and fewer fixation numbers. Moreover, this type of site map was found to make the difference of search time, fixation number, and fixation duration between young and older adults smaller. The result indicated that the vertical arrangement of site map, especially horizontal type (B) was proper for both young and older adults, and this should be incorporated into the Web page design guidelines. The results can be utilized as a universal design guideline for providing a site map that is friendly to both young and older adults. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=117 end-page=120 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Shape of pen on Usability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Using electromyography (EMG) analysis and psychological rating, the usability of pen was evaluated. The experimental factors wewre the pen diameter (three levels:8mm, 11mm, and 13.8mm). The length of pen tip was fixed to 14mm. Surface EMG was recordes from extensor digitorum and flexxor digitorum superficialis. The EMG before and after a long-hour writing task was measured to evaluate the fatigue of forearm using % MVC (Mean Voluntary Contraction), mean power frequency (MPF) and psychological rating on usability. Concerning % MVC and MPF, the difference before and the experimental task were used for the evaluation. The evaluation value corresponded to subtraction of value after the experimental task from that before the experimental task. As a result of a one-way (pen diameter) ANOVA, no significant main effects of pen diameter were for both EMG evaluation measures. As for the psychological rating on usability, Kruscal-Wallis non-parametric test was carried out. The psychological rating on ease of grip revealed a significant main effect of pen diameter. A pen with a diameter of 11mm was found to have a significant higher rating score. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MizushimaKensuke en-aut-sei=Mizushima en-aut-mei=Kensuke kn-aut-name=水島健介 kn-aut-sei=水島 kn-aut-mei=健介 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University en-keyword=universal design kn-keyword=universal design en-keyword=usability kn-keyword=usability en-keyword=EMG kn-keyword=EMG en-keyword=pen diameter kn-keyword=pen diameter en-keyword=length of pen tip kn-keyword=length of pen tip en-keyword=psychological rating kn-keyword=psychological rating END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=111 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimal Slope of Touch Panel -Comparison between Young and Older Adults- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Touch panels are becoming increasingly common alternatives to traditional indirect devices such as mouse. However, older adults are not willing to utilize touch-panel based ATM or ticket machines, because they feel that using ATM properly is too difficult and annoying for them. The aim of this study was to identify an optimal slope of touch panel interface. Whether using a direct input device by older adults would lead to smaller difference of performance between preferred and non-preferred hands was also examined. For both young and older adults, the slope conditions of 30, 45, and 60 degrees, and the target size of 60 x 60 pixels were found to lead to higher performance. With the increase of movement distance d, the movement velocity tended to increase for both age groups. The difference of movement velocity between young and older adults tended to increase with the increase of movement distance d. The difference of performance between nonpreferred and preferred hands was smaller relative to their young counterparts. Moreover, the difference of performance between young and older adults was smaller when using a touch panel than when using a mouse. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=TakahashiRina en-aut-sei=Takahashi en-aut-mei=Rina kn-aut-name=高橋里奈 kn-aut-sei=高橋 kn-aut-mei=里奈 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=103 end-page=110 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Web Design that is Friendly to Older Adults – Effects of Perceptual, Cognitive and Motor Functions and Display Information on Web Navigation Time – en-subtitle= kn-subtitle= en-abstract= kn-abstract=Older internet users are increasing more and more world widely. The information accessibility standard for Web contents (JIS X 8341-3) had been established. Although many researchers are pursuing the usability of Web site, we cannot design a usable Web site only by improving Web pages. One of the reasons is inferred that we didn’t consider perceptual, cognitive, and motor functions especially of older adults in the design of Web pages. The aim of this study was to propose a method to evaluate perceptual, cognitive, and motor ability and to explore the effect of perceptual, cognitive and motor abilities, and display information on Web navigation. We proposed a method to calculate display information on the basis of number of links. It was explored how display information, age, and the test score of perceptual, cognitive, and motor abilities influenced Web navigation time. This effect was examined using a multiple regression analysis. Display information influenced Web navigation performance for both young and older adults. The more the quantity of display information was, the longer the Web navigation time was. In addition to this tendency, the depth of display layer was found to affect the Web navigation time especially for older adults. We found that the perceptual, cognitive, and motor abilities of older adults, in particular, the spatial memory, spatial rotation ability, and mouse operation ability, led to longer Web navigation time. These results implies the necessity of designing Web site for older adults that considers the decline of perceptual, cognitive, and motor ability. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=TakahashiRina en-aut-sei=Takahashi en-aut-mei=Rina kn-aut-name=高橋里奈 kn-aut-sei=高橋 kn-aut-mei=里奈 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=99 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Drowsiness by HRV Measures - Basic Study for Drowsy Driver Detection - en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to identify a useful measure to estimate an arousal level of drivers, to apply the result to develop ITS (Intelligent Transportation System) that can warn drivers of their low arousal state and to prevent driving under low arousal level from occurring and contribute to the reduction of traffic accidents. The EEG (electroencephalography) and ECG(electrocardiography) during a monotonous task was measured, and it was investigated how these measures change under the low arousal (drowsy) state. The time series of mean power frequency of EEG was plotted on X-bar control chart. Heart rate variability (HRV) measures RRV3 and RRV8-3 were derived on the basis of R-R intervals (interbeat intervals) obtained from ECG.

A dual-task experimemt was conducted in which the primary task was first-irder tracking. The secondary tasks included control of an air conditioner, the operation of a radio, and the operation of a CD/MD, by means of a steering wheel mounted swich. The switch was either vertical or cross arrangement. In both-hands switch arrangement condition, the operation was carried out with two hands using both left vertical switch and right cross switch. In one-hand swith arrangement condition, the operation was carried out with only one hand using either left or right cross switch. The display was arranged in front of a participant. The display form was either left or right display. The viewing distance conditions were 60, 80, and 100cm. When the right display form was used, both one-hand (using only right cross switch) were selected. When the left display form was used, both one-hand (using only left cross swith) and two-hand arrangements (using both left vertical and right cross switch) were selected. As predicted, age affected the performance measures ( percentage correct, task completion time, and tracking error). The viewing distance also affected performance (percentage correct), Both display form and switch arrangement also affected performance (task completion time). Such results should be taken into account when designing display and control systems in man-vehicle systems. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=YamaguchiSatoshi en-aut-sei=Yamaguchi en-aut-mei=Satoshi kn-aut-name=山口智司 kn-aut-sei=山口 kn-aut-mei=智司 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=83 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Automotive Control-Display System by means of MentalWorkload en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of age, task difficulty on performance and mental workload were discussed in order to provide design guideline of automobile display that is friendly to older adults from the viewpoints of mental attention, speed and accuracy. A dual-task experiment was conducted in which the primary task was first order tracking. The secondary tasks included selection of function (easy condition), and control of an air conditioner, the operation of a radio, and the operation of a CD/MD (difficult condition), by means of a steering wheel mounted switch. The display was arranged in front of a participant. Age affected the performance measures and heart rate variability (HRV). As for the young adults, the task completion time did not differ significantly among easy and difficult (one-, two-, and three-layered) conditions. The performance of older adults was affected by task difficulty. The HRV measures such as CV (coefficient of variance) and RRV8-3 during the task showed different tendency between young and older adults. As for the young group, the HRV measures did not differ significantly between the four task levels (easy, one-, two-, and three-layered). This confirmed that the task difficulty did not induce different mental workload to young adults. On the other hand, as for the older adults, the HRV measures tended to increase with the increase of task difficulty. Although it appears that mental workload was lessened with the increase of task difficulty, such an interpretation was contradictory to the results on performance. This phenomenon was interpreted that the difficult task condition was overloaded for older adults, and was beyond the limit of mental effort. Based on the results, it could be concluded that the difficult task condition is not proper for older adults. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=77 end-page=82 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of the evaluation system for automobile remanufacturing en-subtitle= kn-subtitle= en-abstract= kn-abstract=By 2015, the EU directives required the automobile manufacturers to produce a vehicle that contains reusable and / or recoverable parts at least 95% of total weight. In the developed countries, the legislative issue the take – back policy which requires the manufacturers to consider the end – of – life (EOL) of their products at early design stage. The goal of this paper is to propose a framework of development methodology that focuses on integrated design for remanufacturing evaluation system. This system supports the automobile product design and development at the early design phase. The proposed method is divided into two phases. The first phase aims to identify the suitable EOL process. The second phase aims to verify the most economical EOL process. The proposed method incorporates the Case base Reasoning [CBR] into the remanufacturing techniques. It is expected that the proposed method can provide the EOL with decision support during designing the automobile parts at the early design stage. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=GhazalliZakri kn-aut-sei=Ghazalli kn-aut-mei=Zakri aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=71 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of vehicle display information and switch type on usability -Comparison between young and older adults- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, in-vehicle highly intelligent information devices are rapidly widespread. Under such circumstances, the accurate evaluation of the effect of display information and switch type on driving performance is important in order to develop in-vehicle information devices that do not menace the safety. In this article, we present a basic idea to estimate properly the effect of the vehicles display information and the switch system on driving performance. We compared the index such as mean task completion time, subjective rating on usability, tracking error, and NASA-TLX workload between young and older adults. The results suggest that young will be better than older adults at both abilities on processing displayed information and operating the switch. We were found that there was a significant interaction between the switch types and installation location. On the other hand, the displayed information did not affect the performance. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=WangShuguang kn-aut-sei=Wang kn-aut-mei=Shuguang aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Human Error Management Paying Emphasis on Decision Making and Social Intelligence -Beyond the Framework of Man-Machine Interface Design- en-subtitle= kn-subtitle= en-abstract= kn-abstract=How latent error or violation induces a serious accident has been reviewed and a proper addressing measure of this has been proposed in the framework of decision making, emotional intelligence (EI) and social intelligence (SI) of organization and its members. It has been clarified that EI and SI play an important role in decision making. Violations frequently occur all over the world, although we definitely understand that we should not commit violations, and a secret to prevent this might exist in the enhancement of both social intelligence and reliability. The construction of social structure or system that supports organizational efforts to enhance both social intelligence and reliability would be essential. Traditional safety education emphasizes that it is possible to change attitudes or mind toward safety by means of education. In spite of this,accidents or scandals frequently occur and never decrease. These problems must be approached on the basis of the full understanding of social intelligence and limited reasonability in decision making. Social dilemma (We do not necessarily cooperate in spite of understanding its importance, and we sometimes make decision not to select cooperative behavior. Non-cooperation gives rise to a desirable result for an individual. However, if all take non-cooperative actions, undesirable results are finally induced to all.) must be solved in some ways and the transition from relief (closed) society to global (reliability) society must be realized as a whole. New social system, where cooperative relation can be easily and reliably obtained, must be constructed to support such an approach and prevent violation-based accidents. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1267 end-page=1286 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=High-power scanning electron microscopy of senile plaques, neurofibrillary tangles, and Pick bodies kn-title=老人斑,Alzheimer 神経原線維変化,Pick 嗜銀球の超高倍率走査電顕的観察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Senile plaques, neurofibrillary tangles, and Pick bodies were examined by modified scanning electron microscopy from a low-power to an ultra high-power range. The amyloid core of the typical plaques was found to be composed of radially arranged rod-shaped components, which were made up of dense aggregation of meandering moniliform amyloid filaments about 15 nm in diameter. Bands with a mesh-like structure were observed outside the crown around the core. The compact plaques were nearly identical to the core alone of the typical plaques. The primitive plaques as a whole were analogous to the mesh-like structure around the typical plaques, and they both contained aggregates of filaments closely resembling amyloid fibers. In neurofibrillary tangles, the flamed shape stretched straight to the peripheries, the globosed shaped formed vortices, and only bundles of parallel filaments were observed. PHFs that constituted these structures were 25-30 nm in diameter, and many appeared constricted to a diameter of about 15 nm by rotating 180° to the left at a cycle of 70-80 nm. In Pick bodies, filaments were interwoven and formed a mesh-like structure, numerous granules were attached the filaments. Some filaments were large, being 20-30 nm in diameter, others were thin, being about 15nm in diameter. en-copyright= kn-copyright= en-aut-name=KuyamaKeisuke en-aut-sei=Kuyama en-aut-mei=Keisuke kn-aut-name=久山圭介 kn-aut-sei=久山 kn-aut-mei=圭介 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=Senile Plaque kn-keyword=Senile Plaque en-keyword=Alzheimer's neurofibrillary changes kn-keyword=Alzheimer's neurofibrillary changes en-keyword=Pick body kn-keyword=Pick body en-keyword=scanning electron microscopy kn-keyword=scanning electron microscopy END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=1-2 article-no= start-page=165 end-page=176 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=Magnetic resonance image database system and its clinical applications kn-title=MR 画像データベースシステムの開発とその臨床応用に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A magnetic resonance (MR) image detabase system has been developed.

The average follow up time was 8 years and 5 months, ranging from 5 to 17 years. Except in 26 cases of death or 9 incomplete histories at the follow-up, 62 cases were investigated both clinically and radiologically. For the operations, two types of prostheses (Charnley and C-Muller ) were used. According to the Japan Orthopaedic Association (JOA) hip score, the preoperative score improved from 32.9 to 57.1 points at the final postoperative evaluation. In the radiological assessment using the method by Nagaya and Uno, a clear zone was seen around the acetabular cup in 82.2% of the hips and around the femoral stem in 53.2%. Rate of loosening corresponding to stage Ⅲ and Ⅳ was 20.2% in the acetabular side and 32.9% in the femoral side. Charnley-type group was better than C-Muller type both in clinical and radiological assessments. Twelve cases had lost walking ability. As postoperative complications, deep infections occurred in 4 hips, femoral shaft fracture in 4 hips, dislocation in 1 hip and revision due to aseptic loosening in 4 hips. THR may be useful for rheumatoid patients and improve the quality of life in the case of long-term disease if careful pre-and post-operative care is provided. en-copyright= kn-copyright= en-aut-name=OosakiKazuhiko en-aut-sei=Oosaki en-aut-mei=Kazuhiko kn-aut-name=大﨑和彦 kn-aut-sei=大﨑 kn-aut-mei=和彦 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=慢性関節リウマチ kn-keyword=慢性関節リウマチ en-keyword=全人工股関節置換術 kn-keyword=全人工股関節置換術 en-keyword=長期追跡調査 kn-keyword=長期追跡調査 en-keyword=合併症 kn-keyword=合併症 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=3-4 article-no= start-page=297 end-page=310 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=Clinical and histological studies on steroid-induced avascular necrosis of the femoral head, especially in ststemic lupus erythematosus kn-title=ステロイド性大腿骨頭壊死症の病態に関する研究―全身性エリテマトーデス(SLE)を中心に― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clinical and radiological studies were performed on avascular necrosis of the femoral head (ANF) in 220 hips 140 patients including 51 hips of 28 patients with systemic lupus erythe-matosus (SLE group). Sixty-nine hips of 41 patients wee treated with corticosteroid adminis-tration (S group) and 100 hips of 71 patients without corticosteroid administration (Non-S group). All patients with SLE were treated with corticosteroid adminstration. Thirty-one femoral heads (11 heads of SLE group, 9 heads of S group and 11 heads of Non-S group) were resected at operations nad studied histologically. Seventy-seven hips at an early stage showed that collapse of the femoral heads occurred in 80% without 3 years and no differences were found among these group. In the SLE group, bilateral involvement, multiple bone necrosis and predilection for young females were apparent. Collapse of the femoral head and subcapital fractures were more frequently seen in the SLE group. Histologically, almost all heads even in the SLE group showed repair process such as enchondral ossification and appositional bone formation, while the heads with subcapital fracture showed no such no such changes. en-copyright= kn-copyright= en-aut-name=UsuiMasaaki en-aut-sei=Usui en-aut-mei=Masaaki kn-aut-name=臼井正明 kn-aut-sei=臼井 kn-aut-mei=正明 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=大腿骨頭壊死症 kn-keyword=大腿骨頭壊死症 en-keyword=全身性エリテマトーデス(SLE) kn-keyword=全身性エリテマトーデス(SLE) en-keyword=病態 kn-keyword=病態 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=2008 dt-pub=20080930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=FAKの局在性と大腸癌の癌化との関連 kn-title=Localization of FAK is related with colorectal carcinogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MurataToshihiro en-aut-sei=Murata en-aut-mei=Toshihiro kn-aut-name=村田年弘 kn-aut-sei=村田 kn-aut-mei=年弘 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 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=2008 dt-pub=20080930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=単球におけるLPS誘導性の新規TNF-α転写制御因子に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MurataHiromi en-aut-sei=Murata en-aut-mei=Hiromi kn-aut-name=村田裕美 kn-aut-sei=村田 kn-aut-mei=裕美 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=1-2 article-no= start-page=73 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation of anthracycline-anthraquinone analogues in the treatment of lung cancer using colony assay Part 1.

The human lung cancer cell lines tested were EBC-1, an epidermoid cancer cell line, ABC-1, an adenocarcinoma cell line, and SBC-1, -2, and -3, small cell cancer cell lines. In general, the EBC-1 established from a patient tumor showing resistance to ADM was the least sensitive to the drugs tested, and SBC-3 established from a patient tumor with no prior chemotherapy was the most sensitive to the drugs. In antitumor activity, both ACR and THP-ADM appeared to be superior to ADM and MIT, suggesting the clinical usefulness of these drugs in the treatment of lung cancer. en-copyright= kn-copyright= en-aut-name=NumataTakeyuki en-aut-sei=Numata en-aut-mei=Takeyuki kn-aut-name=沼田健之 kn-aut-sei=沼田 kn-aut-mei=健之 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=肺癌細胞株 kn-keyword=肺癌細胞株 en-keyword=colony assay kn-keyword=colony assay en-keyword=anthracycline kn-keyword=anthracycline en-keyword=anthraquinone kn-keyword=anthraquinone END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=11-12 article-no= start-page=343 end-page=351 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=19970228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A causal model analysis of the quality of life in patients with cerebrovascular diseases at home kn-title=パス解析モデルによる在宅脳血管障害患者の QOL の解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this study was to elucidate the factors of subjective quality of life (QOL) for the patients with cerebrovascular diseases and to investigate the usefulness of path analysis as an analystic method for the subjective QOL. A separate factor analysis was carried out for the 67 patients using the questionnaire developed by a research team of the Ministry of Health and Welfare in 1992. As a result, three fectors could be confirmed. They were feeling of satisfaction, sense of psychological security, and volision and vitality. In addition, the internal consistency of scaling observed suggests the validity of the evaluation, using these three factors, of subjective QOL of those patients. As a result of effect of extended ADL on the feeling of satisfaction, the sense of psychological security and the volision and vitality, the degree of the direct effects and that of the indirect effects through depressive state could be clarified on these three factors. These results suggest the usefulness of path analysis as the analystic method for the subjectice QOL of patients with cerebrovascular diseases at home. en-copyright= kn-copyright= en-aut-name=KagawaKoujiro en-aut-sei=Kagawa en-aut-mei=Koujiro kn-aut-name=香川幸次郎 kn-aut-sei=香川 kn-aut-mei=幸次郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 en-keyword=cerebrovascular disease kn-keyword=cerebrovascular disease en-keyword=QOL kn-keyword=QOL en-keyword=extended ADL kn-keyword=extended ADL en-keyword=depression kn-keyword=depression en-keyword=path analysis kn-keyword=path analysis END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=751 end-page=756 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case report of esophageal cyst kn-title=食道囊腫の1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Esophageal cyst is a relatively rare disease and about 91 cases have been reported in Japan.

We performed esophagography, endoscopy, endoxcopic echography, CT and MRI and found a cystic lesion in the lower esophagus. We made the diagnosis of an esophageal cyst and performed operation. The tumor was in the esophageal muscle but did not have a commissure to the esophageal lumen. We extirpated it with esophageal muscle and repaired the muscle defect with diaphragma. This tumor, 7.5×5.0cm in size, was a monolocular cyst and contained brown muddy material. Microscopic findings revealed a ciliated columnar epithelium and squamous epithelium in the cyst wall but cartilage was not found. The cyst was covered with double smooth muscle layers. It was difficult to differentiate an esophageal cyst from a paraesophageal bronchogenic cyst but these histological findings suggested that this cyst was an esophageal cyst. en-copyright= kn-copyright= en-aut-name=IshiiYasunori en-aut-sei=Ishii en-aut-mei=Yasunori kn-aut-name=石井泰則 kn-aut-sei=石井 kn-aut-mei=泰則 aut-affil-num=1 ORCID= en-aut-name=InoueFumiyuki en-aut-sei=Inoue en-aut-mei=Fumiyuki kn-aut-name=井上文之 kn-aut-sei=井上 kn-aut-mei=文之 aut-affil-num=2 ORCID= en-aut-name=BanHidetoshi en-aut-sei=Ban en-aut-mei=Hidetoshi kn-aut-name=伴秀利 kn-aut-sei=伴 kn-aut-mei=秀利 aut-affil-num=3 ORCID= en-aut-name=KamikawaYasuaki en-aut-sei=Kamikawa en-aut-mei=Yasuaki kn-aut-name=上川康明 kn-aut-sei=上川 kn-aut-mei=康明 aut-affil-num=4 ORCID= en-aut-name=OritaKunzo en-aut-sei=Orita en-aut-mei=Kunzo kn-aut-name=折田薫三 kn-aut-sei=折田 kn-aut-mei=薫三 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=食道囊腫 kn-keyword=食道囊腫 en-keyword=esophageal cyst kn-keyword=esophageal cyst en-keyword=気管支食道囊腫 kn-keyword=気管支食道囊腫 en-keyword=bronchial-esophageal cyst kn-keyword=bronchial-esophageal cyst en-keyword=foregut cyst kn-keyword=foregut cyst END start-ver=1.4 cd-journal=joma no-vol=110 cd-vols= no-issue=7-10 article-no= start-page=107 end-page=114 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19981030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Case report of a gastric glomus tumor kn-title=胃癌を伴った胃グロームス腫瘍の1例―本邦報告例の文献的考察― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The patient was a 67-year-old man who vomitted blood during therapy while hospitalized due to an asthma attack.

Children whose body mass index (BMI) was 22 or higher were considered obese. The percentate of obese children was 5.7 in Shengyang and 5.4 in Okayama. Multiple logistic regression analysis of dietary patterns and life styles to explain childhood obesity in both countries showed the importance of consuming large amounts of grain products, potatoes, sugar, and oily foods as factors related to chilihood obesity. Physical activity has also been shown to be negatively and significantly associated with childhood obesity. Daily intake of enetgy, carbohydrate, and fat among obese children was significantly greater than those among nonobese children. The length of time spent watching television among the Japanese children was found to contribute to childhood obesity. en-copyright= kn-copyright= en-aut-name=WangZhuan en-aut-sei=Wang en-aut-mei=Zhuan kn-aut-name=王専 kn-aut-sei=王 kn-aut-mei=専 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=児童肥満 kn-keyword=児童肥満 en-keyword=体格指数 (BMI) kn-keyword=体格指数 (BMI) en-keyword=生活習慣 kn-keyword=生活習慣 en-keyword=日中比較 kn-keyword=日中比較 END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=3-8 article-no= start-page=29 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=20000831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=MRI of the knee before and after arthroscopic synovectomy in patients with rheumatoid arthritis kn-title=鏡視下滑膜切除術を行った慢性関節リウマチの膝MRI en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effectiveness of arthroscopic synovectomy (A-S) for the knee of rheumatoid arthritis (RA) patients was assesssd by comparing the severity of synovial proliferation on MRI before and after the surgery. Twenty-five patients (30 knees) were studied. The mean duration of RA was 6 years and 7 months and the mean age at the time of A-S was 49.0 years. The mean follow-up period was 19 months (range:6-39 months). The preoperative Larsen's classification from grade Ⅰto Ⅳ was 8, 13, 6, and 3 knees, resectively. Synovial proliferation was evaluated by the modified Takeuchi's classification (MRI score). The MRI score was investigated in relationships with the radiographic grade, wet weight of excised tissue, treatment score for RA knees of the Japanese Orthopaedic Association (JOA score), and the CRP value. The MRI score, JOA score, and CRP all significantly improved during follow-up. The radiographic grade showed less progression, the JOA score improved more, and CRP was lower during follow-up in patients with a postoperative MRI score less than 5. The wet weight of excised tissue showed no related with the MRI score. These results suggest that the effectiveness of A-S can be determined by evaluation of improvement of the MRI score. en-copyright= kn-copyright= en-aut-name=KatohYasuyuki en-aut-sei=Katoh en-aut-mei=Yasuyuki kn-aut-name=加藤泰之 kn-aut-sei=加藤 kn-aut-mei=泰之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部整形外科学講座 en-keyword=Rheumatoid arthritis kn-keyword=Rheumatoid arthritis en-keyword=Knee kn-keyword=Knee en-keyword=Arthroscopic synovectomy kn-keyword=Arthroscopic synovectomy en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging 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=2008 dt-pub=20080325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ポリエチレンイミンカチオン化を用いたタンパク質細胞内導入技術の開発と細胞機能の人工制御への応用 kn-title=Development of a protein transduction technology using polyethylenimine-cationization, and application to regulation of cellular function en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MurataHitoshi en-aut-sei=Murata en-aut-mei=Hitoshi kn-aut-name=村田等 kn-aut-sei=村田 kn-aut-mei=等 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 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=2007 dt-pub=20070630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=脂肪肝マウスの肝切除後の再生障害のメカニズム kn-title=Mechanism of impaired regeneration of fatty liver in mouse partial hepatectomy model en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MurataHiroshi en-aut-sei=Murata en-aut-mei=Hiroshi kn-aut-name=村田宏 kn-aut-sei=村田 kn-aut-mei=宏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=11 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20040701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ウンシュウミカンにおける特殊肥料の施用効果の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=桑木信輔 kn-aut-sei=桑木 kn-aut-mei=信輔 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大平猪一朗 kn-aut-sei=大平 kn-aut-mei=猪一朗 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高畑真澄 kn-aut-sei=高畑 kn-aut-mei=真澄 aut-affil-num=3 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name=村田芳行 kn-aut-sei=村田 kn-aut-mei=芳行 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=多田幹郎 kn-aut-sei=多田 kn-aut-mei=幹郎 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=株式会社バイオバンク affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=119 end-page=125 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Upconversion property and light scattering in Tm(3+)-doped glass-ceramics kn-title=Tm(3+)含有結晶化ガラスのアップコンバージョン特性と光散乱 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glass-ceramics containing Pb(x)Cd(1-x)F(2) microcrystallites were prepared through heat treatment of Tm(3+)/Yb(3+)doped SiO(2)-Al(2)O(3)-PbF(2) glasses. The crystallite size was controlled by varying the heat-treatment time. By changing glass composition, two types of strong optical scattering, Rayleigh and Mie scattering modes were observed for the glass ceramics. In the case of Rayleigh scattering, the scattering region expanded to the long-wavelength side with increasing the heat-treatment time. On the other hand, in the case of Mie scattering, the region were hardly dependent on wavelength, and visible light was widely scattered. It was argued that the different scattering phenomena were caused by the different size of the crystallites or their morphogical texture. Furthermore, the glass-ceramics with strong optical scattering showed higher upconversion fluorescence intensity than the matrix glass. The mechanisms for the enhanced upconversion due to the scattering were discussed. en-copyright= kn-copyright= en-aut-name=MiuraYoshinari en-aut-sei=Miura en-aut-mei=Yoshinari kn-aut-name=三浦嘉也 kn-aut-sei=三浦 kn-aut-mei=嘉也 aut-affil-num=1 ORCID= en-aut-name=DingYong en-aut-sei=Ding en-aut-mei=Yong kn-aut-name=丁勇 kn-aut-sei=丁 kn-aut-mei=勇 aut-affil-num=2 ORCID= en-aut-name=MurataTakashi en-aut-sei=Murata en-aut-mei=Takashi kn-aut-name=村田隆 kn-aut-sei=村田 kn-aut-mei=隆 aut-affil-num=3 ORCID= en-aut-name=HimeiYusuke en-aut-sei=Himei en-aut-mei=Yusuke kn-aut-name=姫井裕助 kn-aut-sei=姫井 kn-aut-mei=裕助 aut-affil-num=4 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 en-keyword=Optical scattering kn-keyword=Optical scattering en-keyword=Glass-ceramics kn-keyword=Glass-ceramics en-keyword=Oxyfluoride glass kn-keyword=Oxyfluoride glass en-keyword=Microcrystallite kn-keyword=Microcrystallite en-keyword=Upconversion fluorescence kn-keyword=Upconversion fluorescence END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=53 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=1999 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ライムギ小型染色体を保持する普通系コムギからのライムギ型cDNAのディファレンシャルスクリーニング kn-title=Differential Screening of Rye-type cDNAs from a Common Wheat Carrying the Rye Midget Chromosomes en-subtitle= kn-subtitle= en-abstract=ライムギの細胞質を有する普通系コムギ(cereale)-Chinese Spring (CS)には、「ミジェット」と呼ばれる非常に小型の染色体が存在する。この染色体が失われると、その種子は胚乳が退化して発芽出来ない。かりに発芽しても、その植物は虚弱で不稔となる。このことは、この染色体にライムギ細胞質の機能維持に不可欠な遺伝子が座乗していることを示唆している。本研究では、ディファレンシャルスクリーニング法により、このミジェット染色体に座乗している遺伝子の同定を試みた。(cereale)-CSの若苗からcDNAライブラリーを作成し、約20,000のプラークをスクリーニングした。その結果、ライムギのcDNAには強くハイブリダイズするが、CSのcDNAには弱くハイブリダイズするクローンが27得られた。これらについてその特異性をサザンハイブリダイゼイション等で解析したところ、19個のクローン( CrClAなど) はサイズ、制限酵素部位に違いは認められるもののお互いにハイブリダイズすることから、同じクラスⅠに分類された。これらは、正常CSと(cereale)-CSとの間でRELP(制限酵素断片長多型)を示し、その型はライムギと同様であった。このcDNAの塩基配列は、コムギ葉緑体DNA遺伝子rbcLに類似しており、ライムギの葉緑体DNAに由来していると考えられた。他のクローンは、コムギの核遺伝子cabとrbcにその塩基配列が類似していたが、はっきりとした多型は検出されなかった。ここで用いた方法では、光合成に関連した発現量の多いcDNAがスクリーニングされやすい傾向があり、効率的なスクリーニングには均一化したcDNAを用いる必要があると思われる。 kn-abstract=Occurrence of the midget chromosome in a common wheat with rye cytoplasm [(cereale)-Chinese Spring (CS)] indicates that the chromosome carries the essential gene(s) for maintaining the function of rye cytoplasm. To elucidate the interaction between the midget chromosome and rye cytoplasm, in this study, an attempt was made to isolate rye-type cDNAs from a cDNA library of (cereale)-CS by differential screening. Two replica filters from each plate were hybridized with digoxigenin (DIG)-labeled wheat CS cDNAs and with DIG-labeled rye cDNAs,respectively. Out of ca. 20,000 plaques, 27 were hybridized more strongly with rye cDNAs than with CS cDNAs. These clones were classified into six classes (Ⅰ-Ⅵ) by blot hybridization. The majority of the clones (21 out of 27) was belonged to the same class (1), showing rye-type RFLP (restriction fragment length polymorphism). The DNA sequence of clone CrClA in class Ⅰ, was very similar to that of wheat ribulose 1,5-bisphosphate carboxylase,large subnit gene, rbcL(94.5% homology). However, the 3' end of CrClA was shorter than that of wheat rbcL, and terminated at TAA instead of TAG, like the rbcL of Aegilops crassa. In the clone CrC5.4, the first half of the sequence was similar to that of one rice EST clone, the functions of which are not known, and the latter was similar to the reverse sequence of maize 4.5S-23S ribosomal RNA. This suggests that CrC5.4 had been derived from two defferent cDNAs of (cereale)-CS. Three other clones had homology to the chlorophyll a/b binding protein genes (cab) of wheat, maize and tomato, and one to wheat rbcS (ribulose1,5-bisphosphate carboxylase small subnit gene). However, no clear polymorphisms were detected between wheat and rye by using those clones as probes. en-copyright= kn-copyright= en-aut-name=MurataMinoru en-aut-sei=Murata en-aut-mei=Minoru kn-aut-name=村田稔 kn-aut-sei=村田 kn-aut-mei=稔 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=Cytoplasm substitution line kn-keyword=Cytoplasm substitution line en-keyword=Differential screening kn-keyword=Differential screening en-keyword=Midget chromosome kn-keyword=Midget chromosome en-keyword=Rye kn-keyword=Rye en-keyword=Wheat kn-keyword=Wheat END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=49 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=幼苗期と成熟期のオオムギ系統間における禾穀類アブラムシの密度とグラミン含量の関係 kn-title=Relationship between Gramine Concentration and Cereal Aphid Polulations in Seedling and Maturation Stages in Barley Lines en-subtitle= kn-subtitle= en-abstract=オオムギ(Hordeum spontaneum及びH.vulgare)14系統の幼苗期と成熟期における、アブラムシの密度とインドールアルカロイド化合物であるグラミン含量の関係を調べた。温室内の幼苗では、グラミン含量に関わらずムギミドリアブラムシ(Schizaphis graminum)の寄生密度に有意差は認められなかった。一方、ムギクビレアブラムシ(Rhopalosiphum padi)の密度は、幼苗間で異なる場合もあった。圃場におけるアブラムシの寄生に対して、抵抗性は出穂期に顕著に現れた。アブラムシの寄生密度とグラミン含量の間には負の相関が認められた。成熟期のオオムギでは、グラミンの分解活性の高い感受性系統と比較して、抵抗性系統のグラミン含量は多く、特に野生系統では著しかった。 kn-abstract=The relationship between the indole alkaloid gramine concentration and aphid population was examined seedling and maturation stages in 14 barley lines of Hordeum spontaneum and H. unlgare. The density of Schizaphis graminum did not differ significantly with the gramine concentration in the seedling in the greenhouse. However, the population of Rhopalosiphum padi sometimes differed with the seedling. The plant resistance to the natural infestation of cereal aphids was obvious at the heading stage. There was a negative correlation between the high population density of aphids and gramine concentration. The gramine concentration was high in matured resistant resistant lines, especially wild lines, as compared with susceptible lines due to higher biodegradation activity. en-copyright= kn-copyright= en-aut-name=MoharramipourSaeid en-aut-sei=Moharramipour en-aut-mei=Saeid kn-aut-name=MoharramipourSaeid kn-aut-sei=Moharramipour kn-aut-mei=Saeid aut-affil-num=1 ORCID= en-aut-name=MurataShin-ichi en-aut-sei=Murata en-aut-mei=Shin-ichi kn-aut-name=村田眞一 kn-aut-sei=村田 kn-aut-mei=眞一 aut-affil-num=2 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=3 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Resistance kn-keyword=Resistance en-keyword=Gramine kn-keyword=Gramine en-keyword=Cereal aphids kn-keyword=Cereal aphids END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=1 article-no= start-page=73 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19950201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Role of Plasma Membrane K+ Channels in Salt Adaptation of Tabacco Suspension Cells kn-title=タバコ培養細胞の塩ストレス適応機構における原形質膜カリウムチャンネルの役割 en-subtitle= kn-subtitle= en-abstract=一般に、高等植物は塩に弱く、土壌の塩の集積によって、生育が困難になり、枯死に至る。しかし、塩に強い、あるいは、塩を好む高等植物も存在している。これらの植物の耐塩性あるいは塩ストレス適応機構の解明は、塩ストレス適応植物または耐塩性植物作出のための基礎的知見を与える。高等植物にとって塩ストレスは、ナトリウムによる代謝阻害を意味する。《イオンストレス》と、水分の吸収に関わる《浸透圧ストレス》とに大別される。これまでの研究によって、塩ストレスの主たる原因は、《イオンストレス》であることが知られるようになった。また、塩生植物も含め高等植物は塩に強い酵素を持たないため、細胞質中の高いカリウムイオンとナトリウムイオンとの比(K+/Na+)の維持が塩ストレス適応機構および耐塩性機構にふかく関わっていることも明らかにされつつある。しかし、細胞質中の高K+やNa+の主な流出入の経路と考えられる原形質膜のイオンチャンネルの役割については、ほどんど明らかにされていない。また、塩ストレスの初期の段階でNa+によって原形質膜表面のCa2+が置換されることや細胞外のCa2+の減少によってK+の流出が起きること、細胞外のCa2+によって塩ストレスが軽減されることなど、Ca2+が塩ストレスの初期の段階で重要な動きをしていることが示唆されている。しかし、そのCa2+の制御機構についても、詳細は明らかにされていない。本研究では、高等植物の細胞レベルでの研究に適しているタバコ培養細胞(BY-2)を材料として、また電気生理学的手法(パッチクランプ法、細胞電気泳動法、本研究で確立した蛍光プローブによる定量的膜電位測定法)を用いて、高等植物の塩ストレス適応機構における原形質膜のK+チャンネルの役割の解明、塩ストレス適応機構における細胞内外および表面のCa2+の役割の解明を行なった。 kn-abstract=The fluorescent probe method was applied to determine the membrane potential of tobacco (Nicotiana tabacum L. cv Bright Yellow) cells that were either unadapted (NaCl-unadapted cells) or adapted to 50 mM NaCl (Na50-adapted cells). There were no deffrences in the bahavior of the membrane potential between the NaCl-unadapted cells and the Na50-adapted cells. The patch-cpamp technique was used to study and compare the characterristics of cation channels in the plasma membrance of NaCl-unadapted cells, Na50-adapted and Na100-adapted cells. The steady-state amplitude of the outward whole-cell currents decreased in the following order; NaCl-unadapted cells>Na50-adapted cells>Na100-adapted cells. There were no significant differences between the NaCl-unadapted cells and the Na50-adapted cells in terms of the K+/Na+ selectivity of these channels. These observations suggest that adaptation to salinity in reduced permeability of the K+ channels to both K+ and Na+. K+ channels in the plasma membrane were investigated using the patch-clamp technique. The outward rectifying whole-cell currents were reduced with increasing extracellular Ca2+ and were independent of intracellular Ca2+. The K+/Na+ selectivity were independent of Ca2+ concentration. These observations suggest that extracellular Ca2+ is an important factor in the regulation of ion permeability. The characteristics of Ca2+ binding on the plasma membrane were investigated by the micro-electrophoresis tecniqui. Comparison of the amount of Ca2+ bound in the presence of 30 mM NaCl with that in the presence of 30 mM KCl indicated that Na+ reduced the amount of Ca2+ bound to the plasma membrane of the NaCl-unadapted cells,but did not reduce the amount of Ca2+ bound to the plasma membrane of the Na50-adapted cells.

For the plasma membrane, difference spectra measured after irradiation of near-UV suggested the decomposition of ergosterol and the suggestion was proved by HPLC analysis. Experiments in model systems revealed that ergosterol itself was the photoreceptor in the photochemical reaction, and that there was not any other photoreceptor or photosensitizer which was related to photochemical reaction of ergosterol decomposition in the plasma membrane. en-copyright= kn-copyright= en-aut-name=NakaumaMakoto en-aut-sei=Nakauma en-aut-mei=Makoto kn-aut-name=中馬誠 kn-aut-sei=中馬 kn-aut-mei=誠 aut-affil-num=1 ORCID= en-aut-name=AramiShin-ichiro en-aut-sei=Arami en-aut-mei=Shin-ichiro kn-aut-name=荒見真一郎 kn-aut-sei=荒見 kn-aut-mei=真一郎 aut-affil-num=2 ORCID= en-aut-name=HadaMegumi en-aut-sei=Hada en-aut-mei=Megumi kn-aut-name=秦恵 kn-aut-sei=秦 kn-aut-mei=恵 aut-affil-num=3 ORCID= en-aut-name=NakagawaIchiro en-aut-sei=Nakagawa en-aut-mei=Ichiro kn-aut-name=中川一郎 kn-aut-sei=中川 kn-aut-mei=一郎 aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name=村田芳行 kn-aut-sei=村田 kn-aut-mei=芳行 aut-affil-num=5 ORCID= en-aut-name=TadaMikiro en-aut-sei=Tada en-aut-mei=Mikiro kn-aut-name=多田幹郎 kn-aut-sei=多田 kn-aut-mei=幹郎 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=農林水産省食品総合研究所 affil-num=3 en-affil= kn-affil=神戸大学理学部 affil-num=4 en-affil= kn-affil=九州農政局 affil-num=5 en-affil= kn-affil=岡山大学 affil-num=6 en-affil= kn-affil=岡山大学 en-keyword=Rhodotorula minuta kn-keyword=Rhodotorula minuta en-keyword=near-UV kn-keyword=near-UV en-keyword=ergosterol kn-keyword=ergosterol en-keyword=absorbance change kn-keyword=absorbance change END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=1 article-no= start-page=45 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=200002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Photochemical Products from Ergosterol in the Plasma Membrane of the Yeast Rhodotorula minuta cells illuminated by Near-UV kn-title=長波長紫外光によって酵母 Rhodotorula minuta 細胞膜に生じるエルゴステロールの光化学反応生成物 en-subtitle= kn-subtitle= en-abstract=赤色酵母R.minuta細胞膜に長波長紫外光を照射した時に生じるエルゴステロール由来の光化学反応生成物の単離・精製およびその同定を行った。結果、3種類の物質が単離・精製され、そのうち1つはPrevitamin D2であることが同定され、残りの2つについてはergosta-4,7,22-trien-3-on の何かの炭素にOH基が付いたものであることが分かった。単離した成分を培地に加え、菌体の増殖とカロテノイド生合成に対する影響を調べた結果、これらの物質はそのどちらにも影響を及ぼさなかった。 kn-abstract=When the plasma mumbrane of the yeast Rhodotorula minuta cells was exposed to near-UV at 0℃, three new compounds were formes photochemically with decrease in ergosterol content.

In addition, these photochemical products did not affect the growth and carotenogenesis of the yeast Rhodotorulaminuta. en-copyright= kn-copyright= en-aut-name=NakaumaMakoto en-aut-sei=Nakauma en-aut-mei=Makoto kn-aut-name=中馬誠 kn-aut-sei=中馬 kn-aut-mei=誠 aut-affil-num=1 ORCID= en-aut-name=IriyamaTakuya en-aut-sei=Iriyama en-aut-mei=Takuya kn-aut-name=入山卓也 kn-aut-sei=入山 kn-aut-mei=卓也 aut-affil-num=2 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name=村田芳行 kn-aut-sei=村田 kn-aut-mei=芳行 aut-affil-num=3 ORCID= en-aut-name=TadaMikiro en-aut-sei=Tada en-aut-mei=Mikiro kn-aut-name=多田幹郎 kn-aut-sei=多田 kn-aut-mei=幹郎 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Rhodotorula minuta kn-keyword=Rhodotorula minuta en-keyword=near-UV kn-keyword=near-UV en-keyword=ergosterol kn-keyword=ergosterol en-keyword=photochemical products kn-keyword=photochemical products 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=2000 dt-pub=20000325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ウシグソヒトヨタケにおける性形態形成の遺伝学的及び分子生物学的解析 kn-title=Genetic and Molecular Analyses of Sexual Morphogenesis in Coprinus cinereus en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=村田幸男 kn-aut-sei=村田 kn-aut-mei=幸男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 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=1970 dt-pub=19700930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ヒトの骨格筋線維分化に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=村田文雄 kn-aut-sei=村田 kn-aut-mei=文雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 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=1997 dt-pub=19970325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=拡張型心筋症におけるI-MIBGシンチグラフィーと心内膜下心筋生検組織所見の対比検討 kn-title=Relation of Iodine-1'23 Metaiodobenzy lguanidine Myocardial Scintigraphy to Endomyocardial Biopsy Findings in Patients with Dilated Cardiomyopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=村田克敏 kn-aut-sei=村田 kn-aut-mei=克敏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 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=1967 dt-pub=19670930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=制癌剤の副作用防止に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=村田雅彦 kn-aut-sei=村田 kn-aut-mei=雅彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END
