| Abstract | Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars. |

| Abstract | We evaluated how exposure to airborne volatile organic compounds emitted from a plastic recycling facility affected nearby residents, in a cross-sectional study. Individuals>10 years old were randomly sampled from 50 households at five sites and given questionnaires to complete. We categorized the subjects by distance from the recycling facility and used this as a proxy measure for pollutant exposure. We sought to improve on a preceding study by generating new findings, improving methods for questionnaire distribution and collection, and refining site selection. We calculated the odds of residents living 500 or 900 m away from the facility reporting mucocutaneous and respiratory symptoms using a reference group of residents 2,800 m away. Self-reported nasal congestion (odds ratio=3.0, 95% confidence interval=1.02-8.8), eczema (5.1, 1.1-22.9), and sore throat (3.9, 1.1-14.1) were significantly higher among residents 500 m from the facility. Those 900 m away were also considerably more likely to report experiencing eczema (4.6, 1.4-14.9). Air pollution was found responsible for significantly increased reports of mucocutaneous and respiratory symptoms among nearby residents. Our findings confirm the effects of pollutants emitted from recycling facilities on residents’ health and clarify that study design differences did not affect the results. |

| Abstract | Vascular dysfunction has been reported in women with recurrent pregnancy loss (RPL). We investigated the severity of vascular dysfunction in non-pregnant women with RPL and its correlation with anti-heat shock protein (HSP) antibodies that are known to induce arteriosclerosis. We measured the serum anti-HSP60 antibodies, anti-HSP70 antibodies, and anti-phospholipid antibodies (APA) in 68 women with RPL and 29 healthy controls. Among the women with RPL, 14 had a diagnosis of antiphospholipid syndrome (APS), and in the remaining 54, the causes for RPL were unexplained. Compared to the controls, the brachial-ankle pulse wave velocity (baPWV), carotid augmentation index (cAI), and uterine artery pulsatility index (PI) were all significantly higher in the women with both APS and unexplained RPL. Compared to the controls, the anti-HSP60 antibody levels were significantly higher in the APA-positive group of women with unexplained RPL, and the anti-HSP70 antibody levels were significantly higher in APS and APA-positive group of women with unexplained RPL. However, the anti-HSP60 and anti-HSP70 antibody levels did not correlate with the values of baPWV or cAI. Our results demonstrated anti-HSP60 and anti-HSP70 antibodies are increased in women with unexplained RPL. Further studies are needed to elucidate the roles of anti-HSP antibodies and their pathophysiology in unexplained RPL. |

| Abstract | Electroencephalogram (EEG) data include broadband electrical brain activity ranging from infra-slow bands (< 0.1 Hz) to traditional frequency bands (e.g., the approx. 10 Hz alpha rhythm) to high-frequency bands of up to 500 Hz. High-frequency oscillations (HFOs) including ripple and fast ripple oscillations (80-200 Hz and>200 / 250 Hz, respectively) are particularly of note due to their very close relationship to epileptogenicity, with the possibility that they could function as a surrogate biomarker of epileptogenicity. In contrast, physiological high-frequency activity plays an important role in higher brain functions, and the differentiation between pathological / epileptic and physiological HFOs is a critical issue, especially in epilepsy surgery. HFOs were initially recorded with intracranial electrodes in patients with intractable epilepsy as part of a long-term invasive seizure monitoring study. However, fast oscillations (FOs) in the ripple and gamma bands (40-80 Hz) are now noninvasively detected by scalp EEG and magnetoencephalography, and thus the scope of studies on HFOs /FOs is rapidly expanding. |

| Abstract | Adenohypophysis delivered from oral ectoderm consists of pars distalis (PD), pars intermedia and pars tuberalis (PT). The mechanisms of development of PD has been well studied, and the cell differentiation of PD has been well understood. However, the morphogenesis and the differentiation of PT are still unclear, and the gene expression during the PT development remains largely unknown. In this study, we explored the specifically expressing genes in PT during development and analyzed its spatiotemporal expressions pattern. Microarray analysis on laser-captured PT and PD tissues obtained from chicken embryos on embryonic day 10 (E10.0) showed high expressing genes, Cytokine-like 1 (CYTL1) and Gap junction protein alpha 5 (GJA5) in PT. A detail analysis of spatiotemporal expressions pattern during chick embryo development by in situ hybridization revealed that CYTL1 mRNA was first detected in lateral head ectoderm and ventral head ectoderm in E1.5. The CYTL1 expressions moved into Rathke’s pouch at E2.5, then it was localized in PT primordium and continuously expressed in PT primordium until E12.0. On the other hand, GJA5 mRNA was transiently detected in PT primordium from E6 to E14.0, while the expression was not detected in PD during development. These results suggested that these genes may be involved in the regulation mechanism of PT development and could be a useful marker in the PT development. |

| Abstract | Spiny mice are useful in regenerative research and as a model for precocial animals. In the present study, we investigated the taxonomic status of the Aco strain, which is derived from spiny mice of an unidentified species. Although this Aco strain has been tentatively considered A. cahirinus species, it was distinguished from this species based on conventional and G-banding chromosomal patterns of this strain. Subsequently, we determined the nucleotide sequence of the mitochondorial gene cytochrome b (Cyb) and constructed a molecular phylogenetic tree. We found that the Aco strain belongs to the same clade as A. dimidiatus. Based on this molecular analysis, we concluded that the Aco strain of spiny mice should be considered A. dimidiatus. |

| Title Alternative | Dissecting the hierarchy and lineage of mesenchymal stem cells by mouse genetics |

| Abstract | Determination of stem cell hierarchy/lineage is indispensable for a better understanding and augmentation of many aspects of medical sciences, including the mechanisms of tissue development and maintenance of tissue homeostasis, as well as disease development. It also has implications in the field of tissue regeneration for medical treatments and disease modeling for drug discovery using iPS technology. Mesenchymal stem cells are multipotent stem cell that can differentiate into various type of cells including osteoblasts, adipocytes, myocytes and chondrocytes. Runt-related transcription factor 2 (Runx2) is an essential transcriptional regulator of osteoblast differentiation. Runx2 deficiency in Prx1+-derived cells (Runx2prx1−/− mice) resulted in defective intramembranous ossification. Double-positive cells for Prx1-GFP and stem cell antigen-1 (Sca1) (Prx1+Sca1+ cells) in the calvaria expressed Runx2 at lower levels and were more homogeneous and primitive as compared with Prx1+Sca1− cells. Our results suggest that osteoblast differentiation in vivo may begin at the Prx1+Sca1+ MSC stage with sequential progression to Prx1+Sca1−cells, then Osx+Prx1−Sca1− osteoblast precursors, which eventually form mature α1(I)-collagen+ osteoblasts. |

| Title Alternative | Overview and future perspectives of studies on the mechanisms underlying appetite regulation in chickens |
|---|---|
| FullText URL | poalas_033_008_010.pdf |
| Author | Honda, Kazuhisa| |
| Abstract | Broiler chickens eat more feed than layer chickens. As a result, broiler chickens grow faster than layer chickens. However, excessive accumulation of body fat in broiler chickens has been a serious problem in the poultry industry in recent decades. Therefore, the appetite regulatory system of chickens has been a focus of research among poultry scientists. Lines of evidence suggest that the physiological role of peripheral adiposity hormones, such as leptin and insulin, and gut hormones, such as ghrelin, are different between mammals and chickens. Thus, species specificity make it difficult to understand the mechanisms underlying the regulation of food intake in chickens. Here I provide an overview of recent findings in this field and future perspectives. |

| Title Alternative | Pharmacokinetic analysis of drug absorption following nasal application to rats |

| Author | 古林 呂之| |
| Abstract | Since a drug applied to the nose in an in vivo physiologic condition is translocated to the gastrointestinal (GI) tract by mucociliary clearance (MC), the drug undergoes absorption both from the nasal cavity and from the GI tract. The detailed MC of the rat was examined, using inulin as a marker of the applied solution. Inulin disappeared monoexponentially from the nasal cavity, indicating that the MC can be assumed to follow first-order kinetics. In the proposed kinetic model, the fractional absorption of the drug following nasal application is predicted as the sum of fractional absorption from the nasal cavity and fractional absorption from the GI tract, both of which are estimated indirectly from the permeability to the Caco-2 monolayer. This kinetic model is the first estimation system for nasal drug absorption based on drug disposition after nasal application and is useful for the development of nasal dosage forms. |
