Hyperexcitability of central amygdala (CeA) induces depressive symptoms. The bed nucleus of the stria terminalis (BNST) receives GABAergic input from the CeA. However, it remains unclear whether the GABAergic neurons in the CeA projecting to BNST contribute to major depression.

The SCA subtype SCA34 is caused by specific mutations in the gene , which encodes a fatty acid (FA) elongase that synthesizes ultra-long-chain (ULC; ≥C26) FAs. However, the pathogenesis and molecular mechanism that confers dominant inheritance remains unknown.

Two active X chromosomes are also observed in female embryonic stem cells (ESCs), but whether double doses of X-linked genes affect DNA repair efficiency remains unclear. Here, we establish isogenic female/male ESCs and show that the female ESCs are more sensitive to camptothecin and have lower gene targeting efficiency than male ESCs, suggesting that homologous recombination (HR) efficiency is reduced in female ESCs.

Cholestasis is a DILI that results from impairment of bile acid transporters, such as the bile salt export pump (BSEP), leading to accumulation of bile acids. Both in vitro and in vivo studies are required to predict the risk of drug-induced cholestasis.

Recently, some studies reported the expression of ERα on neoplastic cells from B-cell lymphomas. However, there has been only one report of ERα expression on the follicular dendritic cells (FDCs) that structurally and functionally support the microenvironment of follicular lymphomas (FLs).

This study aimed to analyze the clinicopathological data of BPDCN and evaluate immunohistochemical detection of minimal bone marrow (BM) involvement. In this study, we examined skin and BM lesions from 6 patients with BPDCN.

Chimeric mice with a humanized liver are expected to predict hepatotoxicity in humans. Drug-induced phospholipidosis (DIPL), in which phospholipids accumulate, is a known entity.

In the courses of our study to find antimutagens, we have found that.the ethanolic extract of the peel of Citrus unshiu Marc showed antimutagenic effects against several mutagens in the Ames test using Salmonella typhimurium TA98 strain.

The model was used to interpret the distributions of small plastic fragments and the possible transport processes in coastal waters. Of note, the size and quantity of mesoplastics (approximately >5mm) gradually increased close to the coast irrespective of the existence of river mouths, which probably act as a major source of anthropogenic marine debris.

Participants And Methods: We obtained medical records derived from 956,979 medical examinations carried out at JA Ehime Kouseiren Medical Examination Centers between April 1994 and March 2006. We analyzed data from 132,090 subjects (Toyo - 47,654, Chuyo - 38,435, Nanyo - 46,001) who underwent their first medical examination during this period.
Objective: The purpose of this study is to investigate factors influencing the osteo-sono assessment index (OSI) in junior high school students (boys, girls who had reached menarche, and girls who had not).
Methods: A total of 9,743 students (4,974 boys and 4,769 girls) in Ehime Prefecture participated in this study. We measured body mass index (BMI) and calcaneal bone mass using OSI.

Homocysteine plays a key role in several pathophysiological conditions. To assess the methionine-homocysteine kinetics by stable isotope methodology, we developed a simultaneous quantification method of [(2)H(7)]methionine, [(2)H(4)]methionine, methionine, [(2)H(4)]homocysteine and homocysteine in rat plasma by gas chromatography-mass spectrometry (GC-MS). [(13)C]Methionine and [(13)C]homocysteine were used as analytical internal standards to account for losses associated with the extraction, derivatization and chromatography.
