Possible involvement of microglial P2RY12 and peripheral IL-10 in postpartum depression.

Postpartum depression (PPD) is another type of depression, including emotional fluctuation, fatigue, and anxiety. Based on the specific event like giving birth, it can be speculated that PPD might have its specific mechanism. Here, we confirmed that dexamethasone (DEX) administration during pregnancy (gestational days 16-18) induced depressive- and anxiety-like behaviors in dam (DEX-dam) after weaning period (3 weeks).

CCL20 inhibition for treating inflammation in ankylosing spondylitis.

Objectives: Th17 cells are known to play a significant role in AS. C-C motif chemokine ligand 20 (CCL20) binds to C-C chemokine receptor 6 (CCR6) on Th17 cells, promoting their migration to inflammation sites. The aim of this research is to examine the effectiveness of CCL20 inhibition in treating inflammation in AS.

Analysis of Single-Cell Transcriptome and Surface Protein Expression in Ankylosing Spondylitis Identifies OX40-Positive and Glucocorticoid-Induced Tumor Necrosis Factor Receptor-Positive Pathogenic Th17 Cells.

Objective: To demonstrate the immune landscape of blood and synovial cells in the setting of ankylosing spondylitis (AS) through the analysis of both single-cell transcriptome and surface protein expression, and to unveil the molecular characteristics of pathogenic Th17 cells.

Methods: This study included 40 individuals with active AS, 20 individuals with stable AS, 40 patients with active rheumatoid arthritis, and 20 healthy controls. Surface phenotype and intracellular staining were assessed using flow cytometry after peripheral blood mononuclear cells and synovial fluid mononuclear cells were stimulated with T cell receptor.

A molecular characterization and clinical relevance of microglia-like cells derived from patients with panic disorder.

Few studies report the microglia involvement in the pathogenesis of panic disorder (PD), although the crucial role of microglia in other neuropsychiatric diseases is being emphasized. In addition, there is no report to characterize the phenotypic and functional levels of PD patient-derived microglia to find their clinical relevance. Herein, we used a model to induce patient-derived microglia-like cells (iMGs) to clarify the molecular characteristics and function of PD-iMGs.

Comparisons of Fit Factors Between Two Quantitative Fit Testers (PortaCount vs. MT).

This study evaluated the consistency between two quantitative fit test devices with different methods of ambient aerosol counting. Three types of respirators (N95, half mask, and full facepiece) were worn by 50 participants (male, n = 25; female, n = 25), PortaCount (Pro+ 8038) and MT (05U) were connected to one probe to one mask, and fit factors (FFs) were measured simultaneously with the original and modified protocols. As a result of comparing MT FFs with PortaCount FFs as references and by applying for the pass/fail criteria (FF = 100), the consistency between the two devices for half masks and full facepieces was very high.

Microglia involvement in sex-dependent behaviors and schizophrenia occurrence in offspring with maternal dexamethasone exposure.

Fetal microglia that are particularly sensitive cells to the changes in utero environment might be involved in the sex-biased onset and vulnerability to psychiatric disorders. To address this issue, we administered a 50 µg/kg dexamethasone (DEX) to dams subcutaneously from gestational days 16 to 18 and a series of behavioral assessments were performed in the offspring. Prenatal exposure to dexamethasone (PN-DEX) induced schizophrenia (SCZ)-relevant behaviors in male mice and depressive-like behavior in female mice.

Fluoxetine Decreases Phagocytic Function via REV-ERBα in Microglia.

Although fluoxetine (FLX) is a commonly used drug in psychiatric disorders, such as major depressive disorder, anxiety disorder, panic disorder, and obsessive-compulsive disorder, the mechanism by which FLX exerts its therapeutic effect is not completely understood. In this study, we aimed to determine the possible mechanism by which FLX focuses on microglial phagocytosis. FLX reduced phagocytic function in BV2 cells and increased REV-ERBα without affecting other microglia-related genes, such as inflammation and phagocytosis.

Morbidity analysis of left hepatic trisectionectomy for hepatobiliary disease and live donor.

Background: Despite remarkable advances in surgical techniques and perioperative management, left hepatic trisectionectomy (LHT) remains a challenging procedure with a somewhat high postoperative morbidity rate compared with less-extensive resections. This study aimed to analyze the short- and long-term outcomes of LHT and identify factors associated with the postoperative morbidity of this technically demanding surgical procedure.

Methods: The medical records of 53 patients who underwent LHT between June 2005 and October 2019 at a single institution were retrospectively reviewed.

Persistent Acidic Environment Induces Impaired Phagocytosis via ERK in Microglia.

Acidic environment evoked by stroke, traumatic brain injury, and Alzheimer's disease may change the functional properties of microglia. Nevertheless, the underlying mechanisms of functional changes in microglia remain unclear. In this study, we found that acidic stimuli (pH 6.

Serum miR-3620-3p as a Novel Biomarker for Ankylosing Spondylitis.

Objective: Using microRNA (miR) as a biomarker has been a new way for diagnosing many diseases Although many studies on miR-biomarker have been published, researches on miR-biomarker in ankylosing spondylitis (AS) are limited Therefore, the objective of this study was to valiate a candidate serum miR as a novel disease-specific novel miR for AS.

Methods: Total RNAs were extracted from sera samples of patients with AS (n=57), patients with rheumatoid arthritis (RA) (n=37), or healthy controls (HC) (n=19) Through serum miR screening by microarray, differential levels of miR were subsequently validated by real time PCR At the time of serum sampling, clinical values such as sex, age, disease duration, AS-disease activity score, uveitis, peripheral arthritis, enthesitis, human leukocyte antigen-B27 presence, and recent medication were evaluated.

Results: We found that the expression level of serum miR-3620-3p in AS was notably lower than that in RA or HC The receiver-operator characteristics curve for determining the diagnostic accuracy showed an area under the curve of 0919 (p<0001) with a sensitivity of 871% and a specificity of 860% Correlation studies showed that the expression level of miR-3620-3p was only associated with the development of uveitis (p<005).

Persistence Enhancement of a Promising Tick Repellent, Benzyl Isothiocyanate, by Yeast Microcarriers.

Phenethyl isothiocyanate isolated from root oil and its derivatives were tested at different doses in a bioassay designed to evaluate repellency against individual nymphs. Among the tested compounds, benzyl isothiocyanate exhibited repellency against nymphs at the lowest dose of 0.00625 mg/cm, followed by phenethyl isothiocyanate (0.

Recovery of hesperidin and narirutin from waste peel using subcritical water extraction aided by pulsed electric field treatment.

The objective of this study was to identify whether the efficacy of extracting hesperidin and narirutin from peel by-products can be increased by combining pulsed electric field (PEF) and subcritical water extraction (SWE). The samples were treated with a PEF at a strength of 3 kV/cm for 60 and 120 s. Subsequent SWE was conducted at extraction temperatures of 110-190 °C for 3-15 min.

Manufacture of low-benzo(a)pyrene sesame seed (Sesamum indicum L.) oil using a self-designed apparatus.

The aim of this study was to lower benzo(a)pyrene (BaP) contents in sesame seed oil (SSO) during manufacture by using a self-designed apparatus, to determine its optimal conditions, and to analyze antioxidants in SSO which might be related to BaP content reduction. Washing and spin-drying steps reduce exogenous BaP contamination, and the reduced moisture in seeds lowered BaP content in final SSO. A ventilation system in the roasting step inhibits BaP formation and reabsorption, followed by a controlled compression step.
