Synaptic Targets and Cellular Sources of CB1 Cannabinoid Receptor and Vesicular Glutamate Transporter-3 Expressing Nerve Terminals in Relation to GABAergic Neurons in the Human Cerebral Cortex.

Cannabinoid receptor 1 (CB1) regulates synaptic transmission through presynaptic receptors in nerve terminals, and its physiological roles are of clinical relevance. The cellular sources and synaptic targets of CB1-expressing terminals in the human cerebral cortex are undefined. We demonstrate a variable laminar pattern of CB1-immunoreactive axons and electron microscopically show that CB1-positive GABAergic terminals make type-2 synapses innervating dendritic shafts (69%), dendritic spines (20%) and somata (11%) in neocortical layers 2-3.

AQUABEAM robotic system use-results survey: Aquablation for the treatment of lower urinary tract symptoms due to benign prostatic hyperplasia in the Japanese Population.

Objectives: To evaluate the safety, efficacy, and patient-reported outcomes of Aquablation therapy using the AQUABEAM Robotic System for the treatment of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) in a Japanese population.

Methods: This post-market use-results survey included 103 Japanese men with BPH who underwent Aquablation across five centers with previously Aquablation naïve physicians. Data were collected at baseline, during the procedure, at discharge, and at 3 and 6 months post-procedure.

Retromode Infrared Scanning Laser Ophthalmoscopy in Vogt-Koyanagi-Harada Disease.

Purpose: This study examined six patients with Vogt-Koyanagi-Harada (VKH) disease using retromode infrared scanning laser ophthalmoscopy (RMI-SLO).

Methods: We conducted a single-center retrospective review of the medical records of six patients diagnosed with VKH disease. The RMI-SLO images were compared to those obtained using color fundus photography, optical coherence tomography (OCT), and dye-based retinal angiography.

Effects of Fasting on Metabolic Hormones and Functions: A Narrative Review.

The occurrence of the metabolic syndrome and its related diseases such as diabetes are steadily rising in our modern society. Modern food choices and the more sedentary lifestyles largely contribute to this shift in our society's health. Fasting has been practiced for religious purposes all over the world long time before science showed the benefits of it.

Advantages of online supercritical fluid extraction and chromatography hyphenated to mass spectrometry to analyse plastic additives in laboratory gloves.

Plastic additives are introduced in plastic material formulations, along with organic polymers, to offer different properties such as stability, plasticity or color. However, plastic additives may migrate from the plastic material to the content (in case of plastic containers) or to the material in contact with the plastic, like human skin. In the case of plastic medical devices, this migration is of particular interest, as plastic additives may be deleterious to health.

Pre-Op Hydronephrosis Predicts Outcomes in Patients Receiving Robot-Assisted Radical Cystectomy.

Introduction: Robot-assisted radical cystectomy (RARC) has gained momentum in the management of muscle invasive bladder cancer (MIBC). Predictors of RARC outcomes are not thoroughly studied. We aim to investigate the implications of preoperative hydronephrosis on oncological outcomes.

Blue Wavelength of Scanning Laser Ophthalmoscope Potentially Detects Arteriosclerotic Lesions in Diabetic Retinopathy.

(1) Background: The fundus examination is one of the best and popular methods in the assessment of vascular status in the human body. Direct viewing of retinal vessels by ophthalmoscopy has been utilized in judging hypertensive change or arteriosclerosis. Recently, fundus imaging with the non-mydriatic scanning laser ophthalmoscope (SLO) has been widely used in ophthalmological clinics since it has multimodal functions for optical coherence tomography or angiography with contrast agent dye.

Androgen Receptor Splice Variant 7 in Asian Patients With Metastatic Castration-Resistant Prostate Cancer.

Purpose: Androgen receptor splice variant 7 (ARV-7) is a resistance mechanism to hormonal therapy in metastatic castrate-resistant prostate cancer (mCRPC). It has been associated with poor outcomes. On progression to castrate resistance, ARV-7 positivity has been identified in global populations at an incidence of 17.

Association Between Menopausal Symptoms and Work-Related Factors Among Female Workers in Japan: A Cross-Sectional Study.

Objective: Although menopausal symptoms are an important issue for female workers, their association with work-related factors is not well studied. Here, we explored the association between work-related factors and menopausal symptoms in Japan.

Methods: A cross-sectional study was conducted in 2023 among all 1465 female employees of a large Japanese company.

Increased circulating polymorphonuclear myeloid-derived suppressor cells are associated with prognosis of metastatic castration-resistant prostate cancer.

Introduction: Myeloid-derived suppressor cell (MDSC) exhibits immunosuppressive functions and affects cancer progression, but its relationship with prostate cancer remains unclear. We elucidated the association of polymorphonuclear MDSC (PMN-MDSC) and monocytic MDSC (M-MDSC) levels of the total peripheral blood mononuclear cells (PBMCs) with prostate cancer progression and evaluated their roles as prognostic indicators.

Methods: We enrolled 115 patients with non-metastatic hormone-sensitive prostate cancer (nmHSPC, n = 62), metastatic hormone-sensitive prostate cancer (mHSPC, n = 23), and metastatic castration-resistant prostate cancer (mCRPC, n = 30).

A comparison of periodic health examinations and workplace health screening for workers in Singapore and Japan.

This article aims to provide a historical overview of how workplace safety and health legislations in Singapore and Japan have evolved, and perform a comparative analysis of the occupational health systems where work-related medical examinations and health screening are concerned. The discourse is centered on three key themes - coverage, comprehensiveness, and continuity of care. The comparative analysis was performed based on secondary data obtained from open-source platforms.

Association of genetically determined chronotype with circulating testosterone: a Mendelian randomization study.

Low testosterone levels in men have been linked to decreased physical and mental function, as well as a reduced quality of life. Previous prospective observational studies have suggested an association between testosterone and sleep traits, but the causality of this relationship remains unclear. We aimed to explore the potential causal link between genetically determined sleep traits and testosterone levels in men using Mendelian randomization (MR) analysis from the UK Biobank dataset.

Protocol for the nationwide registry of patients with polycystic kidney disease: japanese national registry of PKD (JRP).

Background: Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are major genetic polycystic kidney diseases that can progress to end-stage kidney disease (ESKD). Longitudinal data on the clinical characteristics associated with clinical outcomes in polycystic kidney disease (PKD), including the development of ESKD and cardiovascular disease (CVD) are lacking in Japan. To address this unmet need the authors are establishing a novel, web-based, Nationwide Cohort Registry Study-the Japanese Registry of PKD (JRP).

Evaluating Leukocyte Telomere Length and Myeloid-Derived Suppressor Cells as Biomarkers for Prostate Cancer.

Background: Leukocyte telomere length (LTL) and myeloid-derived suppressor cells (MDSC) are associated with aging and the development and progression of cancer. However, the exact nature of this relationship remains unclear. Our study aimed to investigate the potential of LTL and MDSC as diagnostic biomarkers for prostate cancer while also seeking to deepen our understanding of the relationship of these potential biomarkers to each other.
