Chronic Jet Lag Disrupts Circadian Rhythms and Induces Hyperproliferation in Murine Lacrimal Glands via ROS Accumulation.

Purpose: Chronic jet lag (CJL) is known to disrupt circadian rhythms, which regulate various physiological processes, including ocular surface homeostasis. However, the specific effects of CJL on lacrimal gland function and the underlying cellular mechanisms remain poorly understood.

Methods: A CJL model was established using C57BL/6J mice.

Leptin Receptor Deficiency-Associated Diabetes Disrupts Lacrimal Gland Circadian Rhythms and Contributes to Dry Eye Syndrome.

Purpose: This study investigated the impact of hyperglycemia in type 2 diabetes mellitus (T2DM) on the circadian rhythms and function of lacrimal glands (LGs) in contributing to dry eye syndrome. We assessed the effects of hyperglycemia on circadian gene expression, immune cell recruitment, neural activity, and metabolic pathways, and evaluated the effectiveness of insulin in restoring normal LG function.

Methods: Using a T2DM mouse model (db/db mice), circadian transcriptomic changes in LGs were analyzed through RNA sequencing over a 24-hour period.

Temperature influence on matric suction in unsaturated soils: experimental insights.

Temperature is a critical factor affecting the matric suction of unsaturated soils. This study employed a simple and time-saving method to investigate the influences of temperature and moisture content on the temperature dependence of matric suction in loess and sand soils. Based on experimental data, the fitting performance of three data-fitting models-Brooks-Corey, van Genuchten, and Fredlund-Xing -was evaluated at temperatures above 0 °C.

Evaluating Senegal's COVID-19 surveillance system for early detection and response: lessons from the Keur Massar district, March 03, 2020 to May 31, 2022.

Background: The COVID-19 pandemic highlights the importance of strong surveillance systems in detecting and responding to public health threats. We sought to evaluate attributes of Keur Massar district's existing COVID-19 surveillance system.

Method: A descriptive, cross-sectional study was conducted in June 2022; desk review covered data collected from March 03, 2020 to May 31, 2022 in 18 health posts.

Valuing the importance of sex differences in prodromal Alzheimer's disease based on structural magnetic resonance imaging.

Background: Alzheimer's disease (AD) can be optimally managed from a healthcare point of view if detected at a prodromal stage. Amnestic mild cognitive impairment (MCI) is known as prodromal AD, has attracted extensive attention and research.

Objective: To identify the differences in cognitive function and structural magnetic resonance imaging (MRI) features between men and women with MCI on the basis of A/T/N classification system ("A" means amyloid-β biomarker, "T" means tau biomarker, and "N" means neurodegeneration biomarker as determined by clinical imaging (e.
