Exosomal Galectin-3 promotes peritoneal metastases in gastric adenocarcinoma via microenvironment alterations.

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear.

Risk-Based Screening of Atrial Fibrillation in General Practice (R-BEAT): A randomised Cross-over Trial.

Background: The optimal approach to the diagnosis of atrial fibrillation in primary care is unclear.

Aim: To determine if external loop recorder (ELR) screening improves atrial fibrillation detection in community dwelling adults with a CHA2DS2-VASc score of greater than two.

Design: Randomised cross-over clinical trial.

Social and nonsocial environmental loss have differential effects on ventral hippocampus-dependent behavior and inhibitory synaptic markers in adult male mice.

In humans, psychological loss, whether social or nonsocial, can lead to clinical depression, anxiety disorders, and social memory impairments. Researchers have modeled combined social and nonsocial loss in rodents by transitioning them from social, enriched environments (EE) to individual housing, affecting behaviors related to avoidance, stress coping, and cognitive function. However, it remains unclear if these effects are driven by social or nonsocial loss.

Clinical disease in British sheep infected with an emerging strain of bluetongue virus serotype 3.

Background: Bluetongue virus serotype 3 (BTV-3) was detected for the first time in cattle and sheep in southern England in 2023, the first UK BTV incursion for more than 15 years. Clinical signs were not observed, yet severe clinical disease and mortality were reported during recent BTV-3 outbreaks in northern Europe.

Methods: To investigate the clinical disease and infection kinetics associated with this UK BTV-3 strain, five British sheep were infected with a UK BTV-3 isolate using Culicoides biting midges.
