Sarcopenia, a condition characterized by chronic systemic inflammation and a significant decline in the quality of life, is primarily associated with aging and degenerative diseases. Several studies have shown that milk exosomes contain a substantial number of miRNAs that are involved in immunity, inflammation, osteoporosis, and gut microbiota regulation. This study aimed to evaluate the potential functional role of bovine colostrum-derived exosomes (BCE) in reducing muscle atrophy.

Growing dementia prevalence underscores the need for efficient screening methods, but lengthy digital assessments often cause fatigue among older adults. To address this, we developed and validated the Digital Assessment of Cognitive Impairment (DACI), a brief mobile application designed to accurately identify cognitive impairment (CI). Initially, 304 older adults (272 healthy, 32 cognitively impaired) completed both a pencil-and-paper Cognitive Impairment Screening Test (CIST) and a full-length DACI.

Microplastics are pervasive pollutants in aquatic ecosystems, yet their effects on fish tissues remain insufficiently characterized. Our study investigates the impact of polystyrene microplastics (0.5 and 2 μm) on the gill and intestinal tissues of goldfish (), with a focus on inflammatory responses and pathogen susceptibility.

We tested if hyperoxic conditions can reduce the proportion of active myofibroblasts, which are assumed to be a major driver of head and neck radiation-induced fibrosis, as measured by expression levels of pro-fibrotic genes. Radiated, non-cancerous soft tissue from the head and neck and skin/soft tissue from non-radiated flap donor site were collected from each patient. Myofibroblast density was quantified using immunofluorescence staining with α-SMA and DAPI and visualisation under confocal microscopy and compared between baseline non-radiated and radiated tissue from the same patient.
