HKUMed reveals genetic evidence that diabetes drug GLP-1 receptor agonists achieve weight loss primarily by reducing fat mass more than muscle

Researchers found that GLP-1 receptor agonists decrease whole-body fat mass by about 7.9 kg for every unit reduction in BMI, while muscle mass decreases by 6.4 kg. This suggests that GLP-1 receptor agonists are more effective at reducing overall body fat than muscle mass.

Novel bifacial linker developed to prevent heterointerfacial delamination in flexible perovskite solar cells

A novel bifacial linker, potassium benzyl(trifluoro)borate (BnBF3K), has been developed to prevent heterointerfacial delamination in flexible perovskite solar cells. This study significantly enhances device performance and mechanical stability by optimizing adhesion at the SnO2/perovskite interface.

GPR107 deficiency linked to kidney damage in diabetes, potential for new therapies

Researchers identified GPR107 as a key regulator of COL4 levels in the kidney, finding that reduced GPR107 contributes to harmful COL4 accumulation and kidney damage. Strategies aimed at restoring or enhancing GPR107 function could represent a novel approach to preventing diabetic nephropathy progression.

Umbilical cord mesenchymal stem cells with reduced immune rejection and enhanced efficacy for intervention in severe acute pancreatitis

Researchers developed MSCs with aloe emodin-loaded nanoparticles and IFN-γ pretreatment, which inhibited CD4+T cell activation and reduced inflammation in mouse models. The combination also preserved pancreatic structure and function, holding promise for clinical application.
