Mitochondria‐associated membranes (MAMs): molecular organization, cellular functions, and their role in health and disease

FEBS Open Bio, EarlyView.
Mitochondria‐associated membranes (MAMs) are contact sites between the endoplasmic reticulum and mitochondria that regulate calcium signaling, lipid metabolism, autophagy, and stress responses. This review outlines their molecular organization, roles in cellular homeostasis, and how dysfunction drives neurodegeneration, metabolic disease, cancer, and ...

Bio‐Responsive Hydrogel for Targeted on‐Demand Release of a Phage Cocktail for Treatment of Pseudomonas aeruginosa Infection

Advanced Functional Materials, EarlyView.
This study presents an injectable hydrogel that responds to Pseudomonas aeruginosa infection by releasing a dual‐phage cocktail on demand. The system degrades selectively in infected wounds, enhances phage localization and stability, and shows potent antibiofilm activity and biocompatibility in an ex vivo human skin model—offering a promising strategy ...

Probiotics and safety [PDF]

The American Journal of Clinical Nutrition, 2001
Bacterial species that have traditionally been regarded as safe are used in probiotics; the main strains used include lactic acid bacteria and bifidobacteria that inhabit the intestinal tracts of humans and animals. However, reports of frequent isolation of bacteria used in probiotics from infection sources in recent years have raised much debate over ...
