This work demonstrates successful gamma‐radiation‐induced grafting of N‐hydroxyethyl acrylamide onto poly[(R)‐3‐hydroxybutyrate], producing substantial changes in material properties. Grafting generated a biphasic, less crystalline structure with enhanced thermal stability, elongation (65%), toughness (378% increase), and exceptional water uptake (610 ...

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.

Mechanically adjustable and degradable scaffolds for the treatment of articular cartilage defects
Articular cartilage (AC) has long been known as the tissue that “once destroyed, is not repaired”. Damage to the AC may impair joint function, leading to osteoarthritis, joint destruction, and ultimately, joint replacement.

Packaging related properties of commercially available biopolymers – An overview of the status quo
Several commercially available thermoplastic biopolymers were processed in a continuous extrusion line. The molecular weight, crystallinity, and mechanical and permeation properties of the cast films were determined in order to evaluate the status quo of
