"Bamboo-like" strong and tough sodium alginate/polyacrylate hydrogel fiber with directional controlled release for wound healing promotion.

Skin, as the biggest organ and outermost surface of the human body, is prone to injury due to various challenges, especially the expanding potential of accidents, which bring a huge social and economic burden. Hydrogels are emerging as the most promising candidate for wound dressings, which not only fulfill the varied requirements of dressings but also serve as drug carriers. But limited breathability, rapid drug release, and inadequate mechanical properties remains a significant challenge.

Sporidiobolus pararoseus polysaccharides relieve rheumatoid arthritis by regulating arachidonic acid metabolism and bone remodeling signaling pathway.

Rheumatoid arthritis (RA) is an autoimmune-mediated disease with the highest disability rate. Sporidiobolus pararoseus polysaccharides (SPP) have been demonstrated to have anti-rheumatoid and microbiota-modulatory effects; however, the underlying mechanisms remain unclear. This study employed collagen-induced arthritis (CIA) mice to explore the metabolic and genetic pathways.
