Dietary polysaccharide-rich extract from Eucheuma cottonii modulates the inflammatory response and suppresses colonic injury on dextran sulfate sodium-induced colitis in mice.

Inflammatory bowel disease (IBD) is a known medical burden in most developed countries and a significant cause of morbidity. The IBD label includes Crohn's disease (CD) and ulcerative colitis (UC). Pharmacological and surgical intervention are the two main management approaches for IBD.

Amelioration effects of nanoencapsulated triterpenoids from petri dish-cultured on reproductive function of diabetic male rats.

Purpose: Nanoencapsulated triterpenoids from petri dish-cultured (PAC) and its amelioration effects on reproductive function in diabetic rats were investigated.

Materials And Methods: PAC encapsulated in silica-chitosan nanoparticles (Nano-PAC) was prepared by the biosilicification method. The diabetic condition in male Sprague Dawley rats was induced by high-fat diet and streptozotocin (STZ).

Interactions of acinar cells on biomaterials with various surface properties.

The purpose of this study is to evaluate the interactions of rat parotid acinar cells on biomaterials with different surface properties. The biomaterials used in this study included polyvinyl alcohol (PVA), chitosan, poly (ethylene-co-vinyl alcohol) (EVAL), and polyvinylidene fluoride (PVDF). Cell morphology was observed by photomicroscope.

Proliferation and phenotypic preservation of rat parotid acinar cells.

The purpose of this study is to develop an initial step in salivary gland tissue engineering through proliferation and phenotypic preservation of rat parotid acinar cells in vitro. By using the explant outgrowth technique and M199 medium with the addition of sialic acid, acinar cells not only survived for more than 30 days in the absence of basement membrane substrates but also proliferated to yield cells with acinar phenotypic expression. Furthermore, we tested whether chitosan can be used as a synthetic extracellular matrix to culture salivary acinar cells.
