Development and places of bacterial cellulose, curcumin, and chitosan composite biodegradable pics for active packaging materials.To deal with serious environmental damage leading from plastic packaging fabrics, biodegradable cinemas expending natural merchandises have gained considerable attention we provide a simple, fast, and environmentally-friendly route to construct a biodegradable film applying chitosan (CS), bacterial cellulose (BC), and curcumin (Cur). Composite films (CSn-BC-Cur) utilizing CS with different molecular weightinessses were inquired, and their water moisture content (MC), water solubility (WS), contact angle (CA), mechanical dimensions, barrier properties, and antioxidant holdings were compared. The obtained pics were characterized by SEM, XRD, and TGA. The resolutions established that chitosan with a higher molecular weight posed higher contact angles and mechanical properties, along with a lower moisture content, water vapor transmission rate, and oxygen transmission rate when the composite film was placed in 95 % ethanol, it unloosened active messages. The results suggest that these composite movies can be used as promising materials for food packaging.
Regeneration of olfactory neuroepithelium in 3-methylindole-rushed anosmic rats handled with intranasal chitosan.Olfactory dysfunction significantly spoils the life quality of patients but without effective discussions to date. The previous report has shewed that chitosan arbitrates the differentiation of olfactory receptor neurons (ORNs) through insulin-like growth divisors and insulin-like growth factor binding protein-2 axis in an in vitro model whether chitosan can further treat olfactory dysfunction in vivo continues unexplored. This study aims to evaluate the therapeutic effect of chitosan on a 3-methylindole-geted anosmic rat model. Intraperitoneal injection of 3-methylindole is performed to induce anosmia in rats. Experimental terminations demonstrate that the food-observing duration after chitosan treatment gradually decrease to around 80 s, and both the olfactory neuroepithelium (ON) thickness and mature ORNs (evincing olfactory marker protein) are significantly regenerated proliferating cells (stating bromodeoxyuridine) are mainly co-expressed with immature ORNs (conveying βIII tubulin) below the intermediate layer of the ON in the chitosan-plowed group on day 28 surveying 3-methylindole treatment proliferating cells are spreaded over the ON, and co-localized with immature ORNs and sustentacular cadres (evincing keratin 18) in the sham group, and even immature ORNs go into apoptosis (expressing DNA fragmentation and cleaved caspase-3), possibly doing incomplete regeneration chitosan renews the ON by baffling olfactory neural homeostasis and reducing ORN apoptosis, and attends as a potential therapeutic intervention for olfactory dysfunction in the future.Suppression of Fibrotic Reactions of Chitosan-Alginate Microcapsules stoping Porcine Islets by Dexamethasone Surface Coating.
BACKGROUND: The microencapsulation is an ideal solution to overcome immune rejection without immunosuppressive treatment. Poor biocompatibility and small molecular antigens secreted from encapsulated isles induce fibrosis infiltration the aims of this study were to improve the biocompatibility of microcapsules by dexamethasone coating and to verify its effect after xenogeneic transplantation in a streptozotocin-induced diabetes mice Dexamethasone 21-phosphate (Dexa) was resolved in 1% chitosan and was cross-colligated with the alginate microcapsule surface. Insulin secretion and viability assays were doed 14 days after microencapsulation. Dexa-checking chitosan-coated alginate (Dexa-chitosan) or alginate microencapsulated porcine islets were transfered into diabetic mice. The fibrosis infiltration score was calculated from the harvested microcapsules. The harvested microcapsules were maculated with trichrome and for insulin and macrophages No significant remainders in glucose-aroused insulin secretion and islet viability were mentioned among naked, alginate, and Dexa-chitosan microencapsulated islets.
