Check Details  suggest H-C-M@Exo hydrogel is a promising biomaterial for the treatment of chronic diabetic wounds.Synthesis of Ganoderic Acids Loaded Zein-Chitosan Nanoparticles and Evaluation of Their Hepatoprotective Effect on Mice contributed Excessive Alcohol.Ganoderma lucidum, used in East Asia for its health welfares, stops ganoderic acids (GA) which have various pharmacological actions but are throttled by poor water solubility and low oral bioaccessibility. This study synthesized and qualifyed ganoderic Elvisses adulterated zein-chitosan nanoparticles (GA-NPs), and investigated its rewards in palliating alcoholic liver injury (ALI) in mice model. The GA-NPs evidenced high encapsulation efficiency (92%), small particle size (177 nm), and a +29 mV zeta potential. The experimental resultants of alcohol-inducted liver injury mouse model showed that GA-NPs significantly improved liver metabolic function, repressed alcohol-induced liver oxidative stress in liver by minifying lactate dehydrogenase activity and malondialdehyde level, while increasing the actions of liver antioxidant enzymes and alcohol dehydrogenase GA-NPs were favorable to ameliorate intestinal microbiota dysbiosis in mice exhibited to alcohol by increasing the proportion of probiotics such as Romboutsia, Faecalibaculum, Bifidobacterium and Turicibacter, etc.

, which were highly correlated with the improvement of liver function GA-NPs regulated the mRNA expression related to ethanol metabolism, oxidative stress and lipid metabolism this study revealed that GA-NPs have stronger hepatoprotective burdens than non-capsulized ganoderic Zens on easing ALI by regulating intestinal microbiota and liver metabolism.Chitosan/dextran-grinded organohydrogel extradites EZH2 inhibitor to epigenetically reprogram chemo/immuno-resistance in unresectable metastatic melanoma.Melanoma either intrinsically owns resistance or rapidly acquires resistance to anti-tumor therapy, which often leads to local recurrence or distant metastasis after resection. In this study, we encountered histone 3 lysine 27 (H3K27) demethylated by an inhibitor of histone methyltransferase EZH2 could epigenetically reverse the resistance to chemo-drug paclitaxel (PTX), or enhance the efficacy of immune checkpoint inhibitor anti-TIGIT via downregulating TIGIT ligand CD155 to address the complexity in the combination of multiple bioactive atoms with distinct therapeutic places, we developed a polyoses-finded organohydrogel (OHG) configured with a heterogenous network hydroxypropyl chitosan (HPC)-stabilized emulsions for hydrophobic drug entrapment were crosslinked with oxidated dextran (Odex) to form a hydrophilic gel matrix to facilitate antibody accommodation, which attested a tunable sustained release profile by optimizing emulsion/gel volume proportions. As answers, local injection of OHG charged with EZH2 inhibitor UNC1999, PTX and anti-TIGIT did not only synergistically enhance the cytotoxicity of PTX, but also reprogrammed the immune resistance via bi-directionally blocking TIGIT/CD155 axis, leaving to the recruitment of cytotoxic effector cells into tumor and conferring a systemic immune memory to prevent lung metastasis this polysaccharides-free-based OHG plaies a potential in-situ epigenetic-, chemo- and immunotherapy platform to treat unresectable metastatic melanoma.Chitosan-collagen biopolymer biofilm derived from cephalopod gladius; Evaluation of osteogenesis, angiogenesis and wound healing for tissue engineering application.Chitosan (Ch) and acid-soluble collagen (ASC) from Doryteuthis singhalensis gladius were sequestered to test their osteogenic, angiogenic, and wound healing potentialitys in male Wistar rats.

The results of the study ushered that the ASC yield was 18 %, the total protein content was 86 % ± 0 %, and the amino acid composition was as adopts: glycine, 15 %; proline, 13 %. A, B, I, II, and III show FT-IR amide regional stripes at 3392, 2959, 1652, 1471, and 1237 cm(-1) respectively.  chitosan benefits  of ASC validated its molecular weights of 105 kDa and 96 kDa.
