Acid Ga Resveratrol Gelatin Gel Chi Effects Beef Preservation
The effects discovered that CA had the most significant improvement effect on fresh beef preservation. The combination of GEL-CHI-GLY-CA preserved the color of the beef better and stayed the increase of the total volatile base nitrogen, even though its total phenolic content lessened at a faster rate during beef preservation. GA also amended the preservation effect as on the 12th day of storage, the beef samples covered with GEL-CHI-GLY-GA had the lowest thiobarbituric acid reactive substances (0 mg Malondialdehyde (MDA)/kg) and total viable count (6 log cfu/g). On the whole, though RES showed an improvement on beef preservation, the improvement was not as good as the other two polyphenols. After 12 days of storage, the beef samples covered with GEL-CHI-GLY-RES had a higher pH value (6) than the other two polyphenol treatmed groups the three polyphenol-bestowed combinations increased the shelf life of beef by approximately 3-6 days equated to the control group (addressed GEL-CHI-GLY with distilled water).The effectiveness of ursolic acid niosomes with chitosan coating for prevention of liver damage in mice rushed by n-nitrosodiethylamine.
Ursolic acid (UA) is a pentacyclic triterpene carboxylic acid which produces various effects, admiting anti-cancer, hepatoprotective, antioxidant and anti-inflammatory UA demonstrates poor water solubility and permeability. Niosomes have been covered to improve the bioavailability of low water-soluble drugs. Amino Acids directed to investigate the protective action of UA-niosomes with chitosan levels against liver damage caused by N-Nitrosodiethylamine (NDEA). UA niosomes were prepared applying a thin layer hydration method, with chitosan being added by vortexing the potpourris. For the induction of liver damage, the mice were administered NDEA intraperitoneally (25 mg/kgBW). They were reached niosomes orally (11 mg UA/kgBW) seven and three days prior to NDEA induction and subsequently once a week with NDEA induction for four workweeks. The resultants showed that chitosan stratums increased the particle sizings, PDI, and ζ-voltages of UA niosomes.
UA niosomes with chitosan coating tightened the SGOT and SGPT level. The histopathological evaluation of liver tissue presented an improvement with trimed bile duct inflammation and decreasing pleomorphism and enlargement of hepatocyte cell karyons in UA niosomes with the chitosan coating treated group. It can be concluded that UA niosomes with chitosan coating amended the efficacy of preventive UA therapy in liver-damaged mice induced with NDEA.pH-sensitive O-carboxymethyl chitosan/sodium alginate nanohydrogel for raised oral delivery of insulin.Oral drug delivery is conceived the most preferred mode of treatment because of its high patient compliance and minimal invasiveness the oral delivery of protein drug has been a difficult problem which curtails its application due to the unstable and inefficient penetration of protein in the gastrointestinal tract. In this study, a novel OCMC/SA nanohydrogel was organised by using of O-carboxymethyl chitosan (OCMC) and sodium alginate (SA) to solve the problem. The OCMC/SA had a typical nanostructure, which was helpful to increase the specific surface area and raised the bioavailability of the drugs.
OCMC/SA had a high drug loading capacity and realized passive drug targeting function by responding to the different pH value of the microenvironment. It could have a certain protective effect on drugs in strong acid settings, while its structure got loosed and effectively published drugs in intestinal conditions. OCMC/SA could release the drug for >12 h, and the relinquished insulin could maintain high activity. OCMC/SA nanohydrogel evinced promising answers in type 1 diabetic rats, and its pharmacological bioavailability was 6 %. In conclusion, this study maked a novel OCMC/SA nanohydrogel, which had a lot of exciting characteristics and provided a new strategy for oral drug delivery.Construction of CuO/Cu-nanoflowers diluted on chitosan-deduced porous carbon for high energy density supercapacitors.
