Low Levels of Chito-Oligosaccharides Are Not Effective in Reducing Deoxynivalenol Toxicity in Swine Jejunal Explants.
Juliana Rubira Gerez,Letícia Buck,Victor Hugo Brunaldi Marutani,Caroline Maria Calliari,Ana Paula Frederico Rodrigues Loureiro Bracarense +4 more
TL;DR: In conclusion, low levels of COS did not counteract DON-induced intestinal lesions, and the intestinal morphology of samples exposed to COS + DON remained similar to DON treatment.

Innovative Non-Thermal Technologies for Recovery and Valorization of Value-Added Products from Crustacean Processing By-Products—An Opportunity for a Circular Economy Approach
Ana Cristina De Aguiar Saldanha Pinheiro,Francisco J. Martí-Quijal,Francisco J. Barba,Silvia Tappi,Pietro Rocculi +4 more
TL;DR: In this paper, a summary of the main compounds that can be extracted from crustacean by-products, and of the results obtained by applying the main innovative non-thermal processes for recovering such high-value products.
Journal ArticleDOI
Effects of chitosan oligosaccharides on intestinal oxidative stress and inflammation response in heat stressed rats
TL;DR: Results indicated that COS may alleviate intestinal damage under heat stress condition, probably by modulating intestinal inflammatory response and oxidative status.

Optimization of Graft Polymerization and Performance of Carboxymethyl Chitosan / Polyacrylamide Flocculants
Emad Ali Soliman,El-Sayed A. Mohamed,Elsayed Mansour,Hammed Ahmed Mohamed Hassan,Noha Amaly,Mohammed Hassan,Emad A. Soliman +6 more
TL;DR: In this paper, an amphoteric graft copolymer-based flocculants were prepared by conventional peroxy graftcopolymerization of acrylamide (AM) onto carboxymethyl chitosan (CMCH) using potassium persulphate (PPS) initiator.

Altered enzymatic activity of lysozymes bound to variously sulfated chitosans
TL;DR: In this article, the effects of the variously sulfated chitosans on lysozyme activity and structure were investigated, and it was shown that the specific enzymatic activity of Lysozyme remained almost similar to the native protein after being bound to 6-O-sulfated Chitosan (6S-chitosin) and 3,6-Os-Sulfated (3,6S)-chitosa, but decreased greatly when bound to 2-N-6O-S-Chitosano (2,6

Food applications of chitin and chitosans
TL;DR: Application of chitinous products in foods and pharmaceuticals as well as processing aids has received considerable attention in recent years as exotic synthetic compounds are losing their appeal.
Journal ArticleDOI
Antibacterial action of chitosan
TL;DR: Fungal chitosan had significantly less antibiotic effect than CH and CL, and was shown to be concentration dependent with 0.1 mg/mL more effective than 2.0 and 5.0 mg/ mL.
Journal ArticleDOI
Chitosan: A Unique Polysaccharide for Drug Delivery
TL;DR: The aim of this review is to give an insight into the many potential applications of chitosan as a pharmaceutical drug carrier.
BookDOI
Chitin in nature and technology
TL;DR: Chitin has been a landmark for polysaccharides and modified chitins, besides chitin itself, to the point that three International Conferences on Chitin / Chitosan were convened (Boston, U.S. A. 1977, Sapporo, Japan 1982 and Senigallia, Italy 1985).

Antimicrobial effect of chitooligosaccharides produced by bioreactor
TL;DR: In this paper, the antibacterial effect of three kinds of chitooligosaccharides with relatively higher molecular weights (HMWCOS), medium molecular weight (MMWCOS), and lower molecular weight, respectively, was evaluated against various microorganisms.
