Cellulose benzoate propionates (CBzP) were prepared via a staged addition of Pr2O followed by Bz2O to cellulose dissolved in tributylmethylammonium dimethyl phosphate (TBMADMP) providing regioselectively substituted cellulose esters in which the benzoate was preferentially installed at C2 and C3. By systematically varying the DSPr, DSBz, and DSOH (DS = degree of substitution), we synthesized CBzP that could potentially be utilized as a unique compensation film in optical displays.In the present study, chitooligosaccharide (COS) and salicylic acid (SA) conjugates were synthesized using H2O2-induced grafting polymerization and oxidized alginate (OA) and gelatin hydrogels were fabricated using Schiff's base reaction. To confirm the synthesis and improved activity of the COS-SA conjugates, polyphenol assays, ultraviolet absorbance, NMR, and antioxidant activity tests were all conducted. The results showed that the COS-SA conjugates were completely synthesized and improved antioxidant activity. OA was synthesized using a periodate method and a hydrogel was obtained at a mixed ratio of 37 via crosslinking between the aldehyde group of the OA and the amine groups of gelatin with COS-SA conjugates. In a cytotoxicity and wound healing model, the hydrogels with COS-SA conjugates did not exhibit cytotoxicity and exhibited wound healing activity in a mouse model. These results provide evidence that OA and gelatin hydrogels with a COS-SA conjugate can be successfully used for wound healing applications.Injectable chitosan hydrogels exhibit excellent biological properties for application in biomedical engineering, however most of these hydrogels have limited applicability because "Swelling" can induce volume expansion of conventional hydrogels implanted in the body damages the surrounding tissues. Here, we report a new "Nonswelling" pentenyl chitosan (PTL-CS) hydrogel via N‒acylation reaction to graft an UV crosslinkable short hydrophobic alkyl chain (n‒pentenyl groups). The incorporated pentenyl groups can be crosslinked by UV irradiation to form hydrophobic chains via combination termination, which generate strong hydrophobic effect to extrude the excess water in hydrogel, resulting in a "Nonswelling" state at biological temperature. Furthermore, the PTL-CS solution showed no cytotoxicity in vitro and minimally invasive treatment in vivo demonstrated the PTL-CS hydrogel no adverse effects in a rat model. The nonswelling injectable and UV crosslinkable chitosan hydrogel hold potential applications in smart biomaterials and biological engineering as well as providing a new natural hydrogel in minimally invasive tissue engineering..The goal of this work was to assess the usability of yeast glucan particles (GPs) as carriers for curcumin and determine the beneficial effect of a pharmacological composite of curcumin in GPs on dextran sulfate sodium induced colitis in rats. The assessment of the anti-inflammatory effect of particular substances was evaluated on the basis of the calculated disease activity index and by assessment of cytokines and enzymes from the gut tissue - tumor necrosis factor α (TNF-α), transforming growth factor β1, interleukin (IL)-1β, IL-6, IL-10, IL-17, catalase, superoxide dismutase 2, myeloperoxidase (MPO), and matrix metalloproteinase 9. Composites of GPs with incorporated curcumin showed promising results with the capability to lower symptoms of colitis and significantly decrease the production of pro-inflammatory cytokines TNF-α, IL-1β, IL-6, and the activity of MPO, as well. The anti-inflammatory effect of the composites was greater than those of pure GPs or curcumin.Betaxanthins are nitrogenous plant pigments belonging to the family of betalains and they are known for their health-promoting effects and fluorescent properties. A novel biotechnological approach in the synthesis of these compounds has allowed the synthesis of high amounts of known betalains and of novel, tailor-made betalains through the condensation of the structural unit - betalamic acid - with amine groups of different compounds. Here we describe the synthesis and characterization of chitosan-betaxanthin, the first fluorescent polymeric betaxanthin which forms nanoparticles and that might combine the fluorescent properties of betalains and the properties of chitosan, a sugar polymer widely used with medical purposes. In addition, glucosamine, the structural unit of chitosan, and its stereoisomer galactosamine were shown to condense in solution with betalamic acid. This produced novel molecules with spectral and in vivo antioxidant and anti-aging properties similar to those of biological betaxanthins, which are the first sugar-derived betaxanthins described.Pyrodextrins were prepared from acidified waxy and normal tapioca starches (pH∼3) at 3 temperatures (130, 150 and 170 °C) and 3 times (1, 2 and 4 h) to determine their in vitro digestibility and molecular structure. Pyrodextrin from waxy tapioca starch produced at 170 °C/4 h had 5% higher total indigestible carbohydrate than pyrodextrin from normal tapioca starch (45.2 % and 40.4 %, respectively) as determined by a modified AOAC Method 2011.25. The low-molecular weight indigestible carbohydrate content at this condition was also higher for waxy tapioca starch than normal tapioca starch (40.6 % and 34.9 %, respectively). Selleckchem SRT1720 Gel permeation chromatography and nuclear magnetic resonance spectroscopy were used to study changes in molecular structure and correlate with digestibility of the pyrodextrins. Molecular size distribution indicated that waxy tapioca starch underwent thermal modification more readily than normal tapioca starch. Non α-1,4/α-1,6 glucosidic linkages were increased in the pyrodextrins with increasing in indigestible carbohydrate content.Fucose-containing oligosaccharides (FCOs) have important applications in the food, medicine, and cosmetics industries owing to their unique biological activities. The degradation of microbial fucose-containing exopolysaccharide (FcEPS) is a promising strategy for obtaining FCOs, and bacteriophage-borne glycanase is a useful tool for degrading FcEPS. Here, we aimed to obtain FCOs using bacteriophage-borne glycanase to depolymerize FcEPS from Enterobacter sakazakii. The FcEPS was mainly composed of l-fucose (42.72 %), d-galactose (20.59 %), and d-glucose (21.81 %). Based on the results of nuclear magnetic resonance and mass spectrometry, the obtained FCOs were disaccharide fragments with backbones of β-d-Glcp-(1→4)-β-l-Fucp and α-d-Galp-(1→3)-β-l-Fucp, respectively. So far, few studies of disaccharides prepared from FcEPS have been reported. This study demonstrated that the FcEPS of E. sakazakii was a reliable fucose-containing disaccharide source and that bacteriophage-borne glycanase was an effective degradation tool for obtaining FCOs fragments from FcEPS.
