Nanoparticle‐Functionalized Cellulose Through Biosynthesis‐Only Approach
Advanced Science, EarlyView.This study reports the first covalent incorporation of glucose‐modified carbon dots (Glu‐CDs) into bacterial cellulose (BC) via microbial fermentation, resulting in BC nanofibers that exhibit uniform cyan fluorescence. A 3D‐printable hydrogel (Glu‐CDs‐BC‐SA) is developed, facilitating the fabrication of fluorescent structures. This work demonstrates an

A simple and rapid method for measuring α-D-phosphohexomutases activity by using anion-exchange chromatography coupled with an electrochemical detector [PDF]
PeerJ, 2016 The interconversion of hexose-6-phosphate and hexose-1-phosphate can be directly analyzed by high-performance anion-exchange chromatography coupled with an electrochemical detector (HPAEC-PAD). Thus, this method can be used to measure the activities of N-

Advanced Science, EarlyView.A novel copper nanocluster coated with 4‐mercaptobenzeneboronic acid (CuMPBA) is developed to target bacterial polysaccharides for addressing complicated acute lung injury (ALI) caused by severe burns and early pulmonary infections. CuMPBA exhibits dual anti‐inflammatory and antibacterial mechanisms by: (a) binding and degrading toxic bacterial ...

Incorporation of N-Acetyl-d-glucosamine into Glycoproteins
Journal of Biological Chemistry, 1966 Abstract Fractionation of goat colostrum gave a 100- to 200-fold purified enzyme that catalyzed the transfer of N-acetylglucosamine from uridine diphosphate N-acetylglucosamine to certain glycoprotein acceptors. The latter were prepared from α1-acid glycoprotein (orosomucoid) and fetuin by treatment with purified sialidase, β-galactosidase, and ...

2,5-Deoxyfructosazine, a d-glucosamine derivative, inhibits T-cell interleukin-2 production better than d-glucosamine [PDF]
Carbohydrate Research, 2007 D-Glucosamine has been widely reported to have immunosuppressive actions on neutrophils, lymphocytes, and other cells of the immune system. However, under conditions used in biological experiments (e.g., neutral pH, and phosphate buffers), we have found that D-glucosamine self-reacts to form 2,5-deoxyfructosazine [2-(D-arabino-tetrahydroxybutyl)-5-(D ...

Journal of Applied Polymer Science, EarlyView.This manuscript describes the preparation of four types of spent coffee ground‐based adsorbents. Herein, the influence of the alkali pre‐treatment step (different NaOH concentrations) as well as the effect of crosslinking with epichlorohydrin is described.

Animal Research and One Health, EarlyView.This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Animal Research and One Health, EarlyView.The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.
