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

Immunosuppressive Effects of Glucosamine [PDF]
Journal of Biological Chemistry, 2002 Glucosamine is a naturally occurring derivative of glucose and is an essential component of glycoproteins and proteoglycans, important constituents of many eukaryotic proteins. In cells, glucosamine is produced enzymatically by the amidation of glucose 6-phosphate and can then be further modified by acetylation to result in N-acetylglucosamine ...

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 ...

A Genetically Encoded Assay System to Quantify O-GlcNAc Transferase (OGT) Activity in Live Cells. [PDF]
Angew Chem Int Ed EnglA genetically encoded, imaging‐based reporter enables direct measurement of O‐GlcNAc transferase (OGT) activity in living cells. The system exploits OGT‐dependent proteolysis of HCF‐1 to drive nuclear and cytoplasmic redistribution of fluorescent signals, allowing cell‐by‐cell spatially resolved quantification of OGT activity.

Glucosamine-mediated immunomodulation after stroke is sexually dimorphic
Brain, Behavior, & Immunity - Health, 2020 Growing evidence suggests that galectin-3 (Gal-3) is instrumental in orchestrating innate immune response and microglia activation following different brain pathologies. However, its role remains controversial. We recently showed that a readily available

Enzymes acting on glucosamine phosphates [PDF]
Biochimica et Biophysica Acta, 1956 Abstract The chemical synthesis of α-acetylglucosamine- i -phosphate and some of its properties are described. From kidney or liver, enzymes have been obtained which catalyse the following reactions: 1. α- acetylglucosamine i - phosphate ⥮ acetylglucosamine -6- phosphate (1) 2.

Неврология, нейропсихиатрия, психосоматика, 2012 The paper gives an update on therapy for osteoarthrosis (OA). Symptomatic sustained-release drugs, particularly structural analogues of the cartilage (glucosamine and chondroitin sulfate), that have the weightiest body of evidence is noted to occupy a ...

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.
