Sulfated Cyclocarya Paliurus Polysaccharide Sorchestrates the Gut Microbiome to Mobilize a Host‐Derived 12‐HEPE Against Ulcerative Colitis

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A sulfated polysaccharide (SCP) from Cyclocarya paliurus alleviates ulcerative colitis by reshaping the gut microbiome. This remodeled microbiota orchestrates the upregulation of the host‐derived lipid 12‐HEPE, which directly inhibits the TLR4/NF‐κB pathway to suppress inflammation.

A Purification‐Free Strategy for the Electrochemical Oxidation of the Primary Hydroxy Group in Glycopyranosides

ChemElectroChem
An operationally simple protocol for the electrochemical oxidation of the primary hydroxy group in glycopyranosides is presented. The strategy uses aqueous ammonia as a base and electrolyte, reticulated vitreous carbon (RVC) electrodes, and TEMPO as a ...

Determination of Uronic Acids in Cellulosic Materials

Textile Research, 1940
Naturally-occurring cellulosic fibres appear to be a more or less intimate association of cellulose with other constituents, generally referred to as incrusting substances. A portion of these extraneous materials appears to be com posed of uronic acids, presumably contained in the pectic substance of the fibres.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, Volume 4, Issue 3, Page 335-346, August 2026.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Effects of Lactobacillus‐Mediated Functionalization of Dendrobium officinale Polysaccharides: A Study From Physicochemical Properties and Structural Changes to Anti‐Inflammatory Activity

eFood, Volume 7, Issue 4, August 2026.
Lactic acid bacteria (LAB) fermentation cleaves specific glycosidic bonds in Dendrobium officinale polysaccharides (DOPs), reducing molecular weight and enhancing anti‐inflammatory activity through regulation of inflammatory cytokines, oxidative stress, and intestinal barrier function.

Dynamics of Heparin Translocations Through Solid‐State Nanopores

ELECTROPHORESIS, Volume 47, Issue 8, Page 799-808, August 2026.
Carbohydrates can be detected with solid‐state nanopores, but their kinetics of voltage‐driven passage are fast. To better understand the dynamics of passage of these biomolecules and the role of electrophoresis and electroosmosis, we studied the translocation characteristics of heparin as a function of salt concentration, pH and voltage polarity ...

Dietary Lycium barbarum Polysaccharides Support Retinal Redox Homeostasis Through Gut Microbiota–Associated Metabolic Modulation

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Summary schematic illustrating the proposed association among dietary LBP intake, gut microbiota remodeling, fecal metabolic pathway modulation, retinal metabolite changes, and retinal antioxidant signaling. The model summarizes associations observed in the present study and does not imply direct causal proof.

Isolation and characterization of a novel uronic acid-containing acidic glycosphingolipid from the ascidian Halocynthia roretzi

Journal of Lipid Research, 2007
A novel uronic acid-containing glycosphingolipid (UGL-1) was isolated from the ascidian Halocynthia roretzi. UGL-1 was prepared from chloroform-methanol extracts and purified by the use of successive column chromatography on DEAE-Sephadex, Florisil, and ...
