Woody tissues consist primarily of a mixture of cellulose, hemicelluloses, and lignin. Covalent bonds between lignin and polysaccharides likely play a central role in determining the mechanical and physical properties of wood. Intact and defined lignin-polysaccharide networks have not been isolated in large quantities because of the recalcitrance of lignin, which demands harsh chemical treatmen...

Site-specific assembly of gold nanoparticles on a polysaccharide surface was accomplished via a straightforward method exploiting interfacial polymer blends, selective protein adsorption and electrostatic interaction. The method could be useful in further applications due to the universal nature of the utilized phenomena.

inflammation is a part of the non-specific immune response which occurs in reaction to any type of injury. medicinal mushrooms have had application in various disorders including cancer, liver injuries, inflammation and diabetes. in the present study, the anti-inflammatory effects of the aqueous extracts of medicinal mushrooms (fomes fomentarius, ganoderma applanatum and trametes hirsuta) were ...

Lycium barbarum and Ganoderma lucidum, highly valued Chinese medicinal fruit and mushroom, have attracted more and more attention because of the antitumour activities they have shown, and polysaccharides are considered their most important functional constituent. Forming new compounds of L. barbarum polysaccharides, isolated from dried L. barbarum fruits, and G. lucidum polysaccharides, derived...

Hemagglutinating antibody responses of Lewis-Wistar and Sprague-Dawley rats to graded doses of type-specific pneumococcal polysaccharide were measured. Rats given a small dose (0.2 to 50 mug)of type 1 or 8 polysaccharide intraperitoneally developed type-specific hemagglutinating antibody. Rats given larger doses of polysaccharide (greater than or equal to200 mug) did not develop detectable hema...

In the course of genetic studies, a mutant. strain of Escherichia coli was developed which is characterized by rapid fermentation and oxidat.ion of maltose but not of glucose. Since this mutant offered an excellent opportunity to invest,igat,e the so called direct utilization of disaccharides (l), a study of the enzyme systems involved in maltose decomposition was undertaken. Experiments with d...

Invasive bacterial meningitis caused by Neisseria meningitidis can be prevented by active immunization with meningococcal polysaccharide or polysaccharide-protein conjugate vaccines. In a tetravalent A/C/Y/W-135-DT meningococcal conjugate vaccine vial, or in a final formulated bulk, accurate identification and quantification of each polysaccharide are critical in product release. Determination ...

The primary attachment to polymer surfaces followed by accumulation in multilayered cell clusters leads to biofilm production of Staphylococcus epidermidis, which is thought to contribute to virulence in biomaterial-related infections. We purified a specific polysaccharide antigen of biofilm-producing S. epidermidis 1457 and RP62A, which was recently shown to have a function in the accumulative...
