β-1,3 Glucan Sulfate, but Not β-1,3 Glucan, Induces the Salicylic Acid Signaling Pathway in Tobacco and Arabidopsis
Sulfate substituents naturally occurring in biomolecules, such as oligosaccharides and polysaccharides, can play a critical role in major physiological functions in plants and animals. We show that… Expand

Characterization of the structural requirements for a carbohydrate based anticoagulant with a reduced risk of inducing the immunological type of heparin-associated thrombocytopenia.
HAT is the most frequent drug induced immune-thrombocytopenia. We recently identified multimolecular PF4/heparin complexes as the major antigen. In order to evaluate the structural requirements for… Expand

Pythium aphanidermatum: culture, cell-wall composition, and isolation and structure of antitumour storage and solubilised cell-wall (1----3),(1----6)-beta-D-glucans.
Under optimal conditions for the culture of the fungus Phytium aphanidermatum, no polysaccharides were excreted into the medium. The mycelium contained up to 38% of a slightly branched, storage… Expand

Anticoagulant sulfated polysaccharides: Part I. Synthesis and structure–activity relationships of new pullulan sulfates
In order to develop new anticoagulants as potential heparin alternatives, two pullulans with different molecular weight (MW) were used as starting polymers for the partial synthesis of a structurally… Expand

LaPSvS1, a (1-->3)-beta-galactan sulfate and its effect on angiogenesis in vivo and in vitro.
LaPSvS1, a highly sulfated branched (1-->3)-beta-galactan was prepared from the arabino-galactan from Larix decidua Miller by partial hydrolysis and subsequent sulfation with SO(3)-pyridine in DMF.… Expand

Isolation and Some Properties of an UDP-Glucose: 2-Hydroxyflavanone-6(or 8)-C-Glucosyltransferase from Fagopyrum esculentum M. Cotyledons
Summary A crude enzyme preparation from Fagopyrum esculentum M. cotyledons was shown to catalyze the glucosyl transfer from UDP-Glc to the 6(or 8)-C atom of 2-hydroxyflavanones thereby forming a… Expand

Changes in the composition of cotton fibre cell walls during development
Purified cell walls, prepared from cotton fibres (Gossypium arboreum L.) at different growth stages, were subjected to successive extractions to give pectic, hemicellulosic, and α-cellulosic… Expand

Investigation of the Origanum onites L. essential oil using the chorioallantoic membrane (CAM) assay.
The in vivo test on the chorioallantoic membrane of the fertilized hen's egg (CAM assay) is a current method to determine antiangiogenic, antiinflammatory activity and toxic effects of individual… Expand
