Rabbit alveolar macrophages express a plasma-membrane receptor that recognizes glycoprotein ligands bearing terminal mannose, fucose or N-acetylglucosamine residues. Macrophage membranes were washed extensively with buffers containing high salt and mannose or EDTA to remove endogenously bound ligand, before Triton X-100 extraction. The extracts were chromatographed on mannose-Sepharose. Elution...

Experiments were conducted in which d-mannose was supplied to mature Beta vulgaris L. (sugar beet) leaves, via the transpiration stream, to perturb photosynthetic carbon allocation by sequestering cytosolic Pi. Biochemical and enzymic analyses conducted on this tissue indicated that mannose 6-P was present, that it was only slowly metabolized, and that after a 24-hour pretreatment sugar metabol...

Bacteroides fragilis has been isolated from several human and non-human monomicrobial and mixed infections. In this study, some virulence markers and the antimicrobial susceptibility of bacteria of the B. fragilis group isolated from children's stools were evaluated. All the 64 isolates showed the following characteristics: capsulated, beta-hemolytic, hydrophilic, and serum-resistant. Only, 24 ...

Using gas-liquid chromatography, we measured five mannose in the serum of six nondiabetic patients with autopsy-proven invasive candidiasis. In all patients serum mannose concentrations were higher than mannose levels found in serum from normal adults and children or from patients with catheter-associated candidemia, mucosal candidiasis, and other mycoses. Spinal fluid from two patients with Ca...

A novel mannose-specific lectin, named CGL1 (15.5 kDa), was isolated from the oyster Crassostrea gigas. Characterization of CGL1 involved isothermal titration calorimetry (ITC), glycoconjugate microarray, and frontal affinity chromatography (FAC). This analysis revealed that CGL1 has strict specificity for the mannose monomer and for high mannose-type N-glycans (HMTGs). Primary structure of CGL...

In this study, D-mannose was used to synthesize poly-D-mannose using a one-pot method. The molecular weight, degree of branching, monosaccharide composition, total sugar content, and infrared spectrum were determined. addition, we evaluated the safety bioactivity including anti-pathogen biofilm, antioxidant, anti-inflammatory activity. results showed that mixture four components with different ...

Abstract Aims This study investigated the influence of climate and soil on exudation rate polysaccharide composition aerial nodal root mucilage from drought-resistant drought-susceptible maize varieties. Methods Two varieties were grown in two different soils (sandy-clay loam Acrisol Luvisol) under simulated climatic conditions their agroecological zones origin Kenya Germany. The roots was quan...
