BACKGROUND Albizia adianthifolia is used traditionally in Cameroon to treat several ailments, including infectious and associated diseases. This work was therefore designed to investigate the antioxidant and antimicrobial activities of ethyl acetate extract, fractions and compounds isolated from the stem bark of this plant. METHODS The plant extract was prepared by maceration in ethyl acetate...

Human Onchocerca volvulus infection sera were found to recognize zwitterionic glycolipids of O. volvulus and to cross-react with those of other parasitic nematodes (Ascaris suum, Setaria digitata and Litomosoides sigmodontis). By the use of an epitope-specific monoclonal antibody, zwitterionic glycolipids of all these nematode species were observed to contain the antigenic determinant phosphoch...

There are no reported pathways of docosahexanoic (DHA) biohydrogenation; however, DHA is metabolized by ruminal microorganisms. In this study a 0.5mg pulse dose of uniformly 13C labeled DHA in ethanol was injected at 0h as a metabolic tracer. This study did not examine every fatty acid metabolite, but rather identified several saturated and trans-18:1 fatty acid metabolites and set a foundation...

Severe endothelial abnormalities are a prominent feature in sepsis with cytokines such as tumor necrosis factor (TNF) being implicated in the pathogenesis. As mimic to inflammation, human umbilical vascular endothelial cells (HUVEC) were incubated with TNF for 22 h, in the absence or presence of the -6 fatty acid (FA), arachidonic acid (AA), or the alternative -3 FA eicosapentaenoic acid (EPA) ...

Leaf traits, structure and water status of Conocarpus lancifolius, a Combretaceae were investigated under semi-arid conditions. The leaf traits examined included leaf area and thickness, stomatal distribution, sclerophylly, succulence and relative water content. Additionally, the types of secretory structures, histochemistry of trichomes, and chemical nature of the cuticlular waxes were evaluat...

Soybean seeds are an important source of vegetable oil and biomaterials. The content of individual triacylglycerol species (TAG) in soybean seeds is difficult to quantify in an accurate and rapid way. The present study establishes an approach to quantify TAG species in soybean seeds utilizing an electrospray ionization tandem mass spectrometry with multiple neutral loss scans. Ten neutral loss ...

Peanut testae (skins, seed coats) are an extremely low value by-product of peanut-blanching operations. Their commercial value is $12–20 per ton and their limited use is only as a minor component of cattle feed. Based on world in-shell peanut production of 29.1 million tons in 1999/2000 and an average skin content of 2.6%, world production of peanut skins can be estimated at over 750 000 tons a...
