The N-glycosylation pattern of the neural cell adhesion molecule (NCAM), isolated from brains of newborn mice, has been analyzed. Following digestion with trypsin, generated glycopeptides were fractionated by serial immunoaffinity chromatography using immobilized monoclonal antibodies specifically recognizing polysialic acid (PSA) units or the HNK1-carbohydrate epitope. Subsequent analyses of t...

The valorization of industrial lignin essentially requires fractionation resulting in lower structural heterogeneity and polydispersity. So far, extensive approaches based on extraction with solvents, gradient acid precipitation, membrane-based filtration have been developed to reduce the polydispersity technical lignins. However, most reports tend overlook fraction that bonded carbohydrates or...

Lignocellulosic biomass is a cheap raw material that, thanks to its high carbohydrate content, can be used in fermentation produce biofuels, biogas and other compounds. Its complex structure, including cellulose, hemicellulose lignin, requires prior treatment of the facilitate hydrolysis simple sugars. Today, only partially utilized generates about 14% world's energy. This because most commonly...

background: premenstrual syndrome (pms) is one of the most common disorders in women in reproductive age. the study aimed to assess the effect of carbohydrate-rich supplements and diets on premenstrual syndrome. methods: the study was conducted within two stages. first stage was descriptive cross sectional investigation to find out frequency and subjects diagnosed as pms according to the apa cr...

In the semi-arid part of northern Tanzania, the native tropical woodland is undergoing a rapid conversion into agricultural land. This has resulted in drastic ecological changes in the region. This study was undertaken to investigate the effects of these changes in land use systems on the amount and composition of SOM in bulk soil samples and size separates. Samples were collected from the uppe...

The study was undertaken to investigate the hypolipidemic and hepatoprotective effects of the different fractions (Petroleum ether, ethyl acetate and chloroform) of ethanolic extract of Brassica oleracea. The different fractions of extract were administered intraperitoneally as a single dose of 150 mg/kg body weight to alloxan induced diabetic rats and found to reduce blood lipid level (Total c...
