2-acetyl benzimidazole was allowed to react with substituted aromatic aldehydes to get desired intermediate chalcones (2a-g), the cyclocondensation of these intermediates with hydrazine hydrate and phenyl hydrazine in two separate reactions yielded pyrazoline derivatives (3a-g &4a-g respectively). Among the synthesize compounds, six compounds were granted(More)
Exosomes are small extracellular vesicles secreted by variety of cell types such as neurons, astrocytes, and oligodendrocytes. It is suggested that exosomes play essential role in the maintenance of the neuronal functions and also in the clearance of amyloid-β (Aβ) from the brain. Aβ is well known to cause neuronal cell death, whereas little is known about(More)
Salivary alpha-amylase hydrolyses amylopectin in stages. At the end of the so-called second stage, there are present glucose, maltose, and a series of alpha-limit dextrins containing (1 leads to 4)- and (1 leads to 6)-alpha-D-glucosidic bonds. The structures of the limit dextrins containing a single (1 leads to 6)-bond were examined. Six such dextrins were(More)
By utilising the ability of some anionic serum proteins to bind to DNA-cellulose, at physiological pH and ionic strength, two such proteins have been purified and identified as immunoglobulin M (IgM) and complement component C4b-binding protein (C4BP). The method entails ammonium sulphate precipitation followed by QAE-Sephadex, DNA-cellulose and Sephacryl(More)
