Rat fibrinogen has been purified and compared with bovine and human fibrinogen with respect to a number of chemical characteristics, including molecular size, charge distribution, NH2-terminal amino acids, total amino acid composition, and interspecies immunological cross-reactivity. Although human and bovine fibrinogen demonstrated three nonidentical polypeptide chains by sodium dodecyl sulfat...

During the early phase of transport of exogenous fats, lymph and blood assume a milky appearance due to an increase of large fat particles, known as chylomicrons. Separation can be achieved by chemical means; protamine sulfate (1), toluidine blue (2), heparin and calcium chloride (3, 5), polyvinylpyrrolidone (4); however, ultracentrifugation (6) is the method commonly used. Chemical characteriz...

background artemisia aerial parts are well known for antimicrobial activities including anti malaria. objectives this study was carried out to evaluate the antimicrobial activity and chemical composition of essential oil from the seeds of artemisia aucheri boiss (asteraceae). materials and methods essential oil was extracted from the powdered seeds of artemisia aucheri by hydrodistillation. ant...

in this study, the nutritive values of treated walnut hull by neurospora sitophila were evaluated. the chemical composition of samples was evaluated by laboratory analysis.in vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate the metabolizable energy (me) content oftreat...

scented rose species are very important in the genus rosa due to their use in highly-prized essential oil production and as garden roses. the fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. a comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly damask r...

the present work was designed to study the antioxidant activity and to identify the main active components of the essential oil of ajowan (trachyspermum copticum) fruit. gc and gc-ms analyses of the essential oil showed the presence of eight compounds. the main constituents of the oil were thymol (43.7%), p-cymene (26.8%), and γ-terpinene (24.9%). the antioxidant and free radical scavenging act...
