background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
the hydrophobic proteins of plant plasma membrane still remain largely unknown. for example in the arabidopsis genome, receptor-like kinases (rlks) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. a limited number of these proteins have appeard in protein pro...
in recent years considerable interest has been focused on the plasma amino acid patterns as a possible index of protein malnutrition, in children. thus a change in the ratio of non-essential to essential amino acids is considered to be significant in the development of protein malnutrition. the present paper reports a simplified and rapid chromatographic procedure for the determination of this ...
background: measuring of maternal serum pregnancy-associated plasma protein-a (papp-a) in first trimester can be a way for early detection of adverse prenatal outcome due to faulty placenta.objective: the aim was to determination of association between placental thickness in second trimester with low level of papp-a in first trimester.materials and methods: in this cohort study, serum papp-a of...

pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...
Protein-c deficiency is a rare disease that is two form: Homozygote and Heterozygote. Protein-c circulates in healthy adult Plasma is valu ranging from 70-140 Percent. Protein-C level in newborns are 20-40 Percent of normal adult level. Newborn with homozygote protein-C deficiency almost always manifest skin necrosis, fulminant purpura after birth and or central nervous system thrombosis. Mut...
in this study the plasma levels of lipid peroxidation (lp) products, protein carbonyls and antioxidant capacity of plasma as judged by ferric reducing ability of plasma (frap assay) were compared in adult and weanling rats treated with vitamin k1 phylloquinone).
Introduction & Objective: Ischemic injury of endothelium is associated with prostaglandin synthesis and platelet adhesion and aggregation, which may be associated with the release of aldehydes such as malondialdehyde (MDA). C-reactive protein and cardiac troponin I have been proposed as diagnostic markers of acute coronary syndromes. In this study, we compared the usefulness of plasma MDA as a ...
background: determination of oocyte fertilization and embryo quality are one of the most important purposes in art cycles. follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristics of the follicular fluid, such as pregnancy-associated plasma protein-a (papp-a), may play an important role in prediction of success rate of art. objectiv...
