In this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. Cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. Proteins were then analysed on SDS polyacrylamide gels and densitometric...

Background: Analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. It is necessary to investigate the synthesis of these proteins during different stress condition...

Background: Lipopolysaccharides (LPSs) and several antigenic proteins of Brucella have been considered for preparation of diagnostic reagents and subunit vaccines. The objective of this study was to identify and compare immunogens of B. abortus S19 which induce humoral immune responses in human, goat and rabbit. Material and Methods: The bacterial whole cell extract was prepared in extraction b...

Objective: Oxidative stress that damages proteins result in aging and age related diseases. The aim of this study is to determine the effect of tocotrienol rich fraction (TRF) on the expression of proteins in oxidative stress-induced caenohabditis elegans (C.elegans) which has homologous genes to humans. Methods: The worms were treated with TRF prior to, after and continuously in separate group...

The aim of this study is to investigate antibacterial effects of immunodominant proteins isolated from the venom of Naja Naja Oxiana snake against Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa.The innate immune system is an important line of defense against bacterial diseases. Antibacterial proteins produced by snake venoms have recently attracted signifi...

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...

background: toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species toxocara canis and toxocara cati which parasitise canidae and felidae respectively. in paratenic hosts, larvae of these worms cause multiple organ damage. however, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear...

background and objective: obesity is an independent risk factor for cardiovascular diseases and diabetes. the abnormalities involved may be mediated by increased secretions of inflammatory proteins called adipocytokines by the adipose tissue. thus, monitoring adipocytokines during weight loss could be helpful in progress evaluation of weight reduction programs. since high-protein diets are cons...
