background: the purity and correct folding of a recombinant protein is critical for any structural, biochemical and vaccine design studies. plasmodium vivax duffy binding protein-ii is a leading vaccine candidate for vivax malaria. in the present study, the purification process of recombinant dbp-ix (a variant form of pvdbp-ii) was optimized to achieve the highest yield and purity. moreover, na...

the binding of drugs by plasma proteins is an important phenomenon, because it influences the size of the free fraction of the drugs in plasma. in this study the influence of dipyridamole (dp) on the protein binding of propranolol (pl) and pl on the protein binding of dp were studied alone and in the presence of nicotine (nc).        the equilibrium dialysis was employed for protein binding stu...

background: acanthamoeba keratitis develops by pathogenic acanthamoeba such as a. pal­es­tinen­sis . indeed this species is one of the known causative agents of amoebic keratitis in iran. mannose binding protein (mbp) is the main pathogenicity factors for developing this sight threatening disease. we aimed to characterize mbp gene in pathogenic acanthamoeba isolates such as a. palestinensis . m...

background: acanthamoeba castellanii is the important cause of amoebic keratitis in iran. the key molecule in pathogene­sis of acanthamoeba keratitis is mannose binding protein (mbp) led to adhesion of amoeba to corneal epithelium. subse­quent to adhesion other cytopathic effects occur. the goal of this study was to identify the molecular characterization of a gene encoding mbp in an iranian is...

host innate immunity can affect the clinical outcomes of helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and malt lymphoma. nucleotide binding oligomerization domain (nod)-1 and -2 are two molecules of innate immunity which are involved in the host defense against h. pylori . this study aimed to evaluate the effect of the expression level of nod1 and n...

the histone-like protein hu is the most-abundant dna-binding protein in bacteria. the hu protein non-specifically binds and bends dna as a hetero- or homodimer, and can participate in dna supercoiling and dna condensation. it also takes part in dna functions such as replication, recombination, and repair. hu does not recognize any specific sequences but shows a certain degree of specificity to ...

conclusions the established method has an acceptable performance in quantifying yb-1. in addition, serum yb-1 may aid in the diagnosis of hcc. results the developed method was linear to 150 μg/l of yb-1 with a minimum detection limit of 0.01 μg/l. the average recoveries were between 93.9% and 109.0%. the mean intra- and inter-assay coefficients of variation (cvs) were 4.0-4.8% and 8.2-10.2%, re...

objective(s) staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. antibiotic therapy for vancomycin resistant s. aureus (vrsa) can not promise the eradication of infections. since adhesion is the major route of infections, adhesin based vaccine could suppress s. aureus infections. fibronectin binding protein a (fnbpa) and clumping factor a (clfa) ...
