background: to evaluate the immunological properties of leishmania major excreted- secreted (e-s) products on the progress of leishmaniasis in susceptible balb/c mice. methods: promastigotes of the leishmania major were cultured and e-s products were collected during the culture preiod. groups of balb/c mice (n= 12) were immunized with e-s products or whole antigen. animals were challenged with...

background: leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic leptospira spp. a major challenge of this disease is the application of a basic research to improve diagnostic method. outer membrane proteins of leptospira are potential candidates that could be useful in diagnosis. among them the lipl41 is an immunogenic protein which is present on...

background:isolates of staphylococcus aureus express a myriad of adhesive surface proteins that play important role in colonization of the bacteria on nasal and skin surfaces, beginning the process of pathogenesis. the aim of this study was to screen several of the microbial surface components recognizing adhesive matrix molecules (mscramms) genes among the isolate of s. aureus from hospitalize...

introduction: ultra low dose (uld) morphine induces hyperalgesia which is mediated by excitatory gscoupled opioid receptors. this study was designed to investigate the development of tolerance to hyperalgesic effect of morphine. also we attempt to seek possible similarity, in view of gs proteins, between hyperalgesic effect of uld and hyperalgesic effect after tolerance to hd. method: male wist...

quantitative serum level measurements of gc , cp , c3 , igg , iga and 1gm were carried out on 102 patients with esophageal carcinoma following laryngectomy, in comparison with 66 healthy individuals as controls, in gonbad area, north east of iran. the procedure of radioinimuno-diffusion by standard m partigen plates was used for the measurements. a significant decrease was observed in gc level ...

antigenicity of proteins found in cow's milk is age dependent. this is primarily due to infants possessing a more permeable intestinal wall than that in adults. thus infants may acquire cow's milk allergy during their first year of life. while milk antigen specific ige may cause allergy in susceptible subjects, there is some evidence indicating that milk antigen specific igg may play some role ...

background and objectives:   iranian chronic hbv carrier’s population has shown a unique pattern of genotype d distri- bution all around the country. the aim of this study was to explore more details of evolutionary history of carriers based on structural surface proteins from different provinces. materials and methods: sera obtained from 360 isolates from 12 different regions of country were u...

introduction: g-proteins have an important role in the cell signaling of numerous receptors. the situation of g-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. here, the changes in the expression of g-protein subunits (gαi, gαs and gβ) were evaluated in hyperglycemic situation of pc12 cells as a cellular model...

background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...

background: infectious bursal disease virus (ibdv) causes a highly immunosuppressive disease in chickens and is a pathogen of major economic importance to the poultry industry worldwide. the vp2 protein is the major host-protective immunogen of ibdv and has been considered as a potential subunit vaccine against the disease. vp2 coding sequence was cloned in an inducible fungal vector and the pr...
