r-phycoerythrin (r-pe), a fluorescent protein from phycobiliprotein family, is isolated from red algae. conjugation of antibodies to r-pe facilitates multiple fluorescent staining methods. in the present study polyclonal antibodies and polyclonal f(ab')2 fragment antibodies were conjugated to r-pe by two different methods. the efficiency of the methods was evaluated using immunocytochemistry (i...
background: celiac disease is a common autoimmune disorder that is diagnosed based on clinical case identification, serological screening, and duodenal histology. however, the existence of mild clinical forms, such as seronegative cases with patchy atrophy and potential celiac disease, can make it difficult to determine a definitive diagnosis. the seronegative patients with celiac disease can i...
Introduction: Human immunodeficiency virus is the etiologic agent of immune system deficiency and the infected patients are susceptible to opportunistic infections and AIDS. Transmission of infection during blood transfusion and diagnosis of infection in hospitals and public health settings have steadily been a worldwide concern. Different techniques are now available for the diagnosis of HIV i...
The objective of the present study was oriented to produce purified polyclonal antibody to prepare a prolactin solid phase coated tubes radioimmunoassay system. In the present study, production of polyclonal antibodies was carried out through immunization of three healthy white male mature New Zealand rabbits with a highly purified sheep prolactin antigen. The obtained anti-sera was purified us...
One hundred and twenty-seven (0.3%) reactive serological tests for syphilis were obtained by routine examination of sera from 35,912 antenatal patients.Forty-eight (38%) of these reactive sera were associated with reactive fluorescent treponemal antibody and Treponema pallidum immobilization results and these patients were therefore considered to show serological evidence of treponemal infectio...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Soluble antigens from Histoplasma capsulatum in the mycelial and yeast phase were purified by gel filtration, fixed onto paper discs, and employed in an indirect immunofluorescence procedure to detect antibody in sera from individuals infected with H. capsulatum. The elution patterns of crude histoplasmin passed through Sephadex G-200 revealed two minor peaks of protein showing immunofluorescen...
Cucumber mosaic virus (CMV) is one of the causal agents of viral diseases that infected mint (Mentha spp.). CMV is a member of the cucumovirus genus in Bromoviridae family. The virus is naturally transmitted by aphids in a non-persistent manner.During growing season 2007-2008, leaf samples from plants of mint fields with symptoms of viral disease were collected in mint fieldas in Tehran provi...
