background and objectives: tuberculosis (tb) is a major problem in the world. treatment and control of tb needs detection of the mycobacterium tuberculosis (mt) in the proper samples. while smear doesn’t have enough sensitivity, culture and pcr are expensive, time consuming and unavailable in many centers. recent development of a rapid tb antigen detection test (prtbk) at pasteur institute of i...

throughout the world, many migrant and mobile populations are at elevated risk for hiv. iran has a large immigrant population from neighboring afghanistan; however, few data exist on the prevalence of hiv in this community. in 2008, we conducted a study to assess the presence of hiv infection among 477 immigrants in a town to the northeast of tehran using a rapid test in the field. hiv prevalen...

Background With the advent of rapid industrialization, several chemicals are released in the air, water and soil. Chemical elements play a crucial role in male reproduction. Heavy metals exposure can adversely affect male fertility and result in severe impairment of testicular functions including germ cell death and inhibition of testicular steroidogenesis. The aim of this study was to investig...

Sera from 628 nonsyphilitic individuals were tested with the Rapid Plasma Reagin-Card, Fluorescent Treponemal Antibody-Absorbed, and Hemagglutination Treponemal Test for Syphilis tests to ascertain the comparative specificity of these tests. Many sera were also tested with the quantitative Venereal Disease Research Laboratory test. Sera included in the study were from both normal individuals an...

The fluorescent antibody method of Coons and Kaplan (1950) has led to numerous studies of its practical application, many directed to the problem of rapid and accurate identification of microorganisms (Goldman, 1953, 1957; Moody, Goldman, and Thomason, 1956; Thomason et al., 1956, 1957; LaBrec, Formal, and Schneider, 1959; Winter, and Moody, 1959). Moody, Ellis and Updyke (1958) showed that ser...

Rapid and quantitative sensing of aflatoxin B1 with high sensitivity and specificity has drawn increased attention of studies investigating soybean sauce. A sensitive and rapid quantitative immunochromatographic sensing method was developed for the detection of aflatoxin B1 based on time-resolved fluorescence. It combines the advantages of time-resolved fluorescent sensing and immunochromatogra...

BACKGROUND Rabies is an acute fatal encephalitis caused by all members of the Lyssavirus genus. The first human rabies survivor without benefit of prior vaccination was reported from Milwaukee in 2005. We report a second unvaccinated patient who showed early recovery from rabies and then died accidentally during convalescence, providing an unparalleled opportunity to examine the histopathology ...

The high infectivity, difficulty to diagnose, and drug resistance of melioidosis limited the timeliness treatment. Lateral flow assay (LFA) was operated in this research provide an instant diagnosis method, a fast antibody rapid matching test strategy based on LFA developed select most sensitive specific pair antibodies. Compared traditional ELISA new limits pairing time 3 h without any complex...
