We used PCR assays to determine the etiology of genital ulcers in patients presenting to a sexually transmitted disease clinic in Dakar, Senegal, and evaluated the ability of two PCR tests (groEL and recD) and two serological tests (adsorption enzyme immunoassay [EIA] and lipooligosaccharide [LOS] EIA) to detect current Haemophilus ducreyi infection. We found that in this population, H. ducreyi...

Glucocorticoids play a key role in mediating stress responses in vertebrates. Corticosterone (CORT) is the main glucocorticoid produced in amphibians, birds, and reptiles, and regulates several metabolic functions. The most common methods for quantifying CORT are competitive binding immunoassays: radioimmunoassay (RIA) and enzyme immunoassay (EIA). RIA has been broadly used since the 1980’s but...

The clinical observation has been made that there might be an unacceptable number of false-positive enzyme immunoassay (EIA) test results for IgM among persons suspected of having coccidioidomycosis. Patients with a positive result for IgM by EIA are thought to have a diagnosis of acute coccidioidomycosis. However, this study found that 82% of patients with an IgM-positive and IgG-negative EIA ...

Exercise-induced asthma (EIA) is the name used to describe the transitory increase in airways resistance which follows vigorous exercise in most patients with asthma [1). EIA has been recognized since ancient times, but the first modem clinical description was given by JoNES et al. [2] of Liverpool, UK in 1962. Exercise is acknowledged by many paediatricians to be the most common cause for an a...

We propose a distortion-corrected integral imaging (II) 3D display system based on lens array holographic optical element (LAHOE). The LAHOE is used as projection screen. beam of the parallel light. Hence, consists spatial light modulator, reverse lens, relay element, and telecentric lens. acquired data reconstructed image II are symmetrically related to each other. Therefore, there distortion ...

Although the physical effects of tobacco on an individual are well-known, the impacts that smoking has on social skills of family members are less understood. The ability for children to identify emotions is crucial for normal social functioning, and the impact of parental tobacco use during child development of this skill is not known. The proposed research compares parentreported tobacco use ...

Heparin-induced thrombocytopenia (HIT) is caused by platelet-activating antibodies that recognize platelet factor 4//heparin (PF4/H) complexes. According to the "iceberg model," only a subset of anti-PF4/heparin antibodies of IgG class evincing strong platelet-activating properties cause clinical HIT. Since many centers rely predominantly on an anti-PF4/polyanion enzyme-immunoassay (EIA) to dia...

We developed a direct enzyme immunoassay [EIA; Enzygnost Influenza A(Ag) and Enzygnost Influenza B(Ag)] for the direct detection of influenza A and B virus antigens in nasopharyngeal secretion specimens (NPS). The test is performed without sonification of specimens, and results are obtained within 4 h. A direct comparison between direct EIA and quantitation of virus shedding for influenza A and...
