The role of lung mast cells in exercise-induced asthma (EIA) is controversial. To investigate whether the skin mast cell releasability is increased after exercise in EIA, 49 young atopic men with or without asthma took part in a free-running test for 6 min and were given skin prick tests using morphine, a mast cell secretagogue, before and after the exercise. The mean diameters of the wheal ind...
In a multicenter cooperative study, an enzyme immunoassay (EIA) using purified antigen of lymphadenopathy-associated virus was compared with radioimmune precipitation (RIP) for detection of antibody to human immunodeficiency virus (HIV) in 634 patients with acquired immunodeficiency syndrome or related conditions, 687 apparently healthy persons at risk for HIV infection, 93 controls with cancer...
Environmental impact assessment (EIA) has been widely recognized as a crucial instrument for sound decision-making that will promote environmental conservation and sustainable development. International jurisprudence clarified the obligation of EIA under customary international law, especially concerning its legal status, threshold standards, procedural requirements, well issue State responsibi...
Tissue samples of three endometrial carcinomas, seven ovarian carcinomas, and 24 mammary carcinomas were analyzed for estrogen receptor (ER) by enzyme immunoassay (EIA) and a conventional dextran-coated charcoal (DCC) method. In addition, ER and progesterone receptor were assayed by DCC only in 68 ovarian carcinoma specimens. All three endometrial cancer specimens showed elevated ER values by b...
An immunoglobulin M (IgM) antibody capture enzyme immunoassay (MAC-EIA) was developed for the rapid and early diagnosis of LaCrosse (LAC) virus infections. The MAC-EIA was a sensitive and specific technique for the detection of IgM antibodies to LAC virus in cerebrospinal fluid specimens and in acute-phase serum specimens. In a retrospective study, cerebrospinal fluid and acute-phase serum pair...
BACKGROUND The optimum treatment for high-risk soft-tissue sarcoma (STS) in adults is unclear. Regional hyperthermia concentrates the action of chemotherapy within the heated tumour region. Phase 2 studies have shown that chemotherapy with regional hyperthermia improves local control compared with chemotherapy alone. We designed a parallel-group randomised controlled trial to assess the safety ...
OBJECTIVE In 1998, the Brazilian Ministry of Health made it mandatory for all blood banks in the country to screen donated blood for human immunodeficiency virus (HIV) concomitantly using two different enzyme immunoassay (EIA) tests. Concerned with the best use of available resources, our objective with this study was to evaluate the usefulness of conducting two EIA screening tests instead of j...
In a recent article, Bas and collaborators compared different serological methods to detect chlamydial antibodies in patients with Chlamydia trachomatis infections and healthy blood donors (1). Using the Labsystems enzyme immunoassay (EIA) for C. pneumoniae, no cross-reaction between C. trachomatis and C. pneumoniae was found. However, Gnarpe and collaborators recently showed cross-reactions be...
