A avaliação de impactos ambientais representa um importante instrumento constitucional da gestão ambiental no Brasil, a partir do qual se tem como objetivo minimizar os negativos empreendimentos considerados potencialmente poluidores. O Estudo Impacto Ambiental (EIA) é o principal estudo utilizado, em processos licenciamento ambiental, para analisar viabilidade atividades ou obras que tenham po...

Electromagnetically induced absorption (EIA) is an optical phenomenon that enhances light of plasmonic systems. Depending on the system under investigation, decisive role intrinsic versus radiative damping and phase retardation has been pointed out to control EIA. Herein, a unified interpretation provided mechanism EIA for plasmonic–dielectric composites all-plasmonic dipolar–quadrupolar antenn...

A new enzyme immunoassay (EIA), PREMIER Cryptococcal Antigen, was compared with latex agglutination (LA) for the detection and quantitation of circulating capsular polysaccharide antigen from Cryptococcus neoformans. The clinical evaluation of PREMIER EIA as a screening assay, including 475 specimens with 120 LA and EIA positives, resulted in 99% sensitivity and 97% specificity. The clinical sp...

BACKGROUND The reported prevalence of exercise induced asthma (EIA) in elite winter athletes ranges from 9% to 50%. Many elite winter athletes do not report symptoms of EIA. At present there is no gold standard test for EIA. OBJECTIVE To establish the efficacy of screening for EIA and examine the role of the eucapnic voluntary hyperventilation (EVH) challenge and laboratory based and sport sp...

BACKGROUND Active vitamin B12 absorption is followed by an increase in holotranscobalamin (holoTC) upon loading with a high physiological dose of the vitamin (the CobaSorb test). This study evaluates the use of a newly launched EIA kit for measurement of holoTC (active B12) in relation to the CobaSorb test. METHODS Intra-assay imprecision and linearity of the EIA kit was examined, employing s...

The value of several serological tests was assessed by studying sera from 30 women with clinical findings of perihepatitis and a high chlamydial antibody titre in the indirect immunofluorescence antibody test (IFAT). The other tests included the complement fixation test and enzyme immunoassays in which the antigen comprised either partially purified particles (EIA kit) or purified major outer m...

A solid-phase enzyme immunoassay (EIA) was developed for the detection of poliovirus antigen. Rabbit and guinea pig antisera for the assay were raised against purified poliovirus type 3/Fin (strain 3/Fin/K) isolated from a fecal specimen from a meningitis patient during an outbreak of poliomyelitis in Finland in 1984. The EIA was highly specific for poliovirus type 3, and it was about 30 times ...

A molecular dissection of the adenovirus EIIA early (E) promoter was undertaken to study the sequence elements required for transcription and to examine the nucleotide sequences, if any, specific for its trans-activation by the viral pre-early EIA gene product. A chimeric gene in which the EIIA-E promoter region fused to the coding sequences of the bacterial chloramphenicol acetyltransferase (C...
