The pyridinium cross-links of collagen, pyridinoline (Pyd) and deoxypyridinoline (Dpd), provide structural integrity and rigidity to collagen fibrils in bone. During bone degradation (resorption), the cross-links are released into the circulation and eventually excreted in urine. Pyridinium cross-link measurements in urine have been shown to be sensitive and specific indicators of resorption by...
We compared the performance of a commercial enzyme immunoassay (EIA) (Chlamydiazyme; Abbott Diagnostics, North Chicago, Ill.) with that of cell culture for the detection of Chlamydia trachomatis cervical infection in 1,417 women attending public health clinics. Confirmatory chlamydial testing by a direct fluorescent-antibody test (MicroTrak; Syva Co., Palo Alto, Calif.) was performed on specime...
We compared rotavirus detection rates in children with acute gastroenteritis (AGE) and in healthy controls using enzyme immunoassays (EIAs) and semiquantitative real-time reverse transcription PCR (qRT-PCR). We calculated rotavirus vaccine effectiveness using different laboratory-based case definitions to determine which best identified the proportion of disease that was vaccine preventable. Of...
Lack of attention to the early design process in relation to Environmental Impact Assessment (EIA) has lead to an unsustainable built environment. Often building auditing/monitoring utilising EIA and Life Cycle Cost Assessment (LCCA) tools are used after the completion of the project, when it is too late to influence the design, materials or components to be used. A sub-processes focusing on en...
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...
