Purple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with trypto...
In 1990 an outbreak of contagious bovine pleuropneumonia (CBPP) occurred in Italy. Subsequent surveillance for CBPP was based on random sampling in bovine herds, serological controls on all animals moved from the herd of origin and controls on slaughtered animals. Official tests employed were the complement fixation test (CFT) and bacteriological isolation and typing. A total of 33,856 serum sa...
Groundwater within Area 3 of the U.S. Department of Energy (DOE) Environmental Remediation Sciences Program (ERSP) Field Research Center at Oak Ridge, TN (ORFRC) contains up to 135 microM uranium as U(VI). Through a series of experiments at a pilot scale test facility, we explored the lower limits of groundwater U(VI) that can be achieved by in-situ biostimulation and the effects of dissolved o...
BACKGROUND Epidemiological investigations of recent outbreaks of vaccine preventable diseases have indicated that incomplete immunization was the major reason for the outbreaks. In Ethiopia, full immunization rate is low and reasons for defaulting from immunization are not studied well. The objective of the study was to identify the predictors of defaulting from completion of child immunization...
This is a non-refereed presentation that examines the use of quadrature bandpass sampling (QBPS), reviewing several of the results recently presented in [1]. Like bandpass sampling (BPS), this technique allows signals with a high frequency carrier to be sampled at a rate not less than twice the signal bandwidth. The actual available frequencies for sampling are shown to many more than for bandp...
The recent outbreak of Q fever in The Netherlands warned European health authorities of the need of studying Coxiella burnetii. In Portugal, little is known about C. burnetii infection in animals. A cross-sectional study was designed to investigate the exposure to C. burnetii in sheep and goats in the Central region of Portugal, estimating the herd and individual prevalence. A serosurvey was co...
Objective: To assess the performance of diverse prenatal diagnostic approaches for nuchal translucency (NT) thickening and to investigate optimal screening or action with a NT 95th percentile-3.50 mm. Methods: A retrospective analysis 2,328 pregnancies ≥ percentile through ultrasound-guided transabdominal chorionic villus sampling (CVS), amniocentesis, cordocentesis obtained clinical samples (c...
BACKGROUND All sonomarkers used to screen for fetal hemoglobin (Hb) Bart's disease need high expertise, preventing them from being widely used. Fetal cardiac diameter to biparietal diameter (C/B) ratio is a simple marker which has never been evaluated for its effectiveness. Therefore, we conducted this study to evaluate the effectiveness of C/B ratio in predicting fetal Hb Bart's disease among ...
Objective The objective of this study was to review the management strategies and outcomes in gravidas with anti-M alloimmunization over 15 years. Study Design Data collected from 195 pregnant patients with anti-M antibodies from July 2000 through June 2016 were reviewed retrospectively. We analyzed indirect antiglobulin test titer results, paternal or fetal/neonatal M antigen status, antepar...
Our purpose was to develop and evaluate isolation and enrichment of fetal erythroblasts and a nested polymerase chain reaction (PCR) approach using fetal erythroblasts for detecting the beta-globin gene mutations for a noninvasive prenatal diagnosis of hemoglobinopathies. Maternal blood at different periods of gestation was layered on a Percoll density gradient for enrichment of fetal nucleated...
