We performed a comparative analysis between Roche Amplicor HIV-1 DNA test and CAPTAQ assay for the detection of HIV in 830 dried blood spot (DBS) pediatric samples collected in Mozambique. Our results demonstrated no statistical difference between these assays. The CAPTAQ assay approached nearly 100% repeatability/accuracy. The increased throughput of testing with minimal operator interference ...

The present paper reports evidence of an immunological relationship between one variety or type of the yeast Saccharomyces cerevisi~e and the Type II variety of Diplococcus pn,umoni~e (Pneumococcus). The immunological interrelationships among the different yeasts have never been well established, but it is certain that all of the yeasts included by the species term Saccharomyces cerevisi~ are n...

Traditional newborn dried blood spot screening (NDBS) has expanded in recent years to include upwards of 50 different conditions in many states. Once the screening tests are complete, the residual blood specimens (RBSs) that remain are most often available for quality assurance and public health research. The articles by Botkin et al1 and Bombard et al2 contained in this issue of Pediatrics inv...

A community based cross-sectional study was carried out in rural areas of West Bengal with the aim to assess the prevalence of vitamin A deficiency (VAD) among rural preschool children. Clinical examination was carried out on 9,228 children for the signs and symptoms of VAD and a sub-sample of 590 children were covered for the estimation of blood vitamin A levels using dried blood spot (DBS) me...

BACKGROUND Assays have been developed for cross-sectional HIV incidence estimation using plasma samples. Large scale surveillance programs are planned using dried blood spot (DBS) specimens for incidence assessment. However, limited information exists on the performance of HIV cross-sectional incidence assays using DBS. METHODS The assays evaluated were: Maxim HIV-1 Limiting Antigen Avidity E...

During brewery handling, production strains of yeast must respond to fluctuations in dissolved oxygen concentration, pH, osmolarity, ethanol concentration, nutrient supply and temperature. Fermentation performance of brewing yeast strains is dependent on their ability to adapt to these changes, particularly during batch brewery fermentation which involves the recycling (repitching) of a single ...

PREMISE OF THE STUDY We tested the credibility and significance of digital field photographs as supplements or substitutes for conventional herbarium specimens with particular relevance to exploration of the tropics. METHODS We made 113 collections in triplicate at a species-rich mountain in the Philippines while we took 1238 digital photographs of the same plants. We then identified the plan...

background; various industries produce and discharge wastes containing different heavy metals into the environment. apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. method; the cadmium (cd) (ii) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of aspergillus versicolor were examined as...
