cryptococcus neoformans is the most incriminated fungal pathogen causing meningitis in acquired immune deficiency syndrome (aids) patients, and is known to constitute a major cause of deaths in aids patients. this study aimed to determine the sero-prevalence and effect of cd4 count on seropositivity for cryptococcus neoformans antigen (crag) in antiretroviral- naïve (art-naïve) aids patients. t...

background: citation metrics and total publications in a field has become the gold standard for rating researchers and viability of a field. hence, stimulating demand for citation has led to a search for useful strategies to improve performance metric index. meanwhile, title, abstract and morphologic qualities of the articles attract researchers to scientific publications. yet, there is relativ...

Regarding the continuing debate in EHP over the question ofwhether or not human sperm densities have declined in the United States, I feel compelled to respond to the statement by Swan et al. (1) that regional variation would not be inconsistent with the average decline that we demonstrated in Europe and the United States. In referring to regional variation in sperm densities, Swan et al. cite ...

recently testing of quantum-dot cellular automata (qca) circuits has attracted a lot of attention. in this paper, qca is investigated for testable implementations of reversible logic. to amplify testability in reversible qca circuits, a test method regarding to built in self test technique is developed for detecting all simulated defects. a new reversible qca mux 2×1 design is proposed for the ...
