The Groundnut Department at National Semi-Arid Research Resources Institute (NaSARRI) is mandated to conduct research on groundnuts (Arachis hypogaea L) in Uganda. It undertakes research aimed at cultivar development, maintenance and conservation through germplasm collection, characterization, evaluation, breeding, maintenance and generation of appropriate(More)
Serum samples from Ugandan residents of a malaria-hyperendemic region were tested by enzyme-linked immunosorbent assay for reactivity against recombinant constructs of the 47 (SE47')- and 50 (SE50A)-kDa fragments of Plasmodium falciparum serine repeat antigen (SERA). Immunoglobulin (Ig) G3 and IgG1 were the predominant subclass responses to SE47' and SE50A,(More)
During development, limb-bud mesenchymal cells carry out complex spatiotemporal-patterns of growth and differentiation. Tissue and organ culture facilitate analysis of environmental influences on these cell behaviors, allowing their partial dissection into exogenous and endogenous components. Two factors that complicate such in vitro analyses are the(More)
OBJECTIVE To determine the natural human humoral immune responses to the 19 kilodalton carboxy terminal fragment of Plasmodium falciparum merozoite surface protein 1 (MSP1(19)), a malaria candidate vaccine antigen and to determine the prevalence of MAD20 and K1 alleles of P. falciparum MSP1. DESIGN Community based cross-sectional study. SETTING Atopi(More)
BACKGROUND There are concerns that the evidence from studies showing noninferiority of oral amoxicillin to benzyl penicillin for severe pneumonia may not be generalizable to high-mortality settings. METHODS An open-label, multicenter, randomized controlled noninferiority trial was conducted at 6 Kenyan hospitals. Eligible children aged 2-59 months were(More)
A cross-sectional survey was conducted in neonatal and maternity units of five Kenyan district public hospitals. Data for 1 year were obtained: 3999 maternal and 1836 neonatal records plus tallies of maternal deaths, deliveries and stillbirths. There were 40 maternal deaths [maternal mortality ratio: 276 per 100 000 live births, 95% confidence interval(More)
OBJECTIVE To establish Plasmodium falciparum malariometric indices in a field study site in Apac district, northern Uganda. DESIGN A community-based cross sectional survey. SETTINGS Atopi Parish, Apac district, Uganda, 1995. SUBJECTS One thousand two hundred and thirty four volunteers aged below one and ninety years. MAIN OUTCOME MEASURES P.(More)
In recent years, proliferation of wireless devices has increased wireless access to nearly all of the world's population and use of services like mobile systems, GPS and Wi-Fi. Users are mobile, dynamic and majority prefer the 30MHz - 3000MHz band of the 300GHz spectrum due to propagation and equipment feasibility, rendering spectrum finite and constrained(More)
Retinoic acid (RA) has been shown to affect skeletal patterning in vivo in both developing and regenerating limbs. Regional differences in RA concentrations alone cannot account for the region-specific cell behaviors involved in limb-skeletal morphogenesis. The present study explores a role for regional differences in signal interpretation in RA's effects(More)
