Urinary Schistosomiasis in two family populations, using school children as tracers
(1988)Two groups of families designated A and B were studied for Schistosoma haematobium infection in Amagunze, Anambra State, Nigeria. The groups were selected on the basis of a preliminary screening of schoolchildren: group A ... -
Urinary soluble egg antigen levels in Schistosoma haematobium infection in relation to sex and age of Kenyan schoolchildren following praziquantel treatment
(2009-08)Schistosoma haematobium soluble egg antigen (SEA) secreted in urine can be assayed to determine egg tissue load and hence morbidity in infected individuals. A cohort of 158 infected children aged 4-18 years was followed-up ... -
Use of human nails as bio-indicators of heavy metals environmental exposure among school age children in Kenya
(2008-04)Metal pollution and its health effects present a challenge currently facing the developing countries. Metal poisoning is usually difficult and expensive to assess or screen in these countries due to limited resources, ... -
Value chain and sustainability of mangrove wood harvesting in Lamu, Kenya

Variation and Association of Cup Quality Attributes and Resistance to Coffee Berry Disease in Coffea Arabica L. Composite Cultivar, Ruiru 11
(2013-12)Majority of reported work on coffee breeding primarily concerns agronomic improvement that directly impinges on coffee quality. However, it is crucial that coffee breeding programmes for disease resistance also include ... -
Variation in Seagrass Carbon Stocks Between Tropical Estuarine and Marine Mangrove-Fringed Creeks
(Frontiers in Marine Science, 2020-08)Seagrass and associated blue carbon ecosystems are important carbon sinks, and hence understanding their spatial and temporal variability is vital in appreciating their potential roles in climate change mitigation and ... -
Vertical Distribution of Plant-Parasitic Nematodes in Sweet Potato
(Sciendo., 2022)Plant-parasitic nematodes (PPN) are harmful pests that have become a severe threat to crop production worldwide. Diversity of PPN at horizontal and spatial scales influence the effectiveness of control strategies. This ... -
