Growth and Gas Exchange Responses of Maize and Banana Plants in an Intercrop with Agroforestry Tree Species in Vihiga County, Kenya
(Asian Journal of Research in Crop Science, 2021)Agroforestry trees have been reported to improve soil fertility through nitrogen fixation, coupled with leaves and twig decomposition. High human population pressure in Vihiga County has led to reduced land area under ... -
Measurement of improvement achieved by participation in international laboratory accreditation in sub-Saharan Africa: the Aga Khan University Hospital Nairobi experience
(Oxford University Press, 2014)As part of the ISO 15189:2007 accreditation process, the Aga Khan University Hospital Nairobi laboratory became the first internationally accredited hospital laboratory in sub-Saharan Africa outside South Africa in 2011 ... -
Family history as a risk for early-onset type 2 diabetes in Kenyan patients.
(African Journal of Diabetes Medicine 15, 2014)Early-onset type 2 diabetes is regarded as disease occurring before the age of 40 years. It is well described, and increasing in prevalence, but there is little information from Africa. We therefore assessed the prevalence of ... -
Comparison of equations for estimating glomerular filtration rate in screening for chronic kidney disease in asymptomatic black Africans: a cross sectional study
(BioMed Central, 2017)Several equations have been developed to estimate glomerular filtration rate (eGFR). The common equations used were derived from populations predominantly comprised of Caucasians with chronic kidney disease (CKD). Some ... -
Metabolic syndrome and its predictors in an urban population in Kenya: a cross sectional study
(BioMed Central, 2017)The metabolic syndrome (MetS) is a clustering of interrelated risk factors which doubles the risk of cardio-vascular disease (CVD) in 5–10 years and increases the risk of type 2 diabetes 5 fold. The identification ... -
Complete blood count reference intervals from a healthy adult urban population in Kenya
(Public Library of Science, 2018)There are racial, ethnic and geographical differences in complete blood count (CBC) reference intervals (RIs) and therefore it is necessary to establish RIs that are population specific. Several studies have been carried ... -
Vitamin D status in healthy black African adults at a tertiary hospital in Nairobi, Kenya: a cross sectional study
(BioMed Central, 2018)Vitamin D has been known since the twentieth Century for its benefits in bone health. Recent observational studies have demonstrated its benefits in infectious diseases such as tuberculosis and non-communicable diseases ... -
Determination of reference intervals for common chemistry and immunoassay tests for Kenyan adults based on an internationally harmonized protocol and up-to-date statistical methods
(Public Library of Science, 2020)Due to a lack of reliable reference intervals (RIs) for Kenya, we set out to determine RIs for 40 common chemistry and immunoassay tests as part of the IFCC global RI project. -
Fasciola gigantica: Comparison of the tegumental ultrastructure in newly excysted metacercariae and in vitro penetrated juvenile flukes indicates intracellular sources of molecules with vaccinal and immunomodulatory potential
(Elsevier, 2019)Using in vitro procedures to prepare newly excysted metacercariae and gut-penetrated juvenile Fasciola gigantica, the ultrastructural features of the tegumental syncytium and perikarya of these ephemeral stages in the ... -
Effect of Implementation of Free Maternity Policy on Selected Maternal and Newborn Health Indicators in Gem Sub-County, Siaya County, Western Kenya
(Johns Hopkins University Press, 2019)Introduction. Kenya introduced free maternity services in June 2013. The main study objective was to investigate the effect of this intervention on maternal and newborn health and specifically to determine differences ... -
Comparison of GeneXpert and line probe assay for detection of Mycobacterium tuberculosis and rifampicin-mono resistance at the National Tuberculosis Reference Laboratory, Kenya
(BMC infectious disease, 2019)The dual challenge of low diagnostic sensitivity of microscopy test and technical challenge of performing a TB culture test poses a problem for case detection and initiation of Tuberculosis (TB) second-line treatment. ... -
Correlation Between Malaria-Specific Antibody Profiles and Responses to Artemisinin Combination Therapy for Treatment of Uncomplicated Malaria in Western Kenya
(Oxford University Press, 2019)The impact of preexisting immunity on the efficacy of artemisinin combination therapy must be examined to monitor resistance, and for implementation of new treatment strategies -
A cross-sectional observational study investigating the association between sedges (swamp grasses, Cyperaceae) and the prevalence of immature malaria vectors in aquatic habitats along the shore of Lake Victoria, western Kenya
(Faculty of 1000 Ltd, 2020)Strategies that involve manipulations of the odour-orientation of gravid malaria vectors could lead to novel attract-and-kill interventions. Recent work has highlighted the potential involvement of graminoid plants in ... -
Direct and indirect efects of predation and parasitism on the Anopheles gambiae mosquito
(Parasites & Vectors, 2020)A good understanding of mosquito ecology is imperative for integrated vector control of malaria. In breeding sites, Anopheles larvae are concurrently exposed to predators and parasites. However, to our knowledge, there ... -
Fasciola gigantica: ultrastructural cytochemistry of the tegumental surface in newly-excysted metacercariae and in vitro-penetrated juvenile flukes informs a concept of parasite defence at the interface with the host
(Elsevier, 2019)Cytochemical staining techniques were carried out en bloc with in vitro excysted and gut-penetrated Fasciola gigantica larvae in order to visualise the glycocalyx of the tegument, a structure which comprises the parasite ... -
Uptake of conventional interventions, level of awareness and perception on computer vision syndrome: a cross-sectional study among University students, Kenya
(Ophthalmol J, 2021)Awareness and perception are critical determinants in the uptake of a health intervention. This study assessed the level of awareness and perception in relation to the uptake of interventions of computer vision syndrome (CVS) ... -
GROWTH RATE OF AFRICAN CATFISH (Clarias gariepinus) AND PLANKTON DIVERSITY IN PONDS UNDER ORGANIC AND INORGANIC FERTILIZATION
(African journal of food agriculture nutrition and development, 2021)Aquaculture offers the opportunity for safeguarding local and global food security in the face of declining capture fisheries. However, the form of aquaculture that is commonly practised in Kenya is characterized by the ... -
Grass-Like Plants Release General Volatile Cues Attractive for Gravid Anopheles Gambiae S.S. Malaria Vector Mosquitoes
(Research square, 2021)Understanding the ecology and behaviour of disease vectors, including the olfactory cues used to orient and select hosts and egg-laying sites, are essential for the development of novel, insecticide-free control tools. ... -
