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 ... -
Recent limnological changes and their implication on fisheries in Lake Baringo, Kenya
(Academic Journals, 2014)Water samples for physico-chemical analysis for this study were collected monthly for five years between April 2008 and March 2013. Conductivity, temperature, dissolved oxygen and pH was measured in situ using a Surveyor ... -
Spatial variations in nutrients and other physicochemical variables in the topographically closed Lake Baringo freshwater basin (Kenya)
(Lakes & Reservoirs: Research & Management, 2014)Spatial physicochemical parameters were determined from 39 sampling sites distributed throughout Lake Baringo during December 2010. Mean values of temperature, dissolved oxygen concentration and electrical conductivity ... -
Rapid detection of carbapenemase-producing Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae using a bioluminescence-based phenotypic...
(Elsevier, 2014-04-01)Accurate detection of carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing carbapenem-resistant Acinetobacter spp. (CP-CRA) constitutes a major challenge in laboratory diagnostics. We developed a ... -
Efficacy of synergized and non-synergized Tagetes minuta methanol extract in controlling Periplaneta americana within households
(Malhotra Publishing House, 2015)In this study, comparative analysis of Sesamum indicum L. oil synergized and non-synergized methanol extract of the T. minuta were assayed against P. americana collected from households within Maseno Division, Kenya. The ... -
Occupational Health and Safety Administration (OSHA) in the Morgues: Management and practice of the universal precautions in Morgues in Kenya
(Biosafety, 2015)Morgues provide a risky work environment that requires universal safety precaution since it presents a variety of Occupational Health and Safety (OHS) challenges. Although OHS is a top priority internationally, in ... -
Epstein–Barr Virus Genetic Variation in Lymphoblastoid Cell Lines Derived from Kenyan Pediatric Population
(Public Library of Science, 2015)Epstein-Barr virus (EBV) is associated with Burkitt’s lymphoma (BL), and in regions of sub-Saharan Africa where endemic BL is common, both the EBV Type 1 (EBV-1) and EBV Type 2 strains (EBV-2) are found. Little is known ... -
Antimicrobial activities of microorganisms obtained from the gut of Macrotermes michaelseni in Maseno, Kenya
(Journal of Applied Biology and Biotechnology, 2015-11)The gut of termites is a major source of termicin and spinigerin antibiotics. The termite gut thus presents a novel habitat for searching new antibiotic producing isolates. The objective of this study was to investigate ... -
