Differential Induction of Proteins in Anopheles gambiae sensu stricto (Diptera: Cullicidae) Larvae in Response to Heavy Metal Selection
(Cambridge University Press, 2006)Investigations were conducted to establish the magnitude and pattern of differential expression of proteins due to generational selection of third instar An. gambiae s.s. larvae by cadmium, copper and lead heavy metals, ... -
Distribution of indigenous strains of atoxigenic and toxigenic Aspergillus flavus and Aspergillus parasiticus in maize and peanuts agro-ecological zones of Kenya
(BioMed Central, 2015)Background Grains of important food and export crops in Africa are susceptible to contamination by toxin-producing moulds. Aflatoxins are mycotoxins associated with liver damage and cancer in humans and animals. These ... -
Diversity of fungi in sediments and water sampled from the hot springs of Lake Magadi and Little Magadi in Kenya
(African Journal of Microbiology Research, 2016-03-14)Lake Magadi and Little Magadi are saline, alkaline lakes lying in the southern part of Kenyan Rift Valley. Their solutes are supplied by a series of alkaline hot springs with temperatures as high as 86°C. Previous ... -
Dual African Origins of Global Aedes aegypti s.l. Populations Revealed by Mitochondrial DNA
(Public Library of Science, 2013)Background: Aedes aegypti is the primary global vector to humans of yellow fever and dengue flaviviruses. Over the past 50 years, many population genetic studies have documented large genetic differences among global ... -

(Chemical Science International Journal, 2018-05)Aims: The effect of Rhizoclonium grande saturated fatty acid ethyl esters on physicochemical and fuel properties of Jatropha curcas biofuel was assessed. Study Design: Probability and purposeful sampling methods were ... -
Effects of DCM Leaf Extract of Gnidia glauca (Fresen) on Locomotor Activity, Anxiety, and Exploration-Like Behaviors in High-Fat Diet-Induced Obese Rats
(Hindawi, 2019)Obesity is the main component of metabolic syndromes involving distinct etiologies that target different underlying behavioral and physiological functions within the brain structures and neuronal circuits. An alteration ... -
The epidemiology of tuberculosis in Kenya, a high TB/HIV burden country (2000-2013)
(International Journal of Public Health and Epidemiology Research, 2015)Interest in the epidemiology of TB was triggered by the re-emergence of tuberculosis in the early 1990’s with the advent of HIV and falling economic status of many people which subjected them to poverty. The dual lethal ... -
Expression of metallothionein and α-tubulin in heavy metaltolerant Anopheles gambiae sensu stricto (Diptera: Culicidae)
(Academic Press, 2010)Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats. In this study we explored the possibility of using Anopheles gambiae sensu stricto as bio-reporters for environmental heavy metal ... -
Genetic susceptibility to endomyocardial fibrosis
(2014)Background: Endomyocardial fibrosis (EMF) is the most common form of restrictive cardiomyopathy worldwide. It has been linked to poverty and various environmental factors, but—for unknown reasons—only some people who ... -
Genome-wide association mapping revealed a diverse genetic basis of seed dormancy across subpopulations in rice (Oryza sativa L.)
(BioMed Central, 2016-01-21)Seed dormancy is an adaptive trait employed by flowering plants to avoid harsh environmental conditions for the continuity of their next generations. In cereal crops, moderate seed dormancy could help prevent pre-harvest ... -
Genomewide association analysis for awn length linked to the seed shattering gene qSH1 in rice
(Indian Academy of Sciences, 2016-09)Awn is one of the most important domesticated traits in rice (Oryza sativa). Understanding the genetic basis of awn length is important for grain harvest and production, because long awn length is disadvantageous for both ... -
Homeobox Is Pivotal for OsWUS Controlling Tiller Development and Female Fertility in Rice
(G3: Genes, Genomes, Genetics, 2016-05-17)OsWUS has recently been shown to be a transcription factor gene critical for tiller development and fertility in rice. The OsWUS protein consists of three conserved structural domains, but their biological functions are ... -
Hypoglycemic effect of Helichrysum odoratissimum in alloxan induced diabetic mice
(The Journal of Phytopharmacology, 2015)Diabetes mellitus is a disease of antiquity with worrying global incidence and prevalence. Conventional management and/or treatment interventions have been hampered by drawbacks like high costs, inaccessibility, likelihood ... -
HYPOGLYCEMIC EFFECTS OF CAESALPINIA VOLKENSII ON ALLOXAN-INDUCED DIABETIC MICE
(Asian Journal of Pharmaceutical and Clinical Research, 2012)Diabetes mellitus is a chronic disorder caused by inherited and/or acquired deficiency in production of insulin by the pancreas or by the ineffectiveness of the insulin produced by the target cells. Most conventional ... -
Impact of Marine Woodborers Dicyathifer mannii, Sphaeroma terebrans and Cirolana sp. on the Mangroves of the Kenyan Coast
(International Journal of Ecology and Environmental Sciences, 2015)Three species of woodborers from marine mangrove plants at Mida Creek, Tudor Creek and Gazi Bay along the Kenyan coast are identified. The relationship between the borers and the host mangrove plants (Avicennia, Sonneratia, ... -
