Selenium deficiency risk in central Kenya highlands: an assessment from the soil to the body
(Springer, 2020)Selenium (Se) deficiency is associated with increased risk of clinical disorders. Yet, it has not been considered as an important public health issue in Africa. The health burden of this ‘hidden hunger’ remains largely ... -
Extension of Shelf-life by Limited Duration of Propylene and 1-MCP Treatments in Three Kiwifruit Cultivars
(The Japanese Society for Horticultural Science, 2016)In order to extend the “eating window”, the optimum ripening phase suitable for eating, the combination of treatment with propylene (an ethylene analog) and 1-methylcyclopropene (1-MCP; an ethylene inhibitor) was assessed ... -
Screening of Warburgia Ugandensis Crude Extracts Obtained from Different Organic Solvents against Tomato Phytophthora Infestans and Alternaria Solani
(European International Research, 2019)Alternaria solani and Phytophthora infestans are causative agents of early and late blight of tomatoes respectively which are currently controlled using fungicides. Overuse of fungicides poses safety concerns. The research ... -
Use of heat units to predict the optimum transplanting stage of baby corn (Zea mays L.) seedlings under field conditions in Meru County – Kenya
(International Journal Publishing House, 2019)Baby corn (Zea mays L.) is a type of maize belonging to the Poaceae family of plants. It is grown as a vegetable in a wide range of Agro-ecological zones in Kenya. The plant is mainly grown for its immature unfertilized ... -
Proinflammatory cytokine expression in the early phase of Trypanosoma brucei rhodesiense infection in vervet monkeys (Cercopithecus aethiops)
(2004)A vervet monkey model of trypanosomiasis was used to study inflammatory cytokine responses in serum and cerebrospinal fuid (CSF). Gamma interferon levels were transiently up-regulated in serum between days 6 and 8 of ... -
Influence of cyclophosphamide on the haematological profile of laboratory bred African soft-furred rats (Mastomys natalensis)
(2005)The African soft-furred rat (Mastomys natalensis) has been shown to be a possible model for propagation of Trypanosoma brucei gambiense. This study aimed at determining the baseline biological reference values and reproductive ... -
Lymphosarcoma in Adult African Green Monkeys (Chlorocebus Aethiops)
(Journal of Laboratory Animal Scienc, 2007)The clinical observations and pathological manifestations of lymphosarcoma in two African green monkeys are described. Monkeys had been caught from the wild. Prior to the development of neoplasms one monkey had been ... -
Development of a rodent model for late stage rhodesian sleeping sickness
(National Research Center for Protozoan Diseases, 2007)A mouse model of Trypanosoma brucei rhodesiense that can be used in pathogenesis and drug studies for Human African Trypanosomosis (HAT) has so far not been developed. In an attempt to develop such a model, a study was ... -
Hematological changes in vervet monkeys (Chlorocebus aethiops) during eight months' adaptation to captivity
(American Journal of Primatology, 2007)This study investigated fluctuations in hematological values of 50 wild-caught vervet monkeys (African green monkeys, grivets, Chlorocebus aethiops) during habituation to captivity. The monkeys were categorized into four ... -
Haematology of experimental Trypanosoma brucei rhodesiense infection in vervet monkeys
(African Journal of Health Sciences,, 2006)Haematological aberrations associated with human infective trypanosomes were investigated in the vervet monkey model of the Rhodesian sleeping sickness. Four monkeys were infected intravenously with 104 Trypanosoma brucei ... -
Trypanosoma brucei rhodesiense transmitted by a single tsetse fly bite in vervet monkeys as a model of Human African Trypanosomiasis.
(PLOS, 2008)We have investigated the pathogenicity of tsetse (Glossina pallidipes)-transmitted cloned strains of Trypanosoma brucei rhodesiense in vervet monkeys. Tsetse flies were confirmed to have mature trypanosome infections by ... -
Efficacy of the novel diamidine compound 2,5-Bis(4-amidinophenyl)- furan-bis-O-Methlylamidoxime (Pafuramidine, DB289) against Trypanosoma brucei rhodesiense infection in vervet monkeys after oral administration
(American Society for Microbiology, 2009)10 to 30 days to facilitate treatment with parenterally administered medicines. The efficacy of a novel orally administered prodrug, 2,5-bis(4-amidinophenyl)-furan-bis-O-methlylamidoxime (pafuramidine, DB289), was tested ... -
Efficacy of the diamidine DB75 and its prodrug DB289, against murine models of human African trypanosomiasis
(Elsevier, 2008)The choice of drugs for the treatment of sleeping sickness is extremely limited. To redress this situation, the recently synthesised diamidine, 2,5-bis(4-amidinophenyl)-furan (DB75, furamidine) and its methamidoxime prodrug, ... -
Diamidines for human African trypanosomiasis
(Thomson Reuters, 2010)Aromatic diamidines are potent trypanocides. Pentamidine, a diamidine, has been used for more than 60 years to treat human African trypanosomiasis (HAT); however, the drug must be administered parenterally and is active ... -
