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 ... -
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 ... -
Polyploidy Breeding of African Nightshade (Solanum section Solanum)
(International Journal of Plant Breeding, 2007)The perception of African nightshades (Solanum section Solanum) as “healthy” foods, supported by documentation of their high nutritional and medicinal benefits, has led to a sudden and steady upsurge in their consumption, ... -
Partial Fertility Restoration as Affected by Night Temperature in a Season-dependent Male-sterile Mutant Tomato, Lycopersicon esculentum Mill.
(Journal of the Japanese Society for Horticultural Science, 2007-03-13)This study was conducted to investigate the influence of night temperature on the restoration of fertility in a season-dependent male-sterile tomato mutant (T-4). Plants were grown in greenhouses, in which minimum and ... -
Floral Genetics of African Nightshade (Solanum section Solanum)
(International Journal of Plant Developmental Biology, 2007-04-09)Solanum section Solanum, centering on the species commonly known as African nightshade, and botanically known as the “Solanum nigrum complex” is composed of a large number of morphogenetically distinct taxa, with certain ... -
Scaling up Production of Traditional Green Leafy Vegetables in Kenya: Perspectives on Water and Nitrogen Management
(Dynamic Soil, Dynamic Plant, 2007-08-25)Traditional green leafy vegetables are promising alternative vegetable crops consumed in Kenya and other African countries. The crops whose consumption is on the increase include vegetable amaranth (Amaranthus spp.), African ... -
Somatic embryogenesis and plant regeneration from immature embryos of tropical maize (Zea mays L.) inbred lines
(2008)Somatic embryogenesis and plant regeneration was achieved from immature embryos of six maize (Zea mays L.) inbred lines (CML216, CML78, CML331, TL18, TL27 and MU25). Callus was initiated on N6 medium supplemented with ... -
Microwave Expansion of Imitation Cheese Containing Resistant Starch
(Elsevier, 2008)The objective of this study was to manufacture an imitation cheese that expands to a crispy product when heated in a microwave oven. Imitation cheese (∼18% w/w protein and 60% w/w moisture content) was formulated with ... -
Effects of Refrigerated Storage on Water Mobility and Microwave Expansion of Imitation Cheese containing Resistant Starch
(Elsevier, 2008)The effects of storage time prior to microwave heating on expansion of imitation cheese containing functional fibre was studied. Cheese was formulated to contain 60% moisture and 17.3% w/w resistant starch. Cheese samples ... -
Impact of the invader Ipomoea hildebrandtii on grass biomass, nitrogen mineralisation and determinants of its seedling establishment in Kajiado, Kenya
(African Journal of Range and Forage Science, 2008)The invasive coloniser Ipomoea hildebrandtii aggravates the problem of inadequate grass forage in Kajiado district, Kenya. To test its impact on grass biomass, nitrogen (N) mineralisation and seedling establishment, grazing ... -
Traditional strategies used by pastoralists to cope with la nina induced drought in Kajiado, Kenya
(African Journal of Science and Technology, 2008)Pastoralists traditionally relied on herd mobility to cope with drought. In the pastoral areas of Kajiado, Kenya this strategy is now threatened by increased individual land ownership as compared to communal access. Drought ... -
