Evidence for the involvement of a tsetse midgut lectin-trypsin complex in differentiation of bloodstream-form trypanosomes
(University of NairobiCollege of biological and physical science, 2003)We have previously described a bloodmeal-induced molecule (lectin-trypsin complex) from the midgut of the tsetse fly, Glossina longipennis, with both lectin and trypsin activities (Osir et al., 1995). In this paper, we ... -
Late Quaternary glacial-interglacial cycle of climatic and environmental change on Mount Kenya, Kenya
(University of NairobiDepartment of Geology, 1999-10)Sediments from Sacred Lake and Lake Nkunga on the northeastern flank of Mount Kenya have a sequential palaeoclimatic and palæoenvironmental record covering most of the Late Quaternary period: from ca 115 to 0 ka. Most of ... -

Late Quaternary primary tephras in Sacred Lake sediments, northeast Mount Kenya, Kenya
(University of NairobiDepartment of Geology, 2000-05)In this paper, a sequence of five Late Quaternary tephras occurring as discrete, well-preserved horizons in lake sediments on the northeastern flank of Mount Kenya are characterised and their ages determined by a combination ... -

Comparison of GPS TEC variations with IRI-2007 TEC prediction at equatorial latitudes during a low solar activity (2009–2011) phase over the Kenyan region
(University of NairobiDepartment of Physics, 2012)This work presents an analysis of the Total Electron Content (TEC) derived from the International GNSS Service (IGS) receivers at Malindi (mal2: 2.9oS, 40.1oE, dip −26.813o), Kasarani (rcmn: 36.89oE, 1.2oS, dip −23.970o), ... -
Responses of Acacia tortilis and Acacia xanthophloea to seasonal changes in soil water availability in the savanna region of Kenya
(ScienceDirectDepartment of Plant Ecology, University of Bayreuth, P.O. Box 95440, Bayreuth 049, Bavaria, GermanDepartment of Botany, University of Nairobi,, 2005)Comparative field studies were conducted on Acacia tortilis (Forsk.) Hyne and Acacia xanthophloea Benth. trees growing in a semi-arid environment in Kibwezi, Kenya, to assess root access to soil water at varying soil depths ... -
Signal transduction in malaria gametocytes. biochemical pathways in parasites of medical importance
(University of Nairobicollege of biological and physical science, 1998)Cultivated Plasmodium falciparum gametocytes reach maturity in vitro in approximately 14-16 days, during which they pass through five morphologically distinct developmental stages. Purification of the earlier developmental ... -

Proline synthesis in the fat body of the tsetse fly Glossina morsitans, and its stimulation by isocitrate
(University of NairobiDepartment Of Biochemistry, 1988)The in vitro synthesis of proline from glutamate was followed in fat body homogenates from the tsetse fly Glossina morsitans. Rates of synthesis were much higher in freeze-thawed or sonicated homogenate than in untreated ... -
Enzyme activities in flight and leg muscle of the dung beetle in relation to proline metabolism
(University of NairobiDepartment of Biochemistry, 1979)Relatively high activities of NAD-linked ‘malic’ enzyme (E.C.1.1.1.39) and alanine aminotransferase (E.C.2.6.1.2), predominantly or entirely mitochondrial, were found in the flight and coxal muscle of three species of dung ... -
Changes in the contents of intermediates of proline and carbohydrate metabolism in flight muscle of the tsetse fly Glossina morsit ans and the fleshfly Sarcophaga tibialis
(University of NairobiDepartment of Biochemistry, 1982)1. The contents of intermediates of proline metabolism, the tricarboxylate cycle and glycolysis were measured over the initial phases of flight in the thorax of the tsetse fly Glossina morsitans and the fleshfly Sarcophaga ... -

Initial Correlations Among The Levels Of Various Nutrient Species In Water From Nairobi Dam, Kenya
(2011)Research work on Nairobi Dam, Kenya, and its tributaries has revealed that during the first trial sampling period, the R2 value, i.e., the square of linear regression correlation coefficient was poor between the nutrients: ... -

Regional setting and nature of gold mineralization in Tanzania and southwest Kenya
(University of NairobiDepartment of Geology, 1990-01)The most productive gold deposits in Tanzania and southwest Kenya are in the Nyanzian greenstone belts (2700 Ma) and the Ubendian System (2000 Ma). The deposits occur in the form of massive or disseminated Fe-sulphide-rich ... -
Enzyme activities in the fat body of the tsetse fly Glossina morsitans and the fleshfly Sarcophaga tibialis in relation to proline metabolism
(University of NairobiDepartment of Biochemistry, 1984)Enzymes were assayed in the fat body of the tsetse fly Glossina morsitans and compared with those in the fat body of the fleshfly Sarcophaga tibialis. Alanine aminotransferase, 3-hydroxyacyl-CoA dehydrogenase, NADP-linked ... -
Using GPS-SCINDA observations to study the correlation between scintillation, total electron content enhancement and depletions over the Kenyan region
(University of NairobiDepartment of Physics, 2012-05)This paper presents the first results of total electron content (TEC) depletions and enhancement associated with ionospheric irregularities in the low latitude region over Kenya. At the low latitude ionosphere the diurnal ... -
