Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions
(2017-02)Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. ... -
Nephrotoxicity effects of Khat (Catha edulis) on mice when administered orally
(2017-03)Renal problems are currently on increase worldwide. Some factors suspected to be the cause of the renal problems are drug abuse. Hence, this study investigated possible renal toxicity effect of ... -
On Analytical Approach to Semi-open/Semi-closed sets in Metric Spaces”
(Science Publishing Group, 2017-03-03)The concept of open and closed sets has been extensively discussed on both metric and topological spaces. Various properties of these sets have been proved under the underlying spaces. However, scanty literature is available ... -
Potential of native rhizobia in enhancing nitrogen fixation and yields of climbing beans (Phaseolus vulgaris L.) in Contrasting Environments of Eastern Kenya
(2017-03-13)Climbing bean (Phaseolus vulgaris L.) production in Kenya is greatly undermined by low soil fertility, especially in agriculturally prolific areas. The use of effective native rhizobia inoculants to promote nitrogen fixation ... -
Modifying Surber sampling technique increases capture of freshwater crabs in African upland streams. Inland Waters. 2:11-15
(2017-04-03)We compared 2 methods for sampling the freshwater crab Potamonautes odhneri (Colosi) in Kenyan streams: standard Surber sampling, in which a sample is taken over a period of several minutes; and rapid Surber sampling, ... -
Phytochemical screening and antipyretic activities of dichloromethanemethanolic leaf and stem bark extracts of Ximenia americana in rat models
(2017-07)Introduction: In most parts of Africa, Ximenia americana is used in folklore to treat various disorders such as oedema, pain, fever, helminthiasis, diarrhoea, burns among other diseases. This study tested the antipyretic ... -
