Genetic and Toxigenic Variability within Aspergillus flavus Population Isolated from Maize in Two Diverse Environments in Kenya.
(University of Nairobi, 2018)
Aspergillus flavus is the main producer of carcinogenic aflatoxins in agricultural commodities such as maize. This fungus occurs naturally on crops, and produces aflatoxins when environmental conditions are favorable. The ...
Cytotoxic benzylbenzofuran derivatives from Dorstenia kameruniana
(University of Nairobi, 2018)
Chromatographic separation of the extract of the roots of Dorstenia kameruniana (family Moraceae) led to the isolation of three new benzylbenzofuran derivatives, 2-(p-hydroxybenzyl)benzofuran-6-ol (1), 2-(p-hydroxybenzyl ...
Detection of counterfeit brand spirits using 1H NMR fingerprints in comparison to sensory analysis.
(University of Nairobi, 2018)
Beverage fraud involving counterfeiting of brand spirits is an increasing problem not only due to deception of the consumer but also because it poses health risks e.g. from possible methanol admixture. Suspicious spirit ...
Sequential extraction as novel approach to compare 12 medicinal plants from Kenya regarding their potential to release Chromium, Manganese, Copper, and Zinc.
(University of Nairobi, 2018)
This study is focusing on a novel approach to screen a large number of medicinal plants from Kenya regarding their contents and availability of selected metals potentially relevant for treatment of diabetes patients. For ...
Short proline-rich lipopeptide potentiates minocycline and rifampin against multidrug- and extensively drug-resistant pseudomonas aeruginosa.
(University of Nairobi, 2018)
A series of 16 short proline-rich lipopeptides (SPRLPs) were constructed to mimic longer naturally existing proline-rich antimicrobial peptides. Antibacterial assessment revealed that lipopeptides containing hexadecanoic ...
Mapping potential Anopheles gambiae s.l. larval distribution using remotely sensed climatic and environmental variables in Baringo, Kenya.
(University of Nairobi, 2018)
Anopheles gambiae s.l. (Diptera: Culicidae) is responsible for the transmission of the devastating Plasmodium falciparum (Haemosporida: Plasmodiidae) strain of malaria in Africa. This study investigated the relationship ...
LIBS development methodology for forensic nuclear materials analysis
(University of Nairobi, 2018)
Nuclear forensics (NF) is an important tool for the analysis of intercepted nuclear and radiological materials (NRM) to establish the relationship between NRM and their attribution in support of nuclear security. The ...
Soil contamination from lead battery manufacturing and recycling in seven African countries.
(University of Nairobi, 2018-02)
Lead battery recycling is a growing hazardous industry throughout Africa. We investigated potential soil contamination inside and outside formal sector recycling plants in seven countries. We collected 118 soil samples at ...
Cytotoxic flavonoids from two Lonchocarpus species.
(University of Nairobi, 2018)
A new isoflavone, 4'-prenyloxyvigvexin A (1) and a new pterocarpan, (6aR,11aR)-3,8-dimethoxybitucarpin B (2) were isolated from the leaves of Lonchocarpus bussei and the stem bark of Lonchocarpus eriocalyx, respectively. ...
Discovery of a novel species, Theileria haneyi n. sp., infective to equids, highlights exceptional genomic diversity within the genus Theileria: implications for apicomplexan parasite surveillance.
(University of Nairobi, 2018)
A novel apicomplexan parasite was serendipitously discovered in horses at the United States - Mexico border. Phylogenetic analysis based on 18S rDNA showed the erythrocyte-infective parasite to be related to, but distinct ...
