Determining resistance to Fusarium verticillioides and fumonisin accumulation in African maize inbred lines resistant to Aspergillus flavus and aflatoxins
(University of Nairobi, 2017)
Fusarium verticillioides and Aspergillus flavus cause Fusarium ear rot (FER) and Aspergillus ear rot (AER) of maize, respectively. Both pathogens are of concern to producers as they reduce grain yield and affect quality. ...
Molecular profile of malaria drug resistance markers of Plasmodium falciparum in Suriname
(University of Nairobi, 2017)
In Suriname, an artesunate monotherapy therapeutic efficacy trial was recently conducted to evaluate partial artemisinin resistance emerging in Plasmodium falciparum We genotyped the PfK13 propeller domain of P. falciparum ...
Genetic characterisation of plasmodium falciparum isolates with deletion of the PFHRP2 and/or PFHRP3 genes in Colombia: The amazon region, a challenge for Malaria diagnosis and control
(University of Nairobi, 2017)
Most Plasmodium falciparum-detecting rapid diagnostic tests (RDTs) target histidine-rich
protein 2 (PfHRP2). However, P. falciparumisolates with deletion of the pfhrp2 gene and its
homolog gene, pfhrp3, have been detected. ...
Histidine-rich protein 2 (pfhrp2) and pfhrp3 gene deletions in Plasmodium falciparum isolates from select sites in Brazil and Bolivia
(University of Nairobi, 2017)
More than 80% of available malaria rapid diagnostic tests (RDTs) are based on the detection of histidine-rich protein-2 (PfHRP2) for diagnosis of Plasmodium falciparum malaria. Recent studies have shown the genes that code ...
Structural and optical properties of phosphorous and antimony doped ZnO thin films deposited by spray pyrolysis: a comparative study
(University of Nairobi, 2017)
A study of structural and properties of pure (undoped) Zinc oxide (ZnO) and phosphorous (P) and Antimony
(Sb) doped Zinc Oxide films has been carried out. The films were deposited by an automated spray pyrolysis
equipment ...

Phytoremediation using bamboo to reduce the risk of chromium exposure from a contaminated tannery site in Kenya
(University of Nairobi, 2017)
Background. This study examines an intervention strategy to reduce the risk of chromium (Cr) exposure. It follows a previous Cr exposure investigation, which revealed that large volumes of Cr-contaminated waste were burnt ...
Management of snap bean insect pests and diseases by use of antagonistic fungi and plant extracts.
(University of Nairobi, 2017)
Use of synthetic pesticides reduces the competitiveness of Kenyan snap bean pods due to stringent regulations
by importers as a result of presence of chemical residues. This study was conducted to determine the
effectiveness ...
Effects of Medicinal Plant Extracts and Photosensitization on Aflatoxin Producing Aspergillus flavus (Raper and Fennell)
(University of Nairobi, 2017)
This study was undertaken with an aim of exploring the effectiveness of medicinal plant extracts in the control of aflatoxin production. Antifungal properties, photosensitization, and phytochemical composition of aqueous ...
Perpendicular magnetic anisotropy in Mn2VIn (001) films: An ab initio study
(University of Nairobi, 2017)
First principles study of the magnetic anisotropy of Mn2VIn (001) films show perpendicular magnetic anisotropy (PMA), which increases as a function of the thickness of the film. Density functional theory (DFT) as implemented ...
