Synergistic anti-inflammatory activities of a new flavone and other flavonoids from Tephrosia hildebrandtii vatke
(University of Nairobi, 2020)
A new flavone, named hildeflavone (1) along with 7 other known flavonoids were isolated from the aerial parts of Tephrosia hildebrandtii Vatke. Their characterisation was based on NMR and MS data analysis. The anti-inflammatory ...
Radiometric Survey of the Tyaa River Sand Mine in Kitui, Kenya
(University of Nairobi, 2020)
Gamma spectroscopic analyses of sand and rock samples from Tyaa River report an average activity concentration of 33 ± 1, 55 ± 2.8 and 812 ± 40.46 Bqkg-1 for 226Ra, 232Th and 40K, respectively in the sand. A similar analysis ...
Spatial and temporal trends of polychlorinated biphenyls in water and sediment from Nairobi River, Kenya
(University of Nairobi, 2020)
Polychlorinated biphenyls (PCBs) are chemicals that have become ubiquitous environmental pollutants due to their past use, persistence, and long-range transport thus requiring continuous monitoring. Therefore, this research ...
Hybridized Robust Chemometrics Approach for Direct Rapid Determination of Trace Biometals in Tissue Utilizing Energy Dispersive X-ray Fluorescence and Scattering (Edxrfs) Spectrometry
(University of Nairobi, 2018)
Direct rapid energy dispersive X-ray fluorescence and scattering (EDXRFS) analysis of trace biometals in soft body tissues is important because it has an immense potential for biomedical applications. Unfortunately this ...
Trace Metal Biomarker Based Cancer Diagnostics in Body Tissue by Energy Dispersive X-ray Fluorescence and Scattering (Edxrfs) Spectrometry
(University of Nairobi, 2019)
Direct diagnosis and characterization of cancer in tissue via trace biometals analyzed by energy dispersive X-ray fluorescence (EDXRF) spectrometry is challenging, as it requires sensitive detection and accurate quantitative ...
Varietal differences in physiological and biochemical responses to salinity stress in six finger millet plants
(University of Nairobi, 2020)
Finger millet is an important cereal that is grown in semi-arid and arid regions of East-Africa. Salinity stress is a major environmental impediment for the crop growth and production. This study aimed to understand the ...
Antiplasmodial and antileishmanial flavonoids from Mundulea sericea
(University of Nairobi, 2020)
Five known compounds (1-5) were isolated from the extract of Mundulea sericea leaves. Similar investigation of the roots of this plant afforded an additional three known compounds (6-8). The structures were elucidated using ...
Diversity of Taenia and Hydatigera (Cestoda: Taeniidae) in domestic dogs in Kenya
(University of Nairobi, 2020)
Taenia species of domestic dogs can cause cysticercosis and coenurosis in a wide range of intermediate hosts including humans. Most taeniids of dogs are globally distributed, but some wildlife-transmitted species can be ...
Aflatoxin Proficiency Testing and Control in Kenya
(University of Nairobi, 2020)
Texas A&M AgriLife Research (hereafter AgriLife) introduced a quality systems approach to accurately measure and manage aflatoxin that resulted in improved food safety for approximately 10 million Kenyans. A quality systems ...
