Biofuel Production versus Food Security in Kenya
(AJPS, 2023-08)
Biofuels are essential to fulfilling the United Nations Sustainable Development Goals, which place a strong emphasis on ensuring global food and energy security. Itis critical to comprehend how ...
Ultrasensitive immunosensor for multiplex detection of cancer biomarkers carcinoembryonic antigen (CEA) and yamaguchi sarcoma viral oncogene homolog 1 (YES1) based on eco-friendly synthesized gold nanoparticles
(University of Nairobi, 2023)
Cancer is one of the most extensive diseases with the highest mortality rate, accounting for almost 10 million deaths in 2020. The most common cancers are breast, lung, colon and rectum and prostate cancers. Of these, lung ...
Lead content in automotive paints purchased at formal and informal outlets in Kenya
(University of Nairobi, 2023)
Lead (Pb) is added to automotive paints to prevent corrosion on metallic surfaces, for decorative colours, and for reflective properties to heighten visibility, and enhanced drying time, and durability. However, there are ...
Fabrication of surface-enhanced Raman spectroscopy substrates using silver nanoparticles produced by laser ablation in liquids
(University of Nairobi, 2023)
This research describes the use of surface-enhanced Raman spectroscopy (SERS) substrates based on colloidal silver nanoparticles (AgNPs) produced by laser ablation of silver granules in pure water that are inexpensive, ...
Assessment of the effects of climate change on the occurrence of tomato invasive insect pests in Uganda
(University of Nairobi, 2023)
The shift in the geographical spread of invasive pests in Africa has rarely been linked directly to climate change. However, it is predicted that environmental changes play a significant role in spreading and expanding ...
Herminthology: promoting gender equity in science and parasitology
(University of Nairobi, 2023)
Gender inequity in Science, Technology, Engineering, and Medicine (STEM) fields, including parasitology, continues to limit the participation of women in scientific leadership and development. Here we highlight the aims ...
Recalibrating prognostic models to improve predictions of in-hospital child mortality in resource-limited settings
(University of Nairobi, 2023)
Background: In an external validation study, model recalibration is suggested once there is evidence of poor model calibration but with acceptable discriminatory abilities. We identified four models, namely RISC-Malawi ...
Methods of In Ovo and Ex Ovo Ostrich Embryo Culture with Observations on the Development and Maturation of the Chorioallantoic Membrane
(University of Nairobi, 2023)
Culture of shell-free and windowed eggs for drug testing and other experiments has been perfected for smaller eggs such as those of chickens, where the developing blood vessels of the chorioallantoic membrane (CAM) become ...
Rapid and non-destructive identification of Anopheles gambiae and Anopheles arabiensis mosquito species using Raman spectroscopy via machine learning classification models
(University of Nairobi, 2023)
Background: Identification of malaria vectors is an important exercise that can result in the deployment of targeted control measures and monitoring the susceptibility of the vectors to control strategies. Although known ...
A new C-C linked benzophenathridine-2-quinoline dimer, and the antiplasmodial activity of alkaloids from Zanthoxylum holstzianum
(University of Nairobi, 2023)
The CH2Cl2/MeOH (1:1) extract of Zanthoxylum holstzianum stem bark showed good antiplasmodial activity (IC50 2.5 ± 0.3 and 2.6 ± 0.3 µg/mL against the W2 and D6 strains of Plasmodium falciparum, respectively). From the ...
