Agro-Morphological Characterization of Kenyan Slender Leaf (Crotalaria brevidens and C. ochroleuca) Accessions
(Hindawi, 2020-04)Slender leaf (Crotalaria spp) is among the indigenous and underutilized vegetables in Kenya whose production is limited to the Western and Coastal regions of the country. For a long time, this crop has been neglected in ... -
STIP1/HOP Regulates the Actin Cytoskeleton through Interactions with Actin and Changes in Actin-Binding Proteins Cofilin and Profilin
(MDPI, 2020-04)Cell migration plays a vital role in both health and disease. It is driven by reorganization of the actin cytoskeleton, which is regulated by actin-binding proteins cofilin and profilin. Stress-inducible phosphoprotein ... -
Cervical Dysplasia, Infection, and Phylogeny of Human Papillomavirus in HIV-Infected and HIV-Uninfected Women at a Reproductive Health Clinic in Nairobi, Kenya
(Hindawi, 2020-06)High risk human Papillomavirus (HPV) infections ultimately cause cervical cancer. Human Immunodefi ciency Virus (HIV) infected women often present with multiple high-risk HPV infections and are thus at a higher risk of ... -

Variation in Seagrass Carbon Stocks Between Tropical Estuarine and Marine Mangrove-Fringed Creeks
(Frontiers in Marine Science, 2020-08)Seagrass and associated blue carbon ecosystems are important carbon sinks, and hence understanding their spatial and temporal variability is vital in appreciating their potential roles in climate change mitigation and ... -
Diversity and structure of prokaryotic communities within organic and conventional farming systems in central highlands of Kenya
(PLOS, 2020-08)Management practices such as tillage, crop rotation, irrigation, organic and inorganic inputs application are known to influence diversity and function of soil microbial populations. In this study, we investigated the ... -
A hybridization technique for orphan legumes: development of an artificial interspecific pollination protocol for Crotalaria spp.
