Preparation, characterization, and optimization of primaquine-loaded solid lipid nanoparticles
(International Journal of nanomedicine, 2014-08-11)Primaquine (PQ) is one of the most widely used antimalarial drugs and is the only available drug that combats the relapsing form of malaria. PQ use in higher doses is limited by severe tissue toxicity including hematological- ... -
Evaluation of Textile Substrates for Dispensing Synthetic Attractants for Malaria Mosquitoes
(BMC- Parasites & Vectors, 2014-08-16)The full-scale impact of odour-baited technology on the surveillance, sampling and control of vectors of infectious diseases is partly limited by the lack of methods for the efficient and sustainable dispensing of attractants. ... -
Spatial Heterogeneity of Malaria Vectors and Malaria Transmission Risk Estimated Using Odour-Baited Mosquito Traps
(BMC- Malaria Journal, 2014-09-22)Prior to the commencement of a large-scale malaria intervention study on Rusinga Island, western Kenya, intensive baseline surveillance of the mosquito population was performed using odour-baited traps. The survey aimed ... -
Crop Damage by Granivorous Birds Despite Protection Efforts by Human Bird Scarers in a Sorghum Field in Western Kenya
(Journal of African Ornithology, 2014-11-14)Cereal crop damage from granivorous birds poses a serious food security problem for subsistence farmers in sub-Saharan Africa. In this region, farmers may rely on human ‘bird scarers’ to limit crop damage. Here we report ... -
In vitro antimicrobial activity of methanolic extracts of different Senna didymobotrya (Fresen.) H. S. Irwin & Barneby plant parts
(Editorial Manager® and ProduXion Manager® from Aries Systems Corporation, 2015)Background: Herbal medicines are used widely for primary health care in Kenya among rural populations where modern medicines are not affordable. The flowers, roots, stems and leaves of Senna didymobotrya have both antifungal ... -
Carbon dioxide exchange and its regulation in the main agro-ecosystems of Haean catchment in South Korea
(Elsevier, 2015)The Asian agricultural landscape, which accounts for approximately 12.6% of the world’s agricultural land, is highly heterogeneous due to the multicultural cropping system. Information regarding CO2 exchange and carbon (C) ... -
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Science+Business Media Dordrecht, 2015)Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ... -
The Afro-alpine dwarf shrub Helichrysum citrispinum favours understorey plants through microclimate amelioration
(Taylor & Francis, 2015)Background: Positive plant–plant interactions similar to specialised plant growth forms are potential strategies to overcome the environmental harshness of Afro-alpine ecosystems. However, knowledge about plant–plant ... -
Soil properties along a gradient from hillslopes to the savanna plains in the Lambwe valley, Kenya
(Elsevier, 2015)Changes in land use and management strongly affect the physical and chemical properties of soils and their ecological functions. Especially, regions in East Africa have experienced dramatic land use changes in the past, ... -
A prospective observational description of frequency and timing of antenatal care attendance and coverage of selected interventions from sites in Argentina, Guatemala, India, Kenya, Pakistan and Zambia
(BMC, 2015)The Global Network for Women’s and Children’s Health Research is one of the largest international networks for testing and generating evidence-based recommendations for improvement of maternal-child health in resource-limited ... -
Larviciding potency of water and ethanol extracts of Phytolacca dodecandra (L’ Herit) on Anopheles gambiae (Diptera: Culicidae)
(BioPublishe, 2015)Introduction: Plant extracts are an attractive target for search of effective malaria vector control agents. The reason for this is that they present a cost effective, target specific and bio-degradable insecticides. The ... -
Morphological, genetic and symbiotic characterization of root nodule bacteria isolated from Bambara groundnuts (Vigna subterraneaL. Verdc) from soils of Lake Victoria basin, western Kenya.
(Journal of Applied Biology and Biotechnology, 2015)Low soil nitrogen (N) is a major constraint for sustainable crop production in smallholder farming systems in Africa. Grain legumes such as bambara groundnuts (Vigna subterraneaL. Verdc). can form N fixing symbiotic ... -
