Antibody responses to plasmodium falciparum 3d7 rh5 and eba-175 antigens in an acute and convalescent cohort of children from Junju sub-location in Kilifi, Kenya.
(University of Nairobi, 2020)Repeated exposure to malaria parasites broadens the repertoire of antigens recognized by the host immune system leading to acquisition of immunity to the disease. This immunity is inefficient in the absence of exposure as ... -
Induction of secondary metabolites by endophytic fungi inphaseolus vulgaris for liriomyza leafminer and fall armyworm management.
(University of Nairobi, 2021)The Liriomyza leafminer flies (LMF) are invasive pests that attack several horticultural crops one of which is the common bean Phaseolus vulgaris. Endophytic fungi have been shown to deter performance, oviposition and ... -
Rapid assessment of calcium carbide ripened bananas using machine-learning assisted laser Raman spectroscopy.
(University of Nairobi, 2021)Fruit ripening is usually a natural process in which fruits undergo various chemical and physical changes before they become palatable. New artificial ways of fruit ripening have been developed as a result of recent ... -
