Fasciola gigantica: Comparison of the tegumental ultrastructure in newly excysted metacercariae and in vitro penetrated juvenile flukes indicates intracellular sources of molecules with vaccinal and immunomodulatory potential
(Elsevier, 2019)Using in vitro procedures to prepare newly excysted metacercariae and gut-penetrated juvenile Fasciola gigantica, the ultrastructural features of the tegumental syncytium and perikarya of these ephemeral stages in the ... -
Fasciola gigantica: ultrastructural cytochemistry of the tegumental surface in newly-excysted metacercariae and in vitro-penetrated juvenile flukes informs a concept of parasite defence at the interface with the host
(Elsevier, 2019)Cytochemical staining techniques were carried out en bloc with in vitro excysted and gut-penetrated Fasciola gigantica larvae in order to visualise the glycocalyx of the tegument, a structure which comprises the parasite ... -
Fundamental Investigation of Vesicle Bilayer Membrane Dynamics
(Western Michigan University, 2007)We studied the bilayer of vesicles from dimyristolyphosphatidylcholine (DMPC), using nitrobenzoxadiazole (NBD) probes, attached to the head (NBD-PE) and the tail (NBD-PC) of phospholipid derivatives. We characterized the ... -

A Geographic Information System Applied To A Malaria Field Study In Western Kenya
(Masaimara university, 1998)This paper describes use of the global positioning system (GPS) in differential mode (DGPS) to obtain highly accurate longitudes, latitudes, and altitudes of 1,169 houses, 15 schools, 40 churches, four health care centers, ... -
Grass-Like Plants Release General Volatile Cues Attractive for Gravid Anopheles Gambiae S.S. Malaria Vector Mosquitoes
(Research square, 2021)Understanding the ecology and behaviour of disease vectors, including the olfactory cues used to orient and select hosts and egg-laying sites, are essential for the development of novel, insecticide-free control tools. ... -
Growth and Gas Exchange Responses of Maize and Banana Plants in an Intercrop with Agroforestry Tree Species in Vihiga County, Kenya
(Asian Journal of Research in Crop Science, 2021)Agroforestry trees have been reported to improve soil fertility through nitrogen fixation, coupled with leaves and twig decomposition. High human population pressure in Vihiga County has led to reduced land area under ... -
