Effect of four rounds of annual school-wide mass praziquantel treatment for schistosoma mansoni control on schistosome-specific immune responses.
(University of Nairobi, 2018)This study evaluated potential changes in antischistosome immune responses in chil-dren from schools that received 4 rounds of annual mass drug administration (MDA) of praziquantel (PZQ). In a repeated cross-sectional study ... -
Effect of Ga Incorporation and Film Thickness on the Optical Properties of as-Deposited Amorphous GaxSel-x Thin Films
(2014)Abstract: Flash evaporated amorphous Ga.Se i., (x = 0, I, 2, 3, and 4 atomic %) on glass substrates have bee. investigated within a 500nm-I500nm spectral range. Film thicknesses explored were; 200±IOnm, 265±IOnflJ. 330±IOnm, ... -
Effect of gibberellic acid (GA3) and temperature on seed germination of Rauvolfia serpentina
(College of Biological Sciences, University of Nairobi, 1970)GA was applied at 250, 500, 750 or 1000 mg/l. The 500-mg level in the laboratory increased germination from 5 (control) to 45.2%, and survival from 2 to 25.7%. Under field conditions the comparable figures for germination ... -
The Effect Of Immunizing Swiss White Mice With Snail Soluble Proteins And Challenging Them With Schistosoma Mansoni
(ISPUBSchool of Biological Sciences, University of Nairobi, 2012)Schistosomiasis infects approximately 700 million people in 74 endemic countries. It causes high morbidity. Although the drug of choice, Praziquantel is effective against Schistosoma mansoni, there is a problem of rapid ... -
