Characterization of body louse midgut proteins recognized by resistant hosts.
(1996)
The human body louse, Pediculus humanus, showed eighteen midgut proteins ranging between 12 and 117 kDa, when analysed by SDS-PAGE electrophoresis. Seven of them (12 kDa, 17 kDa, 29 kDa, 35 kDa, 40 kDa, 55 kDa and 97 kDa) ...
Immunization of rabbits with faecal extract of Pediculus humanus, the human body louse: effects on louse development and reproduction
(1997)
Immunization of rabbits with a faecal extract of the human body louse (Pediculus humanus) induced a high titre of specific IgG. The mean weight of blood taken by females fed on the immunized rabbits was significantly lower ...
Brain aging in a sample of normal Egyptians cognition, education, addiction and smoking.
(1997-05)
The impact of duration of education, cannabis addiction and smoking on cognition and brain aging is studied in 211 normal Egyptian volunteers with mean age 46.4+/-3.6 years (range: 20-76 years). Subjects were classified ...
Adsorption/Desorption and Mobility of Carbofuran in Soil Samples from Kenya
(University of Nairobi, 1996-04)
Growth rates of ferromanganese encrustations on rocks from the Romanche Fracture Zone, Equatorial Atlantic
(1992)
Based on radiochemical techniques, ferromanganese oxide crusts from the Romanche
Fracture Zone (RFZ) have accretion rates ranging between 1.4 and 2.8 mm/10 years. In
comparison with other ferromanganese deposits, the ...
Time Lag between Deforestation and Bird Extinction in Tropical Forest Fragments
(University of Nairobi, 1999)
ropical forests are becoming increasingly fragmented, threatening the survival of the species that
depend on them. Small, isolated forest fragments will lose some of their original species. What is uncertain is
how long ...
Glucose and proline metabolism in the in vitro propagated procyclic trypanosoma congolense
(1992)
The main purpose of this study was to determine the pathways involved in the catabolism of glucose and proline by in
vitro propagated Trypanosoma congolense. The procyclic Trypanosoma. congolense were cultured in. vitro ...
Effect of interfering ions on hexamethyldisiloxane microdiffusion method
(University of Nairobi, 1997-10)
Acid diffusion in the presence of hexamethyldisiloxane (HMDS) enables complete recovery of ionic fluoride from standards containing varying concentrations of aluminium as one of the main interfering ions. Acid diffusion ...
Comparison of two microdiffusion methods used to measure ionizable fluoride in cows' milk.
(University of Nairobi, 1995-08)
Two microdiffusion methods for measuring ionizable fluoride in cows' milk have been compared. The comparison includes diffusion time, amount of fluoride in spiked and unspiked milk samples and the effect of aluminium as ...
