Vitamin B6 deficiency was induced in mice by maintenance for 4 weeks on a vitamin B6-free diet. Tryptophan metabolism was assessed by determining the urinary excretion of tryptophan metabolites, the metabolism of [14C]tryptophan ...

Electron microscope observations on enlarged hypertrophied salivary glands dissected from adult laboratory-reared male Glossina morsitans morsitans show a concurrent infection of the salivary gland tissue with rod-shaped ...

Monitor lizards were sampled along the shores of Lake Victoria to detect natural infections of potentially human-infective trypanosomes. In an area with endemic rhodesian sleeping sickness, one of 19 lizards was infected ...

The most critical periods of infection of French beans were planted at two sites--Kabete, where temperatures are cool and Naivasha, where it is warmer. They were inoculated with the rust pathogen at six different stages ...

Patients infected with Schistosoma mansoni showed an abnormal response to a test dose of tryptophan, with little increase in the urinary excretion of kynurenine, hydroxykynurenine, xanthurenic and kynurenic acids, N1-methyl ...

An explicit finite-difference method is used to simulate the thermal performance of short-term thermal storage for a focusing, indoor, institutional, solar cooker. The cooker storage unit consists of a cylindrical solid ...

Root dip in the extracts of Datura metel, Ricinus communis and Galium aparinoides significantly reduced infection by Meloidogyne incognita on okra. Soil amendment with these plants had a similar effect. Plant growth improved ...

Chorionic sculpturing on eggs of Phlebotomus pedifer Lewis, Mutinga, and Ashford; the closely related Phlebotomus aculeatus Lewis, Minter, and Ashford (= P. elegonensis Ngoka, Madel, and Mutinga); and Phlebotomus martini ...

In mice, infection with 20–30 cercariae of Schistosoma mansoni resulted in a considerable reduction in the formation of 14CO2 from [14C]tryptophan. Infected animals excreted significantly lower amounts of kynurenine, ...
