Sera collected in May 1984 from 132 adult residents of Karamoja district, Uganda, were examined by haemagglutination inhibition tests for antibodies against selected arboviruses, namely Chikungunya and Semliki Forest alphaviruses (Togaviridae); dengue type 2, Wesselsbron, West Nile, yellow fever and Zika flaviviruses (Flaviviridae); Bunyamwera, Ilesha and Tahyna bunyaviruses (Bunyaviridae); and...

South Sudan faces a myriad of challenges ranging from a struggling economy, low levels of technology to weak health care systems. It is a new country born out of a Comprehensive Peace Agreement between Sudan and the Sudan People’s Liberation Movement (SPLM). Its independence on July 9th, 2011, ended one of the longest protracted civil wars in Africa. The country has a population of about 12 mil...

Although various biological aspects of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) have been examined, adult movement and dispersal of this insect pest is not well understood. Release-recapture techniques by using marked insects is a useful approach for dispersal studies; however, the marking technique should not significantly affect insect biology or behavior. Therefore, the ef...

Climate change represents the major challenge to Sudan agricultural production, economics and food security. Changes in temperature, rainfalls, water availability, increased outbreak of pest and diseases, land degradation, soil erosion, shrinking of grazing and cultivate areas, ongoing desertification and the other aspects of climate change have direct significant impact on agricultural product...

1-Phenylazo-2-hydroxynaphthol (Sudan I, C.I. Solvent Yellow 14) is a liver and urinary bladder carcinogen in mammals. We compared the ability of hepatic microsomal samples from different species including human to metabolize Sudan I. Comparison between experimental animals and human cytochromes P450 (CYP) is essential for the extrapolation of animal carcinogenicity data to assess human health r...

Sudan I [1-(phenylazo)-2-hydroxynaphthalene, C.I. Solvent Yellow 14, CAS No: 842-07-9] is used as the compound employed in chemical industry and to color materials such as hydrocarbon solvents, oils, fats, waxes, plastics, printing inks, shoe and floor polishes and gasoline. Such a wide used could result in a considerable human exposure. Sudan I is known to cause developments of tumors in the l...

A set of intraveous injections of 7,8,12-trimethylbenz[a]anthracene consistently elicited leukemia in more than 75% of young adult Long-Evans female rats. There was a profound reduction in the incidence of leukemia in companion groups of rats fed small amounts (1--10 mg) of Sudan III or Sudan IV prior to each injection of the carcinogenic hydrocarbon. Repeated feedings of 1 mg of Sudan III indu...
