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...

Peroxidase in the presence of hydrogen peroxide catalyzes in vitro the activation of the carcinogenic azo dye Sudan I (1-phenylazo-2-hydroxynaphthalen) to tRNA-, homopolyribonucleotide- and 5'-monophosphate nucleoside-bound products. tRNA, poly G and guanosine 5'-monophosphate modified by activated Sudan I become colored and have an absorption maximum of approx. 480 nm. Cochromatographic analys...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...
