Resistance of falciparum malaria to chloroquine (CQ) has gradually emerged in the late 1970s, reaching unacceptably high proportions over the following three decades of use as frst line treatment in Sudan. By 2004-2006 CQ was replaced by artemisinin-based combination treatment (ACTs), with combination of sulfadoxine-pyrimethamine (SP) and artesunate (AS) deployed as frst-line drug against falci...

A rapid and sensitive method based on ultrafast liquid chromatography-tandem mass spectrometry was developed and validated for simultaneous determination of Sudan I, Sudan II, Sudan III, and Sudan IV levels in rat whole blood. Cleanert C18 mixed-mode polymeric sorbent was used for effective solid-phase extraction cleanup. Separation was carried out on a reversed-phase C18 column (100 mm×2.1 mm,...

Botek P., Poustka J., Hajšlová J. (2007): Determination of banned dyes in spices by liquid chromatography–mass spectrometry. Czech J. Food Sci., 25: 17–24. A simple and rapid multiresidue method for the determination of nine banned synthetic dyes in various spices has been developed. Reversed phase HPLC coupled with mass spectrometry (tandem in time – ion trap mass analyser) was employed for th...

A seroepidemiologic survey was conducted among 773 male soldiers living in five urban locations in Sudan to study the prevalence of and risk factors for HIV-1 and hepatitis B transmission. Twenty-eight per cent of the study population were born and raised in southern Sudan, an area bordering Kenya, Zaire and Uganda, whilst 72% of the study subjects were from northern Sudan. Seventy-eight per ce...

AIM To determine the population access to salt/iodized salt during and after the armed conflict in south Sudan and to illustrate geographical variations in population consumption of iodized salt in south Sudan after the armed conflict. METHODS The sources of data for the conflict period were the 2004 Toward a Baseline: Best Estimates of Social Indicators for Southern Sudan study report and th...

in an attempt to characterize theileria parva parasites circulating in south sudan cattle , polymerase chain reaction (pcr)-based assays were carried out using four single copy encoding antigen genes p104, pim, p150 and p67 in addition to one microsatellite ms321. a total of 20 bovine dna samples from two locations in south sudan were included in this study, in addition to two references strain...

A method to extract and analyze Sudan I present in Sunset Yellow FCF (SYF) products was developed and validated. The method included the simple extraction of Sudan I from the SYF product using water, acetonitrile, and ethyl acetate and high-performance liquid chromatography (HPLC) analysis with isocratic elution using acetonitrile:water (7:3) with a photodiode array detector at 485 nm. This met...

The major objective of this paper is to assess and to quantify the consequences of the Uruguay Round Agreement on Agriculture (URAA) on the agricultural trade of Sudan. Agriculture is the main sector of Sudan's economy. Sudan is characterized by its small open economy, and is classified as one of the least developed countries. Thus, Sudan becomes more vulnerable to any changes in international ...

Herein, a novel electrochemical method was developed for the determination of Sudan II based on the electrochemical catalytic activity of graphene modified glassy carbon electrode (GME) and the enhancement effect of sodium dodecyl sulfate (SDS). In a pH 6.0 phosphate buffer solution, Sudan II exhibited a pair of well-defined quasi-reversible redox peaks at the GME in the presence of 5.0×10 mol ...

Although the incidence of rheumatic fever (RF) and rheumatic heart disease (RHD) has declined in the developed world and many developing countries, yet it is still high in many countries including Sudan. The decline of frequency of RF in these countries is largely due to improved medical services leading to wide use of antibiotics to treat bacterial pharyngitis. In many developing countries, th...
