Research ArticleOpen accessIn the author namesGlutathione S-transferase (T1 & M1) Null Genotypes as Risk Determinants in Sudanese for Developing Type Two Diabetes MellitusGaafar Mahmoud, Hisham Mohamed Abdelrahim, Abed Al Salam Aljahmany, Eltayeb Mohamed Ahmed TayrabGlutathione S-transferases (GSTT1 and GSTM1) are globular proteins responsible for the detoxification of xenobiotics and the prevention of oxidative damage. Functional polymorphisms of the antioxidant glutathione and enzymes have a role in the pathogenicity of T2DM and its complications. The present study is aimed to assess association between GSTM1 and GSTT1 genetic polymorphisms with T2DM in Sudanese people. This case-control … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 16 Oct 2020 · 6,423 accessesView PDFCite
InvestigationOpen accessIn the author namesThe Technology of Cultivating Lump Crops with Mist Sprinkling in the Conditions of the Zhambyl RegionNurlan Nurmahanovich Balgabaev, Pavel Alexanderovich Kalashnikov, Aigul Eltaevna Baizakova, Alexander Afanasyevich KalashnikovIncreasing water scarcity and increasing rate of livestock development in the Republic of Kazakhstan require using new water-saving irrigation methods. Using new forage crops will make it possible to use irrigation water most productively and to achieve the maximum yield with high soil-feeding capacity, while using the minimum amount of irrigation water. Therefore, the main goal of the research was … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 14 Jun 2017 · 7,279 accessesView PDFCite
Research ArticleOpen accessIn the author namesTHE ELECTRICAL PROPERTIES OF Mg-Cu-Zn FERRITES IRRADIATED BY γ-RAYS OF 60Co SOURCEMohamed Eltabey, H. Ebrahim Hassan, Ismail Abd Elrahim AliFerrite samples with chemical formula MgxCu0.5-xZn0.5Fe2O4 (x = 0.0, 0.2 and 0.4) was prepared by the conventional ceramic method. The enhanced changes in the dc/ac resistivity and the dielectric constant due to γ-rays irradiation by 60Co source were measured using the two probes technique. The samples showed decreasing of their resistivity at room temperature after irradiation for both dc and … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntegrated Supercritical Fluid Extraction and BioprocessingOwen Catchpole, Stephen Tallon, Peter Dyer et al.Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO2 is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,488 accessesView PDFCite
