Research ArticleOpen accessIn the abstractContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 accessesView PDFCite
Research ArticleOpen accessIn the abstractProteomics Approach for Investigating the Disease Resistance Using Cucumber as Model PlantSaligrama A. Deepak, Junko Shibato, Hideo Ishii et al.The profile of proteins induced in cucumber leaves pretreated with Acibenzolar-S-Methyl (ASM) and challenge inoculated with Colletotrichum orbiculare are presented. ASM was applied to the first leaf and the third leaf collected at different time intervals of 0-48 h and the total protein extracted using trichloroacetic acid acetone was analyzed by two-dimensional gel electrophoresis. Increased expressions of pyridoxine biosynthesis protein, … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractSesame Oil As A Protective Agent Against Doxorubicin Induced Cardio Toxicity In RatKaneez F. Shad, Suhail Al-Salam, Alaaeldin A. HamzaThe therapeutic value of doxorubicin (DXO) as anticancer antibiotic is limited by its cardiotoxicity. This study aimed to investigate the protective effect of sesame oil against DXO-induced cardiotoxicity and oxidative stress. The administration of DXO (20 mg/kg) to Wister male rats, increased serum aspartate aminotransferase and creatine kinase activities (as cardiotoxicity indices) as well as cardiac malondialdehyde and protein carbonyl … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of D- and L-Glucose and Mannitol on Retinal Capillary Cells: Inhibition by Nanomolar AminoguanidineYongxin Yu, Wei Li, Barbara Wojciechowski et al.Hyperglycemia may contribute directly to pericyte loss and capillary leakage in early diabetic retinopathy. To elucidate relative contributions of glycation, glycoxidation, sugar autoxidation, osmotic stress and metabolic effects in glucose-mediated capillary damage, we tested the effects of D-glucose, L-glucose, mannitol and the potentially protective effects of aminoguanidine on cultured bovine retinal capillary pericytes and endothelial cells. Media (containing 5 mM … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Provenance of the Varzaneh Aeolian Sand Field Regarding to Lithology and Texture, SW Esfahan, IranH. Pakzad, R. AjalloeianThe main mineralogical/lithological composition of the Varzaneh aeolian sands is sedimentary and igneous lithics. The minor one is metamorphic lithics and mineral grains (such as quartz, feldspar and heavy mineral grains) respectively. The origin of the sedimentary lithics (mainly carbonates) mostly is from sedimentary rocks exposed in the west and the southwest of the study area. These rocks belong to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,199 accessesView PDFCite
