Research ArticleOpen accessIn the abstractMonstrous Hazards Produced by High Radioactivity Levels Around Assiut Thermal Power PlantHany El-Gamal, Mohamed El-Azab Farid, Abdulla Ibrahim Abdel Mageed et al.The natural radioactivity level of heavy oil, ash and soil samples around Assiut Thermal Power Plant (ATPP) in Egypt was determined using gamma ray spectrometry. The average concentrations of 226Ra, 232Th and 40K in fly ash were found to be 2307±143, 1281±80 and 1218±129 Bq kg-1, respectively, while the corresponding values in soil samples were 2670±107, 1401±78 and 1495±100 Bq … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 17 Sep 2013 · 6,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractAqueous Stem Bark Extract of Spathodea campanulata (P. Beauv) Modulates Carbon Tetrachloride Induced Hepatic Damage in RatsCharles Ansah, Phyllis Elsie Dadzeasah, Emmanuel AsiamahThe objective of the present study was to evaluate the hepatoprotective and curative potential of the aqueous extract of the stem bark of Spathodea Campanulata (SCE) in a carbon tetrachloride-induced model of hepatotoxicity in rats. Rats pre-treated with 625 mg kg-1, 1250, 2500 mg kg-1 or silymarin (50 mg kg-1) p.o for 3 days were intoxicated with CCl4 (1 mL … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 1 · 27 May 2013 · 9,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcute Phase Proteins, Lipid Profile and Proinflammatory Cytokines in Healthy and Bronchopneumonic Water Buffalo CalvesSabry M. El-Bahr, Wael M. EL-DeebThe aim of the present study was to evaluate the diagnostic value of Acute Phase Proteins (APP), lipid profiles and proinflammatory cytokines in healthy and bronchopneumonic water buffalo calves. Therefore, sixty water buffalo calves (9±1 month old, 175±15 kg) were divided into two equal groups, the first group represented healthy, control, calves whereas calves of the second group were affected … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural and Dielectrical Properties of Sterilized Human TeethMostafa Fawzy Eissa, Hassan Mohamed El-Shamy, Hassan Saad HanafyProblem statement: This study investigated the changes in crystallinity and dielectrical properties (conductivity) that could be demonstrated in extracted human teeth (enamel and dentin) subjected to γ-radiation at the sterilization dose (25 kGy). Approach: Twenty human third molar teeth were used in the study. Teeth were prepared so forty enamel and dentin samples were obtained. The samples were divided into … …Physics International, Vol. 3, Issue 1 · 20 Dec 2012 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrace Elements Distribution in the Brain of Stressed RatsZerrouk Kamal, Mohamed Najimi, Mohammed Chigr et al.Because of their ability to modulate the Gamma Aminobutyric Acid (GABA) a receptor complex, the principal aim of the current work is to assess two essential heavy metals: Iron (Fe) and zinc (Zn) by atomic absorption in different brain areas of stressed rats. To do so, we investigated the effect of acute immobilization stress (single 1-hour session) on the distribution … …Neuroscience International, Vol. 3, Issue 2 · 14 Sep 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractGastroprotective Effect and Safety Assessment of Zanthoxylum Zanthoxyloides (Lam) Waterm Root Bark ExtractAlex Boye, George Asumeng Koffuor, Johnson Nyarko Boampong et al.Problem statement: Gastrointestinal ulcers account significantly for morbidity and mortality in Ghana. The study therefore investigated the gastroprotective effect of an ethanolic root bark extract of Zanthoxylum zanthxyloides and its safety for us. Approach: Gastric ulceration was induced in Sprague-Dawley rats with Indomethacin (25 mg kg-1, p.o) and was treated with 150, 250, or 500 mg kg-1 of the extract, … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 2 · 7 Aug 2012 · 8,499 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffective Atomic Number of Lead Sodium Borate Glass Systems at 662 keVP. Limkitjaroenporn, W. Chewpraditkul, J. Kaewkhao, S. TuscharoenMass attenuation coefficients of glass systems xPbO: 20Na2O: (80-x)B2O3 (x = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and 55% mol) were determined at 662 keV photon energy using gamma rays transmission method. The theoretical values of mass attenuation coefficients were calculated by WinXCom program. These coefficients were then used to determine the effective atomic numbers of … …Energy Research Journal, Vol. 2, Issue 1 · 14 Feb 2012 · 8,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on the Effects of Non-Normality on the Performances of Max-DEWMA Versus SS-DEWMA ChartsTeh Sin Yin, Michael Khoo Boon ChongProblem statement: The called the Sum of Squares Double Exponentially Weighted Moving Average (SS-DEWMA) chart which is effective in detecting shifts in the mean and/or variance is compared with the Max-DEWMA (called the maximum double exponentially weighted moving average) chart. The comparison is based on the assumption that the distribution of the quality characteristic of the process is normal or … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 18 Jan 2012 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractCondoms-As Sources of Extracellular Enzyme Producing MicrobesMadhusmita Mishra, Poulomi Nandy, Sarvani Debsarma et al.Problem statement: Condoms are widely used birth control measures which are made of natural latex or synthetic materials like polyurethane or polyisoprene as matrix with lubricants added to make them ready to use commodities. Absence of sterilization method along with presence of lubricant like petroleum jelly (that are applied on the outer surface), prompted the investigators to look for microbes … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,987 accessesView PDFCite
