Research ArticleOpen accessIn the abstractInfluence of Ionizing Radiation on Antioxidant Enzymes in Three Species of TrigonellaMuna M. Al-Rumaih, May M. Al-RumaihThe response of three species of Trigonella, namely, Trigonella stellata, Trigonella hamosa and Trigonella anguina to gamma irradiation stress was investigated with respect to antioxidant enzyme induction. When dry seeds were subjected to gamma rays (0, 40, 60, 80, 100 Krad) from a cobalt source 60Co at a dose rate of 233.5 rad/ min, a dose dependent increase in the … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 8,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensitivities of Uterine Adenocarcinoma, Mixed Mullerian Tumor (MMT) and Sarcoma Cell Lines to Chemotherapeutic Agents and a Flex-Het DrugJohnny Hyde, Doris M. BenbrookThe administration and combination of a variety of chemotherapeutic agents for treatment of advanced or recurrent uterine cancer of different histologies is under current debate. Mixed Mullerian Tumors (MMTs), which contain both adenocarcinoma and sarcoma components, are the most rate histologic type and it is therefore difficult to conduct clinical trials to determine if they should be treated like endometrial … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2006 · 7,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimum Conditions for Measuring Dehydrogenase Activity of Aspergillus niger using TTCA. E. Ghaly, N. S. MahmoudThe suitability of the triphenyl tetrazolium chloride (TTC) for dehydrogenase activity measurement of the vegetative cells of the fungal species Aspergillus niger was investigated. The triphenyl formazan (TF) yield increased with the increases in TTC concentration, pH, temperature and incubation time within the studied ranges. The effects of individual parameters, as well as the combined effects, on the TF yield … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 9,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Pasteurella Multocida Infections over a Twelve-Year Period in a Tertiary Care HospitalAthanasia Christidou, Sofia Maraki, Zoe Gitti, Yiannis TselentisThe aim of this study was to present the epidemiological, clinical and microbiological data, as well as the management and the outcome of 13 patients with documented Pasteurella multocida infections, diagnosed in the University hospital of Crete, Greece, between 1993 and 2004. Most patients (62%) were >70 years of age. Respiratory tract infections were most commonly encountered (61.5%), followed by … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,996 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBacteria Contaminants and their Antibiotic Sensitivity from Selected Herbal Medicinal Products from Eldoret and Mombasa, KenyaLucia Keter, Richard Too, Nicholas Mwikwabe et al.Herbal products are used worldwide for the treatment and prevention of various diseases and currently represent a substantial proportion of the global drug market. However, these products have the potential of being contaminated by different microorganisms due to poor hygienic practices during handling, processing and packaging. The main aim of this study was to evaluate microbial quality of herbal products … …Current Research in Microbiology, Vol. 7, Issue 1 · 28 Jan 2016 · 17,160 accessesView PDFCite
