Research ArticleOpen accessIn the keywordsPrimary Pollutants Monitoring and Modeling Using Chemical Mass Balance (CMB) Around Fahaheel Residential AreaS. M. Al-Salem, A. A. Al-Haddad, A. R. KhanFour major sources of air pollution were identified and modeled using Chemical Mass Balance (CMB) around a residential area. The sources were identified as MAA refinery, downtown area, upstream facilities and main highway road. The sources were analyzed using a series of concentration roses (unfiltered and filtered) executed from the data collected. Data collected included primary and secondary pollutants levels … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,742 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAmbient Levels of Primary and Secondary Pollutants in a Residential Area: Population Risk and Hazard Index Calculation over a Three Years Study PeriodS. Al-Salem, A. Al-FadhleeThis paper aims at presenting data collected over the period of three years (2004-2006) in a residential area in the state of Kuwait. The data collected include ambient levels of primary and secondary pollutants with a number of metrological parameters. A series of unfiltered and filtered concentration roses were plotted to determine the predominant sources as well as the prevailing … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,457 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Vision-Based Approach to Real-Time Trust Evaluation within Multiagent SystemsAlan Kruger, Sun YiAs robotic autonomy increases, single-agent systems are evolving into more complex multiagent systems that require more factors for successful implementation. In exchange for this complexity, applications such as autonomous delivery services and reconnaissance swarms become possible when they are infeasible with only one agent. By incorporating Trust into the multiagent system, the complexity of the agent-to-agent relationships can be managed … …Journal of Mechatronics and Robotics, Vol. 9, Issue 1 · 21 Mar 2025 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Comparative Analysis on the Physiological Effects of the Physical and Chemical Properties of the Trihalomethanes on Nutrient Levels, Oxidative Stress and Sterol Compositions of Leaf Oils in Solanum Lycopersicum CultivarsBabatunde C. Akande, Olalekan S. Fatoki, James P. Odendaal et al.Trihalomethane group of disinfection by-products was used to evaluate the magnitude of physiological changes induced on nutrient levels, oxidative stress and phytosterol content in two tomato cultivars. The tomato cultivars were grown as potted plants in a greenhouse and exposed to the varying concentrations of trihalomethanes and organochlorines via irrigation water for a period of 30 days. The concentration levels … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 11 May 2018 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRADIOSENSITIZATION OF CANCER STEM CELLS: TARGETING TGFβ, NOTCH OR TELOMERASE TO IMPROVE TUMOR RESPONSE O RADIOTHERAPYIgnacio Fernandez-GarciaRadiation resistant cancer stem cells are the main reason for treatment failure and tumor recurrence after cancer radiotherapy. Increasing biological evidences demonstrate that these cells possess the capacity to repair radiation induced DNA damage, protect themselves from radiation derived reactive oxygen species, survive and proliferate after several fractions of radiotherapy and finally, repopulate the heterogeneity of the tumor. Thus, targeting … …Current Research in Medicine, Vol. 5, Issue 2 · 16 Jul 2014 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiomarkers of Oxidative DNA Damage and Soluble Fas/Fas Ligand in Type 2 Diabetic PatientsMohamed H. Mahfouz, Ibrahim A. Emara, Ghada A. OmarProblem statement: Involvement of oxidative stress in the pathogenesis of diabetic complications has been proposed. 8-hydroxy-2'-deoxyguanosine (8-OHdG) has been reported to serve as a new sensitive biomarker of the oxidative DNA damage in vivo. Apoptosis via Fas/Fas Ligand (FasL) interactions has been proposed to be a major T-cell-mediated effector mechanism in autoimmune diabetes. This study was undertaken to investigate whether … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 3 Feb 2012 · 7,106 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Melatonin in Prevention of Neuropathy in STZ-Induced Diabetic RatsNasser Zangiabadi, Vahid Sheibani, Majid Asadi-Shekaari et al.Problem statement: Diabetes mellitus occurs mainly with chronic polyneuropathy, and oxidative stress plays an important role in emergence of most neurologic and behavioral changes in diabetic patients. Many studies have focused on the beneficial effects of various antioxidants such as melatonin on diabetic neuropathy. The aim of this study is to evaluate the effect of melatonin in prevention of neuropathy … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Sep 2011 · 9,358 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of in vivo Antioxidant and Hepatoprotective Activity of Portulaca oleracea L. against Paracetamol-Induced Liver Toxicity in Male RatsMohamed H. AhmidaProblem statement: Oxidative stress plays a major role in paracetamol induced hepatotoxicity. Portulaca oleracea (P.O.) has been shown to exhibit antioxidant properties. The present study aimed to investigate the effect of P.O. on the oxidative stress in Paracetamol-induced hepatic toxicity in male rats. Approach: Forty male rats were divided into four groups. Group I served as control; Group II Received … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 4 · 13 Jun 2011 · 7,327 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProphylactic Effects of Melatonin on Sodium Valproate-Induced Neural Tube Defects and Skeletal Malformations in Rat EmbryosOmolbanin Rahgazar, Reza Ranjbar, Hossien Najafzadeh Varzi, Mahmood Khaksary MahabadyProblem statement: Some reports showed the teratogenic effects of sodium valproate can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. Therefore, in this study, the prophylactic effect of melatonin on teratogenic effects of sodium valproate was compared. Approach: This study was performed on 31 pregnant rats that were divided into five groups. Control group … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,281 accessesView PDFCite
