Research ArticleOpen accessIn the abstractHarmonics Phase Shifter for a Three-Phase System with Voltage Control by Integral-Cycle Triggering Mode of ThyristorsI. Badran, A.L. Mahmood, M.T. LazimIn integral-cycle triggering mode of voltage control, subharmonic as well as higher order harmonic components are generated in the load voltage waveforms of a three-phase system. These harmonic components are found to be unbalanced in phase displacement. The correction of the unbalanced phase displacement angles of a particular subharmonic or higher order harmonic for this type of triggering is investigated … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,110 accessesView PDFCite
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 abstractPatient and Mouse Antibodies against Dengue Virus Nonstructural Protein 1 Cross-React with Platelets and Cause Their Dysfunction or DepletionChiou-Feng Lin, Huan-Yao Lei, Ching-Chuan Liu et al.Thrombocytopenia is a clinical manifestation in dengue virus (DV) infection, yet its pathogenic mechanisms are unresolved. We previously showed that dengue patient sera contained antibodies cross-reactive with platelets. In this study, we demonstrated that the anti-platelet activity of dengue patient sera was due to the antibodies against DV nonstructural protein 1 (NS1). Studies using DV-infected or recombinant NS1-immunized mouse sera … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractCo-expression of Apoptosis-Related Molecules on Activated CD8+ CD38+ T-cells is Associated with HIV-1 Disease ProgressionJosé W. Rodríguez, Luis A. Rodríguez, Griselle Font et al.CD8+ T cells play a major role in controlling HIV-1 infection through the release of soluble lytic and non-lytic antiviral factors. Their decrease or defective function contributes to the HIV-1 disease progression. HIV-1 disease progression has been associated with a remarkable increase of CD38 expression on CD8+ T-cells. It has been also documented that a significant distribution of HIV-specific CD8+T-cells … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunodeficient Parameters in the HIV-1 Transgenic Rat ModelSulie L. Chang, Frank Ocasio, Jose A. BeltranRecently an HIV-1 transgenic (HIV-1Tg) rat model was created that carries a gag-pol-deleted HIV-1 genome under the control of the HIV-1 viral promoter. However, other viral proteins are expressed in most organs and tissues, and are found in the circulating blood. Since HIV-1 targets the immune system in humans, we examined two immunological parameters, leukocyte-endothelial adhesion (LEA) and inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,834 accessesView PDFCite
Research ArticleOpen accessIn the abstractOperational Semantics for Lazy EvaluationMahmoud A. Abou Ghaly, Sameh S. Daoud, Azza A. Taha, Salwa M. AlyAn operational semantics for lazy evaluation of a calculus without higher order functions was defined. Although it optimizes many aspects of implementation, e.g. there is a sharing in the recursive computation, there is no α conversion, the heap is automatically reclaimed, and an attempt to evaluate an argument is done at most once. It is still suitable for reasoning about … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,705 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmetine produce Entamoeba histolytica Death by Inducing a Programmed Cell DeathJ.D. Villalba-Magdaleno, R. Rojas, C. Gómez et al.Amoebiasis is a major public health problem in tropical and subtropical countries. Although a number of antiamoebic agents are used for its treatment and the molecular targets of these drugs have been identified, the biochemical and physiological mechanisms that produce trophozoite death are little known. The present study dates the in vitro induction of programmed cell death (PCD) in E. … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Vitamin C on the Metabolic Parameters of Experimental Diabetes MellitusMariam Al-Shamsi, Amr Amin, Ernest AdeghateThe role of vitamin C on diabetes mellitus is unknown. The purpose of this study was to examine the effect of oral administration of vitamin C on some of the metabolic parameters of diabetic rats. Diabetes was induced by intraperitoneal injection of STZ (60 mg kgˉ1 body weight at 12 weeks of age). Vitamin C (10, 50, 100 mg kgˉ1 … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 1 · 31 Mar 2007 · 8,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetinoids Chemosensitize Ovarian Cancer Cell Lines to Cisplatin Independent of Nuclear Receptors and p53Suresh Guruswamy, Doris M. BenbrookTreatment of ovarian cancer with cisplatin-based chemotherapy is highly toxic and is often followed by cancer recurrence. Repeated treatments with cisplatin frequently result in the development of resistance to this drug. Drugs with low toxicity that could enhance the tumor cell killing effects of cisplatin could potentially reduce the toxicity and enhance the efficacy of cisplatin. The mechanism of cell … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2006 · 6,958 accessesView PDFCite
