Research ArticleOpen accessIn the abstractProduction and Roles of Glial Tissue Inhibitor of Metalloproteinases-1 in Human Immunodeficiency Virus-1-Associated Dementia Neuroinflammation: A ReviewC. Chao, A. GhorpadeProblem statement: Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and its cognate targets, the Matrix Metalloproteinases (MMPs), were differentially expressed in human brain samples with or without HIV-1 infection or HIV-1 Encephalitis (HIVE). Approach: A through literature review demonstrated that cell culture models of Central Nervous System (CNS) cell types had been used to illustrate the intricate temporal patterns of TIMP-1/MMP expression, … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,953 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStressors Influence on Salmonella enterica Serovar Enteritidis Colonization in BroilersE. S. Soliman, E. Taha, K. D. Infante et al.Problem statement: Poultry industry usually exposing birds to a variety of actions and stressors includs fasting for gastrointestinal emptying before transportation and where birds are often exposed to high environmental temperature during the summer months. These environmental stressors may have influences on bird performance and susceptibility to pathogens such as Salmonella enteritidis by altering the intestinal micrbiota and changes in … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 12 Sep 2009 · 7,187 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHormetic and Non-Hormetic Dose-Response Functions in Stress Effects on Memory and Synaptic Plasticity: Issues and MechanismsPhillip R. Zoladz, David M. DiamondOver a century of behavioral research has shown that stress can exert both positive and negative effects on memory. We have explored the idea that the complex effects of stress on learning and memory can be characterized by hormetic- and non-hormetic dose-response functions, in which stress may either stimulate or impair brain memory mechanisms, depending, in part, on the timing … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,184 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHormesis and Exercise: How the Cell Copes with Oxidative StressLi Li Ji, Zsolt Radak, Sataro GotoContraction-induced production of reactive oxygen and nitrogen species has been shown to cause oxidative stress to skeletal muscle, heart and other organs. As an adaptive response, muscle antioxidant defense systems are upregulated in response to exercise to restore intracellular prooxidantantioxidant homeostasis. Thus, both young and old animals and humans involved in regular exercise have shown reduced oxidative damage during acute … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,817 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpirulina protects against cadmium-induced hepatotoxicity in ratsAmr Amin, Alaaeldin A. Hamza, Sayel Daoud, Waleed HamzaCadmium (Cd) is an environmental and industrial cumulative pollutant that most affects many organs specially the liver. The protective effect of Spirulina, filamentous blue green algae, on Cd – induced oxidative stress and hepatotoxicity was evaluated in male rats. Oral administration of water extract of Spirulina for seven days followed by an acute toxic dose of Cd (3.5 mg kg … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 2 · 30 Jun 2006 · 11,533 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIn-Vivo Evaluation of Hexavalent Chromium Induced DNA Damage by Alkaline Comet Assay and Oxidative Stress in Catla catlaKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Jaya Krishna KuruvaIn the present study, the acute toxicity of Chromium in fingerlings of Catla catla, an Indian major carp, was evaluated with renewal bioassay method. In vivo studies were designed to assess the extent of Micronucleus Assay, Comet Assay under the exposure of common heavy-metal compounds, namely, Chromium Nitrate, using Catla catla (2n = 20), as a test model. The laboratory … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 7,196 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe "Forgotten Side Effect" of ThiazidesArnon BlumProblem statement: Thiazide diuretics are derived from benzodiazines. They inhibit Na+/Cl- re-absorption from the distal convoluted tubules in the kidneys by blocking the thiazide-sensitive Na+/Cl- symporter. They are recommended as first line treatment for hypertension in the US (JNC VII)[1] guidelines and in the National Institute of Health and Clinical Excellence/British Hypertension Society guidelines[2] and in the European (ESC/ESH)[3] guidelines. … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 8,337 accessesView PDF Cite
