EditorialOpen accessIn the abstractCommentary-How do we Improve Training for Receptor Research?Marilee Ann BenoreThis issue of the American Journal of Biochemistry and Biotechnology features articles about receptor-ligand interactions that are critical to the wellbeing of all living organisms. The importance of the field of receptor research is supported by the large number of articles published in journals, the numerous specialty journals, the international conferences and the percentage of legal drugs on the market … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 8 Dec 2015 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstitutive Androstane Receptor Dependent and Independent Modulation of CYP3A2, CYP1A2 by Phenobarbital and Fibrate in Rats’ LiverMohamed Mohamed Ahmed, Mustafa Shukry, Zein Shaban Ibrahim et al.Cytochrome P450 enzymes, CYP3A and CYP1A are major drug metabolizing enzymes in the liver. CYP3A enzymes have a major role in the metabolism of 30-40% of all used drugs. CYP1A2 is a key enzyme having an important role in the metabolic clearance of 5% of currently marketed drugs. CYP1A2 participates in the metabolic activation of chemical mutagens in cooked food, … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,384 accessesView PDFCite
Research ArticleOpen accessIn the abstractFire Design: Direct Comparison Between Fire Curves. The Case Study of a NurseryMara Lombardi, Giuliano Rossi, Nicolò Sciarretta, Nino OrangesAccording to fire safety engineering, the present study analyzes fire design settings for simulation of fire in a nursery and proposes to compare simulations developed with a natural fire curve and nominal fire curve. Comparative analysis was developed according to thermo-fluid dynamic parameters that are relevant to the safety of the exposed and for the representative period of the danger … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 9 Sep 2013 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Stripping Frequency on Semen Quality of Endangered Caspian Brown Trout, Salmo trutta caspiusSaeed Hajirezaee, Bagher Mojazi Amiri, Ali Reza MirvaghefiProblem statement: Because of dramatic declines in stocks of endangered Caspian brown trout males, Salmo trutta caspius in Caspian Sea, each male brooder is stripped indispensably more than once during the spawning season in other to artificial insemination in hatchery. The aim of the present study was to assay the changes of indicators of semen quality (sperm motility, sperm production, … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 7,480 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 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Cellular Responses of Purine Nucleoside-mediated Protection of Hypoxia-induced Injuries of Neuronal PC12 CellsBettina Tomaselli, Valerie Podhraski, Günther Böck, Gabriele Baier-BitterlichHypoxia in brain may lead to cell death by apoptosis and necrosis. In parallel adenosine, a powerful endogenous neuroprotectant is formed. We wanted to investigate the effect of adenosine and its purine nucleoside relatives, inosine and guanosine on early cellular responses to hypoxia. O2-sensitive neuronal PC12-cells were subjected to chemical hypoxia induced with rotenone, an inhibitor of mitochondrial complex I. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,858 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLumbricus rubellus Protein Fraction DLBS1033N Increases Nerve Growth Factor Expression via Tyrosine Kinase ActivationAgung Heru Karsono, Raymond Rubianto Tjandrawinata, Maggy Thenawidjaja SuhartonoNerve injury occurred due to mechanical, thermal, chemical, or ischemic factors. Nerve regeneration is needed for recovery. Schwann cell proliferation and differentiation are important factors in the nerve regeneration process. Schwann cells release neurotrophins in the nerve regeneration process. In this study, Lumbricus rubellus protein fraction DLBS1033N was used as therapeutic protein candidate for nerve regeneration treatments. DLBS1033N treatments promoted … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 7 Feb 2018 · 9,410 accessesView PDFCite
