Research ArticleOpen accessIn the abstractInvolvement of Microsomal Na+/K+ ATPase Activity in the Mechanism of Action of Dopaminergic D2 ReceptorsAbdulrahim Abu-JayyabProblem statement: Our previous research has shown that mitochondrial ATPase may have a role in the action of dopaminergic D2 receptors. It is therefore, thought of interest to investigate the effect of bromocriptine, sulpiride or their combination on the mitochondrial and microsomal ouabain sensitive and ouabain insensitive Na+/K+-ATPase in the liver of rats. Approach: In vivo treatment was carried out … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 6,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotent Antielastase and Antityrosinase Activities of Astilbe chinensisSeung-Hun Lee, Sandesh Sancheti, Shruti Sancheti, Sung-Yum SeoProblem statement: In the current scenario, photo-aging is a major problem causing skin wrinkling and hyperpigmentation. Therefore, elastase and tyrosinase inhibitors play an important role in the treatment of skin aging and thus, gaining a special attention in cosmetic industries. Approach: In the screening of Korean medicinal plants to search the potent elastase and tyrosinase inhibitors, the extract of the … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractCamel's Milk Protects Against Aluminum Chloride-Induced Normocytic Normocromic Anemia, Lipid Peroxidation and Oxidative Stress in Erythrocytes of White Albino RatsFahaid Al-HashemProblem statement: Aluminum (Al) is an indifferent element from a toxicological point of view. In recent years, however, Al has been implicated in the pathogenesis of several clinical disorders. One of the most frequently described problem in aluminum toxicity is anemia. The present study was carried out to determine the effectiveness of Camel’s milk in alleviating the toxicity of aluminum … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 8,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistribution of β-Glucosidase Activity within Aggregates of a Soil Amended with Organic FertilizersSaeid Hojati, Farshid NourbakhshProblem statement: Distribution pattern of enzyme activities in soil aggregate size classes as affected by organic amendments is not well understood. Approach: A study was conducted to evaluate the effects of repeated annual application of Cow Manure (CM), Sewage Sludge (SS) and Municipal Solid Waste Compost (MSW) on the distribution of β-Glucosidase (βG) activity within aggregates of a soil. Soil … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradative Plasmid and Heavy Metal Resistance Plasmid Naturally Coexist in Phenol and Cyanide Assimilating BacteriaBahig El. Deeb, Abdullah D. AltalhiProblem statement: Heavy metals are known to be powerful inhibitors of xenobiotics biodegradation activities. Alleviation the inhibitory effect of these metals on the phenol biodegradation activities in presence of heavy metals resistant plasmid was investigated. Approach: Combination of genetic systems of degradation of xenobiotic compound and heavy metal resistance was one of the approaches to the creation of polyfunctional strains … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 11,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractChaenomeles Sinensis: A Potent α-and β-Glucosidase InhibitorShruti Sancheti, Sandesh Sancheti, Sung-Yum SeoProblem statement: Glycosidase inhibitors are vital sources for the treatment of diabetes type II with a special importance in pharmacology, food industry and biotechnology, since for diabetes control, different diets and drugs, especially herbal medicines are recommended in this era. Approach: While screening for the potent natural glycosidase inhibitors, we found the fruits of Chaenomeles sinensis (C. sinensis), as the … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 1 · 31 Mar 2009 · 12,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Hormetic Behaviour of Drugs Binding to Different Redox States of Amine Oxidase EnzymesDeepak Narang, G. Reid McDonald, David J. Smith et al.Classical monoamine oxidases and copper-containing semicarbazide-sensitive amine oxidases are drug targets for a variety of established and novel pharmaceuticals used to treat conditions such as depression, Parkinsonism and inflammatory disorders. Development of enzyme inhibitors, both historically and currently, assumes an underlying adherence of these enzymes to Michaelis-Menten kinetic principles. In this mini-review, we discuss historical data from several laboratories and … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariations in Four Genotypes of Lentil under NaCl-Salinity StressM. Sidari, C. Santonoceto, U. Anastasi et al.Four lentil cultivars, Eston (E), Rossa of Castelluccio (RC), Pantelleria (P) and Ustica (U) differing in salt sensitivity, were examined for osmolyte contents and activities of α-amylase, β-amylase and α-glucosidase enzymes involved in seed germination, in absence as well as in presence of 50, 100, 150 and 200 mM NaCl. The inhibitory effects of NaCl differed, depending on the genotypes … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDFCite
