Research ArticleOpen accessIn the abstractAnalgesic and Antioxidant Activity of the Hydromethanolic Extract of Mikania scandens (L.) Willd. LeavesS.M. Raquibul Hasan, Mariam Jamila, Muntasir Mamun Majumder et al.Problem statement: Mikania scandens (L.) Willd., a medicinal plant, is popularly used as herbal remedy for various ailments in Bangladesh. But the scientific basis for its medicinal use especially in pain and inflammation remains unknown. Therefore, the present study was designed to evaluate analgesic and antioxidant potential of the hydromethanol extract of the leaves of the plant. Approach: The analgesic … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 1 · 31 Mar 2009 · 12,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeating Effects on Structural and Electrical Properties of PolyetherimideNissaf Mzabi, Hichem Smaoui, Hajer Guermazi et al.Problem statement: Polyetherimide (PEI) has several uses such as electrical insulation. It can undergo different constraints like heat or high voltage which influence its performances as insulator. In this study, the effects of heating on structural and electrical properties of polyetherimide (Ultem 1000) are studied. Approach: PEI samples were heated at different temperatures below the glass transition temperature (175, 190 … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractLectin Histochemistry Assay in Colon Tissues for Inter-species CharacterizationFaezeh Yazdani Moghaddam, Jamshid Darvish, Nasser Mahdavi Shahri et al.Problem statement: The digestive tract of animals including rodents has taxonomic and ecologic importance due to its ability in adaptation for different environments. Whereas colon absorbs water and carbohydrates, it has a vital role ecologically and physiologically and enjoys different histological structures in different rodents with various diets. Approach: Different rodent specimens belong to the family Muridae, namely Gerbilinae subfamily … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,687 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 abstractProteins polymorphism of some populations of Lygeum spartum L. in AlgeriaAbderrezak Djabeur, Meriem Kaid-Harche, Douadi KhelifiLygeum spartum L. represent a natural barrier in the Algerian high plateaus against the advances of sand and turning into a desert. This species has two levels of ploïdy (diploïd cytotype 2n = 16 and polyploidy cytotype 2n = 40). Protein profile of several populations of this species have inter and intra specific variability. The polymorphic bands observed in the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractColourimetric Determination of Phospholipase Activities in Balamuthia mandrillarisSyed Razi HaiderBalamuthia mandrillaris is a recently identified protozoan pathogen that can cause fatal granulomatous encephalitis however the pathogenesis and pathophysiology associated with Balamuthia encephalitis remain unclear. We have recently isolated B. mandrillaris from a 33-years old male who died of encephalitis. Using this isolate, we demonstrated for the first time that B. mandrillaris exhibited phospholipase activities. More specifically, B. mandrillaris exhibited … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration. The calculated … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,234 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Proteolytic System of Candida dubliniensisLoaiza-Loeza Salomé, Parra-Ortega Berenice, Bautista-Muñoz Consuelo et al.Proteases of Candida dubliniensis have been scarcely studied, these enzymes may play an important role in nitrogen metabolism, post-translational processing, nutritional stress, dimorphism, virulence, etc. In this work, we report the presence of five different intracellular proteases and one extracellular proteolytic activity. The intracellular proteases are: aminopeptidase ycdAPE, carboxypeptidase ycdCP, dipeptidyl aminopeptidase ycdDAP, proteinases ycdPrA and ycdPrB, and extracellular protease … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 6,958 accessesView PDFCite
