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 · 8,550 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 · 8,685 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 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 · 8,093 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 · 6,771 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 · 8,230 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 · 6,953 accessesView PDFCite
Research ArticleOpen accessIn the abstractInoculation of a Poultry Isolate Salmonella enteritidis on Egg Vitelline Membrane: Survival and Growth in Egg Components after Different Refrigeration Storage TimesZ.R. Howard, R.W. Moore, I.B. Zabala Diaz et al.An in vitro study was designed to determine the extent of Salmonella enterica serovar enteritidis survival and growth permissiveness in egg components isolated from shell eggs held at refrigeration temperature over an 8 week time period. Eggs were collected from a commercial laying facility at one-week intervals for eight weeks and stored at refrigeration temperature. After storage, eggs were dipped … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneration of Five New Musa Hybrids With Resistance To Black Sigatoka and High YieldRicardo Hernández, Teresa Ramírez, Juan Carlos Noa-Carrazana et al.The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases. From the obtained … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Application of Carhart Atom Pairs to Predict Anticonvulsant ActivityAlan Talevi, Julian J. Prieto, Luis E. Bruno-Blanch, Eduardo CastroAbout 50 million people in the world suffer from epilepsy, especially in childhood, adolescence and old age. Available treatment fails to control epilepsy in up to 30% of affected people. In developing countries, however, the amount of patients that do not receive adequate treatment climbs up to 75%. Moreover, the new generation of antiepileptic drugs (AEDs) causes important central and … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,857 accessesView PDFCite
