Research ArticleOpen accessIn the abstractConcentration and Physicochemical Properties of Chitosan Derivatives Determine the Induction of Defense Responses in Roots and Leaves of Tobacco (Nicotiana tabacum) PlantsAlejandro B. Falcón-Rodríguez, Juan C. Cabrera, Eduardo Ortega, Miguel Ángel Martínez-TéllezProblem statement: The chitosan derivatives promote diverse defensive responses in plants, which are affected by chitosan chemical features and concentration. Glucanase (EC 3.2.1.6), Phenylalanine Ammonia-Lyase (PAL, EC 4.3.1.5) and peroxidase (POD, EC 1.11.1.6) are key enzymes in tobacco defense responses. Thus, the aim of this study was to know the behavior of their enzymatic activity in leaves and roots of … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,263 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDrug Interaction between Salinomycin and Exogenous Adrenaline in DogsHamid Rajaian, Javad Sajedianfard, Saeed Nazifi, Ali Moosavi KianProblem statement: Salinomycin is a member of ionophore compounds that may be used in ruminants and pigs as growth promoter or to prevent coccidiosis. There are some reports with respect to the in vitro and in vivo sympathomimetic cardiovascular effects of salinomycin. Available reports indicate that adrenergic impact of the ionophore is brought about by an increase in the secretion … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 2 · 30 Jun 2009 · 7,541 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnti-Phytopthora capsici Activities and Potential Use as Antifungal in Agriculture of Alpinia galanga Swartz, Curcuma longa Linn, Boesenbergia pandurata Schut and Chromolaena odorata: Bioactivities Guided Isolation of Active IngredientsWilart Pompimon, Jinnantina Jomduang, Uma Prawat, Samlee MankhetkornProblem statement: Plant derived fungicides are now being subjects of many research groups. These secondary metabolites have enormous potential to inspire and influence modern agrochemical research. The study aimed to investigate the antifungal activity and their potential use as fungicides in the agriculture of crude extracts and purified compounds derived from plants used in traditional medicines. Approach: Four medicinal plants … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,704 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerspectives of Solid State Fermentation for Production of Food EnzymesCristobal Noe Aguilar, Gerardo Gutiérrez-Sánchez, PLilia A. rado-Barragán et al.Food industry represents one of the economic sectors where microbial metabolites have found a wide variety of applications. This is the case of some enzymes, such as amylases, cellulases, pectinases and proteases which have played a very important role as food additives. Most of these enzymes have been produced by submerged cultures at industrial level. Many works in the literature … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 10,654 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPlasmid-mediated Detoxification of Mycotoxin Zearalenone in Pseudomonas Sp. ZEA-1Abdullah D. AltalhiThe Pseudomonas sp. Strain ZEA-1 was isolated from rhizosphere of corn plant by an enrichment technique showed capability of utilizing zearalenone as the sole source of carbon. The bacterium rapidly utilized zearalenone beyond 200 µg/ml and showed prolific growth in a minimal medium containing 100 µg/ml zearalenone source. The course of ZEA degradation as well as the formation of its … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Postgenomic Era: Transcriptomic as the New Paradigm of LifeBruno Giardina, Marcella Renis, Vito Latora, Salvatore MusumeciNow that complete genome sequences are available for a variety of organism, the elucidation of single gene function involved in the metabolism, includes necessarily a better understanding of the cellular responses on all levels of gene products, mRNA, proteins and metabolites. Such knowledge’s growth is essential since the observable properties of living organisms, so called phenotypes, are the results of … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,822 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysical Basis of Magnetic Resonance Spectroscopy and its Application to Central Nervous System DiseasesNicolás Fayed, Salvador Olmos, Humberto Morales, Pedro J. ModregoMagnetic Resonance Spectroscopy is based on the chemical shift property of the atom nuclei when a magnetic field is applied. This technique offers invaluable information about living tissues with special contribution to the diagnosis and prognosis of the central nervous system diseases. Concentration of several metabolites can be assessed in a reproducible manner by means of modern clinical scanners. N-acetyl-aspartate … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,851 accessesView PDF Cite
