Research ArticleOpen accessIn the abstractMicrobial Response to the Application of Amendments in a Contaminated Soil with Trace ElementsA. Branzini, M. S. Zubillaga, M. M. ZubillagaProblem Statement: The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ-Glucans and ProbioticsMattia Pia Arena, Giuseppe Spano, Daniela FioccoIn the recent decades, several health-promoting features have been ascribed to β-glucans. Biological properties such as anti-cancer, anti-inflammatory and immune-modulating activity have been claimed for these polysaccharides. Moreover, when β-glucans were used in association with probiotic bacteria, prebiotic effects have been demonstrated, due to their ability to enhance growth, metabolism and/or beneficial activities of probiotics. This review shall present an … …American Journal of Immunology, Vol. 13, Issue 1 · 12 Apr 2017 · 9,145 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Synthesis of Endangered Frog Alkaloid ’Epibatidine’, A Potent Analgesic of the FutureN.R. Dhatrak, M.G. Kulkarni’Epibatidine’ is a nicotinic alkaloid’, was first discovered in the skin of neotropical poisonous frog, ’Epipedobates tricolor’ found in Ecuador. John Daly in 1974 first isolated a trace quantity of this alkaloid by scarifying several frogs. With the evolution of NMR techniques the structure of this alkaloid was reported in 1992. An year after, Nobel Laureate Prof. E.J. Corey, devised … …Current Research in Drug Discovery, Vol. 1, Issue 2 · 26 Jan 2015 · 17,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ1,3-GLUCAN ANTICANCER EFFICACIES AND SYNERGIES: A REVIEWStory Jenny, Vetvicka Vaclav, Angove Michaelβ1,3-glucans from fungi, cereals, seaweeds and bacteria have been shown to possess favourable biological and anti-carcinogenic activities including upregulation of phagocytosis, cytokine production enhancement, superoxide and nitrite production; antibody secretion and stimulation of signalling pathways associated with proto-oncogene expression. However, human dietary supplements containing β1,3-glucans vary in efficacy due to glucan source, the lifecycle stage of the source at extraction, … …American Journal of Immunology, Vol. 10, Issue 3 · 3 Sep 2014 · 8,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Characterization of Antibiotic-Producing Actinomycetes IsolatesMeera Kumari, Bat-Erdene Myagmarjav, Birendra Prasad, Madhusudan ChoudharyActinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred seventy five strains of … …Current Research in Microbiology, Vol. 4, Issue 1 · 25 Jun 2013 · 15,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison and Analysis of Vertical Coherence in the Shallow Water of Two ocean regionV. G. Sivakumar, V. Rajendran, R. SaranyaNoise characteristics at shallow water is highly variable due to wave guide nature of the shallow water environment, reflection of noise from the bottom surface; due to biological activities and also due the sound speed in shallow water vary substantially. Thus noise field characterization is complex in shallow water. The ambient noise data was collected in the shallow water of … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 5 Jun 2013 · 6,488 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Cancer Chemopreventive Activity of Styryllactones from Goniothalamus marcaniiChalong Mahiwan, Mongkol Buayairaksa, Narong Nuntasaen et al.Goniothalamus plants belonging to the family Annonaceae are found in Thailand and have been used as Thai traditional medicines. Members of this family are rich in a wide variety of biological active compounds including alkaloids, acetogenins and styryllactones. The present research described phytochemical study of the leaves and twigs of G. marcanii together with their cytotoxicity. The G. marcanii was … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 26 Jan 2013 · 7,679 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Handwriting Velocity to Identify Handwriting Process from Electromyographic SignalsMohamed Benrejeb, Afef Abdelkrim, Ines ChihiProblem statement: Handwriting movement is one of the most complex activities of human motions. It’s a blend of kinesthetic, cognitive, perceptual and motor components. The study of this biological process shows that a bell-shaped velocity profiles are generally observed in the handwriting motion. We, therefore, assume that the handwriting speed has an important role in control and generation of this … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 27 Aug 2012 · 7,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcological Monitoring of Danube water Quality in Budapest RegionHosam E.A.F. Bayoumi Hamuda, Istvan PatkoProblem statement: Serious health problems and other economic costs related to water treatment, remediation and locating a new water supply, become an evidence of water pollution caused by human activities. The main problems of the Danube River basin are associated with nutrients, organic pollution and hazardous pollutants. The aim of the study is to assess the surface water of the … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 5 Apr 2012 · 9,032 accessesView PDFCite
