Review ArticleOpen accessIn the abstractEffects of Dietary Nucleotides on Immune Mechanisms and Physical State in Children with Chronic Respiratory ProblemsRichter Josef, Svozil Vladimir, Král Vlastimil et al.Heavy industrial pollution and/or passive smoking negatively affect the overall immune health of a population. We used a model of children with chronic respiratory problems and evaluated the effects of short term supplementation of their diet with nucleotides. We measured the level of sIgA, eNO levels and total physical activity. We found positive effects of oral supplementation with commercially available … …American Journal of Immunology, Vol. 11, Issue 2 · 12 Jun 2015 · 7,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Textile Dye Using Immobilized Bacterial (Pseudomonas aeruginosa) and Fungal (Phanerochate chrysosporium) CellsNatarajan Saravanan, Tiruvenkadam Kannadasan, Chiya Ahmed Basha, Veerasamy ManivasaganWastewater containing dyes presents a serious problem due to its high toxicity which leads to creating enormous environmental pollution and ecological hazards. Therefore the removal of the high stable dyes from the textile effluents is of major importance. The purpose of this study is to remove the reactive dye Procion Blue 2G from textile dye solution by biosorption process using … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 16 Sep 2013 · 7,358 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study on Natural Fibers for Green Acoustic Absorption MaterialsLamyaa Abd ALRahman, Raja Ishak Raja, Roslan Abdul RahmanNatural fibre materials are one of the major ways to improve environmental pollution and new materials need to be considered to find the best solutions. This study presents an experimental investigation on pure micro porous materials from two types of fibers: Date Palm Fibre (DPF) and Coconut Coir Fibre (CCF). This study was conducted to examine the potential for using … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 8,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicological Response of the Green Alga Chlorella vulgaris, to Some Heavy MetalsE. Afkar, H. Ababna, A. A. FathiProblems statement: The disturbance of aquatic ecosystems provoked by heavy metals pollution from industrial and domestic sources, has as consequence the loss of biological diversity, as well as increased bioaccumulation and magnification of toxicants in the food chain. The aim of this study was to evaluate the effect of some heavy metals on some physiological activities of Chlorella vulgaris beyerinck … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 10,787 accessesView PDFCite
