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 abstractNitric Oxide Donors with Therapeutic Strategic in Experimental Schistossomiasis MansoniWander Rogério Pavanelli, Jean Jerley Nogueira da Silva, Carolina Panis et al.Schistosomiasis, an immune disease, remains a major public health problem in endemic area. To determine the influence of Nitric Oxide (NO) on this disease, we tested two compounds (Trans-[Ru(bpy)2(NO)SO3](PF6)-PF6 and Na2[Fe(CN)5(NO)]-SNP, which releases NO when activated by biological reducing agents, in BALB/c mice infected subcutaneously by Schistosoma BH strains. The parasitic activity of NO-donors was evaluated in this model by … …American Journal of Immunology, Vol. 10, Issue 4 · 24 Feb 2015 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractELECTROLYSIS OF SWINE MANURE EFFLUENTS USING THREE DIFFERENT ELECTRODES Fe-Fe, Al-Al AND Fe-AlS. Rahman, M. S. BorhanSwine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 9 Oct 2014 · 9,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractRADIOSENSITIZATION OF CANCER STEM CELLS: TARGETING TGFβ, NOTCH OR TELOMERASE TO IMPROVE TUMOR RESPONSE O RADIOTHERAPYIgnacio Fernandez-GarciaRadiation resistant cancer stem cells are the main reason for treatment failure and tumor recurrence after cancer radiotherapy. Increasing biological evidences demonstrate that these cells possess the capacity to repair radiation induced DNA damage, protect themselves from radiation derived reactive oxygen species, survive and proliferate after several fractions of radiotherapy and finally, repopulate the heterogeneity of the tumor. Thus, targeting … …Current Research in Medicine, Vol. 5, Issue 2 · 16 Jul 2014 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractOlive Wastewaters' Impact on Oued Boufekrane in Meknes-TafilaletMajdouline Larif, Abdelmajid Soulaymani, Mohammed Hnach, Azzedine ElmidaouiProblem statement: Water quality of river Boufekrane is subject to heavy pollution exerted by population growth and industrial activity, including the OMW from the olive industry in which the presence of polyphenols and toxic effect dominant character may generate a higher organic pollution. Approach: Our objective is to "study the impact of OMW by analyzing the physicochemical parameters on seven … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 20 Apr 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractZinc Deficiency and Associated T-Cell Dysfunctioning among Human Immunodeficiency Virus SeropositivesM. Andrew Pradeep, M. Thiruvalluvan, V. Nalini, J. Stella MaryProblem statement: All the nutrients in the diet play a crucial role in maintaining an optimal immune response. In both, deficient and excessive intake of nutrients can have negative consequence on the immune status and susceptibility to a variety of pathogens. Zinc is an essential micronutrient for human growth development and immune function. It plays a vital role in structure … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 8,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntiproliferative Effects of Alkaloids Isolated from the Tuber of Stephania venosa via the Induction of Cell Cycle Arrest in Mammalian Cancer Cell LinesSirinapa Nantapap, Chatchanok Loetchutinat, Puttinan Meepowpan et al.Problem statement: S. venosa (Menispermaceae) is used in traditional medicine. The constituents of S. venosa belonging to showed remarkable cytotoxic activity. According to previous research, S. venosa contains several alkaloids, such as protoberberine stephanine cyclanoline and N-methylstepholidine, kamaline, (+)-N-carboxamidostepharine, (-)-O-methylstepharinosine, (-)-stepharinosine, aporphine (-)-O-acethylsukhodiamine and oxostephanosine. The chemical and biological investigations of this plant are interesting to bioassay-guided fractionation, particularly Antiproliferative … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,789 accessesView PDFCite

Research ArticleOpen accessIn the abstractHeat Balance Analysis During the Production of Jadomycin CT. J. Burdock, A. H. Giffin, M.S. Brooks, A.E. GhalyJadomycins are novel antibiotics that exhibit biological activity against bacteria and yeast and also demonstrate cytotoxicity against cancer cells. Jadomycin C was successfully produced from 10 L of fermentation media in a 19 L bioreactor using Streptomyces venezuelae ISP5230 which was shocked with ethanol. The bioreactor temperature and pH were successfully maintained at 30°C and 7, respectively. The heat of … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue-Green alga Spirulina sp. Part I. A Comparison with BiosorptionKatarzyna ChojnackaThe paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,702 accessesView PDFCite
