Research ArticleOpen accessIn the abstractHemodynamic Catheters: The Reprocessing, Cleanliness and in vitro Biofilm Formation by Enterococcus faecium in a Continuous Flow ModelCleber Galdino da Silva, Edson Pires de Oliveira, Ednalva Miranda Guizi et al.Reprocessing single-use devices to cut costs is a common practice in hospitals around the world. In Brazil, there are few studies of reprocessing hemodynamic catheters and thus, this study aimed to evaluate the effectiveness of reprocessing hemodynamic catheters before and after biofilm formation in vitro using a continuous flow model. We used a sterility test and Scanning Electron Microscopy (SEM) … …American Journal of Infectious Diseases, Vol. 11, Issue 2 · 24 Jul 2015 · 7,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractGRAPHENE OXIDE AS ANTIMICROBIAL AGAINST TWO GRAM-POSITIVE AND TWO GRAM-NEGATIVE BACTERIA IN ADDITION TO ONE FUNGUSRoda F. Al-Thani, Noorunnisa Khanam Patan, Mariam A. Al-MaadeedGraphene based materials have wide potential applications in biology, biomedical, agriculture environmental and biotechnology. Graphene Oxide (GO) is one of those materials and has a promising substance as antimicrobial agents. GO in this study was prepared by a modified Hummers method and was characterized by different techniques for confirmation of formation of GO. To study the antimicrobial activities of GO, … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 14 Oct 2014 · 9,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTUDY OF PHYSICO-CHEMICAL PROPERTIES OF THE SURFACE AND GROUND WATERA.Y. Al-Ghamdi, Mohamed El-Shahate Ismaiel Saraya, A.O. Al-Ghamdi, S.A. ZabinOf all the natural resources, water is unarguably the most essential and precious. Life began in water and life is nurtured by water. Ninety seven percent of the world’s water is found in oceans. Only 2.5% of the world’s water are non-saline fresh water. Saudi Arabia is a desert country with no permanent rivers or lakes and very little rainfall. … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 18 Apr 2014 · 7,794 accessesView PDFCite

Research ArticleOpen accessIn the abstractMeat Spoilage Mechanisms and Preservation Techniques: A Critical ReviewD. Dave, Abdel E. GhalyProblem statement: Extremely perishable meat provides favorable growth condition for various microorganisms. Meat is also very much susceptible to spoilage due to chemical and enzymatic activities. The breakdown of fat, protein and carbohydrates of meat results in the development of off-odors, off-flavor and slim formation which make the meat objectionable for human consumption. It is, therefore, necessary to control meat … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 2 Nov 2011 · 54,854 accessesView PDFCite
