Research ArticleOpen accessIn the abstractEffects of Bacillus subtilis 'PB6' (ATCC - PTA 6737) on Clostridium difficile Associated Diarrhea (CDAD) and Inflammatory Bowel Disease (IBD) in Animal ModelsEric Peys, Jerry Varghese, Ponusami Suresh et al.The administration of probiotic bacteria is emerging as a potential means of preventing the onset or recurrence of Clostridium difficile associated diarrhea (CDAD) and of attenuating inflammatory activity and preventing relapses in inflammatory bowel disease (IBD). We evaluated the efficacy of Bacillus subtilis 'PB6' (ATCC - PTA 6737) in a hamster model of antibiotic-induced CDAD and in a rat model … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,097 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTribochemical Performance of Cell-treated Nickel MatrixBing Shi, Thomas B. Kuhn, Hong Liang, Lawrence K. DuffyNickel (Ni) has been studied as a biomaterial for a long time because of the unique mechanical properties and corrosion resistance. In this study, the frictional properties and wettability of Ni under dry and lubricated conditions, including cell treatment, were compared in order to investigate its tribological performance under conditions similar to that in a human body. The wettability was … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,477 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMorpho-physiological Differences of the Spermatheca of Attini Ants (Hymenoptera: Myrmicinae)Gabriela Ortiz, Maria Izabel Camargo-MathiasThe insect's spermatheca store the spermatozoa from the time of copulation until the fertilization of the eggs and consists of a sac, usually associated to glands. The ant species Atta laevigata, Atta sexdens sexdens, Atta sexdens piriventris, Acromyrmex coronatus and Cyphomyrmex muelleri are considered pests, as they cause economics losses to several crops. The spermatheca of these species were examined … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 4 · 31 Dec 2006 · 7,583 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Hybrid Fuzzy Neural Networks for the Detection of Tumors in Medical ImagesN. Benamrane, A. Freville, R. NekkacheIn this study, we propose an approach to detect suspect zones or tumors in medical images. The idea is to define with precision the existence of different kinds of lesions using a hybrid system, which combines Fuzzy Neural Networks and Expert System. After applying a method of image segmentation to extract regions (by region growing algorithm or by mathematical morphology … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,873 accessesView PDF Cite
