Research ArticleOpen accessIn the abstractSustainable Management of Effluents from Small Piggery Farms in MexicoJ.L. de Victorica-Almeida, M. Galván-García, R. Ayala-RuizIn Mexico, pig farming is the third most important livestock activity due to its contribution to the total meat production. However, it is estimated that around 38% of pig farms dispose their wastewaters without any treatment directly into the nation’s water bodies, which in turn has a severe impact in the environment. One reason for not treating is the high … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,369 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHIV-1-Specific CTL Recognizing a Scarce Epitope Are Not Suppressed by HIV-1 Protease InhibitorsOtto O. YangHIV-1-protease inhibitors have received growing attention as agents that can affect proteases in human proteasomes, with potentially deleterious effects for HIV-1-specific cellular immunity. Studying the antiviral activity of HIV-1-specific CTL that recognize an epitope that is presented at limiting concentrations on infected cells, we find that several HIV-1 protease inhibitors do not affect their function. These data indicate that these … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 7,019 accessesView PDF Cite
