Research ArticleOpen accessIn the keywordsMechanisms of Anti-Cancer Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Vernonia amygdalina (V. amygdalina) has been shown to have cancer cell inhibition and cytotoxic effects. Approach: This study discusses the multi-faceted and multi-linked mechanisms by which cancer tissue inhibition and destruction is achieved by V. amygdalina leaf extract and powder (subsequently called V. amygdalina Extract). Cancer cell inhibition by V. amygdalina is suggested to occur through inhibition of … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 26 Oct 2011 · 9,090 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAntioxidant Activity of Brown Algae Sargassum species Extract from the Coastline of Java IslandSiti A. Budhiyanti, Sri Raharjo, Djagal W. Marseno, Iwan Y.B. LelanaThe coastlines with rocky shores at Java Island Indonesia, Gunung Kidul (Yogyakarta) and Jepara (Central Java), have abundant resources of brown algae Sargassum sp. Little effort, however, has been made to explore the antioxidant potential of the algae harvested from these area. Tropical brown algae have proven to produce a very effective antioxidant defence system due to the strong UV … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 30 Aug 2012 · 9,901 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Incidence of Disorder-Promoting Amino Acids in the Amino Terminus of Mature Proteins in Bacillus subtilisGuangqiang Wang, Yining Dong, Haiqin Chen et al.Problem statement: Exported polypeptides are usually synthesized as preproteins which are composed with mature domains and the signal peptides. The foreign proteins are usually inefficiently secreted by the aid of signal peptides. Although we know that the mature protein played an important role in the protein export process, we do not know what properties of the mature domains are critical … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 2 Feb 2012 · 8,255 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural Changes in the Ileum of White BALB/C Mice Experimentally Infected with Salmonella hadarAfaf Abdulrahman Yousif, Maan M. Neima AL-NaqeebProblem statement: Recently, Salmonella hadar has been isolated and identified from goat in Iraq. The purpose of the present study was to investigate the ultrastructural changes in the ileum epithelial cells of mice experimentally infected with Salmonella hadar. Approach: The white BALB/c mice inoculated orally with Salmonella enterica serovar hadar strain and their ileums were examined by transmission electron microscopy … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,113 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural Evidences of Hepatitis B Infection in Human Liver Biopsies Disclose Complex Assembly and Morphogenesis Pathways for Hepatitis B VirusViviana Falcon, Ivon Menéndez, Nelson Acosta-Rivero et al.Despite of recent advances on acknowledge of hepatitis B virus (HBV) structure and biology, little is known about the morphogenesis and release of virions. In this study, the ultrastructural analysis of HBV components in liver biopsies from chronically HBV-infected patients disclosed complex assembly and morphogenesis pathways for HBV. HBV core (HBcAg) and surface (HBsAg) antigens were specifically identified in all … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,091 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCholesterol Metabolism in Brain and Skin Fibroblasts from Sarda Breed Sheep With Scrapie-resistant and Scrapie-susceptible GenotypesAlessandra Pani, Claudia Abete, Claudia Norfo et al.Scrapie is a fatal spongiform encephalopathy of sheep, a transmissible form of prion disease caused by neuronal accumulation of the aberrantly conformed prion protein (PrPsc). Currently, no ante-mortem diagnostic tests are available to detect this untreatable disease in the pre-clinical stage, thus making difficult to control its spread. Recent evidence suggests that the production of PrPsc can be modulated by … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 7,257 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEmetine produce Entamoeba histolytica Death by Inducing a Programmed Cell DeathJ.D. Villalba-Magdaleno, R. Rojas, C. Gómez et al.Amoebiasis is a major public health problem in tropical and subtropical countries. Although a number of antiamoebic agents are used for its treatment and the molecular targets of these drugs have been identified, the biochemical and physiological mechanisms that produce trophozoite death are little known. The present study dates the in vitro induction of programmed cell death (PCD) in E. … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,211 accessesView PDF Cite
