Research ArticleOpen accessIn the keywordsUncommon Toxicologic Profile at Toxic Doses of CPI-613 (an Agent Selectively Alters Tumor Energy Metabolism) in Rats and Minipigs Reflects Novel MechanismClaudia Maturo, King C. Lee, Robert Rodriguez, Robert ShorrProblem statement: CPI-613 is a novel anticancer agent and the toxicological profile has not been assessed. Accordingly, the objective of these studies was to thoroughly evaluate the Toxicokinetic (TK) effects of CPI-613 in rats and to compare the toxicological profile of rats to minipigs to determine if there were differences between the two animal species. Approach: These studies involved assessments … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 4 · 13 Jun 2011 · 9,584 accessesView PDF Cite

Research ArticleOpen accessIn the abstractColor Doppler Evaluation of Isovolumetric Relaxation Time and of Signals Arising from Axons of the Median Nerve as a Means to Evaluate Mitochondrial Functionality in the Context of Immunotherapy of Cancer and Chronic Conditions Associated with Mitochondrial DysfunctionStefania Pacini, Marco RuggieroReactive Oxygen Species (ROS) arising from the disruption of mitochondrial respiration act as endogenous mutagens and tumor promoters. When production of ROS exceeds the capacity of DNA repair mechanisms, random mutations and aneuploidy ensue, thousands of genes become unbalanced and genetic/epigenetic chain reactions lead to progressive aneuploidy with only two outcomes: karyotypes so altered that are not viable or karyotypes … …American Journal of Immunology, Vol. 15, Issue 1 · 12 Oct 2019 · 9,700 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInhibition Effect of Walnut Leaf Polysaccharide on HepG2 Cells in vitroShuqing Yang, Haifang Xiao, Shuyan Yu et al.In this study, the effect of Walnut Leaf Polysaccharides (WLP) on human liver tumor HepG2 cells was investigated. The results showed that WLP had dose-dependent and time-dependent inhibitory effects on HepG2 cell viability. Typical apoptosis characteristics were observed in WLP-treated HepG2 cells through 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethyl-benzimidazolyl-carbocyanine iodide (DAPI) staining and Acridine Orange (AO)/Ethidium Bromide (EB) dual staining. Meanwhile, significant decrease in Mitochondrial … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 29 Oct 2019 · 7,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeroin-Induces Differential Protein Expression by Normal Human Astrocytes (NHA)Jessica L. Reynolds, Supriya D. Mahajan, Donald Sykes, Madhavan P.N. NairHeroin use is postulated to act as a cofactor in the neuropathogenesis of human immunodeficiency virus (HIV-1) infection. Astrocytes, integral components of the CNS, are reported to be susceptible to HIV-1 infection. Upon activation, astrocytes release a number of immunoregulatory products or modulate the expression of a number of proteins that foster the immunopathogenesis of HIV-1 infection. However, the role … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,267 accessesView PDF Cite
