Research ArticleOpen accessIn the abstractA Mathematical Modeling Approach to Characterize Hormesis, Caloric Restriction and Toxicity in Mortality Data from Toxicity StudiesPatricia J. NeafseyThe mortality of a population reflects the combined effects of natural aging with environmental insults (e.g. toxicant exposure, caloric restriction, over feeding, infections, etc.). No single endpoint, such as carcinogenesis, completely describes toxicant-induced effects in laboratory animals. Mathematical models of mortality and time-dependent exposure to toxicants can yield indices of net injury from all causes. With careful manipulation of diet … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrelation Between MMP-3, TIMP-3 Expression and Neuronal Apoptosis After Ischemia -Reperfusion Injury in RatesZi Xiaohong, Mutasem Abuhamed, Yuan Yi et al.Matrix metalloproteinases (MMPs) play a central role in many biological processes, such as embryogenesis, normal tissue remodeling, wound healing, and angiogenesis. How MMP3, TIMP3 expression and neuronal apoptosis (Fas, Fas-L and Bcl) may provide detrimental or beneficial actions during the injury and repair processes after cerebral ischemia-reperfusion injury in rates was studied. Adult rats underwent middle cerebral artery occlusion (MCAO) … …American Journal of Immunology, Vol. 3, Issue 2 · 30 Nov 2007 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite

Review ArticleOpen accessIn the abstractDNA Vaccination Associated with Eliminating Inheritance Risks during Embryo Development: A ReviewRia MargianaThe process of immunization using modified DNA is essential whenever scientists desire to trigger an artificial response in the host’s body to improve immunity. The use of DNA vaccines awakens the somatic cells of the host to produce antigens that will assist the body to prepare to fight infections through preventive measures triggered by the vaccines. These biological inventions have … …OnLine Journal of Biological Sciences, Vol. 16, Issue 2 · 26 May 2016 · 6,873 accessesView PDFCite
