Hamza, Sayel Daoud, Waleed HamzaCadmium (Cd) is an environmental and industrial cumulative pollutant that most affects many organs specially the liver. The protective effect of Spirulina, filamentous blue green algae, on Cd – induced oxidative stress and hepatotoxicity was evaluated in male rats. Oral administration of water extract of Spirulina for seven days followed by an acute toxic dose of Cd (3.5 mg kg … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 2 · 30 Jun 2006 · 11,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractCortisol Response Mediates HIV-1-Related Cognitive Deficits Among Injecting Drug AbusersRaymond L. Ownby, Drenna Waldrop-Valverde, Adarsh M. Kumar et al.The cortisol response is an important measure of the endocrine activity to environmental challenges and has been related to cognitive function and mood. Previous studies have shown that the cortisol response to stress is dysregulated in persons with HIV-1 infection. Since cortisol is neurotoxic and its levels have been related to cognitive dysfunction in various disorders, it is possible that … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,762 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractPhysical Basis of Magnetic Resonance Spectroscopy and its Application to Central Nervous System DiseasesNicolás Fayed, Salvador Olmos, Humberto Morales, Pedro J. ModregoMagnetic Resonance Spectroscopy is based on the chemical shift property of the atom nuclei when a magnetic field is applied. This technique offers invaluable information about living tissues with special contribution to the diagnosis and prognosis of the central nervous system diseases. Concentration of several metabolites can be assessed in a reproducible manner by means of modern clinical scanners. N-acetyl-aspartate … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoftware Process Modeling Using Role and CoordinationAtil Fadila, Ghoul Said, Bounour NoraThe term software process joins all activities that have to be achieved in order to develop software. It has been shown that modeling such processes is difficult and expensive task. It's confirmed by diversity of software processes modeling approaches which are however, not satisfactory. This study deals with an area of growing importance and presents a role- and coordination- based … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,575 accessesView PDFCite

Research ArticleOpen accessIn the abstractSupporting Tools to Simplify the Navigation Process over the WebChabane Khentout, Mahieddine Djoudi, Lamri DouidiWe Navigation through the Web has problems of positioning and space-temporal reference marks. Therefore, it’s necessary to design some computer-aided tools to help the user to position himself in space and time during a navigation session. The user is provided with a map of visited sites, thus giving an explicit representation of virtual space. Various levels of visualization are set … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a High-Performance IP Switching ArchitectureHattab Guesmi, Belgacem Bouallegue, Ridha Djemal, Rached TourkiIn this study we present the architecture for use in high-performance switching networks with support quality of service (QoS) guarantees. Quality of services guarantees in terms of delay, through-put and loss rate can be provided by using mechanism's support like scheduling and buffer management at switching architecture in packet switching networks. Our architecture is based on a new data structure … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,812 accessesView PDFCite
