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 · 6,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractAction of Calciotropic Hormones on Bone Metabolism-Role of Vitamin D3 in Bone Remodeling EventsCatharine Andresen, Ellen Olson, Chudy I. Nduaka et al.Vitamin D3 is known to have immunosuppressive effects that can be beneficial for treatment of immune disorders and transplant rejection, however therapeutic application is limited due to hypercalcemia and hypercalcuria. The goal of our studies was to explore both the acute and steady state effects of vitamin D3 on bone remodeling as potential limiting factors to broader use of vitamin … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 8,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,442 accessesView PDFCite
