Research ArticleOpen accessIn the abstractEssential Role of PKCδ in Apoptosis Induction of Mouse ThymocytesC. Lutz-Nicoladoni, T. Letschka, M. Leitges et al.The family of protein kinases C (PKCs) has been implicated in signal transmission leading to apoptosis induction and/or survival. These effects are cell type and tissue dependent. Numerous studies employing phorbol ester, a pleiotropic PKC activator, strongly implicated PKC in apoptosis induction of thymocytes. However, phorbol esters activate both, the conventional PKCs (PKCα, β, γ) as well as the novel … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,135 accessesView PDFCite

Research ArticleOpen accessIn the abstractBy-pass Devices as Effective Means of Protection from the Hydraulic HammerKhalid S. Al-RababaSwitching-off the parallel working pump units causes sudden discharge changes in parallel pipe lines, as a result of that hydraulic shocks takes place. The damping of these shocks can be achieved by the installation of the by-pass devices between the parallel lines of the piping system. The analytical calculations demonstrate that the reduction in hydraulic shocks reaches 40% and considerable … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,912 accessesView PDFCite
