Degradation of heme involves its conversion to biliverdin by heme oxygenase followed by reduction of biliverdin to bilirubin by biliverdin reductase. There is ample evidence for the pleiotropic functions of biliverdin reductase in cell signaling and regulation of gene expression. This enzyme plays a major role in glucose uptake and the stress response. Bilirubin has been shown to behave as a "double-edged sword". It can exert either cytotoxic or cytoprotective effects, depending on the blood and/or tissue concentration of its free fraction, the nature of the target cell or tissue, and the cellular redox state. Its antioxidant effect is the basis for the proposed cardioprotective effect of relatively low blood concentrations of bilirubin in humans with moderate hyperbilirubinemia. This Special Topic forum is intended to serve as a platform for updating information and presenting advances in basic and clinical research in the above and related subjects.
At the workshop held in Leverkusen on December 1, 1993, Professor Dr. Stanislav Kazda was honored on the occasion of his retirement for his scientific contributions and his involvement in drug development in our company, Bayer AG. In a recent article by Eugene Garfield (Current ContentslLife Sciences 36:3-15, 1993), what most of us participating in this workshop have supposed for years was confirmed: that Kazda is one of the leading scientific authors in academia worldwide. In the said survey of citations of biomedical research articles, Kazda is number 29 in terms of actual impact, individual ~itations, and total number of published manuscripts (and this only covers the time period from 198...
The main effect of calcium channel blockers is the blockade of calcium entry into cells through voltage operated calcium channels. This volume gives a comprehensive overview of the different classes of CCBs and their various effects. It covers historical development, pharmacology, clinical aspects, and perspectives. All chapters are written by Prof. T. Godfraind, a world leading expert in the field.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
