The sodium of animal cell membranes converts the chemical energy obtained from the hydrolysis of adenosine 5' -triphosphate into a movement of the cations Na + and K + against an electrochemical gradient. The gradient is used subse quently as an energy source to drive the uptake of metabolic substrates in polar epithelial cells and to use it for purposes of communications in excitable cells. The biological importance of the sodium pump is evident from the fact that be tween 20-70% of the cell's metabolic energy is consumed for the pumping pro cess. Moreover, the sodium pump is an important biological system involved in regulatory processes like the maintenance of the cells' and organism's water me tabolism. It is therefore understandable that special cellular demands are han dled better by special isoforms of the sodium pump, that the expression of the sodium pump and their isoforms is regulated by hormones as is the activity of the sodium pump via hormone-regulated protein kinases. Additionally, the sodium pump itself seems to be a receptor for a putative new group of hormones, the endogenous digitalis-like substances, which still have to be defined in most cases in their structure. This group of substances has its chemically well known coun terpart in steroids from plant and toad origin which are generally known as "car diac glycosides". They are in medical use since at least 200 years in medicine in the treatment of heart diseases.

This unique volume provides an integrated overview of the subject of monovalent cations, specifically aimed at students and researchers. It is divided into two parts: the first deals with the processes by which monovalent cations are transported across biological membranes; the second deals with the processes that are affected by changes in intracellular cations. Each chapter describes in simple biochemical terms the interaction between one or more monovalent cations and a particular biological system of importance to current understanding of body function in health and disease. This useful publication is invaluable to students and researchers in biochemistry, physiology, neurology, pharmacology, anesthesiology, cardio-pulmonology, hematology, laboratory medicine, endocrinology, gastroenterology, internal medicine, psychiatry, urology, biomedical physics and medical nutrition.

Biological processes are driven by complex systems of functionally interacting signaling molecules. Thus, understanding signaling molecules is essential to explain normal or pathological biological phenomena. A large body of clinical and experimental data has been accumulated over these years, albeit in fragmented state. Hence, systems biological approaches concomitant with the understanding of each molecule are ideal to delineate signaling networks/pathways involved in the biologically important processes. The control of these signaling pathways will enrich our healthier life. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities. This encyclopedia presents 350 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike During past years, there were multiple databases to gather this information briefly and very partially. Amidst the excitement of these findings, one of the great scientific tasks of the coming century is to bring all the useful information into a place. Such an approach is arduous but at the end will infuse the lacunas and considerably be a streamline in the understanding of vibrant signaling networks. Based on this easy-approach, we can build up more complicated biological systems.

One of the most fascinating aspects of alkaliphiles is their ability to maintain pH homeostasis under extreme environmental conditions. This work provides a treatment of alkaliphilic microbiology, supported by molecular studies on the genetics of alkaliphilic "Bacillus" strain. Genomic analysis of "Bacillus halodurans" C-125 has been started and the genes responsible for alkaliphily are described. In addition to a basic background of alkaliphiles, including discussions of cell structures, physiology and molecular biology, "Alkaliphiles" presents an analysis of extracellular enzymes. Research on numerous enzymes including alkaline proteases, starch-degrading enzymes, cellulases, mannan-degrading enzymes, and many others is described in depth with relevant industrial applications.
