Signal Transduction in Cardiovascular System Health and Disease highlights the major contributions of different signaling systems in modulating normal cardiovascular functions and how a perturbation in these signaling events leads to abnormal cell functions and cardiovascular disorders.This title is volume 3 in the new Springer series, Advances in Biochemistry in Health and Disease.

In vitro and animal studies show that vanadate and other Because most cellular components contain hydroxyl and/or vanadium compounds increase glucose transport activity and phosphate groups, vanadate reacts as shown in eq. 1, and 2 normalize glucose metabolism [1-5]. Furthermore, these with a variety of metabolites. For example, the reaction of insulin-mimetic compounds can be administered orally. Vana- vanadate with the 2'-hydroxyl group of the cofactor NAD date enhances the phosphoprotein formation which is attrib- generates an NADP analog, NADV (path b) [22]. NADV is uted to either the activation of protein kinases or inhibition an excellent cofactor for enzymes such as glucose-6-phos- of protein phosphatases. Despite the interest in document- phate dehydrogenase, 6-phosphogluconate dehydrogenase, ing the effects of vanadate on protein kinases, most reports and alcohol dehydrogenase [22]. The presence ofNADV have used indirect methods and studies with purified kinases could affect the levels of reducing equivalents in the cell, im- show weak, if any, interaction of vanadate with kinases as portant in maintaining a normal glucose metabolism.This a group of enzymes (reviewed in Refs.

In 1996 the 75th anniversary of the discovery of insulin was celebrated at the University of Toronto, the scene of that discovery in 1921. This volume was stimulated by the scientific program which was staged at that time and brought together much of the world's best talent to discuss and analyze the most recent developments in our understanding of pancreatic function, insulin secretion, the interaction of insulin with its target tissues, the mechanism of insulin action at the cellular level, and the defects which underlie both Type I (insulin-dependent diabetes mellitus, IDDM) and Type II (noninsulin-dependent diabetes mellitus, NIDDM) forms of the disease. We have chosen to focus the present volume on work related to insulin action.

This textbook offers a unique insight into the theoretical and applied aspects of human development in relation to the cultural traditions of non-Western countries.Presented in a modular form, this comprehensive and thematic approach to lifespan development will help students develop an understanding of human development in varied Indian social contexts. Covering all stages of development including the development of self and personality, social understanding, human strengths, sustainable development, lifelong learning, and many more, the book highlights current research in these areas as well as provides learning objectives, points for reflection, web links, and a glossary.This book is an essential reading for undergraduate students of psychology, human development, and allied fields, as well as for postgraduates with an interest in studying human development in a non-Western context.
