Mitochondria: the cell powerhouse and nexus of stress
Mitochondrion, a sub-cellular organelle originated from primary endosymbiosis, plays a vital role in energy metabolism of eukaryotic cells. The transfer of electrons through the electron transport chain (ETC) to molecular oxygen accompanied by the extrusion of protons from the matrix generate an electrochemical gradient across the inner mitochondrial membrane (IMM) that is used for ATP synthesis by oxidative phosphorylation. Despite many aspects of ATP synthesis have been delineated, regulatory mechanisms responsible for energy synthesis and transfer still remain to be uncovered. In addition to energy function, mitochondria play a crucial role in cell metabolism under both physiological and ...
Creatine and Creatine Phosphate
Creatine and Creatine Phosphate: Scientific and Clinical Perspectives is an up-to-date summary of both the scientific and medical aspects of creatine and creatine phosphate metabolism and therapy.It covers in detail the basic biochemistry, bioenergetics and biophysics of these agents with particular emphasis on their role on the cardiovascular and muscle systems. Modern in vivo myocardial and skeletal muscle measurements are outlined, and the importance of the molecules in cardiovascular medicine, sport science and cardiac surgery are highlighted.This book is designed for those interested in the basic scientific background to creatine and creatine phosphate, and also for physicians treating or studying heart and vascular disease. The book will also be vital for sports scientists who wish to acquire a comprehensive knowledge of the molecule which is currently being promoted for performance and exercise programmes.
Discovering Life, Manufacturing Life
Francis BACON, in his Novum Organum, Robert BOYLE, in his Skeptical Chemist and René DESCARTES, in his Discourse on Method; all of these men were witnesses to the th scientific revolution, which, in the 17 century, began to awaken the western world from a long sleep. In each of these works, the author emphasizes the role of the experimental method in exploring the laws of Nature, that is to say, the way in which an experiment is designed, implemented according to tried and tested te- niques, and used as a basis for drawing conclusions that are based only on results, with their margins of error, taking into account contemporary traditions and prejudices. Two centuries later, Claude BERNARD, ...
The Chemical Reactions of Life
Presents an introduction to the biochemistry, describes the history of the science, and discusses chemical reactions found in plants and animals.
Examining Biochemical Reactions
Biochemical reactions, which facilitate metabolic and / or photosynthetic changes in each life form through the actions of enzymes, make all life possible. This insightful volume considers the various types, causes, and results of different reactions that operate at the cellular level and beyond to sustain biological activity. Readers will explore the early discoveries of the first biochemists and trace these developments and their impact to the latest advancements in and applications of biochemistry, ultimately leading to a deeper understanding of life on Earth.
Creatine Kinase
Creatine kinases and arginine kinases are an historical model in enzymology. They belong to the large family of phosphagen kinases which transfer a phosphoryl group from ATP to a nitrogen atom within a guanidinium group to form that was called by the early muscle physiologists a 'phosphagen'. These compounds and the enzymes that catalyse their formation and use are present in cells with important and rapidly fluctuating energy requirements.
Detection of Mitochondrial Diseases
In October 1995, the 1st Colloquium on Mitochondria and Myopathies in Halle/Saale was organized in Halle/Saale by the editors of this focused issue. The meeting took up what might be called an East German tradition: from 1976 to 1990 Andreas Schmidt organized seven clinically orientated Colloquia on Myology in Jena, and from 1974 to 1990 a series of twelve Colloquia on Mitochondria focused on basic research aspects was arranged by Wolfgang Kunz in Magdeburg. At those meetings, East Germany was a mediator between East European, West European and American scientists. In continuation of this tradition, scientists from more than 17 countries working on mitochondria as neurologists, biochemists, ...
