Arnost Kotyk - Böcker

This volume introduces a summary of all the techniques used to estimate pH reliably. Emphasis is placed on the techniques that provide the most reliable and detailed data. The role of cell pH is explained with special emphasis on enzymology and membrane transport and bioenergetics. This book was written especially for molecular biologists, biochemists and biophysicists.

An indispensable guide for editors authors and reviewers who want to understand the scientific terms used in the widest variety of fields. Quantities Symbols Units and Abbreviations in Life Sciences provides easy access to universally accepted symbols units abbreviations and measures of quantity for your scientific communications in the life sciences. Drawing on the authority of the various nomenclatural committees of the many international societies in bioscience as well as on the editors of prestigious scientific journals and on eminent individuals active in scientific publishing Arnost Kotyk brings together the most up-to-date recommendations for using units symbols abbreviations and acronyms in the biosciences. The diverse scope of disciplines include biochemistry molecular biology medicine genetics immunology and virology plus appropriate sections on mathematics physics and chemistry. This book grants authors and editors the security of knowing that their work will enjoy a high level of understandability among their colleagues.Reference librarians will also find Quantities Symbols Units and Abbreviations in Life Sciences a valuable tool for translating unknown acronyms and abbreviations.

TO THE SECOND EDITION When preparing the manuscript for the original edition of this book we were only partly aware of the pace at which the field of membrane transport was developing and at which new ideas as well as new techniques would be applied to it. The fact is that some of the chapters are now outdated (e. g. , the one on the molecular aspects of transport) and many others require revision in the light of new information that has appeared in the past five years. However, it is also true that we overemphasized in the first edition certain points that now appear less important and underestimated the impact of certain others that have since assumed a position among the most forcefully discussed topics of membrane research. In making amends, it was thus thought useful to include the discussion of these latter problems both in the theoretical and in the comparative sections and, on the other hand, to omit some of the less topical subjects. There was a different reason for rewriting the section on kidney and for dropping the section on mito­ chondria. The help of an expert nephrologist was enlisted for improving chapter 24, while it was decided that mitochondria represent a special field both conceptually (being only subcellular particles) and methodologically (more indirect estimation techniques being involved than with whole cells or tissues) and that more adequate information can be found in treatises specializing in work with mitochondria.

It is not a particularly rewarding task to engage in writing a book on a subject which is undergoing a rapid and potentially revolutionary develop­ ment, but, on the other hand, the investigation of transport of substances into and out of cells has reached a stage of maturity or at least of self­ realization and this fact alone warrants a closer examination of the subject. No one will doubt at present that the movement-mostly by selective translocation-of substances, ranging from hydrogen ions to deoxyribo­ nucleic acids, across the cell-surrounding barriers represents one of the salient features of a living cell and that, if we are permitted to go so far, the cessation of the selective transport processes might be considered as the equivalent of cell death. Hardly anybody will question the premise that cell and tissue differentiation within the ontogenetic development of an organism is closely associated with properties of the outer cell face. Perhaps no serious scholar will attempt to refute the concept that mem­ branes with characteristic morphology and composition represent the ar­ chitectural framework for the whole cell. And probably no experienced biologist will raise objections to the belief that many physiological processes, like nervous impulse conduction and other electrical phenomena of cells and tissues or their volume changes, are associated with membrane-regulated shifts of ions and molecules.
