Download or read book A Flexible System of Enzymatic Analysis written by Oliver Lowry and published by Elsevier. This book was released on 2012-12-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Flexible System of Enzymatic Analysis is a multipurpose manual of laboratory methods that offers a systematic scheme for the analysis of biological materials from the level of the wholeorgan down to the single cell and beyond. It intends to guide the development of methods, the refinement of old ones, and the adaptation in general of methods to almost any scale of sensitivity. This manual is organized into three parts: a general section, one on quantitative histochemistry, and an appendix containing information that may be useful to have at the bench. The general section is comprised of nine chapters that focus on properties of the pyridine nucleotides, kinetics, and glassware, as well as on improvement, modification, adaptation, trouble shooting, and development of methods. This part also describes the preparation of tissues for analysis, the enzymatic cycling methods, and a compendium of 36 metabolite assays. The quantitative histochemistry section is comprised of four chapters that include information on the preparation of frozen-dried material and dissection of samples for analysis; the fishpole balance for weighing samples; and the generalities of analysis with emphasis on the ""oil well technique."" This book will be useful to novices as well as experts who are familiar with other analytical styles.
Download or read book Enzymatic Analysis written by Janet V. Passonneau and published by Springer Science & Business Media. This book was released on 2008-02-07 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymatic Analysis: A Practical Guide is a multipurpose manual of laboratory methods. It offers a systematic scheme for the analysis of biological materials from the level of the whole organ down to the single cell and beyond. It is intended as a guide to the development of new methods, to the refinement of old ones, and to the adaptation in general of methods to almost any scale of sensitivity. As some may realize, the book is a sequel to A Flexible System of Enzymatic Analysis, originally published in 1972. The major changes, other than an appropriate interchange of authors, consist of a wholly new chapter of methods and protocols for measuring enzymes, the addition of 13 new entries in the metabolite chapter, and a much superior chapter on enzymatic cycling. With considerable nostalgia, we have switched from DPN and TPN to NAD and NADP nomenclature, which no doubt will make Otto Warburg turn over in his grave. The incentives for the methodology in this book came from the rigorous demands of quantitative histochemistry and cytochemistry. These demands are specificity, simplicity, flexibility, and, of course, sensitivity—all likewise desirable attributes of methods for other purposes. The specificity is provided by the use of enzyme methods. Simplicity is achieved by leading all reactions to a final pyridine nucleotide step.
Download or read book Neurochemistry of the Vestibular System written by Alvin J. Beitz and published by CRC Press. This book was released on 1999-12-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to quantify the sensory stimuli and resulting behavioral responses has enabled researchers over the past thirty years to gain an in-depth understanding of the physiological processes and neural pathways involved in the control of eye and head movements and posture. However, the molecular mechanisms and neurochemical processes that underlie neurotransmission of the vestibular and oculomotor pathways have begun to be defined only during the past decade. The first book available on this topic, Neurochemistry of the Vestibular System covers the proliferation of new information stemming from the technical advances in the areas of molecular biology and neurochemistry. It analyzes the recent developments in areas that relate to the neurochemical organization of the hair cells in the inner ear, the vestibular nerve, the vestibular nuclear complex, and central afferent and efferent vestibular projections. The book also identifies future directions for research in the areas of neurotransmitters, second messengers, transcription factors, and molecular mechanisms involved with both normal vestibular function and compensation.

Download or read book The Physiological Properties of Plant Protoplasts written by Paul-Emile Pilet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for the p~esent book arose from a 3-day seminar which I organized in March 1984 for young research workers in plant physiology. Participants came from several universities of the French-speaking part of Switzerland and speakers from Basel, Mtinchen, Nottingham, Perpignan, Regensburg, Sheffield, Toulouse, Yale, ZUrich ... and Lausannne. The theme of the seminar was chosen from the range of research fields of our Institute. Meanwhile, feeling it was important to bear in mind that some of our hearers were not specialists in the chosen topic, I wished to pro vide a subject that would be of scientific, methodological and epistemologi cal interest. The critical analysis of the structural and functional characteristics of plant protoplasts exactly met these criteria. There exists ample material for discussion of the techniques of protoplast preparation, methods used in morphological, biological and biochemical studies, and for the comparison of protoplasts with the cells from which they are obtained.
Download or read book Biochemistry of Characterised Neurons written by Neville N. Osborne and published by Elsevier. This book was released on 2013-10-22 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry of Characterised Neurons provides a report on the progress made in the analysis of the biology of specific neurons in the central nervous system. This book emphasizes the biochemical, morphological, and functional aspects of characterized neurons, including ways and sophisticated techniques of isolating them. This publication is divided into 11 chapters. The first chapter evaluates the relevance of working with single neurons. Chapters 2 to 6 discuss specific, characterized, invertebrate neurons containing one of the putative neurotransmitter substances. Chapter 7 deals with the biochemistry of a unique vertebrate (Torpedo) cholinergic system that enables pure cholinergic neuronal cell bodies and endings to be analyzed separately. The sensitive radiochemical procedures used to analyze transmitter substances and transmitter enzymes, and how they can be adapted to map the distribution of transmitters in individual neurons of Aplysia, are discussed in Chapter 8. Chapter 9 describes methods for the analysis of specific cells in the retina, while Chapters 10 and 11 focus on the analysis of proteins within defined neurons. This text is beneficial to biochemists and students interested in analyzing neurons.

Download or read book Urinary Enzymes written by Klaus Jung and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest and research in urinary enzymology were incited about three decades ago by reports that urinary enzymes are elevated in diseases of the kidney and urinary tract. Of the more than 40 hydrolases, oxidoreductases, transferases, and lyases identified in human and animal urine, only ten or so are being used as diagnostic indicators. Recognition of the quantitative distribution of enzymes in the various anatomical and functional parts of the nephron and advances in our understanding of the handling of proteins by the kidney have made it possible to associate urinary enzyme activity patterns with physiological and pathophysio logical functions of the nephron. Confidence in the diagnostic value of urinary enzymes is not unanimous among clinicians and among scientists. The main reason for the difference in opinion may well be that the variability in data exceeds the variability one is accustomed to in the diagnostic enzymology of blood plasma enzymes. In contrast to plasma enzymes, which are protected by an "enzyme friendly" milieu, enzymes released into the urine encounter an "enzyme hostile" environ ment: no or little protective protein, variable pH, variable volume, variable metabolite and salt concentrations, variable concentrations of enzyme in hibitors. Through advances in methodology some of these factors can now be controlled; standardization of urine collection periods and preanalytical treat ment are as important as optimization of assay methods.
Download or read book Micromethods in Molecular Biology written by Volker Neuhoff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on practical experience and is therefore written as a prac tical manual. The fore-runners of the book were the manuals of the first and second EMBO-Courses on "Micromethods in Molecular Biology" which were held in G6ttingen in the spring of 1970 and the autumn of 1971. This book may serve as a manual not only for the participants of the third EMBO-Course to be held in G6ttingen in autumn 1973, but also for all experimenters who are interested in using micromethods. It must be emphasized from the outset that this book is conceived as a "cook book" and not as a monograph which attempts to revue the literature on micromethods critically. The methods described here in detail are performed routinely in the authors' laboratories and include all the practical details necessary for the successful appli cation of the micromethods. There are many other sensitive and excellent micro methods which are not included in this book, because the authors feel that in a "cook book" only methods for which they have personal experience and profi ciency should be described. Some readers may feel that the title promises more than the present contents of this book; however, if sufficient interest is shown in this volume, it may be possible to remedy such deficiencies in future editions.

Available in PDF, EPUB and Kindle. Book excerpt: The recent worldwide explosion of interest in enzymes as cata lysts in industrial processes has arisen primarily because of the potential of major innovative advances which have taken place over the last two decades, foremost among these being novel methods of enzyme immobilization and affinity chromatography for rapid enzyme purification. This interest is now being further stimulated by the remarkable commercial success of several enzyme-based industrial processes, particularly the production of high-fructose syrup in the U. S. and amino acid production in Japan. With the initiation of these and other processes, together with the readying for commercial ization of several other enzyme-based operations, interest has ex panded in other areas in which enzymes may playa useful role, particularly in medicine and analytical chemistry. The development of this technology has required the cooperative efforts of practi tioners of several disciplines, primarily chemical engineers, bio chemists and other life scientists. Indeed, from this cooperation is arising the new interdisciplinary field of Enzyme Engineering. To stimulate communication, information exchange and advance ment of knowledge in this new field on an international level the Engineering Foundation, through the efforts of Lemuel B. Wingard, Jr. , initiated in 1971 a series of international conferences on Enzyme Engineering to be held biannually. The first two conferences were held in Henniker, New Hampshire, in the summers of 1971 and 1973, respectively, while the third conference, from which these proceedings derived, was held in August 1975 in Portland, Oregon.
Download or read book Regulation of Hepatic Metabolism written by K. Jungermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The liver is an exceptionally complex and diverse organ that functions both as an exocrine and an endocrine gland. It secretes bile, which contains many con stituents in addition to bile salts, and it synthesizes and releases many substances in response to the body's demands, including prohormones, albumin, clotting factors, glucose, fatty acids, and various lipoproteins. It has a dual blood supply providing a rich mixture of nutrients and other absorbed substances via the portal vein and oxygen-rich blood via the hepatic artery. This functional heterogeneity is accompanied by cellular heterogeneity. The liver contains many cell types including hepatic parachymal cells, Kiipffer cells, Ito cells, and endothelial cells. The most abundant cell type, the parenchymal cells, are biochemically and structurally heterogeneous. The cells in the oxygen-rich areas of the portal triad appear more dependent on oxidative metabolism, whereas those around the central vein (pericentral, perivenous, or centrolobular areas) are more dependent upon an anaerobic mechanism. Throughout this volume the latter three terms are used synonymously by various authors to indicate the five to eight layers of cells radiating from the central vein. Structural and metabolic heterogeneity of hepatic parenchymal cells has been demonstrated by a variety of approaches, including histochemical, ultra structural, and ultramicrobiochemical studies. This microheterogeneity is linked to the physiological functions of the liver and its response to injurious substances.

Download or read book Microchemical Analysis of Nervous Tissue written by Neville N. Osborne and published by Elsevier. This book was released on 2013-10-22 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microchemical Analysis of Nervous Tissue focuses on the use of microbiochemical methods in the analysis of nervous tissue, with emphasis on those related to the study of amines, amino acids, phospholipids, and proteins. Special attention is paid to the choice of biological material and the various procedures used for the isolation by dissection of defined components of the nervous system. Comprised of 10 chapters, this volume begins with an overview of microprocedures used in neurochemistry, followed by a discussion on the importance of choosing the biological material for microanalysis. The isolation of nervous tissue for analysis is then considered, with particular reference to invertebrate neurons; cell components from fresh, "fixed," freeze-dried, and frozen impregnated tissue; and discrete areas of nervous tissue. Subsequent chapters describe some instruments and glassware used in microprocedures, along with the applications of such procedures; general techniques used in microprocedures; microdetermination of phospholipids as well as amines and amino acids as dansyl derivatives; and microelectrophoresis of proteins. This book will be of interest to molecular biologists, microbiologists, physiologists, and neurochemists.
