Ergonomics Guidelines and Problem Solving
1st Edition
Volume 1
A. Mital + 2 more
English
There is an urgent need to disseminate ergonomics "know-how" to the work place. This book meets that need by providing clear guidelines and problem solving recommendations to assist the practitioner in decisions that directly protect the health, safety and well-being of the worker.The guidelines have evolved from a series of symposia on Ergonomic Guidelines and Problem Solving. Initially experts in each area selected were asked to write draft guidelines. These guidelines were circulated to participants at the symposia and to other experts for review before being comprehensively revised. In some instances these guidelines cannot be considered complete but it is important now to put some recommendations forward as guidelines. It is hoped that as new research emerges each guideline will be updated.Each guideline has been divided into two parts. Part I contains the guidelines for the practitioner and Part II provides the scientific basis or the knowledge for the guide. Such separation of the applied and theoretical content was designed to facilitate rapid incorporation of the guide into practice.The target audience for this book is the practitioner. The practitioner may be a manager, production system designer, shop supervisor, occupational health and safety professional, union representative, labor inspector or production engineer. For each of the guidelines, relevant practitioners are described.Topics covered include work space design, tool design, work-rest schedules, illumination and maintenance.
Genetic Aberrancies and Neurodegenerative Disorders
1st Edition
Volume 3
M.P. Mattson
English
Genetic Aberrancies and Neurodegenerative Disorders presents critical reviews and emerging findings concerning the roles of genetic mutations and polymorphisms in the pathogenesis of a range of neurological disorders including Alzheimer's and Parkinson's diseases, trinucleotide repeat disorders, stroke, epilepsy and others. This volume, written by leading experts, brings together fundamental information concerning the roles of inherited traits in the pathogenesis of different neurodegenerative disorders. In addition to providing a catalogue of the known genetic alterations that are linked to specific neurodegenerative disorders, the chapters detail the current state of understanding of the cellular and biochemical mechanisms whereby the genetic aberrancies lead to neuronal dysfunction and degeneration. The emerging picture of each disorder, painted by pathological, biochemical and molecular brushes, suggests that they share key mechanisms including increased levels of oxidative stress, perturbed ion homeostasis, mitochondrial dysfunction and apoptotic proteolytic cascades. The existence of specific molecular defects provides the opportunity to design experiments that can establish the precise pathogenic mechanism of a specific mutation or genetic risk factor. The value of this approach is exemplified by recent studies of how mutations in Cu/Zn-superoxide dismutase cause amyotrophic lateral sclerosis and how presenilin mutations result in early-onset Alzheimer's disease. A theme developed among the different chapters is that events that occur during aging predispose neurons to genetic aberrancies that promote degenerative cascades, and that specific genetic defects exert their influence on particular populations of neurons in a disorder-specific manner. The chapters in this volume will stimulate readers to generate new hypotheses concerning the pathogenic mechanisms of genetic aberrancies that can be experimentally tested.
Dynamic Surface Tensiometry in Medicine
1st Edition
Volume 8
V.N. Kazakov + 4 more
English
Human biological liquids contain numerous low- and high-molecular weight surfactants. The human organism contains interfaces with enormous surfaces. The physicochemical and biochemical processes taking place at these interfaces are extremely important for the vital functions of the organism as a whole, and the interfacial properties may reflect peculiarities of age and sex, health and disease. The present book is the first attempt to systematically present the results of dynamic and equilibrium surface tensions measurements of serum and urine samples that were obtained from healthy humans of various sex and age, and to compare these results with measurements of biological liquids obtained from patients suffering from various diseases or with measurements of amniotic fluid obtained from women at various stages of pregnancy.Pulmonary medicine, especially neonatology, has systematically used interfacial tensiometry for studying pulmonary surfactant. In this particular area, significant progress was achieved in the treatment of diseases related to alterations of the lung surfactant system. We believe that, similar to the progress in pulmonary medicine attributed to surface chemical studies of lung surfactant, progress in other medical branches could be expected through studies of interfacial characteristics of other human biological liquids.For several years the authors of this book have been engaged in studies aimed at the improvement of the maximum bubble pressure method, resulting in the development of computer controlled tensiometers which are capable of measuring dynamic surface tensions within a wide range of surface lifetime. In addition to the measurement techniques, a correct interpretation and analysis of the tensiometric data obtained is extremely important. The kinetic theory of adsorption from solutions, and the theory of equilibrium adsorption layers of surfactant/protein mixtures provide the basis for both the choice of the most characteristic parameters of tensiograms and the analysis of the results. Some theoretical models describing the adsorption of proteins are presented in Chapter 1. The main theoretical and experimental issues related to the maximum bubble pressure technique as applied to biological liquids are presented in Chapter 2. A more detailed discussion of the differences of the various methods in use for measuring dynamic surface tension of biological fluids is provided in Chapter 3. Chapter 4 gives data from patients with kidney disease, Chapter 5 from patients with rheumatic diseases, Chapter 6 with pulmonary diseases, Chapter 7 with diseases of the central nervous system, and Chapter 8 with neoplasms.Dynamic interface tensiometry of human biological liquids is a fascinating new method which deserves a broad use for prospective studies of various diseases.
Phagocytosis: Microbial Invasion
1st Edition
Volume 6
S. Gordon
English
The present volume focuses on microbial invasion strategies of pathogen uptake. An accompanying volume (Vol. 5) in the series presents the phagocytic process from the viewpiont of the host cell. This field of study is growing rapidly after a somewhat slow start over recent decades. This collection of invited chapters attempts to reflect current research and brings together cell biologists, microbiologists, and immunologists wiht disthemes, hopefully like a symphony rather than a boring catalogue. It will be evident that editorial bias favors intracellular parasitism and medically important organisms. The neutrophil is far more than a supporting player to the macrophage and some attempt is made to remind the reader of some of its unique skills. To retain a manageable size, the emphasis is on relatively early events such as mutual recognition, cell entry, and response, rather than on longterm changes in gene expression by either host cell or pahtogen. Viruses are excluded not because of lack of importance but because of somewhat different research approaches, although it is becoming increasingly clear that large viruses (e.g. Vaccinia) and Listeria monocytogenes, share common strategies in invasion and intercellular spread.

1st Edition
Volume 5
H.T. Tien † + 1 more
English
This book summarizes the current status of research on bilayer lipid membranes (planar lipid bilayers and spherical liposomes). In addition to describing the properties of lipid bilayers and examining biomembrane phenomena, the book has two other objectives. The first is to present practical methods for the formation and study of lipid bilayers with either aqueous or metal-lipid bilayer interfaces. The second aim is to treat planar lipid bilayers as a new type of interfacial adsorption phenomena.The first nine chapters cover properties of biomembranes, basic principles of membrane biophysics, transport, electrochemistry, physiology, bioenergetics, and photobiology. Chapter 10 presents the following topics: lipid bilayers in medicine, supported lipid bilayers as sensors, a short discussion of liposomes, and solar energy transduction via semiconductor septum photovoltaic cells based on natural photosynthesis.

The significance, therefore, of the Studies in Natural Product Chemistry series, edited by Professor Atta-ur-Rahman, cannot be overestimated. This volume, in accordance with previous volumes, presents us with cutting-edge contributions of great importance.
Gap Junctions
1st Edition
Volume 30
E.L. Hertzberg
English
The objective in editing this volume was twofold: to provide a reasoned overview of the field as well as to furnish one that provided this overview within the context of the intellectual boundaries of those who initially attempted to define the purview of gap junction research. The latter objective has been realized by selecting the topics for review in this volume. The former objective was achieved by securing the cooperation of leaders in their fields as chapter co-authors.
Biological Psychiatry
1st Edition
Volume 14
Edward Bittar
English
It is now widely recognised that biological psychiatry is rapidly coming into its own. For over the last three decades dramatic advances in this young discipline have been made, all of which attest to the staying power of the experimental method. Those who made this revolution in knowledge happen are a breed of investigators availing themselves of the tools of molecular biology, pharmacology, genetics, and perhaps, above all, the technology of neuroimaging. The introduction of the interdisciplinary method of approach to the study of psychopathology had made it very clear that neuroimaging, as a set of techniques, is unique in that it is gradually providing us with evidence supporting Kraepelin's original view that mental illness is closely associated with abnormal changes in the brain.Broadly speaking, there are presently two structural techniques in neuroimaging - computed tomography and magnetic resonance imaging (MRI) - and three functional techniques - single photon emission tomography (SPECT), positron emission tomography and magnetic resonance imaging (fMRI). Through PET technology, for example, we have learned that, in early brain development, the primitive areas, mostly the brain stem and thalamus, are the first to show high activity in an infant. This is followed by the development of cortical areas by year one. Between the ages of four to 10, the cortex is almost twice as active in the child as in the adult. This information alerts us to what might happen in the way of trauma in abused children, especially those under the age of three. Child abuse increases the risk of physical changes, not only in the stress systems, but also in brain development (Glaser and Weissman). In addition to the difficult problem of post-traumatic stress disorder (PTSD), we have to take into account the possibility of other types of mental illness as the consequences of child abuse. These include depression, eating disorders, and drug and alcohol problems.The combination of PET and fMRI represents a more remarkable example of the power of neuroimaging since the two have made it feasible to map accurately in vitro identifiable cortical fields, or networks. In a landmark NIH investigation of human cortical reorganization (plasticity), persuasive evidence was brought forward showing that the process of learning as a motor task involves a specific network of neurons. These neurons occur in the cortical field that is responsible for that particular task. Such findings are important partly because they provide evidence supporting the current notion that labor in the cortex is divided among ensembles of specialized neurons that cooperate in the performance of complex tasks. Cooperation, then, in this, sense implies crosstalk among ensembles and that signals are both processed and retransmitted to neighbouring ensembles. To understand the workings of these ensembles, much better spatial and temporal resolution in functional brain mapping is required. This can be achieved with an NMR instrument whose magnet is 4.1 Tesla or more.
