Product Description
First published in 1989, this book acknowledges that new drugs, food additives and other compounds need to be carefully screened for toxic side-effects. The bulk of this study is devoted to the practical questions of ‘what toxicological studies should we perform?’ and ‘how should we perform them?’ Compounds which undergo toxicity testing may be conveniently categorised as those which are intended for administration to man and those which are not. The former include pharmaceuticals to be used medicinally or prophylactically and chemicals which are added to our food, drinks or medicine to improve their stability, appearance or palatability. Since it is on pharmaceuticals that the most comprehensive toxicological evaluations are generally performed, this book has been directed primarily towards to toxicological evaluation of potential new drugs. The principles and methodology of toxicological evaluation of other types of compounds are essentially similar.

A Practical Approach to Toxicological Investigations

Product Description
Whereas other fields continue to become more complex and specialized, physiology happily remains an area that can still be understood by thinking from first principles. However, given the increasing quantity of information available today, it is easy to become overly concerned with details and give in to the temptation to memorize rather than understand. In this concise book, the authors convey their enthusiasm for physiology and convincingly persuade the reader that with a sound understanding of principles, details often fall effortlessly into place. It is by no means an attempt to produce another comprehensive textbook. Instead, a broad overview of the subject is presented, covering areas that are not given the attention they deserve in other texts whilst purposely omitting those aspects where memorization is an unfortunate necessity.

Contents: Electrical Properties of Cells; Muscle as an Excitable Tissue; The Digestive System; The Respiratory System; The Circulatory System; The Kidney and Body Fluids; Integrative Physiology; Derivations and Theoretical Points.

There is a strong interest in transthyretin (TTR) in connection with protein evolution, medical and clinical research. Thus, this is an exciting time for experts in TTR research to come together to write a monograph covering both the basic and the clinical research into TTR.

Transthyretin is a protein found in human blood and cerebrospinal fluid. It is directly involved in the transport of thyroid hormones, and indirectly in that of retinol. These hormones are essential for normal growth and development, particularly that of the brain. Spontaneous and inherited diseases affecting transthyretin result in amyloidosis. More than 80 point mutations in transthyretin lead to a variety of illnesses. Liver transplants are the most common treatment, although much research is also being carried out in drug therapies.

The evolution of transthyretin has been extensively investigated – from humans to bacteria, invertebrate animals and plants. The structure of the protein has not changed, but its function has changed significantly. This is a most exciting example for the study of the evolution of protein structure-function relationships.

This monograph will bring the reader up to date on the latest developments and discoveries.

Recent Advances in Transthyretin Evolution, Structure and Biological Functions

Product Description
The volume offers insight into the key research topics that involve caspases. Leading experts from various areas of biology and medicine have compiled this volume so that both the novice and the professional will use this as the main reference for caspases for years to come. The reader will learn about the role of caspases in apoptosis signaling, inflammation and cancer therapy while being updated on the methodology used to study caspases and the efforts of pharmaceutical research in targeting caspases.

Caspases: Their Role in Cell Death and Cell Survival

Product Description
This book presents for the first time a view of a sensory system working in a different state-that of the sleeping brain. The auditory system is always “open” receiving information from the environment and the body itself (conscious and unconscious data). Even during sleep the auditory information is processed, although in a different way. This book draws information from evoked potentials, fMRI, PET, SPECT, lesions, etc., together with electrophysiological online data in order to depict how the auditory system single unit activity, recorded during sleep, revealed the possibility of sensory information participation in sleep processes.

* Presents diverse experimental viewpoints from the beginning of classical electroencephalography to the more recent imaging, single units, electro-magneto-encephalography studies, etc.
* Includes classic data as well as new data based in the existing literature and on the long scientific research lines (auditory and sleep) developed by the author and coworkers on this subject since 1963

Product Description

Almost a century and a half of study produced substantial progress in our understanding of glial cells and their development. As in other areas of science, major advances were associated with the discovery of new methods. These are summarized first. Most of this account describes development of glia in the CNS. We begin with astroglia because of their known presence and significance in early embryonic stages. Some of Åström’ s unpublished evidence is included in this section. After consideration of oligodendroglia, microglia and ependymal cells, we describe the development of Schwann cells, the glia found in the PNS.

In general, morphological observations of developing mammalian nervous tissues (mostly rodent) are emphasized; we have also tried to include findings relevant to cytodifferentiation, interactions, functions and regulation of developing glia. Of course, much has been learned about glial development by studying other species and a variety of experimental models, such as tissue culture systems, grafts and mouse mutants. Selected aspects of these subjects are also included.

This book reviews current understanding of normal muscle tone and how it differs in spastic, thixotropic and hypotonic patients. The book contains practical advice on measuring the postural system and will be of interest to pediatricians and also to physiologists involved in investigating muscle tone.

Muscles, Masses and Motion: The Physiology of Normality, Hypotonicity, Spasticity and Rigidity

Product Description
Strong pedagogy stresses understanding concepts over excessive detail. This emphasis on understanding the abstract concepts promotes comprehension and understanding over memorization. Art program uses photos and illustrations together to take students step-by-step from examinations of the larger body parts to the cellular and molecular level. Homeostasis and the interrelationship between body structure and function are emphasized with diagrams and concept maps.
