Buch. Zustand: Neu. Neuware - The super family of immunoglobulin related proteins also include the T cell receptors and the major histocompatibility complex (MHC), which, together with the receptors for immunoglobulins (the Fc receptors), are of fundamental importance in the processes of immunity. Volume 3 of 'Biomembranes' explores the structures and functions of the molecules involved in these important functions of the cell.

Buch. Zustand: Neu. Neuware - This is the third volume in a series on membrane protein transfer. Membrane protein transport underlies the topological disposition of many proteins within cells and it is this disposition that allows for the co-ordination of the central cellular processes, such as metabolism.

Buch. Zustand: Neu. Neuware - This volume is intended to complete the Cell Chemistry and physiology module. It is about how the traditional boundaries of cell chemistry and physiology are being erased by molecular biology. We do not think it necessary to elaborate on this theme, particularly since the body of core knowledge found in this volume brings us a stage closer to answering the question, 'what makes cell biology into a new discipline 'The first part of the volume deals with the chemistry of actin and myosin and is followed by chapters on cell motility, ATP synthesis in muscle, and contraction in smooth and skeletal muscle. Here the reader is immediately made aware of the contributions molecular biology is making to our understanding of the molecular mechanisms underlying muscle contraction. It is perhaps enough to point out that Huxley's concept of the cross-bridge cycle and generation of force can now be explained in molecular terms. Topics such as muscle fatigue and muscle disorders, as well as malignant hyperthermia are bound to arouse active learning in the student and set the stage for problem-based learning.Most medical students look askance at thermobiology. We think this is a mistake; hence, we have included a section dealing with this subject. This brings us to the chapter on the heat shock response, which at the very outset makes clear that many stressors besides heat are known to result in heat shock gene expression. Many of the heat shock proteins occur in unstressed cells and some of them behave as chaperones. These proteins also reach high levels in a wide range of diseases including neurodegenerative disorders. Whether certain diseases are the result of mutations in the heat shockgenes is not yet known. As will be appreciated, much of the work done in this field involved the use of cultured cells. Animal cells in culture are the subject of the last chapter.

Buch. Zustand: Neu. Neuware - Part of a series which covers areas of organic synthesis ranging from the latest developments in enantioselective methodologies, to reviews of updated chemical methods. The volumes are written by experts, who describe their own area of expertise, as well as those of their peers.

Buch. Zustand: Neu. Neuware - Some major aspects of these interactions, such as trophoblast function, myometrial contractility, and the endocrine-paracrine systems, are discussed in further chapters.

Buch. Zustand: Neu. Neuware - Volume 4 of 'Advances in Developmental Biology and Biochemistry 'consists of five chapters that review specific aspects of fly and mammalian development. In Chapter 1, Y. Mishina and R. Behringer discuss various aspects of Mullerian-inhibiting substance (MIS) in mammals, from a brief history of its discovery to recent studies of the MIS gene in transgenic and knock-out animals. In Chapter 2, C. Rushlow and S. Roth discuss the role of the 'dpp'-group genes in dorsoventral patterning of the 'Drosophila' embryo. In Chapter 3, M. Yip and H. Lipshitz discuss the terminal (asegmental termini) gene hierarchy of 'Drosophila' and the genetic control of tissue specification and morphogenesis. In Chapter 4, R. Bachvarova discusses induction of mesoderm and the origin of anterior-posterior polarity in the mouse embryo, using the frog embryo as a paradigm. In Chapter 5, P. Vogt discusses human Y chromosome function in male germ cell development.

Buch. Zustand: Neu. Neuware - The present volume continues the trend established in previous volumes in this series on 'Advances in Structural Biology'. As in the past, diverse topics of current importance relevant to the theme of the series are included in the fourth volume.

Buch. Zustand: Neu. Neuware - Interest in the concept of time has a long history and has been a topic of study for a wide range of investigators. No change can take place without specification of time. While philosophers and physicists have been intrigued by the concept of subjective perception of time and its relationship to real time, natural scientists have been concerned mainly with investigating time as a factor in understanding the behaviour of animals from the migratory habits of birds to the periodical breeding cycles. The immense bulk of temporal perception studies, the variety of approaches, methods of measurement and even terminology has led to a difficulty in reaching a global interpretation of the results.

Buch. Zustand: Neu. Neuware - This volume presents articles containing up-to-date expositions of work in the optics field. Topics covered include: transverse patterns in wide-aperture nonlinear optical systems; coherent population trapping in laser spectroscopy; and quantum phase properties of nonlinear optical phenomena.

Buch. Zustand: Neu. Neuware - Volumes 6 and 7 of the Collected Works are in turn related to the forthcoming Volume 10 which broadens the scope by presenting Bohr's applications of the complementarity argument beyond the domain of physics. Although each volume may be read independently, careful attention should be paid to the interrelationships between each volume in order to appreciate the subtlety of Bohr's continued elaboration and fine-tuning of his complementarity argument.
