For many years, it has been known that when rats and mice are given a reduced amount of food, their life span is increased and they remain healthy and vigorous at advanced ages. What is the reason for this change in the usual pattern of
aging? The evidence is overwhelming that the life extension results
from a slowing of aging processes. And the factor responsible is
the decrease in caloric intake. The obvious question: How does this
factor work? A good question - and the reason that research on the
anti-aging action of caloric restriction is today one of the most
studied research areas in biological gerontology. For it is felt
that if the biological mechanisms of the anti-aging action of
caloric restriction can be uncovered, we would gain an
understanding of the basic nature of aging processes, which would,
in turn, yield possible interventions in human aging. This book
aims to provide the growing number of researchers in this field
(faculty, postdoctoral trainees, and graduate students) with a
detailed knowledge of what is known about caloric restriction
within the frame of gerontology, as well as insights on future of
this field.
The work described in this book is an excellent example of interdisciplinary research in systems biology. It shows how concepts and approaches from the field of physics can be efficiently used to answer biological questions and reports on a novel methodology involving creative computer-based analyses of high-throughput biological data. Many of the findings described in the book, which are the result of collaborations between the author (a theoretical scientist) and experimental biologists and between different laboratories, have been published in high-quality peer-reviewed journals such as Molecular Cell and Nature. However, while those publications address different aspects of post-transcriptional gene regulation, this book provides readers with a complete, coherent and logical view of the research project as a whole. The introduction presents post-transcriptional gene regulation from a distinct angle, highlighting aspects of information theory and evolution and laying the groundwork for the questions addressed in the subsequent chapters, which concern the regulation of the transcriptome as the primary functional carrier of active genetic information.
This book presents the current state of knowledge on the origin and differentiation of cell lines involved in the development of the vertebrate male and female gonads with particular emphasis on the mouse.

This book identifies and analyzes the genetic basis of bone
disorders in humans and demonstrates the utility of mouse models in
furthering the knowledge of mechanisms and evaluations of
treatments. The book is aimed at all students of bone biology and
genetics, and with this in mind, it includes general introductory
chapters on genetics and bone biology and more specific
disease-orientated chapters, which comprehensively summarize the
clinical, genetic, molecular genetic, animal model, functional and
molecular pathology, diagnostic, counselling and treatment aspects
of each disorder. Provides a common language for bone biologists and geneticists to discuss the development of bone cells and genetics and their interactions in the development of disease Researchers in all areas bone biology and genetics will gain insight into how clinical observations and practices can feed back into the research cycle and will, therefore, be able to develop more targeted genomic and proteomic assays For those clinical researchers who are also MDs, correct diagnosis (and therefore correct treatment) of bone diseases depends on a strong understanding of the molecular basis for the disease.
An overview of all the available literature on the various aspects of the regulation of the cardiovascular system`s function and physiology by the adrenergic neurohormonal system, i.e. the catecholamines norepinephrine and epinephrine. Although there are several books describing the adrenergic system`s biology, physiology and pharmacology, and also several excellent books on cardiovascular physiology and pathology, this book focuses exclusively on the interface of these two areas: cardiovascular regulation by the adrenergic system and how it affects cardiovascular diseases and their treatments. Each chapter describe the roles of the adrenergic system first in each cardiovascular cell type (cell type-by-cell type) and then in specific areas of cardiovascular physiology, such as in exercise and in cardiovascular metabolism. Finally, the book concludes with a chapter on the adrenergic system`s role in the currently very "hot" (in terms of scientific investigations) area of cardiovascular stem cell biology. The book covers the adrenergic system-specifically and exclusively in the heart and vessels. It is formatted by cardiovascular cell type-by-cell type manner, rather than in an organ-by-organ or in a disease-by-disease manner, as usually discussed in standard, conventional biomedical textbooks. The book also discusses the adrenergic system in novel, cutting-edge cardiovascular research areas, in which it has not been covered well so far (e.g. stem cells, exercise). These three areas constitute the most important assets of the book, which sets it apart from others in the field.
How does contemporary science contribute to our understanding about what it means to be women or men? What are the social implications of scientific claims about differences between ""male"" and ""female"" brains, hormones, and genes? How does culture influence scientific and medical research and its findings about human sexuality, especially so-called normal and deviant desires and behaviours? Gender and the Science of Difference examines how contemporary science shapes and is shaped by gender ideals and images. Prior scholarship has illustrated how past cultures of science were infused with patriarchal norms and values that influenced the kinds of research that was conducted and the interpretation of findings about differences between men and women. This interdisciplinary volume presents empirical inquiries into today's science, including examples of gendered scientific inquiry and medical interventions and research. It analyses how scientific and medical knowledge produces gender norms through an emphasis on sex differences, and includes both U.S. and non-U.S. cases and examples.

The discovery of vitamins in the early 1900s, their later chemical characterization and the clarification of pivotal metabolic functions are sequential aspects of a brilliant chapter in the history of modern nutritional sciences and medicine. The name, derived from "vital-amines", indicates their elementary metabolic key functions in human metabolism. Vitamins are truly families of compounds, which include precursors and various free and bound forms, all with individual roles in metabolism and function. A more recent approach therefore searches for the components, the understanding of their roles in physiology and pathology as well as looking for novel pharmacological applications. When used properly, vitamins are, indeed, "magical" substances. Due to their efficacy, they should therefore be regarded as drugs with effects and side effects to be weighted against each other. Today, it is not the previously fatal deficiency-associated diseases that are in the focus of interest, but rather the relation of suboptimal vitamin bioavailability to chronic disease. This is complicated by genetic susceptibility, lifestyle, and the presence or absence of health-compromising habits, such as smoking. In turn, the development and application of new and more sensitive and specific assays further enable us to look more closely into the many functions of vitamins. Water soluble vitamins are complex molecular structures and even today, many areas in vitamin biochemistry are not yet fully understood. Novel effects and functions of vitamins remain and continue to be discovered. This book presents most recent research results and fascinating new knowledge on the role and effects of the water soluble vitamins in man. Some of the most distinguished chemists, biochemists, biologists and clinicians have contributed valuable chapters sharing unexpected novel insights into the biochemistry, (epi)genetics, metabolism, and function of water soluble vitamins, with their potential for clinical applications. Thus, physicians, clinicians, scientists, researchers, epidemiologists. nutritional specialists and health professionals alike will find stimulating and fascinating new insight in the many roles that water soluble vitamins play in human health and disease.

"Our Genes, Our Choices: How Genotype and Gene Interactions Affect Behavior" explains how the complexity of human behavior, including concepts of free will, derives from a relatively small number of genes, which direct neurodevelopmental sequence. Are people free to make choices, or do genes determine behavior? Paradoxically, the answer to both questions is "yes," because of neurogenetic individuality, a new theory with profound implications. Author David Goldman uses judicial, political, medical, and ethical examples to illustrate that this lifelong process is guided by individual genotype, molecular and physiologic principles, as well as by randomness and environmental exposures, a combination of factors that we choose and do not choose. Written in an authoritative yet accessible style, the book
includes practical descriptions of the function of DNA, discusses
the scientific and historical bases of genethics, and introduces
topics of epigenetics and the predictive power of behavioral
genetics.
