The book concludes with approaches for the integration of this technology in safety evaluation studies, and an outlook on how toxicogenomics and complementary technologies can reframe the current risk assessment paradigm.

Women are contributing to disciplines once the sole domain of men. Field biology has been no different. The history of women field biologists, embedded in a history largely made and recorded by men, has never been written. Compilations of biographies have been assembled, but the narrative-their story-has never been told. In part, this is because many expressed their passion for nature as writers, artists, collectors, and educators during eras when women were excluded from the male-centric world of natural history and science. The history of women field biologists is intertwined with men's changing views of female intellect and with increasing educational opportunities available to women. Given the preponderance of today's professional female ecologists, animal behaviorists, systematists, conservation biologists, wildlife biologists, restoration ecologists, and natural historians, it is time to tell this story-the challenges and hardships they faced and still face, and the prominent role they have played and increasingly play in understanding our natural world. For a broader perspective, we profile selected European women field biologists, but our primary focus is the journey of women field biologists in North America. Each woman highlighted here followed a unique path. For some, personal wealth facilitated their work; some worked alongside their husbands. Many served as invisible assistants to men, receiving little or no recognition. Others were mavericks who carried out pioneering studies and whose published works are still read and valued today. All served as inspiration and proved to the women who would follow that women are as capable as men at studying nature in nature. Their legacy lives on today. The 75 female field biologists interviewed for this book are further testament that women have the intellect, stamina, and passion for fieldwork.

Oxidative damage appears to play a central role in the development of a wide range of tissue pathology, including neurodegenerative disease, drug side-effects, xenobiotic toxicity, carcinogenesis, and the aging process, to name just a few. Because of the centrality of oxidative processes to normal and abnormal tissue function, it has become imperative to develop appropriate analytical techniques to facilitate the quantitation of significant reactants. Without advances in methodology, corresponding advances in our knowledge of underlying biochemical events will be necessarily limited. Drs. Hensley and Floyd have done an outstanding job of assembling the work of world-class experts into Methods in Biological Oxidative Stress. The contributors have presented concise, yet thorough, descriptions of the state-of-the-art methods that any investigator working in the field needs to access. Mannfred A. Hollinger v Preface Free radicals and reactive oxidizing agents were once ignored as biochemical entities not worth close scrutiny, but are now recognized as causes or contributing factors in dozens, if not hundreds, of disease states. In addition, free radical metabolisms of xenobiotics have become increasingly important to pharmacologists. Accordingly, the need has arisen to accurately quantify reactive oxygen species and their byproducts. Methods in Biological Oxidative Stress is practical in scope, providing the details of up-to-date techniques for measuring oxidative stress and detecting oxidizing agents both in vitro and in vivo. The contributors are recognized experts in the field of oxidative stress who have developed novel strategies for studying biological oxidations.

This book is intended as an overview at an undergraduate or early university level and describes the effects of spaceflight at cellular and organism levels. Past, current, and future research on the effects of gravity - or its absence - and ionizing radiation on the evolution, development, and function of living organisms is presented in layman's terms by researchers who have been active in this field. The purpose is to enlighten science and non-science readers to the benefits of space biology research for conducting basic and applied research to support human exploration of space and to take advantage of the space environment as a laboratory for scientific, technological, and commercial research. The first chapters present an overview of the major focuses of space research in biology, as well as the history and the list of animals and plants that have flown in space to date.

This book is addressed to students, researchers and academics who have barely heard of the emerging young science of Biosemiotics, and who want to know more about it. Written by many of the fielda (TM)s major contributors, it provides a highly qualified introduction to Biosemiotics and illustrates the most recent views in its background and development.

Combining research approaches from biology, philosophy and linguistics, the field of Biosemiotics proposes that animals, plants and single cells all engage in semiosis a" the conversion of objective signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behavior and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life.

Drawing on an international expertise, the book details the history and study of biosemiotics, and provides a state-of-the-art summary of the current work in this new field. And, with relevance to a wide range of disciplines a" from linguistics and semiotics to evolutionary phenomena and the philosophy of biology a" the book provides an important text for both students and established researchers, while marking a vital step in the evolution of a new biological paradigm.

Marcello Barbieri is University Professor of Embryology at the University of Ferrara, Italy, President of the Italian Association for Theoretical Biology and Editor-in-Chief of the Journal of Biosemiotics.

Toby K. Eisenstein Symposium Committee Chairperson Temple University School of Medicine Philadelphia, Pennsylvania 19140 This symposium is the thirteenth biennial clinical microbiology program sponsored by the Eastern Pennsylvania Branch of the American Society for Microbiology in cooperation with the Philadelphia area medical schools and the Bureau of Laboratories of the Pennsylvania Department of Health. This year a generous contribution from Merck, Sharp and Dohme has helped to make the program a reality. The subject matter for this symposium represents an attractive spectrum of medical, biological and molecular approaches to the practical solution of a public health prob1em--name1y, prevention of infection with the hepatitis B virus. The symposium may be unique in that it focuses on a product which was first marketed less than three months ago, but included in the program are presen tations on two new approaches to hepatitis B vaccine production which may replace the one which is newly unveiled. The rapidity of progress in our present era of biological research is indeed astonishing."

This detailed volume explores the most recent methodologies and applications of stable isotope labeling by amino acids in cell culture (SILAC). With the development of new technologies in the field of mass spectrometry and bioinformatics, SILAC-based methods have become the first tool of choice in quantitative proteomics either on its own or in combination with other more recently developed approaches, which is elucidated in the chapters of this book. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, SILAC: Methods and Protocols serves as an ideal guide for researchers working in the area of functional proteomics and other aspects of protein science.

A knowledge of how plants have responded to environmental change in the past is our principal source of evidence for predicting how they might respond to the new environments of the future and a knowledge of past climates may enable us to assess more clearly the human contribution to the climatic changes of the future. This book aims to present the results of investigations into the history of the world's plant cover over the last 65 million years, not the methods by which these results have been achieved, and to document a selection of published accounts, both general and specific, for further reading. The book is organized into four main sections, dealing successively with the tenet that modern plant distributions and communities have been moulded by long-term environmental change, the nature of global environmental change over the last 65 million years, the ways in which plants and plant communities have responded to environmental change, and the global history of forest, dryland and coldland communities over the last 65 million years. The final chapter considers the future.

During the last two decades, structural equation modeling (SEM) has emerged as a powerful multivariate data analysis tool in social science research settings, especially in the fields of sociology, psychology, and education. Although its roots can be traced back to the first half of this century, when Spearman (1904) developed factor analysis and Wright (1934) introduced path analysis, it was not until the 1970s that the works by Karl Joreskog and his associates (e. g., Joreskog, 1977; Joreskog and Van Thillo, 1973) began to make general SEM techniques accessible to the social and behavioral science research communities. Today, with the development and increasing avail ability of SEM computer programs, SEM has become a well-established and respected data analysis method, incorporating many of the traditional analysis techniques as special cases. State-of-the-art SEM software packages such as LISREL (Joreskog and Sorbom, 1993a, b) and EQS (Bentler, 1993; Bentler and Wu, 1993) handle a variety of ordinary least squares regression designs as well as complex structural equation models involving variables with arbitrary distributions. Unfortunately, many students and researchers hesitate to use SEM methods, perhaps due to the somewhat complex underlying statistical repre sentation and theory. In my opinion, social science students and researchers can benefit greatly from acquiring knowledge and skills in SEM since the methods-applied appropriately-can provide a bridge between the theo retical and empirical aspects of behavioral research."
