As the active interface of the most biologically intimate connection between two living organisms, a mother and her fetus, the placenta is crucial to human evolution and survival. Michael L. Power and Jay Schulkin explore the more than 100 million years of evolution that led to the human placenta and, in so doing, they help unravel the mysteries of human life's first moments. Starting with some of the earliest events that have influenced the path of placental evolution in mammals and progressing to the specifics of the human placenta, this book examines modern gestation within an evolutionary framework. Human beings are a successful species and our numbers have increased dramatically since our earliest days on Earth. However, human fetal development is fraught with poor outcomes for both the mother and fetus that appear to be, if not unique, far more common in humans than in other mammals. High rates of early pregnancy loss, nausea and vomiting during pregnancy, preeclampsia and related maternal hypertension, and preterm birth are rare or absent in other mammals yet not unusual in humans. Power and Schulkin explain why this apparent contradiction exists and address such topics as how the placenta regulates and coordinates the metabolism, growth, and development of both mother and fetus, the placenta’s role in protecting a fetus from the mother’s immune system, and placental diseases. In the process, they reveal the vital importance of this organ—which is composed mostly of fetal cells—for us as individuals and as a species. -- Errol R.

Neuroscientists investigate the mechanisms of spatial memory. Molecular biologists study the mechanisms of protein synthesis and the myriad mechanisms of gene regulation. Ecologists study nutrient cycling mechanisms and their devastating imbalances in estuaries such as the Chesapeake Bay. In fact, much of biology and its history involves biologists constructing, evaluating, and revising their understanding of mechanisms. With In Search of Mechanisms, Carl F. Craver and Lindley Darden offer both a descriptive and an instructional account of how biologists discover mechanisms. Drawing on examples from across the life sciences and through the centuries, Craver and Darden compile an impressive toolbox of strategies that biologists have used and will use again to reveal the mechanisms that produce, underlie, or maintain the phenomena characteristic of living things. They discuss the questions that figure in the search for mechanisms, characterizing the experimental, observational, and conceptual considerations used to answer them, all the while providing examples from the history of biology to highlight the kinds of evidence and reasoning strategies employed to assess mechanisms. At a deeper level, Craver and Darden pose a systematic view of what biology is, of how biology makes progress, of how biological discoveries are and might be made, and of why knowledge of biological mechanisms is important for the future of the human species.

How We Live And Why We Die The Secret Lives Of Cells

Acclaimed biologist Lewis Wolpert eloquently narrates the basics of human life through the lens of its smallest component: the cell. Everything about our existence-movement and memory, imagination and reproduction, birth, and ultimately death-is governed by our cells. They are the basis of all life in the universe, from bacteria to the most complex animals. In the tradition of the classic Lives of a Cell, but with the benefit of the latest research, Lewis Wolpert demonstrates how human life grows from a single cell into a body, an incredibly complex society of billions of cells. Wolpert goes on to examine the science behind topics that are much discussed but rarely understood—stem-cell research, cloning, DNA, cancer—and explains how all life on earth evolved from just one cell. Lively and passionate, this is an accessible guide to understanding the human body and life itself.

The complete textbook on complementary therapies in maternity care, this book addresses how midwives and other birth professionals can use or advise on complementary therapies for pregnant, labouring and new mothers. Almost 90% of women may be using complementary therapies during pregnancy and birth, and increasingly midwives and doulas incorporate therapies into their care of women, so it is vital that they and other professionals in the maternity care field are aware of safe and appropriate use based on contemporary evidence. Therapies covered include acupuncture, herbal medicine, homeopathy, aromatherapy, reflexology, yoga, massage and hypnosis. This complete guide to complementary therapies in pregnancy and childbirth covers safety, effectiveness, evidence, benefits and risks, legal, ethical and professional issues based on accurate and up-to-date research.

Reproductive and Developmental Toxicology, Second Edition, is a comprehensive and authoritative resource that provides the latest literature on this complex subject with a primary focus on three core components—parent, placenta, and fetus—and the continuous changes that occur in each. Enriched with relevant references describing every aspect of reproductive toxicology, this revised and updated resource addresses the totality of the subject, discussing a broad range of topics, including nanoparticles and radiation, gases and solvents, smoking, alcohol and drug abuse, and metals, amongst others. With a special focus on placental toxicity, this book is the only available reference to connect the three key risk stages, also including discussions on reproductive and developmental toxicity in domestic animals, fish, and wildlife. Completely revised and updated to include the most recent developments in the field, the book is an essential resource for advanced students and researchers in toxicology, as well as biologists, pharmacologists, and teratologists from academia, industry, and regulatory agencies. Provides a complete, up-to-date, integrated source of information on the key risk stages during reproduction and development Includes new chapters covering significant developments, such as dose-response assessment for developmental toxicity, juvenile toxicity, and neural tube defects, as well as emerging science, such as stem cell application, toxicoproteomics, metabolomics, endocrine disruption, surveillance and regulatory considerations, and risk assessment Offers diverse and unique in vitro and in vivo toxicity models for reproductive and developmental toxicity testing in a user-friendly format that assists in comparative analysis

Biomedical scientists are the foundation of modern healthcare, from cancer screening to diagnosing HIV, from blood transfusion for surgery to food poisoning and infection control. Without biomedical scientists, the diagnosis of disease, the evaluation of the effectiveness of treatment, andresearch into the causes and cures of disease would not be possible. The Fundamentals of Biomedical Science series has been written to reflect the challenges of practicing biomedical science today. It draws together essential basic science with insights into laboratory practice to show how an understanding of the biology of disease is coupled to the analyticalapproaches that lead to diagnosis. Assuming only a minimum of prior knowledge, the series reviews the full range of disciplines to which a Biomedical Scientist may be exposed - from microbiology to cytopathology to transfusion science. A core text in the Fundamentals of Biomedical Science series, Biomedical Science Practice gives a comprehensive overview of the key laboratory techniques and professional skills that students need to master. The text is supported throughout with engaging clinical case studies, written to emphasizethe link between theory and practice, providing a strong foundation for beginning biomedical science students.
