Book Description
Somite development is a unique and important topic; unique because somitic mesoderm is the first tissue to become segmented, important because the somites - once established - exert a profound influence on other seg mental structures which form later. Somite development is of interest at a number of levels. In one aspect, demarcation of a specific number of somites and size regulation, it is a particularly intriguing example of embryonic pattern formation, 'especially in vew of its possible relation to homoeobox-controlled segmentation in insects. At another level, somite development has long been studied by compara tive anatomists, but only recently has new light been thrown on such sub jects as segmentation of the head, proposed in the 18th century by Goethe and now a live issue for developmental biologists. Somit es are simple when they first appear, but very complex structures arise from them. These include the vertebrae and the axial and other muscles and consequently there is a wealth of morphogenetic problems to be explored. Sometimes their morphogenesis is disturbed, by genetic or environ mental factors, and there are many clinical conditions which arise as a result.

Book Description
Building the Most Complex Structure on Earth provides readers with a basic biological education an easy and understandable introduction into a new epigenetic theory of development and evolution. This is a novel theory that describes the epigenetic mechanisms of the development and evolution of animals and explains the colossal evolution and diversification of animals from a new post-genetic perspective. Modern biology has demonstrated the existence of a common genetic toolkit in the animal kingdom, but neither the number of genes nor the evolution of new genes is responsible for the development and evolution of animals. The failure to understand how the same genetic toolkit is used to produce millions of widely different animal forms remains a perplexing conundrum in modern biology. The novel theory shows that the development and evolution of the animal kingdom are functions of epigenetic mechanisms, which are the competent users of the genetic toolkit. - Provides a comprehensive view of the epigenetic aspects of reproduction, development, and evolution. - Highly rigorous, but simple enough for readers with only a basic knowledge of biology.

Book Description
This is the first and only book, so far, to deal with the causal basis of evolution from an epigenetic view. By revealing the epigenetic "user" of the "genetic toolkit", this book demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theory with a host of examples from the most varied fields of biology, by emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. - Original and thought provoking--a radically new theory that overcomes the present difficulties of the theory of evolution - Is the first and only theory that uses epigenetic mechanisms and principles for explaining evolution of metazoans - Takes an integrative approach and shows a wide range of learning

Book Description
The success of Assisted Reproductive Technology is critically dependent upon the use of well optimized protocols, based upon sound scientific reasoning, empirical observations and evidence of clinical efficacy. Recently, the treatment of infertility has experienced a revolution, with the routine adoption of increasingly specialized molecular biological techniques and advanced methods for the manipulation of gametes and embryos. This textbook – inspired by the postgraduate degree program at the University of Oxford – guides students through the multidisciplinary syllabus essential to ART laboratory practice, from basic culture techniques and micromanipulation to laboratory management and quality assurance, and from endocrinology to molecular biology and research methods. Written for all levels of IVF practitioners, reproductive biologists and technologists involved in human reproductive science, it can be used as a reference manual for all IVF labs and as a textbook by undergraduates, advanced students, scientists and professionals involved in gamete, embryo or stem cell biology.

Book Description
In this Atlas I want to share with my fellow clinicians the fascina tion I experienced while discovering the marvels of embryonic development. Why haven't these marvels excited me before? I believe that the use of schemata and drawings or photographs of animal embryos, commonly used in textbooks of embryology, simply did not appeal to me as a clinician. Only actual photo graphs of human embryos can establish the bond necessary for interaction. Just imagine the excitement when you find out how many struc tures you can recognize in a 5-week-old embryo, barely measuring 1 cm in length. But our fascination does not stop here. The pro gression of changes taking place during the next 3 weeks is so rapid that at the time when the embryo measures 3 cm, all structures familiar to us are not only easily recognizable, but also already in their anatomical position. How can we hide our amazement when we realize that such a state of perfection is present in an embryo a bit longer than the distal phalanx of our little finger? At 8 weeks the embryonic period ends and the fetal one starts. Although the shape and the relative size of bones, joints, muscles, nerves, and vessels will undergo changes, the basic elements are all in place. This implies that major malformations must develop during the embryonic period.

Book Description
"This book provides a complete look at neonatal healthcare delivery. This edition includes discussions of contemporary topics of interest, such as informatics, genetics, global health, and family-centered care, which are vital to providers caring for neonates today. The case studies and the evidence-based practice dialogues at the end of each chapter provide great opportunities for further reflection. The book is useful to a wide audience in nursing, including undergraduate and graduate nursing students, practicing neonatal and pediatric nurses, and advanced practice nurses who care for neonates." Score: 92, 4 Stars.--Doody's Medical Reviews This 'classic' has been thoroughly updated to incorporate the most up-to-date research findings and strategies for providing cost-effective and evidence-based care. New chapters address emerging infections, the late preterm infant, and neonatal care from a global perspective. Included are updated neonatal care protocols and procedures, neuroprotective risk factors, new treatments, and new trends in developmental care. Text integrates the Institute of Medicine's (10M) five competencies, reflects the Affordable Healthcare Act and the Robert Wood Johnson and 10M report "The Future of Nursing." The text continues to provide neonatal care from a physiologic and pathophysiologic approach, with a major emphasis on nursing management at the bedside and advanced practice level. Each neonatal body system is presented, along with E-B interventions to assist in understanding the 'why' behind what is seen in the clinical area. Integrative management is threaded through the text along with extensive research findings to support practice strategies and rationales for sound clinical decision-making. Topics of recent interest include iatrogenic complications, neonatal pain, use of computers or other technology in neonatal care, and neonatal AIDS. Case studies enhance understanding of both common and rare neonatal conditions. New to the Fifth Edition: New chapters: emerging infections, the late preterm infant, and neonatal care from a global perspective Updated neonatal care protocols and procedures, neuroprotective factors, new treatment modalities and new trends in developmental care Tackles the UN Millennium Development Goals (MDGs) Addresses the expansion of the nurse's role in the US and worldwide Provides case studies that lead the reader through the identification, diagnosis, treatment, and evaluation of common and rare neonatal conditions
