The zebrafish is the most important fish model in developmental and genetic analyses. This book contains 19 review articles covering a broad spectrum of topics, from development to genetic tools. The contents range from early development, the role of maternal factors and gastrulation, to tissue differentiation and organogenesis, such as development of the organizer, notochord, floor plate, nervous system, somites, muscle, skeleton and endoderm. The genetic tools cover morpholino knock-down, transgenics, fish cloning, transposons and genome evolution. The book also includes two chapters on genome mapping and embryonic stem cells in medaka, another important model fish. Summarizing the state-of-the-art studies of the zebrafish model and focusing on the molecular aspects of development, this book is a valuable reference for students learning the basic aspects of the zebrafish model, and for researchers seeking resources in zebrafish research.
The zebrafish embryo has now been well established as an organism of choice for the genetic and cell biological basis of vertebrate development. Large-scale forward genetic screens together with reverse genetic tools have resulted in a flood of new information on the regulation of vertebrate development. Furthermore, the unique transparency of the zebrafish embryo allows unprecedented access to cells and tissues and many important discoveries on gene function have already been made using live imaging techniques in this organism. This book successfully brings together state-of-the-art methodologies of live imaging, such as the use of fluorescence correlation spectroscopy (FCS), that will be u...

This book provides a comprehensive overview of ZIC-family research. Part1 summarizes the ZIC family in animal evolution and development and presents an overall picture of the ZIC family gene structure in eumetazoan animals, providing an evolutionary hypothesis and reviewing the studies on the role of ZIC family proteins in developmental processes for each animal model. Part 2 shows that the ZIC family are the causative genes for developmental disorders, and discusses the role of the ZIC family in stem cell biology. It also presents studies on the ZIC family in the medical biology field. This interdisciplinary book is a valuable resource not only for those people directly involved in ZIC-family-related research, but also researchers in diverse research fields who are interested in the latest advances in biology and medicine.
Does the field of evolution differ from other sciences? The author, a reviewer for a major medical journal, scrutinized hundreds of scientific references in evolutionary literature, adopting the same standards used for studies submitted for medical publication. The data show that there are two types of evolution, microevolution and macroevolution, with a clear boundary between them based upon the presence and absence of empirical evidence, respectively. The surprising results show that there is a universal disconnect between the data and the conclusions that claim to show the larger changes of macroevolution. The author reveals patterns of deviations from standard scientific methods in these...

The brain functions within an internal environment that is determined and controlled by morphological structures and cellular mechanisms present at interfaces between the brain and the rest of the body. In vertebrates these interfaces are across cerebral blood vessels (blood-brain barrier) choroid plexuses (blood-cerebrospinal fluid barrier) and pia-arachnoid. There is a CSF-brain barrier in the neuroepithelium lining the ventricular system that is only present in embryos. There is now substantial evidence that many brain barrier mechanisms develop early and that in some cases they are functionally more active and even more specialized compared to adult barriers. Therefore barriers in develo...
An examination of a decade and a half of political controversy, ethical debate, and scientific progress in stem cell research. After a decade and a half, human pluripotent stem cell research has been normalized. There may be no consensus on the status of the embryo—only a tacit agreement to disagree—but the debate now takes place in a context in which human stem cell research and related technologies already exist. In this book, Charis Thompson investigates the evolution of the controversy over human pluripotent stem cell research in the United States and proposes a new ethical approach for “good science.” Thompson traces political, ethical, and scientific developments that came toge...
Since the 1990s, internationally-supported peacebuilding interventions have become increasingly prominent. Activities focusing on rule of law and security institutions are a key component of this agenda. Despite increasing calls for more rigorous analysis of the impact of peacebuilding interventions, conceptual advances have been limited. There is little clarity on what is working, what is not, and why. This SSR Paper seeks to address this gap by mapping relevant approaches and methodologies to measuring impact. It examines how international actors have approached these questions in relation to support to rule of law and security institutions in complex peacebuilding environments. Most significantly, the paper demonstrates that measuring impact is not only feasible but necessary in order to maximise the effectiveness of major international investments in this field.
Fluorescent proteins are intimately connected to research in the life sciences. Tagging of gene products with fluorescent proteins has revolutionized all areas of biosciences, ranging from fundamental biochemistry to clinical oncology, to environmental research. The discovery of the Green Fluorescent Protein, its first, seminal application and the ingenious development of a broad palette of fluorescence proteins of other colours, was consequently recognised with the Nobel Prize for Chemistry in 2008. Fluorescent Proteins II highlights the physicochemical and biophysical aspects of fluorescent protein technology beyond imaging. It is tailored to meet the needs of physicists, chemists and biologists who are interested in the fundamental properties of fluorescent proteins, while also focussing on specific applications. The implementations described are cutting-edge studies and exemplify how the physical and chemical properties of fluorescent proteins can stimulate novel findings in life sciences.
