Download or read book Drugs During Pregnancy and Lactation written by H. Garbis and published by Elsevier Science. This book was released on 2001-12-21 with total page 1300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The care of pregnant women presents one of the paradoxes of modern medicine. Women usually require little medical intervention during an (uneventful) pregnancy. Conversely, those at high risk of damage to their own health or that of their unborn require the help of appropriate medicinal technology, including drugs. Accordingly, there are two classes of pregnant women, the larger group requires support but not much intervention, while the other needs the full range of diagnostic and therapeutic measures applied in any other branch of medicine. This book presents the current state of knowledge about drugs in pregnancy. In each chapter information is presented separately for two different aspects of the problem seeking a drug appropriate for prescription during pregnancy, and assessing the risk of a drug when exposure has already taken place. Practising clinicians who prescribe medicinal products to women who are, or who may become, pregnant, will find this volume an invaluable reference.

Download or read book Electrostatic Accelerators written by Ragnar Hellborg and published by Springer Science & Business Media. This book was released on 2005-04-21 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrostatic accelerators are an important and widespread subgroup within the broad spectrum of modern, large particle acceleration devices. They are specifically designed for applications that require high-quality ion beams in terms of energy stability and emittance at comparatively low energies (a few MeV). Their ability to accelerate virtually any kind of ion over a continuously tunable range of energies makes them a highly versatile tool for investigations in many research fields including, but not limited to, atomic and nuclear spectroscopy, heavy ion reactions, accelerator mass spectroscopy as well as ion-beam analysis and modification. The book is divided into three parts. The first part concisely introduces the field of accelerator technology and techniques that emphasize their major modern applications. The second part treats the electrostatic accelerator per se: its construction and operational principles as well as its maintenance. The third part covers all relevant applications in which electrostatic accelerators are the preferred tool for accelerator-based investigations. Since some topics are common to all types of accelerators, Electrostatic Accelerators will also be of value for those more familiar with other types of accelerators.

Download or read book Host and Microbe Adaptations in the Evolution of Immunity written by Larry J. Dishaw and published by Frontiers Media SA. This book was released on 2019-12-31 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of metazoans has been accompanied by new interfaces with the microbial environment that include biological barriers and surveillance by specialized cell types. Increasingly complex organisms require increased capacities to confront pathogens, achieved by co-evolution of recognition mechanisms and regulatory pathways. Two distinct but interactive forms of immunity have evolved. Innate immunity, shared by all metazoans, is traditionally viewed as simple and non-specific. Adaptive immunity possesses the capacity to anticipate new infectious challenges and recall previous exposures; the most well-understood example of such a system, exhibited by lymphocytes of vertebrates, is based on somatic gene alterations that generate extraordinary specificity in discrimination of molecular structures. Our understanding of immune phylogeny over the past decades has tried to reconcile immunity from a vertebrate standpoint. While informative, such approaches cannot completely address the complex nature of selective pressures brought to bear by the complex microbiota (including pathogens) that co-exist with all metazoans. In recent years, comparative studies (and new technologies) have broadened our concepts of immunity from a systems-wide perspective. Unexpected findings, e.g., genetic expansions of innate receptors, high levels of polymorphism, RNA-based forms of generating diversity, adaptive evolution and functional divergence of gene families and the recognition of novel mediators of adaptive immunity, prompt us to reconsider the very nature of immunity. Even fundamental paradigms as to how the jawed vertebrate adaptive immune system should be structured for “optimal” recognition potential have been disrupted more than once (e.g., the discovery of the multicluster organization and germline joining of immunoglobulin genes in sharks, gene conversion as a mechanism of somatic diversification, absence of IgM or MHC II in certain teleost fishes). Mechanistically, concepts of innate immune memory, often referred to as “trained memory,” have been realized further, with the development of new discoveries in studies of epigenetic regulation of somatic lineages. Immune systems innovate and adapt in a taxon-specific manner, driven by the complexity of interactions with microbial symbionts (commensals, mutualists and pathogens). Immune systems are shaped by selective forces that reflect consequences of dynamic interactions with microbial environments as well as a capacity for rapid change that can be facilitated by genomic instabilities. We have learned that characterizing receptors and receptor interactions is not necessarily the most significant component in understanding the evolution of immunity. Rather, such a subject needs to be understood from a more global perspective and will necessitate re-consideration of the physical barriers that afford protection and the developmental processes that create them. By far, the most significant paradigm shifts in our understanding of immunity and the infection process has been that microbes no longer are considered to be an automatic cause or consequence of illness, but rather integral components of normal physiology and homeostasis. Immune phylogeny has been shaped not only by an arms race with pathogens but also perhaps by mutualistic interactions with resident microbes. This Research Topic updates and extends the previous eBook on Changing Views of the Evolution of Immunity and contains peer-reviewed submissions of original research, reviews and opinions.

Download or read book The Cell Biology of Stem Cells written by Eran Meshorer and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem cells have been gaining a lot of attention in recent years. Their unique potential to self-renew and differentiate has turned them into an attractive model for the study of basic biological questions such as cell division, replication, transcription, cell fate decisions, and more. With embryonic stem (ES) cells that can generate each cell type in the mammalian body and adult stem cells that are able to give rise to the cells within a given lineage, basic questions at different developmental stages can be addressed. Importantly, both adult and embryonic stem cells provide an excellent tool for cell therapy, making stem cell research ever more pertinent to regenerative medicine. As the title The Cell Biology of Stem Cells suggests, our book deals with multiple aspects of stem cell biology, ranging from their basic molecular characteristics to the in vivo stem cell trafficking of adult stem cells and the adult stem-cell niche, and ends with a visit to regeneration and cell fate reprogramming. In the first chapter, “Early embryonic cell fate decisions in the mouse”, Amy Ralson and Yojiro Yamanaka describe the mechanisms that support early developmental decisions in the mouse pre-implantation embryo and the current understanding of the source of the most immature stem cell types, which includes ES cells, trophoblast stem (TS) cells and extraembryonic endoderm stem (XEN) cells.

Download or read book Biology and therapeutic potential of brown adipose tissue written by Patrick Seale and published by Frontiers E-books. This book was released on 2013-06-03 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brown adipose tissue (BAT) has long been recognized as a key thermogenic tissue in eutherian mammals. Brown fat cells contain large numbers of highly specialized mitochondria that oxidize fat and carbohydrate to produce heat. This metabolic inefficiency is due to the presence of Ucp1 in the inner mitochondrial membrane of brown fat cells which dissociates the electrochemical gradient from ATP production. BAT presumably evolved to protect animals against hypothermia in response to cold exposure. However, energy expended by BAT has the added benefit of counteracting obesity and associated metabolic disease, at least in rodents. A very large number of studies have consistently shown that mice carrying increased amounts of active brown fat are lean and healthy. Until recently, it was generally believed that the amount of brown fat tissue was negligible in healthy adult humans. However, PET imaging studies have refuted this notion, and revealed the existence of active BAT in most, if not all, adult humans. Notably, there is a very strong inverse correlation between the amount of activated BAT and fatness in humans. Moreover, activated brown fat is lost with ageing, which also correlates with tendency to gain weight. The field must now address whether variation in brown fat activity is a cause or consequence of weight gain. Brown fat cells are localized in discrete depots of BAT and are also found as clusters interspersed in white fat tissues. The prevalence and function of these so-called “brite” (brown in white) cells in humans remains unknown. The development of strategies to increase the amount and/or activity of brown fat may hold exciting prospects for the treatment of obesity and its associated health consequences. In this Research Topics issue, we would propose to examine the following areas related to brown fat biology: 1. Development of brown and “brite” cells (including: historical/evolutionary perspective, transcriptional pathways, developmental origins) 2. Pathways that influence brown fat cell development (BMP7, TZDs, Prostaglandins, FGF21) 3. Activation of brown fat - focus on sympathetic and sensory innervation (signaling by beta-adrenergic receptors, nerve-fat connections 4. Brown fat thermogenesis in response to cold, diet and hibernation 5. Brown fat in humans including: human brown fat precursors, methods for imaging, factors that influence prevalence, relationship between body mass/obesity and amount of brown fat. 6. Brown fat mitochondria including mechanism of uncoupling (Ucp1 history/structure/function, mitochondrial biogenesis.
