Available in PDF, EPUB and Kindle. Book excerpt: We live in an aging world. Illnesses that are prevalent and cause significant morbidity and mortality in older people will consume an increasing share of health care resources. One such illness is depression. This illness has a particularly devastating impact in the elderly because it is often undiagnosed or inadequately treated. Depression not only has a profound impact on quality of life but it is associated with an increased risk of mortality from suicide and vascular disease. In fact for every medical illness studied, e.g. heart disease, diabetes, cancer, individuals who are depressed have a worse prognosis. Research has illuminated the physiological and behavioral effects of depression that accounts for these poor outcomes. The deleterious relationship between depression and other illnesses has changed the concept of late-life depression from a "psychiatric disorder" that is diagnosed and treated by a psychiatrist to a common and serious disorder that is the responsibility of all physicians who care for patients over the age of 60. This is the first volume devoted to the epidemiology, phenomenology, psychobiology, treatment and consequences of late-life depression. Although much has been written about depressive disorders, the focus has been primarily on the illness as experienced in younger adults. The effects of aging on the brain, the physiological and behavioral consequences of recurrent depression, and the impact of other diseases common in the elderly, make late-life depression a distinct entity. There is a compelling need for a separate research program, specialized treatments, and a book dedicated to this disorder. This book will be invaluable to psychiatrists, gerontologists, clinical psychologists, social workers, students, trainees, and others who care for individuals over the age of sixty.

Download or read book Brain Tumor Imaging written by Elke Hattingen and published by Springer. This book was released on 2015-09-02 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the basics, the challenges and the limitations of state of the art brain tumor imaging and examines in detail its impact on diagnosis and treatment monitoring. It opens with an introduction to the clinically relevant physical principles of brain imaging. Since MR methodology plays a crucial role in brain imaging, the fundamental aspects of MR spectroscopy, MR perfusion and diffusion-weighted MR methods are described, focusing on the specific demands of brain tumor imaging. The potential and the limits of new imaging methodology are carefully addressed and compared to conventional MR imaging. In the main part of the book, the most important imaging criteria for the differential diagnosis of solid and necrotic brain tumors are delineated and illustrated in examples. A closing section is devoted to the use of MR methods for the monitoring of brain tumor therapy. The book is intended for radiologists, neurologists, neurosurgeons, oncologists and other scientists in the biomedical field with an interest in neuro-oncology.

Download or read book Tissue Engineered Vascular Grafts written by Beat H. Walpoth and published by Springer. This book was released on 2020-08-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular diseases are still the leading cause of death in developed countries. Revascularization procedures such as coronary artery and peripheral bypass grafts, as well as access surgery represent a 2$ billion market yearly for the US alone. Despite intense research over many decades, no clinically suitable, shelf-ready, synthetic, vascular, small-caliber graft exists. There is therefore still a quest for such a clinical vascular prosthesis for surgical revascularization procedures and access surgery. Many approaches have been tried and are currently under investigation with promising results. These range from acellular and cell-based, stable or bio-degradable, synthetic scaffolds to biological or decellularized grafts, not forgetting self-assembly technologies for in vitro or in vivo VTE. All these approaches can be further enhanced by functionalization, e.g. with growth factors and drug elution. This updatable book aims to cover all the relevant aspects of Vascular Tissue Engineering (VTE) and novel alternatives to develop vascular grafts for clinical applications. The chapters in this book cover different aspects of manufacturing scaffolds with various polymers, mechanical characteristics, degradation rates, decellularization techniques, cell sheet assembly, 3-D printing and autologous mandril-based VTE. All the necessary in vitro tests such as biocompatibility and thrombogenicity are reviewed. Pre-clinical assessment of in vivo experimental models include patency, compliance, intimal hyperplasia, inflammatory reaction, cellular ingrowth and remodeling. Finally, early clinical trials will be periodically updated regarding results, regulatory aspects and post-marketing quality assessment. Furthermore, the reader should get an insight into various approaches, technologies and methods to better understand the complexity of blood surface and cell interactions in VTE. Translational research has yielded early human applications clearly showing the enormous need of research in the field to provide better solutions for our patients and this continuously updated book will hopefully become a reference in the field for life sciences.

Download or read book Functional Neuroanatomy written by N. J. Strausfeld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "functional" in the title of this book not only reflects my personal bias about neuroanatomy in brain research, it is also the gist of many chapters which describe sophisticated ways to resolve structures and interpret them as dynamic entities. Examples are: the visualization of functionally identified brain areas or neurons by activity staining or intracellular dye-iontophoresis; the resolution of synaptic connections between physiologically identified nerve cells; and the biochemical identification of specific neurons (their peptides and transmitters) by histo- and immunocytochemistry. I personally view the nervous system as an organ whose parts, continuously exchanging messages, arrive at their decisions by the cooperative phenome non of consensus and debate. This view is, admittedly, based on my own ex perience of looking at myriads of nerve cells and their connections rather than studying animal behaviour or theorizing. Numerous structural studies have demonstrated that interneurons in the brain must receive hundreds of thousands of synapses. Many neurons receive inputs from several different sensory areas: each input conveys a message about the external world and possibly also about past events which are stored within the central nervous system. Whether an interneuron responds to a certain combination of inputs may be, literally, a matter of debate whose outcome is decided at the post synaptic membrane. A nerve cell responding to an overriding command is possibly a rare event.
