Available in PDF, EPUB and Kindle. Book excerpt: En cardiologie, l'étude de la contraction ventriculaire gauche, tant à l'échelle globale que segmentaire, apporte des informations diagnostiques et pronostiques majeures, orientant les décisions thérapeutiques et le suivi du patient. Plusieurs techniques d'exploration non invasives permettent une telle évaluation fonctionnelle du ventricule gauche, avec notamment en médecine nucléaire, la tomoventriculographie isotopique (TVI) et la scintigraphie de perfusion myocardique (SPM). Le but de notre étude a été de comparer les données apportées par ces deux examens en terme d'analyse de la cinétique ventriculaire gauche. MATERIEL ET METHODES Nous avons inclus de manière rétrospective les patients suivis ou suspects de cardiopathie ischémique, qui nous avaient été réferrés de janvier 2004 à décembre 2012, chez qui une SPM et une TVI avaient été réalisées de façon rapprochée. Nous avons ainsi comparé ces deux examens, à la fois pour leurs estimations de la fraction d'éjection (FEVG) et des volumes ventriculaires tél édiastolique (VTD) et télésystolique (VTS) qui reflètent la contraction du ventricule gauche à l'échelle globale, mais également les paramètres fonctionnels segmentaires qui étaient obtenus, et en particulier l'épaississement (SPM-T) et le déplacement (SPM-M) de la paroi myocardique en systole estimés en SPM (23 SPM utilisant la 99mTc-tetrofosmin, et 50 SPM au chlorure de 201Thallium), et les valeurs de fraction d'éjection ventriculaire gauche segmentaire (TVI-FEs) obtenues en TV!. RESULTATS: La corrélation entre SPM et TVI était excellente en ce qui concerne la FEVG ( r = 0,89 et 0,88 pour les groupes SPM(99mTc-tetrofosmin) versus TVI, et SPM(201Thallium) versus TVI respectivement) et les volumes ventriculaires gauches (VTD: r = 0,81 et 0,90 ; p

This book was released on 2012-12-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2 The free internal Ca+ concentration in human red cells is set according to the leak 2 and-pump principle: There is a finite passive Ca+ influx at the physiological 2 2 Ca+ -gradient across the membrane which is compensated by Ca+ pumping in the outward direction with a rate given by the degree of saturation of the A TP-fuelled Ca 2 pump at the steady-state internal Ca+ concentration. Simons (1982) recently devised a method allowing the measurement of the steady 2 2 state internal Ca+ concentration. Cells are suspended in media of different Ca+ con 2 2 tent whose Ca+ concentration is monitored by a Ca+ -selective electrode. When the cells are lysed (by digitonin) there is an upward or downward deflection of the elec 2 trode signal. At the point of zero deflection, the cellular Ca+ concentration equals that 2 of the medium. The result is, that in fresh human red blood cells the Ca+ concentra tion is ;;;; O.4,uM (this is an upper estimate; the true value may be considerably lower).
Download or read book Coronary Microvascular Dysfunction written by Filippo Crea and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.

Download or read book Gene Therapy of the Central Nervous System From Bench to Bedside written by Michael G. Kaplitt and published by Elsevier. This book was released on 2005-11-11 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few areas of biomedical research provide greater opportunities for radically new therapies for devastating diseases that have evaded treatment so far than gene therapy. This is particularly true for the brain and nervous system, where gene transfer has become a key technology for basic research and has recently been translated to human therapy in several landmark clinical trials. Gene Therapy of the Central Nervous System: From Bench to Bedside represents the first definitive volume on this subject. Edited by two pioneers of neurological gene therapy, this volume contains contributions by leaders who helped create this field and are expanding the promise of gene therapy for the future of basic and clinical neuroscience. Drawing upon this extensive collective experience, this book provides clear and informative reviews on a variety of subjects of interest to anyone exploring or using gene therapy for neurobiological applications in research and clinical praxis.* Presents gene transfer technologies with particular emphases upon novel vehicles, immunological issues and the role of gene therapy in stem cells* Discusses preclinical areas that are likely to translate into clinical studies in the near future, including epilepsy, pain and amyotrophic lateral sclerosis* Includes "insider" information on technological and regulatory issues which can often limit effective translation of even the most promising idea into clinical use

Available in PDF, EPUB and Kindle. Book excerpt: Color Atlas of Equine Pathology offers a practical guide to identifying equine diseases, presenting a single resource with more than 1000 images showing predominantly gross pathology. Organized by body systems, the book allows for picture matching during or after an equine necropsy. In this user-friendly atlas, each chapter takes a common format, presenting the disease process as well as congenital, degenerative, inflammatory, and neoplastic sequences, with text boxes offering quick reference to key information. The book begins with an introductory chapter summarizing the principles of the equine field necropsy, and subsequent organ-based chapters depict gross features of disease, focusing on macroscopic digital images supplemented by histology and immunohistochemistry when necessary. Some clinical information for correlation with pathology is included. Color Atlas of Equine Pathology is an essential resource for diagnostic veterinary pathologists and pathology residents, as well as for equine practitioners performing necropsies in the field.

This book was released on 2001-12-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurement of Cardiac Deformations from MRI: Physical and Mathematical Models describes the latest imaging and imag analysis techniques that have been developed at leading centers for the visualization, analysis, and understanding of normal and abnormal cardiac motion with magnetic resonance imaging (MRI). The use of MRI in measuring cardiac motion is particularly important because MRI is non-invasive, and it is the only modality capable of imaging detailed intramural motion within the myocardium. Biomedical engineers, medical physicists, computer scientists, and physicians interested in learning about the latest advances in cardiovascular MRI should find this book to be a valuable educational resource. In particular, it is more tutorial in nature than most of the technical papers where the research was originally published. Practitioners and researchers working in the field of cardiovascular MRI will find the book to be filled with practical technical details and references to other work, enabling the implementation of existing methods and serving as a basis for further research in the area.
