Available in PDF, EPUB and Kindle. Book excerpt: This book is formulated from a number of presentations made at a one-day workshop on the subject of Photon Migration in Tissues. The meeting was held in Philadelphia at the University of Pennsylvania, April, 1988. The workshop was an impromptu effort to bring together scientists to discuss photon migration in animal tissues and appropriate models. The rapid emergence of the ideas of Townes and Schalow in their invention of the then called maser, now laser opened up completely unexpected possibilities for biomedical research. Timing of rapid biochemical reaction, identification of unstable intermediates, spectroscopy of short lived fluorescent states were all goals to be expected and achieved. At the same time continuous light spectroscopy of tissue slices and of the myocardium, and eventually of the brain have the to the the neonate emerged over years. Shifting red end of spectrum, Butler and Norris clearly showed how transparent plant materials and the human hand could be illuminated in this region and Jobsis applied their idea to the neonate brain using a multiwavelength technique.

Available in PDF, EPUB and Kindle. Book excerpt: Biomedical optical imaging is a rapidly emerging research area with widespread fundamental research and clinical applications. This book gives an overview of biomedical optical imaging with contributions from leading international research groups who have pioneered many of these techniques and applications. A unique research field spanning the microscopic to the macroscopic, biomedical optical imaging allows both structural and functional imaging. Techniques such as confocal and multiphoton microscopy provide cellular level resolution imaging in biological systems. The integration of this technology with exogenous chromophores can selectively enhance contrast for molecular targets as well as supply functional information on processes such as nerve transduction. Novel techniques integrate microscopy with state-of-the-art optics technology, and these include spectral imaging, two photon fluorescence correlation, nonlinear nanoscopy; optical coherence tomography techniques allow functional, dynamic, nanoscale, and cross-sectional visualization. Moving to the macroscopic scale, spectroscopic assessment and imaging methods such as fluorescence and light scattering can provide diagnostics of tissue pathology including neoplastic changes. Techniques using light diffusion and photon migration are a means to explore processes which occur deep inside biological tissues and organs. The integration of these techniques with exogenous probes enables molecular specific sensitivity.

Available in PDF, EPUB and Kindle. Book excerpt: The Ottawa '88 meeting of the International Society for Oxygen Transport to Tissue attracted a record number of participants and presentations. We were able to avoid simultaneous sessions and still keep the scientific program to four days by using poster sessions followed by plenary debate on each poster. To paraphrase the British physicist David Bohm, we tried to avoid an ordinary discussion, in which people usually stick to a relatively fixed position and try to convince others to change. This situation does not give rise to anything creative. So, we attempted instead to establish a true dialogue in which a person may prefer and support a certain point of view, but does not hold it nonnegotiab1y. He or she is ready to listen to others with sufficient sympathy, and is also ready to change his or her own view if there is a good reason to do so. Our Society is in its "teen" years, and there are even some arguments about its exact age. Many newer members have raised questions concerning the history of the Society. For this reason, I have asked one of the "founding fathers", D. Bruley, to prepare a brief account of the birth and early history of the Society which appears on the following page.

Available in PDF, EPUB and Kindle. Book excerpt: The International Society on Oxygen Transport to Tissue (ISOTT) was founded in 1973 "to facilitate the exchange of scientific information among those interested in any aspect of the transport and/or utilization of oxygen in tissues". Its members span virtually all disciplines, extending from various branches of clinical medicine such as anesthesiology, ophthalmology and surgery through the basic medical sciences of physiology and'biochemistry to most branches of the physical sciences and engineering. The seventeenth annual meeting of ISOTT was held in 1989 for four days, from July 21 to 24, at the Max Planck Institute for Experimental Medicine and the adjoining University Hospital (Klinikum), in Goettingen, Federal Republic of Germany. It attracted 147 active registrants and approximately 40 accompanying persons. The very successful format originated by Dr. Ian Longmuir in 1985, consisting of posters accompanied by an abbreviated oral summary, was continued with slight modification. Virtually all of the presentations utilized this format, with each poster session preceded by a formal discussion during which the presenter briefly reviewed the poster aided by a few slides. All posters remained in place for the entire four days of the meeting.

Download or read book Tissue Oxygen Utilization written by Guillermo Gutierrez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbances in peripheral O extraction can be produced in dogs treated with 2 endotoxin and thereby provide an opportunity to test theories for the origin of pathological O supply dependency or to try different treatment modalities. The 2 most serious deficiency in the current animal models is the inability to mimic the increased O demand that is observed in patients at 02 delivery rates in excess of 2 normal. A particular feature of this increased O demand is that it apparently does 2 not stimulate increased 02 extraction, although the limitation in O extraction has 2 not been explored in patients by lowering 02 supply, for obvious reasons. At least two possibilities to account for increased 02 demand could be investigated in animal models, however. The amount of 02 that is utilized in extramitochondrial pathways, which is normally on the order of 10%, may be greatly increased in ARDS and sepsis by O radical formation. There is presently no information 2 concerning how much 02 might be used in this way. Another strong possibility is that mitochondrial injury, perhaps as a result of 02 radical formation, uncouples oxidative phosphorylation. Some evidence presently in the literature supports this idea [19]. Indeed, the association of increased blood lactate levels with higher than expected 02 demands makes uncoupling a very attractive hypothesis that warrants further investigation in animal models using such agents as 2,4-dinitrophenol.

Download or read book Interventional Bronchoscopy written by Christoph T. Bolliger and published by Karger Medical and Scientific Publishers. This book was released on 2000 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects of diagnostic and therapeutic bronchoscopy, which go beyond the techniques of inspection, simple lavage and biopsies of the tracheobronchial tree. In a first section, historical aspects as well as the modern use of both rigid and flexible instruments, the set-up of a bronchoscopy unit, anaesthetic techniques, and functional evaluation for patients undergoing interventional bronchoscopy are discussed. A diagnostic section on transbronchial needle aspiration and bronchoscopic ultrasound is followed by extensive coverage of all existing therapeutic techniques: foreign body removal, laser resection, electrocautery, argon plasma coagulation, cryotherapy, brachytherapy, photodynamic therapy, stenting, and a chapter on multi-modality treatment of advanced pulmonary malignancies. A fourth section deals with percutaneous image-guided procedures, percutaneous dilatational tracheostomy, and transtracheal oxygen therapy. The last section provides an in-depth look at emerging bronchoscopic technology, such as autofluorescence, virtual bronchoscopy, and gene therapy. Written by the world's leading authorities in the field and beautifully illustrated, this book presents the state of the art of interventional bronchoscopy. It is recommended reading for pulmonologists, thoracic or ENT surgeons, oncologists and physicians who take an interest in bronchoscopy.
