Download or read book Blood Viscosity and Shock written by H. Goslinga and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hemodynamic significance of the flow properties of blood was put into perspective only during the past decade. Advances in modern technologies today allow the quantitative analy sis of the fluidity of blood and its components under conditions approximating the flow in vivo, particularly those in the microcirculation. The hematocrit is the most important of the determinants of blood fluidity (reciprocal value of blood viscosity); acute increases in the hematocrit exert deleterious effects on circulation and oxygen transport owing to impaired fluidity of blood. High viscosity of plasma due to hyper- or dysproteinemias initiates the microcirculatory dysfunctions in hyperviscosity syndromes. Furthermore, the fluidity or deformability of red cells might be critically diminished and therefore cause redistribution of blood elements and adversely affect the resistance to flow within the microvessels. In low flow states blood fluidity most likely becomes the key determinant for microvessel perfu sion, overriding the neural and local metabolic control mechanisms operative at physiological conditions to adjust blood supply to tissue demand. Microcirculatory disturbances are there fore encountered whenever driving pressures are reduced, as in shock or hypotension, and distal to stenoses of macrovessels, but also in hemoconcentration due to plasma volume con traction, polycythemia, leukemia, and dysproteinemia. Based on experimental studies exploring the possibilities and limitations, with regard to improving the fluidity of blood by reducing the hematocrit, the concept of intentional hemo dilution has been introduced to clinical medicine.

Available in PDF, EPUB and Kindle. Book excerpt: At the VIIth International Congress on Rheology, which was held in Goteborg in 1976, Proceedings were for the first time printed in advance and distributed to all participants at the time of the Congress. Although of course we Italians would be foolish to even try to emulate our Swedish friends as far as efficiency of organization is concerned, we decided at the very beginning that, as far as the Proceedings were concerned, the VIIIth International Congress on Rheology in Naples would follow the standards of time liness set by the Swedish Society of Rheology. This book is the result we have obtained. We wish to acknowledge the cooperation of Plenum Press in producing it within the very tight time schedule available. Every four years, the International Congress on Rheology represents the focal point where all rheologists meet, and the state of the art is brought up to date for everybody interested; the Proceedings represent the written record of these milestones of scientific progress in rheology. We have tried to make use of the traditions of having invited lectures, and of leaving to the organizing committee the freedom to choose the lecturers as they see fit, in order to collect a group of invited lectures which gives as broad as possible a landscape of the state of the art in every relevant area of rheology. The seventeen invited lectures are collected in the first volume of the proceedings.

This book was released on 2013-03-09 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal purpose of a NATO (North Atlantic Treaty Organization) Advanced Research Workshop, a part of the NATO Advanced Study Institutes Programme, is to: (a) exchange thoughts at the frontiers of knowledge or at the frontiers of two (or more) fields or sectors; (b) review and assess the state of the art; (c) formulate recommendations for future research directions; (d) formulate plans for large international scientific experiments. The aim of the ARW on "Microvascular, rheological, metabolic and heat-transfer aspects of the heart: relation to ischaemia and thrombosis", convened in Chateau de Bonas, July 4-11, 1982, was to describe functions and performance of the heart in an interdisciplin ary effort, involving cardiologists, pathologists, biochemists, haemorheologists, physiologists, pharmacologists and bioengineers; to explore interactions between such subfields as blood rheology, micro circulation and ischaemia of the myocardium, heat transfer, heat work and performance as a pump, effect of -metabolites and ion transfer, mechanism of sudden death, protein synthesis and protein molecular transformations. One of the purposes of the Convenor was to relate clinical haemorheology to the heart energetics and heart metabolism. This was only partly established, as difficulties of communications between different fields, difficulties of semantics and of specialized out looks could not be overcome within a -few days. Nevertheless, a gate was opened for communications interchange in the future. There was even a problem within each specialty, and as is rather common, quite diverse views have been expressed. This, of course, is quite normal in the progress of science.
Download or read book Australian Dictionary of Biography 1981 1990 written by Diane Langmore and published by The Miegunyah Press. This book was released on 1966 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 17 of the Australian Dictionary of Biography contains 658 biographies of individuals who died between 1981 and 1990. The first of two volumes for the decade, it presents a colourful mosaic of twentieth-century Australian life. It contains biographies of well-known identities such as Sir Henry Bolte, Sir Robert Askin, Sir Reginald Ansett, Sir Macfarlane Burnet, Sir Raphael and Lady Cilento, Sir Arthur Coles, Robert Holmes-O-Court, Sir Warwick Fairfax, Sir Edmund Herring, Albert Facey, Donald Friend, Sir Roy Grounds, Sir Bernard Heinze and Sir Robert Helpmann. Eminent Australian women in the volume include Dame Elizabeth Couchman, Dame Kate Campbell, Dame Doris Fitton, Dame Zara Holt and Lady (Maie) Casey. Although many of the women achieved prominence in those professions conventionally regarded as the preserve of women, othersandmdash;such as Ruby Boye-Jones, coast-watcher; Ellen Cashman, union organiser; Elsie Chauvel, film-maker; Dorothy Crawford, radio producer; Ruth Dobson, diplomat; Mary Hodgkin, anthropologist; Margaret Kelly, restaurateur; and Patricia Jarrett, journalistandmdash;demonstrate that some women at least were breaking free of the constraints of traditional expectations. The lives of fifteen Indigenous Australians are included, as are those of a number of immigrants who fled from persecution in Europe to establish a new life in Australia.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book remains the same as that stated in the first edition: to present a comprehensive perspective of biomechanics from the stand point of bioengineering, physiology, and medical science, and to develop mechanics through a sequence of problems and examples. My three-volume set of Bio mechanics has been completed. They are entitled: Biomechanics: Mechanical Properties of Living Tissues; Biodynamics: Circulation; and Biomechanics: Motion, Flow, Stress, and Growth; and this is the first volume. The mechanics prerequisite for all three volumes remains at the level of my book A First Course in Continuum Mechanics (3rd edition, Prentice-Hall, Inc. , 1993). In the decade of the 1980s the field of Biomechanics expanded tremen dously. New advances have been made in all fronts. Those that affect the basic understanding of the mechanical properties of living tissues are described in detail in this revision. The references are brought up to date.
Download or read book Blood Filtration and Blood Cell Deformability written by John A. Dormandy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. J. Meiselman From the theoretical studies of Dr. Skalak, it is clear that white cells can significantly influence the pressure-time profile of a red cell/white cell suspen sion, and that the presence of even a small amount of relatively rigid white cells can have a profound effect on the filtration pressure during the latter portion of a filtration experiment. Conversely, white cell effects, regardless of their relative rigidity, are shown to have only minimal effects during the very early (i. e. , 0-2 seconds) phases of the filtration process. Dr. Chien's experimental data support these theoretical studies, in that white cells of different mechan ical properties exhibit different pressure-time curves; pressure-time data for mixtures of leucocytes show shapes which can be predicted from the behavior of relatively homogeneous cell populations. The insensitivity of the very early portions of the filtration process to white cells is again reflected in the calculations made by Dr. Hanss. Using the nominal dilutions, white cell concentrations and the total volume of filtered cell suspension, he indicates that usually less than 1 pore out of 100 is liable to blockage by white cells. He thus concludes that, at the 1% accuracy level, initial filtration data should not be affected by mechanical pore blockage by white cells. Experimental studies by Dr. Lowe and Dr. Stuart question the WBC insensitivity of the early portion of the filtration process. Using a constant flow system, Dr.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The Department of Engineering Science and Hechanics at Virginia Polytechnic Institute and State University spon sored the First Mid-Atlantic Conference on Bio-Fluid Mechanics, which was held in Blacksburg, Virginia during the period 9-11 August 1978. Some 40 life-scientists, engineers, physicians and others who share a common interest in the advancement of basic and applied knowledge in bio fluid mechanics gathered at the Donaldson Brown Center for Continuing Education to hear 25 papers presented in seven technical sessions. At the conclusion of the conference, those present decided unanimously that its success warranted having at least one more -- and that it was conceptually a sound idea to plan it on a biennial basis for late spring. Hence, the second Mid-Atlantic Conference on Bio Fluid Mechanics took place at Virginia Tech on May 4-6, 1980. This volume documents the Proceedings of the second conference. It contains full texts of 23 contributed papers, 2 guest lectures and 1 invited seminar. The papers are gr9uped according to subject matter, beginning with 3 in the area of respiration, followed by 1 in kidney dialysis, 1 in reproduction, 1 in joint lubrication, 1 in prosthetic fluidics, 2 in zoology, and ending with 14 in the general field of cardiovascular dynamics. Of the latter, 5 deal with the subject of heart valves, 2 concern themselves with the microcirculation, 6 address vascular system hemodynamics and 1 covers some aspects of blood rheology.

Download or read book Therapeutic Hemorheology written by Albrecht M. Ehrly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemorheologic therapy has gained considerably in importance in recent years. This detailed and comprehensive book enumerates, discusses, and critically evaluates those treatment methods in which therapeutic success rests essentially on achieving an improvement in hemodynamics. After a general account of clinical hemorheology, fundamental aspects of hemorheologic methods and the eval- uation and assessment of hemorheologic parameters are discussed and the pathophysiology is described in detail. The treatment methods and substances that bring about improvement of the hemodynamics are described in chronologic order of first publication, and in each case all known later publications are also discussed in the order in which they appeared. This topical account of hemorheologic therapy - the results reported to date and the spectrum of applications - will be a valuable addition to the library both of the specialist and of all interested doctors in hospital and general practice.
