Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The remaining years of our ending millennium are characterized by a tempestuous devel opment of Surface Science, whose ultimate consequences are presently hard to foresee. While some of these consequenees are apparent to everybody (e. g. modern information eleetronies would hardly be possible without the progress in device fabrication whieh, in turn, has required profound knowledge of surface teehnology ) there are several other dis ciplines where the impact of surface physical chemistry may not be so obvious, but, nevertheless, has contributed much to the technological progress made in the past, and is expected to cause even more such benefit in the future. We only list here the c1assical syn thetic inorganic chemistry or the technical chemistry which have both greatly benefited from a more fundamental understanding of heterogeneously catalyzed (surface) pro cesses leading to, among others, improved industrial fabrication processes. (We selec tively mention the promising attempts to model the Fischer-Tropseh reaction or the ammonia synthesis reaction, remembering also the optimization of the hydrocarbon reforming proeess by developing appropriate bi metallic catalyst materials). Furthermore, materials science with its considerations of eorrosion, embrittlement, and fracture, as weIl as energy technology with its considerations of photovoltaics, hydrogen storage, or fuel cell development, must also be mentioned here. Many other important aspeets remain unmentioned, because of space limitations. 274 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With this book, it was not our intention to provide a complete 'textbook' on axial pumps and their use as temporary cardiac assist systems. It is more a sharing of experiences with a novel left-ventricular assist system, the Hemopump, as it was developed by R. K. Wampler. This device, marketed by Johnson & Johnson Interventional Systems, has not yet been widely used and accepted in clinical practice. It was offered to us some time ago to study its applicability in the experimental setting. At the moment, it is under investigation in many centers and it is commercially available. However, as with any other cardiac assist system, the axial pump has its own advantages and limitations. Needless to say, critical analysis of such a novel device is mandatory and, therefore, we are grateful to our colleagues who were willing to contribute to this book. They present, discuss, and analyze their experimental and clinical experience with the Hemopump and focus on side-effects, deficiency and efficiency of this device which, by virtue of its simplicity is revolutionary.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although surgical and catheter-based revascularization techniques have substan tially improved today's therapeutic potential in ischemic heart disease, in the majority of patients treatment will be conservative for a number of reasons, the cost-effectiveness of non-pharmacological approaches being of major importance. During the last two decades, drug development for ischemic heart disease has been impressive and many new compounds have been added to our therapeutic armamentarium. Nevertheless, where mode of action is concerned, it is interesting to note that, despite all these efforts, we are still confined to three categories of drugs. Antithrombotics and platelet-active agents aside, these concern nitrates, betablocking drugs and calcium antagonists, agents which reduce ischemia by diminishing cardiac work or wall stress, thereby affecting myocardial oxygen demand and/or by improving coronary blood flow. Alone or in combination, these agents have proved to be efficacious in the treatment of angina pectoris or other symptoms of ischemic heart disease in a number of patients, but certainly not in all. Moreover, as side-effects are often a problem with current antianginal compounds, the physician may find himself restricted in his therapeutic capabilities and in need of new and, preferably, alternative forms of pharmacological treatment. 76 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Entzugserscheinungen nach jahrelangem Drogen-und Alkoholabusus entwickeln sich nach sehr ahnlichen pathophysiologischen Mustern und sind in ihrer Entste hung oft schwierig zu deuten. Sie auBern sich vorwiegend in vegetativen Reaktionen, die meist den initialen Wirkungen entgegengesetzt sind. Ihre Intensitat ist je nach Substanz, Dosis, Darreichungsart und Dauer der Anwendung unterschiedlich. Toleranzbildung und die Entwicklung einer Abhangigkeit nach chronischem AlkoholmiBbrauch erschweren die Betreuung von Patienten vor allem in der postoperativen Phase. Angesichts der steigenden Anzahl alkoholabhangiger Patienten in unserer Gesellschaft kommt daher der Prophylaxe und Therapie des Alkoholentzugssyndroms bei gegebener Operationsindikation wachsende Bedeu tung zu. Das standig zunehmende Interesse an praventiven MaBnahmen fiihrte im Februar 1990 Experten in Hannover zu einem Symposium zusammen, das der Diskussion gegenwartiger und neuer Aspekte der Delirtherapie und -prophylaxe gewidmet war. Die in dem vorliegenden Kompendium zusammengefaBten Beitrage geben einen Einblick in die Klinik und Pathophysiologie des Alkoholentzugsdelirs. Dartiber hinaus werden wichtige Fragen der Pharmakologie und Pharmakokinetik behan delt und praktisch-therapeutische Konsequenzen aufgezeigt. Eine orale Alkoholmedikation ist wohl bei kleineren Eingriffen in speziellen Fallen erfolgreich, dartiber hinaus gilt es jedoch, dem Therapeuten ein angemes senes medikamentoses Konzept zur Delirprophylaxe und -therapie an die Hand zu geben. 1m Mittelpunkt des Interesses steht derzeit die Beeinflussung der Entzugssym ptome bei Alkoholabhangigen durch Gabe zentral wirkender urStimulanzien. 80 pp. Deutsch.…
