Buch. Zustand: Neu. Neuware -The observation in the 1950s that nitrogen mustard and other toxic chemicals could induce antitumor responses in patients with refractory lymphoma initiated a massive search for active chemotherapeutic agents. The initial observations stimulated a search for new chemotherapeutic agents which might have increased antitumor activity with less toxicity for normal tissues. To aid in the search for these new chemicals and to attempt to distinguish among the many toxic chemicals which might be candidates for clinical studies, the National Cancer Institute, the pharmaceutical industry, and the cancer research laboratories of most Western nations developed systems for 'screening' drugs for antitumor activity. Perhaps the most extensive screening program was established by the National Cancer Institute (1). This screening program has evolved over the last two decades, an evolution which has been repeatedly reviewed (2-5). Various screening programs in use have examined over 500,000 compounds as potential anticancer agents. From these, there are now approximately forty anticancer drugs in clinical use. The utiliy of these compounds and their toxicities have been reviewed on many occasions. It is now apparent that more active and less toxic anticancer drugs are needed. It is also clear that the current screening programs are identifying compounds with similar levels of activity and with continuing moderate to severe toxicity (6).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Zustand: Neu. Neuware - Interferon alpha-2 is a genetically engineered, highly purified pharmaceutical agent that has undergone extensive phase I and phase II clinical study in more than 1000 patients. The material has biological activity by intravenous, intramus cular and subcutaneous routes. Clinical toxicity principally involves the 'influen za like' syndrome previously seen with native interferons. Other important toxi cities include anorexia, hepatitis, confusion and myelosuppression. Tolerable doses in multiple schedules and routes of administration have been determined. Phase II clinical trials with multiple routes and schedules of administration have been performed. Significant clinical activity has been found in non Hodgkin's lymphomas (both low grade and high grade), refractory and relapsing multiple myeloma, hairy cell leukemia, Kaposi's sarcoma, with suggestions of activity in Hodgkin's disease, renal cell carcinoma, and melanoma. The studies performed to date have for the most part involved small numbers of heavily pre-treated patients. Large-scale clinical trials in some of these disea ses are now warranted in populations of patients with as little bulk disease and prior treatment as is feasible for each tumour type. This is particularly the case in . Hodgkin's disease and subcategories of the non-Hodgkin's lymphomas. Alterna tely, interferon alpha-2 might be used to maintain remissions induced by other modalities (i. e. , in NHL, multiple myeloma, ovarian cancer). In some advanced disease settings, combinations of interferon alpha-2 with chemotherapeutic agents should now be investigated.

Buch. Zustand: Neu. Neuware -With the recent increase in the scope of drug and alcohol problems has come an awareness of the need for solutions. In this context, federal support for research on drug problems increased tremendously during the last 10 to 15 years with the establishment of the National Institute on Drug Abuse (NIDA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Funding from these and other sources has led to a substantial increase in the quantity and quality ofpublished work related to substance abuse. As data accumulate, it is becoming more apparent that substance abuse problems are extremely complex and are influenced by a variety ofbiological psychological, and environmental variables. Un fortunately it has proved difficult to go beyond this conclusion to a de scription of how these multiple factors work tagether to influence the development of, and recovery from, drug and alcohol dependence. The purpose of this book is to try to meet that objective by including, in one volume, Iiterature reviews and theoretical analyses from a wide variety of drug researchers. We chose the authors in an attempt to assure that each of the various Ievels of analysis appropriate to the substance abuse problems would be included. In each case, the author was asked to consider how the variables in is or her particular domain might con tribute to the appearance of individual differences in both alcohol and drug problems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Englisch.

Buch. Zustand: Neu. Neuware - Prostaglandins, Leukotrienes, and Cancer is a multi-volume series that will focus on an emerging area of cancer research. In 1968, R.H. Williams first reported that elevated prostaglandin levels are present in human medullary car cinoma. Since that time, the concept that arachidonic acid metabolites may be in volved in cancer has expanded to include every aspect of the disease from cell transformation through metastasis. Prostaglandins and leukotrienes are generic terms used to describe a family of bioactive lipids produced from unsaturated fatty acids (principally from arachidonic acid) via the cyclooxygenase and lipoxygenase pathways, respec tively. Cyclooxygenase products consist of diverse products such as prosta glandin E2 (POE ), prostacyclin (POI ) and thromboxane A2 (TXA ), whereas 2 2 2 lipoxygenase products consist of hydroperoxy fatty acids and mono-, di- and tri-hydroxy acids including leukotrienes. The precursor fatty acids for the cyclooxygenase and lipoxygenase pathways are present in cellular phospholipids. This finding established an important control point in their biosynthesis-the release of substrate. This occurs in response to numerous stimuli that act at the cell surface. Dr. Bengl Samuelsson's extensive study of the metabolism of pros taglandins indicated that they are rapidly inactivated on a single pass through pulmonary circulation. Thus, they cannot act as circulating hormones and appear to be made on demand in or in the vicinity of target tissues leading to the concept that prostaglandins are local hormones or autocoids.

Buch. Zustand: Neu. Neuware - In summary, there are many animal models that are useful in selecting new antiarrhythmic drugs. The selection of which model is most idea depends upon precisely what question is being asked. The large number of experimental models used to evaluate antiarrhythmic compounds points out the inability of anyone model to define the probability of antiarrhythmic efficacy in man. It has therefore become standard practice to utilize a batter of animal models for the evaluation of new antiarrhythmic agents. Each model has its own advantages and disadvantages and it is necessary to understand each model fully in oder to evaluate experimental findings and apply them to clinical settings. We believe that the availability of the chronic myocardial infarction ventricular tachyarrhythmia model provides 1) an excellent opportunity to more precisely understand arrhythmia mechanisms, 2) to develop new techniques such as signal averaging for evaluating late low level potentials identifying hearts at high risk of sudden death 3) to identify new antifibrillatory drugs versus drugs that are effective primarily against PVC's and ventricular tachycardia 4) to identify new surgical techniques to eliminate VT/VF, and 5) to evaluate new pacing modalities including implantable cardioverters. Although all animal models are wrong, many are very useful in furthering our knowledge directed at decreasing the distressingly high mortality from heart disease. NORMAL HtART TACHYCMDIA HtART , .

Buch. Zustand: Neu. Neuware - The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on 'Fundamentals of Amorphous Materials and Devices' was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.

Buch. Zustand: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Examination of the early literature attests to the fact that the study of copolymerization was initiated when polymer science was in its infancy. It has continued to grow to a subject of major importance and has been a source of interest to both academic and industrialist alike. The wide spectrum of structures and properties available in the statistical copolymer has made this a fruitful field of exploration, but one particular and more restricted form which has held its own fascination for many is the limiting case of the strictly alternating copolymer. This is formed, in the ideal situation, when two monomers in a reaction mixture add consecutively to create a polymer chain with a regular {ABABAB} structure, irrespective of the monomer feed ratio. When this happens the resulting copolymer will always have the same composition, a feature which can be advantageous but also somewhat restrictive, as the ability to vary the properties is then limited. Within a series entitled Speciality Polymers it seems appropriate then to deal with this subject, particularly as no previous attempt has been made to draw together the various facets of alternating copolymerization into one volume. It also seems timely to present a more unified picture of the subject which will also illustrate the progress made.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 298 pp. Englisch.

The first of these symposia, entitled 'A Bridge Between Research and Application,' was held at the University in 1978 and was published by the Technical Information Center, Department of Energy. The second symposium, on 'Emerging Technologies and Strategies,' was held in 1980 and pub lished as a special issue of Environmental and Experimental Botany. One of the aims of these symposia was to examine the current state of-the-art in tissue culture technology and to relate this state of technology to practical, applied, and commercial interests. Thus, the third of this series on development and variation focused on embryogenesis in culture: how to recognize it, factors which affect embryogenesis, use of embryogenic systems, etc.; and variability from culture. A special session on woody species again emphasized somatic embryogenesis as a means of rapid propagation. This volume emphasizes tissue culture of forest trees. All of these areas, we feel, are breakthrough areas in which significant progress is expected in the next few years. 412 pp. Englisch.

The United Nations again in their desire to improve the sanitation conditions allover the world decided to proclaim the period between 1981-1990 as the 'International Drinking Water Supply and Sanitation Decade.' Although attempts have been made by inter national organizations to prevent pollution, it is difficult to say that these attempts gave satisfactory results in developing countries. The most common reasons of failure are: a) To find solutions to their environmental problems, develop ing countries usually seek the assistance of engineers and scientists from developed countries. Many times, how ever, either out of ignorance of the local condition or due to financial motivations, these experts come out with solutions which are far from being considered as the 'most appropriate.' As a result, the basic objective of protecting the environment is not achieved. b) Attempts made by developed countries to 'export' their wastes - especially the hazardous ones - to the developing world, is another danger - and sometimes reason of failure encountered in the field of Environmental Management. 692 pp. Englisch.
