This book was released on 1985-04-30 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 E, (POE,), prostacyclin (POI2) and thromboxane A2 (TXA2), whereas lipoxygenase products consist of hydroperoxy fatty acids and mono-, di- and tri-hydroxy acids including leukotrienes. The precursor fatty acids for the cyclooxygenase and lip oxygenase 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. Bengt 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.

Available in PDF, EPUB and Kindle. Book excerpt: Ten years after the discovery of prostacyclin, our knowledge of its biochemical mode of action, pharmacological properties, pathophysiological significance and therapeutic applications is ever expanding. Prostacyclin is both complex and unique as demonstrated by its unusual feature of being chemically and meta bolically unstable when compared to other prostanoids and known amine or peptide mediators. Although physiologically essential, the chemical instability of prostacyclin poses a serious drawback in laboratory and clinical studies. It is one of the genuine objectives of pharmaceutical research to supply synthetic compounds which overcome the inherent drawbacks - considering investigational and therapeutic use - of endogenous compounds. Whereas metabolic instability in certain cases could be of advantage, chemical instability definitely is not. With Iloprost, a molecule has been designed which - according to all data so far available - pertains high receptor affinity, metabolic instability (clinically this equates with a fine control of Iloprost's effects) while chemical stability has been achieved. By virtue of these characteristics Iloprost can be considered as one step towards specific interaction within the arachidonic acid cascade, namely the prostacyclin receptor. The aim of the symposium was to provide a critical experimental appraisal concerning the biochemical mode of action and pharmacological properties of prostacyclin and Iloprost.

Book excerpt: Nutritional oncology is an increasingly active interdisciplinary field where cancer is investigated as both a systemic and local disease originating with the changes in the genome and progressing through a multi-step process which may be influenced at many points in its natural history by nutritional factors that could impact the prevention of cancer, the quality of life of cancer patients, and the risk of cancer recurrence in the rapidly increasing population of cancer survivors.Since the first edition of this book was published in 1999, the idea that there is a single gene pathway or single drug will provide a cure for cancer has given way to the general view that dietary/environmental factors impact the progression of genetic and cellular changes in common forms of cancer. This broad concept can now be investigated within a basic and clinical research context for specific types of cancer. This book attempts to cover the current available knowledge in this new field of nutritional oncology written by invited experts. This book attempts to provide not only the theoretical and research basis for nutritional oncology, but will offer the medical oncologist and other members of multidisciplinary groups treating cancer patients practical information on nutrition assessment and nutritional regimens, including micronutrient and phytochemical supplementation. The editors hope that this volume will stimulate increased research, education and patient application of the principles of nutritional oncology.NEW TO THIS EDITION:* Covers hot new topics of nutrigenomics and nutrigenetics in cancer cell growth * Includes new chapters on metabolic networks in cancer cell growth, nutrigenetics and nutrigenomics* Presents substantially revised chapters on breast cancer and nutrition, prostate cancer and nutrition, and colon cancer and nutrition* Includes new illustrations throughout the text, especially in the breast cancer chapter* Includes integrated insights into the unanswered questions and clearly defined objectives of research in nutritional oncology * Offers practical guidelines for clinicians advising malnourished cancer patients and cancer survivors on diet, nutrition, and lifestyle * Provides information on the role of bioactive substances, dietary supplements, phytochemicals and botanicals in cancer prevention and treatment

Available in PDF, EPUB and Kindle. Book excerpt: Dysmenorrhea is estimated to effect upwards of 70% of women during their lifetime and “heavy menstrual periods” is one of the most frequently given reasons for hysterectomy in the United States. Despite the dramatic growth of dysmenorrhea treatment with non-steroidal anti-inflammatory agents (NSADs) in the 1980s, young women continue to go undiagnosed and under treated. The diagnosis and management of heavy menstrual bleeding has even poorer general understanding because of its more complicated etiologies. With a working knowledge of the underlying pathophysiology, all clinicians should be able to establish both the diagnosis and a credible treatment plan that will result in a significant chance of clinical improvement for most patients. This book addresses the pathophysiologic underpinnings of both dysmenorrhea and menorrhagia and provides clinicians with practical approaches to establishing the diagnosis, proven tactics for successful therapeutic interventions and dealing with the challenging atypical case, and effective patient counseling. It teaches principles, including the role prostaglandins play in both conditions, as well as procedures, like surgical options and TENS, providing a balance of the practical and the esoteric. The inclusion of patient education and counseling materials additionally increases its usefulness for the busy clinician. This is an ideal guide for ob/gyn clinicians, residents, and trainees caring for patients with these common, but often misunderstood diseases.

Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: In OCtober 1986, recognized authorities from a variety of disciplines met in Lisbon, Portugal, to review recent knowledge on eicosanoids - i. e., prostaglandins, throm boxane A , and leukotrienes - and their role in gastrointestinal diseases. 2 Briefly, in the stomach endogenous as well as exogenous prostaglandins may mediate cytoprotective actions in that they stimulate gastric mucus production, bicar bonate secretion and cellular regeneration while providing adequate mucosal blood flow. In contrast, thromboxane A2 by vasoconstriction may act as an ulcerogenic substance. Diarrheal states may be associated with prostaglandins of types E and F as they are capable to enhance intestinal water and electrolyte secretions. In chronic in flammatory bowel disease, mucosal synthesis of leukotrienes was found to be increased more markedly than that of prostaglandins suggesting that leukotrienes may have a major part in the pathogenesis of that disease. In this volume, which is an elaborated collection of the papers given on occasion of the above-mentioned symposium, the facts and problems associated with prostanoid substances are dealt with in four sections on 1. biochemistry, biology and pharmacology of eicosanoids, 2. physiologic and pathophysiologic aspects, 3. established therapeutic implications, and 4. treatment perspectives. We believe that the publication of these contributions by leading workers in the given fields provides a comprehensive and up-to-date appraisal of the role of eicosanoids in gastrointestinal diseases, and it is hoped that this volume will be of value to both basic scientists and practicing clinicians.
