Angiogenesis: From the Molecular to Integrative Pharmacology (Advances in Experimental Medicine and Biology #476)

by Michael E. Maragoudakis

Proceedings of the 5th Biannual International Meeting on Angiogenesis: From the Molecular to Integrative Pharmacology, held July 1-7, 1999, in Crete, Greece. Angiogenesis, as a vastly complex biological process, has challenged researchers from all basic scientific disciplines, including pharmacology, biochemistry, physiology, embryology and anatomy. The significance of this phenomenon for the study of disease states has also interested clinicians from a number of specialist fields. This multidisciplinary work reflects the growth of awareness of concepts such as angiogenesis based therapy, the enormous therapeutic and commercial potential of which has attracted major research and investment in recent years. This volume, which aims to bridge the gap between basic and clinical methodology and understanding, presents the most up-to-date developments in this field.

Angiogenesis: Molecular Biology, Clinical Aspects (Nato Science Series A: #263)

by Michael E. Maragoudakis Pietro M. Gullino Peter I. Lelkes

Angiogenesis is a multistep process, which involves activation, proliferation and directed migration of endothelial cells to form new capillaries from existing vessels. Under physiological conditions, in the adult organisms angiogenesis is extremely slow, yet it can be activated for a limited time only in situations such as ovulation or wound healing. In a number of disease states, however, there is a derangement of angiogenesis, which can contribute to the pathology of these conditions. Hence, understanding the molecular biology of endothelial cell activation and differentiation and the mechanisms involved in the regulation of angiogenesis, could explain the derangement in disease states and also provide the basis for developing promoters or suppressors of angiogenesis for clinical applications. This book contains the proceedings of the NATO Advanced Study Institute on "Angiogenesis: Molecular Biology, Oinical Aspects" held in Rhodes, Greece, from June 16-27, 1993. This meeting was a comprehensive review of the various aspects of angiogenesis such as embryonic development, endothelial cell heterogeneity and tissue specificity, molecular biology of endothelial cell, mechanisms for the regulation of angiogenesis, disease states in which angiogenesis is involved and potential application of promoters or suppressors of angiogenesis. The presentations and discussions of the meeting provided an opportunity for investigators from many different areas of basic science and medicine to exchange information, evaluate the present status and provide future research directions in the field of angiogenesis.

Angiogenesis and Anti-Angiogenesis in Hematological Malignancies

by Domenico Ribatti

It has been generally accepted that angiogenesis is involved in the pathogenesis of hematological malignancies, like acute and chronic leukemia, lymphoma, myelodysplastic syndromes, myeloproliferative neoplasms and multiple myeloma. The extent of angiogenesis in the bone marrow has been correlated with disease burden, prognosis and treatment outcome. Reciprocal positive and negative interactions between tumor cells and bone marrow stromal cells, namely hematopoietic stem cells, fibroblasts, osteoblasts/osteoclasts, endothelial cells, endothelial progenitor cells, T cells, macrophages and mast cells, mediated by an array of cytokines, receptors and adhesion molecules, modulate the angiogenic response in hematological tumors. More recently, it has been emphasized the pro-angiogenic role of the so called “vascular niche”, indicating a site rich in blood vessels where endothelial cells and mural cells such as pericytes and smooth muscle cells create a microenvironment that affects the behavior of several stem and progenitor cells, in hematological malignancies.

Angiogenesis and Vascularisation: Cellular and Molecular Mechanisms in Health and Diseases

by Józef Dulak, Alicja Józkowicz and Agnieszka Łoboda

The book presents the overview of the current knowledge in some fields of vascular biology, addressing cellular and molecular aspects of blood-vessel formation and their role in health and disease. The major factors involved in the formation of blood vessels are presented by scientists actively involved in this area of research. Special emphasis is put on the presentation of various molecular mechanisms not addressed in similar works to date. The book is divided into three parts. The first part describes the cells and mediators in angiogenesis. The significance of various populations of potential endothelial progenitors is particularly highlighted. The chapters of the second part focus on molecular mechanisms, with special emphasis on the role of hypoxia, gasotransmitters and reactive oxygen species as well as microRNAs in regulation of angiogenic processes. In the third part, the pathological aspects of disturbed – aggravated or impaired – vascularization are discussed and new modalities for potential therapies are presented. The book is intended for scientists and PhD students in the fields of vascular biology and cancer research. It may be of interest for medical professionals in the fields of cardiovascular disease, diabetes, oncology and rheumatoid arthritis.

Angiogenesis in Adipose Tissue

by Yihai Cao

Angiogenesis has recently played a critical role in regulation of adipose tissue expansion and regression. Like most other tissues in the body, adipose expansion and regression is accompanied by alteration of blood vessel density and structures. The vascular alteration plays an active role in regulation of adipose tissue size and functions. Targeting blood vessels in the adipose tissue have demonstrated to be a novel approach for possibly treatment of cancer, obesity and other metabolic diseases. This book provides the most updated information on this type research and discusses future opportunities for therapy..

Angiogenesis in Health and Disease (Nato Science Series A: #227)

by Michael E. Maragoudakis Pietro M. Gullino Peter I. Lelkes

Angiogenesis describes the formation of new blood vessels, which arise as outgrowths from existing vessels. In many physiological processes such as ovulation and wound healing angiogenesis is involved for a relatively short time. Otherwise under normal physiological conditions in the adult organism angiogenesis is an extremely slow process. By contrast in certain disease states such as diabetic retinopathy, arthritis, chronic inflammation, hemangiomas, etc., angiogenesis persists and contributes to the pathology of these disease states. Some 50 such "angiogenic diseases" have been described where angiogeneSiS is involved. Also in tumor growth and metastasis angiogenesis is an essential process and precedes neoplastic transformation. Hence, angiogenesis could become an important diagnostic tool and a target for developing therapeutic agents. This book contains the proceedings of the NATO Advanced Study Institute on "Angiogenesis in Health and Disease" held in Porto Hydra, Greece, from June 16-27, 1991. This meeting was a comprehensive review of endothelial cell biology and endothelial cell phenotypic and functional heterogeneity in relation to angiogenesis under physiological and pathological conditions. Numerous in vitro and in vivo models were presented, which are used to study angiogenesis at the molecular and cellular levels and to evaluate chemical compounds or naturally occuring substances for their effect on angiogenesis. The presentations and discussions at this meeting provided an opportunity for the basic science and the clinical disciplines to meet, exchange information and provide future research directions for many investigators engaged in the study of angiogenesis.

Angiogenesis in Health, Disease and Malignancy

by Ali Salajegheh

This book is about “Angiogenesis”. A process in which new vasculature is formed from pre-existing capillaries. Angiogenesis process is associated with the proliferation and growth of both physiologically normal and neoplastic tissues, through the formation of vascular supply, essential for delivering growth requirements such as oxygen and nutrients.The book describes more than 100 genes and their key regulatory functions in the context of normal healthy condition, disease and malignancy, cancer proliferation and progression. New insights into the role of angiogenesis and the therapeutic inhibition of its regulators are investigated, due to the great potential for exploitation in the development of a novel treatment for cancer.New scientists, junior researchers and biomedical science students will find this book an invaluable introductory reference to their insight about angiogenesis and angiogenic role of more than 100 angiogenes and their role in healthy, disease and malignant conditions.

Angiogenesis Protocols (Methods in Molecular Medicine #46)

by J. Clifford Murray

In the last few years, we have been deluged with information on ang- genesis. Scientists and the public at large are exposed daily to this “new” science, not just in specialist journals and texts, but in the tabloid press, where popular articles refer to angiogenic therapies as magic bullets and miracle cures for cancer, arthritis, retinopathies, heart disease, and circulatory problems. Is there no ill this approach will not cure? The fact that so much time, effort, and resource have been and continue to be dedicated to this new science is clear testament to its importance. Yet many fundamental aspects of angiogenesis remain poorly und- stood, in particular cues that activate the process. This fact has to some extent been masked behind a surfeit of fine detail; we can’t see the wood for the trees. Most studies of angiogenesis identify single links in a long chain of events. Furthermore, each study is itself hampered by the limitations of the biological end-point chosen. For instance, though endothelial proliferation may well be necessary for angiogenesis, it is not sufficient. Therefore, measuring endothelial proliferation in response to a novel growth factor, and on the basis of this obs- vation, stating that the factor is “angiogenic,” is unsound logic. It is important that researchers in this field, and perhaps more importantly those experimenting at its periphery, recognize the limitations of their chosen biological end-points.

Angiogenesis Protocols (Methods in Molecular Biology #467)

by Stewart Martin and Cliff Murray

As experimentation and clinical trials with first generation anti-angiogenic agents have yielded results and our understanding of the biology and physiology of blood and lymphatic vessels has increased, a new angiogenesis volume swiftly became a necessity. Angiogenesis Protocols, Second Edition remains true to its original vision of providing a single source for angiogenesis researchers, irrespective of levels of resource and expertise, by collecting a range of methods for cell isolation and assessing angiogenesis in vivo or in vitro. This information, however, is expanded to include chapters on circulating endothelial progenitor cells, angiogenic signalling pathways, imaging of angiogenesis, and measurement of tissue blood flow. Written in the Methods in Molecular Biology™ series format, the chapters provide step-by-step laboratory protocols, lists of necessary materials and reagents, and a Notes section, which details tips on troubleshooting and avoiding known pitfalls. Extensive and cutting-edge, Angiogenesis Protocols, Second Edition is not only a practical handbook for key techniques, but also an informative and enjoyable read for all those interested, no matter how directly, in angiogenesis.

Angiography / Scintigraphy: Symposium of the European Association of Radiology Mainz 1–3 October, 1970

by L. Diethelm

The symposium on Angiography/Scintigraphy brought to Mainz in the fall of 1970 not only many European colleagues with an interest in these techniques, but also a number of visitors from overseas. These busy, work-filled days are beginning to fade in the memory of those who were there. Nevertheless, the scientific results reported on that occasion still supply the guidelines for what is currently being done in radiology and nuclear medicine. Anyone who has kept abreast of the literature over the past few years will have noted with some surprise how comparisons of the results obtained with these two important diagnostic aids continue to provoke controversy. One thing is certain: the emblem chosen for the Mainz symposium could hardly have been more appropriate. Like two cogwheels meshing in some complex piece of machinery, these radiological procedures demand the highest level of skill and precision before they will function properly on engaging so as to produce optimal results. Their findings complement each other in almost ideal fashion. Even though development in these two diagnostic disciplines has not exactly stood still since 1970, the papers given at this symposium established the fundamentals from which have stemmed many an intelligent adaptation of a method, many a cunning modification of an instrument and, not least, many a new research lead. This is why we applaud the initiative of Professor Diethelm of Mainz, whose brainchild this symposium was, in making the proceedings available to a wider audience.

Angiosperm Pollen and Ovules

by E. Ottaviano D. L. Mulcahy M. Sari Gorla G. Bergamini Mulcahy

The subject of this volume is the reproductive biology of plants. A steadily growing interest in this field is the result of at least two factors, as pointed out with great foresight by one of the driving forces in the field, H.E Linskens (Linskens 1964): most of the food consumed by humans takes the form of plant reproductive parts, and molecular biology now provides pow­ erful tools for investigating and manipulating plant reproductive systems. Molecular biology and the allied discipline of biotechnology are solidly represented in the papers in this book. The editors of Angiosperm Pollen and Ovules believe that the chapters herein contain some of the most excit­ ing findings of contemporary biology, and hope that the readers of this book will share their enthusiasm. The editors express sincere and grateful thanks for help from Carla Frova, Enrico Pe, and especially to Giorgio Binelli, all of the University of Milan. Without these three tireless and enthusiastic individuals it would not have been possible to maintain the apparently effortless proceeding of this congress. We thank also the organizing committee and the organizations that generously provided financial support (both listed below). Finally, we extend thanks to M. Cresti, D. Charlesworth, D. Hess, E Hoekstra, R. Bruce Knox, J.P. Mascarenhas, M.E. Nasrallah, P.L. Pfahler, A. Snow, and M.T.M. Willemse for chairing sessions.

Angiotensin Vol. I (Handbook of Experimental Pharmacology #163 / 1)

by Thomas Unger Bernward A. Schölkens

Nearly thirty years ago, in 1974, the volume on Angiotensin edited by Irvine H.Page and F. Merlin Bumpus expanded the Handbook of Experimental Pharmacology. Even after two decades the multiplicity of its actions appears not to have been fully discovered. To call attention to its many functions is one of the purposes of this book. This new edition of the volume on Angiotensin attempts to provide an updated account of the knowledge and findings accumulated since the complexity of angiotensin was so accurately recognized.

by Bernd Lohmann

Angle and spin resolved Auger emission physics deals with the theoretical and numerical description, analysis and interpretation of such types of experiments on free atoms and molecules. This monograph derives the general theory applying the density matrix formalism and, in terms of irreducible tensorial sets, so called state multipoles and order parameters, for parameterizing the atomic and molecular systems, respectively. It is the first book on angle and spin-resolved Auger emission.

Angle of incidence equals angle of reflection (large print)

by Rnib

This page shows a ray of light hitting a flat (plane) mirror at an angle and being reflected at the same angle. The diagram is labelled. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The mirror is seen in vertical cross section just to left of the centre of the page. The heavy vertical line represents its reflective surface. There is a dashed horizontal line, labelled normal, passing through the centre of the mirror. A line of arrows, representing an incident light ray, is going diagonally up and right from the bottom centre of the page. It hits the mirror at the normal line and is reflected up and left to the top centre of the page. An arc goes from the arrow at the bottom of the page, through the normal line, to the arrow at the top. This marks the angles of incidence and reflection. You can measure these angles by placing the centre of a protractor where the plane of the mirror crosses the normal line.

Angle Resolved Photoemission Spectroscopy of Delafossite Metals (Springer Theses)

by Veronika Sunko

This thesis describes the results of angle resolved photoemission spectroscopy experiments on delafossite oxide metals, and theoretical work explaining these observations. The study was motivated by the extraordinarily high conductivity of the non-magnetic delafossites PdCoO2 and PtCoO2, the measurement of whose electronic structure is reported and discussed. Two unexpected effects were observed in the course of the investigation; each is described and analysed in detail. Firstly, a previously unrecognised type of spectroscopic signal, allowing the non-magnetic probe of photoemission to become sensitive to spin-spin correlations, was observed in the antiferromagnetic PdCrO2. Its origin was identified as the Kondo-like coupling of itinerant and Mott insulating electrons. Furthermore, surface states exhibiting an unusually large Rashba-like spin-splitting were observed on the transition metal terminated surfaces of delafossites. The large inversion symmetry breaking energy scale, a consequence of the unusual structure of the surface layer, is identified as the origin of the effect.

Angle-Resolved Photoemission Spectroscopy on High-Temperature Superconductors: Studies of Bi2212 and Single-Layer FeSe Film Grown on SrTiO3 Substrate (Springer Theses)

by Junfeng He

This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8+δ (Bi2212) and single-layer FeSe film grown on SrTiO3 (STO) substrate by means of angle-resolved photoemission spectroscopy (ARPES). It provides the first electronic evidence for the origin of the anomalous high-temperature superconductivity in single-layer FeSe grown on SrTiO3 substrate. Two coexisted sharp-mode couplings have been identified in superconducting Bi2212. The first ARPES study on single-layer FeSe/STO films has provided key insights into the electronic origin of superconductivity in this system. A phase diagram and electronic indication of high Tc and insulator to superconductor crossover have been established in the single-layer FeSe/STO films. Readers will find essential information on the techniques used and interesting physical phenomena observed by ARPES.
