Biology of Invertebrate and Lower Vertebrate Collagens


Book Description

Knowledge in the field of the biology of the extracellular matrix, and in particular of collagen, has made considerable progress over the last ten years, especially in mammals, birds and ln man with respect to very important applied medical aspects. Basic knowledge in the animal kingdom overall has increased more slowly and haphazardly. We, therefore, considered it useful to organize a meeting specifically devoted to the study of the invertebrate and lower vertebrate collagens. The NATO Scientific Division financed an Advanced Research Workshop aimed at bringing together experts qualified in collagen biology (with morphological, biochemical and genetic specialization) with researchers who are currently studying collagenous tissues of invertebrates and lower vertebrates. The Medical-Biology Committee of the CNR-Rome and the University of Milan also supplied interest and support for the organization of this Meeting. The format of the workshop consisted in: 1) main lectures on the most recent aspects of collagen biology; 2) minireviews on the current knowledge of collagenous tissues in the various invertebrate phyla and in fish; 3) contributed papers on particular aspects of research in specific fields; 4) workshops on the methodology of studying collagen. As we had intended, the Workshop gave a comprehensive overview of acquired knowledge and of the present state of research actlvlty. It permitted wide interdisciplinary discussion, enabling collabora tions to be established and new research themes to be chosen. This volume contains the text of all the contributions presented at the Meeting, including posters.

Morphology, Molecules, Evolution and Phylogeny in Polychaeta and Related Taxa


Book Description

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.




Calcification in Biological Systems


Book Description

Calcification in Biological Systems provides a collection of up-to-date papers regarding calcification in a variety of biological systems. The papers are not simple reviews of the literature. Each paper reflects the personal experience of the author(s) and is rich in constructive criticism and suggestions. Topics range from basic molecular processes to general structural problems in systems as different as unicellular organisms and human skeletal tissues. Because calcification is so diffuse in the animal kingdom, this book makes no attempt to achieve a conclusive synthesis of available results and current ideas. Instead, its merit lies in its ability to be useful to investigators with different scientific backgrounds and areas of interest.




Epidemiology and Quantitation of Environmental Risk in Humans from Radiation and Other Agents


Book Description

The identification and quantitation of environmental risk in humans is one of the main problems to be solved in order to improve the protection of individuals and of human populations against phys ical and chemical pollutants. Epidemiology plays a central role in the evaluation of health risk directly in human populations. In this volume are collected 33 lectures presented at the AS! course on "Epidemiology and quanti tat ion of environmental risk in humans from radiation and other agents: potential and limitations", sponsored by NATO and Italian Association of Radiobiology and or ganized by ENEA. The course has been devoted to a number of aspects of environ mental risk analysis and evaluation based on epidemiological in vestigation. Basic epidemiological concepts and methods have been reviewed. Fundamentals of dosimetry and microdosimetry were presented in re lation to the contribution of epidemiology in defining the dose effect relationships for radiation carcinogenesis and its relation with age, sex and ethnicity. The mechanisms of carcinogenesis as a multi-stage process were illustrated. One of the main topics was 'cancer epidemiology' and its cor relation with: - occupational and non-occupational exposure to ra diation - diagnostic and therapeutic irradiation - cancer proneness - hereditary and familiar diseases - abnormal response to carcino gens - environmental pollution in air and water - exposure to radon in mines and in building material - atomic bomb explosion - chemo therapy - dioxin and related compounds.




Physiology of Molluscs


Book Description

Physiology of Molluscs: A Collection of Selected Reviews is an informative two-volume sent that brings together some of the most important recent and unique developments in molluscan physiology. Volume One focuses on shell structure, mineralization, the dynamics of calcium transport, shell drilling, byssus proteins, locomotion, and reproduction. Volume Two includes reviews on the neural mechanisms of learning, reproductive behavior, responses to environmental stress and hormones, and neurotransmitters. With the rapid development of cutting-edge proteomic, molecular biological, and cellular imaging techniques, our understanding of molluscan physiology, specifically in the areas of neurobiology, reproductive biology, and shell formation, has increased exponentially over the last several years. With contributions from some of the world’s leading experts in the field of molluscan physiology, this valuable two-volume set fills this void and will serve as an important resource for researchers, professors, and students. Chapters report on a variety of recent developments and new understanding, including • biology of byssus threads • physiology of reproduction in cephalopods • learning and memory of molluscs • endocrine disruption in molluscs • nautilus biology and behavior • cephalopod locomotion • neuronal circuitry in molluscs • reproductive endocrinology • bioactive peptides in molluscs The reviews in these two volumes will make a significant contribution to our understanding not only of molluscan physiology but also the physiology of animals in general.
