Available in PDF, EPUB and Kindle. Book excerpt: The progressive changes which occur during the life history of an individual metazoon are summed up under the term development. The adult multicellular organism differs from its early developmental stages by its size, shape, proportions, and by its parts having gradually acquired different structural and functional properties. Accordingly, several main processes involved in development, whose classification is a matter of convention, may be delimitated. Differentiation is considered one of the most important of them. In the broader sense of the word, the term differentiation is used for describing transformations, through which heterogeneity-at all levels (macroscopic, microscopic, submicroscopic)-arises or increases. The basic component of the wider phenomenon of differentiation is differentiation of cells, so-called cytodifferentiation. What is cytodifferentiation? In the course of ontogeny, the cells, starting with the fertilized ovum, via the blastomeres of the segmenting ovum and the germ layer cells, right to the differentiating and fully differentiated cells of tissues and organs, gradually acquire new properties which make them different both from a morphological and functional point of view. All changes involved in this process come under the term cytodifferentiation. Differentiation of cells (though not of all kinds of cells) continues throughout the entire life of the individual, but reaches its maximum at the embryonic period when it becomes the chief feature of development.

This book was released on 2012-12-06 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the development of cancer therapy has been marked by a recurring pattern, one of initially exciting and encouraging results as new methods were introduced, followed by dismaying failures. The extremity of the disease and its high mortality have dictated that each means of damaging tumor cells would be rapidly explored and exploited as a mode of therapy, long before the correspond ing theory and technique were completely understood and perfected. Thus radiation was used as an antitumor agent almost immediately following recogni tion of its cytodestructive capability. Equally constant, following the rapid utilization of new therapeutic methods, has been a period of significant technical improvements. This second aspect of the pattern is also illustrated by the field of radiotherapy. New radiation sources, new methods of dosimetry, use of high-energy radiation, and other new techniques allowed the therapist to better focus upon the tumor and to improve the geometry of exposure. Thus, with each technical advance, the "reach" of radiotherapy was increased and damage to normal tissues was decreased. Inevitably, however, a limit was reached, a point at which clinicians and researchers realized they could go no further without returning to a more fundamental search, one based on the biology of the tumor cell itself.
Download or read book Developmental Biology and Pathology written by A. Gropp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early development of the mammalian embryo belongs to a period which, for the student, provides the particularly deep fascination connected with the processes of germination of the fIrst tender buds of life. Moreover, developmental biology encompasses a very large part of biology; if broadly dermed - almost all of it. The same is true for the fIeld of pathology if the manifold possibilities of disorders of the orderly arranged pathways of developmental processes are considered. Normal development in its earliest steps - and it would be diffI cult to see it otherwise - means the functioning of very intricate systems of complex inter dependent cycles controlled by structural, genetic, physiological and biochemical determi nants. However, disturbances interfering with them in their very different ways, can lead to fetal death, disorders of growth and differentiation, malformation and disease, sometimes as late as in the next generation or later. This is, indeed, the concern of the pathologist to whom and to whose interest in developmental pathology, this book is dedicated. The outlines of the present volume were conceived at a symposium on "Control of early em bryogenesis and factors responsible for failure of embryonic development" held May 1-4, 1974 in Travemtinde and sponsored by the Deutsche Forschungsgemeinschaft. Almost fIfty active participants attended this conference. At the time and in keeping with the purpose of the conference, publication of the proceedings was not envisaged.
