Download or read book Advances in Morphogenesis written by M. Abercrombie and published by Academic Press. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Morphogenesis, Volume 2 considers the significant advances in various aspects of morphogenesis. This book is composed of nine chapters that cover the morphological and biochemical aspects of cell growth and development. The opening chapter deals with the principles and phenomena of morphogenesis characteristic of ciliate protozoa Stentor. The succeeding chapters examine the phenomena of symmetrization in amphibian, birds, reptiles, and fish, and discuss comparative biochemical studies on amphibian and invertebrate. These topics are followed by surveys on the histochemical and morpholopgical studies of limb morphogenesis in vertebrates. Other chapters are devoted to embryonic and larval development, as well as the regeneration in certain group of animals. This book is directed primarily to developmental biologists.

Download or read book The Biology of Stentor written by Vance Tartar and published by Elsevier. This book was released on 2013-10-22 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Download or read book The Molecular Biology of Ciliated Protozoa written by Joseph Gall and published by Elsevier. This book was released on 2012-12-02 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Molecular Biology of Ciliated Protozoa covers topics that are unique to ciliates, including major molecular progress, genetics, life history, and development of ciliates. Organized into 11 chapters, it focuses on the importance of ciliated protozoa as experimental organisms. The introductory chapter traces the ups and downs of ciliate biology, emphasizing the prominent role of the ciliates in early studies of cell structure, reproduction, and heredity. The book goes on to discuss ciliate genetics and conjugation, providing the basic biological framework for molecular studies of ciliate. Chapters 4 and 5 cover the nuclear DNA content, sequence, and arrangement of holotrichous and hypotrich ciliates. Chapters 6 to 9 examine the characterization of chromosomal telomeres, ribosomal gene amplification, and chromatin and histone structure using ciliated protozoa as experimental organisms. The final two chapters describe the mating mechanism of two ciliates, Blepharisma japonicum and Euplotes raikovi, and the function of surface antigens of Paramecium ciliate. The book is intended for students and investigators who want to learn more about the ciliated protozoa, particularly, in areas that cover fundamental features of eukaryotic biology.

Download or read book The Ciliated Protozoa written by John O. Corliss and published by Elsevier. This book was released on 2016-04-20 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ciliated Protozoa: Characterization, Classification and Guide to the Literature, Second Edition presents a premature major overhauling of the systematics of the Ciliophora sensu lato, which is considered a separate phylum. This book includes a developed rationale and defined criteria that serve as a basis for the reclassification of the ciliates. Discussions of controversial taxa are provided, including arbitrary but critical resolution of their place in, or rejection from, the new overall system. The ideas concerning the evolution of ciliates, as well as “phylogenetic trees are also covered in this text. This text categorizes the ciliates into three classes—Kinetofragminophora, Oligohymenophora, and Polyhymenophora. This publication is a good source for biologists and students interested in ciliates.

Download or read book Cilia Ciliated Epithelium and Ciliary Activity written by José A. Rivera and published by Elsevier. This book was released on 2013-10-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cilia, Ciliated Epithelium, and Ciliary Activity reviews the state of knowledge of the activity of cilia and of the role these structures play in maintaining the normal physiology of the body, especially in the respiratory and genital systems. It relates the diversity of manifestations shown by cilia and ciliated epithelium in health and disease, and the effect of the physicochemical agents studied which influence the life and death of these structures. The volume is organized into five sections. Section A provides a general discussion on the history of studies on the ciliated epithelium; the distribution and morphology of cilia; development, regeneration and transformation of ciliated cells; and culture of cilia and ciliated epithelium. Section B deals with ciliary activity while Section C examines the effects of physical and chemical agents on cilia. Section D takes up the function of cilia. Section E contains a list of references of the literature on these topics from the historical beginning of studies in the field to the time of writing. This volume is intended to be a ready-made reference source for workers in the fields of biological sciences and medicine.

Download or read book A Conceptual History of Modern Embryology written by Scott F. Gilbert and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Glory to the science of embryology!" So Johannes Holtfreter closed his letter to this editor when he granted permission to publish his article in this volume. And glory there is: glory in the phenomenon of animals developing their complex morphologies from fertilized eggs, and glory in the efforts of a relatively small group of scientists to understand these wonderful events. Embryology is unique among the biological disciplines, for it denies the hegemony of the adult and sees value (indeed, more value) in the stages that lead up to the fully developed organism. It seeks the origin, and not merely the maintenance, of the body. And if embryology is the study of the embryo as seen over time, the history of embryology is a second-order derivative, seeing how the study of embryos changes over time. As Jane Oppenheimer pointed out, "Sci ence, like life itself, indeed like history, itself, is a historical phenomenon. It can build itself only out of its past. " Thus, there are several ways in which embryology and the history of embryology are similar. Each takes a current stage of a developing entity and seeks to explain the paths that brought it to its present condition. Indeed, embryology used to be called Entwicklungsgeschichte, the developmental history of the organism. Both embryology and its history interpret the interplay between internal factors and external agents in the causation of new processes and events.

Download or read book Biochemistry of Differentiation and Morphogenesis written by L. Jaenicke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of this Mosbach Colloquium was meant as a question to begin with. When I started to study differentiation and morphogenesis in Volvox I hoped for a straightforward answer along prepared groove- only to find out that also here things follow Murphy's Law: they were much more complicated than expected! Succour had to be sought. Thus, the idea arose to put this question before a board of experts. Experience would have warned any ex-service man never to utter an idea or else you would be made responsible, and it came as it had to come: I was made impressario of this gremium; I had to assemble the experts. These Proceedings contain their expertise. I cannot even say that I biased it by my picking. In the beginning I aimed at setting different accents by inclination and force of habit. Then, by trial and error, by advice and declination, the programme shaped itself. It eventually gained momentum of which also the size of this volume is indicative. In this volume are printed all the papers presented - with two regret ted exceptions - but not the sometimes lively discussion, which clari fied and pruned here and there. It would just have made the size too unwieldy. Differentiation and morphogenesis start with the expression of genes. The development programme reels off the genome and is regulated by the position of the appropriate genes. Their structure is in the focus of gene biochemistry since the decisive tools have become available.
