Available in PDF, EPUB and Kindle. Book excerpt: A century has already passed since FRIEDRICH MIESCHER, working at Strasbourg and Basel, began his study of protamine, one of the basic nuclear proteins of cells. It was first established by KOSSEL that protamine represents the simplest known protein. In the conviction that research into the nature of protamine would shed light on that of other typical proteins, a group of researchers in Germany followed MIESCHER and laid the foundations of protein chemistry. A general view of prot amines was thus built up by KOSSEL, working at Strasbourg, Berlin, Marburg an der Lahn, and Heidelberg, FELIX at Heidelberg, Munich, and Frankfurt am Main, and WALDSCHMIDT-LEITZ at Prague and Munich. Concepts and techniques established by these studies have been widely utilized for research on other typical proteins. The revolutionary advances in chemical and physical techniques after W orId War II extended the sphere of research to Tokyo in the Far East. Prof. FELIX' visit in 1955 greatly encouraged our research group in Tokyo. His death in August 1960 constituted a sad loss to protein chemistry and stimulated our group to assume responsibility for carrying on the studies. In the following decade we in Tokyo have been able to add a new development to the results on the chemical structure of protamines accumulated by the Eurqpean researchers over a period of about fifty years.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive, up-to-date text, which brings together the key practical elements of the rapidly evolving field of sperm DNA and chromatin abnormalities, is divided thematically into five main sections. Part I discusses human sperm chromatin structure and nuclear architecture, while part II presents laboratory evaluation of sperm DNA damage, including SCSA, SCD, TUNEL and Comet assays, and cytochemical tests. Biological and clinical factors in the etiology of sperm DNA damage are discussed in part III, including oxidative stress, abortive apoptosis, cancer, and environmental and lifestyle factors. Part IV presents clinical studies on the utility of sperm DNA damage tests, both with natural and ART-assisted pregnancies, and debates the clinical utility of such tests. Finally, part V discusses current treatment options, such as antioxidant therapy, varicocelectomy, advanced sperm processing techniques and the use of testicular sperm. We are now beginning to better understand the unique organization of the sperm chromatin, as well as the nature and etiology of sperm DNA damage. Written and edited by worldwide experts in andrology, A Clinician's Guide to Sperm DNA and Chromatin Damage is an excellent resource for reproductive medicine and REI specialists, urologists, reproductive biologists and any professional working with the infertile male.

Download or read book Chemistry and Cytochemistry of Nucleic Acids and Nuclear Proteins written by Christoph Scholtissek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of nucleic acids has grown to such a tremendeous size that it is impossible to include all publications concerning the chemistry and biological role of nucleic acids in an article of the length presented in this "Volume. Therefore, it is necessary to select the most important contributions and those not included "in well-known reviews. In many cases reference is made only to the authors who summarized their specialized field in chapters of the three volumes of "The Nucleic Acids" (edB. E. CHARGAFF and J. N. DAVIDSON, Acad. Press, New York 1955 and 19(0) or to the "Nucleic Acid Outlines" (V. R. POTTER, Burgess Publishing Comp. Minneapolis), where further literature and more detailed discussions may be found. Facts and theories will be dealt with, but not lists of references. Therefore it is not possible to follow in all cases the historical development of an idea and to admowledge all publications which might be important and inter esting from another point of view. Very little is mentioned about methods in the field of nucleic acids.
Download or read book Chromosomal Proteins and Gene Expression written by Gerald R. Reeck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book stems from an Advanced Study Institute on Chromo somal Proteins and Gene Expression that was held in Sitges, Spain, on September 17-26, 1984. It would be misleading to call this volume a conference proceedings, however. The ASI was not a conference, but a course with diverse activities, only one of which was a set of major presentations by the lecturers. Indeed, the concept of lecturer was intentionally obscured as we all learned from each other through shorter presentations by other participants and through seminars, poster sessions, and small group discussions. Furthermore, many participants found that exchanging ideas outside organized sessions was among the most rewarding aspects of the course. Some even claimed to have profitably probed the intricacies of nucleosome structure and transcriptional regulation while basking in the sun on the beachl Obviously, it is difficult to catch the flavor of such varied proceedings in a book. (I cannot confirm the incident on the beach, never having found time to set foot there. Such is the fate of the director of a meeting. ) The ASI was judged a success -- and enthusiastically so - by most participants. Not only did we deepen our understanding of our scientific field, we made new friends and learned about scientific and nonscientific aspects of life in other countries and about issues that transcend international boundaries in our complex world. We hope that this volume will be as successful as the course was.

This book was released on 2012-12-06 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromosomes have structure, determined by the interactions of proteins with DNA, and chromosomes have functions, in particular, replication of DNA and transcription of messenger RNA. Chromosome structure and function are not separate topics, since chromosome organization pro foundly influences the activity of the genome in replication and transcrip tion. This is especially clear for higher cells, including human cells, in which chromatin fibers are created by the binding of histone proteins to the DNA, and folding of the fibers produces mitotic chromosomes and interphase nuclei. The intricate organization of DNA in higher cells is now recognized as being closely involved with genome activity. Many fundamental results have originated from studies of bacterial and viral systems, which have been systems of choice because of their less complex life cycles. The processes of replication and transcription show differences between the higher and simpler systems (e. g. , different enzymes and protein factors are involved). But the parallels are as striking as the differences in detail. Even for bacteria and viruses, a full understanding of these processes will require integrating the results of molecular biology with those of structural biology and cell biology. Three important subjects are covered in this volume: DNA replication and recombination, gene transcription, and chromosome organization. The sections dealing with replication and transcription examine recent results obtained by applying the techniques of molecular biology and biochemistry. Eukaryotic, prokaryotic, and viral systems are discussed.
