Comparative Organellography of the Cytoplasm by Albert Frey-Wyssling Pdf

Since the publication of my monograph "Die submikroskopische Struktur des Cytoplasm as" [Protoplasmatologia III A12 (1955)], science has increased our knowledge on this cell constituent in an amazing way. At that time, cytoplasm was still considered as an amorphous colloid with an amicroscopic structure capable of sol/gel transformations. Meanwhile, within the past 18 years, ultrastructure research and molecular biology have shown that it consists of structured organelles, thereby revolutionizing our concept of the cytoplasm. There is an ontogeny of these organelles which deals with their appearance, development, growth and eventual disappearance. Although the results of relevant studies are less spectacular at this time than those concerning nucleic acids, they will become more and more important in the near future, because they touch the basic question of how molecular morphogenesis is realized. Therefore, an attempt is made to portray the actual state of these problems from a biological point of view which involves a comparison of the established organelles. I thank Miss SONIA TURLER and Dr. ELsA HAUSERMANN for their help with the manuscript and my former pupils and assistants Drs. Kopp, KUHN, SCHWARZENBACH, STAEHELIN, STEINMANN, and VOGEL, as well as my colleagues Professors MATILE, MooR, and MUHLETHALER for original electron micro graphs.

Oocyte Growth and Maturation by T.A. Dettlaff,Sergei G. Vassetzky Pdf

Studies of oogenesis occupy an important place in current in vestigations in developmental biology. Today no one has any doubt whatsoever that oogenesis is not just the prelude to development, but is development itself, and a very essential part of it. These words of an eminent Soviet scientist, B. L. As taurov , taken by T. B. Aizenshtadt as an epigraph to her chapter in this book, make a good epigraph for the entire book. It is now clear that during oogenesis not only vast reserves of ribosomes and mitochondria, of yolk, carbohydrates, and lipids, and of enzymes for protein and nucleic acid synthesis and for carbohydrate and fat metabolism (which ensures the energy supply and metabolism of the oocyte and the developing embryo) are formed, but also long-lived mRNA and proteins are synthesized, which determine both the completion of oocyte maturation and the initial stages of embryonic development. In the last 15-20 years, the use of molecular biology methods, electron microscopy, autoradiography, and microsurgical methods of experimental embryology in studying the pre-embryonic development of animals has greatly increased our knowledge of oogenesis. This has led to the need to systematize the data obtained, to reinter pret old ideas, and to review the results obtained by new research trends which have emerged in the last few years and which are of general biological interest. Such a task was undertaken in the book Sovremennye Problemy Oogeneza (Current Problems of Oogenesis), published in 1977 (in Russian).

Atheist Persona by John J. Pasquini Pdf

Atheist Persona is a summary of the most recent research on the subject of atheism. In an effort to create a more courteous dialogue between theists and atheists, this book acknowledges that while there are reasons for believing in God, there are also reasons for not believing in God.

Transport in Plants I by M.H. Zimmermann,J.A. Milburn Pdf

When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Structure and Function of the Gonadotropins by Kenneth W. McKerns Pdf

In September of 1977 scientists from many countries met at the Asticou Inn in Maine to present and discuss papers written especially for this monograph. The presentations were informal and directed to the special interests of the audience in order to generate discussions. The authors, many of whom are pioneers and leaders in their field, then had the oppor tunity to revise their contributions, which were brought together with the edited discussions to form this volume. The basic research studies presented here are important because of the essential role of gonadotropins in regulating the ovary and testis. This monograph will therefore be of interest to those concerned with fertility regulation, population control, possible new methods for contraception, and to those concerned with reproduction in domestic animals. Re searchers in other fields may find this monograph useful, as it has been de termined that gonadotropins are secreted by many tumors and are im plicated in many cancers. Human choriogonadotropin also seems to be found in most, if not all, cells of the human body. The significance of this, however, is unknown.

The Excretory Function of Higher Plants by Victoria V Roshchina,Valentina D. Roshchina Pdf

The secretory activity of plants is a manifestation of the fundamental property of all living organisms: the ability to exchange substances and energy with the environment. This book summarizes today's knowledge of all such secretory activities of higher plants. It equally considers the cellular aspects, intratissular and external secretion, gas excretion and the excretion of substances under extreme conditions as well as the biological effects of plant excreta.
