Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - It has been ten years since the National Hormone and Pituitary Program (then called the National Pituitary Agency) sponsored a symposium on human growth hormone (hGH). Numerous advances have occurred during this period. This book does not attempt to summarize past achievements. Rather, it deals with the contemporary issues in hGH research. A discussion of the present state of the art, of necessity, includes a review of the past. Some of the topics herein discussed include the following: 1. Growth hormone releasing factor (GRF). In 1973, the growth hormone inhibitory factor (somatostatin) had recently been discovered. The search for a releasing factor in humans led to its discovery not in the pituitary but in a pancreatic tumor that secreted growth hormone. The advances are discussed in this book. The current hope is that GRF will eventually become an effective therapeutic agent for idiopathic hypopituitarism in childhood and adolescence. 2. Biosynthesis of hGR by recombinant DNA technology. Current advances are discussed. Although hGH is not yet an approved drug, it will eventually become one. This will broaden our horizons in terms of hGH effectiveness in disorders other than hypopituitary dwarfism. The current experience with this type of hGH in both the Vnited States and Europe is reviewed by several authors. …

[Bethe:] Pp. 434-456. [Oppenheimer & Volkoff:] Pp. 374-381. [Entire volume: 1300 pp.]. First printing of "ENERGY PRODUCTION IN STARS", Hans Bethe's seminal Nobel Prize winning paper on neucleosynthesis. It was the first time an astrophysical subject was recognized by the Nobel Committee. Bethe's work on nuclear reactions led him to discover the reactions that supply the energy in stars. In this paper, Bethe shows that "the most important source of energy in ordinary stars is the reactions of carbon and nitrogen with protons" (Bethe, Energy Production in Stars). Bethe began by analyzing the different possibilities for reactions by which hydrogen is fused into helium. He showed two processes to be the sources of energy generation capable of keeping stars hot. The first, the proton-proton chain, is the dominant energy source in stars with masses up to about the mass of the Sun. The second, the carbon-nitrogen-oxygen cycle, is the most important in more massive stars. "ON MASSIVE NEUTRON CORES" and NEUTRON STARS AND THE TOLMAN-OPPENHEIMER-VOLKOV LIMIT, two landmark papers which "for the first time laid a general relativistic theory of stellar structure" (Pais, Subtle is the Lord), thereby proving Einstein wrong in his conclusion that no star could collapse indefinitely.In the paper they addressed the question that Landau's paper, and also Oppenheimer and Serber's, had failed to consider: what is the maximum mass for stable neutron-star? This paper applied Tolman's method to calculate the gravitational equilibrium of a neutron star and predict the conditions under which it will continue collapsing into a black hole (the Tolman-Oppenheimer-Volkov Limit). The issue contain several other papers of interest: 1. Tolman, Richard. "Static Solutions of Einstein's Field Equations for Spheres of Fluid" - This paper developed a method for applying Einstein's field equations to static spheres of fluid in such a manner as to facilitate the development of exact solutions using known analytic functions)" Jenkins and Segre's "Quadratic Zeeman Effect" and "Zeeman Effect of the Forbidden Lines of Potassium" .2.
