Book Description
Information concerning localization of exogenously administered tritiumlabeled steroid hormones in the brain by dry-mount autoradiography was presented. Estrogens, androgens, and glucocorticoids were found to be concentrated and retained in nuclei of certain neurons. The autoradiographic information on the topographic distribution of hormone-neurons (neurons which concentrate, retain, and respond in a specific manner to hormones) suggested that "feedback" areas for the regulation of endocrine glands are not restricted to the hypothalamus and preoptic region. It appeared that gonadotropin and neurons that regulate sexual behavior were widespread within the phylogenetically ancient periventricular brain, following the origin, the termination, and to some degree, the path of certain nerve-fiber tracts. In the case of estradiol and androgen, likely to be involved are the stria terminalis, the ventral amygdalohypothalamic pathway, a portion of the fornix, the periventricular bundle, and others. Hormone-neurons have been found only in the periventricular brain but not in the neopallium. It was concluded that the "hypophysiotropic area" is probably not restricted to a limited hypothetical segment of the hypothalamus but is identical with the multiple sites of autoradiographically defined hormone-neurons within the phylogenetically older periventricular brain.
Asymmetric Synthesis V3
Author: James MorrisonPublisher: Elsevier
ISBN: 0323145000
Category : Science
Languages : en
Pages : 593
Book Description
Asymmetric Synthesis, Volume 3: Stereodifferentiating Addition Reactions, Part B presents intensive investigations in leading academic and industrial laboratories on stereodifferentiating addition reactions. This book is divided into eight chapters and begins with a comprehensive review of the formation of chiral metal enolates and their stereoselective alkylation reactions. These topics are followed by discussions on chiral Aldol addition reactions and the many variations of asymmetric synthesis that may be carried out using chiral oxazolines. A chapter describes the alkylation of chiral hydrazones, a process that yields chiral-substituted aldehydes and ketones. Other chapters explore a variety of cyclization processes that form carbon-carbon and carbon-heteroatom bonds. The last chapters deal with the asymmetric cycloadditions and sigma-tropic rearrangements. Synthetic chemists and researchers will find this book invaluable.

Book Description
Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.
