This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The building of conceptual models is an inherent part of our interaction with the world, and the foundation of scientific investigation. Scientists often perform the processes of modelling subconsciously, unaware of the scope and significance of this activity, and the techniques available to assist in the description and testing of their ideas. Mathematics has three important contributions to make in biological modelling: (1) it provides unambiguous languages for expressing relationships at both qualitative and quantitative levels of observation; (2) it allows effective analysis and prediction of model behaviour, and can thereby organize experimental effort productively; (3) it offers rigorous methods of testing hypotheses by comparing models with experimental data; by providing a means of objectively excluding unsuitable concepts, the development of ideas is given a sound experimental basis. Many modern mathematical techniques can be exploited only with the aid of computers. These machines not only provide increased speed and accuracy in determining the consequences of model assumptions, but also greatly extend the range of problems which can be explored. The impact of computers in the biological sciences has been widespread and revolutionary, and will continue to be so.

This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: My introduction to androgens was neither auspicious nor impressive. I was sitting my viva voce examination for a degree in physiology and had haltingly intimated to my examiner (name decorously withheld) that I intended to pursue a career in re search. "On what topic?" was the reply. I had been deeply impressed by the work of C. Huggins and C. V. Hodges (Cancer Res. 1, 293, 1941) on the dramatic arrest of canine prostatic hyperplasia by the administration of stilboestrol. With some en thusiasm, I responded, "On steroid hormones, because I am struck by the profound effects that may be achieved by relatively small numbers of molecules. " The examiner sank into deep contemplation before replying, "Young man, have you considered go ing into teaching?" Suitably chastened, I finally began my research career investigating the effects of steroids on the nucleic acid metabolism of experimental tumours and on the process cells. Reaching an impasse in this work, I mentioned one of senescence in animal day to Dr. G. F. Marrian that, somewhat surprisingly, we had no understanding of the fundamental mechanism of action of steroid hormones, especially the androgens. me to tackle this problem, particularly since exciting new insights He encouraged were then being made into the interaction of radioactively labelled oestradiol-l?,8 with such tissues as rat uterus.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this monograph is to describe theoretical aspects of the interpretation of data obtained from experiments performed with labeled hormones. Quantitative endocrinologic studies involving the use of tracers include the determination of rates at which hormones are secreted by endocrine glands and are produced outside these glands by conversion of other secreted hor mones. Tracer experiments are also performed with the purpose of measuring rates of metabolic reactions. These measurements reveal the contribution of secreted hormones to the formation of circulating compounds and urinary metabolites. The estimation of rates of fetal and placental production and exchange of hormones characterizes a class of in vivo quantitative studies performed with isotopically labeled hormones (radioactive or not). In addi tion, tracers are used to measure permeability and rates of reaction in in vitro systems, and to study the uptake of hormones by tissues, both in vivo and in vitro. The stability of the steroid nucleus carrying the isotopic label and the large number of reversible metabolic reactions in which steroids are involved, both facilitated and motivated the development of a sophisticated theoretical treat ment of tracer experiments in the field of endocrinology. Although the prac tical examples used to illustrate the concepts and calculations presented in this monograph involve labeled hormones, the theory is presented in a general symbolic manner and is applicable to other fields of investigation.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade we have witnessed a revolution in analytical methods. The development of vapor phase chromatography for the separation and analysis of classes of substances ranging from metals and gases to a wide variety of organic materials has been one of the most exciting of these new techniques. Gas-liquid chromatography for the measurement of steroids is particularly significant for endocrinologists and reports during the past several years have demonstrated its usefulness. Because of the growing interest in this method, a committee of the Endocrinology Study Section composed of Drs. R. M. Dodson, Seymour Lieberman, Hilton A. Salhanick, and Ralph E. Peterson, felt that the time was propitious to hold this Workshop and it is on their behalf that I welcome you. We hope to obtain enough data during these sessions so that those attending this conference and those who may read the proceedings will be able to make an informed judgement about the usefulness of gas-liquid chromatography for the analysis of steroids in biological fluids. Thus, I hope that there will be adequate documentation of the reliability of the methods as well as a comparison of the advantages and disadvantages of this analytical method with other classical methods. If we can do this, this Workshop will provide a significant base of practical considerations about gas chromatographic analytic techniques. I would like to thank Drs. T. F. Gallagher, H. Wilson, H. Salhanick and L. Engel for agreeing to serve as Chairmen of the sessions.
