Available in PDF, EPUB and Kindle. Book excerpt: 7 If so, the individual members of each class thus identified could then be subjected to a more profound pharmacokinetic analysis. In other words, we had to determine first which hormone protects against which drug, before we could explore how it did this. We had to know first that a hormone has adaptive value before we could ask whether this is due to a syntoxic or a catatoxic mechanism. Such observations, as the fact that an indomethacin-induced intestinal ulcer can be prevented by ethylestrenol, orthat cortisol aggravates certain infections, reveal nothing about how these hormones work; but only findings of this type can tell us where further research would be rewarding. Of course, scientists can rarely identify by direct observation the tbings that they are looking for; most of the time they have to be guided by indirect indices. The ebernist often first detects a compound, or even a particular functional group in its molecule, by inference from a color reaction, a revealing X-ray diffraction pattern or the formation of a characteristic precipitate. The physician must first suspect the presence of a microbe through certain clinical signs and symptoms before he can verify his diagnosis by looking for a particular organism. It is perhaps not too daring to hope that in our first efforts to clarify the role of hormones in resistance, simple, directly visible indicators might also serve us best.

Download or read book Aflatoxin written by Leo Goldblatt and published by Elsevier. This book was released on 2012-12-02 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aflatoxin: Scientific Background, Control, and Implications discusses general problems posed by mycotoxin contamination in foods and feeds. This book is divided into 15 chapters that summarize the discovery, elaboration, chemistry and assay, effects and metabolic fate, processing to ensure their removal or inactivation, and regulatory aspects of aflatoxins. The introductory chapters cover the discovery, formation by Aspergillus flavus, and the chemistry and structure of aflatoxins. The subsequent chapters describe the physicochemical and biological assays for aflatoxin measurement, detection, and analysis. A chapter also describes the metabolic fate and the biochemical alterations associated with aflatoxin administration to animals and other biological test systems. Discussions on the acute toxicity and carcinogenic activity of aflatoxins in laboratory and farm animals are also provided, with emphasis on the recognition of aflatoxicosis, a disease condition caused by the action of the aflatoxin poison. The book goes on examining the role of spoilage molds in destroying stored crops and the tremendous capacity for toxin production of aflatoxins. It also describes successful efforts of food and feed industries to ensure a wholesome food supply, including the utilization of various detoxification processes. The last chapters deal with the regulatory provisions for aflatoxin contamination control and tolerances and the implications of fungal toxins to human health. The book is intended for scientists and manufacturers concerned with the production and processing of foods and feeds, the nutrition, and the animal and public health.

Download or read book Plant Growth Substances 1970 written by D. J. Carr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the 6th International Conference on Plant Growth Substances, held in Carleton University, Ottawa in 1968, it was decided that the 7th should be held in Czecho slovakia, following an invitation by Dr. Kutacek. Historical events intervened and in 1969 another venue was sought. An offer from the Academy of Science in Canberra was accepted by the steering committee. This left rather less time than is desirable to organize an international meeting of this nature and it was with surprise and great relief that the Organizing Committee in Canberra welcomed the arrival of 183 delegates, including a relatively large overseas contingent, to the meeting in December, 1970. The aim of these Conferences is, of course, to provide a forum for discussion of new work and recent trends, both in the lecture sessions and in conversation. Although many of those who initiated these meetings (e.g. Skoog, Went, Blackman, Bennet-Clark) were absent from the Canberra conference - some have retired -it was good to see present so many of the new generation of research workers in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Cell Biology, A Comprehensive Treatise, Volume 3: Gene Expression: The Production of RNA’s mainly discusses the molecular and cytological bases of gene expression. The coverage begins with the concepts of organization of DNA and gene sequences in chromosomes, as an introduction to a more detailed coverage of gene expression. The book opens with a general discussion on the organization of DNA sequences in chromosomes. This chapter includes different methods of analyzing DNA sequences. As the book progresses, it looks upon the details on gene reiteration and amplification up to the transcription of prokaryotes and eukaryotes. It includes the ways of regulating transcription. The following chapters deal mostly with the structure and activity of genes up to the different virus strains in both RNA and DNA. The cytoplasmic and environmental impact on gene expression is also discussed. Chapter 8 generally tackles the DNA conformation and template function. The succeeding chapters focus on the transfer and ribosomal RNA as a result of maturation events; the processing of hnRNA and its relation to mRNA; and recombinant DNA procedures. The book closes with the directory of the different classes of cellular RNAs. This book will be helpful to many graduate students, teachers, scientists, and researchers in need of information regarding cell biology.
Download or read book Mechanisms of Hormone Action written by P Karlson and published by Elsevier. This book was released on 2013-10-22 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of Hormone Action: A NATO Advanced Study Institute focuses on the action mechanisms of hormones, including regulation of proteins, hormone actions, and biosynthesis. The selection first offers information on hormone action at the cell membrane and a new approach to the structure of polypeptides and proteins in biological systems, such as the membranes of cells. Discussions focus on the cell membrane as a possible locus for the hormone receptor; gaps in understanding of the molecular organization of the cell membrane; and a possible model of hormone action at the membrane level. The text also ponders on insulin and regulation of protein biosynthesis, including insulin and protein biosynthesis, insulin and nucleic acid metabolism, and proposal as to the mode of action of insulin in stimulating protein synthesis. The publication elaborates on the action of a neurohypophysial hormone in an elasmobranch fish; the effect of ecdysone on gene activity patterns in giant chromosomes; and action of ecdysone on RNA and protein metabolism in the blowfly, Calliphora erythrocephala. Topics include nature of the enzyme induction, ecdysone and RNA metabolism, and nature of the epidermis nuclear RNA fractions isolated by the Georgiev method. The selection is a valuable reference for readers interested in the mechanisms of hormone action.
