Biogenesis of Antibiotic Substances

 

Academic Press, 1965.

ISBNs 9780123955241

Colección: ScienceDirect

Resumen (en inglés): Biogenesis of Antibiotic Substances covers the proceedings of a panel discussion on ""Basic Research and Practical Aspects of Antibiotic Production"" held during the Antibiotic Congress in Prague. This book is organized into 25 chapters that cover the regulating mechanisms of primary antibiotic metabolite biosynthesis. This text describes the relationship between secondary metabolite production and synthesis of cell matter or cell wall.
The opening chapters describe the parasexual cycle and some of the ways in which the cycle may be used for strain improvement, as well as the applications of refined techniques of genetic recombination and the principles of biochemical genetics to the field of antibiotics. The next chapter deals with cultural and fermentative characteristics of A-type isolates obtained from progenitor and representative member strains of the Wisconsin Family of Strains of Penicillium chrysogenum. Considerable chapters are devoted to the metabolite biosynthesis, such as geodoxin and related compounds; secondary metabolism of penicillins, gibberellins, and griseofulvin in fungi; and tetracycline metabolites. The book goes on examining the stereochemical aspects of macrolide antibiotics. It also describes the biosynthetic pathways involving ring cleavage of carbocyclic compounds, as well as the biosynthesis of different peptide antibiotics and of actinomycins and its relationship to protein synthesis. The production of phenazines is also explained. Other chapters consider other metabolites, such as those that decarboxylate, the malonate, and the 3-nitropropionic acid. A discussion on the role of carbohydrates and phosphate in the biosynthesis of different types of antibiotics is included. Lastly, microbiological assay procedures for antibiotic research and influencing factors are presented.

Biological Applications of Liquid Scintillation Counting

 

Academic Press, 1974.

ISBNs 9780124172500

Colección: ScienceDirect

Resumen (en inglés): Biological Applications of Liquid Scintillation Counting, based on a series of lectures given at the Worcester Foundation for Experimental Biology, discusses the various biological applications of liquid scintillation counting and presents its principles in a manner that is simple, practical, and useful. This book explains the fundamentals of scintillators and the scintillation process, from sample preparation to testing and setting up a counter and the application of radiotracers.
This text is organized into six chapters and begins with a historical overview of liquid scintillation counting, emphasizing two major events that stimulated its development: the discovery of organic compounds called ""scintillators"" and the introduction of photomultiplier tubes. This book considers the factors that affect the performance of photomultiplier tubes, including temperature and magnetic fields, and the use of liquid scintillation counting to measure radioactivity. The discussion then shifts to the factors that must be taken into account when choosing a method for preparing samples, including the physical and chemical characteristics of the sample, the isotope or isotopes of the sample, and the anticipated level of radioactivity. The following chapters look at the general considerations when installing a liquid scintillation counter, procedures for applying radiotracers, and practical aspects of sample preparation.
This book is intended for physicists and experimental biologists.

Biological Applications of Magnetic Resonance

 

Academic Press, 1979.

ISBNs 9780126407501

Colección: ScienceDirect

Resumen (en inglés): Biological Applications of Magnetic Resonance discusses various applications of magnetic resonance techniques. The book's opening chapter examines the exchange behavior of the hydrogen-bonded protons and its influence on their nuclear magnetic resonance (NMR) spectra. This is followed by separate chapters dealing with NMR studies of nucleic acid and drug-nucleic acid complexes. Aspects of the basic theory of the nuclear Overhauser effect (NOE) are presented, along with applications of NOEs observed for protons in biomolecules. Subsequent chapters cover specialized EPR techniques that have been applied to biological problems; the use of physical methods to refine a model of the combing site of the Fv fragment of protein 315; and the utility of model compounds in the analysis of hemoprotein NMR spectra. The remaining chapters discuss serine proteinases that have been investigated by nuclear magnetic resonance spectroscopy; the use of NMR in the study of intact living tissue and organs; and 31P and 13C NMR studies of E. coli cells.

Biological Approaches and Evolutionary Trends in Plants

 

Academic Press, 1990.

ISBNs 9780124029606

Colección: ScienceDirect

Resumen (en inglés): Biological Approaches and Evolutionary Trends in Plants is a collection of papers presented at the Fourth International Symposium of Plant Biosystematics held on July 10-14, 1989 in Kyoto, Japan. Contributors, some are world's leading plant biologists, discuss the findings in evolutionary biology and issues in plant biosystematics in light of the evidence and ideas brought forward at various levels of biological organization, from molecule to cell, individual, population, species, and community levels.
This volume is organized into four sections encompassing 22 chapters and begins with an overview of discoveries concerning parapatric differentiation of weed populations, including adaptive evolution in herbicide resistant biotypes and complex evolutionary patterns in weed-crop complexes of various groups. The next section explores molecular approaches in plant biosystematics, focusing on amino acid sequencing of proteins; restriction-site variations of cpDNA, mitDNA, rDNA, etc.; and chromosome-banding patterns revealed by differential staining. The discussion shifts to a wave of research in plant population biology and evolutionary ecology since the 1970s and its impact on biology and biosystematics. The book considers various aspects of reproductive biology and evolutionary changes in significant reproductive parameters and attempts to demographically quantify these parameters. The final chapter is devoted to the use of functional phylogenetic systematics for predictive ecology.
This book will be of interest to plant biologists and scientists and researchers in fields such as biochemistry, botany, microbiology, ecology, and evolutionary biology.

Biological Effects of Radiations

 

2nd ed. Academic Press, 1979.

ISBNs 9780123041500

Colección: ScienceDirect

Resumen (en inglés): Biological Effects of Radiation, Second Edition aims to present an organized survey of the various experiments wherein living materials have been exposed to ionizing and exciting types of radiations. However, this book focuses on the effects of radiation to lower organisms, as these have received less attention. It tells how small amount of energy can damage submicroscopic structure and ultimately alter the appearance and abilities of such organisms.
Divided into five parts, this book starts off with two introductory chapters in the first part. It explains the effects of radiation. Then, other parts of the book focus on the impact of radiation from cellular to organ level. How the lower organisms response is then discussed. Lastly, the book explains the interrelations between organisms in contaminated areas. Same with the first edition, emphasis is given on the consequences of mutations, as a whole chapter is devoted to this topic. Furthermore, this book covers discoveries from experiments with cultured cells.
This book is a good text-reference for students and professionals. Also, it can be of great help to scientists, researchers, and specialists involved in the biological response to radiation.
