Book Description
This NATO-ASI on BIOPOLYMERS STRUCTURE AND DYNAMICS held between 22nd June 4th July 1986 at Erice (Italy) has brought together scientists from a broad variety of biophysical disciplines - polymer physics, biophysics and physical chemistry, structure and dynamics of polynucleotides, proteins, and polysaccharides - to present the current state of knowledge in their fields, both experimental and theoretical. This Advanced Study Institute was indeed a successfull attempt to enhance the possibility of intersection of a number of research lines that currently are progressing well but are still running largely in parallel with one another: protein folding, single-polymer phase transitions, DNA condensation into liquid crystalline-like arrays, packaging in viruses, and polysaccharide gel formation. Although each phenomenon is distinctive, an awareness of similarities may lead to new ic;leas. The program has emphasized "condensed" forms of biopolymers. We are universally confronted in biology by chain polymers folded on themselves or interlinked in gel-like assemblies, whether we look at the native structure of proteins, the role of polysaccharides in connective tissue, or the genetic apparatus. A number of lectures have been devoted to condensed forms of DNA - closed circular supercoils, toruses, chromatin.

Book Description
Polymers are essential to biology because they can have enough stable degrees of freedom to store the molecular code of heredity and to express the sequences needed to manufacture new molecules. Through these they perform or control virtually every function in life. Although some biopolymers are created and spend their entire career in the relatively large free space inside cells or organelles, many biopolymers must migrate through a narrow passageway to get to their targeted destination. This suggests the questions: How does confining a polymer affect its behavior and function? What does that tell us about the interactions between the monomers that comprise the polymer and the molecules that confine it? Can we design and build devices that mimic the functions of these nanoscale systems? The NATO Advanced Research Workshop brought together for four days in Bikal, Hungary over forty experts in experimental and theoretical biophysics, molecular biology, biophysical chemistry, and biochemistry interested in these questions. Their papers collected in this book provide insight on biological processes involving confinement and form a basis for new biotechnological applications using polymers. In his paper Edmund DiMarzio asks: What is so special about polymers? Why are polymers so prevalent in living things? The chemist says the reason is that a protein made of N amino acids can have any of 20 different kinds at each position along the chain, resulting in 20 N different polymers, and that the complexity of life lies in this variety.

Book Description
As optical fiber communication systems have moved out of the laboratory and into commercial use over the past several years, the general field of guided wave and coherent optics has undergone a radical transformation. Research in optical communication has turned heavily towards single-mode technology and, totally new phenomena and applications of the existing technology, outside the communication field, have begun to proliferate. It was for this reason that we decided to organize a NATO Advanced Study Institute assembling the leading workers in this new domain, in order to define the state of the art, and, develop an idea of the new directions the field might take. The lectures and seminars presented at this Advanced Study Institute form the basis for this book. The subjects treated can be roughly grouped as : - New phenomena in optical fibers such as non-linear effects, soliton propagation and polarization conservation. - New applications of fibers, to measurements of rotation pressure, temperature etc ... and medical uses. - Advanced and exploratory work on single-mode fiber communica tion systems including the use of coherent transmission schemes and optical amplification. - Recent developments of optical information treatment based on four-wave mixing. - Integrated optical devices and technologies including bistable devices, parametric oscillators, and optical logic. In addition to these major topics, a number of national reviews and specialized seminars treating new guided wave structures and materials are included. The co-editors admit being rather pleased with the result.

Book Description
‘‘Biopolymers’’ are polymeric materials of biological origin, including globular, membrane, and fibrous proteins, polypeptides, nucleic acids, po- saccharides, lipids, etc. and their assembly, although preference to respe- ive subjects may be different among readers who are more interested in their biological significance or industrial and/or medical applications. Nevert- less, characterizing or revealing their secondary structure and dynamics may be an equally very important and useful issue for both kinds of readers. Special interest in revealing the 3D structure of globular proteins, nucleic acids, and peptides was aroused in relation to the currently active Structural Biology. X-ray crystallography and multidimensional solution NMR sp- troscopy have proved to be the standard and indispensable means for this purpose. There remain, however, several limitations to this end, if one intends to expand its scope further. This is because these approaches are not always straightforward to characterize fibrous or membrane proteins owing to extreme difficulty in crystallization in the former, and insufficient spectral resolution due to sparing solubility or increased effective molecular mass in the presence of surrounding lipid bilayers in the latter.

Book Description
The content of this volume has been added to eMagRes (formerly Encyclopedia of Magnetic Resonance) - the ultimate online resource for NMR and MRI. The field of solid state NMR of biological samples [ssNMR] has blossomed in the past 5-10 years, and a cohesive overview of the technology is needed for new practitioners in industry and academia. This title provides an overview of Solid State NMR methods for studying structure dynamics and ligand-binding in biopolymers, and offers an overview of RF pulse sequences for various applications, including not only a systematic catalog but also a discussion of theoretical tools for analysis of pulse sequences. Practical examples of biochemical applications are included, along with a detailed discussion of the many aspects of sample preparation and handling that make spectroscopy on solid proteins successful. About EMR Handbooks / eMagRes Handbooks The Encyclopedia of Magnetic Resonance (up to 2012) and eMagRes (from 2013 onward) publish a wide range of online articles on all aspects of magnetic resonance in physics, chemistry, biology and medicine. The existence of this large number of articles, written by experts in various fields, is enabling the publication of a series of EMR Handbooks / eMagRes Handbooks on specific areas of NMR and MRI. The chapters of each of these handbooks will comprise a carefully chosen selection of articles from eMagRes. In consultation with the eMagRes Editorial Board, the EMR Handbooks / eMagRes Handbooks are coherently planned in advance by specially-selected Editors, and new articles are written (together with updates of some already existing articles) to give appropriate complete coverage. The handbooks are intended to be of value and interest to research students, postdoctoral fellows and other researchers learning about the scientific area in question and undertaking relevant experiments, whether in academia or industry.

Book Description
Biopolymers are a special class of polymers produced by living organisms. Starch, proteins and peptides, DNA, and RNA are all examples of biopolymers, in which the monomer units, respectively, are sugars, amino acids, and nucleic acids.A major but defining difference between polymers and biopolymers can be found in their structures. Polymers, including biopolymers, are made of repetitive units called monomers. Biopolymers inherently have a well defined structure: The exact chemical composition and the sequence in which these units are arranged is called the primary structure. Many biopolymers spontaneously fold into characteristic compact shapes (see also "protein folding" as well as secondary structure and tertiary structure), which determine their biological functions and depend in a complicated way on their primary structures. Structural biology is the study of the structural properties of the biopolymers. In contrast most synthetic polymers have much simpler and more random (or statistic) structures. This book presents leading-edge research from around the world in this dynamic field.
