Available in PDF, EPUB and Kindle. Book excerpt: In the field of biological studies, next to the standard methods, new tools are offered by contemporary physics. X-ray spectroscopic techniques enable probing electronic structure of occupied and unoccupied states of studied atom and distinguish the oxidation state, local geometry, and ligand type of elements that occur in biological material. Direct analysis using X-ray spectroscopy avoids many chemical preparation steps that might modify biological samples. The information obtained gives us insight into important biochemical processes all under physiological conditions. In this chapter we focus our attention to the application of X-ray spectroscopy to the study of biological samples, with special emphasis on mechanisms revealing interaction between DNA and different cytotoxic agents and in the determination of changes in oxidation state of different elements in pathologically altered human cells and tissue.

Download or read book X ray Scattering written by Alicia Esther Ares and published by BoD – Books on Demand. This book was released on 2017-01-25 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray scattering techniques are a family of nondestructive analytical techniques. Using these techniques, scientists obtain information about the crystal structure and chemical and physical properties of materials. Nowadays, different techniques are based on observing the scattered intensity of an X-ray beam hitting a sample as a function of incident and scattered angle, polarization, and wavelength. This book is intended to give overviews of the relevant X-ray scattering techniques, particularly about inelastic X-ray scattering, elastic scattering, grazing-incidence small-angle X-ray scattering, small-angle X-ray scattering, and high-resolution X-ray diffraction, and, finally, applications of X-ray spectroscopy to study different biological systems.

This book was released on 2012-12-06 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1997 European Conference on Spectroscopy of Biological Molecules (ECSBM) is the seventh in a biennial series of conferences devoted to the applications of molecular spectroscopy to biological molecules and related systems. The interest of these conferences rests mainly on the relationship between the structure and physiological activity of biological molecules and related systems of which these molecular species form part. This volume ofECSBM contains articles prepared by the invited lecturers and those making poster presentations at the seventh ECSBM. The reader will find mainly applications of vibrational spectroscopy to protein structure and dynamics, biomembranes, molecular recognition, nucleic acids and other biomolecules and biological systems containing specific chromophors. Biomedical applications of vibrational spectroscopy are expanding rapidly. On the other hand, a significant number of the papers describe applications of other methods, such as NMR, circular dichroism, optical absorption and fluorescence, X-ray absorption and diffraction and other theoretical methods. One aim has been to achieve a well balanced, critically comparative review of recent progress in the field of biomolecular structure, bonding and dynamics based on applications of the above spectroscopic methods. A great part of the contributions included in this volume are devoted to biomedical and biotechnological applications and provide a broadly based account of recent applicationS in this field. The content of this book has been organized in sections corresponding mainly to the different types of biological molecules investigated. This book includes also another section related to theoretical methods where MO calculations of vibrational frequencies dominate clearly the topic.

Discussions on the use of inner-shell signals for a quantitative local microanalysis technique; theoretical study of the energy resolution; and collection efficiency of a magnetic spectrometer are also included. The final part covers the elemental distribution in single erythrocytes using X-ray microanalysis. It also discusses the fundamentals of cryosectioning process for X-ray microanalysis of diffusible elements and the freezing behavior of a number of chemically different gels chosen for their partial resemblance to biological structures. Considerable chapters contain materials and methods, results, discussions, conclusions, and references.
