This book was released on 2013-06-29 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past twenty years the structure of the nuclear envelope, and in particular, that of its most distinct elements, the nuclear pore complexes, has been described from thin section electron microscopy (e, g., Brettschneider, 1952; Hartmann, 1953; Bahr and Beermann, 1954; Watson, 1954; Kautz and de Marsh, 1955; Watson, 1955), from metal-shadowed (e. g., Callan and Tomlin, 1950; Gall, 1954, 1956) and negatively stained (e. g., Franke, 1966, 1967; Gall, 1967; Yoo and Bayley, 1967) preparations of isolated nuclear membranes as revealing characte ristics common to euka. ryotic cells in general (recently reviewed, e. g., in Gouran ton, 1969; Stevens and Andre, 1969; Franke, 1970). In the recent years the freeze-etch technique (Steere, 1957) has proved to be a particularly useful tool in studying membraneous structures (e. g., Moor and Miihlethaler, 1963; Branton and Moor, 1964; Branton, 1966; Koehler, 1968b; Staehelin, l968a; Northcote, 1968a; Branton, 1969; Moor, 1969a). So this method has especially broadened the knowledge, e. g., on bacterial membranes (Bayer and Remsen, 1970; Nanninga, 1970), on erythrocyte plasma membranes (Weinstein and Bullivant, 1967; Meyer and Winkelmann, 1970; da Silva and Branton, 1970; Tillack and Marchesi, 1970), on liver cell membranes (Chalcroft and Bullivant, 1970), on Golgi membranes (Werz and Kellner, 1970; Staehelin and Kiermayer, 1970), on synaptic vesicles (Moor et al.

Download or read book Biophysics and Cancer written by Claudio Nicolini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early times of the Greek philosophers Leucippus and Democritus, and later of the Roman philosopher Lucretius, a simple, fundamental idea emerged that brought the life sciences into the realm of the physical sciences. Atoms, after various interactions, were assumed to acquire stable configurations that corresponded either to the living or to the inanimate world. This simple and unitary theory, which has evolved in successive steps to our present time, remarkably maintained its validity despite several centuries of alternative vicissitudes, and is the foundation of modern biophysics. Some of the recent developments of this ancient idea are the discovery of the direct relationship between spatial structures and chemical activity of such molecules as methane and benzene, and the later discovery of the three-dimensional structure of double-helical DNA, and of its relationship with biological activity. The relationship between the structure of various macromolecules and the function of living cells was one of the most striking advancements of modern science, obtained by the cooperation of physicists, chemists, mathematicians, engineers, biologists, and physicians. This crossing of the life and physical sciences has given rise to new and exciting frontiers, and to a new synthesis where there is a frequent interconnection of expertise, and where there is an exchange of roles among traditionally separated soft and hard sciences. Even if knowledge is still transmitted to new generations within univer sities as separate disciplines, new knowledge is acquired today in the laboratory by truly interdisciplinary teams.
Download or read book Advances in Biological and Medical Physics written by John H. Lawrence and published by Academic Press. This book was released on 2013-10-22 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Biological and Medical Physics, Volume 12 covers the significant progress in various aspects of biology and medical physics. This volume is composed of 16 chapters. The opening chapters deal with the principles and application of freeze-etching technique and scanning electron microscopy. The succeeding chapters review the development rudimentary model of the chromosome, the mechanisms involving large number of steps to kinetic studies of multisubstrate enzyme systems, and some biophysical approaches to evaluate radiation effects and their repair. These topics are followed by discussions the origin of the observed fluorescence and phosphorescence spectra of DNA, as well as some aspects of energy transfer that apply to DNA and other polynucleotides. Other chapters explore the processes of cellular repair, cell's radiation sensivity, bacterial photoreactivation of mutation, and the genetic control of DNA repair and genetic recombination. The final chapters consider the mechanism of mutation suppression in yeast, the role of cytoplasm in radiobiology, and the different random factors governing the dose-effect relation. This book is of value to biologists, medical physicists, and medical practitioners.
Download or read book Freeze Fracture Images of Cells and Tissues written by Richard L. Roberts and published by Oxford University Press, USA. This book was released on 1991 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The freeze fracture technique coupled with transmission electron microscopy has contributed significant scientific information toward the experimental investigation of both normal and abnormal cells in the fields of cellular, developmental and molecular biology, and to several subdisciplines in medicine, including pathology, anatomy, and physiology. This book presents a complete and up-to-date account of the macromolecular organization of membranes and the many membrane specialization of cells as well as overall cellular organization as reflected in tissues and organs. While the book emphasizes freeze fracture images and the useful scientific information contained in them, the authors have also included transmission electron micrographs of ultrathin sectioned cells, tissues, and organs in order to aid in the interpretation of the freeze fracture image and increase the book's utility. Where three dimensional views are particularly useful, scanning electron micrographs are included.
