Book Synopsis Computer Simulation in Cell Radiobiology by : Andrej Yu. Yakovlev
Download or read book Computer Simulation in Cell Radiobiology written by Andrej Yu. Yakovlev and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research monograph demonstrates the possible ways of using stochastic simulation for exploring cell kinetics, emphasising the effects of cell radiobiology. In vitro kinetics of normal and irradiated cells is the main subject, but some approaches to the simulation of controlled cell systems are considered as well: the epithelium of the small intestine in mice taken as a case in point. Of particular interest is the evaluation of simulation modelling as a tool for gaining insight into biological processes and hence the new inferences from concrete experimental data, concerning regularities in cell population response to irradiation. The book is intended to stimulate interest among computer science specialists in developing new, more efficient means for the simulation of cell systems and to help radiobiologists in interpreting the experimental data. The reader is expected to be acquainted with fundamentals of the theory of probability and stochastic processes. Applications are addressed to a biologically educated reader.

This book was released on 2009-06-05 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to two important aspects of modern bioch- istry, molecular biology, and biophysics: computer simulation and data analysis. My aim is to introduce the tools that will enable students to learn and use some f- damental methods to construct quantitative models of biological mechanisms, both deterministicandwithsomeelementsofrandomness;tolearnhowconceptsofpr- ability can help to understand important features of DNA sequences; and to apply a useful set of statistical methods to analysis of experimental data. The availability of very capable but inexpensive personal computers and software makes it possible to do such work at a much higher level, but in a much easier way, than ever before. TheExecutiveSummaryofthein?uential2003reportfromtheNationalAcademy of Sciences, “BIO 2010: Transforming Undergraduate Education for Future - search Biologists” [12], begins The interplay of the recombinant DNA, instrumentation, and digital revolutions has p- foundly transformed biological research. The con?uence of these three innovations has led to important discoveries, such as the mapping of the human genome. How biologists design, perform, and analyze experiments is changing swiftly. Biological concepts and models are becoming more quantitative, and biological research has become critically dependent on concepts and methods drawn from other scienti?c disciplines. The connections between the biological sciences and the physical sciences, mathematics, and computer science are rapidly becoming deeper and more extensive.

This book was released on 2013-11-11 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Office of Health and Environmental Research (OHER) has supported and continues to support development of computational approaches in biology and medicine. OHER's Radiological and Chemical Physics Program initiated development of computational approaches to determine the effects produced by radiation of different quality (such as high energy electrons, protons, helium and other heavy ions, etc. ) in a variety of materials of biological interest-such as water, polymers and DNA; these include molecular excitations and sub-excitations and the production of ionization and their spatial and temporal distribution. In the past several years, significant advances have been made in computational methods for this purpose. In particular, codes based on Monte Carlo techniques have ·been developed that provide a realistic description of track-structure produced by charged particles. In addition, the codes have become sufficiently sophisticated so that it is now possible to calculate the spatial and temporal distribution of energy deposition patterns in small volumes of subnanometer and nanometer dimensions. These dimensions or resolution levels are relevant for our understanding of mechanisms at the molecular level by which radiations affect biological systems. Since the Monte Carlo track structure codes for use in radiation chemistry and radiation biology are still in the developmental stage, a number of investigators have been exploring different strategies for improving these codes.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting the biological effects induced by ionizing radiation is a major scientific challenge of current radiobiology, in particular to try to better understand the effects of low doses on living beings as well as carcinogenesis. The computational approach based on codes to simulate trace structures in the biological medium using the Monte Carlo technique is today the most reliable method to calculate the early effects of ionizing radiation on DNA, the main cellular target of radiation effects. Among the existing codes, the Geant4-DNA extension of the Geant4 general purpose simulation toolkit is the first one fully open and freely available to the community. Geant4-DNA can simulate not only the physical but also the physico-chemical and chemical stages of water radiolysis. These stages can be combined with simplified geometric models of DNA to assess direct and indirect early DNA damage. In this thesis, I propose (1) to improve in Geant4-DNA the modeling of the elastic scattering of electrons in liquid water in order to simulate more precisely the spatial distribution of energy deposits and radical species. Then, (2) the physico-chemical stage of water radiolysis is also improved based on approaches described in the literature (modeling, measurements), this step strongly affecting the chemical stage by modifying the initial yields and the concentration of radical species. (3) In addition, the Independent Reaction Time (IRT) method is implemented in Geant4-DNA to reduce the computational time to simulate the chemical kinetics of water radiolysis. Finally, I evaluate (4) the biological damage induced at the subcellular scale using a cellular DNA geometry developed in a previous study, including in the simulation all the improvements developed during this thesis, up to the repair of early DNA damage. These developments are grouped in a complete simulation chain for users of the Geant4-DNA extension of Geant4.

Available in PDF, EPUB and Kindle. Book excerpt: From the preface by Joel E. Cohen: "A century from now humanity will live in a managed - or mismanaged - global garden. We are debating the need to preserve tropical forests. Farming of the sea is providing an increasing part of our fish supply. We are beginning to control atmospheric emissions. In 100 years, we shall use novel farming practices and genetic engineering of bacteria to manipulate the methane production of rice fields. The continental shelf will be providing food, energy, possibly even living space. To make such intensive management possible will require massive improvements in data collection and analysis, and especially in our concepts. A century hence we will live on a wired earth: the oceans and the crust of the earth will receive the same comprehensive monitoring now devoted to weather. As the peoples of currently developing countries increase their levels of wealth, the need for global management will become irresistible as impatience with the accidents of nature and intolerance of mismanagement of the environment - especially of living resources - grow. Our control of physical perturbations and chemical inputs to the environment will be judged by the consequences to living organisms and biological communities. How can we obtain the factual and theoretical foundation needed to move from our present, fragmented knowledge and limited abilities to a managed, global garden?" This problem was addressed in the lectures and workshops of a summer school on patch dynamics at Cornell University. The school emphasized the analysis and interpretation of spatial patterns in terrestrial and marine environments. This book contains the course material of this school, combining general reviews with specific applications.
Book Synopsis Principles of Surgical Oncology by : Ronald Raven
Download or read book Principles of Surgical Oncology written by Ronald Raven and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis during the present decade of different arts and sciences to form oncology as a mUltidisciplinary subject is of profound importance for coordinating the clinical and research efforts to control a number of diseases that cause high mortality and morbidity in the human race and to elucidate their causation. These diseases traditionally have been grouped together under the general term of cancer, without any scientific reason and irrespective of many differences existing between them. The word cancer, because it is synonymous with diseases that cause suffering and death, naturally generates fear in people throughout the world. Cancer fortunately has a changing face caused by the realization that these diseases are different diseases with variable etiology and prognosis; they need different kinds of treatment, and even prevention is a practical proposition. The time has therefore come to delete the term cancer from our terminol ogy as unscientific and unhelpful and to substitute oncological diseases governed by the system of knowledge designated oncology. This conforms also with the designations used for other groups of diseases. In the divisions of oncology an important place is held by surgical oncology because many oncological diseases require surgical treatment alone, or in combination with radiotherapy and chemotherapy. Combina tion therapy is being used effectively for an increasing number of these diseases, and this trend will become more pronounced as chemotherapy develops. The results achieved with available chemicals and present dosage schedules are impressive.
Book Synopsis Trees and Hierarchical Structures by : Andreas Dress
Download or read book Trees and Hierarchical Structures written by Andreas Dress and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "raison d'etre" of hierarchical dustering theory stems from one basic phe nomenon: This is the notorious non-transitivity of similarity relations. In spite of the fact that very often two objects may be quite similar to a third without being that similar to each other, one still wants to dassify objects according to their similarity. This should be achieved by grouping them into a hierarchy of non-overlapping dusters such that any two objects in ~ne duster appear to be more related to each other than they are to objects outside this duster. In everyday life, as well as in essentially every field of scientific investigation, there is an urge to reduce complexity by recognizing and establishing reasonable das sification schemes. Unfortunately, this is counterbalanced by the experience of seemingly unavoidable deadlocks caused by the existence of sequences of objects, each comparatively similar to the next, but the last rather different from the first.

This book was released on 2013-03-09 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: In August 1988. the Sixth International Coral Reef Symposium was held in Townsville resulting in an influx of most of the world's coral reef sCientists to the city. We seized this opportunity at the Australian Institute of Marine Science to run a small workshop immediately before the symposium on the outbreaks of the crown-of-thorns starfish. Aeanthaster planei. We invited that small band of mathematicians who had been modelling the phenomenon, (and who may not have normally attended an international meeting so thoroughly dedicated to natural science) to meet with those SCientists who had been been actively working on the phenomenon in the field. John Casti notes in his delightful new book Alternate Realities (Wiley, 1989): 'If the natural role of the experimenter is to generate new observables by which we know the processes of Nature, and the natural role of the mathematician is to generate new formal structures by which we can represent these processes. then the system SCientist finds his niche by serving as a broker between the two. ' I think our book shows the fruits of that brokerage through the wide range of models explored within its pages. the high level of collaboration and interaction across disciplines evident in the individual papers, and in the emerging synthesis that reflects a far deeper understanding of this complex phenomenon than was possible even a few years ago.
