Biophysics of Photoreceptors and Photomovements in Microorganisms (Nato Science Series A: #211)

by F. Lenci Francesco Ghetti Giuliano Colombetti D. P. Häder Pill-Soon Song

This volume contains the lectures given at the NATO Advanced Study Institute on "Biophysics of Photoreceptors and Photomovements in Microorganisms" held in Tir­ renia (Pisa), Italy, in September 1990. The Institute was sponsored and mainly funded by the Scientific Affairs Division of NATO; the Physical Science Committee and the Institute of Biophysics of National Research Council of Italy also supported the School and substantially contributed to its success. It is our pleasant duty to thank these institu­ tions. Scientists from very different backgrounds contributed to the understanding of this fast developing field of research, which has seen considerable progress during the last years. The areas of expertise ranged from behavioral sciences, supported by sophi­ sticated techniques such as image analysis or laser light scattering, to spectroscopy, ap­ plied, in different time domains, to the study of the primary photoreactions, to electro­ physiology, biochemistry or molecular biology, with the aim of analyzing the various steps of the transduction chains and how they control the motor apparatus of the cells. The organisms studied covered a wide range, from bacteria to algae, fungi and other eukaryotes. Thus, the ASI represented a successful opportunity for carrying on and imple­ menting an interdisciplinary approach to the study of the biophysical basis of photore­ ception and photosensory transduction in aneural organisms, with special attention to the basic phenomena and the underlying molecular events. We hope that this book has caught the spirit in which the ASI was conceived.

The Biophysics of Photosynthesis (Biophysics for the Life Sciences #11)

by John Golbeck Art Est

The volume is intended as an introduction to the physical principles governing the main processes that occur in photosynthesis, with emphasis on the light reactions and electron transport chain. A unique feature of the photosynthetic apparatus is the fact that the molecular structures are known in detail for essentially all of its major components. The availability of this data has allowed their functions to be probed at a very fundamental level to discover the design principles that have guided evolution. Other volumes on photosynthesis have tended to focus on single components or on a specific set of biophysical techniques, and the authors’ goal is to provide new researchers with an introduction to the overall field of photosynthesis.The book is divided into sections, each dealing with one of the main physical processes in photosynthetic energy conversion. Each section has several chapters each describing the role that a basic physical property, such as charge or spin, plays in governing the process being discussed. The chapters proceed in an orderly fashion from a quantum mechanical description of early processes on an ultrafast timescale to a classical treatment of electron transfer and catalysis on a biochemical timescale culminating in evolutionary principles on a geological timescale.

Biophysics of the Failing Heart: Physics and Biology of Heart Muscle (Biological and Medical Physics, Biomedical Engineering)

by R. John Solaro and Jil C. Tardiff

Subjects in the monograph “Biophysics of the Failing Heart” include state of the art chapters considering major biophysical mechanisms for why hearts responding to acquired or inherited stressors enter into maladaptive processes eventually leading to an inability of the heart to respond efficiently to hemodynamic loads especially during exercise. The chapters describe biophysical techniques that have been applied to determine the triggers for the heart failure process as well as the mechanisms for sustaining the disorders. These techniques include measurements of active and passive mechanical properties and hemodynamics at levels of organization ranging from molecules to hearts beating in situ. Biophysical concepts and approaches are also applied to determination of signaling and signal transduction, energetics, ionic currents, transport processes, electro-chemical and chemo-mechanical coupling. By its emphasis on biophysical aspects of a prevalent clinical condition, the monograph is unique in its perspective and focus. The breadth of information in the chapters all in one place will be of value to clinicians and researchers at all levels. Modern research approaches and clinical understanding of heart failure demands integration of multiple aspects of the disorders. In most cases, combinations of clinician scientists and researchers author the chapters. A main benefit of the book is couched in its didactic approach together with its emphasis on how biophysical concepts and techniques aid in diagnosis and development of new therapies.

Biophysics of the Pancreatic β-Cell (Advances in Experimental Medicine and Biology #211)

by Illani Atwater Eduardo Rojas Bernat Soria

Pancreatic a-cell biophysics has undergone a veritable informa­ tion explosion in the past two years. Single channel and macroscopic currents have become easily accessible following the introduction of the patch clamp technique. In addition to this new approach, further development of techniques for optical measurements, ion-sensitive microelectrodes, permeabilized cells and mathematical modelling have recently added to the now classical techniques of membrane potential recording and tracer flux measurement. The International Workshop on Biophysics of the Pancreatic a-Cell held in Alicante (Spain) on Sep­ tember 30 - October 1, 1985, has now given us the opportunity to share experiences with these new techniques applied to the a-cell. Further­ more this was the first occasion for most of the groups doing patch­ clamp studies of the a-cell to decide on appropriate nomenclature and to debate the different characteristics of the a-cell ionic channels. To make this information available to the larger scientific community a record of the meeting has been assembled in this book. It is a collection of research papers by leading scientists at the meet­ ing working on biophysical, biochemical and physiological aspects. of secretion. We grouped their contributions in seven sections, includ­ ing new experimental approaches, K-channels, Ca-channels, role of ionic channels, intracellular ionized calcium, neural regulation and mechanisms of insulin release. Each section gives an account of the state of the problem at the time of the meeting, and the subjects are analyzed from the different perspectives of the various contributors.

Biopoetics: Towards an Existential Ecology (Biosemiotics #14)

by Andreas Weber

Meaning, feeling and expression – the experience of inwardness – matter most in human existence. The perspective of biopoetics shows that this experience is shared by all organisms. Being alive means to exist through relations that have existential concern, and to express these dimensions through the body and its gestures. All life takes place within one poetic space which is shared between all beings and which is accessible through subjective sensual experience. We take part in this through our empirical subjectivity, which arises from the experiences and needs of living beings, and which makes them open to access and sharing in a poetic objectivity. Biopoetics breaks free from the causal-mechanic paradigm which made biology unable to account for mind and meaning. Biology becomes a science of expression, connection and subjectivity which can understand all organisms including humans as feeling agents in a shared ecology of meaningful relations, embedded in a symbolical and material metabolism of the biosphere.

Biopreparedness and Public Health: Exploring Synergies (NATO Science for Peace and Security Series A: Chemistry and Biology)

by Iris Hunger Vladan Radosavljevic Goran Belojevic Lisa D. Rotz

The terrorist use of diseases as bioweapons has been one of the major security concerns in recent years, particularly after the anthrax letter attacks in the USA in 2001. This uncertain threat of intentional outbreaks of diseases exists side by side with the constantly changing very real threat from diseases, epidemics and pandemics as recently illustrated by the H1N1 influenza pandemic, SARS, and H5N1 bird influenza events. This publication contains case studies on the public health planning for (un)usual disease outbreaks for 11 large and small countries with a focus on South Eastern Europe. In many countries, military entities traditionally play an important role in emergency response to disease outbreaks. In smaller countries, very little exists, however, in terms of specific biopreparedness efforts (in both the military and civilian area), which is at least partly due to a relatively low bioterrorism threat perception, and serious resource constraints. The uncertainty associated with the bioterrorism threat makes public health preparedness planning for such events politically and financially very difficult. The similarity of responding to bioterrorism events and natural disease outbreaks from a public health point of view suggests the merit of looking at biopreparedness as a part of overall health emergency planning, not as a separate effort.
