This unique book provides an accessible introduction to both the
scientific background and the key people involved in the discovery
and use of radiation and radioactivity. It begins by providing a
short history of radiation exposures and radiation poisoning; from
the early inappropriate use of X-rays and radium cures through the
misadventures of the Manhattan Project and the Chernobyl disaster,
to the high-profile and deliberate poisoning of Alexander
Litvinenko in London with polonium-210, which gave rise to
worldwide media attention. The chapters provide a catalogue of
deliberate criminal acts, unfortunate accidents, and inadvertent
radiation exposures, exploring well-known events in detail, as well
as some not so well-known occurrences. It works through the topics
by focusing on human stories and events and their biological
impact. In addition, it covers descriptions of the beneficial uses
of radiation and radioactivity. This book can be enjoyed by any
reader with a general interest in science, as well as by students
and professionals within the scientific and medical communities.
Key features Authored by a subject area specialist who has worked
in both clinical practice and academia and was involved with the
national media following incidents of national and international
importance Provides a unique human perspective into well-known and
some lesser known events and a concise history of the discovery of
radiation and the events that followed Adds scientific and medical
background to a subject of high media interest
What are the relations between the shape of a system of cities and
that of fish school? Which events should happen in a cell in order
that it participates to one of the finger of our hands? How to
interpret the shape of a sand dune? This collective book written
for the non-specialist addresses these questions and more
generally, the fundamental issue of the emergence of forms and
patterns in physical and living systems. It is a single book
gathering the different aspects of morphogenesis and approaches
developed in different disciplines on shape and pattern formation.
Relying on the seminal works of D'Arcy Thompson, Alan Turing and
Rene Thom, it confronts major examples like plant growth and shape,
intra-cellular organization, evolution of living forms or motifs
generated by crystals. A book essential to understand universal
principles at work in the shapes and patterns surrounding us but
also to avoid spurious analogies.
This book focuses on the study of how the properties of nanodiscs,
such as lipid composition and size, influence the function of the
embedding integral membrane protein, bacteriorhodopsin. The author
performed systematic studies to show that the lipid composition and
the charge of the hydrophobic head and the structure of hydrophilic
tails affect the photocycle pathway of bacteriorhodopsin, which is
closely associated with its proton-pumping activity. Furthermore,
the author demonstrated a highly efficient method for extracting
membrane proteins directly from the biological membrane, preserving
protein conformation, function and essential native lipids. This
book demonstrates optimization and sample preparation, and presents
practical methods of preparing membrane protein-embedded nanodisc
samples for biophysical studies, which benefit structural and
functional studies in the field of membrane protein
characterization, both.
This book is dedicated to label-free, non-invasive monitoring of
cell-based assays and it comprises the most widely applied
techniques. Each approach is described and critically evaluated by
an expert in the field such that researchers get an overview on
what is possible and where the limitations are. The book provides
the theoretical basis for each technique as well as the most
successful and exciting applications. Label-free bioanalytical
techniques have been known for a long time as valuable tools to
monitor adsorption processes at the solid-liquid interface in
general - and biomolecular interaction analysis (BIA) in
particular. The underlying concepts have been progressively
transferred to the analysis of cell-based assays. The strength of
these approaches is implicitly given with the name 'label-free':
the readout is independent of any label, reagent or additive that
contaminates the system under study and potentially affects its
properties. Thus, label-free techniques provide an unbiased
analytical perspective in the sense that the sample is not
manipulated by additives but pure. They are commonly based on
physical principles and read changes in integral physical
properties of the sample like refractive index, conductivity,
capacitance or elastic modulus to mention just a few. Even though
it is not implied in the name, label-free approaches usually
monitor the cells under study non-invasively meaning that the
amplitude of the signal (e.g. electric field strength, mechanical
elongation) that is used for the measurement is too low to
interfere or affect. In contrast to label-based analytical
techniques that are commonly restricted to a single reading at a
predefined time point, label-free approaches allow for a continuous
observation so that the dynamics of the biological system or
reaction become accessible.
More profound understanding of the nature of light and
light-matter interactions in biology has enabled many applications
in the biology and medical fields. So a new discipline is born,
namely biophotonics.
The aim of this book is to review the current state-of-the-art
of the field by means of authoritative chapters written by the
world leaders of the respective fields. This book will be useful
not only to professionals, but also to graduate students interested
in this field.

Due to recent advancements in the development of numerical
algorithms and computational hardware, computer simulations of
biological membranes, often requiring use of substantial
computational resources, are now reaching a mature stage. Since
molecular processes in membranes occur on a multitude of spatial
and time scales, molecular simulations of membranes can also serve
as a testing ground for use of multi-scale simulation techniques.

computer science, theoretical physics. This Second Edition provides
a solid introduction to the techniques of statistical mechanics for
graduate students and researchers in computational biology and
biophysics. Material has been reorganized to clarify equilbrium and
nonequilibrium aspects of biomolecular systems Content has been
expanded, in particular in the treatment of the electrostatic
interactions of biomolecules and the application of non-equilibrium
statistical mechanics to biomolecules New network-based approaches
for the study of proteins are presented. All treated topics are put
firmly in the context of the current research literature, allowing
the reader to easily follow an individual path into a specific
research field. Exercises and Tasks accompany the presentations of
the topics with the intention of enabling the readers to test their

Quantum physics provides the concepts and their mathematical
formalization that lend themselves to describe important properties
of biological networks topology, such as vulnerability to external
stress and their dynamic response to changing physiological
conditions. A theory of networks enhanced with mathematical
concepts and tools of quantum physics opens a new area of
biological physics, the one of systems biological physics.
This book encompasses the full breadth of the super-resolution
imaging field, representing modern techniques that exceed the
traditional diffraction limit, thereby opening up new applications
in biomedicine. It shows readers how to use the new tools to
increase resolution in sub-nanometer-scale images of living cells
and tissue, which leads to new information about molecules,
pathways and dynamics. The book highlights the advantages and
disadvantages of the techniques, and gives state-of-the-art
examples of applications using microscopes currently available on
the market. It covers key techniques such as stimulated emission
depletion (STED), structured illumination microscopy (SSIM),
photoactivated localization microscopy (PALM), and stochastic
optical reconstruction microscopy (STORM). It will be a useful
reference for biomedical researchers who want to work with
super-resolution imaging, learn the proper technique for their
application, and simultaneously obtain a solid footing in other
techniques.

This volume contains the Proceedings of the NATO Advanced Research
Workshop (ARW) and Emil-Warburg-Symposium (EWS) "Nonlinear Coherent
Structures in Phy sics and Biology" held at the University of
Bayreuth from June 1 -4, 1993. Director of the ARW was K. H.
Spatschek, while F.G. Mertens acted as the co-director, host, and
organizer of the EWS. The other members of the scientific
organizing committee were A.R. Bishop (Los Alamos), J.C. Eilbeck
(Edinburgh), and M. Remoissenet (Dijon). This was the eighth
meeting in a series of interdisciplinary workshops founded by our
French colleagues who had organized all the previous workshops,
e.g. 1989 in Montpel lier and 1991 in Dijon. We were asked to
organize the meeting this time in Germany. Of course, we wanted to
keep the character defined by the previous meetings, which were
always characterized by an open and friendly atmosphere, being not
too large in quantity, but high in quality. This time altogether
103 participants attended the workshop. During the past years most
of the participants met several times and discussed problems
connected with the generation of nonlinear coherent structures in
physics and biology."
The Geometric Induction of Bone Formation describes new biomimetic
biomaterials that offer mechanistic osteogenic surfaces for the
autonomous and spontaneous induction of bone formation without the
addition of osteogenic soluble molecular signals of the
transforming growth factor- supergene family. The chapters frame
our understanding of regenerative medicine in primate species,
including humans. The goal is to unravel the fundamental biological
mechanisms of bone formation unique to non-human and human
primates. The broad target audience dovetails with several
disciplines both in the academic and private biotech sectors
primarily involved in molecular biology, tissue biology, tissue
engineering, biomaterial science, and reconstructive, orthopedic,
plastic, and dental surgery. Key Features Includes outstanding
images of undecalcified whole mounted sections Summarizes non-human
primate research - ideal for clinical translation Reviews methods
for creating devices capable of making bone autonomously, i.e. an
intrinsically osteo-inductive bioreactor and/or biomaterial

whole spectrum of tissue biology, from basic molecular biology to
clear-cut morphology and pre-clinical application in non-human
primate species Intended for audiences in both academic research
and the biotech industry
While the effects of pressure change are readily quantified in
physics, chemistry, and engineering applications, the physiology,
medicine, and biology of pressure changes in living systems are
much more complicated. This complex science translated to technical
diving is discussed in a five-part series, with each topic
self-contained and strategically developed in relationship to
diving, spanning many disciplines and focusing on a number of
technical areas. A suite of application exercises is provided at
strategic points in the text. Additional material focusing on
diving data, statistical correlations, underwater tests, and risk
is included.
This book is rather unique in its approach and coverage. The
approach is essentially that of an engineering textbook,
emphasizing the quantitative aspects and highlighting the
fundamentals and basic concepts involved. The coverage progresses
in a logical and systematic manner from the subcellular, starting
with the electrophysiology of the cell membrane, then proceeding to
synapses, neurons, and muscle, before considering neuronal motor
ensembles and the neuromuscular system as a whole. Simple, clear,
and comprehensive explanations are given throughout. After an
introductory chapter on some background material in biology,
biophysics, and chemical kinetics, a substantial part of the book
(Chapters 2-8) necessarily covers in considerable detail the basic
components and processes that underlie the electrical and
associated activities of the nervous system. The remaining chapters
of the book (Chapters 9-13) focus on the neuromuscular system,
starting with the structure of muscle cells, the generation of
force by muscular contraction, and muscle receptors. The last
chapter examines aspects of the control of movement, motor learning
and memory, the maintenance of posture, and locomotion, and
critically examines some of the theories that have been advanced to
explain how movement is controlled. The book is intended for
undergraduate or graduate students in the natural sciences,
mathematics, or engineering who seek a deeper understanding of the
fundamentals of neuroscience and the somatomotor system, in
accordance with the aforementioned objectives. The book can serve
as a textbook for a one-semester course on the neuromuscular system
or as a reference in a more general course on neuroscience.
Provides a thorough analytical treatment of membrane
electrophysiology, starting from the first principles Emphasizes
strongly the basic and fundamental concepts throughout Discusses
thoroughly the essential features and properties of the basic
constituents of the nervous system, that is, neurons and synapses,
