This volume of Progress in Inflammation Research is a unique
compilation of work performed by a wide spectrum of investigators
from different medical disciplines. It is fascinating that dietary
alterations of fatty acid intake can result in a range of salutory
changes in a great variety of medical conditions. Most of the good
scien tific work which has led to these observations has been
performed over just the last two decades. This is of course not a
very long time in the context of the history of the human species.
Recently performed analysis of fat intake from paleolithic times
has indicated that our hunter-gatherer ancestors consumed as much
cholesterol as modern Western man, but strikingly less saturated
fatty acid and more polyunsatu rates, including n-3 fatty acids.
Wild game has the terrestrial source of n-3 incorpo rated in its
fat since browsing animals derive 18:3n-3 (alpha-linolenic acid)
natural ly from leafy plants. There is, however, little opportunity
for modern Western man to get n-3 fatty acids from the diet if one
does not consume fish. Modern agribusiness provides ani mal feeds
high in n-6 fatty acids, mostly derived from linoleic acid
(18:2n-6) in corn feed. Therefore, grazing animals have no access
to alternative fatty acids in either feed or grasses, the latter
containing little or none of these potentially beneficial highly
polyunsaturated fatty acids."
Hands-on researchers describe in step-by-step detail 73 proven
laboratory methods and bioinformatics tools essential for analysis
of the proteome. These cutting-edge techniques address such
important tasks as sample preparation, 2D-PAGE, gel staining, mass
spectrometry, and post-translational modification. There are also
readily reproducible methods for protein expression profiling,
identifying protein-protein interactions, and protein chip
technology, as well as a range of newly developed methodologies for
determining the structure and function of a protein. The
bioinformatics tools include those for analyzing 2D-GEL patterns,
protein modeling, and protein identification. All laboratory-based
protocols follow the successful Methods in Molecular Biology (TM)
series format, each offering step-by-step laboratory instructions,
an introduction outlining the principle behind the technique, lists
of the necessary equipment and reagents, and tips on
troubleshooting and avoiding known pitfalls.

Examining the chemical modification of biological polymers and
the emerging applications of this technology, Chemical Modification
of Biological Polymers reflects the change in emphasis in this
subsection of biotechnology from the study of protein structure and
function toward applications in therapeutics and diagnostics.
Highlights
- The basic organic chemistry of the modification proteins,
nucleic acids, oligosaccharides, polysaccharides, and their
applications
- New analytical technologies used to characterize the chemical
modification of biological polymers
- Identification of in vivo, non-enzymatic chemical modification
of biological polymers
- Specific chemical modifications to generate biopharmaceutical
products
This book covers the basics on the organic chemistry underlying
the chemical modification of biopolymers, including updates on the
use of various chemical reagents. It describes the current status
of chemical modification of biological polymers and emerging
applications of this technology in biotechnology. These
technologies are important for the manufacture of conjugate
proteins used in drug delivery, for the preparation of nucleic acid
microarrays, and for the preparation of hydrogels and other
materials used in tissue engineering.
Authoritative investigators active in the discovery, development,
and application of biological anti-infective agents concisely
review their use and potential in preventing and treating human
disease. Focusing on biotherapeutic entities that have been tested
in controlled studies, the prominent experts illuminate the
scientific underpinnings of their therapeutic power, assess their
possible risks in the treatment of infectious diseases, and outline
the research needed to better define their effectiveness. In
addition, they also consider how biotherapeutic agents may be
genetically engineered for maximum intestinal and vaginal
production of bioactive substances in vivo. Biotherapeutic Agents
and Infectious Diseases brings together all the evidence needed to
understand and capitalize on the considerable promise of this
significant new class of biotherapeutic entities.

F. Macfarlane Burnet I have been an interested onlooker for many
years at research on the biology of trace elements, particularly in
its bearing on the pas toral and agricultural importance of copper,
zinc, cobalt, and mo lybdenum deficiencies in the soil of various
parts of Australia. More recently I have developed a rather more
specific interest in the role of zinc, particularly in relation to
the dominance of zinc metalloenzymes in the processes of DNA
replication and repair, and its possible significance for human
pathology. One area of special significance is the striking effect
of zinc deficiency in the mother in producing congenital
abnormalities in the fetus. The fact that several chapters in the
present work are concerned with this and other aspects of zinc
deficiency is, I fancy, the editors jus tification for inviting me
to write this foreword. In reading several of the chpaters before
publication, my main impression was of the great potential
importance of the topic of trace metal biology in both its negative
and positive aspects-the effects of deficiency of essential
elements and the toxicity of such pollutants of the modern world as
lead or mercury mainly as or ganic compounds."
Cancer has become the most critical health problem in the United
States. It is expected that 25% of the people will develop this
dread disease, and many of these will die from the malady. The
causes of cancer are varied, but the best estimate available is
that 70--90% arise from environmental factors. These statistics
have triggered widespread governmental action along two lines: (l)
An effort to identify those chemicals and conditions that give rise
to malignant processes has been mounted by the Carcino genesis
Testing Program, the National Cancer Program, and subse quently,
the National Toxicology Program. (2) Regulatory laws have been
enacted that are administered by agencies such as TSCA, FIFRA, EPA,
FDA, OSHA, and so on, whose mission is to minimize public ex posure
to carcinogens. Since direct verification that specific chemicals
induce cancer in hu of unanticipated expo mans is necessarily
limited to known incidences sure and is therefore rare, most
chemicals are identified as carcinogens only by laboratory
experiments. At present, the only accepted procedure is long-term
animal bioassay, and not only are these studies expensive and
time-consuming, but current worldwide resources permit the evalua
tion of only 300-400 chemicals per year, a miniscule amount
compared to what is available in the commercial world: 30,000
existing chemicals, with approximately 700 new such materials being
introduced every year."
Conceived at a time when biological research on aggression and
violence was drawn into controversy because of sociopolitical
questions about its study, this volume provides an up-to-date
account of recent biological studies performed -- mostly on humans.
A group of scientists recognized the importance of freedom of
inquiry and deemed it vital to address the most promising
biological research in the field. The focus on biological
mechanisms is not meant to imply that biological variables are
paramount as a determinant of violence. Rather, biological
variables operate in conjunction with other variables contributing
to aggression or violence, and a complete understanding of this
phenomenon requires consideration of all influences bearing on it.
This book will familiarize readers with the rapidly growing and
increasingly significant body of knowledge on the biological bases
of human antisocial, aggressive, and violent behaviors. The editors
concentrated on biological influences that support the basic
physiological and biochemical processes of the brain and did not
cover those biological influences that impact on the health of the
individual such as head injury, pregnancy and birth complications,
diet, and exposure to lead and other toxins. They focused on
biological influences to illuminate their role in the complex
behavioral phenomenon of violence.
Three different approaches to the biological study of human
antisocial, aggressive, and violent behaviors are represented --
genetic, neurobiological, and biosocial. Representing each of these
three approaches, individual chapters from investigators in
psychobiology, biological psychiatry, and basic-clinical
neurosciences address the most recent experimental findings,
methods, theory, and common misconceptions in the biological study
of aggression and violence. The areas of primary focus are behavior
and molecular genetics, neurochemistry and hormones, neuroimaging,
psychophysiology and developmental psychobiology. Generally
speaking, investigators following these different approaches have
experience in different scientific backgrounds, select different
methods, generate different analyses, employ different conceptual
definitions for some of the same terms, and assume a different
philosophical stance in attempting to explain violence.
Nevertheless, all are united in their efforts to understand the
biological underpinnings of violence. This book then assumes a
comprehensive approach wherein different levels of analysis and
different approaches inform each other. It is clear from the
studies reported that aggression and violence are multidetermined
phenomena and understanding them requires an interdisciplinary
approach spanning economic, sociopolitical, psychological,
sociological, and criminological as well as biomedical
considerations. Nature (biology) and nurture (experience, context)
are fundamentally inseparable in explaining aggression and
violence; biology may affect experience or context, but experience
or context also influences biology. Both need to be studied in a
search for explanations of this phenomena.
Over the last 20 years, biochemistry and molecular biology have
undergone a revolution that has affected our understanding of the
oral cavity. Topics in Dental Biochemistry is primarily designed
for students of dentistry who need to relate biochemistry and
molecular biology to dentally related topics in physiology,
nutrition, anatomy, histology, microbiology, and immunology. The
book will also be of value for dental professionals, scientists,
and practitioners of medicine who are interested in hard and soft
tissue structure and disease. It provides the necessary basic
scientific background for a clearer understanding of bone, tooth,
saliva, and surrounding soft tissue research and also for an
appreciation of how dental caries and periodontal disease might be
better diagnosed and controlled in the future. Dentistry was
developed to treat dental caries, but since the early 20th century
it has increasingly been treating periodontal, traumatic and
genetic diseases affecting tooth structure and attachment.
Fluoridation is discussed at length. Other methods for controlling
dental caries and new or suggested methods for controlling oral
hygiene and periodontal disease are also discussed.
Parasitic zoonoses, the parasitic diseases transmitted between
humans and other vertebrate animals, are widespread. The increasing
pace of internationalization changes in diet and easy movement from
one part of the world to another has caused parasitic zoonoses to
be more prevalent. Consequently, these diseases have become the
focus of recent research by parasitologists and pathologists whose
work is presented in this book. Included in addition to the
pathology of parasitic zoonoses and recent trends in research of
imported parasites are the classification of phenotypes of anisakid
nematodes, the immunohistopathological diagnostic method, and
molecular technology to detect and diagnose parasites. Also
included are papers on parasitology and international health and
the pathology of cerebral malaria. With 38 color illustrations,
this book is an invaluable resource for parasitologists,
pathologists, and clinicians.
This work is concerned with a group of proteins which were
originally consid ered to be an esoteric phenomenon but which have
now been shown to play critical roles both in normal and stressed
cells as well as being involved in a variety of human diseases. It
is the purpose of this work to give a comprehen sive view of these
proteins and their various aspects. After an introductory chapter
providing an overview of these proteins, the work is divided into
four main sections each of which deals with one important aspect of
these proteins. Thus, the first section contains a series of
chapters which describe individual stress proteins and their roles
in particular biological phenomena. Evidently, the induction of
these proteins by elevated tempera ture or other stresses is their
defining feature and the second section of this book therefore
considers the regulation of stress protein gene expression both by
stressful stimuli such as elevated temperature or ischaemia and by
non stressful stimuli such as cytokines.
From the young mining town of Johannesburg came ideas of peaceful
struggle which spread across the world. Formulated by Mohandas
Gandhi in the early 1900s, the philosophy of Satyagraha (soul force
or passive resistance) became an inspiration to millions all over
the world. For a decade, during the formative years of his
philosophy, Gandhi lived in and around Johannesburg where he
established a prosperous law practice, though his legal work was
soon overtaken by his political activism in support of Indian
rights. During that decade, he made the streets and suburbs of the
city his own, changing homes frequently and walking tirelessly.
Tolstoy Farm and other places and buildings captured in words and
pictures in this evocative book are landmarks of Ghandi’s
personal and political growth. The sites featured span huge social
divides, from slums and shanties of the old Indian Location to the
comfortable suburbs reserved for whites. Considered as a whole,
they and the events surrounding them are an essential part of the
Gandhian experience.
It should not come as too much of a surprise that biological
membranes are considerably more complex than lipid bilayers. This
has been made quite clear by the fluid-mosaic model which considers
the cell membrane as a two-dimensional solution of a mosaic of
integral membrane proteins and glycoproteins firmly embedded in a
fluid lipid bilayer matrix. Such a model has several virtues, chief
among which is that it allows membrane components to diffuse in the
plane of the membrane and orient asymmetrically across the
membrane. The model is also remarkable since it provokes the right
sort of questions. Two such examples are: Does membrane fluidity
influence enzyme activity? Does cholesterol regulate fluidity?
However, it does not go far enough. As it turns out, there is now
another version of this model, the so-called post-fluid mosaic
model which incorporates two concepts, namely the existence in the
membrane of discrete domains in which specific lipid-lipid,
lipid-protein and protein-protein interactions occur and ordered
regions that are in motion but remain separate from less ordered
regions. We must admit that both are intriguing problems and of
importance in guiding our thinking as to what the next model might
be.
We have chosen not to include the subject of membrane transport in
the present volume. This obviously represents a break with
convention. However, the intention is to have the topic covered
subsequent volumes relating to organ systems. It would be right to
regard this as an attempt to strengthen the integrated approach to
the teaching of medicine.
This book discusses properties of apoptosis and other cell death
modalities in cancer pathogenesis and treatment. Its nine chapters
discuss modulation of anti-tumor inflammatory and immune responses,
effects on the tumor microenvironment, to strategies for improving
pro-apoptotic therapies, mechanisms and implications for disease
pathogenesis, axl and mer receptor tyrosine kinases, immunogenic
apoptotic cell death and anti-cancer immunity and cancer cell
death-inducing radiotherapy. This book places the onco-biology of
apoptosis in clear and objective perspective through an expertly
synthesized series of reviews. Apoptosis in Cancer Pathogenesis and
Anti-cancer Therapy is a deft and thorough exploration of
cutting-edge research in apoptosis and anti-cancer mechanisms from
basic biology to oncology. It highlights a rapidly growing field
within cancer research and is essential reading for oncologists,
biochemists and advanced graduate students alike.
