The study of coelenterates is now one of the most active fields of
invertebrate zoology. There are many reasons for this, and not
everyone would agree on them, but certain facts stand out fairly
clearly. One of them is that many of the people who study
coelenterates do so simply because they are interested in the
animals for their own sake. This, however, would be true for other
invertebrate groups and cannot by itself explain the current boom
in coelenterate work. The main reasons for all this activity seem
to lie in the considerable concentration of research effort and
funding into three broad, general areas of biology: marine ecology,
cellular-developmental biology and neurobiology, in all of which
coelenterates have a key role to play. They are the dominant
organisms, or are involved in an important way, in a variety of
marine habitats, of which coral reefs are only one, and this
automatically ensures their claims on the attention of ecologists
and marine scientists. Secondly, the convenience of hydra and some
other hydroids as experimental animals has long made them a natural
choice for a variety of studies on growth, nutrition, symbiosis,
morphogenesis and sundry aspects of cell biology. Finally, the
phylogenetic position of the coelenterates as the lowest metazoans
having a nervous system makes them uniquely interesting to those
neurobiologists and behaviorists who hope to gain insights into the
functioning of higher nervous systems by working up from the lowest
level.
Parasites evolve under selective pressures which are different from
those acting on free-living organisms. The aim of this textbook is
to present these pressures and to show how they have shaped the
ecology of parasites over evolutionary time. Broad theoretical
concepts are explained simply and clearly and illustrated
throughout with example organisms. The book will be an invaluable
text for advanced undergraduate biologists who are studying
evolutionary biology, ecology, population biology, parasitology and
evoluationary ecology. It will also prove to be a valuable
reference to postgraduate students and researchers in the same
fields.
Recently there have been many advances in the understanding of the
genetic basis of development and regular breakthroughs are being
made in the field of tumour cell targeting. Both these areas of
research are coming together in terms of their perception of
programmed cell death. A broad introduction of the biological
significance of cell death is followed by a major review of the
significance of physiological cell death in tumours and the factors
that influence it. The volume includes a consideration of the role
and functions of lymphokines and their bearing on tumour cell
targeting and cell killing. The interleukins, interferons and
tumour necrotic factor (TNF) are presented in terms of their
functional significance rather than in a sequential or systematic
manner. This volume concentrates on the bases of biological or
programmed cell death. Aspects of necrosis are, however, of
necessity covered in comparative and technical terms. The central
section on cell death in tumours is followed by a resume of the
techniques employed in demonstrating cell death and this section
closes with an appendix giving practical details of selected
methods. It is hoped that the book may help potential research
workers focus not only on the underlying molecular biology of
programmed cell death but also provide impetus for the development
of appropriate therapeutic regimes in tumour research.
An identification handbook containing descriptions of 974 species
of non-gilled fungi in 277 genera and figures of 543 of them. There
are two major keys to genera and a key to the species in each genus
that contains more than one species. The fungi described and
illustrated can nearly all be found in Great Britain. The book aims
to stimulate interest in groups of fungi which have hitherto
attracted relatively few workers. Resupinate fungi, club fungi,
jelly fungi, brackets, earth stars, puffballs and so on are not
difficult to identify with a little practice and many of them
flourish and sporulate freely during the winter months and thus it
is possible to study mycology all year round if all groups are
studied. In this book measurements, except where otherwise stated,
are in thousandths of a millimetre. Terms which may be unfamiliar
are explained in the glossary and for quick reference genera in the
two main sections are arranged in alphabetical order.
W. French Anderson, M.D. The publication of this book comes at an
opportune time for the young field of human gene therapy. After a
decade of long struggle at the laboratory bench and many long hours
under the harsh lights of the federal review process, gene therapy
has emerged as a legitimate scientific discipline. It is now time
to move away from the period of questioning whether gene therapy
will be a useful part of the physician armamentarium to begin to
actively teach the concepts and practices that make gene therapy a
reality. This book is a comprehensive collection of chapters that
describe the basic biology and potential application of viruses as
gene transfer reagents. It is not a coincidence that a modified
virus was the reagent used in the first human gene therapy trials.
Viruses have evolved with the human species (and most likely with
all forms of life) to be the masters of gene transfer.
Initially believed to be inactive molecules, glycans are now
considered essential for life, both under normal and pathological
conditions.
This volume of the series "Biology of Extracellular Matrix "
reviews the most recent findings on the role of glycans in the
development of diseases and the possible therapeutic use of this
class of molecules. It shows how the interaction of glycans with
growth factors, growth factor binding proteins, extracellular
proteases, protease inhibitors, chemokines, morphogens, and
adhesive proteins regulates inflammation, infection, cancer,
atherosclerosis, thrombosis and embryonic stem cell biology.
Furthermore, an extensive survey about the structure and
pharmacological effects of unique marine glycosaminoglycans is
discussed as well as the possibility of using these glycans as
therapeutic agents.
Helminths include one of the most diverse and geographically
widespread groups of parasites which infect humans and animals.
About 100 species have been reported from humans, usually producing
asymptomatic infection or mild symptoms. However, about 20 species
are of public health importance causing severe or even fatal
infections. In many parts of Africa parasitic helminths are
responsible for enormous economic losses, hampering rural
development programmes and reducing the pace of economic growth.
Many parasitic helminths are either zoonoses (diseases naturally
transmitted between vertebrate animals and man) or have evolved
from animal parasites. The modification of the environment through
wars, famine and the ever expanding and increasingly mobile human
population brings people into close contact with new environments
and wildlife species which makes the study and control of zoonoses
of special interest and complexity. In Africa, the transmission of
helminth parasites is highly influenced by the ever changing social
and cultural differences between diverse groups of peoples and
their interaction with wild and domestic animals. It is not
surprising, therefore, that approaches to the study and control of
parasitic zoonoses require intersectoral cooperation between
physicians, veterinarians, parasitologists, zoologists,
demographers, anthropologists, engineers and economists to provide
the breadth of knowledge and expertise required to develop our
understanding of these diseases and to devise methods for their
control. This book provides a selective compilation of parasitic
helminths, many of which are zoonoses which create important
economic and public health problems in Africa.
The system of the multicellular animals presented here is an alternative to the traditional classification which still operates with the categories of Carl v. Linné, including typological divisions in artificial species groups. In a new approach to the phylogenetic order in nature this book strives for an objective systematisation of the Metazoa. It seeks a new path in the field of research and academic teaching based on the theory and methodology of phylogenetic systematics. This third volume covers the Metazoa from the Nemathelminthes to the Mammalia.
Applications of nanoparticles to the human life and tools in
diagnosis and therapy in field of clinical medicine holds
importance and has been an prime focus of biomedical and clinical
research for quite sometime, though their application in veterinary
medicine is a relatively new focus area of research. Prior to human
applications, studies are initially conducted on animals models.
Thus toxicity based studies and study of impact of nanoparticles on
animal immune system finds importance. In the second volume of the
book we discuss the immune system in animals across invertebrates
and vertebrate phylas and discuss the impact of nanoparticles in
animals life, health, survival and immune system. The book
highlights the toxic effects of nanoparticles as environmental
pollutants and their adverse impact on animal life forms. Both
volumes are also included in a set ISBN 978-3-11-065666-4.
Nearly thirty million species of organisms are believed to now live
on Earth. In addition to accumulating evidence from classical
biology, paleontology and earth science, the recent progress of
molecular biology has provided new insights into understanding how
present-day organisms have evolved with such tremendous diversity.
Molecular biological studies show us that all living forms,
including "E. coli" and human beings, derive from a single ancestor
that emerged some 4 billion years ago on Earth. This volume aims to
discuss the motifs of organismic evolution from the viewpoints of
biogeo-interactions and diversification of the genetic systems.
Based on these fundamental understandings, the last section of this
volume is devoted to human evolution that includes phylogeny of man
as well as evolution of human culture. Such comprehensive
discussion will give us a synthesized view of the evolution of
life, that is undoubtedly one of the most important problems not
only for science but also for human culture in general.
The history of research on hog cholera (HC)/classical swine fever
(CSF) can be roughly divided into three phases which are
characterized by the methods available at the time for demonstrati
ng the causati ve agent. Phase covered the period before the viral
etiology of HC was discovered by de Schweinitz and Dorset (1904)*.
Thereafter (Phase II) the detection of HC virus (HCV) was
accomplished by laborious, time-consuming and costly pig
inoculation experiments. This explains the extensive search for
methods not only for detection but also for accurate infectivity
titration as well as for applicable serological techniques to solve
urgent problems concerning the pathogenesis, diagnosis,
epidemiology and prophylaxis of HC. It was not before the late
fifties that HC research entered Phase III when fluorescent
antibody techniques offered not only the means for detection and
titration of HCV in porcine cell cultures but also for more
intensive research on hog cholera and its virus. And yet, there are
a number of questions to be answered, e. g. on the genetic and
antigenic relation of HCV to bovine viral diarrhea (BVD) virus.
There are indications that Phase IV of HC research will bear the
stamp of biotechnology. In view of this development it appears
appropriate to give an up-dating and summarizing account of HC/CSF
including comparative aspects of infections caused by structurally
related viruses. The editIon of the present volume would have been
impossible without the cooperation of several known scientists who
instantly agreed when asked for contribution.
In 1976 I wrote a monograph on lysosomes (Lysosomes: A Survey,
Springer Verlag, Vienna) that was intended as an up-to-date,
comprehensive survey. Whatever success I may have achieved then in
fulfilling that intention, even the effort now would be foolhardy.
The literature has grown so rapidly in the past decade that I
certainly could not even read all of the essential papers, let
alone understand and analyze them. My goal here, therefore, is
simply to introduce the major features of lysosomes at a level I
hope will be useful both to I;ldvanced students and to researchers
interested in obtaining a broad background. This is in keeping with
the design of the Cellular Organelles series: the series is more a
set of advanced texts than of review monographs. This design
carries with it the decision not to support each point by refer
ences to the original literature. I apologize for the injustice
involved in such a decision but feel that in any event it would be
impossibly unwieldy to cite, adequately and in a balanced manner,
the contributions of the vast network of researchers responsible
for the information upon which I draw."
Analytical Molecular Biology illustrates the importance of simple
analytical methods applied to some basic molecular biology
problems, with an emphasis on the importance of biological
problems, rather than the complexity of mathematics. First, the
book examines crucial experimental data for a specific problem.
Mathematical models will then be constructed with explicit
inclusion of biological facts. From such models, predictions can be
deduced and then suggest further experimental studies. A few
important molecular biology problems will be discussed in the order
of the complexity of the mathematical models. Based on such
illustrations, the readers can then develop their own analytical
methods to study their own problems. This book is for anyone who
knows they need to learn how to apply mathematical models to
biology, but doesn't necessarily want to, from practicing
researchers looking to acquire more analytical tools to advanced
students seeking a clear, explanatory text.
Animal cell technology is a growing discipline of cell biology
which aims not only to understand structures, functions and
behaviors of differentiated animal cells but also to ascertain
their abilities to be used for industrial and medical purposes. The
goal of animal cell technology includes accomplishments of clonal
expansion of differentiated cells with useful ability, optimization
of their culture conditions, modulation of their ability for
production of medically and pharmaceutically important proteins,
and the application of animal cells to gene therapy and artificial
organs. This Volume gives the readers a complete review of the
present state of the art in Japan. The Proceedings will be useful
for cell biologists, biochemists, molecular biologists,
immunologists, biochemical engineers and other disciplines related
to animal cell culture, working either in academic environments or
in industries of biotechnology and pharmacy.
Mass spectrometry underwent dramatic changes during the decade of
the 1980s. Fast atom bombardment (F AB) ionization, developed by
Barber and coworkers, made it possible for all mass spectrometry
laboratories to analyze polar, highly functionalized organic
molecules, and in some cases ionic, inorganic, and organometallic
compounds. The emphasis of much of this work was on molecular
weight determination. Parallel with the development of ionization
methods (molecular weight mass spectrometry) for polar biological
molecules, the increased mass range of sector and quadrupole mass
spectrometers and the development of new instruments for tandem
mass spectrometry fostered a new era in structural mass
spectrometry. It was during this same period that new instrument
technologies, such as Fourier transform ion cyclotron resonance,
radio frequency quadrupole ion trap, and new types of
time-of-flight mass spectrometers, began to emerge as useful
analytical instruments. In addi tion, laser methods useful for both
sample ionization and activation became commonplace in almost every
analytical mass spectrometry laboratory. In the last 5 years, there
has been explosive growth in the area of biological mass
spectrometry. Such ionization methods as electrospray and
matrix-assisted laser desorption ionization (MALDI) have opened new
frontiers for both molecular weight and structural mass
spectrometry, with mass spectrometry being used for analysis at the
picomole and even femto mole levels. In ideal cases, subfemtomole
sample levels can be successfully analyzed. Sample-handling methods
are now the limiting factor in analyz ing trace amounts of
biological samples."
Animal cell technology is a growing discipline of cell biology
which aims to understand the structure, function and behaviour of
differentiated animal cells, and especially the development of such
abilities as are useful for industrial purposes. These developments
range from clonal expansion of differentiated cells with useful
abilities, to optimization of cell culture on industrial scale and
modulation of the cells' abilities to produce drugs and monoclonal
antibodies. The sixth volume in this series gives a complete review
of today's state of the art in Japan, a country where this field is
especially well advanced. It will be of interest to cell
biologists, biochemists, molecular biologists, immunologists and
other disciplines related to animal cell culture, working in the
academic environment as well as in (biotechnology or
pharmaceutical) industry.
