This edited book explores the use of technology to enable us to visualize the life sciences in a more meaningful and engaging way. It will enable those interested in visualization techniques to gain a better understanding of the applications that can be used in visualization, imaging and analysis, education, engagement and training. The reader will also be able to learn about the use of visualization techniques and technologies for the historical and forensic settings. The reader will be able to explore the utilization of technologies from a number of fields to enable an engaging and meaningful visual representation of the biomedical sciences. We have something for a diverse and inclusive audience ranging from healthcare, patient education, animal health and disease and pedagogies around the use of technologies in these related fields. The first four chapters cover healthcare and detail how technology can be used to illustrate emergency surgical access to the airway, pressure sores, robotic surgery in partial nephrectomy, and respiratory viruses. The last six chapters in the education section cover augmented reality and learning neuroanatomy, historical artefacts, virtual reality in canine anatomy, holograms to educate children in cardiothoracic anatomy, 3D models of cetaceans, and the impact of the pandemic on digital anatomical educational resources.

Up to about twenty-five years ago, virtually the entire field of microscopy could be overseen and even practized by any active research worker. The rapid evolution which microscopy in its broadest sense has since undergone and which has contributed greatly to our insight in many fields of biological science and medicine has, however, lead to a progressive specialisation. Both experienced investigators in clinical and biological laboratories and post graduate students, confronted with a limited number of microscopic tech niques in their daily research work, have increasing difficulty in keeping (or obtaining) a general idea of the many time-honoured and new possibilities which microscopy has to offer. This book has been written with the aim of presenting general informa tion on light microscopic techniques, at a level somewhere in between booklets like those provided by microscope manufacturers (which are often too much focussed on the production program of a particular make) and very advanced treatises with a thorough mathematical treatment of all phenomena concerned. The physically oriented texts moreover often do not sufficiently take into account the practical situation in a medical or biolog ical laboratory; on the other hand, the value of really understanding what one is doing in using a microscopic technique is often underestimated. At tempt has been made, therefore, to present sufficient background informa tion necessary for a rational application of the different microscopical tech niques in their mutual relationship."

The study ofanthropoid origins continues to be a lightning rod for research in paleoanthropology. Issuessurrounding anthropoid origins impact the higher leveltaxonomy ofprimates, adaptivescenariosfor basalprimate radiations, and the timing of origination of the major primate clades. Basic questions about anthropoid evolution remain unanswered. Where do anthropoids fit phyloge- netically among primates? Where and when did the group originate? What functional and adaptive innovations characterize anthropoids today and what is the adaptive significanceand phylogenetic history ofthese innovations? The fossil record of early anthropoid evolution has greatly improved in recent years. Developments in systematictechniques and theory, as well as the burgeoning molecular evidence, make this an ideal time for these fossil discoveries to be placed in the context of data on the relationships among living primates. There isan improved understandingoffunction and adaptation in the visual system, brain, and masticatory apparatus, key anatomical systems where anthropoid synapomorphies are concentrated. New methods for estimating visualacuity and activitypatterns in fossil primates are providing insights into the evolution ofthe visualsystem. The rapid accumulation ofinformation on color vision in primates, including new genetic evidence of possible trichro- macyin strepsirrhines, and new behavioraldata on the benefitsofcolor vision, makes this an exciting time to evaluate the role of chromatic perception in anthropoid evolution. Research into the primate visualsystem by neuroscien- tists has generated a plethoraofimportant data in recent years, making this an ideal time to bring these researchers together with anthropologists.

For the beginner or for the accomplished sinus surgeon, mastering the anatomy of the lateral nasal wall is an ongoing challenge. Even though there are excellent standard anatomical references and equally outstanding sinus courses with cadaver dissection, a reference depicting the surgical anatomy is needed. A step-by-step surgical approach on the anterior nasal spine to the anterior wall of the sphenoid is presented. The sinus surgeon is confronted with a wide range of different spaces created by the ethmoid bone. No other bone in the human body has so many anatomical variations. Four critical anatomical structures are emphasized as the foundation for a precise approach to surgery of the maxillary, anterior ethmoid, frontal, and posterior ethmoid sinuses. The goal of this book is to meet the tremendous challenge of offering an anatomical approach which will serve the sinus surgeon of every level of experience and expertise.

Magnetic resonance is a safe, non-invasive technique which can be used to produce high resolution, thin tomographic slices in any chosen plane, or true three-dimensional blocks of information. It has become the method of choice for studying the central nervous system, the vertebral column and many joints, but has not yet gained general acceptance in researching the cardiovascular system, although there are techniques for overcoming the problems of cardiac movement to produce excellent cardiovascular images. The purpose of this book is to provide the student and radiologist with a reference which can be used to identify the major structures in the body, bearing in mind that in each region a more detailed high-resolution study can usually be obtained by specialised units. The illustrations, each of which is accompanied by an explanatory line drawing, are soft tissue images based on the water content rather than the familiar X-ray shadowgram of mainly hard tissues.

During the last decades, research on spinal cord has attracted a great deal of attention because of problems such as sensory-motor and autonomic dysfunctions associated with traumatic and other injuries. Recording of spinal cord evoked potentials is one of the most promising approaches to understand the spinal cord function. However, the details of the evoked potentials and their significance in various pathological conditions are not yet fully characterized. This book summarizes new findings in the field of electrophysiology and relates this knowledge to pathology and regeneration research. It is the first one which deals in great detail with various ways to monitor spinal cord function in experimental and clinical situations. It provides an up-to-date knowledge regarding spinal cord bioelectrical activity and its modification with pharmacological agents and covers new aspects of regeneration studies, particularly the role of myelin associated inhibitory molecules. A section is devoted to clinical studies dealing with electrical activity, pathology, and current therapeutic measures. This volume will be useful both to basic and clinical neuroscientists engaged in the field of neurology, neurophysiology, neurochemistry, neurosurgery, neuropathology, and related disciplines in order to understand basic functions of the spinal cord and to stimulate further research in this rapidly advancing field.

Damage to DNA by both exogenous and endogenous sources is increasingly regarded as highly important in the initiation and progression of cancer and in the occurance of other pathological events. DNA damage caused by reactive oxygen-derived species, also called oxidative DNA damage, is most the frequent type encountered by aerobic cells. Mechanistic studies of carcinogenesis indicate an important role of this type of damage to DNA. There is also strong evidence to support the role of oxidative DNA damage in the aging process. DNA damage is opposed in vivo by repair systems. If not repaired, DNA damage may lead to detrimental biological consequences. Therefore, the repair of DNA damage is regarded as one of the essential events in all life forms. In recent years the field of DNA repair has flourished due to new findings on DNA repair mechanisms and the molecular basis of cancer. A detailed knowledge of mechanisms of DNA damage and repair, and how individual repair enzymes function may lead to manipulation of DNA repair in cells and ultimately to an increase of the resistence of human cells to DNA-damaging agents. This volume covers the most recent devlopments in this research field and contains contributions from scientists working in the fields of biochemistry, molecular biology, enzymology, biomedical science, and radiation biology.

In recent years, the techniques of electron microscopy have developed so widely and rapidly that they now cover the fields of research once the unique ll:panage of sister research techniques such as biochemistry, physiology, immunology, X-ray diffraction, etc. It is now possible to reach molecular and submolecular levels, making this technique indispensable in every type of research. Electron microscopy alone often provides enough information to solve given problems. In the field of the connective tissue matrix, knowledge of the molecular structure of collagen, pro teoglycans and elastin and their interaction has been to a large extent elucidated by electron microscopy. The field over which electron microscopy ranges in the investigation of the connective tissue matrix is so wide that the aim of this volume is to collect the main ultrastructural acquisitions disseminated in various journals and monographs in one book. The intent ofthis volume is to: (a) integrate different and new microscopic methods and review the results of such an integrative approach; (b) present a comprehensive ultrastructural account of selected aspects of the field; (c) point out gaps or controversial topics in our knowledge; (d) outline pertinent future research and expansion of the subject.

This volume represents the proceedings of the 9th International Proton Transport Conference, "Mechanisms and Consequences of Proton Transport" held in Leura, Australia, August 19 -21, 200 I. This conference has been held since 1971 every 3 to 4 years with few exceptions in association with the Congress of the International Union of Physiological Sciences. The first meeting was held in Frankfurt, Germany, at the Max-Planck'Institute. Countries hosting the conference have been Germany (twice), Sweden (twice), India, Canada, USA, Great Britain, and now Australia. Over the past 30 years participants at these Proton Transport Conferences have been principal contributors to the major discoveries in the physiology, biochemistry and pharmacology of gastric acid secretion. These include development of the H2-receptor blockers, defining the signaling pathways for the regulation of acid secretion, identifying the gastric proton pump, discovery and development of proton pump inhibitory drugs, and elucidating the physiology and biochemistry of Helicobacter pylori.

Gastrointestinal motility has evolved from an esoteric laboratory tool into a sophisti cated diagnostic technique that is now widely used clinically to guide in management of complex gastrointestinal problems. Today, it is the most rapidly growing subspecialty within gastroenterology. Previously, many of the gastrointestinal motility problems were either ignored or attributed to a disturbance of "psyche." But with the growing knowledge and understanding of how a dysfunction of the gastrointestinal muscle and nerves can cause disease, we are at the threshold of a revolution in our approach to the diagnosis and treatment of gastrointestinal motility disorders. The purpose of this book is to serve as a useful, up-to-date reference manual and guide for the diagnostic and therapeutic approach towards common adult and pediatric gastrointestinal motility problems. In order to enhance the understanding of these disor ders, a problem-oriented approach has been chosen, and wherever possible the authors have provided clinical case scenarios to illustrate their message. The emphasis has been on how to diagnose and treat motility disorders rather than to provide an encyclopedic infor mation. The reference list at the end of each chapter should enable the enthusiast to seek further information. Some of the material presented in this book has been derived from the proceedings of the annual University ofIowa College of Medicine GI Motility Symposia."

Provide a learner-centred approach to the study of A&P Human Anatomy & Physiology speaks to the way today's diverse students learn and study. In the 2nd Edition, author Erin Amerman strengthens her distinctive learner-centred approach by focusing on three unique pillars. First, Amerman uses art to present one-concept-at-a-time before bringing the distinct parts together in one summarising Big Picture figure. Second, Amerman coaches students right when they need it, beginning on page 51 where the opening module titled How To Succeed in Your Anatomy & Physiology Course appears. And finally, she provides students with ample opportunities to practice and develop critical-thinking skills through questions about case studies and real-world scenarios.

Many hormones, growth factors, and other large molecules bind to speci Jic receptors on the surface of eukaryotic cells and are rapidly taken into these cells. Current techniques of protein purification have made available sufficient amounts of these molecules so that detailed studies of their interaction with cells could be carried out. These studies have been performed on just a few types of cells, but it is clear that all types of cells carry out a_ similar internalization process. The realization that cells rapidly internalize hormones, growth factors, transport proteins, toxins, and viruses has led many investigators to address a similar series of questions: (1) What is the pathway by which macromolecules enter cells? (2) Do all macromolecules enter by the same pathway? (3) What is the function of internalization of large molecules? (4) What is the biochemical mechan ism of internalization? In this volume we have tried to provide answers to these and related questions. To do this we have asked scientists currently active in the field to contribute chapters in their special areas of interest. The selection of the material covered reflects in large part areas of active research. Because of space limitations some important areas have not been covered as fully as we would have liked in this volume, but will be covered in a future volume. Our aim has been to present a consistent view and, when disagreements exist, to point out the basis of such disagreements."

In spite of the current feelings that today only molecular DNA analysis is the exact identification method - and that, if DNA cannot be isolated, it might be better to give up the identification - the author has used for the same purpose older, classical methods from physical anthropology to forensic medicine and especially a recent method of comparison of epigenetic traits, which proved to be very useful for identification of the family related skulls in connection with historical, genealogical and other data. These multidisciplinary methods can serve the same purpose as the reference method and can be applied in similar cases all over the world. The monograph presents the identification of 18 collectively interred skulls, supposedly belonging to the Counts of Celje (15th c.), and to family members, who lived on the territory of present-day Slovenia. Their kinship is established by comparison of X-ray images of paranasal cavities (frontal and maxillary sinuses, and also orbital and nasal cavities), the shape and size of which are autosomal dominant inherited characters. The comparison also extends to numerous other, likewise inherited, epigenetic trait similarities on the skulls. This work will be an invaluable guide for the identification and verification of kinship by skulls collectively interred (in family vaults), where isolation of DNA is no longer possible, even though the skeletal remains may not be old. This work based on the latest epigenetic research, is highly relevant for modern non-genetic identification studies. It is highly recommended to: scientists working on human identification and studying heredity, forensic scientists, physical anthropologists, radiologists, stomatologists, paleopathologists, geneticists, historians and many others.

One of the early ways by which man learns about the sur rounding world is by taking to pieces an object which attracts his attention. This method, which is widely used by children, is re sorted to once again by the adult who wishes to study natural phe nomena. The method of dismantling a complete object into its parts so that it can be studied has found its widest and most suc cessful application in biology and, in particular, in the study of living cells. The cytologist studying a cell will usually have to examine its fragments, which may be dead or semiliving. In sec tions of killed cells, with the aid of the light or electron micro scope he tries to obtain some idea of the structure of the living cell. As he investigates fractions isolated from a tissue homog enate, or substances isolated from individual cells, he tries to discover the biochemical functions of the cell organoids and their components. In every case the study of degradation products of the cell (depending on the degree of degradation these may be iso lated nuclei, nucleoli, nucleolar ribosomes, ribosomal proteins and RNA, mitochondria, fragments of mitochondrial membranes, and so on) makes its own contribution to knowledge, and the infor mation obtained on different objects is mutually complementary. Among all the cell fragments obtaine,d experimentally which can make a great contribution to our knowledge of cell structure, an important place is occupied by contractile cell models.

The author John L. Fox shares his many years of teaching and surgery through more than three hundred illustrations and photographs (including over one hundred in color). Dr. Fox has published many works on neuroscience and clinical neurosurgery and is well-known for his color images of live neurosurgical anatomy as viewed through the operating microscope. Historic techniques, instrumentation and positioning, photographic techniques, cranial anatomy and the cranial flap, and intracranial anatomy as seen from the frontolateral or pterional approach are clearly discussed and illustrated from the operating (right sided) surgeons' perspective. The operations seen in this atlas for the main part involve aneurysms and some tumors. Directed toward neurosurgeons, neuroscientists, and anatomists, the book is intended to serve as an atlas of anatomy as well as a guide to clinical neurosurgery.

This detailed volume features techniques to explore the complex interface that separates the systemic circulation from the central nervous system, known as the blood-brain barrier (BBB). Beginning with an introduction to its physiology, the book continues with sections on using pluripotent stem cells in models of the BBB, co-culture, permeability and transwell models, microfluidic and chip models, as well as models to study specific BBB pathologies. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, The Blood-Brain Barrier: Methods and Protocols collects a wide range of methodologies which will aid all researchers in the fascinating world of the blood-brain barrier.

One of the main attractions of research into hypersensitivity disorders is that it brings together scientists from a very broad range of disciplines. As the most common hu man immunologic disorder, it excites the interest and concern of clinicians, geneticists, basic and clinical immunologists, molecular biologists, biochemists, and physiologists. General agreement has been forged on the the pathophysiology of the disease and the mechanisms responsible for its maintenance, but many areas remain as black boxes for which we have only hypotheses. In 1992 Vienna hosted an international symposium to consider the explosion of in formation being generated by the identification, cloning, and expression of common envi ronmental allergens: The present second international conference on the MOLECULAR BIOLOGY OF ALLERGENS AND THE ATOPIC IMMUNE RESPONSE, again jointly organized and co-chaired by Professors Alec Sehon (Winnipeg) and Dietrich Kraft (Vi enna), provided an exciting opportunity for many leaders in this field to share data, argue hypotheses and seek future opportunities to enlarge our understanding of these very com plex diseases. This symposium was co-sponsored by the International Union of Immu nological Societies (I. U. I. S. ) and the International Association of Allergology and Clinical Immunology. It was held in the hospitable and comfortably elegant surroundings of Que bec City.

New interest in light microscopy of the last few years has not been backed up by adequate general literature. This book intends to fill the gap between specialized texts on detailed topics and general introductory booklets, mostly dealing with the use of the conventional light microscope only. In this short textbook both new developments in microscopy and basic facts of image formation will be treated, including often neglected topics such as axial resolving power, lens construction, photomicrography and correct use of phase-en interference contrast systems. Theoretical background will be dealt with as far as necessary for a well-considered application of these techniques enabling a deliberate choice for the approach of a certain problem. Over 150 illustrations (photomicrographs and diagrams) complete the information on microscopy of the nineties in the biomedical field, intended for scientists, doctors, technicians and research students. Many drawings have been contributed by the illustrator R. Kreuger; the photographic work has been executed by J. Peeterse. Secretarial assistance in preparing the manuscript was given by Ms T. M. S. Pierik. Dr M. J. Pearson has corrected the English of the final text.

This book is a collection of some of the papers presented at the EMBO Lecture Course on "Lymphocyte stimulation: differential sensitivity to radiation; biochemical and immunological properties." The Course was organized with the aim of fostering interactions between photoradiobiologists and immunologists interested in the problem of DNA damage and repair studied at the lymphocyte level. The papers presented in this book are mainly centered on the problem of radiation sensitivity of lymphocytes in relation to DNA repair phenomena. The radiation biology of human lymphocytes is dominated by two phenomena: (a) high radiosensitivity of lymphocytes which die in interphase (b) PHA-induced relative radioresistance of those cells which, after stimulation, escape the interphase death and eventually die in mitosis. These phenomena constitute a good system to study some of the factors which control the response of human cells to irradiation. In addition it is possible to correlate the development of the relative radioresistance in PHA-stimulated lymphocytes with the biochemical changes connected with the transformation processes. The papers presented in this book constitute a real contribution to the scientific knowledge in this field of research and suggest that lymphocytes could be a very interesting test material useful for measuring the DNA repair capability of human cells to furnish an indication of individual radiosensitivity in man.

The aging process, like most (all?) things in the universe, is a puzzle. It is such a fundamental occurrence, common to all living things, that it ironically may be the most complicated and perplexing puzzle to solve. There are, of course, puzzles sufficient in number to occupy all the scientists and philosophers who have ever lived a thousand times over. Yet what other phenomenon affects everyone of us as much as growing old? Curiosity about the ubiquity of aging as a phenomenon, boosted perhaps by an only natural fear of that same phenomenon as an undeniable manifes tation of our own mortality, has led to the compilation of data on the aging process, which have accumulated as rapidly as the elderly who might benefit from those data. Most of the scientific data on the biology of aging are at the biochemical and physiological levels, while comparatively little information has been avail able at the anatomical level. Because of this, a two-volume set called Aging and Cell Structure was conceived, the first volume having been published in 1981 and the second volume being published concurrently with the present one on cell function. The emphasis on training of scientists and other individuals in advanced education has, during past decades, been one of increased specialization. Not merely do we specialize in physiology, anatomy, zoology, or literature, but in glomerular filtration, synaptic junctions, tree frogs of Brazil, or English poetry of the nineteenth century."

Shelley Saunders This book offers a welcome diversity of topics covering the broader subjects of teeth and the study of teeth by anthropologists. There is an impressive array of coverage here including the history of anthropological study of the teeth, morphology and structure, pathology and epidemiology, the relationship between nutrition, human behavior and the dentition, age and sex estimation from teeth, and geographic and genetic variation. Most chapter authors have provided thorough reviews of their subjects along with examples of recent analytical work and recommendations for future research. North American researchers should particularly appreciate the access to an extensive European literature cited in the individual chapter bibliographies. Physical anthropologists with even a passing interest in dental research should greet the publication of this book with pleasure since it adds to a growing list of books on how the study of teeth can tell us so much about past human populations. In addition to the archaeological applications, there is the forensic objective of dental anthropology which the editors refer to in their introduction which is dealt with in this volume. The chapters dealing with methods of sex determination, age estimation of juveniles and age estimation of adults using the teeth are exhaustive and exacting and of critical importance to both "osteoarchaeologists" and forensic anthropologists. Authors Liversidge, Herdeg and Rosing provide very clear guidelines for the use of dental formation standards in juvenile age estimation, recommendations that are so obviously necessary at this time.

"Lysosomes are now known tobe notjustacollectionofisolatedorganellesofin- terest only to the biochemist, but part ofa complex, dynamic, membranous sys- tem essential to the cell's economy." So wrote the late Dame Honor Fell and I in the preface to the first volume of Lysosomes in Biology and Pathology almost 30 years ago. We wentonto say thatresearchonthelysosomalsystematthetimewas in a state ofexplosive and chaotic growth. While the chaos has beenlargely reduced, the growthofresearch into the bi- ology ofthe lysosome remains considerable. Biologists worldwide are still fasci- nated by the diversity of activities and the interaction between the various membranous systems of the cell, both in biological and pathological situations. The present volume, edited by John Lloyd and Robert Mason, who have each made major contributions to research in this field, continues to systematize the growthofinformation in this importantarea. Taken together, the twelve chaptersofthis volume form an extensive update ofour knowledge of the biological and physiological role of the lysosomal sys- tem. The book will enhance our knowledge ofcell function and help in our un- derstanding ofthe factors that control cell metabolism in health and disease. John T. Dingle Hughes Hall Cambridge, England ix Preface Lysosomes are still orphan organelles.
