Viruses: A Very Short Introduction (Very Short Introductions)

by Dorothy H. Crawford

Viruses are big news. From pandemics such as HIV, swine flu, and SARS, we are constantly being bombarded with information about new lethal infections. In this Very Short Introduction Dorothy Crawford demonstrates how clever these entities really are. From their discovery and the unravelling of their intricate structures, Crawford demonstrates how these tiny parasites are by far the most abundant life forms on the planet. With up to two billion of them in each litre of sea water, viruses play a vital role in controlling the marine environment and are essential to the ocean's delicate ecosystem. Analyzing the threat of emerging virus infections, Crawford recounts stories of renowned killer viruses such as Ebola and rabies as well as the less known bat-borne Nipah and Hendra viruses. Pinpointing wild animals as the source of the most recent pandemics, she discusses the reasons behind the present increase in potentially fatal infections, as well as evidence suggesting that long term viruses can eventually lead to cancer. By examining our lifestyle in the 21st century, Crawford looks to the future to ask whether we can ever live in harmony with viruses, and considers the ways in which we may need to adapt to prevent emerging viruses with devastating consequences.

Visceral Pain

by Stuart M. Brierley Nick J. Spencer

The chapters in this book are based on the Visceral Pain conference in Adelaide, Australia, under the auspices of the International Federation for Neurogastroenterology and Motility in 2021. This is one of the hottest fields of science and includes mechanisms involving how the microbiome communicates with the brain and how, when disordered, these mechanisms contribute to clinical diseases such as Irritable Bowel Syndrome and Inflammatory Bowel Disease. Researchers from around the globe presented their latest findings as a review of the current state of the art in the field from both the clinical and scientific points of view. These systems are now appreciated as being critical for shaping our well-being and their disorders underlie chronic clinical conditions of significant morbidity and mortality. The author team includes long-established authorities who significantly contributed to the advances in visceral pain research over the past two decades and the new generation that will continue to contribute to advancing our understanding of the field.

Visceral Pain: From Bench to Bedside

by Hong Jiang Ming Xia Bifa Fan

Patients with chronic visceral pain present a challenge for medical providers because of their vague presenting symptoms and frequent lack of identifiable pathology. Despite this, chronic visceral pain can be a debilitating medical condition that increases morbidity and decreases quality of life; the long-term consequences of which cause significant socioeconomic burden and debility. Covering the newest trends, studies, diagnosis and treatments in visceral pain care, as well as the pain treatment strategies that have been successfully employed in the past, this book brings readers fully up to date with effective recognitions and treatments for visceral pain. The clinical evaluation and presentation of common chronic visceral pain conditions and multimodal treatment options that can be used to assist patients and providers are focused.

Vision: How It Works and What Can Go Wrong

by John E. Dowling Joseph L. Dowling

Descriptions of basic visual mechanisms and related clinical abnormalities, by a neuroscientist and an ophthalmologist.Over the past fifty years, enormous progress has been made in understanding visual mechanisms and treating eye disorders. And yet the scientist is not always aware of the latest clinical advances and the clinician is often not up to date on the basic scientific discoveries. Writing in nontechnical language, John and Joseph Dowling, a neuroscientist and an ophthalmologist, examine vision from both perspectives, providing concise descriptions of basic visual mechanisms and related clinical abnormalities. Thus, an account of the photoreceptors is followed by a consideration of retinitis pigmentosa and macular degeneration; an explanation of the retina's function is followed by details of glaucoma and diabetic retinopathy.The authors begin with the cornea and lens, which project an image on the light-sensitive elements inside the eye, the photoreceptors, and how that process can be compromised by such disorders as cataracts and corneal disease. They go on to describe, among other things, how the photoreceptors capture light; retinal and visual cortical anatomy and physiology; and higher level visual processing that leads to perception. Cortical disorders such as amblyopia are discussed as well as specific deficits such as the inability to recognize faces, colors, or moving objects. Finally, they survey the evolution of our knowledge of vision, and speculate about future advances.

Vision: A Computational Investigation into the Human Representation and Processing of Visual Information

by David Marr

Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Vision Facts: Questions about the Human Eye

by Jason Yang Pidgeon Charles

Vision Facts is a question and answer guide to the wonders of the human eye, its complex structures and the process of visual perception. It traces the journey of vision from a ray of light entering the eye to the processing done by the brain, to the development and aging of the human visual system and common disorders associated with both processes. Organized in an intuitive question-and-answer format and accompanied by clear diagrams, Vision Facts provides answers regarding your vision in a manner accessible to all who are interested. Each topic includes references to external resources such as lecture notes and research papers for those who wish to delve deeper. It is a perfect handbook for anyone who is interested in visual science, sensory processing, neuroscience, or physiology; and is an excellent reference for anyone considering a career in ophthalmology or optometry.°Some examples of the questions include the following. What is the resolution of the eye? Why do astronomers often cover flashlights with a red filter while stargazing? What is color-blindness and how does it occur? What role does vision play in the circadian rhythm? What chemical signals cause the eye to develop into its mature form? How does alcohol during pregnancy affect eye development? How well can a newborn baby see? How does being born prematurely affect vision? What is 20/20 vision? How does aging affect vision? These are all questions that are addressed in Vision Facts, along with countless more.

The Vision Zero Handbook: Theory, Technology and Management for a Zero Casualty Policy

by Karin Edvardsson Björnberg Sven Ove Hansson Matts-Åke Belin Claes Tingvall

This open access handbook provides a comprehensive treatment of Vision Zero, an innovative policy on public road safety developed in Sweden. Covering all the major topics of the subject, the book starts out with a thorough examination of the philosophy, ideas and principles behind Vision Zero. It looks at conditions for the effectiveness of the policy, principles of safety and responsibility as well as critique on the policy. Next, the handbook focuses on how the Vision Zero ideas have been received and implemented in various legislations and countries worldwide. It takes into account the way Vision Zero is looked at in the context of international organizations such as the WHO, the UN, and the OECD. This allows for a comparison of systems, models and effects. The third part of the handbook discusses the management and leadership aspects, including ISO standards, equity issues, other goals for traffic and transportation, and opportunities for the car industry. Part four delves into tools, technologies and organizational measures that contribute to the implementation of Vision Zero in road traffic. Examples of specific elements discussed are urban and rural road designs, human factor designs, and avoiding drunk and distracted driving. The final part of the handbook offers perspectives on the transfer of Vision Zero policy to other areas, ranging from air traffic to suicide prevention and nuclear energy. Vision Zero is a public road safety policy including both a long-term goal that no one shall be killed or seriously injured as a consequence of accidents in road traffic and a safety principle stating that the design and function of the road transport system shall be adapted to meet the requirements that follow from that goal. It is a new road safety paradigm which has resulted in new types of responsibilities among stakeholders, technological innovations, and new strategies and organizational measures to achieve a safe system. The road safety work based on Vision Zero has shown promising results, and although Sweden has not yet reached a safe system, the number of fatalities and severe injuries has decreased substantially.This is an open access book.
