Available in PDF, EPUB and Kindle. Book excerpt: When the eyeball is indented in total darkness, within less than 200 mil liseconds an oval or quarter-moon shaped spot of light is perceived in the part of the visual field corresponding to the indented region of the retina. In the seconds following, this phosphene extends across the whole visual field and alters in structure during further eyeball indentation. It is then seen as irregular large bright spots of light, finely structured moving light grains ('light nebula') and stationary bright stars. Regular geometrical patterns appear only when both eyes are indented simultaneously [1]. When the eyeball deformation is released, part of the retina again lights up for another one or two seconds and curved light lines are seen following the course of the larger retinal vessels (Fig. 1). In the following we will review the history of this phenomenon, which played an important role during the first 2200 years of vision theories and in the development of models to explain normal vision. 2. Pre-Socratic philosophers, Plato and Aristotle Alcmaeon of Croton (6-5th century B. C. ), who was a member of the Pythagoraean sect and one of the founders of Greek medicine, was the first to describe mechanical deformation of the eyeball leading to light sensa tions. According to Aristotle's pupil Theophrast of Eresos, Alcmaeon report ed that 'the eye obviously has fire within,for when the eye is struckfireflashes out' [2, p. 88].

Download or read book Hope and Suffering written by Gretchen Krueger and published by JHU Press. This book was released on 2020-03-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gretchen Krueger's poignant narrative explores how doctors, families, and the public interpreted the experience of childhood cancer from the 1930s through the 1970s. Pairing the transformation of childhood cancer from killer to curable disease with the personal experiences of young patients and their families, Krueger illuminates the twin realities of hope and suffering. In this social history, each decade follows a family whose experience touches on key themes: possible causes, means and timing of detection, the search for curative treatment, the merit of alternative treatments, the decisions to pursue or halt therapy, the side effects of treatment, death and dying—and cure. Recounting the complex and sometimes contentious interactions among the families of children with cancer, medical researchers, physicians, advocacy organizations, the media, and policy makers, Krueger reveals that personal odyssey and clinical challenge are the simultaneous realities of childhood cancer. This engaging study will be of interest to historians, medical practitioners and researchers, and people whose lives have been altered by cancer.
Download or read book New Insights Into Retinal Degenerative Diseases written by Robert E. Anderson and published by Springer Science & Business Media. This book was released on 2001-12-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1984, we have organized satellite symposia on retinal degenerations that are held in conjunction with the biennial International Congress of Eye Research. The timing and location of our Retinal Degeneration Symposia have allowed scientists and clinicians from around the world to convene and present their exciting new findings. The symposia have been arranged to allow ample time for discussions and one-on-one interactions in a relaxed atmosphere, where international friendships and collaborations could be established. The IXth International Symposium on Retinal Degeneration was held on October 9-14, 2000 in Durango, Colorado and was attended by over 100 scientists from six continents. This book contains many of their presentations. Several events of note occurred at this meeting. First, thanks to the generous support of the Foundation Fighting Blindness, we were able to sponsor the travel of 11 young scientists from six countries. Most of them have contributed chapters to this volume. The response to the travel program was so overwhelming that we will make it regular feature of our meeting. This will allow other bright, young investigators to be introduced to the world experts who study retinal degenerations. Second, about 40% of the scientists who attended this meeting were there for the first time. We believe that this indicates a growing interest in retinal degeneration research and ensures that new talent will be attracted to this important area of investigation. The symposium received support from several organizations.

Download or read book Ophthalmology and the Ageing Society written by Hendrik P.N. Scholl and published by Springer Science & Business Media. This book was released on 2013-05-29 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ageing of the world’s population is one of the major achievements of modern society. By 2050, an estimated 2 billion people will be aged 60 years or over. However, ageing poses major challenges and this is especially true for the field of ophthalmology, given that the major eye diseases – age-related macular degeneration, glaucoma, and cataract – predominantly affect the elderly. The challenges facing ophthalmology in an ageing society have not previously been addressed in a comprehensive way, although there are common denominators of the various eye diseases that affect the elderly. This book provides such a comprehensive overview encompassing epidemiology, risk factors, current treatment and prophylaxis, disability, co-morbidity, and the impact on quality of life. World leaders in their respective fields provide state-of-the-art knowledge on the geriatric aspects of ophthalmology that will help to improve the management of this growing patient population.

Download or read book The Emperor of All Maladies written by Siddhartha Mukherjee and published by Simon and Schuster. This book was released on 2011-08-09 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Pulitzer Prize and a documentary from Ken Burns on PBS, this New York Times bestseller is “an extraordinary achievement” (The New Yorker)—a magnificent, profoundly humane “biography” of cancer—from its first documented appearances thousands of years ago through the epic battles in the twentieth century to cure, control, and conquer it to a radical new understanding of its essence. Physician, researcher, and award-winning science writer, Siddhartha Mukherjee examines cancer with a cellular biologist’s precision, a historian’s perspective, and a biographer’s passion. The result is an astonishingly lucid and eloquent chronicle of a disease humans have lived with—and perished from—for more than five thousand years. The story of cancer is a story of human ingenuity, resilience, and perseverance, but also of hubris, paternalism, and misperception. Mukherjee recounts centuries of discoveries, setbacks, victories, and deaths, told through the eyes of his predecessors and peers, training their wits against an infinitely resourceful adversary that, just three decades ago, was thought to be easily vanquished in an all-out “war against cancer.” The book reads like a literary thriller with cancer as the protagonist. Riveting, urgent, and surprising, The Emperor of All Maladies provides a fascinating glimpse into the future of cancer treatments. It is an illuminating book that provides hope and clarity to those seeking to demystify cancer.
Download or read book The 71F Advantage written by National Defense University Press and published by NDU Press. This book was released on 2010-09 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes a foreword by Major General David A. Rubenstein. From the editor: "71F, or "71 Foxtrot," is the AOC (area of concentration) code assigned by the U.S. Army to the specialty of Research Psychology. Qualifying as an Army research psychologist requires, first of all, a Ph.D. from a research (not clinical) intensive graduate psychology program. Due to their advanced education, research psychologists receive a direct commission as Army officers in the Medical Service Corps at the rank of captain. In terms of numbers, the 71F AOC is a small one, with only 25 to 30 officers serving in any given year. However, the 71F impact is much bigger than this small cadre suggests. Army research psychologists apply their extensive training and expertise in the science of psychology and social behavior toward understanding, preserving, and enhancing the health, well being, morale, and performance of Soldiers and military families. As is clear throughout the pages of this book, they do this in many ways and in many areas, but always with a scientific approach. This is the 71F advantage: applying the science of psychology to understand the human dimension, and developing programs, policies, and products to benefit the person in military operations. This book grew out of the April 2008 biennial conference of U.S. Army Research Psychologists, held in Bethesda, Maryland. This meeting was to be my last as Consultant to the Surgeon General for Research Psychology, and I thought it would be a good idea to publish proceedings, which had not been done before. As Consultant, I'd often wished for such a document to help explain to people what it is that Army Research Psychologists "do for a living." In addition to our core group of 71Fs, at the Bethesda 2008 meeting we had several brand-new members, and a number of distinguished retirees, the "grey-beards" of the 71F clan. Together with longtime 71F colleagues Ross Pastel and Mark Vaitkus, I also saw an unusual opportunity to capture some of the history of the Army Research Psychology specialty while providing a representative sample of current 71F research and activities. It seemed to us especially important to do this at a time when the operational demands on the Army and the total force were reaching unprecedented levels, with no sign of easing, and with the Army in turn relying more heavily on research psychology to inform its programs for protecting the health, well being, and performance of Soldiers and their families."
