It was one of the great moments of humanity when Wilhelm Conrad Roentgen (1845- 1923) discovered a new kind of radiation on 8 November 1895. He himself modestly called them "X-rays". Roentgen's name and his rays became world famous. On 10 December 1901, Roentgen received the first Nobel Prize in Physics. X-rays have lost none of their appeal since then. They still permeate all areas of science, technology and medicine and accompany us in our everyday lives. However, Roentgen's scientific work cannot be reduced to this one great discovery alone. He was an excellent natural scientist, and his spirit of research is still an example for many scientists today. Roentgen's very special interest in precision physics is also more topical than ever. This carefully curated volume offers a multifaceted view of an outstanding natural scientist and provides insights into his personal legacy.

This classroom-tested textbook is an innovative, comprehensive, and forward-looking introductory undergraduate physics course. While it clearly explains physical principles and equips the student with a full range of quantitative tools and methods, the material is firmly grounded in biological relevance and is brought to life with plenty of biological examples throughout. It is designed to be a self-contained text for a two-semester sequence of introductory physics for biology and premedical students, covering kinematics and Newton’s laws, energy, probability, diffusion, rates of change, statistical mechanics, fluids, vibrations, waves, electromagnetism, and optics. Each chapter begins with learning goals, and concludes with a summary of core competencies, allowing for seamless incorporation into the classroom. In addition, each chapter is replete with a wide selection of creative and often surprising examples, activities, computational tasks, and exercises, many of which are inspired by current research topics, making cutting-edge biological physics accessible to the student.

The natural, biological, medical, and related sciences would not be what they are today without the microscope. After the introduction of the optical microscope, a second breakthrough in morphostructural surface analysis occurred in the 1940s with the development of the scanning electron microscope (SEM), which, instead of light (i. e. , photons) and glass lenses, uses electrons and electromagnetic lenses (magnetic coils). Optical and scanning (or transmission) electron microscopes are called "far-field microscopes" because of the long distance between the sample and the point at which the image is obtained in comparison with the wavelengths of the photons or electrons involved. In this case, the image is a diffraction pattern and its resolution is wavelength limited. In 1986, a completely new type of microscopy was proposed, which, without the use of lenses, photons, or electrons, directly explores the sample surface by means of mechanical scanning, thus opening up unexpected possibilities for the morphostructural and mechanical analysis of biological specimens. These new scanning probe microscopes are based on the concept of near-field microscopy, which overcomes the problem of the limited diffraction-related resolution inherent in conventional microscopes. Located in the immediate vicinity of the sample itself (usually within a few nanometers), the probe records the intensity, rather than the interference signal, thus significantly improving resolution. Since the most we- known microscopes of this type operate using atomic forces, they are frequently referred to as atomic force microscopes (AFMs).

The papers and reviews in the present volume are in part regular contributions submitted for publication in Biological Trace Element Research, and in part invited papers from participants of the International Symposium "Present Status and Perspectives of Sele- nium in Biology and Medicine," held on May 2 and 3, 1987, at the Eu- ropean Academy, Nonnweiler /Trier, FRG. The Symposium focused on ecological and biomedical aspects of selenium with emphasis on the manifestations of selenium deficiency in different countries, the distribution of selenium in human organs and body fliuds, the roles of selenium in health and disease, its anti carcinogenic action, effects of supplementation, and therapeutic applications. Organized jointly by the International Association of Bioinor- ganic Scientists and BioSynopsia, a Nonprofit Subsidiary of the Tech- nology Center, Stuttgart, the scientific board consisted of Professors W. Hartfiel, Bonn, FRG, G. N. Schrauzer, La Jolla, CA, USA, and H. Zumkley, Muenster, FRG.

An einem der Geschichte der Krebsforschung entnommenen Fall wird untersucht, wie sich Wissensentwicklung zum Wandel sozialer Formen des Forscherverkehrs verhalt und welche Rolle dabei wissenschaftliche Kontroversen spielen: Sie zersetzen nicht allein uberkommene Paradigmen, sondern uberdies die gegebenen sozialen Gliederungen und schaffen so Bedingungen fur den Wandel derselben (Disziplinen, Institutionen). Dieser Ansatz erlaubt die Abwehr eines Konzeptes, wonach die Schliessung einer Kontroverse auf die Favorisierung einer der strittigen Positionen hinauslauft. Ein solcher Prozess wird von Forschern eingeleitet, die das Verhaltnis gegeneinander vertretener Konzepte zu harmonisieren trachten, ohne dabei auf eine transdisziplinare bzw. theoretisch schlussige Vermittlungsbasis zu verweisen.

Literature and Medicine: A Practical and Pedagogical Guide is designed to introduce narrative medicine in medical humanities courses aimed at pre-medicine undergraduates and medical and healthcare students. With excerpts from short stories, novels, memoirs, and poems, the book guides students on the basic methods and concepts of the study of narrative. The book helps healthcare professionals to build a set of skills and knowledge central to the practice of medicine including an understanding of professionalism, building the patient-physician relationship, ethics of medical practice, the logic of diagnosis, recognizing mistakes in medical practice, and diversity of experience. In addition to analyzing and considering the literary texts, each chapter includes a vignette taken from clinical situations to help define and illustrate the chapter's theme. Literature and Medicine illustrates the ways that engagement with the humanities in general, and literature in particular, can create better and more fulfilled physicians and caretakers.

This uniquely accessible volume challenges professionals to understand-and help correct-health disparities, both at the patient level and in their larger social contexts. Dedicated to eradicating this ongoing injustice, contributors focus on marginalized populations, the role of healthcare systems in perpetuating inequities, the need for deeper engagement and listening by professionals, and the need for advocacy within professional education and the political/policy arena. The compelling case narratives at the core of the book illustrate the interrelated biopsychosocial components of patients' health problems and the gradations of learning needed for practitioners to address them effectively. The book's tools for developing a health disparities curriculum include a selection of workshop exercises, facilitator resources, and a brief guide to writing effective case narratives. A sampling of the narratives: "Finding the Person in Patient-Centered Health Care" (race/ethnicity/culture). "The Annual Big Girl / Big Boy Exchange" (gender). "Just Give Me Narcan and Let Me Go" (poverty/addiction). "Everyone Called Him Crazy" (immigration). "Adrift in the System" (disability). "Aging out of Pediatrics" (mental illness and stigma). "Time to Leave" (LGBT) A work of profound compassion, Health Disparities will be of considerable interest to researchers and practitioners interested in public health, population health, health disparities, and related fields such as sociology, social work, and narrative medicine. Its wealth of educational features also makes it a quality training text. "I was impressed when I read Health Disparities: Weaving a New Understanding through Case Narratives. As a patient who has experienced unpleasant situations in health care, I was moved to see that it was emotional and personal for the writers. The book confirms for me that the time is now for change to take place in our health care systems. I see this book as a light that can shine bright in the darkest places of health care. The editors have assembled a powerful book that provides all health professionals with specific steps they can take towards addressing and then eventually eliminating health disparities. A few steps that I really connected with were improving critical awareness, delivering quality care, listening and empathizing with patients and families, and advocating for changes. I recommend that anyone interested in working to improve health care obtain a copy of this book-it's filled with useful information that every medical professional should know. The book reminds me of a quote by Wayne Dyer, 'When you change the way you look at things, the things you look at change.'" -Delores Collins, Founder and Executive Director, A Vision of Change Incorporated, Certified Community Health Worker.

For over thirty years, rodents have been used in the study of many human and animal diseases. The rat in particular continues to serve as an experimental model for drug safety and efficacy tests for the treatment of neurological disorders, heart disease, diabetes, breast, liver and other cancers. With the more recent advent of transgenic technology, an impressive amount of new knowledge about transmissible spongiform encephalopathies has been accumulated. It is likely that the principles learned from the study of these prion diseases will be applicable to elucidating the causes of more common neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases. As a result of this and, more importantly, because of increasingly complicated legislation governing the use of animals in regulated procedures, there is a need for experimenters (both experienced and those new to the laboratory) to improve their skills continuously and to become au fait with all aspects of preparatory techniques. The Rat Nervous System provides an accessible guide to the dissection and perfusion of rats, placing particular emphasis on the preparation of nervous tissue for further study in the laboratory including biochemical analysis and microscopic study. Logically structured with highly illustrated chapters covering gross anatomy, anatomy of the nervous system, anaesthesia, biological fixation and tissue extraction, the book provides a comprehensive introduction to those techniques required to provide consistent, high-quality tissues for subsequent investigation. Animal husbandry of a high standard, together with minimisation of discomfort, is essential if the information sought by the investigator is to be valid and reproducible; an overview of these topics is therefore also incorporated in this volume.
