Life in all its forms is based on nucleic acids which store and transfer genetic information. The book addresses the main aspects of synthesis, hydrolytic stability, solution equilibria of nucleosides and nucleotides as well as base modifications of nucleic acids. The author further describes their structural analogues used as therapeutic drugs, such as antivirals and anticancer agents, and prodrug strategies of nucleotides.

Der Begriff "BIONIK" wird gerne als Kunstwort gekennzeichnet, zusammengesetzt aus BIOlogie und TechNIK. Bionik stellt einerseits ein Fach dar, in dem geforscht und ausgebildet wird, und kennzeichnet andererseits eine Sichtweise, namlich die des "Lernens von der Natur fur die Technik". Daruber sind in der Zwischenzeit neben popular wissenschaftlichen Werken eine Reihe von Fachbuchern erschienen. Werner Nachtigall hat darin mit der 2. Auflage seines bei Springer erschienenen Buchs "BIONIK - Grundlagen und Beispiele fur Ingenieure und Naturwissenschaftler" einen Meilenstein gesetzt. In diesem Buch kennzeichnet er die Untergliederung des Fachs und bespricht detailliert dessen Forschungsgegenstande. Dagegen fehlte bislang eine Darstellung, die sich mit den erkenntnistheoretischen Grundlagen wie mit der pragmatischen Vorgehensweise der Bionik systematisch befasst, die ja mit der ihr eigenen Prinzip-Abstraktion zwischen der belebten Welt als Vor-Bild und der technischen Umsetzung als Ab-Bild vermitteln will. Das vorliegende Werk schliesst diese Lucke mit drei grossen Abschnitten: Biologische Basis: Erforschen, Beschreiben, Beurteilen. - Abstraktion biologischer Befunde: Herausarbeiten allgemeiner Prinzipien. - Umsetzung in die Technik: Prinzipvergleich, Konzeptuelles, Vorgehensweise.

Die neu uberarbeitete und erweiterte Rontgenfibel dient dem angehenden Radiologen als Einfuhrung und Hilfestellung in den verschiedenen Disziplinen seines Fachgebiets.

Multiple sclerosis is the most common neurological cause of debilitation in young people; it affects approximately 85,000 people in the UK, 400,000 people in the US and approximately 2.5 million people worldwide. The disease commonly manifests in the second or third decade of life, and in most cases it leads to progressive disability, which explains its enormous impact on the economy (estimated at around GBP1.4 billion annually). The disease is incurable and the precise causes are still unknown. Part of the Oxford Neurology Library series, this practical pocketbook summarises the latest understanding of what might cause the disease, the methods of diagnosis and assessment, and current management techniques. The book also includes chapters on variants of multiple sclerosis, on childhood-onset disease and future therapies. This pocketbook will serve as an invaluable reference for trainee neurologists, consultants needing rapid access to core facts, interested general practitioners and specialist MS nurses.

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).

This book combines orthopedists' and radiologists' perspectives to provide a comprehensive overview of the rapidly expanding use of ultrasound in orthopedic surgery. It also highlights the growing awareness of the potential of this non-invasive and portable, real-time imaging tool, which has led to its inclusion in the minimally invasive toolkit of upper limb surgeons.The book is divided into five parts - shoulder, elbow, forearm, hand and wrist and fingers. Each part focuses on a particular anatomic region or joint, carefully analyzing the sonoanatomy of its nerves, tendons and bones. For each region, experienced experts illustrate how to perform specific techniques under ultrasound control, ranging from classic procedures, like carpal tunnel release, to the treatment of less common conditions. Covering all the basic and practical aspects of this innovative, multi-disciplinary approach, as well as future perspectives, this unique book is a must-read for all orthopedists, radiologists, sports physicians and physiotherapist wanting to gain insights into this promising field.

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 open access book is only an introduction to show that radiation and radioisotopes (RI) are premier tools to study living plant physiology which leads to new findings. Who had ever imagined that we could see water in a plant? Who had ever imagined that we could see ions moving toward roots in solution? Who had ever imagined that we could see invisible gas (CO2) fixation and movement in a plant? These studies demonstrated for the first time that water, ions and gas can be visualized in living plants, which could be hardly seen by anyone before. This publication summarizes the results obtained by Nakanishi's lab in The Univ. of Tokyo, based on her original concept and her original tools or systems. It is useful for professional scientists, plant physiologist, and those studying plant imaging. The chapters demonstrates the innovative imaging work of the author, using radioactive tracers and neutron beam to follow the absorption and transport manner of water as well as major, minor, and trace elements in plants. Through these studies the author developed a real-time macroscopic and microscopic imaging system able to apply commercially available gamma- and beta-ray emitters. The real-time movement of the elements is now possible by using 14C, 18F, 22Na, 28Mg, 32P, 33P, 35S, 42K, 45Ca, 48V, 54Mn, 55Fe, 59Fe, 65Zn, 86Rb, 109Cd, and 137Cs. The imaging methods was applied to study the effect of 137Cs following 3/11 Fukushima Daiichi nuclear plant accident, which has revealed the movements of radiocesium in the contaminated sites.

Bioenhancers have been used in Ayurveda historically and are now being investigated for their pharmacological effi cacy. Herbal bioenhancers work on the gastrointestinal tract to improve absorption and drug bioavailability by acting on the drug metabolic process. Many herbal drugs show low activity due to their poor lipid solubility or improper molecular size. Piperine, gingerol, naringin, quercetin, niaziridin, glycyrrhizin, allicin, curcumin, genistein and others are able to enhance the bioavailability of active pharmaceuticals. This book details various facets of herbal bio-enhancers in a single comprehensive text.

Drug resistance in cancer, whereby a proportion of cancer cells evades chemotherapy, poses a profound and continuing challenge for the effective treatment of cancer. The principles underlying the biological mechanisms behind this phenomenon are clearly understood and explained in this volume. However, a deeper understanding of drug resistance requires a quantitative appreciation of the dynamic forces that shape tumour growth, including spontaneous mutation and selection processes. The authors seek to explain and to simplify these complex mechanisms, and to place them in a clinical context. Clearly explained mathematical models are used to illustrate the biological principles and provide an insight into tumour development and the effectiveness and limitations of drug treatment. It is suitable for those with a non-mathematical background and aims to enhance the effectiveness of cancer therapy.

It also describes how the impact of transport processes is accounted for using kinetically controlled process paths.

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.

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.
