El miembro superior es indispensable para la realización de la mayoría de las actividades laborales, lo que supone una exposición permanente a factores de riesgo biomecánicos, físicos y psicosociales, que causan la aparición de lesiones en los tejidos articulares y periarticulares del hombro, el codo, la muñeca y la mano. Los autores efectúan una revisión anatómica de la extremidad superior y de los factores de riesgo presentes en el trabajo, así como de los mecanismos fisiopatológicos que explican la aparición de los desórdenes musculoesqueléticos (DME), a fin de establecer estrategias en todos los niveles de prevención (primario, secundario y terciario) y lograr que se apliquen de forma articulada en los ambientes laborales. De esta manera, buscan velar por la salud de los trabajadores expuestos y disminuir la incidencia de la enfermedad.
El miembro superior cuenta con tres nervios principales: mediano, cubital y radial. La exposición de la extremidad superior a factores de riesgo laboral puede ocasionar lesiones en estos nervios y dar lugar a neuropatías por atrapamiento. A nivel mundial, el síndrome del túnel del carpo (stc), una neuropatía por atrapamiento del nervio mediano en la muñeca, es considerado como la enfermedad laboral más significativa. El síndrome del túnel cubital (stcu) y el síndrome del túnel radial (str), de menor incidencia y prevalencia en el ámbito laboral, representan neuropatías por atrapamiento de los nervios cubital y radial, respectivamente. Los autores llevan a cabo una revisión de los factores que provocan las neuropatías en el miembro superior y proponen estrategias de prevención en los ambientes laborales, con el fin de facilitar un manejo integral, desde el diagnóstico hasta la rehabilitación.
This is the untold story of how black saints - and the slaves who venerated them - transformed the early modern church. It speaks to race, the Atlantic slave trade, and global Christianity, and provides new ways of thinking about blackness, holiness, and cultural authority.
Frontiers in Nanomedicine offers an up-to-date understanding of nanomaterials to readers having clinical or biomolecular research interests. Scientists, both aspiring and experienced, will find, in each volume, a comprehensive overview of current molecular strategies for using nanoscale materials in medicine. This volume explains the use of nanotechnology in medicine to improve the diagnosis of disease and the role of nanoparticles in targeted drug delivery systems for theranostic applications. This volume also covers the applications of nanoparticles in breast cancer research, liver disease therapy and Alzheimer’s disease treatment.
This book provides information on synthesis, properties, and applications of carbon nanomaterials. With novel materials, such as graphene (atomically flat carbon) or carbon onions (carbon nanospheres), the family of carbon nanomaterials is rapidly growing. This book provides a state-of-the-art overview and in-depth analysis of the most important ca
Current research suggests that neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and Creutzfeldt-Jacob may be linked to disorders in protein shape referred to as protein misfolding. Continued study in this area could lead to promising advances in future treatment of these diseases. This groundbreaking text describes the latest findings regarding protein misfolding in the context of it being a marker, and perhaps a cause, in neurodegenerative diseases. Comprehensive coverage includes the diverse biochemical targets/markers for each disease, the currently limited success of drug therapies, and the cutting-edge research that could lead to more promising treatments.
Frontiers in Nanomedicine offers an up-to-date understanding of nanomaterials to readers having clinical or biomolecular research interests. Scientists, both aspiring and experienced, will find, in each volume, a comprehensive overview of current molecular strategies for using nanoscale materials in medicine. Nanomedicine and Neurosciences: Advantages, Limitations and Safety Aspects presents different aspects of nanomedicine applied to neuroscience for the diagnosis of disease and the role of nanoparticles in targeted drug delivery systems for neurodegenerative disorders. Topics covered in this volume cover the physiology of neurodegeneration, targeted therapies for Alzheimer's disease and Parkinson's disease, blood brain barrier drug delivery systems, in vivo studies of drug nanoconjugates, nanomedicine safety, and more.
Of all the parasitic diseases, leishmaniasis is one of the most diverse, with a variety of manifestations, from relatively minor cutaneous lesions to deadly visceral infections. It is also widespread, causing human disease in the Americas, Asia, Europe and Africa. The environments in which this disease occurs range from desert to tropical jungle to urban habitats. Not surprisingly, the literature on this disease is written in a variety of languages including Portuguese, Arabic, English and French among others. This book provides a synopsis in English of much of the recent research on leishmaniasis, with a focus on the epidemiology, diagnosis and treatment of the disease as described by researchers around the world, but with a focus on the research from Brazil and the Middle East.
Environmental-friendliness, issues of public health, and the pros and cons of genetically-modified crops all receive regular coverage in the world's media. This, in turn, has led to increased questioning and investigation of chemical pesticides. Stenersen's concise and timely introduction to chemical pesticides describes these compounds according to their mode of action at the cellular and biochemical level. Chemical Pesticides provides answers to questions such as why pesticides are toxic to the target organism and why pesticides are toxic to some organisms and not others. It describes how various poisons interfere with biochemical processes in organisms. The book also explores how resistance to pesticides develops, how resistance can be used to illustrate the theory of evolution, and how it can be used to produce herbicide-resistant crop plants. Legal matters and potential environmental problems are also discussed. By providing an integrated, yet simple description of modern chemical pesticides, the author provides a relevant text for professionals and students in biological disciplines such as biochemistry, medicine, agriculture, and veterinary science.
College Koreanoffers a comprehensive introduction to the Korean language designed for American students. Rogers, You, and Richards have used their many years of teaching to devise and test an approach that balances reading and writing with the spoken language. The result is a well-rounded textbook suited to a yearlong course in which students learn to conduct conversations about their own lives and interests, read texts written inhangul, and write simple compositions. The book systematically introduces basic Korean grammar, a contextualized vocabulary, and styles of speech that are sociolinguistically appropriate for college students. Each of its 26 lessons contains a dialogue or a reading, practice patterns, relevant grammar notes, and exercises. Approximately 150 Sino-Korean characters are also introduced, and complete glossaries and grammar indexes are provided.
