Book Description
The International Agency for Cancer Research (IARC) classifies asbestos as a proven human carcinogen. No amount of asbestos exposure is safe for human health. Consequently, the use of all forms of asbestos has been banned in most of the developed countries. Unfortunately, India has failed to impose such a ban. Despite the fact that a ban on mining in India is being placed for more than 20 years, mines in the private sector of India are still in operation and asbestos continues to be used in large quantities. The official reason given by both industry and government is that it is a material for the poor as it is cheap and has many good properties. Generally, people in the slum area often cook their food in the open wood fire under asbestos roofing. This results in cracking of asbestos cement roofs exposing asbestos, making it friable as the height of most rural houses roofed with asbestos cement is too small to have effective air circulation. In addition, on the roofs of Indian slums, where it is sawn and fixed by hand, it’s difficult to avoid releasing a large number of dangerous fibers. The inhabitants paint their asbestos roofing with emulsion paint which also deteriorates it, rapidly resulting in discoloration and mould growth. As a result, Asbestos related diseases are more common in the slum area. In this study, Asbestos cement sample was randomly scanned at various magnifications to identify asbestos fibers and determine how asbestos fibers are mixed with construction materials. Laboratory analyses were performed on the asbestos cement sample to establish a relationship between: i) morphology (shape of the crystals), ii) the asbestos cement mineralogical composition using SEM analyses and iii) high magnification structure of the individual fibers (fibrils), as well as iv) energy dispersive x-ray analysis of the fiber chemistry by comparison to a standard. Also, quantification analysis of fiber length and thickness was performed due to the reason that fibrogenicity and carcinogenicity of asbestos fibers are both dependent on several fiber parameters including fiber dimensions. There are several standards specified under the Factories Act and Mines Act including limits of exposure. But standards in India are only on paper. All forms of asbestos pose grave to human health. All are proven human carcinogens. There is no continued justification for the use of asbestos. Its production and use should be banned worldwide. A global ban on asbestos is needed.

Book Description
Asbestos is not just a problem of the past, nor is there an identifiable point in the future by which we can stop worrying about its legacy. In various countries around the world asbestos production and consumption continues unabated, storing up problems for the future. In countries that have banned the use of asbestos, such as the UK, the continued presence of this material in buildings public and private will have consequences for decades to come.Asbestos: the Future Risk is a special report that pulls together the historical background as to how this mineral came to be so widely used; the medical view of asbestos related diseases and their treatment; the current patterns of consumption that indicate where future claims may come from; and current practice for dealing with asbestos in the built environment, exposure to which has spread asbestos-related diseases to people outside those occupations that worked directly with asbestos.Asbestos: the Future Risk provides an all-round update on the present state of knowledge and sets out the challenges faced by claimants, governments, private companies, public authorities, lawyers and insurers.

Book Description
Cancer is a very aggressive disease and currently it has been considered a challenge to oncologists and cancer patients worldwide. Nowadays, several therapeutic strategies had improved toward last decades. Surgery is many times still the best curative treatment, mainly in early stage disease. However, Radiotherapy and chemotherapy acquired a main role in this scenario. Target therapies were introduced for medical oncology practice and are demonstrating a hallmark of a new era in cancer treatment. More recently, immunotherapy has been considered the novel cornerstone in cancer treatment. The 2nd edition of the International Manual of Oncology Practice (iMOP) emerged after the great success of the iMOP 1st edition as a reference for medical oncologists and medical residents in the field. In this edition, several chapters were revised and its addresses from the molecular issues of cancer sciences to the clinical practice in medical oncology. In addition, multiple choice questions and clinical cases were included in the main chapters in order to improve the reader learning. The book focuses systemic treatments in many areas of medical oncology, such as breast cancer, gastrointestinal, thoracic, urological oncology, head and neck tumors, bone tumors, sarcomas and palliative care. The topics herein discussed will provide the readers a step forward in the medical oncology practice understanding and give facilities for help in cancer patient treatments.

Book Description
Rapid advances and new technologies in the life sciences - such as biotechnologies in health, agricultural and environmental arenas - pose a range of pressing challenges to questions of citizenship. This volume brings together for the first time authors from diverse experiences and analytical traditions, encouraging a conversation between science and technology and development studies around issues of science, citizenship and globalisation. It reflects on the nature of expertise; the framing of knowledge; processes of public engagement; and issues of rights, justice and democracy. A wide variety of pressing issues is explored, such as medical genetics, agricultural biotechnology, occupational health and HIV/AIDS. Drawing upon rich case studies from Asia, Africa, Latin America and Europe, Science and Citizens asks: · Do new perspectives on science, expertise and citizenship emerge from comparing cases across different issues and settings? · What difference does globalisation make? · What does this tell us about approaches to risk, regulation and public participation? · How might the notion of ‘cognitive justice‘ help to further debate and practice?

Book Description
Although asbestos is no longer mined in the United States, prior and ongoing exposures to asbestos continue to contribute to respiratory diseases, including mesothelioma, lung cancer, and asbestosis. To examine ongoing issues and concerns in this field, the National Institute for Occupational Safety and Health (NIOSH) drafted a research roadmap, Asbestos Fibers and Other Elongated Mineral Particles: State of the Science and Roadmap for Research, that provides an overview of the state of the science and a plan for future research in areas including toxicology, mineralogy, epidemiology, and exposure assessment. The focus of the proposed research is on clarifying the relationship between human health effects and the physical and chemical characteristics of a wide range of elongate mineral particles. In 2008, NIOSH asked the Institute of Medicine and the National Research Council to form a committee to provide a review of the scientific and technical quality of the January 2009 draft NIOSH Roadmap document. The present volume provides the committee's assessment of the Roadmap and recommendations for strengthening its utility for NIOSH, other federal agencies, the private sector, and other stakeholders.
