Download or read book HPV and Cancer written by James A. Radosevich and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: “HPV and Cancer” is a concise read that covers all aspects of the Human Papilloma Virus as it relates to human cancers. While written by professionals, it design to be understandable by those that are not in the field, yet it has the technical details that professionals want to stay abreast of this changing field. The book starts out the history of HPV and progresses into the molecular biology of the virus and our current understand of the structure and functions of the proteins and genes it encodes. We then look at the dynamic trends of this infectious agent in the human population, how it interacts with human cells, and the role it plays with other organisms to produce both benign and malignant tumors. Lastly, there is a discussion about a new vaccine for HPV and the hopes that are held by many to change the trends with this virus and the associated cancers it produces.

This book was released on 2006-06-30 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of science the opening up of a new observational or experimental window is always followed by an increase in knowledge of the subject concerned. This is also the case with the subject of this book, ultraviolet radiation (hereafter UV). In principle, the ultraviolet range might be just one more of these windows, of no particular importance. However, the energy per UV photon provides the main peculiarity, its magnitude being great enough to produce important ch- ical reactions in the atmospheres of planets and satellites, thereby a?ecting the transmission of this radiation to the ground. The Sun is the main natural source of UV radiation in the Solar System and our planet is the body where its in?uences can be best tested and the only one where its relation with life can be studied. However, the terrestrial atmosphere blocksmostofthephotonsinthiselectromagneticrangeandastronomershavehad to develop various techniques (balloons, planes and rockets) to cross this barrier and access the information. These tools have been used in parallel to investigate the physical properties of the terrestrial atmosphere and the interaction of its constituents with light. This book will addresses most of these topics.
Download or read book Physical Activity and Cancer written by Kerry S. Courneya and published by Springer Science & Business Media. This book was released on 2010-11-26 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores in depth the relation between physical activity and cancer control, including primary prevention, coping with treatments, recovery after treatments, long-term survivorship, secondary prevention, and survival. The first part of the book presents the most recent research on the impact of physical activity in preventing a range of cancers. In the second part, the association between physical activity and cancer survivorship is addressed. The effects of physical activity on supportive care endpoints (e.g., quality of life, fatigue, physical functioning) and disease endpoints (e.g., biomarkers, recurrence, survival) are carefully analyzed. In addition, the determinants of physical activity in cancer survivors are discussed, and behavior change strategies for increasing physical activity in cancer survivors are appraised. The final part of the book is devoted to special topics, including the relation of physical activity to pediatric cancer survivorship and to palliative cancer care.

This book was released on 1999-03-31 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human health as well as aquatic and terrestrial ecosystems are threatened from increa sing levels of environmental radiation of various sources, many of them of anthropoge nic causality: large areas of the former Soviet Union suffer from radioactive pollution, in particular after the Chemobyl accident; the increase in the incidence of UVB radiati on at the Earth's surface as a result of a progressive depletion of stratospheric ozone is a global problem that requires international concerted actions; in areas of former uranium mining the natural radiation level is substantially increased due to elevated radon levels; a growing portion of the population involved in air traffic is exposed to increased levels of natural radiation; and with the International Space Station an increasing number of astronauts will be exposed to the complex field of cosmic radiation. To estimate the corresponding risks, a better knowledge of the underlying radiobiological mechanisms at the molecular, cellular and system level is required. This book is the result of a multidisciplinary effort to discuss the current state of knowledge of the fundamental processes that result from interactions of environmental radiation -ionizing as well as UV radiation -with living matter and the existing radiati on protection concepts, and then to define future research work needed as fundamental information for the assessment of risks from increased levels of environmental radiation to human health and ecosystem balance. It comprises the key lectures and statements presented at the NATO Advanced Research Workshop.

Download or read book Solar Ultraviolet UV Radiation Exposure in Outdoor Working Environment During Cold Months written by Nanaobaayaa Owusu and published by . This book was released on 2022 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professions that are predominantly based outdoors have the risk of workers being exposed to solar ultraviolet (UV) radiation every day and during every season. Multiple studies have been conducted on outdoor workers' UV exposure during spring and summer months, but studies detailing their exposure during winter months are rare. The purpose of this study was to assess the UV exposure of groundskeepers employed at East Carolina University (ECU) during cold seasons (fall, winter, spring) compared to the summer season and to determine if UV exposure during cold seasons exceeded the Threshold Limit Values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH) as occupational exposure limits. Area monitoring of UV radiation was conducted to measure the UV effective irradiance (UVeff) using a weatherproof erythema UV detector and a digital data-logging radiometer. Ambient temperature was also collected using the OSHA-NIOSH Heat Safety Tool app. Data were collected for one year in order to have data for every season. Data analysis was conducted using analysis of variance (ANOVA) to compare UVeff by month and season, and using Pearson correlation coefficient to analyze the strength and direction between UVeff and ambient temperature. Results showed that hourly and daily UV exposures exceeded the 1-hr and 8-hr TLVs, respectively, during cold months. The hourly TLV exceedance percentages for November, December, January and February were 78.0%, 62.7%, 73.4% and 74.3%, respectively. December had the lowest hourly (0.0020 ± 0.0018 mW/cm2) and daily (0.0020 ± 0.0006 mW/cm2) mean UVeff but 62.7% and 100% of the hourly and daily data still exceeded the 1-hr and 8-hr TLVs. The seasonal average UVeff for summer (0.0095 ± 0.0025 mW/cm2) was significantly higher than winter (0.0034 ± 0.0017 mW/cm2). The seasonal average UVeff for fall (0.0044 ± 0.0017 mW/cm2) compared to the summer is much lower and is closer to the winter average. The seasonal average UVeff for spring (0.0096 ± 0.0026 mW/cm2) compared to the summer is slightly higher and is also higher than the winter and fall averages. Overall, the UVeff positively correlates with the ambient temperature, as expected. Study findings demonstrate that groundskeepers and other outdoor workers, as well as the general public, should continue to use preventive measures to reduce UV exposures during the cold months to reduce risk to UV-related adverse health effects.
Download or read book Solar and Ultraviolet Radiation written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 1992-01-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates carcinogenic risks associated with human exposure to solar radiation and to ultraviolet radiation from medical and cosmetic devices general illumination and industrial sources. The main objective of the evaluation was to determine whether enough evidence is available to decide which segments of the radiation spectrum are responsible for its adverse effects. To this end, particular attention is given to data that shed light on the distinctive carcinogenic activity of ultraviolet A B and C radiation. In evaluating carcinogenic potential the report also considers the importance of human constitutional risk factors such as skin type hair and eye color and specific subtypes of exposure such as occupational and recreational exposures. More than 1000 studies were critically assessed. On the basis of a large body of evidence from human and experimental studies, the monograph concludes that solar radiation is carcinogenic to humans causing cutaneous malignant melanoma and nonmelanocytic skin cancer. Evidence for the carcinogenicity of ultraviolet A, B, and C radiation was judged sufficient in experimental animals. All three segments of the radiation spectrum were classified as probably carcinogenic to humans. Use of sunlamps and sunbeds entails exposures that are probably carcinogenic to humans. The carcinogenicity of exposure to fluorescent lighting could not be determined. Studies of topical sunscreens are reviewed in an appendix, which concludes that although effective in preventing sunburn little is known about their protective value against harmful immuno-logical changes photo-ageing or skin cancer.
Download or read book Challenges in Sun Protection written by Christian Surber and published by . This book was released on 2021 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times - initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.
Download or read book Some Drinking water Disinfectants and Contaminants Including Arsenic written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC. This book was released on 2004 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.
