This book was released on 2004 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method for virus analysis has been indicated for years. This situation has reached a new and emerging viruses that tax present detection methods. Adding the cost of current methods to analyze large numbers of samples and a clear and urgent situation has developed. Fortunately, a new means for detecting the present or absence of viruses has been developed that capitalizes on the fundamental physical properties associated with these tiny microbes. The Integrated Virus Detection System (IVDS) utilizes exquisite, but regular methods, to purify and concentrate samples for sizing and counting using the usual methods of Differential Mobility Analysis and Condensation Particle Counting. Thus a new method that is essentially a virus particle counter has been invented, patented and demonstrated for a wide range of both enveloped and non-enveloped viruses. The invention is described and examples illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: The detection and analysis of viruses have been goals of science for more than 70 years, following the first real evidence that a new type of microorganism was responsible for diseases in man and animals. These new microbes were smaller than bacteria, which have now been well documented, classified, and studied. Their small size made classifying the new microbes more difficult, and the field of virology has been advanced by biochemical techniques rather than by direct examination. Advancements in electron microscopy in more recent times have made advances in this area, and much has been reported on the physical features of more than 21 virus families. All these historic techniques are time consuming and require special knowledge and specialized chemicals and preparations to be successful. Capitalizing on the physical characteristics, it was possible to separate the families and count the individual viruses in a new and dramatic way, using easily obtained materials and simple-to-operate techniques. The only materials used in the Integrated Virus Detection System (IVDS) are a buffer, CO2 gas, and butanol. The work in this report presents the advances in the concentration and counting phases of IVDS. Results indicate a practical, easy to use device, which can count viruses in near real time. The JVDS can, in its final configuration, be expected to analyze a sample, count the viruses present, and give a preliminary identification for all viruses.

Book Synopsis Integrated Virus Detection by : Charles H. Wick
Download or read book Integrated Virus Detection written by Charles H. Wick and published by CRC Press. This book was released on 2014-11-13 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple viruses can be detected concurrently using the Integrated Virus Detection System (IVDS). Integrated Virus Detection describes this technology and provides many examples of applications including a chapter on viruses found in honeybees with descriptions of seasonal and yearly variation. This straightforward technology can be used to detect known, unknown, and unsequenced viruses collected from environmental and other complex biological sources. This book summarizes more than ten US patents issued for the invention of the IVDS, which is the common name of the electrospray–differential mobility analyzer method. The IVDS is powering mankind’s ability to rapidly detect, measure, and monitor viruses as well as virus-like particles. Three facts make rapid detection possible: virus size, which ranges from 20 to 800 nm.; disparity in each virus species’ particle size thus allowing size data to be used for detection and preliminary identification; and the fact that virus particle density is distinct from other nanoparticles. The IVDS can ascertain the absence of virion particles, thus presenting compelling evidence of a true negative, which is useful in verifying decontamination and other processes. In addition, large numbers of samples may be processed in an automated fashion, providing an excellent means to prescreen them for judicious targeting of subsequent tests such as PCR or the discriminating method for identifying microbes, which is mass spectrometry proteomics.* The book is helpful to anyone interested in virus detection, especially in situations where many viral types may coexist. *Identifying Microbes by Mass Spectrometry Proteomics (CRC Press 2013)
Book Synopsis Virus Detection: Limits and Strategies by :
Download or read book Virus Detection: Limits and Strategies written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid detection of virus particles is a vexing issue to the military and public health communities. The need for a rapid and trustworthy virus detector remains an urgent and continuing requirement for commanders requiring an assurance that they have early warning from these threats. This short report presents a historical summary, with references, of methods used to extract, purify, and concentrate viruses. Working with viruses is not an easy job. The requirement for detection was identified nearly 60 years ago and just now is seeing an approach with the evolution of the Integrated Virus Detector System (IVDS) device to undertake this exacting and difficult task. This work expounds a new methodology - IVDS. The IVDS utilizes a physical process to detect viruses. This is a departure from the traditional approaches that historically have utilized obscure chemical reactions, complicated reagents and other exacting and difficult procedures for detection. The IVDS is based in four physical stages which are collection, separation, purification, and detection. Development and risks are discussed. An IVDS development schedule and costs are given that could lead to an advance prototype in two years. The IVDS system promises a very sensitive, broad spectrum "generic" virus detector free from reagent based reactions, simple to operate, and providing a capability for continuous monitoring and recording of virus levels in the outdoor bioaerosol.

Book Synopsis Digital Contagions by : Jussi Parikka
Download or read book Digital Contagions written by Jussi Parikka and published by Peter Lang. This book was released on 2007 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital Contagions is the first book to offer a comprehensive and critical analysis of the culture and history of the computer virus phenomenon. The book maps the anomalies of network culture from the angles of security concerns, the biopolitics of digital systems, and the aspirations for artificial life in software. The genealogy of network culture is approached from the standpoint of accidents that are endemic to the digital media ecology. Viruses, worms, and other software objects are not, then, seen merely from the perspective of anti-virus research or practical security concerns, but as cultural and historical expressions that traverse a non-linear field from fiction to technical media, from net art to politics of software. Jussi Parikka mobilizes an extensive array of source materials and intertwines them with an inventive new materialist cultural analysis. Digital Contagions draws from the cultural theories of Gilles Deleuze and Félix Guattari, Friedrich Kittler, and Paul Virilio, among others, and offers novel insights into historical media analysis.
Book Synopsis Strengthening Forensic Science in the United States by : National Research Council
Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

This book was released on 2017-09-28 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.
Book Synopsis CRC Handbook of Viruses by : Horace M. Mazzone
Download or read book CRC Handbook of Viruses written by Horace M. Mazzone and published by CRC Press. This book was released on 1998-05-13 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a distinct class of macromolecules, viruses are continually being studied in order to determine their properties. Following a knowledge of host-range infectivity, the particle mass-molecular weight of the virus and related properties - including size, shape, sedimentation, and diffusion coefficients - are also important characterizations. In the literature, these values have been determined for many viruses, and a variety of techniques are available by which such properties may be analyzed. Until now, there has been no single source for such information that the interested investigator may consult, and no databases provided this kind of information. CRC Handbook of Viruses: Mass-Molecular Weight Values and Related Properties corrects this deficiency by presenting such data for all classes of viruses; centering on viruses, their molecular weight, and their related properties; and acquainting the investigator to many methods for obtaining the mass-molecular weight value of viruses. This singular study explains the variety of methods available to the researcher as well as provides examples of each method. Molecular weight values are accessed directly from the book, saving the investigator a tedious search through the range of literature. Chapters discuss: Viruses as infectious agents and their role in establishing the relatively new discipline of molecular biology Essential components of viruses, protein, and nucleic acid - considering their discovery, nature, structural organization, and the forming of viruses from nucleoproteins Basic aspects of virus purification, preparative centrifuge, and various purification methods Basic aspects of crystallography, including procedures, x-ray analysis of the viral protein component, the arranging of subunits, and the composition of the intact virus Sedimentation experiments and studies used to obtain molecular weight Sedimentation and diffusion coefficients integral to the basic Svedberg equation Sedimentation equilibrium procedures The new Beckman Optima series of analytical ultracentrifuges Scattering studies, including small angle x-ray, small angle neutron, classical light scattering, and electron microscopy The renaissance of instrumentation in classical light scattering techniques Cold neutron facilities currently being set into operation by government laboratories Sizing and solvation of viruses in solution - their "natural environment" Critical modeling experiments Facilities and instrumentation for molecular weight studies - including the high voltage transmission electron microscope for obtaining mass values of viral inclusion bodies CRC Handbook of Viruses serves the: Researcher seeking values of virus molecular weight and related parameters Investigator getting started in virology and seeking information on physical chemical procedures Student interested in viruses as infectious agents

Download or read book Immunization Safety Review written by Institute of Medicine and published by National Academies Press. This book was released on 2003-11-26 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Immunization Safety Review Committee was established by the Institute of Medicine (IOM) to evaluate the evidence on possible causal associations between immunizations and certain adverse outcomes, and to then present conclusions and recommendations. The committee's mandate also includes assessing the broader societal significance of these immunization safety issues. While all the committee members share the view that immunization is generally beneficial, none of them has a vested interest in the specific immunization safety issues that come before the group. The committee reviews three immunization safety review topics each year, addressing each one at a time. In this fifth report in a series, the committee examines the hypothesis that exposure to polio vaccine contaminated with simian virus 40 (SV40), a virus that causes inapparent infection in some monkeys, can cause certain types of cancer.

Download or read book Preventing HIV Transmission written by National Research Council and Institute of Medicine and published by National Academies Press. This book was released on 1995-09-14 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses the interface of two major national problems: the epidemic of HIV-AIDS and the widespread use of illegal injection drugs. Should communities have the option of giving drug users sterile needles or bleach for cleaning needs in order to reduce the spread of HIV? Does needle distribution worsen the drug problem, as opponents of such programs argue? Do they reduce the spread of other serious diseases, such as hepatitis? Do they result in more used needles being carelessly discarded in the community? The panel takes a critical look at the available data on needle exchange and bleach distribution programs, reaches conclusions about their efficacy, and offers concrete recommendations for public policy to reduce the spread of HIV/AIDS. The book includes current knowledge about the epidemiologies of HIV/AIDS and injection drug use; characteristics of needle exchange and bleach distribution programs and views on those programs from diverse community groups; and a discussion of laws designed to control possession of needles, their impact on needle sharing among injection drug users, and their implications for needle exchange programs.

Book Synopsis Improving Diagnosis in Health Care by : National Academies of Sciences, Engineering, and Medicine
Download or read book Improving Diagnosis in Health Care written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2015-12-29 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. According to Improving Diagnosis in Health Care, diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients. It is likely that most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences. Diagnostic errors may cause harm to patients by preventing or delaying appropriate treatment, providing unnecessary or harmful treatment, or resulting in psychological or financial repercussions. The committee concluded that improving the diagnostic process is not only possible, but also represents a moral, professional, and public health imperative. Improving Diagnosis in Health Care, a continuation of the landmark Institute of Medicine reports To Err Is Human (2000) and Crossing the Quality Chasm (2001), finds that diagnosis-and, in particular, the occurrence of diagnostic errorsâ€"has been largely unappreciated in efforts to improve the quality and safety of health care. Without a dedicated focus on improving diagnosis, diagnostic errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity. Just as the diagnostic process is a collaborative activity, improving diagnosis will require collaboration and a widespread commitment to change among health care professionals, health care organizations, patients and their families, researchers, and policy makers. The recommendations of Improving Diagnosis in Health Care contribute to the growing momentum for change in this crucial area of health care quality and safety.
Book Synopsis The Hidden Epidemic by : Institute of Medicine
Download or read book The Hidden Epidemic written by Institute of Medicine and published by National Academies Press. This book was released on 1997-03-28 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States has the dubious distinction of leading the industrialized world in overall rates of sexually transmitted diseases (STDs), with 12 million new cases annually. About 3 million teenagers contract an STD each year, and many will have long-term health problems as a result. Women and adolescents are particularly vulnerable to these diseases and their health consequences. In addition, STDs increase the risk of HIV transmission. The Hidden Epidemic examines the scope of sexually transmitted infections in the United States and provides a critical assessment of the nation's response to this public health crisis. The book identifies the components of an effective national STD prevention and control strategy and provides direction for an appropriate response to the epidemic. Recommendations for improving public awareness and education, reaching women and adolescents, integrating public health programs, training health care professionals, modifying messages from the mass media, and supporting future research are included. The book documents the epidemiological dimensions and the economic and social costs of STDs, describing them as "a secret epidemic" with tremendous consequences. The committee frankly discusses the confusing and often hypocritical nature of how Americans deal with issues regarding sexualityâ€"the conflicting messages conveyed in the mass media, the reluctance to promote condom use, the controversy over sex education for teenagers, and the issue of personal blame. The Hidden Epidemic identifies key elements of effective, culturally appropriate programs to promote healthy behavior by adolescents and adults. It examines the problem of fragmentation in STD services and provides examples of communities that have formed partnerships between stakeholders to develop integrated approaches. The committee's recommendations provide a practical foundation on which to build an integrated national program to help young people and adults develop habits of healthy sexuality. The Hidden Epidemic was written for both health care professionals and people without a medical background and will be indispensable to anyone concerned about preventing and controlling STDs.
