| viruses worksheet answer key: Retroviruses John M. Coffin, Stephen H. Hughes, Harold Varmus, 1997 For over 25 years the study of retroviruses has underpinned much of what is known about information transfer in cells and the genetic and biochemical mechanisms that underlie cell growth and cancer induction. Emergent diseases such as AIDS and adult T-cell lymphoma have widened even further the community of investigators directly concerned with retroviruses, a development that has highlighted the need for an integrated understanding of their biology and their unique association with host genomes. This remarkable volume satisfies that need. Written by a group of the field's most distinguished investigators, rigorously edited to provide a seamless narrative, and elegantly designed for clarity and readability, this book is an instant classic that demands attention from scientists and physicians studying retroviruses and the disorders in which they play a role. |

| viruses worksheet answer key: Potential Risks and Benefits of Gain-of-Function Research National Research Council, Institute of Medicine, Board on Health Sciences Policy, Policy and Global Affairs, Committee on Science, Technology, and Law, Division on Earth and Life Studies, Board on Life Sciences, 2015-04-13 On October 17, 2014, spurred by incidents at U.S. government laboratories that raised serious biosafety concerns, the United States government launched a one-year deliberative process to address the continuing controversy surrounding so-called gain-of-function (GOF) research on respiratory pathogens with pandemic potential. The gain of function controversy began in late 2011 with the question of whether to publish the results of two experiments involving H5N1 avian influenza and continued to focus on certain research with highly pathogenic avian influenza over the next three years. The heart of the U.S. process is an evaluation of the potential risks and benefits of certain types of GOF experiments with influenza, SARS, and MERS viruses that would inform the development and adoption of a new U.S. Government policy governing the funding and conduct of GOF research. Potential Risks and Benefits of Gain-of-Function Research is the summary of a two-day public symposia on GOF research. Convened in December 2014 by the Institute of Medicine and the National Research Council, the main focus of this event was to discuss principles important for, and key considerations in, the design of risk and benefit assessments of GOF research. Participants examined the underlying scientific and technical questions that are the source of current discussion and debate over GOF research involving pathogens with pandemic potential. This report is a record of the presentations and discussion of the meeting. |

| viruses worksheet answer key: HIV and the Blood Supply Institute of Medicine, Committee to Study HIV Transmission Through Blood and Blood Products, 1995-10-05 During the early years of the AIDS epidemic, thousands of Americans became infected with HIV through the nation's blood supply. Because little reliable information existed at the time AIDS first began showing up in hemophiliacs and in others who had received transfusions, experts disagreed about whether blood and blood products could transmit the disease. During this period of great uncertainty, decision-making regarding the blood supply became increasingly difficult and fraught with risk. This volume provides a balanced inquiry into the blood safety controversy, which involves private sexual practices, personal tragedy for the victims of HIV/AIDS, and public confidence in America's blood services system. The book focuses on critical decisions as information about the danger to the blood supply emerged. The committee draws conclusions about what was doneâ€and recommends what should be done to produce better outcomes in the face of future threats to blood safety. The committee frames its analysis around four critical area: Product treatmentâ€Could effective methods for inactivating HIV in blood have been introduced sooner? Donor screening and referralâ€including a review of screening to exlude high-risk individuals. Regulations and recall of contaminated bloodâ€analyzing decisions by federal agencies and the private sector. Risk communicationâ€examining whether infections could have been averted by better communication of the risks. |

| viruses worksheet answer key: Caring for People who Sniff Petrol Or Other Volatile Substances National Health and Medical Research Council (Australia), 2011 These guidelines provide recommendations that outline the critical aspects of infection prevention and control. The recommendations were developed using the best available evidence and consensus methods by the Infection Control Steering Committee. They have been prioritised as key areas to prevent and control infection in a healthcare facility. It is recognised that the level of risk may differ according to the different types of facility and therefore some recommendations should be justified by risk assessment. When implementing these recommendations all healthcare facilities need to consider the risk of transmission of infection and implement according to their specific setting and circumstances. |
