Deactivation of Prions in the Healthcare Setting Prions are infectious agents composed entirely of a protein material which is transmissible to other prion proteins leading to disease in a manner that is epidemiologically comparable to the spread of viral infection. Prions composed of the prion protein are believed to be the cause of transmissible spongiform encephalopathies among other diseases. All known prion diseases are untreatable and fatal. . Prions, however, are infectious by their effect
whether they truly understand nature's ground rules. That's exactly what prions have done to scientists' understanding of the ground rules for infectiousdiseases. Prions cause diseases,but they aren't viruses or bacteria or fungi or parasites. They are simply proteins, and proteins were never thought to be infectious on their own. Organisms are infectious, proteins are not. Or, at least, they never used to be. Prions entered the public's consciousness during the mad cow epidemic that hitEngland
Prions Prions have been a mistery for scientists from the day they where discovered. Prions act like viruses but they are not. Their structure and chemistry are unknown. They are believed to be proteins but that is yet to be completely proved. Prion stands for “proteinaceous infectious particles”. Prions are known to cause many diseases involved with nervous systems like the brain. They are the ones that cause the well known “ mad cow
Prion Diseases Abstract Transmissible spongiform encephalopathies (TSEs) are neurodegenerative diseases that are thought to be caused by the misfolding of prion proteins. Prions are able to replicate in the absence of nucleic acids. TSEs include: scrapie, bovine spongiform encephalopathy, Creutzfeldt-Jakob disease, kuru, Gerstmann-Straussler-Scheinker disease, and Fatal Familial Insomnia. They can affect many different animals, including humans. Currently, there are no ways to diagnose, treat
Proteinacious Killer Abstract: Prions are proteins (PrP) that usually reside in the brain. There are two different forms of prions: normal PrPC and the pathological isoform, PrPSc. The two forms are chemically similar but shaped, or folded differently. PrPC occurs naturally in most mammals but PrPSc seems to bring with it various diseases, or spongiform encephalopathies. Various forms of these diseases have been found in many animal species, including humans. The actual means by which PrPSc propagates
encephalopathies that affect a wide range of animals, BSE has received the most attention because many people in the world consume beef and people are that they might contract the disease from eating a burger at their favourite fast-food restaurant. In this essay I will discuss BSE and other forms of Spongiform encephalopathies, how it affects the ani mal, what causes the animals to contract the disease, and the recent issues of BSE in the world. I hope to set out the true facts about BSE and that it only affects

Meeshali Patel Mr. Brennan AP Psychology 19 August 2012 AP Psychology Essay How essential is memory to us? Why is this term highly verifying to people in the world? Memory is a being’s power to remember things and retain information from the past. Human beings are encountered by this process of remembrance for eternity- throughout their lifetime. It is a key element for an individual, which doesn’t have an authentic origin. Memories can be portrayed in many unique ways, such as emotionally
purpose of this essay is to understand over representation as it exists in the contemporary criminal justice system. Particular emphasise will be placed on the levels of women and youths in the criminal justice system, their contact with the system and empirically based risk factors pertaining to over representation. An evaluation of alternative programs in the pre and post sentencing stage and the impact such programs would have on the over representation will be conducted. This essay aims to lookat
chronic diseases. The western diet, he argues, is not good and should be put to an end. As Pollan asserts, people should focus more on eating well balanced meals, rather than putting their health at risk with an unhealthy diet. A key point in Pollan’s essay is that the food industry and the health industry play a major part in the western diet. He argues that the theories of these scientists contradict each other and most of the blame should go to them. He also argues that the food industry releases new
