Mad Cow Disease
Bovine spongiform encephalopathy (BSE), better know as Mad cow disease is a relatively new disease. Most sources state that BSE first showed up in Great
Britain in 1986 [Dealler p.5] but some say it popped up in 1985 [Greger p.1].
However the official notification was not until 21 June, 1988 [Dealler stats.
p.1]. Spongiform encephalopathies are invariable fatal neurodegenerative diseases and there is no treatment nor is there a cure for this disease [Greger
p.1]. The recent scare of BSE has arisen because of the contraction of
Creutzfeldt-Jakob disease (CJD: see Appendix B) in humans from eating beef products. Although there are many forms of Spongiform 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 a small percent of the world population. Due to the fact BSE is a new disease most of my information might be proven wrong in the future because there is a great deal of testing going on in the scientific community. They are also very concerned about this new disease and the effects it can have on humans if it is not stopped.
Bovine spongiform encephalopathy is not some bacteria and it is not a virus, but in fact it is an infectious protein or prion [Greger p.2]. Before I go into more detail, I would like to discuss what a prion is. A prion is composed solely of proteins, and lacks genetic material in the form of nucleic acids. They are the tiniest infectious agents known, they can only be viewed under the strongest of electron microscopes [see appendix A]. Most scientists are puzzled because nucleic acid is the basis reproductive material needed in all other life forms
[Britannica vol.9 p. 978]. Because of their unique makeup, prions are practically invulnerable. They can survive for years in the soil. Chemical disinfectants, weak acids, DNAase, RNAase, proteinases [Dealler p.8], ultraviolet light, ionising radiation, heat, formaldehyde sterilization, and chemicals that react with...

Dr. Nagami detailed many diseases in this book all of them life threatening in some way. Some were obscure while some were unfortunately common. I know that I will not look at chicken pox as being a simple childhood disease again. The impact
In Bladerunner the most prominent element of cinematography is mise en scéne. It generates a context for the film and therefore makes the plot and themes acceptable. To set an appropriate scene different variables need to be controlled. These variables include location, props, lighting and colour. In general the location of the plot is in the vast urban canyons of 2019 LA. The imposing dark buildings, the dirty fog, perpetual rain and the crowded dark streets devoid of vegetation make up the backdrop of most scenes. All this is filmed in dark lighting, which complements the effect produced by the fog in obscuring the living details. From this the responder acknowledges the deterioration of society, the harsh conditions that the humans are subjected to and the way the human spirit itself is progressively destroyed under such conditions.
Blade Runner, which is directed by Ridley Scott and is based on Philip K. Dick's novel Do Androids Dream of Electric Sheep, is a Sci-fi Noir film about a policeman named Rick Deckard (played by Harrison Ford) in 2019 Los Angeles who was contracted to retire four genetically engineered replicants. The four fugitives, Pris (played by Daryl Hannah), Zhora (played by Joanna Cassidy), Leon (played by Brion James), where led by Roy Batty (played by Rutger Hauer) and have escaped from an off-world colony in order to find their creator and oblige him into expanding their pre-determined four year life span. A part of the success that this feature has received can be attributed to the film’s ability to operate on many different levels.

The novel The Awakening is written by Kate Chopin in 1899 which shocked the readers with its honest treatment of female infidelity. Edna Pontellier is a married woman that is trapped in a stifling marriage. She then seeks to find the love and freedom that she desires with Robert Lebrun and Alcee Arobin. She broke her role of an ideal “mother woman” in her society and discover her true identity as being independent and passionate about what she desires.
A fundamental element of any childhood is watching a classic Disney movie on the couch and singing along to the catchy musical numbers while simultaneously falling in love with the characters. What many people do not know, is that most Disney movies are adaptations of classic fairytales. One of Disney’s most famous movies, The Little Mermaid, is an adaption of a fairytale written by dutch writer Hans Christian Andersen in 1876, Den lille havfrue. While the two texts share a title, they differ in multiple key elements throughout the story.
...animal feed. These high risk substances come from the brains and spinal cords of cattle that are at least 30 months of age or older. Since the feed ban in 1988 the amount of reported cases has significantly dropped. In 1998, it came down to 1,567 reported cases. Last year, 4,454 new cases had been reported, compared to 37,301 new cases at the peak of the BSE disease in 1992. BSE can eventually be eradicated if there is no other significant source of infection (6).
An experience becomes traumatic when one suppresses themselves to the truth. In The Nirvana Principle by Lisa Bird-Wilson, each time the imagery of a girl at the ravine is repeated throughout the story, the narrator exhibits progress with her healing process. The narrator is an intelligent yet stubborn 14 year old girl named Hanna. The story takes place in the room of the narrator’s shrink, Dr. Semenchuk. Throughout the short story, Hanna undergoes a healing process she is trying to work towards due to a trauma that she has encountered. Yet even with the help of her doctor, she struggles to be at peace with herself and the world around her. The narrator uses self-therapy when describing this particular recurring image of a body in the river
It is believed that this virus has been in hiding since ancient times. The lack of knowledge about it’s natural history and reservoirs keeps researchers seeking out the mysterious virus that has no treatment or cure. Based on the available evidence and comparisons of similar viruses, researchers believed the virus to be animal-borne and that the host animal is native to Africa. Their attempts have been unsuccessful, and the source of the virus or where it circulates in between outbreaks is unknown.
The purpose of this paper is to focus on a subject within my educational field that I can research and inform the public about. I plan to become a veterinarian .which would require my daily contact with humans and animals. Zoonotic diseases are risk factors that I have to be aware of in order to protect myself as well as my patients and their owners. Luckily developments in medicine have made it possible to cure zoonotic diseases and even prevent them from ever being contracted.
An abundance of Americans have no idea that most of the food that they consume are either processed or altered in one way or another. “Almost all beef cattle entering feedlots in the United States are given hormone implants to promote faster growth. The first product used for this purpose is DES (diethylstilbestrol) it was approved for use in beef cattle in 1954. An estimated two-thirds of the nation's beef cattle were treated with DES in 1956. (Swan, Liu, Overstreet, Brazil, and Skakkebaek)” Many people enjoy the various meats that comes from a cow, but that would probably change if the consumers knew that cattle is one of the most processed meat source in the market today because of the synthetic hormones that the cows are given. “ The three synthetic hormones are the estrogen compound zeranol, the androgen trenbolone acetate, and progestin melengestrol acetate. (Swan, Liu, Overstreet, B...
A key theme in Blade Runner is that it portrays postmodernism throughout the movie by blurring the differences of the real and the artificial, in the film there is a scene where Rick is questioning Leon to see if he can provoke emotions to determine if he is a replicant or a human which showed that no one really has a clear understanding of what is real. Blade Runner also touches on the theme of time-space compression not only by the presence of flying cars which diminishes the time that it takes to get anywhere making information and travel so much faster but also by making the lifespan of the replicants only four years makes time less relevant because of the amount of living they have to do in a fifth of the life of a human. The theme of creative destruction is also shown in a scene where they are explaining what the blade runner is and how his job is to catch and “retire” the replicants because they have started to rebel and they need to make sure they don’t become too
Is Blade Runner purposefully presenting a future that excludes minorities? The obvious is no, meaning is constructed by the viewers as the director can only do his or her best to conduct a fluid projection of their story. In this case, Scott created a masterful depiction of a post-modern, neo-noir-esque world in which we as humans co-exist with androids. Although the meaning of Blade Runner is up for interpretation, the argument of racial identity and the lack of people of color still remains. While minority culture is displayed through the vast signage and advertisement on the buildings of Los Angeles, and the short screen-time of the casual bystander being African-American or of Asian descent, bad representation is not representation. Are people of color not capable of existing/surviving in the world of Blade Runner? For all of the attention to be put towards the intricacies of the details and plot of the film, the two-hour film does very little to concern itself with anything beyond the depth of the white male protagonists which ultimately sidelines non-white characters. Instead, the film generates the ideologies perpetuated by American history and has now written the future. While the true meaning of racial absence in the film is never mentioned, it preserves the idea of racial hierarchy.
Cows are naturally very gentle and calm creatures. These smart and sweet natured animals have been known to go to great lengths to escape slaughterhouses. More than forty-one million of these sensitive animals suffer and die a painful death each year in the United States. When cows are still very young they are burned with hot irons, there testicles are torn or cut off, all without painkillers. Most beef cattle are born in one state, live in another, and are slaughtered in another. The cows who survive the gruesome transportation process are shot in the head with a bolt gun, hung upside down by there legs, and taken onto the killing floor where there throats
