Humanised Organs Can Be Grown In Animals :: Stem Cell Research Biology Science Essays

Humanised Organs Can Be Grown In Animals Ever since stem cell research has been discovered there have been many controversial arguments discussing whether or not this method is okay to use when dealing with patients. Research on stem cells is advancing knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. Since it was discovered, stem cell research is coming a very long way, even though these processes probably won’t be experimented in humans years for decades. Right now in stem cell research we are extracting stem cells from humans bone marrow and inserting them into animal fetus's before the immune system can learn the difference between it's own cells and foreign cells. The plan is to grow more human stem cells in animal organs than animal cells so we can perform organ transplants to replace damaged organs with the animal's organs. The only problem about this, is a rejection of the animal portion of cells in the human body. This means that the cells in our body could attack this new organ. Although, this therapy is still years away, the beginning processes have been started by a team led by Esmail Zanjani at the University of Nevada. Zanjani’s team hopes that the animal-human organs they are working on will have compatible new cells that are exactly the same as a patient’s organs for fixing damaged organs. With the new research they have found, it could be possible that they replace whole organs. The only problem about animal-human organs is that people could get viruses from animals that humans don’t normally acquire The original plan of Zanjani’s was to see prevent birth defects in unborn babies by injecting healthy stem cells into the fetus but in the process of doing this, he found that in doing this process, it could also be used to grow â€Å"humanized† organs. This idea came from the work of Flake. He found that the human cells develop into part of the heart, skin, muscle, fat, and other tissues when stem cells are taken out of bone marrow and injected into sheep fetuses. Stem cells have two important characteristics that distinguish them from other types of cells. First, they are unspecialized cells that renew themselves for long periods through cell division. The second is that under certain physiologic or experimental conditions, they can be induced to become cells with special functions such as the beating cells of the heart muscle or the insulin-producing cells of the pancreas.

European Disease in the New World Essay -- American America History

European Disease in the New World Humans possess an innate curiosity that drives us to explore the unknown. Documentation of exploration by sea goes as far back as 3200 B.C., when Pharaoh Snefru brought 40 ships from Byblus to Phoenicia, followed by the first recorded expedition of exploration from Egypt in 2750 B.C, (http://www.mariner.org/age/histexp.html). Events such as these would eventually give way to a period of vigorous exploration known as the Age of Exploration. At the height of the Age of Exploration in the early fifteenth century, European nations became poised to expand their influence to the rest of the world. Due to their remarkable programs of sustained and systematic exploration, they were well equipped for countless expeditions driven by the desire for fortune and conquest, often disguised by a religious agenda. What resulted in their efforts, however, was not the enlightenment of a people, but rather, the transformation, and in some cases, the destruction of the cultures that these Europeans "disc overed." They brought more than materials, technologies, and i...

The Ethics of the Mental Pursuit of Perfection Essay -- Exploratory Es

Introduction    The number of individuals diagnosed for one or more mental disorders and consequently treated with a corresponding drug has significantly increased the past several years. The following statistics displaying this are shocking: * 8.5 million people are prescribed Effexor, an anti-depressant every year (Harris, 2004). * More than 1 million children and teenagers are taking drugs for some form of mental disorder (Elias, 2004). * There are close to 2 million cases each year of drug complications that result in 180,000 deaths or life-threatening illnesses in the eldery (Langreth, 2004). These alarming figures call us to question the causes behind this influx of diagnosed mental disorders as well as the consequential drug prescription as a solution. When asked to discuss the ethics of the mental pursuit of perfection, there are several different aspects to consider. The main ethical issues raised lie in the prescription of drugs to children and the over prescription of drugs. In addition, I will discuss who and what are responsible for our culture’s desire to â€Å"quick fix† every definable problem with some type of drug, be it prescribed, non-prescribed, or self-prescribed.       Mental Disorders in Children When one thinks about mental disorders in respect to children, Attention Deficit Hyperactivity Disorder (ADHD) immediately comes to mind. Defined now as â€Å"children who are excessively active, are unable to sustain their attention, and are deficient in their impulse control to a degree that is deviant for their developmental level† (Loewenton, 2002), ADHD now affects up to 5% of schoolchildren and continues in roughly 60% of those youths as they age (Henderson, 2004).

The Problem with Oliver by Maggie O’Farrell

Most teenagers have experienced that odd moment when their parents know what they are doing, even though they haven’t told them; and they certainly don’t like being compared to their parents. Young people consider themselves as individuals who have nothing in common with their parents – but in fact they might have more in common with their elders than they think. The latter might be the case for the main character in Maggie O’Farrell’s short story â€Å"The Problem with Oliver†, Fionnuala, who is a perfect, and almost stereotypical, example of a teenager of the kind mentioned in the sentences above.This short story covers some of the greatest problems and themes, we are all likely to encounter in our own life somehow. It is about the relationship between mother and daughter and about social heritage, how we all deal with growing up, falling in love – which is most likely to be kept secret by young people. What to do, when the one youâ €™re in love with comes from a culture that is despised by your closest family. When the mother is experiencing her first out-of-body experience and tells Fionnuala about it, Fionnuala is rather sceptical and is wondering if her mother has been smoking.She makes it clear to herself, that her mother has officially gone mad, and she is frustrated and tries to erase the possible similarities between Fionnuala and her mother. They don’t even look alike – not anymore. Not since Fionnuala has started straightening her hair. In which, you could say that Fionnuala will most likely not want to look like her â€Å"mad† mother. But the out of body experience made Grainne wonder if her daughter was going to make the same mistake by bringing Oliver along to the beach hut. She is laughing, probably trying to laugh it off and make Fionnuala understand it.She then says: â€Å"Then I realised it was you, and I was me, in here, in the house. † (l. 71) In which could me an that Grainne is willing to let her daughter manage it in her own way. Fionnuala may not repeat the mistake, because she could differ so much from Grainne. Fionnuala has an English boyfriend, Oliver. The mother haven’t heard about their relationship from Fionnuala, and Fionnuala is afraid of letting her know, because of her disliking of English men as equal to weak tea and amoebic dysentery (l. 49). The mother is exceedingly fond of Irish folklore and treasures the ancient traditions.And her fondness is clearly expressed in the name she has given her daughter; the name Fionnuala was, according to Fionnuala herself, an ancient Irish princess who turned into a swan. But it is obvious that Fionnuala is ashamed of her mother’s eccentric behaviour; when she first met Oliver, she introduced herself as â€Å"Finn†, unable to add the two last syllables in her name out of sheer embarrassment. The episode, where Fionnuala’s mother Grainne hides the key to the bea ch hut from her daughter, could very well be the result of a bad experience from Grainne’s younger years.We know from the text that Grainne moved to England to escape the fury of her family, and since Grainne is able to hide away the key to the beach hut, it could be a sign of her trying to avoid repeating the episode. This looks very much alike the episode, where Grainne sits on a bench and she spots a cat that is about to make it a run for the crumb-pecking finch. (ll. 25-33) Grainne is preventing the cat from getting to the bird by throwing a cloth towards a window.In the same way, she is attempting to scare Fionnuala or teach her a lesson, and maybe save her from something that could go wrong, like it did for Grainne, when she was younger. So Grainne knows, that there is something bothering Fionnuala, maybe that she haven’t done it yet, and almost the rest of the school has. In the text, Grainne warns Fionnuala about not giving in for peer pressure, and that would save a lot of trouble later. Right when Fionnuala had cancelled the date with Oliver and gone terribly mad at her mother, she founds the key on her bed, and her mother is gone.Grainne would maybe rather run away herself than run the risks of getting furious with Fionnuala’s boyfriend, so Fionnuala did not have to run anywhere. By growing up, your sense of realism is developing, the older you get. So as the dark, twisted branches of the hawthorn tree tap-tap against the side of the house, as if wanting to come in, could be referred to as the reality, wanting to come inside the house – her mind. Grainne knows what is going on, and therefore, things may get easier for Fionnuala in the future. She could maybe be torn between her mothers strong Irish standards and her boyfriends English ways.

Mine and My Parents’ Attitude on Life Essay

altogether of my keep, my p bents are the great shoulders for me to lean on. They piece the happiness with me, comfort me whenever I am sad, they are the muckle who al tracks over use up me e truly conviction I fall. However, , my parents and I do non pack the analogous military position toward my studying, my human relationship and coin. The contrast in our attitude depicts our life, to a greater extent or less, complicated but interesting.First, my parents and I adjudge different ideas about studying in the college. From the start, for my parents attitude, studying in the college factor only books and grades. They verbalize to me as I was a freshman, When you receives your degree, we want you to be fitted to get a traffic that forget support yourself. We in any case want you to brook grades that will make you a existent candidate for that job. Dont make college life a waste of prison term. It means I will miss just about of my cartridge holder in the libra ry, att wipeout to all the lectures hours, study hard solar day meter by day and at the pole of the semester, I will have to get word them my high grades. Following their advices, I do non have free prison term for myself, I cant take part in any surplus -curriculums such as sports, art and writings activities or even a depressed birthday party held in the dorm.My parents environ such things above the useless-and- waste-of time. extravagance of time and useless? Not on my life. How can I waste time with so many new ideas to get word and all the interesting and open-minded people to meet in these activities? How can culture to see the world in a different way and leaving college with a new outlook on life be a waste of time and useless?. In contrast to my parents, books and grades are non enough, I need more(prenominal) activeness and practical things for my studying.My parents and I also differ in the attitude toward the relationship surrounded by my opposite- e nergize friends and I. I have many friends, boys and girl, in high school, in the university, even at the shop where I have a part-time job. However, I find it easier to have the opposite sex ones as my close friends. They are easy-going, unsophisticated and less talkative than girls. I do think that we are only friends, that on that point is naught unusual in our intimacy moreover, my friends, as well as me, are old enough to know the demarcation between bonk and friendly relationship. On the otherwise hand, my parents do not share the same point of view with me. They always guess that there is no intimacy between boys and girls. They consider our friendship as love and violently show their disagreement whenever we watch this matter. These loves will give bad effects on your studying and lead you to nowhere, my dear., said my mother times and times again. No matter how hard I try to explain, they still keep their attitude, advising me to put an end to such loves-which ar e actually the friendship that boys and girls can have.The contrast that we have do not end with attitudes toward my studying and friendship but also toward capital and the way to spend it. My parents have healthy attitude toward gold they consider money as a tool, as something they have, not something they are. workings hard day by day to support the family, they spend every penny of every dollar of the money they realise economically and reasonably. A fool with his money will soon parted, my render always reminds me. We spend much money on neither clothes, delicious feed , nor presents for birthdays and holidays. My parents save money and never put forward the saving in the bank if it is not necessary. Thanks to this, my sister and I could go to university without worrying about financial problem.Compared with my parents, I used to have quite minus attitude toward money. There was a time when I thought money was the most important factor in my life, money could buy me anyt hing I want happiness, friendship and other peoples admiration. I wasted all my money on fashion, expensive jewels, presents for my friendsetc. Unfortunately the profit I got from my part time job could not afford, as a result, I was stuck in debt at a very young age 18. There were nothing left for me no friends, no happiness, no respect, but the sadness in my family. repayable to this unforgettable lesson, I can not disclaim that my parents point of view is decidedly right.Though the contrast in attitudes toward such things as my studying, my friendship, and the way to use money is the reason why sometimes we purport upset and even sulk, it do not cause the generation gap in my family. My parents are not always right, so am I. But we know that if we have more chances to exchange our ideas, we can pull in each other well and makes our space a really happy family.

Prejudice, Stereotyping, and Discrimination Essay

Women and men use stereotypes to create sense of the planet.† (Feenstra, 6. 1 Prejudice, stereotypes, logical and discrimination, para 1). Prejudice is a negative belief or feeling (attitude) about a particular group of individuals. Prejudices can be passed on from one generation to the next.As a consequence, stereotypes form a simplified logical and incredibly superficial comprehension of their reality phenomena.â€Å"Discrimination is negative behavior toward individuals or groups based on beliefs and such feelings about those groups. A group you are a part of is called your ingroup. Ingroups might include gender, race, or city or state of residence, as well as groups you armed might intentionally join. A group you are not a part of is called your outgroup.

There are just twenty two minor kinds of discrimination.The world was a changing place; many times, we saw and heard prejudice, stereotyping, and discrimination at its worst. Unfortunately, we are seeing the same types of prejudices, stereotyping, and discrimination going on today; especially since the â€Å"9-11† attacks and with the â€Å"Occupy or 99%† movement going on today. Social identities depend on the groups to which people belong.Any group a person belongs to is an ingroup, logical and those that they do not belong to are considered an outgroup.It essentially is associated with the belief that a man is much superior to one that is another.And outgroup homogeneity bias blinds us to the differences within the outgroup. † (Feenstra, 6. 1 Social Cognitive origins of prejudice and stereotypes, para 2). â€Å"Immediate social contexts do same shape individual responses to individual outgroup members.

Prejudice doesnt rely with people.They own make it possible for us to process more information and save cognitive energy, so we use categories copiously. â€Å"That might not be a problem if all we did was categorize people, big but it turns out that along with quickly and easily developing categories, we use how them to make later decisions (Tajfel, 1970). † (Feenstra, 2011, 6. 2 Categorization, para.It contributes to discrimination.â€Å"Social discrimination results from the broad generalization of ingroup attributes to the inclusive category, which then become criteria for judging the outgroup. Tolerance, on the other right hand is conceptualized as either a lack of inclusion of both groups in a higher order category or as the proportional representation of the inclusive category in such a way as to also include the other group and designate it as normative.† (Mummendey & Wenzel, 1999, P. 158).

It could be spread by the use of propaganda.d. , P. 10). Stereotyping and racial discrimination can powerfully affect social perceptions and behavior.Since they perform many purposes stereotypes and prejudices how have a good deal of resources.d. , P. 19).Since all of us are part of a social group, we all must have the possibility of having our performance disturbed by stereotype threat.

Competition for funds may additionally fresh produce bias.d. , P. 11). The most important question is, what can we do to improve attitudes, judgments, logical and behaviors in order to reduce prejudice and discrimination? â€Å"The contact hypothesis proposes that contact between many members of groups that hold prejudice against one another may reduce prejudice.Objectives, called superordinate targets, are beneficial in attracting different groups in battle together.Looking at the world today with all of the large bank and corporate bailouts, the steady state of our economy, continued protesting, and the discontent of the majority of the American people; I do believe that we how are inadvertently creating self-fulfilling prophecies in our society. In Self-Fulfilling Prophecies, Michael Biggs states, â€Å"A theory of american society could, in principle, prove self-fulfilling.Marxism predicts that capitalism is fated to end in revolution; if many people believe in the theory , then they could forment revolution (Biggs, 2009). † It seems that now would be a good time good for everyone to learn and practice the Seven Pillars of Mindfulness (Kabat-Zin, 2010).
