    ... her factors include abnormalities in the proteins that regulate blood cell production and a malfunctioning immune system that interferes with the normal blood cell production. Certain environmental factors have been associated with the development of plastic anemia. Chemotherapy drugs such as busulfan or antibiotics such as chloraphenicol can cause temporary or prolonged plastic anemia. Chemicals such as benzene and pesticides, infections such as viral hepatitis and mononucleosis, autoimmune disorders and ionizing radiation also has been linked to the development of plastic anemia. Although exposure to these agents increases the risk of developing plastic anemia, it is proven that they a ...

    Cloning Cloning Twenty-five years ago, scientists thought that cloning was virtually impossible. In the last five years, the science of cloning, has come to realization. What is a clone? A clone is a duplicate - much like a photocopy is a duplicate, or copy, of a document (Kolate, 238). A good example of copies that occur in nature are identical twins, which are duplicates of each other. On a daily basis, molecular geneticists and other scientists use cloning techniques to replicate various genetic materials such as gene segments and cells (Kolate, 238). Recently the cloning of a living life form was brought from the realms of science fiction to reality with the cloning of a sheep named Doll ...

    Cloning Nicole Pluta November 29, 1998 Scientific experimentation has led us to many great discoveries such as: Chemotherapy, heart surgery, and bone marrow transplants. Recently scientists have discovered a new way to heal humans. This is known as cloning. Although they have yet to clone a human they have cloned sheep. Cloning has brought up a huge controversy among the American people. There are two sides to the story. Either you agree with cloning or you dont. The only way to help make that decision is to look at the good and bad points of cloning. There are many positive aspects of human and non-human cloning. Human cloning technology could be used to reverse the number one killer in the ...

    Cloning Cloning: Recently, we have all seen the controversy over whether or not we should attempt to clone. If you haven't heard: A group of scientists in Scotland announced the birth of a sheep cloned from embryonic cells, presaging Dolly. Dolly's was the birth heard round the world. The first mammal ever cloned from a single adult cell, she was living proof that scientists had solved one of the most challenging problems of cell biology. Her creation raised a troubling question: Can humans, too, be cloned? And if so, Should humans be able to play God? Cloning has been an idea that the world has awaited and feared for decades. Cloning has been around since the 1950s when 2 scientists made a ...

  • Cloning - 918 words
    Cloning Cloning In the past few years, the topic of cloning has been in the news a lot. It is a very controversial issue, with many opposing viewpoints. While some find it acceptable, others object for religious reasons. A big concern is the possibility of abuse of this new technology. One of the big questions is Where will we stop? We may start by just experimenting and studying, but then what? Manufacturing human bodies for spare parts? No one can be sure where it will stop. The Supreme court says that everyone has the right to make their own reproductive decisions without government interference, but now it is proposing bans on human cloning. These bans prevent the very research needed to ...

    Cloning And Ethics Ever since the successful cloning of an adult sheep, world has been buzzing about the historical event. "Dolly" the sheep has redefined the meaning of the words "identical twin." Not only does she look like her mother, she has the same genetic makeup as her. This experiment was not only was thought of as impossible, but unthinkable. It was achieved in July 1996 by Dr. Ian Wilmut of the Roslin Institute in Roslin, Scotland. "Dolly" was announced to the public when she was seven-months old, on February 23, 1997. Since the birth of "Dolly," the Wilmuts Institute has cloned seven more sheep from three different breeds. This process that successfully worked with the sheep, is n ...

    Cloning Benefits Cloning Benefits What if while walking down the street you encountered someone who looked exactly like you? Would you stare in amazement or would your heart be filled with fear? At first some people may look upon the idea of cloning with disgust and question themselves if humans should play God while others would be interested and study the many possibilities that cloning offers. This illustrates the path that cloning has taken over the latter part of the twentieth century. At first, when cloning was brought up in conversations, people tended to fearfully think of an army of identical persons marching across the earth in hopes of ruling humans. This and many other absurd not ...

    ... the unfertilized egg from sheep B. The egg, now with a full complement of genes, began dividing and was placed into the uterus of a surrogate mother (sheep C). The embryo developed normally and was delivered safely. Named Dolly, this healthy sheep was introduced to the world with much fanfare in February 1997 (Encarta, 06). While Dolly has most of the genetic characteristics of sheep A, she is not a true clone. Not all of an animals genes are found in the cells nucleus. There are a few dozen genes that reside in the mitochondria outside the nucleus in the cells cytoplasm. In Dollys case, some of these genes were supplied by the donor egg of sheep B (Encarta, 06).

  • Cloning Issue - 1,285 words
    Cloning Issue Genesis 11:1-9 records the sad story of the building of the tower of Babel. That project stands out as the first chapter in a story that continues to this day, and includes many similar kind of undertakings. As technology and ability increase so does man's ability to do things that are ultimately not in his best interest. The first objection is that cloning is not wise. Wisdom is knowing the end of a matter from the beginning. Proverbs 14:15 tells us "The naive believes everything, But the sensible man considers his steps." It is sensible or prudent to think carefully about the path we are walking, and where it will lead us. Proverbs 22:3 reminds us "A prudent man foresees evil ...

  • Cloning Morality - 648 words
    Cloning Morality Currently with technology advancing rapidly in every aspect of life, is it possible that humans can recreate themselves. This big ethical and moral question is on the minds of almost every person in the world. Should we as a human race make duplicates of ourselves? There are several things to look at and to consider when making decisions based on God like proportions. There are health risks from mutation of genes. An abnormal baby would be a nightmare come true. The emotional risks could have a deep impact. For instance, the child grows up knowing her mother is her sister, her grandmother is her mother. Every time her mother looks at her, she is seeing herself growing up. Th ...

  • Cloning Process - 1,220 words
    Cloning Process Cloning, the process of creating a copy of a plant or animal that is genetically identical to the original through asexual means, has sparked some interesting moral and ethical debate. For years, cloning has been used to produce a greater number of a specific type of plant, such as the Macintosh apple trees, which have all been derived from single mutated plant . Now, however, upon the discovery of a method to clone animals, even humans, people are beginning to become aware of the benefits and consequences of cloning, as well as the ethics involved. Cloning has had a fairly long history. In 1952, the first successful cloning experiment took place. Scientists Robert Briggs and ...

    ... encies often favor these projects (MFAT). Mankind has a tendency to seek out the fastest and easiest way to devise an answer, usually for the cheapest cost. Sadly, it seems animals may not be entirely saved from this tendency soon enough. Global Awareness - While animals continue to be violated in laboratories, a consciousness about our responsibility toward our relationship with animals has begun and continued to rise. As a result of pressures from animal advocacy groups such as PETA (People for the Ethical Treatment of Animals), a number of large corporations have ceased all animal testing in recent years. These corporations include Avon, Amway, Benetton, Revlon and even General Motors ...

  • Erythropoietin Essay - 1,034 words
    Erythropoietin Essay Introduction. Erythropoietin is a glycoprotein that is produced primarily in the kidneys in adults and, to a lesser extent, in the liver. It behaves like a hormone, regulating the level of erythropoiesis, and keeping the RBC count within a narrow range It is used widely in medicine as a treatment for a number of serious illnesses, ranging from types of anaemia, to the treatment of certain types of cancer, and also in the battle against AIDS. Unfortunately certain athletes, who will do anything to win, have realised its ergogenic benefits, and also the severity of its misuse. Regulation of Erythropoietin Production. In the kidneys, erythropoietin is produced in fibroblast ...

  • Ethics Of Embryonic Cloning - 1,341 words
    Ethics of Embryonic Cloning Embryonic Wars The specific objective of this major essay is to clarify and summarise the controversial debate concerning the ethical decency of embryonic cloning for therapeutic purposes. This is the form of cloning that is supposedly beneficial to a barrage of medical applications. We will identify the key opposing ethical perspectives such as those of the justification of embryonic research based on the normative theory of consequentialism. This paper will also probe into the relatively brief history of the debate while gauging the particular stumbling blocks of disagreement which bioethicists have arrived at. The topical aspects of therapeutic cloning will be ...

  • Euthanasia Mercy Killing - 1,039 words
    Euthanasia Mercy Killing Sue Rodriguez has reminded us all of our own mortality and our need to think carefully about the kind of society we want to live and to die in. Sue Rodriguez was known through the media, and her well spoken and eloquent speeches. People painfully in support of what she believed in, watched as her strength was sapped by the devastating disease (amyotrophic lateral sclerosis), and we were moved by her clear thought and her bravery as a person facing death. Here was a woman who acted on her beliefs with courage and tenacity and whose grace has enriched us all. It is no defense to point to the fact that a person has requested to be killed: "No person is entitled to conse ...

  • Even In Her Earlier Poems, Sylvia Plath Displays An Unhealthy Preoccupation With Sex, Madness, Morbidity And Obscurity - 993 words
    Even in her earlier poems, Sylvia Plath displays an unhealthy preoccupation with sex, madness, morbidity and obscurity. Discuss. There seem to be a number of common themes running through all of Plaths poems, which encapsulate her personal attitudes and feelings of life at the time she wrote them. Of these themes, the most prevalent are: sex, madness, morbidity and obscurity. The whole concept of sex to Plath appears to be a very disturbed and resentful one. This is conveyed strongly through the poem Maudlin (a poem about self-pity) in which Plath evokes her bitterness toward masculinity with the aid of the two characters, the Virgin and Jack. Jack is described as having a "crackless egg" an ...
