Embryonic Stem Cell Research the Use of

Embryonic Stem Cell Research

The use of human embryonic stem cells in scientific research has held great promise for some but this research has also produced powerful objections from others. Indeed, there is a profound if sometimes vehemently expressed moral argument that emerges from embryonic stem cell research. The principal objections to the use of these stem cells has come from evangelicals, conservative Christians and others who equate using embryonic stem cells with killing a potential human. Those who acknowledge the potential benefits that may be derived from research using embryonic stem cells tend to people who are politically progressive, college educated individuals, and those in the field of science and those searching for treatments and/or cures for Alzheimer's, cancer, Parkinson's disease, spinal cord injuries, among other serious health issues. This paper will examine both sides of the issue, all relevant arguments, and will attempt an unbiased review of what…… [Read More]

Embryonic Stem Cell Research -

In avoiding the current controversy on the morality of embryonic stem cell research, researchers and doctors have resorted to other options (Dobson 2004, National Review 2004). Substitutes like adult stem cells and somatic cell nuclear transfer from placental or umbilical cord stem cells of newborns. Adult stem cells, however, were found to be nearly not as malleable as human embryonic stem cells or those acquired through somatic cell nuclear transfer. These were found good for reproducing red and white blood cells and platelets, but not for replacing neurons, muscle or organ tissue. On the other hand, somatic cell nuclear transfer from the placental or umbilical cord stem cells of newborns tended to be rejected by the body and developed immune reaction problems (Dobson).

Conclusion

The research showed that one of the most important, but hotly debated, issues in biomedicine in recent years has been embryonic stem cell research. The fundamental questions involved in this debate relate to the status of human embryos and whether any type of research that involves the destruction of a potential human being is morally and legally defensible. The research also showed, though, that the vast majority of the stem cells used in this research would have been discarded and therefore destroyed anyway. Although a lack of international guidelines regarding embryonic stem cell research has contributed to the controversy, the research was consistent in describing the potential, but largely speculative, beneficial outcomes that might be achieved that will benefit humankind in myriad ways. hile researchers continue their efforts to identify alternative sources for stem cells for their research, the fact remains that embryonic stem cells represent a valuable resource…… [Read More]

Embryonic Stem Cell Research in

Under the terms of Canada's proposed Assisted Human Reproduction Act outlined in September 22, 2003 issue of Health Law Review, it is not ethically acceptable to create human embryos specifically for research purposes, although "in cases where human embryos are created for reproductive purposes, and subsequently are no longer required for such purposes research involving human embryos may be considered to be ethically acceptable" if they meet certain criteria outlined in the bill (Knoppers 2003).

In November 2004, the United States and other opponents of human cloning shelved their bid for a United Nations treaty to ban the controversial procedure due to opposition by nations seeking to allow cloning from embryonic stem cell research (adhams 2004). hile there is near universal support among the 191 members of the United Nations to ban reproductive cloning, countries are still wresting over whether to allow cloning for stem cell and other research (adhams…… [Read More]

(Condic, 31) Scientists visualize immeasurable value in the application of embryonic stem cell research to comprehend human growth and the development and healing of ailments. More than 100 million Americans are ailing from the diseases that subsequently might be dealt more successfully or even cured with embryonic stem cell procedure. Majority of the researchers consider stem cell research as having large prospects for healing human ailments ever since the inception of antibiotics. (Pros & Cons of Embryonic Stem Cell esearch) Stem cells have extended much expectation by assuring largely to expand horizontally in terms of number and range of patients that could have advantage from transplants, and to entail cell replacement procedure to heal the devastating ailments like diabetes, cancer, multiple sclerosis, Parkinson's and Huntington's disease, Alzheimer's disease, spinal cord injuries, heart disease, several innumerable ailments due to rare immune system and genetic disorders and many more.

Human Embryonic Stem Cells Stem

It is only a drop in the bucket of the currently available knowledge on neural differentiation, however. According to Human Embryonic Stem Cells: A Practical Handbook, there are seventeen acknowledge and reviewed methodologies for differentiating human embryonic stem cells into neural cells (Walsh, 2008). The incompleteness and erros of this same book, however, reflect the dearth of research into the area of human embryonic stem cell research (Walsh, 2008). Though many advances have been made -- and indeed are being made right now -- the ethical concerns regarding human embryonic stem cells have proven a greater obstacle than the scientific community can fully surmount. This is not to say that ethical considerations are the only reason for a lack of knowledge, either; science, when performed carefully, is usually a slow process, and the benefits and implications of human embryonic stem cell research are far too meaningful and profound to warrant…… [Read More]

Human Embryonic Stem Cell Research

However, unlike embryonic stem cell, adult stem cell cannot be as easily controlled.

Conclusion

Because of its complicated theory and controversy, many people do not know much about stem cell research. Some people do not even know that there are two different types of stem cells: embryonic stem cells and adult stem cells. hile many people are still in favor of embryonic stem cell research, the alternative -- adult stem cells -- could be a viable technology of research was conducted on it more extensively. there are no ethical or religious objections to adult stem cell research, as it neither creates nor destroys life. This makes adult stem cell research the easier choice for society to make.

Moral issues relating to the therapeutic use of embryonic stem cells in humans

The inception of the idea of research of stem cells became plausible in several decades, in the past. Additionally, the research caused an ensuing countless debates to accompany the issue. In considering the research on the stem cell, several issues accompany the debate. These issues are either ethical, which are about the potential moral effects the stem cells may bring. The second issue is of the legal aspect, which consider the regulation of the stem cell technologies by the government and the policy makers in the helping the public (Ostnor, 2008). The last issues are social in nature, influencing and involving the society as a whole.

Value of the Embryo

Pluripotent stem cell cultures were isolated in 1981 by Evans and Kaufman from mouse blastocysts. It was found that these cells were capable of self-renewal having a long-term capacity to remain undifferentiated in certain provided culture conditions. Studies have highlighted the basic difference between stem cells and embryonic stem cells. Embryonic stem cells have the potential to differentiate into three germ layers. These cells have an…… [Read More]

Genetics Embryonic Stem Cells Embryonic

Provided with the right mixture of signals, embryonic stem cells can develop into mature cells that can function as neurons, muscles, bone, blood along with other needed types of cells. Stem cells that have this flexibility are portrayed as pluripotent, in order to indicate their high potential to differentiate into a wide variety of cell types. A second attribute of embryonic stem cells is that they have the ability to remain in an undifferentiated state and to divide forever. This ability to self-renew means that essentially an unlimited numbers of identical, well-defined, genetically and genomically characterized stem cells can be produced in culture dishes for medical use (Human Embryonic Stem Cells, n.d.).

President Obama has signed an executive order that overturned the policy that was put into place by Bush that limited federal tax dollars being used for embryonic stem cell research. This move has been hailed by advocates for…… [Read More]

Debating the Ethics of Stem Cells

The term 'stem cells' can mean different things to different people. For some, it conjures images of medical miracles providing solutions for heart disease, diabetes, and dementia. For others, it terrifies with a future filled with cloned humans. Still others cringe at the thought of mass producing cultured human embryos for the sole purpose of providing organs and tissues for a paying public. As with most complex issues, news media coverage tends to exaggerate easily understood concepts at the expense of the overall truth and the public accordingly remains ignorant of the subtleties surrounding this debate. This seems to add fuel the emergence of polarized camps and a shrinking of a common middle ground. To better define this middle ground, this essay will discuss both sides of this debate and argue instead that the vast majority of people would likely support…… [Read More]

Stem Cells Are a Hot Topic for

Stem cells are a hot topic for the media today because our understanding of them has potential for incredible scientific advances in the field of biotechnology, yet we struggle because there are questions of morality raised by the methods by which they might be used. While in centuries past, it was commonly accepted within the scientific community to vivisect the mentally insane or criminally convicted for the purpose of scientific knowledge, today religious groups are concerned about the fate of single stem cells being used in experiments. Stem cells have paved the way to cloning and bioengineering of humans, allowing scientists to "bring... A sperm and ovum together to create an embryo, harvesting the cells, and then discarding the embryo." (Celia) The concern for many people is that working with embryonic stem cells especially may somehow he breaching the rights of people and taking science to a point where it…… [Read More]

Stem Cell Differentiation the Need to Restore

Stem Cell Differentiation

The need to restore the lives of the individuals calls for more of transplantation than that which is available. There are fewer organs, which can help in the transplantation process, which means that overdependence on the process makes it to be reliable. Further, the process may also end up endangering the life of the donator. Transplantation is the only available process that can for the individuals having kidney and lung problems. However, the numbers of individuals who are suffering from kidney and lung failure are always more than those who are ready to supply the needed organs. This calls for an alternative way, which can help in compensating the loss that the individuals face. One of the major alternatives for the process of translation is stem cell differentiation that may occur in any body cell. The stem cells differentiation offer the possibility of a renewable source of…… [Read More]

Stem Cell Are Commonly Known

Study of human embryonic stem cell will lead to major advances in human biology, specifically:

Embryonic stem cell research will provide critical insights into mechanisms of cell differentiation, growth, and death (Young, 2006).

Understanding stem cells may provide keys to why people age (Young, 2006).

Scientists are interested in stem cells because they have the potential to become very practical in a way that any other kind of cell in the body might be used to replace tissues that have failed (http://news.bbc.co.uk/1/hi/sci/tech/3144925.stm,2003).

And lastly, scientists believed that if they become successful in finding cure for lymphoma, and leukemia with this study, there is a great possibility that they can also cure diseases such as Parkinson's, Alzheimer's, diabetes among others in the near future (http://www.stemcellnetwork.ca/engage/materials/presentation1.ppt,2006).

Stem Cell Policies Scientific Breakthrough

This controversial decision drew all kinds of reactions from different groups on each side of the issue. Some adversaries of hESC research expressed admiration for the decision limiting research to existing cell lines, while others said that no research should be allowed under any circumstances. Advocates of hESC research, meanwhile, generally praised the president for allowing some research to go forward, but criticized the restriction to existing cell lines as too strict, questioning whether enough research would be allowed.

Stem Cells the Ethical Controversy

Analysis of the Issues: The ethical concern for the rights and welfare of viable infants is certainly a legitimate concern, but the central ethical analysis that pertains to stem cell research revolves around the issue of defining human life appropriately. Objective criteria like anatomical development, cognitive awareness, and above all, sentience of any degree and in any form are all legitimate bases for the definition of life and for identifying the period of gestation corresponding to the earliest conceivable safeguards necessary to prevent suffering.

On the other hand, purely subjective doctrinal claims without objective criteria of any kind are wholly inappropriate bases for defining scientific concepts like when life begins. The fact that human development varies among individuals and that it may be impossible to know exactly where sentience and other elements of "humanness" first begin in the fetus does not mean that it is impossible to identify periods of…… [Read More]

Stem Cells Are Non-Specializing Cells

Dimitrios Karussis and Ibrahim Kassis, in the article, "Use of Stem Cells for Treatment of Multiple Sclerosis," conclude,

"In the current review, the various types of stem cells, which were mainly studied in animal models, will be reviewed as a potential therapeutic approach for MS. The main and common mechanisms of action of all stem cells include induction of neuroregeneration and remyelination through the activation of resident stem cells, or production of new CNS cell lineage progenitors, paralleled by local and systemic immunomodulating effects" (Karussis & Kassis, 2007, Conclusion ¶).

The other diseases that are showing promise in treatments resulting from stem cells usage includes: as cancer, diabetes, osteopetrosis, rheumatoid arthritis, Alzheimer's disease, Parkinson's disease, spinal cord injuries, heart disease, immune system disorders, blood disorders; the list goes on (Diseases Treated by Cord lood, 2010).

Stem Cells

ithout a doubt, one of the most controversial topics of popular discourse is stem cell research. Indeed, one would be hard pressed to peruse the newspaper or magazine stand without encountering some reference to the global stem cell debate -- but what, exactly, are stem cells, and why are they so controversial?

Stem cells intended for use in human applications are harvested from humans, umbilical cords and embryos. The reason these cells are so valuable is because of their capability to produce or "become" other cell types -- for example, brain cells, heart cells, skin, etc. In short, these are "master cells," holding the ability to divide in cultures, and to be manipulated allowing it to transform into any type of cell. Of course, this is extremely important due to the fact that scientists can use this capability to either create organs (thereby helping to meet the tremendous…… [Read More]

Stem Cells It Will Consider the Current

stem cells. It will consider the current moral discourse on the issue of stem cells and at the same time look at the basics or the foundation of stem cells themselves. How these cells can be utilized to conduct studies in cloning will be dwelt upon as well.

The pertinent issue on the floor of the U.S. congress in the deliberations on stem cell studies on humans is how to handle embryonic stem cell research (ESR), a kind of research that may generate crucial lifesaving therapies, which demands the damaging of embryos. Present national government regulations and policy documents tackle this issue basically via the limits on federal funding allocated to ESR (Aylesworth, 2010). The U.S. Department of Human Health Services is not permitted to spend any money on making human embryos for studies whereby the embryos will be damaged, thrown away, or intentionally be exposed to risks such as…… [Read More]

Stem Cells and Umbilical Cords

Scientists have been aware of the existence of these stem cells for many years but have only recently realized the potential medical applications of the cells. More than a decade ago, scientists discovered that if the normal connections between the early cellular progeny of the fertilized egg were disrupted, the cells would fall apart into a single cell progeny that could be maintained in a culture. These dissociated cells, otherwise known as embryonic stem cell lines, continue to divide in culture, producing large numbers of cells at a fast pace. However, these early embryonic cells would lose the coordinated activity.

Scientists quickly discovered that these cells retain the ability to generate a great number of mature cell types in culture if they are provided with appropriate molecular signals (Reaves, 2001). Scientists have made significant progress in discovering these signals and are still working on it. hile it is a difficult…… [Read More]

Use of Stem Cells in Parkinson's Patients

Stem Cell Research / Parkinson's

Since Barack Obama has become president, the field of stem cell research has been given new life. One of Obama's campaign pledges

was to allow deeper research -- including the use of federal research funds -- into the use of pluripotent stem cells in order to find solutions for some of the terrible diseases Americans suffer from. Among those medical problems is Parkinson Disease (PD). This paper reviews and delves into the literature in terms of the potential of stem cell interventions into Parkinson Disease (also called "Parkinson's Disease").

ho is the leading authority on stem cell research?

There is no one "leading authority" reflected in the literature; however there are renowned scientists that are considered pathfinders in this field. Dr. Diane S. Krause, Associate Professor of Laboratory Medicine and Associate Director of Stem Processing at Yale University is "…one of the discoverers of previously…… [Read More]

Healthcare Ethics -- Stem Cells

While freedom of religion absolutely guarantees the right to refrain from choosing to submit to stem cell-based treatment, the same freedoms and the concept of separation of church and state absolutely preclude religious beliefs about when life "begins" (or about anything else) from dictating laws that affect other people who may not share those particular beliefs (Dershowitz, 2002).

Beneficence and Non-malfeasance

Certainly, both the concept of beneficence and non-malfeasance absolutely prohibit the use of fetal stem cells from any fetus that is sufficiently developed to be considered a "person" as well as from any fetus that is sufficiently developed to sense pain. Medical authorities may debate where the exact point is where "personhood" first becomes an issue, but in principle, that characterization must be a function of objective criteria and never subjective beliefs of laypeople, especially based in religion (Dershowitz, 2002).

Both beneficence and the duty to avoid malfeasance prohibit…… [Read More]

Political Influence Over Stem Cell

Going back further, the same religious principals also inspired opposition to organ transplants and blood transfusions; before that, the Catholic Church strictly forbade any forensic scientific research, necessitating the need to dissect cadavers for medical education entirely in secret (Levine, 2008).

Just as the news media are partially at fault today for their failure to distinguish legitimate concerns from ludicrous fears in connection with the ongoing political debate over American healthcare, they are equally responsible for allowing unfounded fears of "human cloning" in connection with the beneficial uses of stem cell science. Specifically, the main source of secular opposition to stem cell research is attributable to unnecessary fears of rampant misuse of human cloning technology to clone human beings. While human cloning is hypothetically possible, no responsible scientific researcher would ever misuse current biomedical technology in that fashion. The complexities of cloning entire organisms have been well documented in animal…… [Read More]

Ethics Behind Stem Cell Research

Do patients understand what it means to donate tissue to science? Not only that, but use of EG cells confuses stem cell research with the debate over abortion, bring up the risk of biasing emotions (McDonald 7).

So, while stem cell research is an exciting new field that holds much promise, ethical problems arise to delay research, discovery of benefits or dangers, and involve many who have no knowledge of the complexities of the field. Though controversies usually accompany new discoveries in science, this biotechnological process involves manipulating the basis of life itself in embryonic stem cells. But the field is rapidly changing. hat is true today may be outmoded tomorrow. A neutral substitute for stem cells may be discovered that will prove to be the answer to these ethical questions.

This bill was sent to the U.S. Senate and set for vote mirroring a bill previously passed by the House during the Summer of 2003 which failed to pass the Senate because of vehement disagreement that was even "within the parties over the prohibition of therapeutic cloning.(National Legislation Concerning Human and Reproductive Cloning, 2004; paraphrased) As of the date of the report on legislation eight U.S. states had passed laws that explicitly prohibited reproductive cloning using human embryos and another five U.S. states have placed a prohibition on cloning for any purpose whatsoever with 22 other U.S. states introducing bills outlawing the reproductive cloning of humans.

Stem Cell Genome Reparations

Human Genome, Stem Cells, & Reparations

Stems Cells are the source of all body tissues. Growth and development of the human body arises from the stem cell and is maintained by it. Although all cells can divide or copy themselves, stem cells are unique because they can replicate and create all other types of cells. This ability of the stem cell to develop into any of the 220 cell types that make up the human body makes it a powerful tool for biological research and medicine. Scientists believe that stem cell research has the potential of leading to previously incurable diseases.

How are Stem Cells Formed?

Moral and Legal Questions of Stem Cell

Moral and Legal Questions of Stem Cell Research

Stem cell research is an experimental, and research-based study as to methods of repairing the human body. y introducing stem cells into a damaged, or degenerating area of the body, the medical profession hopes to prompt the body to regrow healthy tissue, and repair the damage. Degenerative diseases, such as Parkinson's disease, or macular degeneration of a patient's eye retina are conditions in which the healthy tissues cease to function properly. There is no overt damage. There is not a disease which has physically destroyed the affected body part. ut for varying reasons, such as old age, wear and tear, or reasons medical science does not yet understand, the affected body part simply ceases to function properly. Stem cells are the type of cells, which are more numerous in, but not limited to, human embryos. They are the building blocks of the…… [Read More]

Philosophy Required in High School

Obama endorsed an Illinois handgun ban while he was serving in the Illinois state legislature and also supports a ban on semi-automatic weapons. However, the current President professed his support for the Second Amendment, stating that he supports restrictions to keep guns out of the wrong hands, not a full prohibition. In Illinois he co-sponsored a 2000 to limit consumer purchases of firearms to one gun per month -- although he also supported 'conceal carry' laws for retired police officers ("Gun control," on the Issues, 2008).

The spike in gun sales has more to do with political posturing than reality: gun owners wish to demonstrate their opposition to Obama's system of values, as conceptualized in the red-blue divide that currently exists in the United States. In this polarized media positioning, Obama represents urban elitism and government control, despite his actual policies. The NRA and the gun industry has used this…… [Read More]

Though
this is, of course, never the case, anti-stem cell research activists
affiliate this issue as a slippery slope with the abortion issue.
However, to my perspective, this is an incredibly inhumane
politicization of a prospect which could save many lives and reduce much
suffering. Obstruction to advancement in this field are short-sighted and
cruel. The condition of cystic fibrosis is a good example of a condition
where the effective use of embryonic stem cell research would be considered
a means to reducing much pain in its sufferers. Here, the dysfunction of
the secretory glands creates excessive mucous production and can result in
life-shortening respiratory and developmental issues. If embryonic stem
cells are differentiated and transplanted to produce healthy, functional
secretory glands in the sufferer, this serious and distressful condition
could be diminished in presence.

Embryos and Fetuses in Research

3. Embryonic stem cells can be used to help human beings who suffer from debilitating diseases for which no other solution offers hope. For this reason alone, the research should be legal, considering that the embryos from which the stem cells are derived cannot be shown to possess any type of noticeable consciousness. There is no moral reason to favor the use of animals in medical research over the use of embryonic stem cells, considering that the former are fully developed creatures who clearly have the potential to feel pain, whereas the latter demonstrate little more than potentiality. Furthermore, most embryonic stem cells are culled from discarded tissues used for in vitro fertilization. If in vitro fertilization is legal then so too should be the proper use of the leftover cell mass.

Utilitarian Thinking

stem cell research has been controversial for years. What are stem cells and why do they entail so much interest? Stem cells may be derived from embryonic, fetal, or adult cells and tissues. Potentially, the embryonic stem cells can serve as the machinery to repair, regenerate, and/or replace tissues and organs. In other words, they could prove invaluable in eradicating all illnesses and incurable conditions. Following an ethical perspective, the doctrine of Utilitarianism supports stem cell research.

Utilitarian theory proposes that the desirable consequences of an action justify it for the greater good, and for its short or long-term benefits (osenstand). In the matter of stem cell research, the desirable long-term consequences are those of scientific advancement within the healthcare domain, improved health value for all human beings, and financial preservation for all citizens of the world, that would no longer spend so much currency on medicines if they were…… [Read More]

For some the issue then arises when the pluripotent cells are removed from the blastocyst, as this very act negates the ability for the cell group to develop into a human being. "Note that the process of changing from totipotent to pluripotent to multipotent cells is not reversible -- that is, pluripotent stem cells do not produce totipotent stem cells, and multipotent stem cells do not produce pluripotent stem cells."

Borror, O'Rourke and Skirboll 54) Additionally, the proponents of stem cell work cite the pluripotent as incapable of producing a human being therefore not a destruction of life, hence leading to the Bush decision to ban the creation of new lines of stem cells, as it would require the destruction of further human totipotent cells.

(Marsh, 1) Equally as groundbreaking as the creation of the world's first clone was the implication of its process, which indicated that there is a way to employ adult cells, already differentiated and specialized to their own organic functions, in order to fabricate new, un-differentiated genetic material. For researchers battling such diseases as Parkinson's, Alzheimer's and paralysis all around the world, such a possibility began to hint at countless opportunities…… [Read More]

Altering the Universe From Gutenberg to Biotech

Altering the Universe: From Gutenberg to Biotech

Revolution is in the air. hile the digital revolution is transforming our view of the universe, the biotech revolution has the potential to alter the universe itself. The parallel with the invention of the printing press and the Renaissance is clear. (Blake, 2001). "Gutenberg's and Caxton's inventions turned the world figuratively and intellectually upside down and heralded new patterns of human activity and organization that were inconceivable prior to the early 15th century." (Blake, 2001, pg. 9). One of the great achievements of that era was the quick adaptation of this communications revolution to every aspect of human life. Today, "we are at the beginning of a new Renaissance...." (Blake, 2001, pg. 9). One of the more controversial elements of this new Renaissance is stem cell research. There is perhaps no field fraught with more possibility along with questions of morality and medical…… [Read More]

1950s to Scientific Technology of

Study Limitations. There is no doubt that the issue of stem cell research and cloning carries with it scientific obligations, moral concerns, and future possibilities (obertson, 2000). However, authors such as osenthal and Lanza have managed to put the issue squarely where it belong at this juncture, namely, controlled empirical investigative research. The authors, although, thorough in their presentation, did little to encourage the on-going process of stem cell research for regenerative medicine. The limitations of their research presentation include the following:

No direct relationship was established between animal stem cell research and human stem cell research.

Mention was not made with respect to the costs of current stem cell research efforts and possible future costs.

Emphasis was not place on the overall need for advanced biotechnology.

Documentation between government regulations and current stem cell research efforts was not addressed.

The authors did little to address the potential stem cell…… [Read More]

Human Progress Is the Ultimate

On the other hand however, it gives rise to an exclusive attitude and a multiple layer style of development and economic evolution because there will always be countries that fail to keep up with innovative technology, high tech research and revolutionary concepts which stand at the basis of today's creative industries. This is why the population in least developed countries does not consider globalization as being benefic for the improvement in their standard of living.

All in all, it can be said that the success and nature of a process is totally dependent of the perspective which is under analysis. Concerning stem cell research, arguments coming from the medical point-of-view favor the continuing of the research while those embracing the religious and ethical perspective strongly disagree. Similarly, depending on the point-of-view, globalization can be seen as both an inclusive and an exclusive process.

Bush Religion the Religious Policies

Proponents of stem-cell research believe that it may be the secret to curing infertility, genetic imperfection and neurological degeneration, and on the premise of this supposition, have lobbied vigorously to prevent legislation that would protect embryos from harvest and use in research, espousing the idea that:

"Criminalizing human reproductive cloning in the United States will only make it less safe and more costly for these infertile couples. They will be forced to travel outside the United States to pursue their dream of creating a family. After all, according to the Americans with Disabilities Act (ADA), infertility is a disability and reproduction is a major life activity for the purposes of the ADA (Bragdon v. Abbott, 118 S.Ct 2196; 1998). In light of this, it is the right of each and every American citizen to bear a child." (Speeches, 21)

In spite of this, there were very few legislative efforts which…… [Read More]

Beneficence the Field of Nursing Is Shaped

Beneficence

The field of nursing is shaped by a range of ethical principles; while all of these concepts are important, one could argue that perhaps the most crucial ethical principle is that of beneficence. "Beneficence is the obligation to do good and avoid harm. Nurses help others to gain what is beneficial to them, which promotes well-being and reduces the risk of harm" (Young et al., 2009, p. 75). Having a clear understanding of beneficence is important as nurses are often presented with a range of complex ethical situations and dilemmas and they need strong principles to help guide their actions and nursing practice. As Young and colleagues explain, avoiding the harm that comes to a patient involves balancing this against the perceived amount of benefit. Other theorists see this concept in a slightly different perspective: "Beneficence is the principle of promoting the legitimate and important aims and interests of…… [Read More]

Controversial Bioethical Issues of the

Chimpanzees and gorillas can be taught human sign language, and sign with one another even without humans present. (MMMC, 2002) They argue that to use intelligence and compassion as a sliding scale of the right to life would cause many humans to be justified out of existence.

However, even if one accepts that too many animals are experimented upon, and researchers should use other means, it is similarly hard to justify the elimination of all animal experimentation, altogether, as this would have meant the end of such recent drug developments in AIDS research, as well as more questionable animal tests, as for instance, the use of rabbits in cosmetic testing, for which there are acceptable substitutes that do not require animals.

Christopher Reeve Case Study Christopher

hat treatments did the individual seek? ere any available at the time?

Reeve had to have a major operation a few days after his accident to replace the shattered vertebrae through artificial means. After his operation, he was put through physical rehabilitation and occupational therapy. Eventually he was able to move his wrist, fingers, and feet (Hecht & Hecht 2004). He could also breathe without assistance for up to 90 minutes. Intense physical therapy continued throughout the remainder of his life. Other treatments he received included: weight-bearing exercises, calcium supplements, and medication to reverse osteoporosis, or thinning of the bones which happens frequently to paraplegics.

Reeve sought further means of overcoming his disability, particularly with stem cell research. In this therapy, embryonic stem cells or, less often, adult stem cells are introduced to the damaged body which and allows the body to regenerate damaged tissue. It has been shown to…… [Read More]

Physiological Perspective the First Trimester of Pregnancy

physiological perspective, the first trimester of pregnancy is when the majority of fetal development occurs, and also when the full development of the placenta occurs. The first twelve weeks or so after conception see the transformation of a fertilized egg cell into a fetus that shares blood flow with the placenta through the umbilical arteries and vein. As a result, these twelve weeks are particularly crucial for the health and development of the fetus at its most vulnerable stage. Among numerous other physiological changes, the mother's nutritional intake needs (which include vitamins and minerals) increase substantially, so nutrition is crucial. The avoidance of alcohol is necessary to avoid birth defects caused by the substance: as Blackburn notes, "drinking alcohol at any stage of pregnancy can affect the brain and other areas of development" (Blackburn 2007, 221).

Adrenal Gland Keeping the Body

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…… [Read More]

Bioethical Concerns Regarding the Use of Human

bioethical concerns regarding the use of human stem cells involve their source and their research implications. Ethical issues surrounding the source of human embryonic stem cells used in research has historically evoked the most intense debates and other ethical issues have surfaced concerning the origin of other human embryonic stem cell -- like cells that have the capability to differentiate into all different types of human tissue.

From the time human embryonic stem cells were first isolated and cultured in 1998 human embryonic stem cell research has been generated vast controversy (Cohen, 2007). Much of the controversy is related to the historical public suspicion concerning the potential negative impact of scientific progress and research centered around genetic cloning. Human embryonic stem cell research has become equated with fears about human cloning, the modification of human biological material, and myths of regenerative immortality in wealthy people. All of these vague fears…… [Read More]

Unethical Experimentation Issues and Concerns

(Freyhofer 104)

Globalizing clinical research has reportedly proven to be one solution for America's pharmaceutical paradox. Doctors prescribe more than 10 prescriptions for the average American each year. Only one person in 350, however, will submit themselves to be a participant in experimental drug testing. On the other side of the globe, however a profusion of under-treated, poor, physician-trusting patients who live in Latin America, Eastern Europe, and Southeast Asia provide the rapid, positive results needed for new drugs to receive quick approval. One review noted that 99% of controlled trials published in China netted positive results upon the drug/treatment being investigated. (Shah 23) In Nigeria during 2002, thirty Nigerian families filed a class-action suit against Pfizer, who allegedly violated the Nuremberg Code in 1996 as they presided over an experiment on Nigerian children suffering with meningitis. esearchers reportedly forced a risky, unapproved, experiment on unsuspecting subjects who, as a…… [Read More]

Perspectives from the Liberals and Conservatives about Government Functions

Liberals and Conservatives
Liberals postulate that the government should act towards ensuring equality for all. The government has a responsibility of protecting human rights, civil rights and eliminating social ills. Therefore, the government’s major role is to ensure that no one is needy. Generally, they insist on the necessity of the government to handle difficulties. (Graham et.al 2009)
Conservatives emphasize on individual liberty, personal responsibility and free markets. In this case the government’s role should be to empower people to be able to pursue their goals and solve their own problems. (Lakoff, 1997)
Both liberals and conservatives have various policies. The first policy we will talk about is death penalty. According to liberals, death penalty is ‘cruel and unusual’ and it should be abolished as every instance such an execution is made, there is a risk of killing an innocent person. However, conservatives believe that death penalty is the ideal…… [Read More]

Isolate One Issue That Could Be Called

isolate one issue that could be called the most controversial issue of the last decade, then it would have to be stem cell research. Federal funding for stem cell research has come under serious criticism on ethical grounds. Stem cell research has been the most explosive genetic research subject in recent years. It has occupied political, legal, ethical and social debates without any specific resolution to the question if stem cell research is ethical and if yes how and if no, why. The debate is grounded in the source of cells required for the research. Stem cells are obtained from two or three different sources like the umbilical cord and the very early stage embryo but the main contentious source is the early embryo which is rich in stem cells but has not yet turned into a person because at this stage it is simply a cyst called blastocyst.

Ian Wimut and Keith Campell could effectively clone two sheeps named Megan and Morag in July 1995 from the differentiated emryo cells. (History of Cloning)

Dolly originated on July 5, 1996 as the first organism ever to e cloned from adult cells. Following the announcements for creation of Dolly y Ian Wilmut, an extensive deate on human cloning ethics emerged and that led President Clinton to propose for a five-year moratorium on federal as well as privately invested human cloning research on March 4, 1997.

Patenting Living Things and What

A "New York Times" reporter notes, "But unlike some other patents on animal cloning, this one does not specifically exclude human from the definition of mammals; indeed, it specifically mentions the use of human eggs" (Pollack). Another writer notes that there are virtually no limits on what a patent can be issued for, and so, the patent office can potentially issue patents on any number of controversial or ethical procedures and creations. He writes, "Under this approach, the U.S. Patent and Trademark Office (USPTO or the Agency) issues patents on 'anything under the sun made by man'" (Bagley). Clearly, this policy can lead to muddy waters and questions of morality in the future. Most people agree that human cloning should not occur for any number of reasons, including the ability to create humans and even "perfect" humans to serve as workers or in effect "slaves." This is a moral and…… [Read More]

Current Events on Cloning and Evolution

Topic and Date: The Ethics of Egg Manipulation (Evolution), August 27, 2009

Nature

The article "The Ethics of Egg Manipulation" published in Nature investigates the research challenges in reducing diseases that can be identified prior to egg fertilization. Scientists have questioned if it is necessary for humans to give birth to offspring that are at high risk for genetic diseases. Their hypothesis is: If we remove the bad parts of the DNA from one egg and replace it with good DNA from another egg and use the new egg for in vitro fertilization, can we reduce the number of babies born with disease (Anonymous, 2009)?

Current experiments have been performed on monkeys. The experiments have been successful and scientists believe the research is ready to move to humans, but many laws are in place to deter this type of…… [Read More]

Bioethics Final

This portfolio documents performance of key class and personal objectives for HU280-01: Bioethics 1103C, specifically analytical skill building, knowledge acquisition and practical application. The samples demonstrate achievement by presenting excerpts from submitted assignments, Discussion and Seminar interactions, interactions with the instructor and reflections on progress mastering central concepts, ideas and perspectives in bioethics. This work demonstrates a progression from identification, synthesis and recapitulation of selected relevant ethical systems, placing those systems in the contexts through which they arose, and applying those precepts to emerging controversies in modern life. The underlying benchmark this presentation attempts to demonstrate is that if learning is indicated by a change in behavior, then my implementation of new methods considering bioethical dilemmas and also improved critical reasoning and research methods, indicates learning over this process of course inquiry.

This process has provided a structural framework that translates directly to my work…… [Read More]

Abortion Pro Life Not Many

"It is not just a Catholic and Protestant Debate"(13).

Some Catholic statements, like the 1968 papal encyclical Humanae Vitae, condemn the practice on grounds of the created order, which is thought to be structured in such a way that all sexual expression must be open to procreation. Other statements, notably various declarations issued from 1969 to 1989 by the National Conference of Catholic Bishops (NCCB) in the U.S. appeal instead to the nature of the human person and the idea that life begins at conception. Abortion must be rejected, such statements argue, because it terminates a human life. Yet a third subgroup can be identified. Statements like the NCCB's well-known 1983 pastoral on peace and the Catholic bishops of France's 1979 declaration do not emphasize the doctrines of creation and human persons but argue against abortion by granting priority to the gospel.

In addition, in the Protestant Church, several statements…… [Read More]

Insufficient or Inadequate Information Is Usually Seen

Insufficient or inadequate information is usually seen as the greatest threat to the integrity of an argument. However, the fact is that even arguments, which are supported with a great amount of information, can prove to be faulty because of structural weaknesses. For example, suppressed, ignored, or unconsidered evidence can invalidate conclusions. Similarly, biased assumptions, failures in logic, and the neglect of counter-arguments can all lead to fallacies in reasoning (UNB, para 1). Thus, it is evident that critical thinking necessarily involves the consideration or avoidance of logical fallacies if it is to succeed in being "...purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanation of the evidential, conceptual, methodological, criteriological, or contextual considerations upon which that judgment is based." (Facione, 1998, p. 14) There are a multitude of logical fallacies that may occur in reasoning or arguments. Since it would not be possible…… [Read More]

Environmental Settings of the Cambrian

" (Sukumaran, 2004) Mutation is what results in the difference and may be utilized as a measure of the time that has elapsed since separation of the species from the common ancestor during evolution. This is a method of "inferring the divergence of time of clades from a common ancestor by means of gene/protein sequencing" and has been termed 'molecular dating'. The process is one in which there is a calibration of time in comparison to the Phanerozoic era fossil data and then expoliation is conducted for providing the estimation time for divergence of phyla. (Sukumaran, 2004; paraphrased) Indeed, if life did evolve as posited in the work of Charles Darwin then "the abrupt appearance of diversified life at the beginning of the Cambrian period was not explainable." (Sukumaran, 2004) However, Sukumaran explains that gradualism is not a central tenet to the idea that there has been an evolution of…… [Read More]
