Abstract
In this article, the writer discusses that ever since Dolly the sheep was cloned in 1996, cloning has been a controversial issue in contemporary medical ethics and biomedical research. The writer notes that cloning has many advocates, as it seems to offer the prospect of cures for diseases and illnesses that are currently incurable. However, the writer points out that it also has vociferous opponents, many of whom believe that scientists have no business interfering with sacred human life processes and beliefs. The writer maintains that the media furor generated by this admission highlights the importance of this issue. Moreover, the writer discusses that there is the ongoing problem that few scientific successes have been achieved in cloning. It remains unknown whether cloning will be utilized to cure diseases in our lifetime. This essay attempts to find the facts beneath the sensationalism, and argues that cloning is undesirable.

From the Paper
"As mentioned above, the first reported successful clone was that of Dolly the sheep. This was an example of reproductive cloning, in which an embryo is created in order to grow it into a replica of the creature from which it is cloned. This is the most controversial application, as it involves creating life - and potentially, even creating human life. The process is the same as the beginning stages of therapeutic cloning, described above. However, instead of killing the embryo by harvesting stem cells, scientists allow it to continue growing, and then implant it into a womb. In the rare cases when this is successful, the embryo then grows to term and is born - an exact, new-born copy of the donor from whom the nucleus was taken."

Abstract
In this essay, the writer provides a critique of Ann Moir and David Jessel's article, which is provocatively entitled "The Differences". The writer notes that the differences to which these two authors allude are the differences that they claim exist between women's and men's brains. The writer points out that according to Moir and Jessel, it is an irrefutable scientific fact that women's and men's brains differ substantially, and moreover that this is reflected in their vastly different aptitudes, interests and abilities. The writer discusses that the authors take issue with what they clearly see as a politically correct vogue of denying that such differences exist, and urge readers to simply accept the differences as a fact of biology. The writer maintains that in so doing, they implicitly attempt to negate much of the work done by feminists to date, and arguably contribute to the backlash against feminism.
From the Paper
"In addition, given the misogyny that lurks just below the surface of this article, it is hard to believe that the authors did not have the deliberate intent of countering the feminist movement. The misogyny is evidenced for example by the fact that Gustave Le Bon's statement that many women's brains are closer in size to those of gorillas than those of men is quoted without censure, indeed, with tacit approval, as the authors then immediately go on to imply that we are in a devastating social revolution due to the fact that women are stupidly refusing to accept their inferiority. And the fact that one of the authors is a woman should not distract us from the charge of misogyny - sadly, the ranks of women also have their share of Uncle Tom's."

Click here to show/hide summary
Abstract
In this article, the writer first explains that HAART refers to highly active antiretroviral therapy. The writer then points out that antiretroviral medications are used for the treatment of infection by viruses such as HIV. The writer notes that HAART is comprised of a combination of several antiretroviral drugs. Since 1990, new antiretroviral nucleoside reverse transcriptase inhibitors have been used in combination with protease inhibitors and non-nucleosides. The writer discusses that the effectiveness of HAART has been tested in a number of ways, however, its effectiveness depends on demographic and health factors. The writer maintains that the issue of HAART is relevant to nursing since it involves the well being and effective treatment of HIV+ patients. The writer finds this relevant because many patients today are HIV+, even though they may not be aware of their status and enter treatment for other reasons. Using literary sources, the writer examines the effectiveness of HAART for HIV+ patients and what modifies its effectiveness.

From the Paper
"The purpose of Chu, Gange, and Anastos' study was to determine if hormonal contraceptive use played a part in the effectiveness of HAART. This comparative study used 77 hormonal contraceptive users and 77 nonusers. The design was a prospective cohort study since the sample was based on the larger group used by Gange, et al. The same methods were used as in the earlier study. The main finding was that HIV-infected hormonal contraceptive users and nonusers did not differ significantly in their immunologic and virologic responses to HAART. From the study, it was concluded that there was insufficient evidence that using hormonal contraceptives significantly changed the effectiveness of HAART."

In Vitro Translation, 2007.
This paper explores the procedure of in-vitro translation.
1,189 words (approx. 4.8 pages), 5 sources, APA, $ 40.95
»
Click here to show/hide summary
Abstract
The paper explains that procedures such as in-vitro translation are based upon the recognition that cells are protein-production facilities. Consequently, when medical researchers consider it necessary to make a particular protein, they can rely upon cells to produce that protein for them. The paper discusses the strengths and weaknesses of this method. The paper then discusses how molecular biologists consider in vitro synthesis of proteins in cell-free extracts to be an important method, for it offers a variety of applications.
From the Paper
"Procedures such as in-vitro translation are based upon the recognition that cells are protein-production facilities. Consequently, when medical researchers consider it necessary to make a particular protein, they can rely upon cells to produce that protein for them. Unfortunately, a number of problems have been experienced because living cells are not very good sources of exogenous proteins, for some proteins are degraded and some are toxic, while other proteins are clumped into inclusion bodies comprised of insoluble aggregates."

Abstract
The paper's proposal describes a research paper that will examine Toronto's burgeoning hi-tech and bio-tech industries; where they are located, what they look like and where they rank internationally. The paper relates that the research will focus on Affinium Pharmaceuticals in addition to other companies. The paper explains that the research should bring an appreciation for how Toronto is making a name for itself in the bio-technology sector; a sector once felt to be chiefly the preserve of U.S. centers.

From the Paper
"With a broad understanding of just what it is that different Toronto organizations do, the end research paper will explore the location of these companies. A quick perusal of one useful online map indicates that many of these organizations are indeed densely packed around the U of T (Biotechnology Ontario, "Toronto City Map", illus.1). At the same time, the fact those same organizations/companies are clustered in close proximity to the downtown financial core suggests they have wisely resolved to be as near as possible to the major financial houses and banks in the event that investment capital and loans can be secured. The final research paper will obviously spend some time looking at what enticements have compelled these various bio-tech competitors to "cram" themselves into the same small patch of real estate."

Stem Cell Research, 2007.
This paper deals with the controversial issue of stem cell research.
1,393 words (approx. 5.6 pages), 6 sources, MLA, $ 46.95
»
Click here to show/hide summary
Abstract
In this article, the writer notes that the issue of stem cell research has to do with a conflict between the need for scientific research on the one hand, and the moral issues associated with the sanctity of human life on the other hand. The writer discusses that taking human life is certainly reprehensible to most people's moral code, but there is also the issue of all the good that could come out of stem cell research, in terms of alleviating human suffering. The writer points out that the issue of funding stem cell research in the U.S.A. remains steeped in controversy and subject to severe restrictions. The writer concludes that if it continues and does one day yield almost miraculous cures, this might have an extremely positive impact on the US economy - but it might also yield even more complex moral issues, as to who gets to reap its benefits, and who does not.
From the Paper
"There is clearly a strong case to be made for this point of view. Harvesting stem cells implies that the embryo is denied the chance of growing into a human being, so it is clearly not to be taken lightly. On the other hand, proponents of stem cell research argue that in normal life, human eggs are frequently fertilized but fail to implant in the woman's uterus. Thus, a fertilized egg should not be seen as a human life, but only as potential human life - without the same rights and privileges of an actual human being. Apart from this theoretical point, proponents of stem cell research point out that in practice, the embryos utilized never had any hope of growing and being born anyway."

Abstract
In this article, the writer discusses that Alzheimer's dementia is a debilitating neurodegenerative disease that afflicts 5 million people in the United States and more than 30 million people worldwide. The writer looks at the four main drugs used in present therapy - Tacrine, Donepizil, Rivastigmine and Galatamine. These drugs are discussed in terms of their pharmacologic properties both individually and as a group. Memantine and the experimental use of tumor necrosis factor-alpha inhibitors are also mentioned. The writer notes that Memantine has shown potential in the treatment of moderate to severe Alzheimer's dementia and may have more potency when paired with a cholinergic agent although trials have yet to determine this empirically. The writer notes that the implication of TNF is still under investigation, with pilot studies showing promise.

From the Paper
"Alzheimer's dementia is a progressive neurodegenerative disease that is primarily characterized by global atrophy of the cerebral cortex, with a relatively large proportion of neuronal loss in the CA1 and CA2 zones of the hippocampus and the nucleus basalis of Meynert. Cognizant with this are the clinical manifestations of the disease, primarily a gradual onset of forgetfulness, expressive and receptive aphasia, visuospatial disorientation, apraxia and behavioral changes. However, the academic "classical" symptomology of this disease is often irrelevant in the acute clinical setting as the symptoms are often missed as components of dementia or dismissed as manifestations of ageing. Even if these changes are detected early, the progression of Alzheimer's dementia is relentless."

Abstract
This paper explains that transforming growth factor TGFa is one member of a large family of proteins that are secreted from different types of cells and regulate growth, differentiation and development. The author points out that the binding of TGFa to its receptor on target cells initiates a series of events that result in changes in gene transcription of specific genes. The paper describes the reported experiment and concludes that its results provide added information to the current knowledge base on Smads, Growth Factor - signaling and the translocation process.

"Xaio et al. (2000) performed their experiments on Smad 3 and Smad 4 protein structures that they cloned in a laboratory. This was the beginning of a long chain of events that allowed for assessing the reaction of the proteins before and after transaction . A group of control/stable cell lines was also used to transect the various GFP Smad proteins and constructs. Smad3 and Smad 4 proteins were also exposed to site-directed mutagenesis in order to mimic Smad 4's variation of Lys to Glu. Florescent microscopy was utilized to photograph the cells throughout the process before and after transaction."

Abstract
This paper identifies examples of the three different types of layers of the land: abiotic, biotic and cultural (the ABC approach) in the Agincourt area. It focuses on the relationship between those three types of layers. It then investigates how the characteristics of the ABC approach have been manifested in this particular geographical area and determines the level of integration of the various resources through the use of examples related to the ABC approach and how those examples interact.

The Area
From the Paper
"As with other areas of the peri-urban zone, it is difficult at times to distinguish what is rural from what is urban in the Agincourt area. Even though the level of urban growth is severely restricted in Agincourt, commercial expansion continues at high cost to the biotic as well as certain cultural elements. The area is a combination of rural and urban, and the priority at this time needs to become the rural. The pattern since the early 1980s is the urban aspect has dominated. In order to preserve the ecological balance between the three different types of layers of the land, what remains of the rural and farmland as well as green areas have to be preserved. The basic problem is found in a scarcity of resources which are overwhelmingly allocated to the urban or development aspect. These resources now need to be directed to preserving the rural part of Agincourt. In this way, the natural life forms or the biotic forms will be able to be sustained. The main focus has to be upon sustainability for the area of Agincourt."

Altruism, 2007.
An analysis of the role of altruism within a cohesive society.

Click here to show/hide summary
Abstract
This paper discusses the prevailing theories of altruism and attempts to develop a better contextual understanding of its core concepts. It discusses whether altruism fits into evolutionary biology and shows how altruism helps us understand how to create greater cohesiveness in society as well as encourage pro-social behavior.
From the Paper
"Understand these evolutionary theories become crucial on a societal level to leverage the altruistic intent and evolutionary instincts within human beings. Societies and leaders need to understand that mutual altruism is the only way for the improvement of the group and the survival of the individual within the group context. By leveraging the knowledge of reciprocal altruism, leaders can create a convincing argument for why it is imperative for everyone to become active members of society. Kinship selection also helps in our understanding of group activity; leaders can utilize this theory to articulate a vision for the needs of a strong and interconnected community. Human beings as evolutionary creatures have highly evolved instincts for altruism. Perhaps one of the reasons that we have survived so long and past the prime of many other animals is our sense of altruism. Therefore to understand how altruism can help on a communal level, one only has to look at the sacrifices each individual makes in every aspect of community growth."

Abstract
In this article, the writer discusses the motherhood arrangements wherein a surrogate woman is impregnated with sperm from a male unrelated to her. The writer explains that the woman then carries a fetus and gives birth to a child for another woman. The writer notes that this has always been controversial, and has typically been a scenario in which psychological issues are present. This paper examines and reviews psychological and moral issues that accompany surrogate motherhood, from several different scholarly perspectives.
From the Paper
"There are also psychological issues attached to the method used in the surrogate procedure, Edelmann explains. For example, if the commissioning woman's egg is implanted in the surrogate mother and fertilized with the commissioning woman's partner's sperm, more complicated and potentially troublesome medical issues can arise and there may be a need for "mental health care" and counselling may be required. However if the surrogate mother is simply inseminated with the commissioning male's sperm, and the commissioning woman's egg is not implanted, there is less stress and hence fewer psychological scenarios may be present.

Glutathione-s-Transferase, 2007.
This paper discusses various studies that illustrate the function of the glutathione-s-transferase enzyme.
1,179 words (approx. 4.7 pages), 4 sources, MLA, $ 40.95
»
Click here to show/hide summary
Abstract
The paper relates that high levels of dichloroacetate, a drinking water disinfectant and by-product, depleted glutathione-s-transferase's activity in studied rats. The paper reveals that those with a hereditary deficiency in the gene or enzyme appeared to have an increased risk of developing chronic obstructive pulmonary disorder (COPD). The paper looks at a study that connected the glutathione gene to the development of childhood asthma. The paper discusses another study that illustrated the significance of the glutathione gene in delaying the onset of breast cancer.
From the Paper
"Dichloroacetate or DCA is a drinking water disinfectant and by-product commonly found in municipal water supplies (Saghir 2002). It is a metabolite of chlorinated industrial solvents and many pharmaceuticals. It is quickly and completely absorbed from the gastrointestinal tract and in extensively metabolized in both rodents and humans by major metabolites. Metabolism occurs primarily in the liver, mediated by Glutathione-s-Transferase GST [zeta] (GSTZ-1) (12). DCA inhibits Glutathione and prolonged exposure of rodents to DCA reduces metabolism and depletes immuno-reactive Glutathione protein levels from the liver."

Abstract
In this paper the writer notes that there is a contest going on between conventional and alternative methods of treating sicknesses. The writer points out that conventional or traditional medicine relies on pills and other forms of mechanical intrusion into the ailing body, while alternative or holistic medicine aims at restoring the ailing body's balance by filling up its depleted energy field. The writer discusses that opponents have come up with views of the healing touch method as mere superstition, which cannot be outwardly proved, but notes that it continues to gather advocates among the public. The writer explains that the healing touch is an alternative method of addressing and correcting human illness, especially psychological illness, by intruding into the patient's depleted energy field and manipulating it. The writer concludes that the healing touch should be recommended but should not replace what is strictly within the proven or commonplace jurisdiction of traditional or conventional medicine.
Outline:
Introduction
Body
Summary and Recommendation
From the Paper
"A typical session starts with the patient sitting or lying down and the practitioner moves his hands over the patient's body without needing actual contact. The practitioner senses rough areas in the energy field. He is able to make an assessment or "diagnosis" in a few minutes. Many patients feel the sweeping motion made by the practitioner with his hands as a kind of warmth or pleasant vibration. The practitioner should desire the patient's well-being in order to produce the effect. Dr. Krieger said that the healing that follows is not a new concept. The touch somehow changes or improves the body's hemoglobin levels and this leads to the restoration of health. She insisted that the body's energy field is an electromagnetic phenomenon."

Abstract
In this paper, the writer discusses that there are a number of methods that have been developed with varying degrees of success to help women who have difficulty becoming pregnant. The writer points out that these include some of the most contemporary technologies, such as in vitro fertilization (IVF), intra-cytoplasmic sperm injection (ICSI), and various other procedures. In essence, the writer explains that assisted fertilization refers to technologies and techniques that can be used to enhance sperm-egg interaction. This paper outlines some of the most prevalent and contemporary of the infertility techniques in use today. The writer concludes that the suggestion is that reproductive cloning will advance, in a similar fashion to the acceptance of techniques like IVF, and that new techniques will be developed to improve upon existing methods of infertility assistance.
Outline:
Introduction
In Vitro Fertilization (IVF)
Intra-cytoplasmic Sperm Injection (ICSI)
GIFT: Gametic Intra-fallopian Transfer
Other Techniques
New Techniques and Reproductive Cloning
From the Paper
"There are a number of advantages to this procedure, including the fact the embryo can be fertilized inside the oviduct in its natural environment. The process also takes only about an hour and can also be performed on an outpatient basis."
"There are a number of variations to both GIFT and in vitro fertilization that are important to note. These include blastocyst transfer, or the transfer of a more mature embryo; as well as the use of donor eggs from another woman and the use of a surrogate mother and the transfer of frozen embryos."

Abstract
In this paper, the writer notes that in the past few decades, several advanced current-day fertilization techniques for women that have difficulties conceiving children have emerged at the forefront of medical technology. The writer points out that medical professionals are now able to prescribe a few different treatment options for women that are unable to get pregnant naturally. If treatment has not resulted in pregnancy after four to six menstrual cycles, fertilization techniques may be considered. The writer concludes that it appears that different techniques have roots in in vitro fertilization, which is predicted to see improvements over the next few years. The writer maintains that the future of human fertilization appears bright.
Outline:
Introduction
In Vitro (test tube) Fertilization
Third Party Donor
Gametic Intra-fallopian Transfer
Intra-cytoplasmic Sperm Injection
Conclusion
From the Paper
"Currently, in due to improvements in ultrasound imaging, surgery is no longer necessary for most in vitro fertilization patients. Technological progress has allowed for the use of a sonographically-guided needle to replace the surgical procedure which previously was used to recover eggs. This procedure, called Transvaginal Oocyte Retrieval, requires neither hospitalization nor general anesthesia. Instead, the woman undergoes about two weeks of intensive preparation, including hormonal therapy with fertility drugs. Blood tests and ultrasound scans of the ovaries are used to determine the optimal time to retrieve the eggs from the ovary, and at the proper time, an outpatient procedure under local anesthesia will allow the female's eggs to be visualized by ultrasound and retrieved from the ovary by placing a needle through the vaginal wall. The woman experiences pain similar to a pap smear and is able to return home and resume normal activities. The embryologist places the sperm with the eggs when they are ready for fertilization, maintaining them in a laboratory dish in a nutrient mixture which acts as a substitute for the environment that would otherwise have been provided by the fallopian tubes."
