From the Paper
"This biological psychology paper will discuss left brain/ right brain differences. What is meant by left brain/right brain differences are differences between the two major hemispheres of the brain, the right hemisphere and the left hemisphere. The focus
will be on how the hemispheres differ functionally to affect psychology. A number of studies will be summarized.
II. Biological Aspects
Study of patients with damage to only one brain hemisphere is used to deduce how the right brain and left brain are different-iated. Robertson and Delis (1986) note that patients with damage to the left brain have more difficulty in visuospatial part-whole processing than do patients with damage to the right brain."

Abstract
This paper discusses the problem of medicine's inability to induce antigen-specific immune tolerance, the final technical obstacle to bringing face transplants into widespread clinical application. The paper presents an overview of historic and current immunological research - from the use of chimerism, to the use of monoclonal antibodies to control T-cell activation - and its role in future prospects for a non-pharmaceutical strategy for tolerance induction in humans. The paper highlights studies that have examined tolerance in recipients of composite tissue allografts (CTAs), with emphasis on studies using animal models involving skin allografts, and with the intent of providing insight into the issues presented by transplantation of a face. It includes graphs and photographs to illustrate this.

Conclusion
From the Paper
"Investigators are exploring several strategies in an attempt to provide medicine with safe and effective pharmaceuticals and clinical protocols for inducing tolerance after transplant. These include creating and using chimerism, and developing targeted bio-engineered monoclonal antibodies to inactivate or destroy T cells. This review, in its overview of historical and current immunological research, provides insight into the development of a T-cell-based strategy from a basic understanding of chimerism. This review also highlights studies that examine tolerance in recipients of CTA transplants, with specific emphasis on those using skin allograft animal models."

The Denial of Liver Transplants to Alcoholics, 2007.
A discussion of whether it is ethical to deny liver transplants to alcoholics.
2,940 words (approx. 11.8 pages), 6 sources, MLA, $ 86.95

Abstract
This paper examines the criteria used to determine who may receive a liver transplant and, in particular, whether alcoholics should be allotted livers for transplant. Alcoholics tend to be given low priority status on liver transplant waiting lists or are even taken off such lists because they are considered responsible for their organ's diseased condition. The paper questions whether the denial of transplants based on this moral criteria is justified. It concludes by arguing that alcoholics should be given the same priority level as non-alcoholics on the same transplant waiting lists.
From the Paper
"Deciding who should receive organs is not based solely on medical need, but also on moral criteria. Initially, patients must display a genuine medical need for a new organ, meaning that they will indeed die unless they receive a transplant. Then they are eligible to be placed on a waiting list. Patients on the list are then chosen one-by-one as organs become available (Kilner 5). However, it is most certainly always the case that the available organ could potentially be given to more than one person on the list. In this situation, a single recipient must be chosen. A team of physicians and a psychologist determine which patient will be given a new chance at life through the transplantation of a new organ ... but how exactly do they decide?"

Abstract
Heart transplants have become a modern medical practise today thanks to improved techniques and drugs to suppress the immune system so that the body will not reject the new heart. This may seem like a medical miracle, but there are those who disagree. The advent of heart transplants has given rise to several social issues and the paper discusses several of them such as psychological issues, issues with consent from the donor family, prioritizing of patients according to social status, an organ ?black market?, and cloning.
From the Paper
"Organ transplants and other new techniques being researched will someday improve the lives of those for which time has run out. This new technology is a blessing for the patients who receive it, but is also a source of social and moral dilemma. Each technique has its own associated problems and the solutions are currently few. There are some issues which society may never resolve such as the religious issues involving heart donation or stem cell research. There are many issues involved with heart transplants. We also may never know if the stories are actually true about black market organs and corrupt doctors. It is doubtful that any of these people will actually confess. Heart transplants bring bring the promise of new life, but they also bring the promise of many more years of social debate. "

Abstract
This paper addresses the following two questions. Should a significantly health-compromised patient be granted a second set of organs if there is a significant and statistically abnormal chance of death during or following surgery? And should the fact that a gross medical error during transplantation is the cause of the patient?s compromised condition be an influencing factor in regard to the aggressiveness with which an assignment of future organs is pursued?
From the Paper
"The first issue at hand, namely if a health compromised patients, at significantly greater risk for an unsuccessful outcome be granted transplant organs is an old one. Of course, it is based on the fact that there are simply not enough organs to go around. In fact, according to current estimates, it is estimated that among the 80,000 patients awaiting transplants, an average of seventeen die every day in the United States alone simply because an organ never becomes available (IHI). Given this reality, many have proposed that the method by which transplant candidates are ranked on the national transplant lists depends not only on the severity of the need, but also on other factors relating to overall health, lifestyle, as well as age."

From the Paper
"Modern medicine's successes and failures in the field of skin organ transplants are the product of historical trial and error. However, as society now deals with the ethical, socioeconomic and legal issues surrounding what many term a "miracle" of science, the ramifications of transplants, organ transplants in particular, have gone far beyond what was imagined. Each year, the lives of thousands of people in the United States are dependent on this surgical procedures causing scientists to push the boundaries of transplants even further. These unchartered waters are both exciting and frightening.
Though there were references to skin transplantations in the early Egyptian manuscripts dating from 2000 B.C., and the 1800s witnessed the success of such operations, it has been the advancements in the last four decades which have brought about ... "

Abstract
This paper discusses metastatic breast cancer, cancer that originates in the breast and moves to lymph nodes and other bodily tissues. It provides a research study on its treatment using high-dose chemotherapy (HDC) followed by an autologous stem cell transplantation (ASCT). It analyzes its efficacy and safety as well as some of the arguments that state that the effectiveness of HDC/ASCT may vary according to various non-treatment related factors-- age, stage of disease at diagnosis, hormone receptor status, use of prior adjuvant chemotherapy, initial disease-free interval, response to prior chemotherapy and number and sites of metastases. The paper includes tables of figures and diagrams.

"Stress is another factor affecting treatment outcomes because high levels of stress may directly impact patients; both their mental and physical health. A study on post-traumatic stress disorder in stem cell transplant patients confirmed harmful effects on patients? quality of life. This study was not limited to patients with metastatic breast cancer, but was completed in a similar way as the previously mentioned studies that recorded personal health. Patients were asked to fill out questionnaires to judge if they were suffering from post-traumatic stress as a result of stem cell transplant. It was reported that the week before the transplant, approximately half of the patients had the highest levels of distress, which declined only slightly after the transplant was completed (Wettergren et al., 1999). The body?s response to stress is complicated involving several organs, hormones and responses. This is extra energy that the body is expending and is therefore less able to focus on the task of recovery."

Organ Transplants, 2006.
A review of Dr. William Beschorner ideas regarding organ transplantation.

Abstract
This paper reviews and discusses Dr. William Beschorner and his belief that organ farming is a solution to the lack of organs readily available for donation and transplantation. According to the paper, specifics of his research deals with how to get the human body to adopt an animal organ, as it is the natural response of our bodies to reject anything alien.
From the Paper
"The core concept behind his revolutionary research is that by injecting cells from a potential donor into the host, the host will be able to accept transplants later on. This technique was successfully used between sheep and pigs. Beschorner used this technique to inject bone marrow from sheep into fetal pigs. As a result, the pigs were born with a tolerance to sheep cells. The pigs that were produced ultimately are transgenic, which means that they have genetic material from two different species within their body. Using the same strategy, he was able to transplant the aorta of these pigs into sheep with strong acceptance rates. He has found that "the tolerance goes both directions, the pig become tolerant to the sheep cells, and the sheep cells in the pig are programmed to become tolerant to pig cells" (NPG). This revolutionary technique is what Beschorner wishes to adapt to the next stage of his experiment. In one experiment, Beschorner grafted pig hearts onto the necks of the sheep. As a result, the sheep's blood would flow through the heart but it didn't replace the sheep's own heart. Such experiments demonstrated that only seven of the thirty five within the test actually experienced vascular rejection, whereas all of the sheep receiving hearts from unmodified pigs exhibited vascular rejection."

"Bone Marrow Transplantation
One application of immunological methods to the treatment of human disease is bone marrow transplantation. During the 1960s, various technological advances led to the rapid development of this therapeutic modality. Perhaps the most important advance occurred in the field of transplantation immunology. Since that time, bone marrow transplantation techniques have acquired considerable sophistication. Currently, they are used for a variety of disorders including the leukemias, severe combined immunodeficiency states, osteoporosis, and various inherited diseases. In addition, bone marrow transplantation is also being considered for use against certain types of solid tumor.
The basic transplantation procedure is actually relatively simple (3:519). Multiple bone marrow aspirations are simply taken from a donor..."

Ectopic or Heterotopic Brain Tissue, 2002.
This paper gives an overview of ectopic brain tissue, extracranial brain tissue that is not directly connected to the brain itself.
3,987 words (approx. 15.9 pages), 10 sources, APA, $ 108.95

Click here to show/hide summary
Abstract
The paper shows that extracranial brain tissue that is not directly connected to the brain itself may be an isolated cutaneious embryonic defect. It discusses how these are usually located on the occipital or parietal areas of the scalp and are often called heteropic brain tissue or cutaneous ectopic brain (CEB). Most of the time these are simple defective tissue that can easily be removed from the scalp. However, there are several different types of ectopic brain tissues and some of these can be signs of underlying central nervous system problems. The paper discusses several cases where the importance of getting a thorough evaluation of the tissue is shown.

From the Paper
"Perhaps the question can be asked why the researchers termed the phrase, ?hair collar?. Why is there a hypertropic ring of long hair that surrounds these lesions? If these were examined, the hair follicles would be found to increase in number and many of these will be quite large. In fact, the angle that each hair follicle exits the skin does not fall randomly, but are located at precise directions that the hair follicles take.
? The hair pattern is thought to be dictated by differential shearing forces and the point of maximal tension, the vertex, is where the parietal scalp whorl is commonly found. Perhaps at some point early in development, encephaloceles and meningoceles produce aberrant shearing forces during the formation of the follicles forcing them to point outward, away from the defect?

Abstract
This paper looks at how transplant recipients have an abundance of learning needs after receiving their transplants and how patient education is a crucial aspect of the transplant nurse's role. It examines how transplant recipients must learn follow-up instructions, signs of rejection and infection, medications and their side effects, urine testing procedures, and dietary and lifestyle modifications in order to ensure transplant viability and increased quality of life. It proposes a study to examine the effect of the method of teaching on the cognitive learning of adult kidney transplant recipients and concludes that individual patient teaching in adult postoperative kidney transplant recipient patients results in increased cognitive learning.

"The fact that a transplant recipient must take medication for the rest of his or her life means that there is a higher chance of specific medical problems. While this increased risk cannot be avoided, there are things that can be done in order to help minimize these particular risks. Patients must be informed, however, so that they can continue to maintain a high standard of self-care as much as possible. They also need to be aware of what problems they might face so that they can see their doctor if issues arise. Professional nurses are the ones that have the responsibility of patient education.
