Xenotransplantation, Transgenics, and the Animal-human Boundary
The progression of modern science and technology has often challenged old, time-worn notions. Nowhere does this seem truer than in biology and medicine, as these fields have changed drastically in recent decades and also relate so closely to the actual substance of how people live. One such development is what is called xenotrans-plantation or the transplantation of organs or cells across species—particularly notable when from a non-human species into a human. The very fact that the procedure is possible is telling as regards the inherently ephemeral nature of the distinction of humans from other animals. It may be useful to first outline how xenotransplantation works, however.
Many ailments can be cured or at least ameliorated by the replacement of an organ and the progression of medical science has increasingly allowed more types of organs to be successfully transplanted. Doctors’ ability to transplant is thwarted, however, by the disproportionate number of patients in need of such life-saving treatment relative to the number of donor organs available. Due to a variety of circumstances there just aren’t enough spare organs to go around. In light of this situation and the ever increasing number of people who die every year while waiting for an organ donor, xenotransplantation has become a very attractive alternative to human transplants, for obvious reasons. While there may be a shortage of human organ donors, we can easily envision animals being bred for their organs and providing an almost unlimited supply.
The major practical issue to be surmounted with any transplant is immunological. For a transplant to be successful the transplanted tissue must not...

In America, there are currently 122,198 candidates on the Organ Procurement and Transplantation Network (OPTN) waiting list (“OPTN”). Due to a lack of available organ donors, around 18 waiting list candidates will die every day (“OPTN”). This has prompted the development and investigation of xenotransplantation—the transplantation of animal tissue and organs to potential human candidates. Currently in its early phases of development and study, xenotransplantation is controversial for its high failure rate, with only a few cases successful. This is attributed to the human immune system rejecting those animal donated organs, thereby potentially causing immediate death to the human candidate. On the one hand, pre-clinical trials have broadened the understanding of the human immune system, as well as furthered xenotransplantation research. However, because xenotransplantation has achieved little success, opponents of the procedure argue that it is unethical to continue its practice. It is also important to note that trials often use baboons in place of humans, which presents several variables to be examined before further human trials can begin. Moreover, the potential acquisition of zoonotic infection is a serious risk that cannot be fully determined without the use of human subjects. Thus, not only will xenotransplantation require more extensive study, it will also require hundreds of animal lives, all in an effort to create nothing more than a last resort.
College student drunkenness is far from new and neither are college and university efforts to control it. What is new, however, is the potential to make real progress on this age-old problem based on scientific research results. New research-based information about the consequences of high-risk college drinking and how to reduce it can empower colleges and universities, communities, and other interested organizations to take effective action. Hazardous drinking among college students is a widespread problem that occurs on campuses of all sizes and geographic locations. A recent survey of college students conducted by the Harvard University School of Public Health reported that 44 percent of respondents had drunk more than five drinks (four for women) consecutively in the previous two weeks. About 23 percent had had three or more such episodes during that time. The causes of this problem are the fact that students are living by themselves no longer with parents or guardians; they earn their own money; students need to be a part of a group, be accepted; and they have the wrong idea that to feel drunk is “cool.”
The case at hand is whether or not we should use xenotransplantation in humans. It is a rather controversial topic that has brought up strong feelings in parties on both sides of the argument. One of the main arguments of the people who are for xenotransplantation is that there is a large shortage of organs available for transplant, and that animal organs could provide enough spares to satiate the need. A recent figure given by the FDA is that currently 13 people die per day in the U.S. because of the lack of organs available for transplant. Meanwhile, one of the arguments of those people against xenotransplantation stems from animal rights. Some people feel that it is wrong to use animals in such a way and that there is a great potential for animal abuse.
Healthcare-associated infections (HAIs) have been a persistent problem in the United States for decades. Yang et al. (2013) stated that “Nosocomial infections or healthcare-associated infections are defined as a localized or systemic condition resulting from an adverse reaction to the presence of an infectious agent or its toxin. There must be no evidence that the infection was present or incubating at the time of admission to the acute care setting” Also if infections occur within 48 hours of being discharged from the hospital or a healthcare setting, then it is considered as a healthcare-associated infection (Daud-Gallotti et al., 2012). Healthcare-associated infections can be easily prevented, however they are held accountable for hundreds of thousands of deaths for the past few decades. They have been known to increase rates of drawn-out hospital stays, cost, morbidity, mortality, and readmission to the hospital (Montoya & Mody, 2011). When antibiotic-resistant organisms (AROs) are involved with these types of infections, the rates are expanded even further and usually cause many more fatalities (Srigley, Lightfoot, Fernie, Gardam & Muller, 2013).
To understand why alcohol is a problem for college students, I decided to survey a random sample of 26 students here at State U. I designed the survey to be a quick and effective way to obtain the drinking habits of college students in order to discover where possible alcohol problems may arise. I chose to survey a random sample of students in order to get a complete response from older students as well as some of the younger students.
Statistics show that 80 percent of college students drink alcohol, with half of that number drinking heavily or binge drinking regularly. This leads to academic problems for the

What is the goal of technology? Most answers include some form of ways of increasing speed, or decreasing size all for the ultimate goal of convenience. Ok, so what is convenience? Convenience is the skill level at which something can be achieved, in other words, how desires can be met. So the true goal of technology is to assist in meeting desires. The quicker and smaller technology is, the easier it is to obtain those desires. Nanotechnology is the newest wave of technology that will potentially make a huge breakthrough in technology’s goal. Though not a science secure as of yet in our world, it is waiting for the time to make its momentous break though into the modern world, bringing with it a global effect on the human way of life.

The current issue facing societies around the world is human-animal hybrids experiments. These experiments are viewed in two lights, positive and negative. The positive of having these tests are that scientists could rid the world of diseases. However on the other hand people see these studies as inhumane and detrimental to everyone’s well being. This paper will be broken down into 6 areas including (1) a brief history of hybrid experiments dating within the decade, (2) a view of the stakeholders in the issue at hand, (3) how people would interact with humans receiving these treatments, (4) cultural and ethical considerations, (5) problems still at hand, and (6) a conclusion.
