preformed anti-donor antibodies. It is characterized by the binding of these antibodies to antigens on vascular endothelial cells. Complement activation is involved and the effect is usually profound. Hyper-acute rejection happens within minutes to hours after the transplant procedure. Unlike hyper-acute rejection, which is B cell mediated, acute rejection is mediated by T cells. It involves direct cytotoxicity and cytokine mediated pathways. Acute rejection is the most common and the primary target

restoring, and growing that makes cells, organisms, ecosystems and genomes resilient to damage. “Grow your own... heart, limb, or organ" is about research that is being conducted on the flatworm known as planaria. They have the ability to regrow their head or tail in as little as one week when damaged or cut off. Scientists are studying these worms in an effort to learn how to grow a new pancreas, new neurons, and other body parts. The researcher hopes this research will be an effective way to combat

know can produce 30,000 pounds of milk. Take its clone, and if you do this, this and this, you'll expect 30,000 pounds of milk. You'll know ahead of time what the production is going to be." (Michael Bishop) Also, cloning plants would be useful for research on biofuel, and even herbs. A cloned plant can yield a thousand new plants from one parent plant. This means that farmers can produce more crops without a lot of seeds.Any cloned plant would come from one parent plant. This would mean that farmers

Intro Human chimera research is a controversial field of science that involves the introduction of human embryonic stem (hES) cells or human neural stem cells into nonhuman animals, thus creating a human-animal interspecific chimera. With the promise of significantly enhancing health and possibly curing some of the most deadly diseases, humankind has mitigated diverse ethical issues associated with stem cell research. However, the use of human stem cells to create chimeras has generated unusual ethical

The principle of utilitarianism the moral test for the rightness or wrongness of an action. It is based on the principle of utility, aiming to maximise pleasure and minimize pain. The word utility comes from the Greek “utilis” meaning beneficial/useful theory. It is a teleological consequential argument, as everything is focused on the end result and whether or not it generates happiness. It is relative to the situation as can bend the rules, allowing hedonistic acts to occur, hedonistic acts are

Tissue Research The use of fetal tissue in biomedical research has been a hot topic for debate in social and political forums ever sense the landmark decision in the 1973 case of Roe vs. Wade (Beller & Weir 182). The decision of the Supreme Court to give women the right to abort a fetus without having a medical reason for doing so, sparked controversy which has affected any medical procedure or research dealing with fetuses (Bellar &Weir 182). Supporters of fetal tissue research believe

The Next Generation of Cloning Hundreds of countries around the world are scrambling to ban human cloning, but scientists are convinced cloning can be useful in the near future. Cloning is making a replica of an organism or a cell, a copy of a human or mammal and making two or more of them. There have been a majority of people that have appealed to cloning and whether human beings should not be cloned nor should cloning be used. There has been many reasons for whether cloning should be allowed or

The following is a modified version of the AMCAS MD/PhD essay. Biomedical research has been an interest of mine for as long as I can remember. The concept of tackling and solving biological mysteries has always been greatly appealing to me and I found the fact that work done on something as microscopic as cells and proteins could be used to cure visible ailments of disease to be astounding. Throughout my primary education, I relished each opportunity to conduct experiments in class, and I eagerly
