Circulation) “From Stem Cells to Viable Autologous Semilunar Heart Valve.” Results of heart valve replacement surgery are complicated by the morbidity associated with lifelong anticoagulation of mechanical valves and the limited durability of bioprostheses. This problem may be addressed by providing living, autologous biological structures which do not require anticoagulation, yet retain the capacity to remodel and repair, obviating the need for late valve replacement. Mesenchymal stem cells (MSCs) were

considerable amount of interest recently. A fingerprint is a physiological feature of an individual that uniquely identifies the person based on fingerprint ridge and valley pattern (Jain and Maltoni, 2003). As fingerprint is the main focus of this research, it is discussed elaborately in following

In the World War 1 and World War 2 there were many technological and scientific advancements. Unfortunately, many people died because of these advancements. Usually, the improvements were to defend themselves from other enemies. The first inventions lead to other better inventions and feed the hunger of being the best in scientific and technological areas. These inventions were very big and left a mark in the world’s history. But, are these wars a necessary evil so that the society create bigger

Going to get tested for a genetic disorder? That’s so yesterday; thanks to modern scientific knowledge, direct to consumer (DTC) tests make going to a medical professional unnecessary for genetic testing. Medical professionals should not be required for all genetic testing, since the requirement of such professionals raises questions of ethics regarding abortion and eugenics, issues which restrict the rights of parents to make decisions that apply to themselves and/or their offspring. However, regulations

transplant can be taken within the animal embryos and place it with human cells. Since, this types of cells are stem cells that can differentiate into many cell types, which allows generates functioning human organs. However, some people argue that taking modified human genes and placed it in the DNA in pig or sheep embryos should not happen, as it would appear to have a sense of human characteristics. Thanks to a stem cell researcher, Hiromitsu Nakauchi, at Stanford University and the University

This lab was conducted for the purpose of answering any last questions we, as a group, had about cells. We asked our question, whether different types of dyes affected specific cells in different ways, because we had only used one dye on each cell in the past, and we hadn’t got to see the true difference that each individual dye had on each cell. We hypothesized that if we dyed a specific type of cell different colors then we would see different things because there would be a different chemical reaction

Personally, I would like to have my DNA mapped because I find DNA interesting and it may uncover explanations as to why I am the way I am. It explores my background as a human being and where I came from. Even the process of gathering DNA is relatively simple. But since I am a broke college student with no extra money, I can’t say I would pay any more than $50 to have my DNA mapped out. Even though DNA mapping unveils previously unknown data about your past, it should be regulated. Without regulation

cloning, and how to fix this controversial issue. Cloning is a cell or organism that is genetically identical to the unit or individual from which is was derived from. Cloning can be done on animals, plants, food, and even humans. The three types of cloning are Gene, Reproductive, and Therapeutic Cloning. Gene cloning creates copies the DNA, Reproductive cloning involves copies of animals, and Therapeutic cloning deals with stem cells in human beings body. One of the pros from cloning is that it

raised some heads, as some are against it because they believe it’s playing God. Human Genetic engineering has been viewed as a way to cure hereditary diseases. There are over 3,000 diseases as a result of a genetic disorder. Conditions such as sickle-cell anemia, Tay-Sachs disease, Duchenne muscular dystrophy, Huntington's

“Cracking Your Genetic Code”, a NOVA documentary, reveals the idea that the human race stands on the verge of a major revolution. In this, we are given insight into the life of a now fully functional celled cancer survivor and a cystic fibrosis sufferer who now obtains healthy breathing patterns. So, what caused such a drastic turn of events? In these cases, genetic mutation pushed the teens to near death. Their cure, however, involved a different technique: genetic coding. Also known as the scientific
