Ghost Hearts Doris A. Taylor, inventor/creator of the ghost hearts constantly harvest organs from the newly dead by re-engineering them. Doris is the director of the regenerative Medicine Research for the center of Cell and Organ Biotechnology at the Texas Heart Institute. Dr. Taylor worked on methods of decellularization and in 2008 she perfected the method. Decellularization is taking all the cells out of the organ leaving it with the lipids, sugar, and proteins. Ghost heart or a ghost-like…

Mechanical Heart valves are designed to mimic natural heart valves as closely as possible. The valve is implanted in the heart of the patient where the damaged heart valve was removed. Artificial heart valves allows for correct blood flow through the heart by opening and closing with each heartbeat (St Jude Medical, n.d.). The Medtronic mechanical heart valve contains two leaflets (Medtronic, 2011). The pressure in the heart causes the leaflets to open and close, allowing blood flow in only…

the heart from the body is pumped from the right side of the heart through the pulmonary artery to the lungs and to the left side of the heart then back out to the rest of the body with oxygenated blood and the cycle repeats. In TGA, deoxygenated blood returning are not going to the lungs to be oxygenated, but is pumped back out to the body. This happens because…

Mechanical heart valves provide their greatest benefit by replacing a fatigued natural valve with a prosthesis that was specifically engineered for the variety of patients who experience heart valve disease, thus relieving the patient of most associated conditions and improving their quality of life. However, throughout the last half century there have been many cases of structural failure and induced conditions such as thrombosis due to the materials used in these devices. Through the many case…

The Edwards SAPIEN heart valve is a collapsible aortic heart valve that can be introduced into the body via a catheter-based delivery system. The valve is designed to replace a patient’s diseased aortic valve without traditional open-heart surgery and while the heart continues to beat. The valve can be implanted in patients using the fransfemoral technique meaning delivered thorough the femoral artery or trans-apical technique meaning delivered via a small incision between the ribs. Prior to…

Heart murmurs are constantly diagnosed in people, but what do heart murmurs do? Does it harm the host? It all depends on the type. From there, we dig deeper. According to http://www.madsci.org/posts/archives/1999-08/933633819.Me.r.html, Heart murmur is the sound that is made because the blood passing through the heart’s valves and chambers make a sound. Sometimes, the valve doesn’t open entirely, and the blood goes back to the chamber it just left. When that happens, it makes a swishing noise,…

“Government is best which governs least” according to the article “Civil Disobedience,” by Henry David Thoreau. In this article, Thoreau also mentioned that he believes that government is best when it governs not at all. However when a government governs not at all, then there exist chaos and war. But a government that governs least is a government that many people will agree is the best type of government. This type of government allows people absolute freedom. Not freedom per say, but…

belief citizens are in danger of losing individual rights as a result of the CCW…

Being able to use gun for self-defense or protection is a right which can 't be denied to U.S citizens; however guns are not the only weapons available to serve the same purpose. Since guns are made to kill, one should consider alternative measures of protection out of respect for life. The statement made by Hasselstrom’s in her paper, is somewhat valid, but comes off as a very one sided opinion if regards to “gender equality” claiming that barring arms makes men and women equal. There is a…

have the same rights as us humans? If you think about this, passing a Bill of Rights for animals could go against centuries of human culture, increase the cost of food, hinder medical research, and may cause other problems. I believe that animals should not have a Bill of Rights. My first reason is that such a law would go against human culture because we as people run the world. Can animals even work, cook, clean, or even talk, think about it. Giving animals the same rights as we have…
