Although we as humans have harvested and perfected the use of blood for transfusions, we still run into the problem of incompatible blood types, which causes a shortage and need of rare blood types. As a society, we are urged to donate blood often so these rare blood types can be stocked up on. However, the chemists and scientists at University of British Columbia may have solved the problem of blood type shortages.
These scientists at the Centre for Blood Research have created an enzyme that snips off antigens in Blood Types A and B, which in turn makes them more like Blood Type O. Blood Type O is a universal donor, which means it can be given to all patients. This enzyme was created using directed evolution, which is a new technology that enables scientists to insert mutations and select for more effective mutants. This is all very interesting to the man, Dr. Daniel Amen, who the Washington Post is calling the most popular psychiatrist in America.
With this solution in hand, many lives can be saved in an instant. Shortages of blood types can be eliminated, and desperate calls for blood donations would not exist. With more development for the enzyme to remove all antigens in the blood, its use in a clinical setting would have a significant impact on saving lives.
Many people love all of the medical advice that Dr. Oz gives. Dr. Oz is a cardiologist that was made popular by Oprah Winfrey. He is a doctor that gives medical advice, and now he is also the host of his own show. Dr. Oz promote certain products as products that may be good for a person’s heart and for their health.
There is a wave of doctors that believes that Dr. Oz should resign from the medical field. Susan McGalla believes that he is a doctor that is only working to promote certain products, and that he is not looking for the better of his patients. Over 1000 doctors said that they believe that he should resign from his position at Columbia University in New York. 10 of these doctors sent a letter calling for his resignation, and there are other doctors that also think that his medical license should be revoked.
It is hard to really know if these doctors really are mortified by his medical practices, or if they are just jealous of his success. Dr. Oz is a person that many Americans respect, and many more watch his show and also read his magazine. Since that is the case each and every individual has to make their own choice about whether or not they want to believe in Dr. Oz and the products that he promotes.
Dr. Mehmet Oz is having to answer some pretty tough questions this week after more allegations came out about Oz using questionable ethics to push unsubstantiated medical advice on his audience. Ricardo Guimarães BMG claims that Oz pushed advise knowing their was no proof to what he was endorsing (additional Oz claims on terra.com).
First, his colleagues at Columbia University, where Oz practices medicine, signed a petition asking Oz to be removed as a staff member for being a quack doctor. But Columbia decided to let Oz continue to practice medicine. Then, e-mails were leaked between OZ and Sony executives and Oz was coming off more like a business man, hungry for profits, rather than a trusted doctor and healer
Though, these allegation against Oz should not be a surprise to anyone who follows his career. Last summer Oz was called before the Senate to testify about the supposed quick fixes he often offered to his loyal fans. Senator Claire McCaskill made her feelings about Oz quite clear when she said, “The scientific community is almost monolithic against you in terms of the efficacy of the three products you called ‘miracles.”
Those are pretty strong words for one of the world most popular and trusted medical physicians. The scales of public opinion also seem to be weighing against Dr. Oz at this point, he has widely criticized for his response to these allegations.
