Abstract Sickle-cell disease is a genetic disorder that results from the abnormal structure of red blood cells. The peculiar shape of the red blood cell prevents the normal absorption of oxygen. This disease results from the abnormal production of hemoglobin S (HbS). Therefore‚ a mutation in this gene causes a lower supply of oxygen to the cells‚ which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit

Essay: Why Is Stem Cell Research so Controversial? In 2001‚ President George W. Bush cut funding for research on stem cell obtained from human embryos because it is technology that requires the destruction of human life "My position on this issue is shaped by deeply held beliefs. I also believe human life is a sacred gift from our creator" (Bush‚ George W.‚ Crawford‚ Texas‚ Thursday‚ August 9‚ 2001. Stem cell research speech.) His policy restricted the government funding of stem cells. These are utility

Cell Phones and Driving One of the most popular innovations in automotive travel in the past decade has nothing to do with the automobile itself‚ the people who drive them‚ or the roads over which they operate. Rather‚ it is the ability to carry on telephone conversations while driving. A major concern for the National Highway Transportation Safety Administration (NHTSA) is that drivers are being distracted by cell phone usage and about 85 percent of the nation ’s cell phone subscribers

2001‚ the federal government authorized stem cell research. There has been much controversy revolving around this type of research‚ especially the embryonic stem cell. Do you agree or disagree with the stem cell research. Why? Stem Cell Research is the process in which scientists use human cells in order to create new cells‚ examples including brain‚ nerve‚ liver cells‚ and some tissues. Stem cell research includes embryonic stem cells and adult stem cells. Although the research can be medically beneficial

discovered the endless possibilities of the so called embryonic stem cells. It has been said that these cells have the ability to repair an entire tissue or even create a copy of it. It is also said to be a potential cure for innumerable serious diseases such as the Alzheimer and the Parkinson’s disease. This is why stem cell research should definitely be funded for the enormous impact it can make in the medical field. Stem cell research is perhaps one of the most controversial topics in modern day

contemporary biological issue Introduction Stem cells are undifferentiated cells able to differentiate into specialized cell types. These are used for stem cell treatment‚ which is an intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury. For over 30 years‚ bone marrow and‚ more recently‚ umbilical cord blood stem cells have been used to treat cancer patients with leukaemia and lymphoma because during chemotherapy most growing cells are killed‚ but a donor’s
