Substitutes like adult stem cells and somatic cell nuclear transfer from placental or umbilical cord stem cells of newborns. Adult stem cells, however, were found to be nearly not as malleable as human embryonic stem cells or those acquired through somatic cell nuclear transfer. These were found good for reproducing red and white blood cells and platelets, but not for replacing neurons, muscle or organ tissue. On the other hand, somatic cell nuclear transfer from the placental or umbilical cord stem cells of newborns tended to be rejected by the body and developed immune reaction problems (Dobson).
Conclusion unanimous opinion on the ethics of conducting embryonic stem cell research may not be possible in a pluralistic society, such as that of the United States, but a consensus may be reached (Kukla 2005). The Commission offered the consensus that embryos are not human persons but possess full rights and interests and deserve respect as a form of human life. The potential medical and scientific benefits of the research are so huge that a reconsideration of the way respect is shown to the embryos as symbols of human life is urged. There are views that donating embryos shows respect by using them to enhance the lives of sufferers. Other research advocates also believed that funding the research would also show respect by allowing the use of stem cells, which have not yet developed into cell lines, to be used for humane purposes (Kulka).
Many otherwise terminal or incurable and life-threatening conditions may be cured by embryonic stem cell research (Kulka 2005). Research should be viewed as aligned with the mandate for respect and in the light of an absence of suitable...
For example, in the case of sickle beta thalassemia, the individual has inherited a gene for hemoglobin S. from one parent and a gene for beta-thalassemia from the other. Or, in the instance of SC disease, the individual has inherited a gene for hemoglobin S. from one parent and a gene for hemoglobin C. from the other. The sickle cell trait in heterozygous carriers confers the resistance to malaria phenotype
These crises are a direct result of way in which the deformed red blood cells adhere to both each other and the insides of the blood vessel walls, blocking tissues from receiving oxygen. The disease is prevalent across some parts of Africa, the Middle East and India, which is due to the way in which the heterozygous form of the condition offers carriers a degree of protection against malaria,
Sickle Cell Anemia There are both advantages and disadvantages of having sickle cell anemia. How much benefit a person gets from sickle cell anemia's advantages, however, largely depends on where that person is located and what his or her environment is. The same concept applies to the disadvantages of this condition, although to a lesser extent. The root of the advantages and disadvantages of this disease pertain to its specific form
Sickle Cell (Rough Draft) Sickle cell anemia is a blood disease that causes badly formed red blood cells. The disease is genetec. Mostly people from Africa or other coutries around the Mediterraean Sea get it. In the United States, African-Americans are most likely to have it (Howard, 1995). Red blood cells are the blood cells that carry oxygen throughout the body. When a person has sickle-cell anemia the hemoglobon in the cell
Sickle cell anemia according to the U.S. National Library of Medicine/National Institutes of Health - NLM/NIH (2013), "is a disease in which your body produces abnormally shaped red blood cells." As the NLM/NIH further point out, the cells produced in this case ordinarily have a crescent-like shape. The red blood cells of an individual usually have a disk-like shape. It is this disk like shape that enhances and eases their
Sickle Cell Anemia As an inherited condition, it is presence of hemoglobin which tends to be abnormal that brings about sickle cell anemia. In basic terms, hemoglobin is a red blood cell protein whose main function is carrying oxygen. It is this hemoglobin abnormality that informs 'sickled' or distorted red blood cells whose survival is compromised as a result of the distortion and fragility. Though the prevalence of the condition largely
