Essay On Aplastic Anemia

Sickle Cell Anemia is a group of disorders that cause red blood cells to become misshapen and break down. Sickle Cell Anemia affects many people all over the world; Sickle cell disease is the most common inherited blood disorder in the United States, affecting 70,000 to 80,000 Americans (Ashley-Koch, Yang and Olney). Sickle Cell Anemia causes your red blood cells to be thin, stiff, and shaped like a sickle. But your red blood cells are supposed to be round and soft. When a person is diagnosed with sickle cell anemia the blood cells start to become clogged blood vessels, which can cause a great amount of health issues including: infections, stroke, and acute chest syndrome. People get sickle cell anemia by inheriting a mutated gene from both of their parents. On the down side, there is not currently an effective cure for sickle cell anemia, there are several different therapeutic approaches to treating and attempting to cure the disease and help people who are affected with sickle cell anemia better manage their symptoms. There have also been several great scientists that dedicated a lot of research to help find a cure for sickle cell anemia.

Anemia is a disorder of the blood. It occurs when your body does not produce enough erythrocytes or red blood cells (RBCs). Without the erythrocytes oxygen can not be adequately delivered to the tissues and organs throughout the body. This will cause you to become weak and tired. A person may also experience headaches, skin pallor, and faintness. Your body may attempt to compensate for these symptoms by speeding up the heart rate and respiratory rate. This is the body’s attempt to return oxygen levels to normal(Thibodeau and Patton, 2005).

Iron Deficiency Anemia affects millions of individuals across the world. This disease strikes many more women than men and has harmful effects on all who suffer from this deficiency that causes oxygen-carrying capacity to decrease. The causes can vary amongst different groups, but the aggravating symptoms remain constant. Much of the research on Iron Deficiency Anemia concentrates on not only the treatment of this disease, but also the prevention of it. To attain a better understanding of how to treat this problem, one must clearly know what Iron Deficiency Anemia means, what causes this disease, the effects of it, and finally how to cure it.

Sickle Cell Disease is an illness that affects people all across the globe. This paper will give a description of the sickness through the discussion of the causes, symptoms, and possible cures. Sickle Cell Disease (SCD) is a "group of inherited red blood cell disorders."(1) These disorders can have various afflictions, such as pain, damage and a low blood count--Sickle Cell Anemia.

Sickle cell disease is a disease that is most prevalent in people of African descent along with people of Mediterranean and Middle Eastern origin. This disease is known to affect about 70, 000 Americans and about 2 million people carry the trait (meaning that, they carry a single gene mutation).

Leukemia is cancerous disease that starts in blood-forming tissue such as the bone marrow and causes large numbers of blood cells to be produced and enter the blood-stream (National Cancer Institute, 2008, para. 1). It is one of many complicated cancer diseases that affect all ages and have very negative outcomes if not treated properly, and on time. Within the disease are several different types that affect according to how quickly the disease develops and attacks the body. It could be classified as chronic leukemia, which has a slow progress of getting worse or acute leukemia which usually gets worse quickly. The types of leukemia also can be grouped based on the white blood cell that is affected (National Cancer Institute , 2008, p. 1).

When Malaria is present and infects red blood cells, parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population, allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase. When a population is effected by disease or other circumstances, allele frequency may decrease or change. HbA (normal hemoglobin) and HbS (defective hemoglobin) have varying frequencies and while the HbS gene is present in populations it is

The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin's, Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged. This is what causes the problems of sickle cell disease.

Sickle cell anemia is caused by a defect in the gene that controls the production of normal hemoglobin, which is an iron-containing protein in red blood cells that transports oxygen from the lungs to body tissues. The defective gene results in the production of abnormal hemoglobin known as hemoglobin S. If you have the disorder, you inherited one gene for hemoglobin S from each of your parents. The gene is recessive, so if you received a copy of the gene from just one parent, you are a carrier of the sickle cell gene.

Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes, when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications, or have a pattern of ongoing problems that shorten their lives. The most common and serious complications of sickle cell disease are anemia, pain, fatigue, and organ failure. Today there are many alternatives and opportunities that a sickle cell patient may consider. One outlined in this paper is the Hydroxyurea method.

Sickle cell anemia is a genetic blood disorder that is caused from the abnormal function of hemoglobin. In the case of sickle cells anemia, the hemoglobin molecule in red blood cells is sickle- shaped leading to the blockage of blood flow to blood vessel of the lungs and other organs and therefore a very slow transportation of oxygen. It mostly affects people with African descents with an affected population of 0.25% in African Americans. It results from a mutation at the sixth codon of the beta globin gene (HBB gene) in which the amino acid glutamic acid is substituted for valine, leading to the production of an altered form of hemoglobin S (hbS).

A rare blood disorder in which the bone marrow does not produce enough Red Blood Cells. Without enough production of Red Blood cells your body cannot carry Oxygen efficiently, it also cannot remove carbon dioxide from your body through the lungs, like it should.

Leukemia is something that we hear about a lot. I believe that people do not understand exactly what leukemia is and how dangerous it can be, I chose this topic to try to help them understand. In this paper I will explain what leukemia is and what treatments you can choose from to treat the cancer.

Cancer, a long and difficult journey assimilated with death. Cancer, in general, is when cells begin to grow out of control and can start anywhere in the body. There are many different forms and types of cancer; scary but true. All forms of cancer is terrifying, but the most terrifying for children is Leukemia. Leukemia is the most common form of cancer in children and teens. It zones in on blood-forming cells, mainly white blood cells, in the bone marrow. This form of cancer accounts for almost one out of three cancers (Leukemia in Children). Why, in my opinion, this is the most intimidating form of cancer is because it takes the lives of the young who had so much potential and barely began to live their own lives. It takes those who are

Cells were infected with the lentivirus, and they were selected by puromycin, finally there different cell clones were picked.1
