Executive Summary:
Sickle cell anemia is a disease that is caused by abnormal hemoglobin. The abnormal hemoglobin syndicates with other abnormal hemoglobin molecules to cause rigid distortion of red blood cells. HbF or fatal hemoglobin is a crucial modifier of the severity of sickle cell anemia. An organism was produced that yields a high concentration of HbF, which is used to help treat sickle cell anemia. To determine the organism, total protein was isolated and an enzyme analysis was preformed using spectrophotometry, sequences of the strains were analyzed to conclude which stain produced beta-galactosidase under various nutrient conditions, and cells were observed with and without plasmids
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.
Traits get passed down from one generation to the next through Meiosis (cell division), where each parent gives you one Gene for each trait.
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 anemia is a hereditary disorder that mostly affects people of African ancestry, but also occurs in other ethnic groups, including people who are of Mediterranean and Middle Eastern descent. More than 70,000 Americans have sickle cell anemia. And about 2 million Americans - and one in 12 African Americans - have sickle cell trait (this means they carry one gene for the disease, but do not have the disease itself).
Sickle Cell Disease is an autosomal recessive genetic disease that occurs due to a mutation in the β-globin gene of hemoglobin. Autosomal meaning that it is not linked to a sex chromosome, so either parent can pass on the gene to their child. This mutation is a result of a single substitution of amino acids, Glutamic for Valine at position 6 of a β globin chain. The presence of this mutation causes
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
According to the 2016 edition of the Oxford dictionary, to define someone or a group of people as vulnerable means that they are susceptible to physical or emotional harm (Vulnerable, 2016). One of the most recognized populations of vulnerable people are children; furthermore, by adding an inherited disease process, that decreases the immune system, would only increase the vulnerability of the population. Children with sickle cell anemia are highly susceptible to being attacked both physically and emotionally by foreign invaders that threaten their already fragile immune systems. During the process of “making hemoglobin, which carries oxygen in our red blood cells, a defect can occur when the amino acid glutamate is replaced by valine. This simple substitution can cause the red blood cell to sometimes collapse, assuming the characteristic sickle shape. The red blood cells, normally very elastic and able to conform to the shape of tiny capillary blood vessels, become rigid and can block the blood vessels, depriving tissue of oxygen and resulting in severe pain” (Stone, 2015). Sickle cell children must endure an incredible amount of pain, many hospitalizations, a pain management regimen, and the inability to experience the normal, everyday life that most of their peers participate in each day. Health care for sickle cell children is focused toward management because there is no cure and as their bodies run out of healthy red blood
Sickle cell disease (SCD) occurs in 1 out of every 365 African American births compared to 1 out of 16,000 Hispanic-American births (1). SCD is a group of red blood cell disorders in which patients have a sickle or moon-shaped red blood cell due to an abnormal S hemoglobin. While sickle cell disease is relatively rare in American births, this is an alarming statistic among people of Sub-Saharan (west and central) African descent. An interesting fact is that SCD occurs more often among people from parts of the world where malaria is or was common, such as Sub-Saharan Africa (1). In addition, it is believed that people who carry the sickle cell trait are less likely to have
Sickle-cell Anemia is a genetic disorder that causes sever pain in the lower back, legs, arms, abdomen, and chest. Red blood cells carry oxygen to the body. The body uses oxygen to make energy. Inside the red blood cell is a protein called hemoglobin, which hooks on to the oxygen. People with sickle-cell anemia have abnormal hemoglobin known as hemoglobin S. Hemoglobin S changes the blood cells into the shape of a sickle. These abnormal sickle cells stick to the blood vessel walls causing blockages. These blockages do not allow blood to flow. This is what causes the pain. People get sickle cell disease when a parent has a mutated hemoglobin gene. Their child has a chance of inheriting the sickle-cell trait or getting sickle-cell Anemia.
Discussions in regards to race can be fraught with extreme opinions, to examine this subject in a more dispassionate light it is helpful to first define the terms. Race is distinctly different from ethnicity or culture, but is often combined in both writing and thought. From a biological perspective, the description of race in human populations is meaningless, but examined from a cultural basis it can make an enormous difference to a population’s wellbeing, or survival, based solely on their difference in morphology.
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 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 disease majorly affects the hemoglobin that is present in our blood. The job of hemoglobin is to help transport oxygen and carbon dioxide to and from the cells throughout our body. Hemoglobin is present specifically in our red blood cells. Each red blood cell contains two hundred and eighty million hemoglobin molecules. Red blood cells normal shape is a biconcave shape because of the lack of many organelles and a nucleus. The shape is so important to a red blood cells functioning that if it is not shaped normally it has major consequences. The shape helps them to fit through capillaries easier and also allows for an increased surface area which results in easier gas exchange. Sickle-cell disease is a genetic disease that causes issues in the oxygen/carbon dioxide carrying hemoglobin molecules that are present in our red blood cells.
Sickle cell anemia is an anemia that is inherited and mostly affects people whose heritage can be traced back to places where malaria was prevalent. There are approximately 100,000 Americans that have the disease and many more with the trait. Several of my family members are afflicted by this medical condition that causes red blood cells to take on an irregular shape.
