Lethal Infection: An Experimental Study
More recently, researchers have begun to make progress on understanding the mechanisms that create resistance to the lethal infection. About one out of ten African-Americans has the sickle cell mutation; are known not to develop sickle cell anaemia, leading rather normal lives. However, researchers found that these individuals, who are said to carry the sickle cell trait have an advantage (heterozygous advantage) over people who carry no copies of the sickle cell allele. A single copy of the sickle cell allele increase resistance to malaria

    Sickle cell anemia affects people with African, Mediterranean, Middle Eastern, and Indian ancestry (Scientific American). Sickle cell anemia occurs when a person inherits two sickle cell gene, one from each parent, that cause the red blood cells to change and become crescent shaped. The underlying problem involves hemoglobin, a component of the red blood cells. Hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lung. In sickle cell anemia, the hemoglobin is flawed (The New York Times). As a result, the cells become sickle shaped and can’t travel as easily through blood vessels. Sickle cell anemia is an illness, which has one primary cause, but a variety of symptoms and treatments (Scientific American.) Like some illnesses, sickle cell anemia has one primary cause. In order for sickle cell anemia to occur is when a sickle cell gene have, been inherited from both the mother and the father, so that the child has two sickle cell gene. The sickle cell gene causes the body to make abnormal hemoglobin. As mentioned above, hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs. A person with normal red blood cell will have hemoglobin A; however, a person with sickle cell disease will have hemoglobin S…

    Anthropology 1AA3 Assignment 1

    Cultural and biological anthropologists have observed that people from India, Asia, and the Mediterranean have a higher percentage of people with one abnormal hemoglobin allele, compared to in other parts of the world where most people have two normal hemoglobin alleles. It's been found that people with two abnormal hemoglobin alleles carry a disease called sickle cell anemia; this disease is known to be circumstantially fatal. In addition to this finding, there's a direct correlation between the number of people in an area where the sickle cell trait is common and the amount of people with the one abnormal allele that proves to shield the infection of malaria. This single abnormal hemoglobin allele is known as hemoglobin S, Allison (1990) was first to examine that when hemoglobin S is present, people seem to be less resistant and protected against malaria. Her research in The Anthropology of Infectious Disease helps in further understanding the connection between a cultural environment where a certain disease (malaria) is most present, and how biologically people of the surrounding community anatomically adapt to fight off the condition. Natural Selection (Peters-Golden,H. 2010), the idea of how anatomical changes are largely due to favored adaptations for proficiency of survival in a given environment, can further prove why people in areas more prone to sickle cell anemia…

    Sickle Cell Plan of Care

    Sickle cell anemia is the most common form of sickle cell disease which is an inherited, autosomal recessive disorder that causes an abnormal hemoglobin cell. The person with this specific disorder inherited hemoglobin S from both parents, also known as homozygous (Lewis, Dirksen, Heitkemper, & Bucher, 2014, pp. 644-647). This hemoglobin S results from the substitution of valine for glutamic acid on the B-globin chain of hemoglobin, and this ultimately causes the erythrocyte to stiffen and elongate taking a sickle shape in response to low oxygen levels (Lewis et al., 2014, pp. 644-647). Due to the sickle cells elongated shape, and its stiff and sticky consistency it tends to get stuck in capillaries and vessels, and blocks blood flow to limbs and organs (Lewis et al., 2014, pp. 644-647). The major problems with sickle cell anemia is due to their sickled shape, reduced life expectancy and their ability to carry enough hemoglobin or transport it properly to…

    The guests at the party will have got food poisoning from the salmonella in the uncooked burgers. The reason they got food poisoning is because the inside of the burgers weren’t cooked enough or properly so the bacteria didn’t get killed inside the burgers. The burgers would have you be cooked at above 170 degrees Celsius, and as the heat didn’t kill the bacteria, it entered the body. As Chloe’s dad only cooked the burgers on a high hear for a very short amount of time, he burnt the outside without heating the inside of the beef burgers.…

    INTRODUCTION: “Pain” sudden or chronic, lasting from a few hours to a few days; from a few weeks to a few months evolving from an adhesive substance in red blood cells. The “Pain” is inherited by an retriction blood flow through the body do to an abnormality in the cells. “Sickle Cell Anemia” a chronic illness discovered in 1910 by an American physician named James Bryan Herrick. Sickle Cell is more that just pain; it is a disease that is affected by abnormal blood cells that has an adhesive formation causing the natural flow to be compromised. As a result, these abnormal cells become fixed in the blood stream and not flowing to major body organs causing extreme pain and even a stroke. Why is this process painful? Have sickle cell patient become tolerant to pain or is it because some of them handle self-care management? For many years there has been a link between Sickle Cell Anemia and Pain caused by the stickiness of the blood cells. When this occurs, it decreases normal blood flow to the major organs causing strokes.(citation ). Sickle cell anemia is most common in people whose families come from Africa, South or Central America (especially Panama), Caribbean islands, Mediterranean countries (such as Turkey, Greece, and Italy), India, and Saudi Arabia. In the United States, it's estimated that sickle cell anemia affects 70,000–100,000 people, mainly African Americans. The disease occurs in about 1 out of every 500 African American births. Sickle cell anemia also affects Hispanic Americans. The disease occurs in more than 1 out of every 36,000 Hispanic American births (Citation).More than 2 million Americans have sickle cell trait. The condition occurs in about 1 in 12 African Americans. In people with sickle cell disease, approximately 50% do not survive beyond age 20 years, and most people do not live past 50 years of age (Citation)…

    Sickle Cell Anemia

    Sickle cell disease is an autosomal recessive genetic disorder most common in African Americans, which results from a mutation affecting the amino acid sequence of the beta chains of hemoglobin molecules in red blood cells. The abnormal hemoglobin which causes the red blood cells to sickle is called hemoglobin S. Sickling occurs when the red blood cells are deoxygenated causing the cell to have a hard curved crescent shape. Due to their shape the sickle cells can become trapped in blood vessel walls causing a circulatory blockage and could cause tissues to become oxygen deprived, pain, infection, and organ damage. Red blood cells in sickle cell disease also have a life span of 10 to 20 days compared to normal red blood cells of 120 days; because of this shortened life span chronic hemolytic anemia occurs (Thompson, 2012). All together sickle cells disease causes a dramatic decrease in the quality of life that can lead to early death, the absolute need for medical intervention, and transplantations.…

    Sickle cell is inherited and is normally only found in Black Americans. The blood cells are shaped differently and it due to a genetic defect. (WebMD, 2014) This causes the blood cells to eliminate themselves rather quickly causing lack of oxygen to the organs in the body. The reason this disease is so painful is because the blood cells become trapped in the blood vessels. (WebMD, 2014)…

    Sickle Cell Anemia

    Sickle cell anemia or also known as sickle cell disease is a hereditary genetic disease defined by the presence of odd shaped crescent-shaped red blood cells instead of the regular round disc like shape cells. Red blood cells transport oxygen from the lungs to various other organs and tissues with the help of a protein called hemoglobin. The main cause of sickle cell disease is when hemoglobin mutates into an abnormal type called hemoglobin S. The presence of Hemoglobin S causes red blood cells to be sickle-shaped and rigid, making it more difficult for them to flow through blood vessels in the body to deliver oxygen. Therefore, the sickled cells latch onto the walls of various blood vessels throughout the body, resulting in blocked blood flow that can lead to organ damage, pain and infections…

    Sickle Cell Anemia is a the most common single gene disorder found mostly among Black Americans (Wethers, 2000). According to scientific research, it affects approximately one in 375 persons of African ancestry. According to one researcher, "Sickle Cell conditions are also found to be in persons from Mediterranean countries also, such as Turkey, the Arabian peninsula, and the Indian subcontinent"( Wethers, 2000, p.1014). Extensive research has also proved that Spanish speaking persons in the United States, plus people from the Caribbean and South and Central America, are also effected by Sickle Cell Anemia (Wethers, 2000)…

    There are ways to prevent episodic sickle cell crisis such as staying adequately hydrated, limiting physical activities, blood transfusions and taking medication such as hydroxyurea. In Addition, one of the biggest issue with Sickle cell anemia is lack of funding which is due to the fact that it is not officially recognized as a health disparity topic by CDC. Another disparity is the fact that in terms of funding and treatment; SCD pales in comparison to other diseases. the funding disparities for research on sickle cell drugs and cures compared to other pediatric diseases such as Cystic fibrosis. “Cystic fibrosis a disease that affects primarily Caucasians and affects only a third of the numbers of people compared to Sickle cell but still…
