Sickle Cell Anemia ( Sca )

Approximately 100,000 people suffer from Sickle Cell Anemia everyday and about 2 million people have the Sickle Cell trait in the United States alone. Sickle cell disease is the most common inherited blood disorder in the United States, affecting 70,000 to 80,000 Americans (Pruthi 2018). The disease is estimated to occur in 1 in 500 African Americans and 1 in 1,000 to 1,400 Hispanic Americans (Pruthi 2018). Sickle cell anemia is an inherited form of anemia, a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become

This paper will discuss Sickle Cell Anemia. It will describe what the disease is as well as how its contracted. The paper will go on to on to discuss the symtoms risk and statistics of sickle cell aniema. The paper will end with discussing treatment for the disease.

Sickle cell anaemia is a disorder affecting the red blood cells and up to 100,000 people are estimated to have the disease in the USA (Centre for Disease Control). Due to a genetic mutation in the gene responsible for the production of haemoglobin (MayoClinic, 2014) the red blood cells, which are usually a biconcave disk in shape, become sickle (bent) shaped (Figure 1) and the haemoglobin that the red blood cells contain is defective. Haemoglobin is a protein that carries oxygen (which has bind to the haemoglobin) around the body from the lungs after gas exchange. Having defective haemoglobin, as is the case with sickle cell anaemia, means

Sickle cell anemia (SCA) is an inherited disease of the blood that is characterized by the production of abnormal hemoglobin S causing the cell to acquire a sickle shape that prevents the smooth flow of blood to a major organ (Shea et al. 2017). The stress is usually caused by fever, infection or cold temperature, which lead to sickle cell crisis caused by hypoxia, dehydration, and acidosis (Barranger, 2017).

Sickle cell disease (SCD) is an inherited and noncontagious, lifelong condition. More specifically, per Ohaeri, Shokunbi, Akinlade, & Dare, 1995, SCD is a generic term for a group of genetic disorders characterized by the predominance of sickle cell hemoglobin (Hgb). Hemoglobin is a protein in the red blood cells that carries oxygen throughout the body. The disease produces significantly abnormal Hgb molecules in red blood cells (RBCs). In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body (Ohaeri, Shokunbi, Akinlade, & Dare, 1995, p. 955.Individuals

Sickle-cell Anemia is a disorder that is typically inherited from a person's parents. Sickle-cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin (haemoglobin S) that is found in red blood cells. In such a condition the red blood cells contort into a sickle shape. The affected cells die early which results to a shortage of healthy red blood cells and can block blood flow causing pain. The disease s caused by gene mutation through the process of substitution. In the Sickle-cell condition one Amino Acid; glutamic acid is always replaced by another acid valine. This happens in each of the two polypeptide chains of the haemoglobin molecule.This alteration results to a haemoglobin type S that is defective and is genetically

Sickle cell anemia, a genetic disease that affects a minority of individuals with African, Indian, and Mediterranean heritage, has been present in Africa for thousands of years, but was only recently “discovered” by countries outside of Africa. The so-called discovery occurred in 1904 when a young African-American dental student complained to Dr. James B. Herrick of chronic pain episodes. Because Dr. Herrick’s speciality was cardiology, he deferred the case to another doctor, Dr. Ernest Iron, to the case. While examining the student’s blood under a microscope, Dr. Earnest Iron discovered an interesting anomaly; he aptly described the red blood cells as “having the shape of a sickle”. After being referred

What is sickle cell anemia? Sickle cell anemia is a severe hereditary form of anemia in which a mutated forms of hemoglobin (a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule

. The 3-D tertiary structure of polypeptide proteins globular and is the result of interactions that occur between R groups. Tertiary structure is a result of the bonds between sidechains of amino acids, the R groups. The structure and bonds involve alpha helices, beta pleated sheets, and also regions unique to each protein. Tertiary proteins are held together by four different types of forces; hydrogen bonds, hydrophobic interactions (including Van der Waals interactions), ionic bonding (electrostatic interactions), and disulfide bridges (strong covalent bonds). Hydrogen bonds occur within and between polypeptide chains and the aqueous environment. Hydrogen bonding forms between a highly electronegative oxygen atom or a nitrogen atom and a hydrogen atom attached to another oxygen atom or a nitrogen atom. This links the amino acid

Sickle Cell disease (SCD) is an inherited blood disorder in which abnormal hemoglobin is produced in red blood cells. The body creates sickle red blood cells, which are crescent shaped instead of the typical round shape. This shape of the sickle cells are stiff, as well as stick and because of this they tend to block blood flow in the blood vessels of the limbs and organs. This blockage will cause pain and organ damage, as well as serious infection. (National Heart, Lung, and Blood Institute [NHLBI], 2014.). Sickle Cell Disease is also known as sickle cell anemia and Hemoglobin SS Disease.

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.

As an answer, hemoglobin molecules don 't display suitably, causing red blood cells to be stiff and take on a concave shape (like a sickle used to trim wheat). These adequate shaped cells get hooked in the blood vessels and are unable to transport oxygen effectively, causing pain and damage to the organs.

Antibodies are made up of two identical heavy (H) chains and two identical light (L) chains as shown in Figure 1 below. Both the heavy and light chains consist of variable domains and constant domains. The variable domains (VH & VL shown in red in Figure 1) which are at the tip of ‘Y’ shaped molecules are responsible for the specificity as it is unique to a particular type of antigen. This is known as the antigen binding site (Fab). To ensure specificity, grooves present on top of Fab region must have a complementary shape with the epitope of the antigen. Constant region of the antibody
