    processes including an increase in production of bilirubin, decreased hepatic uptake, decreased conjugation, impaired excretion, impaired bile flow, or an in increase in enterohepatic circulation. The bulk of bilirubin comes from the breakdown of hemoglobin into unconjugated bilirubin. Unconjugated bilirubin binds to albumin in the blood so it can be transported to the liver where it is then taken by the hepatocytes and then conjugated with glucuronic acid by an enzyme so it can become water…

    severe anemia due to the abnormal formation of hemoglobin. Thalassemia is inherited by either one or both parents. A mutation in either chromosome 11 (Deisserot et al, 1978) effect the synthesis of beta hemoglobin, whereas a mutation on chromosome 16 affect the synthesis of alpha hemoglobin(Deisserot et al, 1977). Hemoglobin is a tetramer made of two alpha chains and two beta chains (Cao et al, 2010). The location of the mutation in the hemoglobin chains is what characterizes the severity and…

    The traditional sign is cyanosis, which is defined as a concentration of more than 5 g/100 ml of reduced hemoglobin in capillary blood and depends on arterial oxygenation, skin perfusion, and hemoglobin content. In human body the presence of central cyanosis, a blue coloration of the tongue and mucous membranes is thought to be a more reliable indicator of hypoxemia as these tissues are less likely to…

    HBB that is located in the multigene locus of β-globin locus on chromosome 11, specifically on the short arm position 15.5[18]. Mutation in the HBB gene can lead to the formation of hemoglobin S that results in sickle cell anaemia [2]. When oxygen levels are low in the blood, a mutated form of hemoglobin (hemoglobin S aka HbS) alters the red blood cell giving it a crescent-looking shape (see figure 1.11).The abnormal crescent shape mean that red blood cell carry less oxygen, causing illnesses…

    through the blood stream (“Blood doping”). By increasing your red blood cell count, you increase the amount of oxygen your body is capable of moving to your muscles. A single red blood cell contains about 250 million molecules of hemoglobin and each molecule of hemoglobin binds four oxygen molecules to transport to muscles (Bowers). Naturally, increasing the number of red blood cells increases the total amount of oxygen delivered to cells. When…

    Unfortunately, “Fetal hemoglobin normally drops dramatically after birth” [8] [9]. A newborn baby tends to have around 50-80% fetal hameolgobin. A 6 month old baby tends to have around 8% of HbF and over 6-months 1-2%[23]. The importance of fetal haemoglobin (HbF) in sufferers is due to its high oxygen affinity, which means it does not participate in the polymerization process (were abnormal hemoglobin become jammed in blood vessels, hindering the flow of blood…

    blood transfusion, and pain relieving medications. Many people take the drug called Hydroxyurea (Droxia, Hydrea). This medication is to be taken orally and daily to reduce the number of blood transfusions. The medication works by targeting the fetal hemoglobin to reduce the formation of sickle cells. Although Hydroxyurea is taken by millions of sickle cell patients daily. It (Hydroxyurea) can cause a severe decrease in the number of blood cells in your bone marrow. It may also lead to serious…

    iron efflux mechanism. The expression of ferroportin is increased in iron deficiency and hypoxia. (Babitt, 2010; Grotto, 2010). Hepcidin binds to ferroportin, causing its internalization and degradation and in turn affecting the release of iron for hemoglobin synthesis. In patients with CKD, there is an accumulation of…

    A person with a iron-deficiency anemia will have sumptoms such as shortness of breath, dizziness, weakness, and pale skin. Iron is part of the hemoglobin that is found in red blood cells and also, myoglobin which is found in muscle cells. Hemoglobin molecules in red blood cells function to trancsport oxygen (O2) from the lungs to cells. Then, some assist in returning some carbon dioxide (CO2) from cells to the lungs. Iron is part of some enzymes…
