Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. ( Hypo - refers to less, and chromic means colour .) A normal red blood cell has a biconcave disk shape and will have an area of pallor in its center when viewed microscopically. In hypochromic cells, this area of central pallor is ...
Sickle cell disease, in which a mutation in the globin gene causes the formation of sickle hemoglobin. This disease is marked by the manifestation of chronic compensated hemolytic anemia, with laboratory findings not limited to unconjugated hyperbilirubinemia but also elevated serum lactate dehydrogenase and low serum haptoglobin.
Sickle cell-Hb Lepore Boston syndrome is a type of sickle cell disease (HbS) that differs from homozygous sickle cell disease where both parents carry sickle hemoglobin. In this variant one parent has the sickle cell hemoglobin the second parent has Hb Lepore Boston, the only one of the three variants described in association with HbS.
Sickle cell nephropathy is a type of nephropathy associated with sickle cell disease which causes kidney complications as a result of sickling of red blood cells in the small blood vessels. The hypertonic and relatively hypoxic environment of the renal medulla, coupled with the slow blood flow in the vasa recta, favors sickling of red blood ...
The only cure for the pain sickle cell disease can cause is a bone marrow transplant or gene therapies like the one commercially approved by the U.S. Food and Drug Administration in December. A 12 ...
The pathogen that causes the disease spends part of its cycle in the red blood cells and triggers an abnormal drop in oxygen levels in the cell. In carriers, this drop is sufficient to trigger the full sickle-cell reaction, which leads to infected cells being rapidly removed from circulation and strongly limiting the infection's progress.
Human genetic enhancement. Human genetic enhancement or human genetic engineering refers to human enhancement by means of a genetic modification. This could be done in order to cure diseases ( gene therapy ), prevent the possibility of getting a particular disease [1] (similarly to vaccines), to improve athlete performance in sporting events ...
Presentation. The condition is asymptomatic, and is only noticed when screening for other hemoglobin disorders. [citation needed]Sickle cell disease. In persons with sickle cell disease, high levels of fetal hemoglobin as found in a newborn or as found abnormally in persons with hereditary persistence of fetal hemoglobin, the HbF causes the sickle cell disease to be less severe.
