  2. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

    Normal red blood cells are quite elastic and have a biconcave disc shape, which allows the cells to deform to pass through capillaries. In sickle cell disease, low oxygen tension promotes red blood cell sickling and repeated episodes of sickling damage the cell membrane and decrease the cell's elasticity. These cells fail to return to normal ...

  3. Sickle cell trait - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_trait

    An individual with the sickle cell trait shows incomplete dominance when the shape of the red blood cell is considered. This is because the sickling happens only at low oxygen concentrations. With regards to the actual concentration of hemoglobin in the circulating cells, the alleles demonstrate co-dominance as both 'normal' and mutant forms co ...

  4. Transfusion therapy (Sickle-cell disease) - Wikipedia

    en.wikipedia.org/wiki/Transfusion_therapy...

    Transfusion therapy for sickle-cell disease entails the use of red blood cell transfusions in the management of acute cases of sickle cell disease and as a prophylaxis to prevent complications by decreasing the number of red blood cells (RBC) that can sickle by adding normal red blood cells. [citation needed]

  5. Why we need more Black blood donors to treat sickle cell anemia

    CNN staffer Sharon Browne-Peter was diagnosed with sickle cell disease before she was born and needs regular blood transfusions to stay healthy. Ethnically-matched blood offers the best treatment ...

    Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition. [1]

  7. Hemorheology - Wikipedia

    en.wikipedia.org/wiki/Hemorheology

    One such blood analog is an aqueous solution of Xanthan gum and glycerin developed to match both the viscous and elastic components of the complex viscosity of blood. [27] Normal red blood cells are deformable but many conditions, such as sickle cell disease, reduce their elasticity which makes them less deformable. Red blood cells with reduced ...

  8. Hemoglobin C - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_C

    Their red blood cells contain both hemoglobin C and either normal hemoglobin A or hemoglobin S. Hemoglobin C mutation is an autosomal recessive disorder that results from the biparental inheritance of the allele that encodes for hemoglobin C. [6] If both parents are carriers of hemoglobin C, there is a chance of having a child with hemoglobin C ...

  9. Poikilocytosis - Wikipedia

    en.wikipedia.org/wiki/Poikilocytosis

    Poikilocytosis is variation in the shapes of red blood cells. Poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted. Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell. [1]
