Vasoocclusion in Sickle Cell Anemia

Probing vasoocclusion phenomena in sickle cell anemia via mesoscopic simulations.

Vasoocclusion crisis is a key hallmark of sickle cell anemia. Although early studies suggest that this crisis is caused by blockage of a single elongated cell, recent experiments have revealed that vasoocclusion is a complex process triggered by adhesive interactions among different cell groups in multiple stages. However, the quantification of the biophysical characteristics of sickle cell ane...

Side Effects of Hydroxyurea in Patients with Sickle Cell Anemia

Background: Hemoglobin S arises is the result of a point mutation (A-T) in the sixth codon on the -globin gene on chromosome 11 causing sickle cell anemia. The presence of fetal hemoglobin in infancy plays a relatively protective role for vaso-occlusive symptoms that are the major contributor for the morbidity and mortality among patients with sickle cell anemia. hydroxyurea, an s-phase-specif...

Sickle cell vasoocclusion and rescue in a microfluidic device.

The pathophysiology of sickle cell disease is complicated by the multiscale processes that link the molecular genotype to the organismal phenotype: hemoglobin polymerization occurring in milliseconds, microscopic cellular sickling in a few seconds or less [Eaton WA, Hofrichter J (1990) Adv Protein Chem 40:63-279], and macroscopic vessel occlusion over a time scale of minutes, the last of which ...
