Abstract:
Moyamoya disease is a rare cerebrovascular condition characterized by steno-occlusive disease of the major intracranial arteries at the base of the brain, and the appearance of innumerable, tiny, arterial collaterals that resemble a "puff of smoke." Although it has been associated with hematologic diseases such as sickle-cell disease, the association with other hemoglobinopathies is less frequently observed. We describe the association of a unique hemoglobinopathy (hemoglobin Fairfax) with beta-thalassemia and moyamoya disease in a 9-year-old girl with a history of stroke. To our knowledge, this is the first report of this unstable hemoglobin with moyamoya disease, and it emphasizes the potential for cerebral infarction due to the severe anemia of hemolytic disease.

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
