The evaluation of new drugs designed to treat specific anemias should include a thorough understanding of underlying pathophysiology, with a focus on enhancing oxygen transport. In this concise review ...

Red-blooded genealogists take note: The discovery in microbes of two oxygen-packing proteins, the earliest known ancestors to hemoglobin, brings scientists closer to identifying the earliest life ...

Three patients heterozygous for hemoglobin Seattle were found to be anemic, with hematocrit levels of 24 to 33 per cent. Urinary erythropoietin excretion was 1 to 4 units per day. This low value ...

Researchers have discovered crucial information about the protein transporter of oxygen, which opens up the possibility to optimize its function by introducing modifications. The transport of oxygen ...

How proteins evolved the ability to form complexes made up of multiple subunits—and what functions this new structure enabled in early multimeric proteins—isn’t well understood. To better understand ...

Hemoglobin helps red blood cells carry oxygen to your muscles and tissues. Abnormal hemoglobin levels can be a sign of several health problems. Hemoglobin is a component of your blood that delivers ...

Hemoglobin is an iron-rich protein in red blood cells that enables the blood to carry oxygen to tissues throughout the body. Low hemoglobin levels often indicate anemia, but high levels can also be a ...

ARLINGTON, Va.– Red-blooded genealogists take note: The discovery in microbes of two oxygen-packing proteins, the earliest known ancestors to hemoglobin, brings scientists closer to identifying the ...
