Normal red blood cells
are flexible and disc-shaped but in sickle cell they can become rigid and shaped like a crescent - or sickle.
The essential component of red blood cells
is a red pigment called haemoglobin, which grabs oxygen in the lungs and carries it around the body.
The grade is determined for hyposegmentation, by the percentage of neutrophils with bilobed and unilobed nuclei; for hypogranularity, by the number of hypogranular cells as a percentage of all granulocytes; for cytoplasmic fragments and hypogranular platelets, as a percentage of the sum of all platelets and cytoplasmic fragments; and for smudge cells, based on smudge cells as a percentage of all white blood cells
When infection occurs, white blood cells
rush through the bloodstream to fight oft the germs.
Older adults who develop chronic leukemia sometimes produce so many abnormal white cells that other blood cells
Sickle cell disease causes red blood cells
, which are normally disc-shape, to become sickle-shape (crescent-shape).
The Working Group plans to address leukocyte reduction of red blood cells
at its next meeting, later this year.
Endurance athletes can also destroy a small number of their red blood cells
during training and competition, which may affect their performance.
The Biopure recipe may be even more efficient than your own red blood cells
at delivering oxygen to body tissues.
In addition, data to be presented from an animal model study demonstrate post-transfusion viability and safety of treated red blood cells
transfused in single and multiple doses.
The INTERCEPT Blood System, which is based on Cerus' proprietary nucleic acid crosslinking technology, is designed to enhance the safety of donated blood components by inactivating viruses, bacteria, and parasites, as well as potentially harmful white blood cells
As simple strands unattached to red blood cells
, they might model other common biological machines, hairlike cilia.
Kendyl has aplastic anemia, a rare blood disease that results when the bone marrow, the spongy interior of the bones, fails to produce red and white blood cells
The system, which is being jointly developed by Cerus and Baxter Healthcare Corporation, is designed to inactivate viruses, bacteria, other pathogens and white blood cells
in platelets intended for transfusion.
There are about 7,000 to 10,000 white blood cells
in a drop of blood.
