In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [ 2 ] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.

PV polycythemia vera PVC (VPC) premature ventricular contraction: PVD: peripheral vascular disease: PVFS: post-viral fatigue syndrome: PVI: Peripheral vascular insufficiency Pulmonary vein isolation PVOD: Pulmonary venoocclusive disease: PVR: pulmonary vascular resistance Postvoid residual urine volume PVS: perivascular space persistent ...
This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human hematologic system—the biological system that includes plasma, platelets, leukocytes, and erythrocytes, the major components of blood and the bone marrow.
The area enclosed by the PV loop is a measure of the ventricular stroke work, which is a product of the stroke volume and the mean aortic or pulmonary artery pressure (afterload), depending on whether one is considering the left or the right ventricle.
Parvalbumin (PV) is a calcium-binding protein with low molecular weight (typically 9-11 kDa). In humans, it is encoded by the PVALB gene. It is a member of the albumin family; it is named for its size ( parv- , from Latin parvus which means "small") and its ability to coagulate.
(A separate printable image is available for mass and molarity) Hormones predominate at the left part of the scale, shown with a red at ng/L or pmol/L, being in very low concentration. There appears to be the greatest cluster of substances in the yellow part (μg/L or nmol/L), becoming sparser in the green part (mg/L or μmol/L).
Hypoxic pulmonary vasoconstriction (HPV), also known as the Euler–Liljestrand mechanism, is a physiological phenomenon in which small pulmonary arteries constrict in the presence of alveolar hypoxia (low oxygen levels).
