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.
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.
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.

In respiratory physiology, the ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the ventilation-perfusion coupling and thus the matching of two variables:
The pathophysiology of pulmonary valve stenosis consists of the valve leaflets becoming too thick (therefore not separate one from another), which can cause high pulmonary pressure, and pulmonary hypertension. This however, does not mean the cause is always congenital.
The cancer formulation of the drug, known as PV-10, is currently undergoing clinical trials for melanoma, [2] breast cancer. [ 3 ] and neuroendocrine tumors . The company also has formulated a drug based on rose bengal for the treatment of eczema and psoriasis ; this drug, PV-10, is currently in clinical trials as well.
