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.
Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
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 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.

Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [1]
Afterload is the mean tension produced by a chamber of the heart in order to contract. It can also be considered as the ‘load’ that the heart must eject blood against. Afterload is, therefore, a consequence of aortic large vessel compliance, wave reflection, and small vessel resistance (LV afterload) or similar pulmonary artery parameters (RV afterload
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.
