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.
Polycythemia vera (PCV) (a.k.a. polycythemia rubra vera (PRV)) occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. [3] Often, excess white blood cells and platelets are also produced. A hallmark of polycythemia vera is an elevated hematocrit, with Hct > 55% seen in 83% of cases. [20]
Keeshonds and Bulldogs are predisposed. Signs include cyanosis and exercise intolerance.

B3. No evidence of polycythemia vera. hematocrit < midpoint of normal range or normal red cell mass in presence of normal iron stores; B4. No evidence of chronic myeloid leukemia. But the Philadelphia chromosome may be present in up to 10% of cases.
Octopuses have 500 million neurons, which is nearly as many neurons as dogs. What’s different about the octopus is that the neurons aren’t all in a central brain, but are spread out throughout ...
