Is polycythemia a type of anemia?

This may also be referred to as the “spent phase” of polycythemia vera. When this occurs, the marrow can no longer produce blood cells resulting in low levels of healthy, functioning red blood cells (anemia), platelets (thrombocytopenia) and white blood cells (leukopenia).

What is polycythemia caused by?

It’s usually caused by a change in the JAK2 gene, which causes the bone marrow cells to produce too many red blood cells. The affected bone marrow cells can also develop into other cells found in the blood, which means that people with PV may also have abnormally high numbers of both platelets and white bloods cells.

Is polycythemia a cancer?

Polycythemia vera (pol-e-sy-THEE-me-uh VEER-uh) is a type of blood cancer. It causes your bone marrow to make too many red blood cells. These excess cells thicken your blood, slowing its flow, which may cause serious problems, such as blood clots.

What are symptoms of polycythemia?

What are the symptoms of polycythemia vera?

• Headache.
• Dizziness.
• Shortness of breath and trouble breathing while lying down.
• Vision problems, such as double vision, blurred vision, and blind spots.
• Inability to concentrate.
• Night sweats.
• Face and becomes red and warm (flushed)

Where can I download a table of polyatomic ions?

How are the polyatomic ions listed in Chem 151?

The tables below list common polyatomic ions that you will be using throughout this General-Chemistry laboratory series (Chem 151-152). These ions are separated by charge on the ion into four (4) different tables and listed alphabetically within each table.

How is the charge of a polyatomic ion increased?

Nomenclature of polyatomic anions. First, when the prefix bi is added to a name, a hydrogen is added to the ion’s formula and its charge is increased by 1, the latter being a consequence of the hydrogen ion’s +1 charge. An alternative to the bi- prefix is to use the word hydrogen in its place: the anion derived from H+ + CO2− 3, HCO− 3,…

Which is the best definition of a polyatomic molecule?

Definition of polyatomic. : containing more than one and especially more than two atoms polyatomic molecules.
