  1. Myeloproliferative disorders Myeloproliferative disorders
    Myeloproliferative disorders: Malignant diseases of certain bone marrow cells including those that give rise to the red blood cells, the granulocytes (types of white blood cells), and the platelets (crucial to blood clotting). The myeloproliferative disorders include myelophthisic anemia, eryth...
  2. MYH MYH
    MYH: A base excision repair gene responsible for an hereditary colon cancer syndrome. MYH is located on the short (p) arm of chromosome 1 in region 1p34.3-p32.1. MYH encodes an enzyme that removes the base adenine from mispairs (with 8-oxoguanine) that arise during the replication of oxidized DNA. M...
  3. MYH syndrome MYH syndrome
    MYH syndrome: See: MYH....
  4. Myo- (prefix) Myo- (prefix)
    Myo- (prefix): A prefix denoting a relationship to muscle. Myo- enters into many words and terms in medicine including cardiomyopathy, dermatomyositis, electromyography, leiomyoma, myocardial infarction, myocarditis, myocardium, myoclonic, myocyte, myopathy, myoglobin, myometrium, myotonia, myotoni...
  5. Myocardial bridge Myocardial bridge
    Myocardial bridge: Literally a bridging of heart muscle over one of the major arteries to the heart (usually the left anterior descending artery). The heart has formed in this abnormal design from birth, whereby the artery is actually 'tunneled' through a part of the heart muscle....
  6. Myocardial infarction Myocardial infarction
    Myocardial infarction: A heart attack. Abbreviated MI. The term "myocardial infarction" focuses on the myocardium (the heart muscle) and the changes that occur in it due to the sudden deprivation of circulating blood. The main change is necrosis (death) of myocardial tissue. The word "infarction" ...
  7. Myocardial infarction, acute Myocardial infarction, acute
    Myocardial infarction, acute: See: Acute myocardial infarction....
  8. Myocarditis Myocarditis
    Myocarditis: Inflammation of the myocardium, the heart muscle. Myocarditis can be caused by a number of different conditions. The most common cause is infection of the heart muscle by a virus. The virus causes the initial heart muscle inflammation. After the initial viral infection subsides, the bod...
  9. Myocarditis, viral Myocarditis, viral
    Myocarditis, viral: Inflammation of the muscles in the walls of the heart due to a viral infection. Among the offenders are dozen of different common viruses, including the adenovirus, coxsackievirus, poliovirus, echoviruses, and influenza viruses.

  12. Myoclonic twitch Myoclonic twitch
    Myoclonic twitch: A rapid, involuntary muscle contraction, particularly near the eye. Myoclonic tics resemble, and may be mistaken for, tics. Like tics, they tend to occur more often when the person is under stress; unlike tics, they are not preceded by any sensation and they cannot be delayed....
  13. Myoclonus Myoclonus
    Myoclonus: A condition of abnormal contraction of muscles or portions of muscles. ...
  14. Myocyte Myocyte
    Myocyte: A muscle cell. From myo-, muscle + -cyte, cell = muscle cell. "Remaining young at heart is a desirable but elusive goal. Unbeknown to us, however, myocyte regeneration may accomplish just that." (Nature 415, 240, 2003)...
  15. Myocyte, cardiac Myocyte, cardiac
    Myocyte, cardiac: See: Cardiac myocyte....
