cryo-, cry-, kryo-, kry-
(Greek: cold, very cold, freezing; used to describe the effects of low temperatures or activities carried on at a very low temperature)
2. Relating to cryogenics.
3. Cryogenic lake, a lake formed by local thawing in an area of permanently frozen ground.
4. Relating to the deep-refrigeration domain involving temperatures below 120 Kelvin.
Describing a substance; such as hydrogen, stored at such a low temperature.
2. The science concerned with the production and effects of very low temperatures, particularly temperatures in the range of liquid helium.
An abnormal blood protein that has the unusual properties of precipitating from the blood serum when it is chilled (hence the "cryo-") and redissolving when it is rewarmed. Cryoglobulins are gamma globulins with a molecular weight of approximately 200,000.
Cryoglobulins can cause problems by causing the blood to be abnormally "thick" which increases the risk of blood clots forming in the brain (stroke), eyes, and heart.
Cryoglobulins are also associated with inflammation of blood vessels (vasculitis) which increases the risk of blockage of arteries.
Cryoglobulins are a key part of a condition called essential mixed cryoglobulinemia. Cryoglobulins can also accompany diseases such as multiple myeloma, dermatomyositis, and lymphoma.
Sometimes small amounts of cryoglobulin are discovered by accident in the laboratory in a serum sample from someone with no apparent symptoms.
Cryoglobulins are abnormal proteins that by definition have the unusual property of precipitating from the serum specimen in the laboratory when it is chilled and redissolving into the serum upon rewarming.
Cryoglobulins may or may not be causing disease. Cryoglobulins can accompany another condition (such as dermatomyositis, multiple myeloma, or lymphoma) or be an isolated condition themselves, called cryoglobulinemia.
2. A condition of having cold blood.
2. A eutectic mixture, especially one having water as one of its constituents.
The hypophysis is a pituitary gland which is a small oval shaped endocrine gland situated at the base of the brain in the fossa (depression) of the sphenoid bone.
The overall role of the hypophysis (pituitary gland) is to regulate growth and metabolism. The gland is divided into the posterior and anterior pituitary, each responsible for the production of its own unique hormones.
2. A lesion (injury, wound, or infected patch in a skin disease) produced by exposure to cold; such as, frosbite.
2. In mechanical engineering, studying and researching refrigeration at low temperatures ranging down to absolute zero.
The name is a reference to both the freezing conditions under which the fossil remains of a large theropod were extracted on Mount Kirkpatrick in the Queen Alexandra Range, west central Antarctica, and to the unusual ridged, transverse bony crest on the animal’s forehead.
It was originally compared to Elvis Presley’s 1950’s pompadour hair-do. Named by U. S. paleontologists William R. Hammer and Hickerson in 1994.
