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)

1. Pertaining to or causing the production of low temperatures.
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.

cryogenic (adjective), more cryogenic, most cryogenic
A reference to freezing: A girl started to research cryonic preservation online, and although it is a controversial and costly process that involves the freezing of a dead body in the hope that resuscitation and a cure may one day be possible, she decided she wanted to be frozen after her death.
cryogenically (adverb), more cryogenically, most cryogenically
Pertaining to freezing something at zero temperatures: A 14-year old girl, who died of cancer, told a judge before her death that she wanted to be cryogenically frozen so she could be brought back to life "in hundreds of years".
cryogenics (pl) (noun) (a plural form used as a singular)
1. The branch of science that deals with the realm of extremely low temperatures and their effects on matter.
2. The science concerned with the production and effects of very low temperatures, particularly temperatures in the range of liquid helium.

A serum globulin (invariably an immunoglobulin) that precipitates at low temperatures.

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.

The presence of abnormal quantities of cryoglobulin in the blood plasma that causes gelling at low temperatures.

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.

cryohemia, cryohemic
1. Cold-blooded.
2. A condition of having cold blood.
1. A mixture of ice and a salt combined in a proportion designed to have the lowest possible melting point.
2. A eutectic mixture, especially one having water as one of its constituents.
Destruction of hypophysis by the application of extreme cold.

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.

A therapeutic process that includes the application of externally cold therapy to an area and which is followed with a full passive range of movements.
1. The cooling of an area in order to injure or to destroy it. This is done for therapeutic reasons.
2. A lesion (injury, wound, or infected patch in a skin disease) produced by exposure to cold; such as, frosbite.
With reference to its icy appearance, a fluoride of sodium and aluminum found in Greenland and used in the molten state in the electrolytic production of aluminum.
In hydrology, the study of the nature, structure, and development of underground ice, especially in permafrost regions.
1. In hydrology, the scientific study of snow and ice.
2. In mechanical engineering, studying and researching refrigeration at low temperatures ranging down to absolute zero.
A “frozen-crested lizard” from Early Jurassic.

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.
