| heat-shock response element | <cell biology, protein> The nucleotide sequence, CNNGAANNTCCNG, which is in the promoter region of the heat-shock genes. When the animal is exposed to certain types of stress such as a sudden rise in temperature, the first thing that happens to activate these genes is the binding of the HSE by a transcriptional enhancer protein. (09 Oct 1997) |

| heat-stable | Thermostable Not readily subject to alteration or destruction by heat. Synonym: heat-stable. Origin: thermo-+ L. Stabilis, stable (05 Mar 2000) |
| heat-stable enzyme | <enzyme> An enzyme that is not readily subject to destruction or alteration by heat. Synonym: heat-stable enzyme. (05 Mar 2000) |
| heat stress disorder | A group of conditions due to overexposure to or overexertion in excess environmental temperature. It includes heat cramps, which are non-emergent and treated by salt replacement; heat exhaustion, which is more serious, treated with fluid and salt replacement; and heatstroke, a condition most commonly affecting extremes of age, especially the elderly, accompanied by convulsions, delusions, or coma and treated with cooling the body and replacement of fluids and salts. (12 Dec 1998) |
| heat transfer efficiency | Useful heat output released to the room divided by the actual heat produced in the firebox (17 Dec 1998) |
| heat treatment | In dentistry, a method of controlled temperature handling of metals so as to change the microscopic structure and thus the physical properties. See: temper, anneal. (05 Mar 2000) |
| heat urticaria | A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
| process heat | Heat used in an industrial process rather than for space heating or other housekeeping purposes. (05 Dec 1998) |
| sensible heat | The amount of heat that, when absorbed by a substance, causes a rise in temperature. Compare: latent heat. (05 Mar 2000) |
| specific heat | The amount of energy (measured in calories or joules) needed to raise thetemperature of one gram of a pure substance by one degree C. (09 Oct 1997) |
| specific heat capacity | <chemistry> The amount of energy required to raise the temperature of one gram of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
| drosophila heat-shock protein | <protein> Proteins which are immediately produced when the Drosophila fruit fly is exposed for a short time to extreme heat or other stress, such as toxic substances or alcohol. (09 Oct 1997) |
| initial heat | The first burst of heat produced after the beginning of a muscle twitch, described by A. V. Hill. (05 Mar 2000) |
| innate heat | In ancient Greek medicine, the heat of the heart sustained by the pneuma and distributed by the arteries throughout the body. (05 Mar 2000) |
| latent heat | The amount of heat that a substance may absorb without an increase in temperature, as in conversion from solid to liquid state (ice to water at 0캜), or from liquid to gaseous state (water to steam at 100캜). Compare: sensible heat. (05 Mar 2000) |
