| whole-body irradiation | Irradiation of the whole body with ionizing or non-ionizing radiation. It is applicable to humans or animals but not to microorganisms. (12 Dec 1998) |
| cranial irradiation | The exposure of the head to roentgen rays or other forms of radioactivity for therapeutic or preventive purposes. (12 Dec 1998) |
| hemibody irradiation | Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (uhbi) or lower hemibody irradiation (lhbi). Less common is mid-body irradiation (mbi). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with whole-body irradiation. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (p. Rubin et al. Cancer, vol 55, p2210, 1985) (12 Dec 1998) |
| prophylactic cranial irradiation | Radiation therapy to the head to prevent cancer from spreading to the brain. (12 Dec 1998) |
| irradiation | Treatment by ionising radiation, such as X-rays or radioactive sources such as radioactive iodine seeds. See: radiation therapy. (16 Dec 1997) |
| total body irradiation | Radiotherapy often given in several doses prior to bone marrow transplantation with the aim of killing any residual leukaemia in the patient. It is used in conjunction with high-dose anti-cancer drugs. The procedure and its side-effects will be discussed individually with the patient. (13 Nov 1997) |
| lymphatic irradiation | External or interstitial irradiation to treat lymphomas (e.g., hodgkin's and non-hodgkin's lymphomas) and lymph node metastases and also some autoimmune diseases, such as rheumatoid arthritis. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte, heavy chain | Ordered rearrangement of b-lymphocyte variable gene regions thereby contributing to antibody diversity. It occurs during the first stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| metals, heavy | metals with high specific gravity, typically larger than 5. They have complex spectra, form coloured salts and double salts, have a low electrode potential, are mainly amphoteric, yield weak bases and weak acids, and are oxidizing or reducing agents (12 Dec 1998) |
| MyoD heavy chain kinase | <enzyme> Required for actin activation of the magnesium atpase activity of dictyostelium myosin id (myod); specific for myod Registry number: EC 2.7.1.- Synonym: 110-kD protein kinase, dictyostelium, dictyostelium 110-kD protein (26 Jun 1999) |
| myosin heavy chain | <protein> See myosin: do not confuse with heavy meromyosin which is a subfragment of the heavy chain of myosin II. (18 Nov 1997) |
| myosin heavy chains | The heavy chains of the muscle protein myosin. Each molecule of myosin is composed of two heavy chains and two pairs of light chains. The heavy chains have a molecular weight of about 230 kD and each heavy chain is associated with a dissimilar pair of light chains. (devlin, textbook of biochemistry: with clinical correlations, 3rd ed, p957) (12 Dec 1998) |
| heavy | 1. Heaved or lifted with labour; not light; weighty; ponderous; as, a heavy stone; hence, sometimes, large in extent, quantity, or effects; as, a heavy fall of rain or snow; a heavy failure; heavy business transactions, etc.; often implying strength; as, a heavy barrier; also, difficult to move; as, a heavy draught. 2. Not easy to bear; burdensome; oppressive; hard to endure or accomplish; hence, grievous, afflictive; as, heavy yokes, expenses, undertakings, trials, news, etc. "The hand of the Lord was heavy upon them of Ashdod." (1 Sam. V. 6) "The king himself hath a heavy reckoning to make." (Shak) "Sent hither to impart the heavy news." (Wordsworth) "Trust him not in matter of heavy consequence." (Shak) 3. Laden with that which is weighty; encumbered; burdened; bowed down, either with an actual burden, or with care, grief, pain, disappointment. "The heavy [sorrowing] nobles all in council were." (Chapman) "A light wife doth make a heavy husband." (Shak) 4. Slow; sluggish; inactive; or lifeless, dull, inanimate, stupid; as, a heavy gait, looks, manners, style, and the like; a heavy writer or book. "Whilst the heavy plowman snores." (Shak) "Of a heavy, dull, degenerate mind." (Dryden) "Neither [is] his ear heavy, that it can not hear." (Is. Lix. 1) 5. Strong; violent; forcible; as, a heavy sea, storm, cannonade, and the like. 6. Loud; deep; said of sound; as, heavy thunder. "But, hark! that heavy sound breaks in once more." (Byron) 7. Dark with clouds, or ready to rain; gloomy; said of the sky. 8. Impeding motion; cloggy; clayey; said of earth; as, a heavy road, soil, and the like. 9. Not raised or made light; as, heavy bread. 10. Not agreeable to, or suitable for, the stomach; not easily digested; said of food. 11. Having much body or strength; said of wines, or other liquors. 12. With child; pregnant. Heavy artillery. <chemistry> See Metal. Heavy weight, in wrestling, boxing, etc, a term applied to the heaviest of the classes into which contestants are divided. Cf. Feather weight, under Feather. Heavy is used in composition to form many words which need no special explanation; as, heavy-built, heavy-browed, heavy-gaited, etc. Origin: OE. Hevi, AS. Hefig, fr. Hebban to lift, heave; akin to OHG. Hebig, hevig, Icel. Hofigr, hofugr. See Heave. Source: Websters Dictionary (01 Mar 1998) |
| heavy chain | <protein> In general, the larger polypeptide in a multimeric protein. Thus the immunoglobulin heavy chain is of 50 kD, the light chain of 22 kD, whereas in myosin the heavy chain is very much larger (220 kD) than the light chains (~20 kD). (18 Nov 1997) |
