  • (18) The plasmid pMucAMucB, constructed from the Haemophilus influenzae vector pDM2, and a similar plasmid, constructed from pBR322, increased the survival after UV irradiation of Escherichia coli AB1157 with the umu-36 mutation and also caused UV-induced mutation in the E. coli strain.
  • (19) In Stage I, seven relapses (relapse rate 6%) occurred after irradiation; three of them were cured with second-line therapies.
  • (20) By using these methods, it was clearly indicated that these factors such as TDF of rectum, Z-coordinate of weighted geometric center (WGC-Z), the dose of whole pelvic irradiation, history of chemotherapy and Treponema pallidum hemoagglutination test (TPHA) were important for occurrence of rectal complication.

Radiant


Definition:

  • (a.) Emitting or proceeding as from a center; resembling rays; radiating; radiate.
  • (a.) Especially, emitting or darting rays of light or heat; issuing in beams or rays; beaming with brightness; emitting a vivid light or splendor; as, the radiant sun.
  • (a.) Beaming with vivacity and happiness; as, a radiant face.
  • (a.) Giving off rays; -- said of a bearing; as, the sun radiant; a crown radiant.
  • (a.) Having a raylike appearance, as the large marginal flowers of certain umbelliferous plants; -- said also of the cluster which has such marginal flowers.
  • (n.) The luminous point or object from which light emanates; also, a body radiating light brightly.
  • (n.) A straight line proceeding from a given point, or fixed pole, about which it is conceived to revolve.
  • (n.) The point in the heavens at which the apparent paths of shooting stars meet, when traced backward, or whence they appear to radiate.

Example Sentences:

  • (1) The thermoregulatory effects of isothermogenic doses of isoproterenol (Iso) and a novel beta-agonist (BRL 35135) were tested in rats at 22 degrees C and in rats trained to bar press for radiant heat at -8 degrees C. BRL 35135 produced hyperthermia at 22 degrees C and reduced operant responding for heat at -8 degrees C, whereas Iso reduced body temperature and increased operant responding.
  • (2) During five of the treatments skin cooling, by means of initiating air flow through the radiant heating device, was necessary during the plateau phase because rectal temperature exceeded the target value.
  • (3) It has been found that the UV radiation-induced extreme state of the cells in a radiant culture produces distantly in an intact detector culture, which has only an optic contact with it, the cytopathic effect (CPE) as a repercussion of a specificity of morphological manifestations imprinted in the affected culture.
  • (4) Extracellular activity of single WDR neurons in the spinal dorsal horn, which was evoked by a radiant heat stimulus (51 degrees C), was recorded in decerebrate, spinally transected cats.
  • (5) In both patients, there was a more or less remote history of eye exposure to some form of radiant energy, together with other possible etiologic factors.
  • (6) A study was performed to investigate whether measurements of the evaporation rate from the skin of newborn infants by the gradient method are affected by the presence of non-ionizing radiation from phototherapy equipment or a radiant heater.
  • (7) Tiny (0.2% TBS), partial thickness, non-contact radiant heat burns in guinea pigs resulted, within 3 hours, in significant edema formation and protein leakage at the site of the injury.

  • (10) The water losses create an additional problem in managing infants under radiant warmers.
  • (11) After Second World War army service, his physique, graceful carriage and radiant grin took him from lift attendant to Broadway and instant movie stardom in The Killers (1946).

  • (13) The Bair Hugger set on "medium" decreased heat loss more than each radiant warming device and as much as the circulating-water blanket.
  • (14) Tail-flick latency (the time needed to evoke the tail-flick reflex by noxious radiant heat) was reduced for 1-4 min after intrathecal administration of substance P (5 micrograms), but the tail skin temperature was not significantly changed.
  • (15) She looks cheery when attacking, even cheerier when attacked and absolutely radiant when descending into a bog of half-truths and fictions.
  • (16) Compensation for cold air temperature was imperfect because the chicks avoided zones of high radiant flux.
  • (17) Above threshold, mass removal rates were proportional to laser radiant exposure.
  • (18) A model of ocular and facial skin exposure to UVB is presented that combines interview histories of work activities, leisure activities, eyeglass wearing, and hat use with field and laboratory measurements of UV radiant exposure.
