  • (17) It hasn't been reported that the neurons in somatosensory area I (SI) may respond to the noxious stimulation.
  • (18) Stimuli used to activate the cells orthodromically were graded innocuous and noxious mechanical stimuli, including sinusoidal vibration and thermal pulses.
  • (19) This cannot be explained by metabolic activation of the halogenated hydrocarbons but could be due to a noxious effect on the mitotoc spindle.
  • (20) Suppression of the tail flick response to noxious heat and paw withdrawal response to noxious pressure were produced by electrical stimulation of arcuate nucleus of the hypothalamus (ARH) in pentobarbital anesthetized rats.

Virulent


Definition:

  • (a.) Extremely poisonous or venomous; very active in doing injury.
  • (a.) Very bitter in enmity; actuated by a desire to injure; malignant; as, a virulent invective.

Example Sentences:

  • (1) The combined analysis of pathogenesis and genetics associated with the salmonella virulence plasmids may identify new systems of bacterial virulence and the genetic basis for this virulence.
  • (2) Escherichia enterotoxigenic strains, Yersinia enterocolitica and Salmonella typhimurium virulent strains, Campylobacter jejuni clinical isolates possess more pronounced capacity for adhesion to enteric cells of Peyer's plaques than to other types of epithelial cells, which may be of importance in the pathogenesis of these infections.
  • (3) The results are consistent with our previous suggestion that lethality for virulent SFV infection results from a lethal threshold of damage to neurons in the CNS and that attenuating mutations may reduce neuronal damage below this threshold level.
  • (4) The results point out the importance of detecting specific virulence factors before incriminating water as a source of human diarrhea.
  • (5) We put forward the hypothesis that the agglutinability in acriflavine, together with the PAGE profile type II, may be associated with particular structures responsible for virulence.
  • (6) One mutant, BS260, was completely noninvasive on HeLa cells and mapped to a region on the 220-kb virulence plasmid in which we had previously localized several avirulent temperature-regulated operon fusions (A.E.
  • (7) The proteins of two HEV isolates, one apathogenic (HEV-A) and one virulent (HEV-V), resembled each other in most respects.
  • (8) The geometric mean titers of anti-Shigella antibodies to virulence plasmid-associated antigens in milk received before infection were eightfold higher in infants who remained well than in those in whom diarrhea developed.

  • (10) Some of these strains have been used by investigators to study gonococcal virulence.
  • (11) With the faster rate of proliferation there was a corresponding increase in virulence.
  • (12) On average, clinical isolates were not more virulent than fecal isolates.
  • (13) Since the four determining coefficients may change over evolutionary time-scales, the mathematical results together with a natural selection argument proves that virulence gamma 2 attenuates.
  • (14) It also devalues the courage of real whistleblowers who have used proper channels to hold our government accountable.” McCain added: “It is a sad, yet perhaps fitting commentary on President Obama’s failed national security policies that he would commute the sentence of an individual that endangered the lives of American troops, diplomats, and intelligence sources by leaking hundreds of thousands of sensitive government documents to WikiLeaks, a virulently anti-American organisation that was a tool of Russia’s recent interference in our elections.” WikiLeaks last year published emails hacked from the accounts of the Democratic National Committee and John Podesta, chairman of Hillary Clinton’s election campaign.
  • (15) Understanding the molecular biology of a virulence factor also provides information about potential targets for future therapies and preventive modalities.
