  • (19) The presence of cardiovascular hyperreactivity together with the absence of noncardiovascular hyperreactivity in HT indicates heightened SNS-activity specific to the cardiovascular system and not part of generalized SNS-arousal.
  • (20) In this study, therefore, we measured hypercapnic ventilatory responsiveness (HCVR) and spirometry in 13 healthy male subjects (18 to 30 yr of age) after two consecutive nights of severe sleep fragmentation (arousal to an auditory stimulus after each minute of sleep) and compared the results with those obtained in the same subjects after normal sleep.

Stimulation


Definition:

  • (n.) The act of stimulating, or the state of being stimulated.
  • (n.) The irritating action of various agents (stimuli) on muscles, nerves, or a sensory end organ, by which activity is evoked; especially, the nervous impulse produced by various agents on nerves, or a sensory end organ, by which the part connected with the nerve is thrown into a state of activity; irritation.

Example Sentences:

  • (1) Stimulation of human leukocytes with various chemical mediators such as TPA, f-Met-Leu-Phe, LTB4, etc.

  • (3) After stimulation with lipopolysaccharide and calcium ionophore A23187, culture supernatants of clones c18A and c29A showed cytotoxic activity against human melanoma A375 Met-Mix and other cell lines which were resistant to the tumor necrosis factor, lymphotoxin and interleukin 1.
  • (4) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
  • (5) In conclusion, in S-rats a glucose-stimulated insulin release is accompanied by an increase in IBF, but this is not observed in P-rats.
  • (6) Stimulation is also observed with mixtures of APC expressing DPw3 and APC expressing A1, and likewise, DPw3+ APC become stimulatory when preincubated with supernatants from A1-positive cells.
  • (7) We have previously shown that serotonin is present in secretory granules of frog adrenochromaffin cells; concurrently, we have demonstrated that serotonin is a potent stimulator of corticosterone and aldosterone secretion by adrenocortical cells.
  • (8) Cyclic AMP stimulated phosphorylation by [gamma-32P]ATP of two proteins of apparent Mr = 20,000 and 7,000 that were concentrated in sarcoplasmic reticulum, but the stimulation was markedly dependent on the presence of added soluble cyclic AMP-dependent protein kinase.
