(2) "It looks as if the noxious mix of rightwing Australian populism, as represented by Crosby and his lobbying firm, and English saloon bar reactionaries, as embodied by [Nigel] Farage and Ukip, may succeed in preventing this government from proceeding with standardised cigarette packs, despite their popularity with the public," said Deborah Arnott, chief executive of the health charity Action on Smoking and Health.
(3) Noxious conditioning stimulation of a tooth led to a temporary decrease of the threshold for the jaw-opening reflex elicited from a contralateral or adjacent tooth; only conditioning stimulation at an intensity producing a marked arousal reaction was effective in this respect.
(4) Results showed the greatest inhibition of noxious stimulus perception with Innovar-Vet, lesser inhibition with ketamine-xylazine and ketamine-diazepam, and the least obtunding of nociception with pentobarbital.
(5) Furthermore the noxious stimuli were completely ineffective from 10-15 min following the lidocaine injection while the non-noxious stimuli maintained their efficacy.
(6) Experiments using normal human subjects were performed to determine the effect of a putative analgesic, transcutaneous electrical nerve stimulation (TENS), on the perception of noxious thermal stimuli and also to examine critically the general applicability of signal detection theory (SDT) to the evaluation of analgesic agents.
(7) Rats inoculated in the tail-base with killed Mycobacterium butyricum developed an arthritic swelling and inflammation of the limbs accompanied by a hyperalgesia to noxious pressure applied thereto.
(8) Complete transection of the thoracic spinal cord eliminated both thermally elicited responses and orienting responses to noxious and tactile mechanical stimulation of the hindlimbs.
(9) This situation has contributed to exposure of sandblasters to hazardous levels of respirable free silica, and is reviewed here to prevent a continuation of the incompatibility of these and other standards for respiratory protection with the actual exposures to various noxious inhalants in the workplace.

(14) Neurons were first classified as on-cells if they fired faster during noxious pinch or as off-cells if they fired slower.
(15) These data indicate the antinociception from PAG stimulation is not equally distributed throughout the body, and that the intensity of the noxious stimulus influences the threshold for SPA.
(16) Profound inhibitions of the second phase were also produced by tactile segmental stimulation and noxious stimuli applied to widespread areas of the body (diffuse noxious inhibitory controls).

(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.
