(9) The effects of norepinephrine (NE), histamine (HIST), glutamate, and adenosine, singly and in combinations, on the accumulation of adenosine 3',5'-monophosphate (cyclic AMP) in slices of rabbit cerebral cortex were examined using tissue from animals 4 days before to 38 days after birth.
(10) The present studies were undertaken to obtain histamine (HIST) dose-response curves for tracheal smooth muscle (TSM) from an actively ragweed-sensitized canine model of asthma and to compare these results with 1) HIST dose-response data from littermate control dogs, 2) initially nonsensitized TSM passively sensitized (in vitro) to ragweed and 3) the dose-response curve to an agonist that opens primarily voltage-sensitive calcium channels, i.e., K+.

(12) The presence of Campylobacter pylori was investigated in duodenal, antral and fundic biopsies of 149 consecutive patients undergoing upper gastrointestinal tract endoscopy by biopsy urease tests (CLOtest; "CLO test") and histologic examination ("HIST") after modified Giemsa staining.
(13) On the other hand, pretreatment of the muscle with 10(-5) M Hist for 10 min did not influence the contraction by either MeCh or Hist.
(14) After pretreatment of the muscle with 10(-5) M MeCh for 10 min, the contractile effect of 10(-5) M Hist was suppressed intensely for a certain time period, but that of 10(-5) M MeCh was not diminished.
(15) Hist and Gast caused an increase of PGE2 contents in gastric mucosa.
(16) Subclones containing restriction fragments from plasmid psi 300 inserted downstream from the lac promoter established that the hisT gene is oriented from the HindIII site toward the ClaI site.
(17) This mutation is linked to purF, suggesting that it is a new allele of hisT.
(18) The hisT gene codes for an enzyme responsible for the conversion of uridine to pseudouridine (Psi) in the anticodon region of many tRNA species in Salmonella typhimurium.
(19) Furthermore, this suppression was not surmounted by the elevation of Hist concentration.
(20) In general, HIST was found as most sensitive and effective.

Example Sentences:
(1) This study was part of a larger study, which included development of a theoretical model for creation of items for the PSST.
(2) Children and families were assigned randomly to 1 of 3 conditions: PSST, PMT, or PSST and PMT combined.
(3) PSST and PSST-P children showed significantly greater reductions in antisocial behavior and overall behavior problems, and greater increases in prosocial behavior than RT children.
(4) This study evaluated the effects of problem-solving skills training (PSST) and parent management training (PMT) on children (N = 97, ages 7-13 years) referred for severe antisocial behavior.
(5) It was predicted that (a) each treatment would improve child functioning (reduce overall deviance and aggressive, antisocial, and delinquent behavior, and increase prosocial competence); and (b) PSST and PMT combined would lead to more marked, pervasive, and durable changes in child functioning and greater changes in parent functioning (parental stress, depression, and overall symptoms).
(6) Children were randomly assigned to one of three treatments: problem-solving skills training (PSST), problem-solving skills training with in vivo practice (PSST-P), which included therapeutically planned activities to extend training to settings outside of treatment, or client-centered relationship therapy (RT).
