  • (4) L-menthol caused a highly significant enhancement of nasal sensation of airflow but despite their great similarity in structure and a similar peppermint smell the isomers D-isomenthol and D-neomenthol had no effect on nasal sensation of airflow.
  • (5) External application of 50 microM Ni2+ blocks the effect of CAP, but does not affect the acceleration of the high voltage-activated (L-type) current inactivation induced by menthol.
  • (6) The VAS scores showed significant changes of subjective improvement in nasal sensation of airflow (P less than 0.001) in the menthol-treated group 10 min after dosing whereas the placebo group showed no change.
  • (7) Angela Harbutt, campaigns manager of the smokers' group Forest, said: "Consumers will have mixed feelings.We welcome the fact that some products have been reprieved while menthol cigarettes have been given a stay of execution, but consumers are still angry that the EU is trying to restrict or ban products they have purchased and enjoyed for many years.
  • (8) The effect of menthol on Ca channel current inactivation was studied in identified Helix neurons.
  • (9) Since, in equal concentrations, menthol specifically impairs neuronal calcium currents, the results are consistent with the conjecture that in cold receptors, menthol reduces the activation of a calcium-stimulated outward current by an impeding effect on a calcium conductance, thereby inducing depolarization and a modification of bursting behavior.
  • (10) Application of the specific calcium channel blocker menthol (0.2 mM) suppressed spontaneous activity, the effect becoming more prominent at higher temperatures.
  • (11) In contrast, lingual fibers and a different category of cortical units ('Type II') were extremely sensitive to menthol exposure.
  • (12) TEST and TEST-menthol SSCSs produced negative results in all 5 bacterial strains, both with and without metabolic activation.
  • (13) The specificity of the Ca2(+)-channel blocking effect of menthol was demonstrated in parallel studies using compounds with similar structures: menthone blocked Ca2+ channels with about half the potency of menthol, while cyclohexanol was without effect.
  • (14) Thus, a proposed third type of Ca current with transient activation and complete deactivation below -50 mV was either not present or not affected by menthol.
  • (15) TEST and TEST-menthol CSCs were nonmutagenic in all five bacterial strains, both with and without metabolic activation.
  • (16) The effect of l-menthol on the skin permeability of mannitol, cortisone or indomethacin was examined by an in vitro penetration technique with hairless mouse skin.
  • (17) Over a couple of pints, we cover all the big stuff: Victoria Beckham, rivers of blood, what it'll be like being deputy PM to Boris ("Boris needs me; he needs lightening up"), and the attempt to ban menthol cigarettes .

  • (20) In the second study EtOH or a placebo was administered at 1530 across three days also in the presence of menthol.

Methol


Definition:

  • (n.) The technical name of methyl alcohol or wood spirit; also, by extension, the class name of any of the series of alcohols of the methane series of which methol proper is the type. See Methyl alcohol, under Methyl.

Example Sentences:

  • (1) Compositions of patch tests series varies with regard to the individual substances included: allergens with low sensitizing potency (methol, resorcin, methylsalicylate (!
  • (2) The program provides an efficient methol of obtaining spectoral information concerning the EEG without the associated cost or complexity of conventional power spectrum techniques.
