  • (17) 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.
  • (18) We conjecture that the efficacy of radioimmunoconjugates against responsive cell types may be the result of passive DNA damage by ionizing radiation and the initiation of apoptosis in response to radioimmunotherapy.
  • (19) But the fact that the ability to create new explanations is the unique, morally and intellectually significant functionality of "people" (humans and AGIs), and that they achieve this functionality by conjecture and criticism, changes everything.
  • (20) Since nafenopin pretreatment stimulates the synthesis of new liver tissue, it is presently a matter of conjecture as to whether or not the newly formed hepatocytes have the capacity to take up and excrete BP and its metabolites or whether nafenopin inhibits transport in all liver tissue.
