Blockade1

  • Scratch commands can renew skin inflammation without skin contact

    Where this hypothesis actsPeripheral signaling associated with cutaneous mast-cell activation during scratch motor bouts

    What is proposedBlock peripheral substance-P receptor activity

    With whatNot stated in the record

    HowPeripheral substance-P receptor blockade; no specific blocking agent is stated

    Possible resultPossible interruption of inflammation while scratch motor bouts continue

Function restoration1

  • Repeated climate transitions may destabilize heat loss by reducing vascular receptor sensitivity

    Where this hypothesis actsDuring repeated transitions between humid heat and dry cool conditions

    What is proposedAllow receptor responsiveness to recover between successive stimuli

    With whatChange of environment or regimen

    HowMatch the stimulation interval to the time needed for receptor responsiveness to recover

    Possible resultPossible stabilization of heat dissipation and SPV_8 across repeated transitions
