Does sympathetic withdrawal augment cerebral blood flow during acute hypercapnia in sleeping lambs?
Hypercapnia increases CBF in sleep and wakefulness, with the increase being greatest in REM. Sympathectomy increases baseline CBF, but decreases the response to hypercapnia. These findings suggest that cerebral sympathetic nerve activity is normally withdrawn during hypercapnia in REM sleep, augmenting the CBF response.
While sCD163 level in psoriatic patients was diminished after GT therapy, CD163 expression on monocytes was altered only to a minor extent.
