Is circadian rhythm of heart rate variability reversibly abolished in ischemic stroke?
These results suggest that circadian fluctuation of heart rate variability is reversibly abolished in the acute phase of ischemic stroke and that it returns during the subsequent 6 months. The loss of the relative vagal nocturnal dominance may contribute to the incidence of cardiac arrhythmias and other cardiovascular complications after acute stroke.
Rhinovirus has the unique ability to bypass antigen presentation and directly infect and activate human T cells. This could explain the strong association of rhinovirus with exacerbation of airway diseases.
