Does peak systolic velocity Doppler index reflect most appropriately the dynamic time course of intact cerebral autoregulation?
Our data show peak systolic blood flow velocity index to be most accurate for measuring effectiveness of the dynamic CA mechanism. No differences in the CA were found between the vascular territory of the middle and posterior cerebral arteries.
Quantitative trait analysis based on a limited number of genetic markers suggests that estrogen-related genes mainly regulate sperm concentration and motility.
