Even in AF, we still need to know much more on the relation to stroke onset, ...
متن کاملDiurnal variation in the nitrate content of parsley foliage
The diurnal fluctuation of nitrate concentration in the foliage of three parsley subspecies (plain-leafed, curly-leafed and turnip rooted parsley) cultivated in the spring and autumn of two consecutive years was examined.

Rhythmic changes in blood pressure, hormones, and other parameters have been suggested as underlying mechanisms, but exogenous factors such as increasing physical activity after awakening may also be of relevance. To characterize the impact of external clock changes on the rhythmic variation in stroke on...
