BACKGROUND: Arterial stiffness is at least partially controlled by vascular tone. Vascular tone and underlying physiological processes, e.g. sympathetic activity, have been shown to follow diurnal variations. METHODS: This study investigated whether arterial stiffness and perfusion of subendocardial myocardium relative to cardiac workload show diurnal variations under physiological conditions. The ...

Carbohydrate-deficient transferrin (CDT) was quantified in 408 blood specimens, randomly selected from 1260 drivers apprehended and submitted to blood alcohol concentration (BAC) determination. The first step of the study was to observe whether a BAC based pre-evaluation was relevant for deciding to test drivers for chronic alcohol abuse. For this ...
