Individual experiments may yield inaccurate MAC estimates. This inaccuracy is minimized as the number of crossovers increases; however, improvement diminishes as the number of crossovers exceeds six.

This study investigates the influence of students' perceptions on mathematics performance at a selected South

A substantial proportion of patients with chronic type B dissection who receive initial medical management will later need surgery. Long-term treatment with beta-blockers reduces the progression of aortic dilatation, the incidence of subsequent hospital admissions, as well as the incidence of late dissection-related aortic procedures and the cost of treatment. Patients with chronic type B dissection need, in addition to frequent follow-up of aortic diameter, continuous treatment with beta-blocking agents.

Our results suggest a dose-dependent impairment of central processing of auditory information after propofol administration. These results are consistent with electrophysiological findings measuring neuronal activity directly, thus suggesting a dose-dependent impairment of central processing of auditory information after propofol administration. However, propofol did not totally blunt primary cortical responses to acoustic stimulation, indicating that patients may process auditory information under general anaesthesia.
