Background The association between alcohol and blood pressure (BP) may be related to the temporal sequencing of alcohol use and BP measurement. We investigated the effects of single and repeated intakes of alcohol on 24-hour BP. Methods and Results Fourteen male habitual drinkers with essential hypertension were placed sequentially on a 4-day control phase: a nonalcoholic drink with the same ca...

BACKGROUND Quantitative numerical analysis of skin displacement triggered by muscles inserting the overlaying skin would be useful for monitoring the inhibition of mimetic muscles. METHODS By using removable grid markings and digital photographs, skin displacement analysis (SDA) was performed on 13 patients pre-treatment and on Days 1, 2, 3, and 7 after injection of 18 units of botulinum toxi...

PATIENTS AND INTERVENTIONS 70 procedures in 68 children (median age at intervention 6 years, median interval after conduit insertion 3.4 yea...

Using 400 days of new X-ray monitoring of M82, we confirm the 62 day periodicity previously reported. In the full data set spanning 1124 days, we find a period of 62.0± 0.3 days and a coherence, Q = 22.3, that is consistent with a strictly periodic signal. We estimate that the probability of chance occurrence of our observed signal is 6× 10. The light curve folded at this period is roughly sinu...
