BACKGROUND The purpose of this study was to examine the relationship between 2005-2006 National Health and Nutrition Examination Survey (NHANES) accelerometer-determined steps/day and activity counts/day, and between steps/day and estimates of nonwear time (as an indicator of the unmonitored day) and time spent in sedentary behaviors as well as a range of physical activity intensities.

Concentrations of 27 commonly estimated serum constituents were measured in blood sampled from 20 apparently healthy volunteers at 0830, 1230, and 1630 hours on each of four days, at weekly intervals. Time-dependent statistically significant (p less than or equal to 0.01) variation was observed in 12 of the constituents. The 15 constituents that showed no statistically significant diurnal varia...

background pycnocycla spinosa decne. ex boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. thirty four components have been extracted from p. spinosa essential oil, of which several major constituents were found to show seasonal variation. objectives the aim of this work is to evaluate the diurnal variation of its oil constituents...
