Insufficient sleep and circadian rhythm disturbances have been each associated with adverse cardiovascular outcomes in epidemiological studies, but experimental evidence for a causal link is scarce. The present study compares the impact of circadian misalignment (CM) to circadian alignment (CA) on human autonomic function using a nonrandomized parallel group design to achieve the same total sle...

In a randomised trial of artificial surfactant (ALEC) given at birth to 294 babies less than 34 weeks' gestation, the respiratory compliance was measured at 1, 6, 24, 48, and 168 hours after birth. In babies less than 29 weeks' gestation ALEC significantly improved the mean (SEM) compliance at 6 hours from 0.54 (0.06) to 0.91 (0.13) ml/cm H2O/kg and at 24 hours from 0.57 (0.04) to 0.92 (0.10) m...

The use of noninvasive methods for measuring fecal glucocorticoid metabolites is a useful tool for endocrine assessment particularly in studies where animals cannot be captured, when they should be sampled without disturbing their activities, and/or when welfare needs to be maximized. However, still no complete standardization exists for the methodology, and some confounding variables may play ...

The rate of movement for 3and 10-cm-high granule ripples was documented in September of 2006 at Great Sand Dunes National Park and Preserve during a particularly strong wind event. Impact creep induced by saltating sand caused 24 granules min 1 to cross each cm of crest length during wind that averaged 9 m s 1 (at a height well above 1 m), which is substantially larger than the threshold for sa...

OBJECTIVE To evaluate long-term cyclic and continuous administration of oral contraceptive pills (OCP) in preventing ovarian endometrioma recurrence after laparoscopic cystectomy. DESIGN Prospective, randomized, controlled trial. SETTING Tertiary care University Hospital. PATIENT(S) Two hundred thirty-nine women who underwent laparoscopic excision of ovarian endometriomas. INTERVENTION(...

BACKGROUND Immunoglobulin E-mediated allergy to cow's milk protein (CMP) tends to subside over years of follow-up. The gold standard for detecting such allergy has been the oral challenge test. The development of some other test for determining the correct timing of the oral challenge test would avoid unnecessary patient discomfort. The aim of this study was to determine whether monitoring cow'...
