[1] The atmospheric limb sounding technique making use of radio signals transmitted by the Global Positioning System (GPS) has already proven to be a promising approach for global atmospheric measurements. In this study, we assess for the first time the potential of GPS radio occultation soundings for detecting the migrating diurnal tide. Retrieved temperatures between 10 and 30 km in the tropi...

KAKOLEWSKI, JAN W., EDWARD DEAUX, JANICE CHKISTENSEN, AND BAWAI~A CASE. LXurnal patterns in water and food intake and body ~c&ht changes in rats xith hypothalamic leszbns. Am. J. Physiol. 22 l(3) : 7 1 l-7 18. 1971 .-The diurnal patterns of water and food intake, water-to-food ratio, and body weight changes were examined in rats with bilateral hypothalamic lesions and intact control rats of the...

PURPOSE To determine the diurnal and nocturnal effects of travoprost with sofZia(®) (Travatan Z(®) [TZ]) on intraocular pressure (IOP) and ocular perfusion pressure (OPP) in patients with normal-tension glaucoma (NTG). METHODS Twenty-seven subjects with NTG were admitted to an inpatient sleep laboratory for three 24-hour sessions monitoring IOP, blood pressure (BP), and heart rate every 2 hou...

Fatigue is a challenge in ovarian cancer survivorship and greatly impacts quality of life. In other cancer populations, fatigue has been associated with abnormal diurnal cortisol patterns. However, little is known about biological and behavioral factors in 5+-year ovarian cancer survivors and potential mechanisms underlying persistent fatigue have not been investigated in this population. Moreo...

PURPOSE This study sought diurnal variations of eye length in human subjects, analogous to those reported in laboratory animals. METHODS Seventeen subjects, ages 7 to 53 (median 16) years and mean spherical equivalent refractive error -0.68 D (range, -3.00 to +1.00 D), underwent axial length measurements at multiple times during the day between 7 AM and 1 AM the following day, using partial c...

Introduction Ventricular septal defect (VSD) is the most common congenital heart defect, with larger VSDs typically being corrected with an open-heart surgery during infancy. Long-term consequences of a VSD-corrective surgery on stress systems of child and mother are still unknown. The aim of the present study is to investigate the associations of an early corrected VSD and diurnal cortisol rel...

The eastward propagating Madden-Julian Oscillation (MJO) typically exhibits complex behavior during its passage over the Maritime Continent, sometimes slowly propagating eastward and other times stalling and even terminating there with large amounts of rainfall. This is a huge challenge for present-day numerical models to simulate. One possible reason is the inadequate treatment of the diurnal ...

PURPOSE There is growing evidence that the hypothalamic-pituitary-adrenal axis plays a role in the progression of cardiovascular disease. We examined the relationship between diurnal cortisol rhythm and adverse events in patients undergoing coronary artery bypass graft (CABG) surgery. We hypothesized that a flatter presurgical diurnal cortisol slope would be associated with higher rates of adve...

The present study compared the cortisol awakening response and diurnal rhythm in 24 young healthy students and 48 community-dwelling older adults. The associations with diurnal cortisol and depression, anxiety and social support were also examined in relation to age. Salivary cortisol was measured over the course of one day: immediately upon awakening, 30 min later, and then 3h, 6h, 9h and 12h ...

BACKGROUND The loss of diurnal rhythm in blood pressure (BP) is an important predictor of end-organ damage in hypertensive and diabetic patients. Recent evidence has suggested that two major physiological circadian rhythms, the metabolic and cardiovascular rhythms, are subject to regulation by overlapping molecular pathways, indicating that dysregulation of metabolic cycles could desynchronize ...
