The NCEP/NCAR pentad mean reanalysis data from 1980 to 1994 are employed to examine the activities of the 100 hPa South Asia High (SAH) during the boreal summer. The results show that there exists bimodality in the longitude location of the SAH. According to the two preferred regions for the SAH, the SAH is classified into the Tibetan Mode (TM) and the Iranian Mode (IM), respectively. The studi...

OBJECTIVE Chronic stress may be a risk factor for coronary heart disease and is associated with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. We tested the hypotheses that two markers of HPA axis dysregulation, elevated average level (area under the curve, adjusted for time awake) and diurnal decline of salivary cortisol, were associated with presence of coronary calcification...

in this investigation, 25 adult new zealand white rabbits randomly selected from both sexes and studied.coloured latex injection and corrosion cast methods were applied on the materials. this study was carried out to disclose the distribution of the cardiac veins of the new zealand white rabbits. the veins that drain the heart were found to be the great cardiac vein, the middle cardiac vein, th...

OBJECTIVE To define the current standards of donor right hepatectomy, including the middle hepatic vein for adult-to-adult live donor liver transplantation. SUMMARY BACKGROUND DATA Donor morbidity and mortality are inevitable given the ultra-major nature of the donor operation. Results from a matured center could define the true impact of this donor procedure most accurately. PATIENTS AND M...

[1] Vertical structure and evolution of the wintertime Northern Hemisphere Annular Mode (NAM), the first Empirical Orthogonal Function (EOF) of geopotential height anomalies, are constructed from the 2005–2009 Aura Microwave Limb Sounder (MLS) measurements in the entire middle atmosphere between 316 hPa ( 9 km) and 0.001 hPa ( 90 km). This is the first report of NAM structure extending into the...

A possibly new teleconnection has been discovered off the east coast of Australia in the region around Tasman sea and Southern Ocean. Found in pressure anomalies using a novel graph based approach called shared reciprocal nearest neighbors, this dipole appears in reanalysis datasets such as NCEP, JRA, ERA and MERRA. The HadSLP2 observation data shows the new dipole, despite of limited observati...

Glucocorticoid negative feedback regulation of the hypothalamic-pituitary-adrenal (HPA) axis is mediated by corticosteroid receptors. It is widely thought that during stress, glucocorticoid receptors (GR) are essential for this negative feedback. In contrast, mineralocorticoid receptors (MR) are associated with HPA axis regulation in basal, nonstress conditions. Notions about the relative roles...

[1] Global measurements of the 500–825 hPa layer mean HDO/H2O ratio from the Tropospheric Emission Spectrometer (TES) are used to expose differences in the dominant hydrologic processes in the Amazon, north Australian, and Asian monsoon regions. The data show high regional isotopic variability and numerous values unexpected from classical Rayleigh theory. Correlation analysis shows that mixing ...
