The concept of a dew-point front was introduced, and its existence was identified near the periphery of the west Pacific subtropical anticyclone by using the daily 1 1 data of the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR). The dew-point front was a transitional belt between the moist southwest monsoon flow and the dry adiabatic sinking flo...
The Kuroshio and its extension (KE) significantly influences regional climate through meridional heat transport from the tropical ocean. In this study, observational reanalysis datasets are used to investigate impact of latent flux (LHF) over KE region on downstream rainfall underlying mechanism. result shows a “seesaw” structure in anomaly, dominating Western Canada southwestern North America ...
چکید ه سابقه و هدف روش های سرولوژیکی جهت تعیین نوع آنتی ژن های پلاکتی به دلیل محدودیت دسترسی به منابع آنتی سرم های اختصاصی و تعداد ناکافی پلاکت در بیماران مبتلا به ترمبوسیتوپنی محدود شده است. بنابراین از روش های مولکولی و بر پایه dna جهت تعیین ژنوتیپ آنتی ژن های پلاکتی استفاده می شود. از آن جا که در مورد میزان شیوع این آنتی ژن ها در جمعیت ایران اطلاعات چندانی در دسترس نیست لذا هدف مطالعه، ت...
The synoptic scale features over the eastern Mediterranean (EM) for July–August are examined using National Centers for Environmental Prediction–National Center for Atmospheric Research reanalysis data. The region is subjected to two primary factors: mid–upper level subsidence and lower level cool advection, associated with the Etesian winds. The interdiurnal variations of these factors were fo...
OBJECTIVE The objective of this study was to evaluate the frequencies of human platelet antigens in oncohematological patients with thrombocytopenia and to analyze the probability of their incompatibility with platelet transfusions. METHODS Platelet antigen genotyping was performed by sequence-specific primer polymerase chain reaction (SSP-PCR) for the HPA-1a, HPA-1b, HPA-2a, HPA-2b, HPA-3a, ...
Abstract This study presents an analysis on the storm environmental features during first recorded tornado outbreak in modern history of China August 13–14, 2018. Eleven reported tornadoes were spawned within a 20‐hr period by Typhoon Yagi (1814) its dissipating stage after landfall. They primarily formed when was at relatively weak intensity. Six generated that had lost intensity as tropical d...
Cognitive deficits and hippocampal atrophy, features that are shared with aging and dementia, have been described in type 2 diabetes mellitus (T2DM). T2DM is associated with obesity, hypertension, dyslipidemia, hypothalamic pituitary adrenocortical (HPA) axis abnormalities and inflammation, all of which have been shown to negatively impact the brain. However, since most reports in T2DM focused ...
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...
[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...
