This study aimed to examine the effects of different taping pressures with or without external force on the maximum dorsal flexion angle (DFA). Twenty-two healthy male university students with >5 years of athletic experience participated. A qualified trainer wound a rigid tape thrice around subject’s wrist joint. Taping pressure was measured using the pressure measuring system AMI3037-SB. Indep...

BACKGROUND Advanced glycation end products (AGEs), inflammatory-associated macrophage migration and accumulation are crucial for initiation and progression of diabetic vascular complication. Enzymatic activity of heparanase (HPA) is implicated strongly in dissemination of metastatic tumor cells and cells of the immune system. In addition, HPA enhances the phosphorylation of selected signaling m...

We examined the seasonal variations of isotopic composition of water vapor in the lower troposphere (850–500 hPa) to relate those of precipitation and groundwater using satellite observations from the Aura Tropospheric Emission Spectrometer (TES) over the volcanic Island of Jeju, Korea. We ran an isotope-enabled general circulation model (IsoGSM) and calculated 120-hr reversecalculated trajecto...

Abstract Background and Objectives Following incompatible blood transfusions, anti-HLA and  anti- HPA antibodies may develop and cause various disorders such as post-transfusion purpura, platelet refractoriness, and thrombocytopenia leading to bleeding. The aim of this study was to investigate platelet antigens and antibodies in multi-transfused patients.   Materials and Methods In this desc...

Abstract A cloud is a collection of water droplets or ice crystals, both them suspended in the air. The aim this work to study spatiotemporal variations properties over six selected cities Iraq which they are (Mosul, Khanaqin, Baghdad, Rutba, Kut, and Basra) at multi-pressure levels using remote sensing data for period from (1981) (2020). results show that values temperature specific humidity a...

To study the Iran precipitation anomaly in September to November of 2016 and its probable connection with ENSO (El Nino-Southern Oscillation). This period with similar cases in the previous 55 years (1964, 1983, and 1995 according to forecasting center of NOAA) was investigated. In all cases, ENSO changed from strong El-Nino to weak La-Nina after a very brief neutral period. In the following, o...

By using the daily average wind speed and precipitation data of 125 stations in Jiangsu Anhui Provinces China from 1961 to 2020 monthly NCEP/NCAR reanalysis data, interannual variation characteristics its possible reasons spring compound extreme events Jiangsu–Anhui region were discussed. Results show that generally present a lesser distribution south more north. The occurring (north) 32° N are...

Rainfall behavior is a fundamental issue in areas with scarce and irregular amounts, such as the Spanish Mediterranean region. We identified 12 spatial patterns that characterized 899 torrential precipitation events (≥150 mm 24 h) occurred 3,537 rainy series period 1950–2020. Three of these components––eastern ESE––showed positive significant trends their accumulated volumes. then mean synoptic...

The Ural blocking (UB) high is a weather system closely related to the cold air process during winter, which could trigger extreme events in East Asia. By retrieving five single indexes, including accumulation frequency, central latitude, intensity, mean duration and north rim, it found that UB winter occurs more frequently, grows stronger, lasts longer located northward after 2002, compared wi...

Using monthly gridded 500-hPa data, two synoptic indices are defined to better understand the principle mechanisms controlling intraseasonal to multiannual winter climate variability in New England (NE). The ‘‘trough axis index’’ (TAI) is created to quantify the mean longitudinal position of the common East Coast pressure trough, and the ‘‘trough intensity index’’ (TII) is calculated to estimat...
