BACKGROUND Occludin, a tight junction protein, plays an important role in maintaining the integrity of the lung epithelial barrier; however, its role in ventilation-induced lung injury has not been explored. Here, we measured the expression of occludin with different tidal volumes. Our study indicated that the level of occludin was significantly decreased and alveolar permeability was increased...
BACKGROUND High tidal volume ventilation has shown to cause ventilator-induced lung injury (VILI), possibly contributing to concomitant extrapulmonary organ dysfunction. The present study examined whether left ventricular (LV) function is dependent on tidal volume size and whether this effect is augmented during lipopolysaccharide(LPS)-induced lung injury. METHODS Twenty male Wistar rats were...
The effects of tides on littoral marine habitats are so ubiquitous that shorelines are commonly described as 'intertidal', whereas waves are considered a secondary factor that simply modifies the intertidal habitat. However mean significant wave height exceeds tidal range at many locations worldwide. Here we construct a simple sinusoidal model of coastal water level based on both tidal range an...
Tidal basins are described by major features such as tidal flat, tidal channel, intertidal area, and tidal prism, which have been formulated by some empirical relations based on field observations. Although empirical relations explain some morphological patterns, those are not applicable to all conditions. Due to the lack of observations for different areas and under different geophysical condi...
our previous studies demonstrated the preventive effect of nigella sativa extract on asthma and water-soluble substances of this extract, especially its methanol fraction were responsible for this relaxation on contracted tracheal chains of guinea pigs. for the first time, the present study has been conducted to determine the main constituents of its methanolic extract. four constituen...
The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations. Tide models under review include empirical, purely hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten domin...
Since 2008 a network of five sea-level monitoring stations was progressively installed in French Polynesia. The are autonomous and data, collected at sampling rate 1 or 2 min, not only recorded locally, but also transferred real time by radio-link to the NOAA through GOES satellite. new ET34-ANA-V80 version ETERNA, initially developed for Earth Tides analysis, is now able analyze ocean tides re...
