Although morphological studies suggest that coronary vascular injury is a result of prolonged ischemia and subsequent reperfusion, whether functional coronary microvascular injury develops during brief in vivo ischemia is unclear. In other organs, permeability is a sensitive indicator of functional vascular injury. Therefore, a new double-indicator method of assessing vascular protein permeabil...

An index of pulmonary epithelial permeability has been studied in 12 patients with chronic renal failure during haemodialysis. It was assessed by the half time clearance from lung to blood (t 1/2 LB) of a nebulised solution containing technetium labelled diethylene triamine pentacetic acid (99mTc DTPA). Six patients were cigarette smokers and six were non-smokers. The non-smokers had greater pr...

with the history of cardiac surgery, there may be difficulty in finding the reference to a particular point. Usually, however, the major points are indexed and it is only ones ancillary to cardiac surgery that one must search for. The margins are liberally sprinkled with line drawings of many of the pioneers. The sketches add charm to the presentation, even though they are not always good liken...

permeability is a property of porous medium that quantifies rock capacity to transmit fluids. frequently, core based permeability data are not available either because of the borehole conditions or due to the high cost of coring. for these reasons, over the years attempts have been made to estimate permeability by alternative ways. permeability is an elusive parameter in hydrocarbon reservoirs ...

We show the feasibility of controlling the magnetic permeability of optical semiconductor devices on InP-based photonic integration platforms. We have achieved the permeability control of GaInAsP/InP semiconductor waveguides by combining the waveguide with a metamaterial consisting of gate-controlled split ring resonators. The split-ring resonators interact magnetically with light travelling in...

I echo the call for a real change in the diagnosis of acute respiratory distress syndrome (ARDS), as put forward in the recent editorial by Phillips [1]. Whilst there are real limitations regarding availability, feasibility and interpretation of extravascular lung water (EVLW), it remains one of the few clinically available quantitative parameters for assessment of the severity of lung injury. ...

In this work, we incorporated the effects of slippage and adsorption into transient productivity index to determine pressure in horizontal wells simulation natural gas reservoirs. We modeled by introducing an apparent permeability, a function Knudsen number, while is using Langmuir isotherm. As for index, included one classic Peaceman reservoir-coupling models, which integral exponential polyno...
