Patient-prosthesis mismatch (PPM) was reported for the first time by Rahimtoola [1] in 1978 and it occurs when the effective orifice area (EOA) indexed for the body surface area (BSA) is less than that of a normal human valve. Several studies using the indexed EOA have shown the negative impact of PPM on clinical outcomes: in fact, it seems to be related with less improvement in symptoms, i.e. ...

Background: Microvascular obstruction (MO) is a pathophysiologic complication of acute myocardial infarction that portends poor prognosis; however, it transient and disappears with infarct healing. Much remains unknown regarding its pathophysiology whether there are predictors MO could function as stable surrogates. We tested for clinical cardiovascular magnetic resonance to gain insight into f...

in this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. for this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (swcnt) were inserted in the reaction layer. the performance of gas diffusion electrodes for oxygen reduction re...

the starting behavior of a supersonic axisymmetric mixed compression air intake was numerically investigated. the code solves reynolds-averaged navier–stokes equations using an explicit finite volume method in a structured grid by the roe flux difference splitting scheme. further, it uses the baldwin–lomax algebraic model to compute the turbulent viscosity coefficient. the correct method of sur...
