In this study we quantitated the region of preserved myocardium between a subendocardial myocardial infarct (SEMI) and the endocardium in dogs and determined whether this preserved zone was within the region at risk and whether infarct extension could occur in this region. We also evaluated whether a similar subendocardial region exists in patients with SEMI. A 40-minute temporary occlusion of ...

INTRODUCTION Open, right-sided, transthoracic esophagectomy with one-lung ventilation (OLV) triggers a massive inflammatory reaction. The influence of the OLV on the inflammatory cascade is unclear. Data on the inflammatory response in the ventilated left and collapsed right lung, respectively, are scarce. The aim of this study was to analyze this reaction in bronchoalveolar lavage (BAL) fluid ...

A numerical investigation has been carried out for mixed convection flow in a rectangularventilated cavity with a heat conducting solid circular cylinder at the center. Forced convection flowconditions were imposed by providing an inlet at the bottom of the left wall and an outlet vent at the topto the other sidewall. In this paper, the effect of cavity aspect ratio as well as the mixed convect...

The objective of this work is to study the effect thickness a porous separation on thermal performance in cavity with displacement ventilation. cold air jet enters and exits through two openings located lower upper parts left wall right respectively. other horizontal walls are also adiabatic. hydrodynamic characteristics transfer were studied for three configurations same aspect ratio L/H=2. he...

PURPOSE Mechanically ventilated patients are at risk for developing ventilator-associated pneumonia, and it has been reported that dental plaque provides a reservoir of respiratory pathogens that may aspirate to the lungs and endotracheal tube (ETT) biofilms. For the first time, metataxonomics was used to simultaneously characterize the microbiome of dental plaque, ETTs, and non-directed bronch...

The understanding of the internal gaseous flow artificially ventilated supercavities is developed using a locally homogenous, multiphase computational fluid dynamics model that benchmarked experimental data. solutions indicate gas leakage from supercavity originates shear layers forming at gas-water interface. Not only do these observations corroborate previous theory for cavities with toroidal...

Accurate values for the climatic conditions in an air cavity, hereby called microclimate, are crucial when calculating and simulating performance of a ventilated roof façade system. The stress its components their mould rot potential influence long-term durability or façade. A scoping study is conducted to gain overview on research scientific literature microclimate cavities roofing claddings N...
