In vitro models of the liver microvasculature, especially with respect to cancer cell extravasation, should include not only endothelial and cancer cells but also surrounding cells to mimic the physiological situation. To this end, in the present study, we established a physiologically-relevant hierarchical co-culture model by stacking layers of primary rat hepatocytes (Hep), hepatic stellate cells embedded in collagen gel (LX-2) and endothelial cells (HUVECs) on a specially designed oxygen-permeable polydimethylsiloxane PDMS bottom plate...

Vascular adhesion protein-1 (VAP-1) is a unique molecule since it acts as an adhesion molecule as well as an ectoenzyme catalyzing oxidative deamination of primary amines and generates hydrogen peroxide in the extracellular space. While VAP-1 is implicated in various inflammatory diseases, its role in acute kidney injury is less characterized. Here we studied VAP-1 expression in the kidney and the effect of its inhibition in a rat model of renal ischemia/reperfusion injury. VAP-1 was predominantly expressed in pericytes, which released enzymatically active enzyme...

We develop a geometrical optimization technique for the projection-after-variation (PAV) scheme of the recently refined projected Hartree-Fock (PHF) as a fast alternative to the variation-after-projection (VAP) approach for optimizing the structures of molecules/clusters in symmetry-adapted electronic states at the mean-field computational cost. PHF handles the nondynamic correlation effects by restoring the symmetry of a broken-symmetry single reference wavefunction and moreover enables a black-box treatment of orbital selections...

This study evaluated the effectiveness of an educational course that aimed to expand student nurses' knowledge about the guidelines for ventilator-associated pneumonia (VAP) prevention. In the pretest, the students revealed poor knowledge (mean score ± SD, 6.3 ± 2.8 out of 20). After completion of the educational program, participants in the experimental group showed a significant improvement (t105 = 14.9, P < .001). The control group showed no significant improvement. More focus on VAP prevention guidelines is essential in nursing curricula...

BACKGROUND: In patients with traumatic brain injury (TBI), ventilator-associated pneumonia (VAP) is considered a dangerous complication, prompting early aggressive antibiotic treatment and prophylaxis. While this approach increases the selection of multidrug-resistant bacteria (MDR), its clinical benefit has not been demonstrated. METHODS: One-year incidence of VAP in severe TBI patients (ICU stay >48 hours, with either Glasgow Coma Scale 8 or receiving intracranial pressure monitoring, or having undergone emergency surgery) and the prevalence of MDR among those who eventually developed it, were compared in two Italian intensive care units (ICUs) adopting different antibiotic approaches...

International best practice endorses the use of standardized approaches in the management of pediatric patients in the Pediatric Intensive Care Unit (PICU). There is increasing awareness of the risk of prolonged duration of mechanical ventilation as a consequence of morphine use leading to ventilator associated pneumonia (VAP), extended PICU and hospital length of stay and increased morbidity and mortality. Accordingly a fundamental outcome measure of this study was to determine whether raising awareness of these issues and the introduction of analgesia and sedation guidelines led to a reduction in the amount of analgesics and sedatives administered to PICU patients, while not exposing them to pain and distress...
