Background Enhanced recovery after surgery (ERAS) program is an effective evidence-based multidisciplinary protocol of perioperative care, but its roles in thoracic surgery remain unclear. This systematic review of randomized controlled trials (RCTs) aims to investigate the efficacy and safety of the ERAS programs for lung cancer surgery. Materials and methods We searched the PubMed and EMBAS...

Environmental risk assessment (ERA) is often considered as the most transparent, objective and reliable decision-making tool for informing the risk management of chemicals and nanomaterials. ERAs are based on the assumption that it is possible to provide accurate estimates of hazard and exposure and, subsequently, to quantify risk. In this paper we argue that since the quantification of risk is...

Background The Enhanced Recovery After Surgery (eras) colorectal guideline has been implemented widely across Alberta. Our study examined the clinical and cost impacts of eras on colon cancer patients across the province. Methods We first used both summary statistics and multivariate regression methods to compare, before and after guideline implementation, clinical outcomes (length of stay, com...

A tumorigenic culprit in ES cells n the debate over whether ES cells or somatic stem cells have better prospects for stem cell therapies, ES cell proponents admit that their pluripotent cells carry an increased risk: ES cells can form teratomas. have found that a newly discovered Ras gene may be at the heart of this problem. ERas, previously thought to be a pseudogene, was found by the group as...

marriage and mate selection is one of the most important events in the social life which has been observed in various forms in different eras and societies. to achieve this, using qualitative content analysis, all marriages mentioned in the shahnameh were analyzed. the results show that the kings and heroes as the class of iranian society in the shahnameh, for finding a matching partner, person...

Scanning thermal microscopy has been implemented in a cross-sectional geometry, and its application for quantitative, nanoscale analysis of thermal conductivity is demonstrated in studies of an ErAs/GaAs nanocomposite superlattice. Spurious measurement effects, attributable to local thermal transport through air, were observed near large step edges, but could be eliminated by thermocompression ...

We report the fabrication and characterization of segmented element power generator modules of 16 x 16 thermoelectric elements consisting of 0.8 mm thick Bi2Te3 and 50 μm thick ErAs:(InGaAs)1-x(InAlAs)x with 0.6% ErAs by volume. Erbium Arsenide metallic nanoparticles are incorporated to create scattering centers for middle and long wavelength phonons, and to form local potential barriers for el...
