431, P=0.185, respectively). Similarly, the multivariate analysis model showed no association between the administration of parecoxib and RFS [hazard ratio (HR), 0.964; 95% confidence interval (CI), 0.599-1.551, P=0.878] or OS (HR, 1.043; 95% CI, 0.621-1.750; P=0.875). In these patients, elevated preoperative neutrophil-lymphocyte ratio (NLR) was demonstrated to be associated with RFS and OS. CONCLUSIONS The present study found that intraoperative parecoxib use was not associated with improved outcome after BCa surgery. Prospective, randomized trials should be performed to further evaluate the results of this study.BACKGROUND Optimal communication and collaboration between inter-disciplinary health care providers is critical to ensuring high quality patient care. We aimed to quantify the impact on physician-nurse collaboration (PNC) of implementing daily goal sheets (DGSs) in emergency settings. METHODS The usage of a DGS was administered in morning rounds in an emergency intensive care unit (ICU) for four consecutive months. A Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSAPNC) form was used before (n=113) and after (n=107) the intervention to evaluate the attitudes of PNCs from the perspective of both physicians and nurses. RESULTS There is a significant positive relation between the attitude to PNC and the participant age, educational background, and professional rank and title before DGS application (P less then 0.01 for each), whereas there was no significant difference observed after the initiation of the DGS. CONCLUSIONS The use of a DGS improves physician-nurse collaborations in emergency care settings.Polystyrene-block-polyethylene oxide (PS-b-PEO) coated surfaces have been explored as cell culture substrates in the past decade. However, their cytocompatibility has not been extensively assessed. In this study, the in vitro cytocompatibility of PS-b-PEO was investigated. Cellular morphology, metabolic activity, and viability were evaluated at 1, 3, and 5 days after cell seeding. Viability was greater than 90% throughout the 5 days culture, with abundant cell spreading evident by the formation of prominent F-actin stress fibres. The cytocompatibility study was complemented by the analysis of adsorption of a range of extracellular matrix proteins on PS-b-PEO thin films by quartz crystal microbalance with dissipation. Protein adsorption tests revealed that there was no significant difference in protein adhesion between surfaces with a PEO domain coverage of ≈28%, compared to the homogeneous polystyrene control. The findings demonstrate that PS-b-PEO thin films are cytocompatible and are a favourable surface coating for cell culture studies.The evaporation of hexane lenses on an ionic liquid (IL) (1-butyl-3-methylimidazolium hexafluorophosphate) surface is studied. The difference between the evaporation processes of the lens on the IL surface and on a distilled water (DW) surface with the same substrate liquid depth (2.6 mm) is primarily analyzed. The variation of the lens contact diameter DC and the deformation of the IL surface were experimentally observed. The results indicated that the spreading stage of a hexane lens was notably shorter in duration on the IL surface than on the DW surface. A hexane lens was pseudopartially wetted on the DW surface, and the plane position of the lens contact diameter remained level with the water surface throughout the evaporation process. In comparison, a hexane lens was partially wetted on the IL surface, and the plane position of the lens contact diameter was lower than the horizontal surface until the lens evaporated completely. The hexane lens evaporation on the IL surface was calculated by using the diffusion-controlled evaporation model under the constant contact angle mode. The calculated results agreed well with the experimental measurements. Finally, the evaporation of hexane lenses on the DW and the IL surfaces was compared through calculations. Although the maximum lens contact diameter on the DW surface was greater, it took a longer time for the lens to evaporate on the DW surface. This is because the more significant bending of the substrate liquid surface accelerated the lens evaporation. The results of this study offer a new approach for controlling droplet evaporation.Gas hydrate formation has several applications in CO2 sequestration, flow assurance, and desalination. Nucleation of hydrates is constrained by very high induction (wait) times, which necessitates the use of complex nucleation promotion techniques to form hydrates. Presently, we report the discovery of a simple, passive nucleation promotion technique, wherein an aluminum surface significantly accelerates nucleation of CO2hydrates. Statistically meaningful measurements of induction times for CO2 hydrate nucleation were undertaken using water droplets as individual microsystems for hydrate formation. The influence of various metal surfaces, droplet size, CO2 dissolution time, and the presence of salts in water on nucleation kinetics was characterized. Interestingly, we observe nucleation initiation only on aluminum surfaces, the influence of which cannot be replicated by salts of aluminum. We discover that the aluminum-water interface is responsible for nucleation promotion. We hypothesize that hydrogen bubbles generated at the aluminum-water interface are responsible for nucleation promotion.Three kinds of perovskite nanoparticles encapsulated with different chain lengths of alkylammonium, (CH3NH3)x(CH3(CH2)3NH3)(1-x)PbBr3 (NP-C4), (CH3NH3)x(CH3(CH2)7NH3)(1-x)PbBr3 (NP-C8), and (CH3NH3)x(CH3(CH2)11NH3)(1-x)PbBr3 (NP-C12), are successfully prepared. X-ray powder diffraction experiments demonstrate that these three nanoparticles are all pure cubic phase. Screening high throughput screening However, the compositions of these three nanoparticles are significantly different, as revealed by steady-state absorption spectra. NP-C4 mainly consists of 2D perovskite with m (number of unit cell layers) = 1 and 3D perovskite. Instead, NP-C8 and NP-C12 are mainly composed of 2D perovskite with m = 3, 4, and 5. Time-resolved fluorescence spectra and femtosecond transient absorption spectra suggest the presence of energy transfer from 2D perovskite to 3D perovskite in these three nanoparticles. More importantly, the energy-transfer rate gradually decreases from NP-C4 to NP-C12. This result suggests that the composition of perovskite nanoparticles and their corresponding photophysical properties can be controlled by the chain length of alkylammonium.
