Abstract A series of uniform single-phase spherical BaWO₄: Dy³⁺, Tm³⁺, Eu³⁺ phosphors were prepared via a microwave hydrothermal method by using trisodium citrate dehydrate as surfactant. The phase structure, morphology and photoluminescence properties were measured by powder X-ray diffraction, scanning electron microscope and fluorescence spectrometer, respectively. The results show that uniform spherical microcrystals with diameters in the range of 2–4 μm are obtained. And the phase and morphology of samples are not significantly changed by doping rare earth (RE³⁺) ions. Under the excitation wavelength of 356 and 365 nm, the samples BaWO₄: 0.03Dy³⁺, yTm³⁺ can emit cold white light. In order… More >

Abstract Drug discovery research to fight lung cancer is incessantly challenged by drug resistance. In this study, we used drug-resistant lung cancer stem like cells (A549-CS) to compare the efficacy of standard drugs like cisplatin (DDP) and gemcitabine (GEM) with a novel arylidene derivative IOX-101. A549-CS was derived from regular A549 cells by growing in special media. Resistance proteins were detected using Western blotting. Cell proliferations were assessed by MTT assay. Cytokine release was enumerated using enzyme-linked immunosorbent assay. The effect of drugs on apoptosis and cell cycle was studied with flow cytometry protocols. Apoptosis-related proteins,… More >

Abstract Introduction: The prostate-specific antigen (PSA) screening test is controversial and can result in both over-diagnosis and over-treatment. Recently, the Canadian Task Force on Preventive Health Care (CTFPHC) has recommended against routine screening for prostate cancer. We sought to determine how the CTFPHC has impacted the practice patterns among family physicians in the North Simcoe Muskoka (NSM) Local Health Integration Network (LHIN).
Materials and methods: We surveyed all 439 family physicians within the NSM LHIN as well as 21 residents of the Family Medical Teaching Unit. Surveys were distributed by either mail or fax. Questions covered three sections:… More >

Abstract In this paper, the choice and parametrisation of finite deformation polyconvex isotropic hyperelastic models to describe the behaviour of a class of defect-free monocrystalline metal materials at the molecular level is examined. The article discusses some physical, mathematical and numerical demands which in our opinion should be fulfilled by elasticity models to be useful. A set of molecular numerical tests for aluminium and tungsten providing data for the fitting of a hyperelastic model was performed, and an algorithm for parametrisation is discussed. The proposed models with optimised parameters are superior to those used in non-linear More >

Abstract During the last decades, multigrid methods have been extensively used in order to solve large scale linear systems derived from the discretization of partial differential equations using the finite difference method. Approximate Inverses in conjunction with Richardon’s iterative method could be used as smoothers in the multigrid method. Thus, a new class of smoothers based on approximate inverses could be derived. Effectiveness of explicit approximate inverses relies in the fact that they are close approximants to the inverse of the coefficient matrix and are fast to compute in parallel. Furthermore, the class of finite difference More >

Abstract Introduction: Level 1 evidence demonstrates the benefit of postoperative radiotherapy (PORT) for pT3 disease and positive margins. The role of androgen deprivation therapy (ADT) after PORT remains to be defined from results of ongoing randomized trials. This study was undertaken to determine the factors influencing the current use of ADT after PORT amongst Canadian radiation oncologists.
Methods: An institutional survey was emailed to the Genito-urinary Radiation Oncologists Group of Canada (GUROC), designed to assess the likelihood of prescribing ADT in early and delayed PORT scenarios with variations in disease prognosticators. Analysis used descriptive statistics.
Results: Majority (94%) do… More >
