OBJECTIVE To identify the correlation between magnetic resonance manifestation and survival of patients with glioblastoma multiforme (GBM). METHODS The magnetic resonance imaging (MRI) images of 30 glioblastoma patients were collected. Imaging features including degrees of contrasted area, edema surrounding the tumor, and intensity in T2-weighted imaging were selected to determine their corre...

This paper demonstrates that the standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a tiny amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. The analysis is centered around a specific measure of wage dispersion— the ratio between the average wage and the lowes...

Being outdoors in a natural environment is thought to be restorative and relaxing (Kaplan & Kaplan, 1989). For people with dementia, nature and outdoor spaces (‘ingericht groen’) can provide a stimulating environment with exposure to light and sensory experiences (Burns et al. 2002; GuissetMartinez et al., 2013) as well as engagement in pleasant activities (Mac-Donald, 2002). It is reported tha...

In some long term studies, a series of dependent and possibly censored failure times may be observed. Suppose that the failure times have a common marginal distribution function, and inferences about it are of our interest. The main result of this paper is that of providing, under certain regularity conditions, the Kaplan-Meier estimator can be expressed as the mean of random variables, with a ...

BACKGROUND The diagnosis of pseudo-responses after bevacizumab treatment is difficult. Because diffusion-weighted imaging (DWI) is associated with cell density, it may facilitate the differentiation between true- and pseudo-responses. Furthermore, as high b-value DWI is even more sensitive to diffusion, it has been reported to be diagnostically useful in various clinical settings. MATERIALS A...

Objective: To correlate non-restricted diffusion magnetic resonance imaging (MRI) patterns of hepatocellular carcinoma (HCC), with histopathology and clinical outcome.Material Methods: We retrospectively evaluated pre-treatment MRIs showing HCC lesions (≥1-centimeter), excluding poor quality/non-available weighted (DWI). Three radiologists 37 in 27 patients, for: T1-weighted (T1W)/T2-weighted (...
