Purpose: Dephasing gradients can be introduced within a variety of gradient-echo pulse sequences to delineate local susceptibility changes ("White-Marker" phenomenon), e.g., for the visualization of metallic interventional devices which are otherwise difficult to display.

Purpose: To propose a two-step, nonlocal principal component analysis (PCA) method and demonstrate its utility for denoising complex diffusion MR images with a few diffusion directions.
Methods: A two-step denoising pipeline was implemented to ensure accurate patch selection even with high noise levels and was coupled with data preprocessing for g-factor normalization and phase stabilization before data denoising with a nonlocal PCA algorithm. At the heart of our proposed pipeline was the use of a data-driven optimal shrinkage algorithm to manipulate the singular values in a way that would optimally estimate the noise-free signal.

Background: Media portrayals inform understandings of mental illness; yet little research has investigated representations of characters with psychosis in fictional television programming.
Aims: This study examined the valence and trends regarding representations of people with psychosis in popular fictional television programing in the United States, one of the most influential markets in the world.
Methods: A content analysis was conducted of the 50 most-watched American primetime fictional television shows from 2011 to 2021.

In order to relate nanoparticle properties to function, fast and detailed particle characterization is needed. The ability to characterize nanoparticle samples using optical microscopy techniques has drastically improved over the past few decades; consequently, there are now numerous microscopy methods available for detailed characterization of particles with nanometric size. However, there is currently no "one size fits all" solution to the problem of nanoparticle characterization.

Background And Aim: Linaclotide is effective in relieving constipation-predominant irritable bowel syndrome symptoms. However, few studies focus on the efficacy of linaclotide for overlapping symptoms of functional dyspepsia among irritable bowel syndrome patients. This study aimed to assess the efficacy of linaclotide compared with lactulose in patients with functional dyspepsia and constipation-predominant irritable bowel syndrome overlap.
