Posttraumatic stress and posttraumatic growth among female and male veterans: The contribution of romantic relationship and friendship functioning.

Posttraumatic growth (PTG) is characterized as the experience of positive psychological change following exposure to traumatic stress. However, studies examining the association between posttraumatic stress disorder (PTSD) symptoms and PTG have demonstrated mixed results. Further, although higher levels of social support have been shown to predict higher ratings of PTG, there are limited longitudinal findings regarding how interpersonal functioning may affect the association between PTSD symptoms and PTG.

Hypointense Findings on Hepatobiliary Phase MR Images.

Hepatobiliary (HB) contrast agents are increasingly valuable diagnostic tools in MRI, offering a wider range of applications as their clinical use expands. Normal hepatocytes take up HB contrast agents, which are subsequently excreted in bile. This property creates a distinct HB phase providing valuable insights into liver function and biliary anatomy.

Understanding the regulatory-procurement interface for medicines in Africa via publicly available information on standards, implementation, and enforcement in five countries.

Background: Substandard and falsified medicines in Africa are a major public health concern. Access to quality medical products in African countries is governed in large part by two major entities at the national level: the regulatory authority and the procurement agency. The importance of national regulators in ensuring quality medical products is well known.

Stereoselective amino alcohol synthesis via chemoselective electrocatalytic radical cross-couplings.

Amino alcohols are vital in natural products, pharmaceuticals and agrochemicals, and as key building blocks for various applications. Traditional synthesis methods often rely on polar bond retrosynthetic analysis, requiring extensive protecting group manipulations that complicate direct access. Here we show a streamlined approach using a serine-derived chiral carboxylic acid in stereoselective electrocatalytic decarboxylative transformations, enabling efficient access to enantiopure amino alcohols.

Virus-modified paraspeckle-like condensates are hubs for viral RNA processing and their formation drives genomic instability.

The nucleus is a highly organised yet dynamic environment containing distinct membraneless nuclear bodies. This spatial separation enables a subset of components to be concentrated within biomolecular condensates, allowing efficient and discrete processes to occur which regulate cellular function. One such nuclear body, paraspeckles, are comprised of multiple paraspeckle proteins (PSPs) built around the architectural RNA, NEAT1_2.
