A Photo-Caged Cross-Linker for Identifying Protein-Protein Interactions.

Cross-linking mass spectrometry (XL-MS) has seen significant improvements which have enhanced its utility for studying protein-protein interactions (PPIs), primarily due to the emergence of novel crosslinkers and the development of streamlined analysis workflows. Nevertheless, poor membrane permeability and side reactions with water limit the extent of productive intracellular crosslinking events that can be achieved with current crosslinkers. To address these problems, we have synthesized a novel crosslinker with o-nitrobenzyl-based photoresponsive groups.

Does a single dose of testosterone increase willingness to compete, confidence, and risk-taking in men? Evidence from two randomised placebo-controlled experiments.

The sex steroid hormone testosterone regulates aggression and display of dominance in non-human animals. According to the Challenge Hypothesis, these effects arise from context-sensitive testosterone increases that facilitate inter-male competitions over resources, status, and mates. A growing body of literature documents similar testosterone effects on behaviors related to competition and risk-taking in humans, though the findings have been mixed.

Categorizing Care Delays and Their Impact on Hospital Length of Stay.

Background And Objective: Unnecessary care delays of hospitalized patients increase the risk of hospital-related complications and drive up health care costs. While health systems focus on reducing the length of stay of hospitalized patients, not many studies looked at specific causes of the care delays that prolong length of stay. In this study, we sought to systematically identify and categorize the various care delays that contribute to prolonged length of stay on a hospital medicine service.

Postoperative protocols for older adults undergoing emergency surgery: a scoping review.

Background: As the population of older adults expands, it is becoming increasingly crucial to develop perioperative protocols to meet their physiologic, functional, and cognitive demands after emergency surgery. We sought to identify protocols that improve the disposition, length of stay, and overall health outcomes of older adults undergoing emergency intracavitary, noncardiac surgery.

Methods: Embase, Cochrane, and MEDLINE databases were searched, and results were deduplicated and uploaded to Covidence.
