Desktop 3D printers in the workplace: use, emissions, controls, and health.

Desktop three-dimensional (3D) printers are used in businesses, schools, and colleges, and are generally of an unenclosed design which may give rise to injuries or inhalation exposure to emissions of small particles (<1 µm) and volatile organic compounds (VOCs). The aim of this work was to explore the health risks related to the use of desktop 3D printers in workplaces in the United Kingdom. A digital survey on the use of desktop 3D printers was completed voluntarily and anonymously between February and June 2023, receiving 146 responses.

Neighborhood disorder and social cohesion: A longitudinal investigation of links with maternal cardiometabolic risk one year postpartum.

Objective: Neighborhood characteristics can influence cardiometabolic health, including during the perinatal period. However, maternal health research has largely examined the influence of objective neighborhood measures, limiting insights into psychological and social processes. We examined associations of perceived neighborhood disorder and social cohesion with maternal cardiometabolic risk 1 year postpartum and explored potential pathways of psychological distress and physical activity.

Lateral epiglottic collapse in obstructive sleep apnea is associated with laterally directed pharyngeal collapse.

Study Objectives: Epiglottic collapse can obstruct the airway in obstructive sleep apnea (OSA) patients in an anteroposterior (E-ap) or lateral direction (E-lat). The present study investigates the concept that lateral or concentric pharyngeal collapse patterns may remodel the epiglottis and predispose it to lateral collapse. To do so, we hypothesized that the presence of-any form of laterally directed pharyngeal collapse, e.

Identifying the minimal sets of distance restraints for FRET-assisted protein structural modeling.

Proteins naturally occur in crowded cellular environments and interact with other proteins, nucleic acids, and organelles. Since most previous experimental protein structure determination techniques require that proteins occur in idealized, non-physiological environments, the effects of realistic cellular environments on protein structure are largely unexplored. Recently, Förster resonance energy transfer (FRET) has been shown to be an effective experimental method for investigating protein structure in vivo.
