Objective: Adhesions between the uterus, bladder and anterior abdominal wall are associated with clinical sequelae, including chronic pelvic pain and dyspareunia, and can also yield complications during surgery. The transvaginal sonographic (TVS) sliding bladder sign is a minimally invasive diagnostic tool to evaluate the presence of vesicouterine adhesions. This study aimed to determine the predictive value and intra- and interobserver variation of the TVS sliding bladder sign in the assessment of vesicouterine adhesions.

Article Synopsis
  • - This study investigates how mammals adapt their respiratory complexes in brown fat when exposed to cold temperatures, focusing on the role of brown fat in thermogenesis.
  • - Researchers utilized cryoelectron microscopy and combined it with physiological studies to uncover a specific cold-induced conformation of respiratory supercomplexes in mice, enhancing electron transfer and catalytic activity.
  • - Findings from simulations and biochemical analyses demonstrated the interplay between lipid-protein arrangements and the stabilization of these complexes, shedding light on the structural and energetic mechanisms that boost respiratory capacity in brown fat during cold exposure.

Aim: This qualitative focus group study aims to asses cerclage-related symptoms, the impact of a cerclage on daily functioning and patient perspectives of their healthcare experience. This study extends beyond the current focus on surgical and obstetric outcomes of a cerclage, thereby contributing to a more comprehensive understanding of the challenges faced by individuals in the context of extreme preterm birth and fetal loss and the impact of a cerclage on multiple facets in life.

Methods: Participants were recruited from the Amsterdam University Medical Center, Amsterdam, the Netherlands or via the website of a Dutch patient organization for (extreme) preterm birth.

Ergothioneine (EGT) is a diet-derived, atypical amino acid that accumulates to high levels in human tissues. Reduced EGT levels have been linked to age-related disorders, including neurodegenerative and cardiovascular diseases, while EGT supplementation is protective in a broad range of disease and aging models in mice. Despite these promising data, the direct and physiologically relevant molecular target of EGT has remained elusive.

Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in x-ray absorption, which we interpret as quasi-periodic outflows (QPOuts) from a previously low-luminosity active galactic nucleus after an outburst, likely caused by a stellar tidal disruption. We rule out several models based on observed properties and instead show using general relativistic magnetohydrodynamic simulations that QPOuts, separated by roughly 8.
