Single-cell methods to assess DNA methylation have not achieved the same level of cell throughput per experiment compared to other modalities, with large-scale datasets requiring extensive automation, time, and other resources. Here, we describe sciMETv3, a combinatorial indexing-based technique that enables atlas-scale libraries to be produced in a single experiment. To reduce the sequencing burden, we demonstrate the compatibility of sciMETv3 with capture techniques to enrich regulatory regions, as well as the ability to leverage enzymatic conversion, which can yield higher library diversity.

Background: Patients undergoing cardiac surgery are identified as high risk for infection, including MRSA. An outbreak of MRSA was identified when two patients experienced MRSA infection concurrently in a cardiothoracic high dependency unit with uncommon detection of MRSA previously and an established screening programme.

Methods: An outbreak control team was convened and interventions applied including refresher training in hand and environmental hygiene, review of practice with regard to aseptic access of medical devices and consideration of antibiotic use in the unit.

Article Synopsis
  • This study examined how playing multiple seasons of rugby affects serum S100B levels in male professional players and the acute impact of concussion on these levels.
  • Researchers collected blood samples during different seasons of play and after concussions to measure S100B concentrations using an ELISA assay.
  • The results showed that while S100B levels remained stable across seasons, they significantly increased immediately after concussions, but returned to pre-season levels by the end of the season, suggesting S100B could be a valuable tool in managing sports-related concussions.

The impact of the degradation of monoethanolamine (MEA) on the physicochemical properties of the solvent is experimentally characterized. Based on the identification of three main degradation products of MEA: oxazolidine-2-one (OZD), N-(2-hydroxyethyl)ethylenediamine (HEEDA), and 1-(2-hydroxyethyl)-2-imidazolidinone (HEIA), new measurements for the density, surface tension, and viscosity of partially carbonated solutions containing water, MEA and those products were conducted at different MEA/degradation product molar ratios. The experiments covered a temperature range from 298.

We report an outbreak of PVL-producing MRSA in the Irish National Burns Unit in 2022 involving seven patients, two staff members and two positive environmental samples. This outbreak was successfully controlled using a range of measures including staff screening, environmental screening and enhanced cleaning. The use of real time whole genome sequencing (WGS) allowed for rapid identification of relatedness and for a rapid outbreak response.
