Article Synopsis
  • - Recent research suggests that supermassive black holes may suppress star formation in massive galaxies by driving large outflows, but concrete evidence has been scarce, especially in the young universe where star formation happens quickly.
  • - Although outflows of ionized gas are commonly observed, they don’t contain enough mass to hinder star formation, with more effective gas ejection expected in neutral and molecular phases that are only seen in more extreme conditions like starbursts and quasars.
  • - New spectroscopy from the JWST reveals a massive galaxy at a redshift of 2.445 undergoing rapid star formation suppression, detecting a significant outflow of neutral gas that should effectively halt star creation, indicating that supermassive black holes can rapidly quench

The genital mycoplasmas are a unique group of inherently antibiotic-resistant sexually transmitted bacteria, often associated with non-gonococcal urethritis and bacterial vaginosis. The MYCO WELL D-ONE is a culture-based assay that aims to detect these organisms whilst concurrently screening them for antibiotic resistance. Urine and/or swabs from 856 informed and consented participants attending Welsh sexual health clinics were subjected to MYCO WELL D-ONE analysis, alongside qPCR and culture titration methodologies to determine sensitivity, specificity, PPV, NPV and accuracy.

Objectives: Mycoplasma genitalium (MG) is a common cause of sexually transmitted infection, however no prevalence data is available for Wales. MG was detected by qPCR (quantitative) as well as two separate SpeeDx commercial assays, and related to clinical symptoms, age, gender and sample type.

Methods: Cervical swabs, urethral swabs and/or urine were collected from 1000 patients at walk-in sexual health clinics at 3 Welsh health centres from October 2017-October 2018.

Articular cartilage is composed of chondrons within a territorial matrix surrounded by a highly organized extracellular matrix comprising collagen II fibrils, proteoglycans, glycosaminoglycans, and non-collagenous proteins. Damaged articular cartilage has a limited potential for healing and untreated defects often progress to osteoarthritis. High hopes have been pinned on regenerative medicine strategies to meet the challenge of preventing progress to late osteoarthritis.
