Places of worship serve as a venue for both mass and routine gathering around the world, and therefore are associated with risk of large-scale SARS-CoV-2 transmission. However, such routine gatherings also offer an opportunity to distribute self-tests to members of the community to potentially help mitigate transmission and reduce broader community spread of SARS-CoV-2. Over the past four years, self-testing strategies have been an impactful tool for countries' response to the COVID-19 pandemic, especially early on to mitigate the spread when vaccination and treatment options were limited.

Gluten proteins are storage proteins in wheat that exhibit a certain resistance to gastrointestinal digestion. To explore solutions to cope with accidental ingestion of gluten in individuals suffering from gluten-related disorders, it is essential to monitor the fate of gluten peptides in biological samples, , gastrointestinal juices, blood plasma or urine. In this work, we aimed at developing a mass spectrometry (MS)-based method for measuring gluten peptides in human duodenal fluids.

Article Synopsis
  • The study investigates how specific material properties (phosphate content and stiffness) of a collagen scaffold affect the expression of osteoprotegerin (OPG), an important protein for regulating bone resorption, in human mesenchymal stem cells (hMSCs).
  • The findings reveal that OPG expression is dependent on the phosphate content through a sodium phosphate transporter and is influenced by the mechanical properties of the material, with softer materials leading to higher OPG production.
  • The research also shows that the downregulation of β-catenin, a key signaling molecule, can enhance OPG expression, suggesting a potential strategy for developing materials that promote bone protection while separating it from bone formation processes.
