    • Bacterial leakage in ex vivo teeth after apicoectomy using two tricalsium silicate-based cements as root-end filling materials 

      Tinnan, Tamar; Nergård, Siril; Ellingsen, Siri (Master thesis; Mastergradsoppgave, 2014)
      Abstract Background The main cause of pulpal and periradicular pathosis are microorganisms and their by products in the root canal system. These have to be eliminated to promote healing. Because it´s impossible to achieve a bacteria-free root canal an additional goal of endodontic therapy is to seal the root canal system from the outside environment. Today the standard method for filling the ...

    • The bacterial magnesium transporter MgtA reveals highly selective interaction with specific cardiolipin species 

      Weikum, Julia; van Dyck, Jeroen F.; Subramani, Saranya; Klebl, David P.; Storflor, Merete; Muench, Stephen P.; Abel, Sören; Sobott, Frank; Morth, Jens Preben (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-23)
      The bacterial magnesium transporter A (MgtA) is a specialized P-type ATPase important for Mg<sup>2+</sup> import into the cytoplasm; disrupted magnesium homeostasis is linked to intrinsic ribosome instability and antibacterial resistance in Salmonella strains. Here, we show that MgtA has functional specificity for cardiolipin 18:1. Still, it reaches maximum activity only in combination with ...
