    • The effect of smear layer removal on E. faecalis leakage and bond strength of four resin-based root canal sealers 

      Andriukaitiene, Laura; Song, Xiaobo; Yang, Nannan; Lippo V. J., Lassila; K. Vallittu, Pekka; Kerosuo, Eero (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-13)
      <p><i>Background</i>: The aim of the study was to assess bacterial sealability and bonding ability of methacrylate-based Resilon (RS, SybronEndo), Endo Rez (ER, Ultradent Products Inc), and epoxy-based AH Plus (AH, Dentsply/DeTrey), MTA Fill Apex (MTAF, Angelus Soluções Odontológicas) root canal sealers, and the effect of the smear layer removal on the sealability.</p> <p><i>Methods</i>: One ...

    • Irradiated tumor fibroblasts avoid immune recognition and retain immunosuppressive functions over natural killer cells 

      Yang, Nannan; Lode, Kristin; Berzaghi, Rodrigo; Islam, Md Ashraful; Martinez, Inigo Zubiavrre; Hellevik, Turid (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-22)
      Recent studies have demonstrated that radiotherapy is able to induce anti-tumor immune responses in addition to mediating direct cytotoxic effects. Cancer-associated fibroblasts (CAFs) are central constituents of the tumor stroma and participate actively in tumor immunoregulation. However, the capacity of CAFs to influence immune responses in the context of radiotherapy is still poorly understood. ...

    • Radiation-induced effects on TGF-beta and PDGF receptor signaling in cancer-associated fibroblasts 

      Yang, Nannan; Hellevik, Turid; Berzaghi, Rodrigo; Martinez, Inigo Zubiavrre (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-15)
      Background - Cancer-associated fibroblasts (CAFs) consist of heterogeneous connective tissue cells and are often constituting the most abundant cell type in the tumor stroma. Radiation effects on tumor stromal components like CAFs in the context of radiation treatment is not well-described.<p> <p>Aim - This study explores potential changes induced by ionizing radiation (IR) on platelet-derived ...
