Composites made of flame-sprayed bioactive glass 45S5 and polymers: bioactivity and immediate sealing properties [PDF]

, 2010
AIM: To engineer systems using polyisoprene (PI) or polycaprolactone (PCL) and nanometric bioactive glass 45S5 (BG) that could create a hydroxyapatite interface and thus ultimately make the use of an endodontic sealer unnecessary.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Basroparib inhibits YAP‐driven cancers by stabilizing angiomotin

Molecular Oncology, EarlyView.
Basroparib, a selective tankyrase inhibitor, suppresses Wnt signaling and attenuates YAP‐driven oncogenic programs by stabilizing angiomotin. It promotes AMOT–YAP complex formation, enforces cytoplasmic YAP sequestration, inhibits YAP/TEAD transcription, and sensitizes YAP‐active cancers, including KRAS‐mutant colorectal cancer, to MEK inhibition.

Antimicrobial Efficacy of Medicated Root Canal Filling Materials

Journal of Endodontics, 2006
Bacteria remaining within the root canal system are a significant factor in endodontic failures. The aim of this in vitro study was to evaluate the antimicrobial efficacy of commercially available gutta-percha formulations against common endodontic pathogens. Standard, tetracycline, or iodoform (also called medicated gutta-percha; MGP) containing gutta-
