Removable poly(methyl methacrylate) (PMMA) dentures are prone to bacterial adherence and plaque formation. Denture plaque-associated infection is a source of serious dental and medical complications in the elderly. This paper introduces a novel protocol to treat PMMA dentures with 2-methacryloyloxyethyl phosphorylcholine polymer, poly(MPC-co-BMA-co-MPAz), to suppress plaque deposition on PMMA dentures.
An in vitro method for establishing dual resistance to an EGFR-TKI and a MET-TKI in cancer cells is described. This method is useful for developing treatments for patients with EGFR-mutations, who exhibit disease progression despite EGFR-TKI treatment with MET-amplification. It can also be modified for inhibitors targeting other molecules.
A method for establishing afatinib-resistance cell lines from lung adenocarcinoma PC-9 cells was developed, and resistant cells were characterized. The resistant cells can be used to investigate epidermal growth factor receptor tyrosine kinase inhibitor-resistance mechanisms, applicable for patients with non-small cell lung cancer.
