Multilayer graphene sheets (MLGSs) are promising nano-reinforcements that can effectively enhance the properties of polymer matrices. Despite many studies on MLGSs-reinforced polymer nanocomposites, the effect of wrinkles formed in MLGSs on the reinforcement effect and the viscoelastic properties of polymer nanocomposites has remained unknown. In this study, building upon previously developed coarse-grained models of MLGSs and poly(methyl methacrylate) coupled with molecular dynamics simulations, we have systematically investigated nanoco

Adenoid cystic carcinoma (ACC) is a rare tumor developed in minor salivary glands, the palate being the most common site. Here, we report a case of a 58-year-old man with a 3-year-growing swelling in the right palate diagnosed with high grade transformation adenoid cystic carcinoma. The exam revealed a 4 cm large mass. A tumor resection with a radical neck dissection was performed. High grade transformation in adenoid cystic carcinoma is recently described by Cheuk et al. in 1999. This transformation has more aggressive behavior
