The aim of this study was to evaluate the potential for using the natural frequency (NF) as a parameter to detect vertical bone loss at the furcation of human molars as well as to assess the role that the surrounding bone plays in maintaining molar stability. A three-dimensional finite element model of the human maxillary molar was built. The NF values of(More)
Etanidazole, a hypoxic radiosensitizer, has potential applications in radiotherapy. Due to its high solubility in water, common methods to encapsulate etanidazole into microspheres are not feasible. In this study, a spray-drying technique was employed to encapsulate etanidazole into the biodegradable polymer, PLGA65:35. Different fabrication conditions,(More)
OBJECTIVE Therapeutic resistance has been a great obstacle for successful treatment of breast cancer. Our study aimed to explore the role of microRNA-760 (miR-760) in chemoresistant breast cancer cells. MATERIALS AND METHODS Real-time PCR was performed to measure the mRNA expression of miR-760 and Nanog. Western blot was used to determine the protein(More)
The performances of organic semiconductor devices are crucially linked with their stability at the ambient atmosphere. The evolution of electronic structures of 20 nm thick rubrene films exposed to ambient environment with time has been studied by UV and X-ray photoemission spectroscopy (UPS and XPS), near edge X-ray absorption fine structure (NEXAFS)(More)
OBJECTIVE To discuss the relationship between the internal oxidation-reduction system and fetal distress in pregnant patients with intrahepatic cholestasis in order to provide a new basis for clinical treatment and research. PATIENTS AND METHODS From March 2012 to March 2015, eighty patients with intrahepatic cholestasis of pregnancy (ICP) were selected(More)
