Gold nanoparticles (GNPs) were modified with glutathione (GSH) to form GSH-capped GNPs, which have carboxyl groups on the surface of these nanoparticles. Then folic acid (FA) was conjugated with GNPs through the reaction between amino group of FA and carboxyl group of GSH. These folic acid-conjugated nanoparticles (FA-GSH-GNPs) were stable in aqueous(More)
For single-fraction stereotactic radiosurgery (SRS) using linac in brain metastases, more accurate treatment delivery with higher tumor absorbed doses and lower absorbed doses to normal tissues remains an enormous challenge. The purpose of this study was to investigate the dosimetric superiority in flattening filter free beams (FFF) for volumetric modulated(More)
OBJECTIVES To compare the target volume coverage and doses to organs at risks (OARs) using three techniques that simultaneous integrated boost (SIB) in whole-breast irradiation (WBI) after breast-conserving surgery, including intensity-modulated radiation therapy (IMRT), IMRT plus an electron boost (IMRT-EB), and volumetric-modulated arc therapy (VMAT).

Biodegradable poly(lactic-co-glycolic acid) (PLGA)/carboxyl-functionalized multi-walled carbon nanotube (c-MWCNT) nanocomposites were successfully prepared via solvent casting technique. Rat bone marrow-derived mesenchymal stem cells (MSCs) were employed to assess the biocompatibility of the nanocomposites in vitro. Scanning electron microscopy (SEM)(More)
PURPOSE Flattening filter free (FFF) beams show the potential for a higher dose rate and lower peripheral dose. We investigated the planning study of FFF beams with their role for volumetric modulated arc therapy (VMAT) in squamous cell carcinoma of the scalp. METHODS AND MATERIALS One patient with squamous cell carcinoma which had involvement of entire(More)
Conventional volumetric modulated arc therapy (C-VMAT) for breast cancer after radical mastectomy had its limitation that resulted in larger volumes of normal tissue receiving low doses. We explored whether there was a way to deal with this disadvantage and determined the potential benefit of flattening filter-free (FFF) beams.Twenty patients with breast(More)
The instability of few-layer black phosphorus (FL-BP) hampers its further applications. Here, it can be demonstrated that the instability of FL-BP can also be the advantage for application in biosensor. First, gold nanoparticle/FL-BP (BP-Au) hybrid is facilely synthesized by mixing Au precursor with FL-BP. BP-Au shows outstanding catalytic activity (K =(More)
