A novel predictor for the use of concurrent chemotherapy in early-stage cervical cancer with intermediate-risk factors.

Objective: For early-stage cervical cancer patients experiencing radical surgery, postoperative radiotherapy was recommended for patients with a combination of intermediate-risk factors. However, there was no consensus on whether to administer concurrent chemotherapy. The aim of the study was to confirm the clinical value of the controlling nutritional status (CONUT) score in guiding the use of concurrent chemotherapy during postoperative radiotherapy.

A Novel Risk Factor for Para-Aortic Lymph Node Recurrence After Definite Pelvic Radiotherapy in Stage IIIB Cervical Cancer.

Studies determining which patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIB disease benefit from prophylactic extended-field irradiation (EFRT), which can reduce para-aortic lymph node (PALN) failure rates, are limited. The study was designed to evaluate the value of the controlling nutritional status (CONUT) score as a risk factor for predicting PALN recurrence and identifying potential indications of prophylactic EFRT. From 2010 to 2015, a retrospective review was conducted among patients with FIGO stage IIIB cervical cancer who were treated with definitive pelvic radiotherapy or concurrent chemoradiotherapy.

The effectiveness of consolidation chemotherapy in high-risk early-stage cervical cancer patients following concurrent chemoradiation after radical surgery.

Objective: Studies determining which early-stage cervical cancer patients with high-risk factors benefit from consolidation chemotherapy after postoperative concurrent chemoradiotherapy (CCRT) are limited and inconsistent. The aim of this study was to evaluate the value of consolidation chemotherapy in early-stage cervical cancer.

Methods: From 2010 to 2019, a retrospective review was conducted among high-risk early-stage cervical cancer patients who were treated with postoperative CCRT or consolidation chemotherapy after postoperative CCRT.

Absorption enhancement in visible range from Fano resonant silicon nanoparticle arrays embedded in single crystal Mg:Er:LiNbOsynthesized by direct ion implantation.

Fano resonant Si nanoparticles (NPs) are synthesized in single-crystal Mg:Er:LiNbOusing ion implantation and subsequent thermal annealing. The structural and optical properties of the Si NPs embedded in the crystal have been investigated. Spherical particles with radius of about 60 nm are observed by cross-sectional transmission electron microscope, while ion beam analysis are used to characterize the NPs formation process.

Study on the feasibility of quality improvement for automatic plans based on rapid plan model.

Objective: To study whether an interactive improved internal feedback system with the model can be established, we compared the plans generated by two automatic planning models.

Methods: Seventy cases of pelvic patients were selected. Intensity-modulated radiation therapy (IMRT) plans (P0) generated by the clinical model (M0) were imported into the Rapid plan model to establish a dose-volume histogram.

Investigation of optical absorption enhancement of plasmonic configuration by graphene on LiNbO-SiOstructure.

A novel plasmonic structure is demonstrated by combining graphene with a planar LiNbOthin layer, which is simple and easy to fabricate compared to the complex design of general graphene surface plasmons devices. Graphene from the chemical vapor deposition is investigated and characterized to be a continuous and uniform monolayer or fewlayer. LiNbOcapped by graphene layer show an extraordinary absorption enhancement in an attenuated total reflection (ATR) measurement at a wide bandwidth of 500-4000 cm, which can be explained by resonance absorption resulting from the coupling of graphene surface plasmons with optical modes of LiNbO-SiOFabry-Perot cavity and LiNbOplanar waveguide.

Investigation of novel optical and waveguide characteristics for an air-graphene-LiNbOsystem.

The optical characteristics of a planar thin film waveguide system composed of air-graphene-LiNbOhave been investigated. Monolayer or bilayer graphene of high quality are characterized by Raman spectroscopy, scanning electron microscopy and atomic force microscopy. The refractivity and reflectivity of the air-graphene-LiNbOsystem are measured experimentally and compared with those of a LiNbOwaveguide by the prism coupling method.

Enhancement of near-infrared photoluminescence in Mg:Er:LiNbO containing Au nanoparticles synthesized by direct ion implantation.

Embedded gold (Au) nanoparticles (NPs) are formed in Mg:Er:LiNbO single crystals by Au ion implantation and subsequent thermal annealing. Absorption of the Mg:Er:LiNbO crystals with Au NPs is found to be enhanced significantly in the visible light wavelength band owing to the localized surface plasmon resonance (LSPR) effect. The calculated LSPR effect by Mie theory shows good agreement with the absorption spectra.

Dosimetric study of three-dimensional static and dynamic SBRT radiotherapy for hepatocellular carcinoma based on 4DCT image deformable registration.

The purpose of this work was to determine the actual dose received by normal tissues during four-dimensional radiation therapy (4DRT) composed of ten phases of four-dimensional computer tomography (4DCT) images. The analysis was performed by tracking the hepatocellular carcinoma SBRT. Data were acquired from the tracking of each phase with the beam aperture for 28 hepatocellular carcinoma patients, and the data were used to generate a cumulative plan, which was compared to a three-dimensional (3D) plan formed from a merged target volume based on 4DCT images in a radiation treatment planning system (TPS).

Fabrication and analysis of single-crystal KTiOPO₄ films with thicknesses in the micrometer range.

Single-crystal potassium titanyl phosphate (KTiOPO4, KTP) films with thicknesses less than 5 μm are obtained by using helium (He) implantation combined with ion-beam-enhanced etching. A heavily damaged layer created by a 4×10(16)  cm(-2) fluence of 2 MeV He implantation is removed by means of wet chemical etching in hydrofluoric acid (HF). Thus, free-standing films of KTP with thicknesses in the range of 3-5 μm are obtained.
