Radiofrequency ablation (RFA) is currently one of the most effective methods for minimally invasive treatment of hepatic tumors. Planning the probe placements is an essential and challenging step in RFA treatment. To completely destroy the tumor with minimum amount of affected native tissue, a new RFA planning system is proposed in this paper. In the proposed planning system, the minimum number of ablations and a conical insertion region for each ablation session are determined automatically. Based on the geometric character of the tumor, a novel clustering algorithm is developed to allow a better layout of the overlapping...

Publication date: 15 May 2018 Source:Journal of Alloys and Compounds, Volume 745 Author(s): Yuhao Xu, Qing Zhou, Yin Du, Yue Ren, Haimin Zhai, Qiang Li, Jialin Chen, Haifeng Wang The design of highly processable metallic glass matrix composites (MGMCs) is driven by optimizing the mechanical properties such as strength and ductility. In this work, by using X-ray diffraction (XRD), scan electron microscopy (SEM), energy dispersive spectroscope (EDS), transmission electron microscopy (TEM) and compressive testing, we reported that the microstructure and mechanical properties of Ti-based MGMCs can be tuned by a minor addition...

AbstractPurposeWe investigated prospectively whether18F-2-fluoro-2-deoxyglucose positron emission tomography/computed tomography (FDG PET/CT) can predict the overall survival (OS) of patients with advanced renal cell carcinoma (RCC) previously treated by molecular targeted therapies.MethodsBetween 2009 and 2016, 81 patients who had received single molecular targeted therapies (43 sorafenib, 27 sunitinib, 8 temsirolimus and others) and were scheduled for second line molecular targeted therapies for advanced RCC were enrolled in this prospective study. FDG PET/CT was performed after first line molecular targeted therapies, t...

Andraca-Adame, J.D. Pérez-Martínez Candelilla wax (CW) organogels were produced with and without emulsifiers in high oleic safflower oil. The organogel’s crystal structure was imaged at the micro and nanoscale using polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The PLM micrographs of the CW organogels dis...

Russkikh, Alexander V. Linovsky The paper provides an analysis of the influence of the Rehbinder effect, electrical erosion and wire tension on breakages during wire electrical discharge machining (EDM) of steel 36CrNiMo4 (the analogue of AISI 9840) by the SODICK VZ300L machi. A classification of wire breakages (explicit and implicit) is proposed and the reasons for both breakage types are considered. The methods of optical micros...

Objectives Despite an asbestos ban in the European Union, exposure to asbestos still represents an occupational risk. Biomarkers of DNA damage and genomic instability in groups exposed to asbestos may contribute to the identification of subgroups/subjects at higher risk. Methods A cross-sectional study was conducted on 468 male individuals (80 working in occupational settings with potential exposure to asbestos fibers, 202 retired workers with past exposure, and 186 non-exposed controls) to compare genomic instability, cell proliferation and differentiation leve l using the non-invasive micronucleus buccal cytome assay. ...

In this work, it is proposed a new strategy to improve the dispersion of inorganic fillers in polymeric matrices by producing surface carbon nanostructures. Clay/carbon nanofibers particles were prepared and used as fillers to improve the mechanical and thermal properties of ultra-high molecular weight polyethylene (UHMWPE). Thermogravimetry (TG), differential scanning calorimetry (DSC), elemental analyses, Raman, X-ray diffraction (XRD) and scanning electron microscopy (SEM) showed that chemical vapor deposition (CVD) with ethanol at different temperatures, i.e. 700, 800 and 900 °C with and without Fe catalyst, can be...
