57 × 105 g/m3 during a 5 min adsorption process. The high-performance photothermal self-heated superoleophilic CuO@CuS/PDMS NWAs/CF has a promise of promoting the practical applications of the sorbents in the clean up of viscous crude oil spills.The field of terminal proteomics is limited in that it is optimized for large-scale analysis via multistep processes involving liquid chromatography. Here, we present an integrated N-terminal peptide enrichment method (iNrich) that can handle as little as 25 μg of cell lysate via a single-stage encapsulated solid-phase extraction column. iNrich enables simple, rapid, and reproducible sample processing, treatment of a wide range of protein amounts (25 μg ∼ 1 mg), multiplexed parallel sample preparation, and in-stage sample prefractionation using a mixed-anion-exchange filter. We identified ∼5000 N-terminal peptides (Nt-peptides) from only 100 μg of human cell lysate including Nt-formyl peptides. Multiplexed sample preparation facilitated quantitative and robust enrichment of N-terminome with dozens of samples simultaneously. We further developed the method to incorporate isobaric tags such as a tandem mass tag (TMT) and used it to discover novel peptides during ER stress analysis. The iNrich facilitated high-throughput N-terminomics and degradomics at a low cost using commercially available reagents and apparatus, without requiring arduous procedures.Despite being researched for nearly five decades, chemical application of metallic glass is scarcely explored. Here we show electrochemical nonenzymatic glucose-sensing ability of nickel-niobium (Ni60Nb40) amorphous alloys in alkaline medium. Three different Ni60Nb40 systems with the same elemental composition, but varying microstructures are created following different synthetic routes and tested for their glucose-sensing performance. Among melt-spun ribbon, nanoglass, and amorphous-crystalline nanocomposite materials, nanoglass showed the best performance in terms of high anodic current density, sensitivity (20 mA cm-2 mM-1), limit of detection (100 nM glucose), stability, reproducibility (above 5000 cycles), and sensing accuracy among nonenzymatic glucose sensors involving amorphous alloys. When annealed under vacuum, only the heat-treated nanoglass retained a similar electrochemical-sensing property, while the other materials failed to yield desired results. In nanoglass, a network of glassy interfaces, compared to melt-spun ribbon, is plausibly responsible for the enhanced sensitivity.Background Brain metastasis is a major cause for cancer death in patients with lung cancer. Sirtuin 1 (SIRT1) and hsa-miR-217 has been identified to mediate the development of non-small cell lung cancer (NSCLC). Aims We performed this study to investigate the roles of hsa-miR-217, its target SIRT1, as well as P53/KAI1 axis in the brain metastasis from NSCLC. TAPI-1 Immunology inhibitor Study design This is a cell culture study. Methods Human pulmonary adenocarcinoma brain metastasis cell line PC-14/B were incubated and treated with constructed lentiviral plasmids expressing miR-217 and/or SIRT1. BEAS-2B cell line was used as a control. The targeted regulation of miR-217 to SIRT1 was examined using dual luciferase reporter assay. Cell proliferation, migration, invasion and the expression of relate proteins were detected to examine the effect of miR-217/SIRT1 expression on metastasis. Results PC-14/B cells expressed higher SIRT1 and lower p53 and KAI1 compared with BEAS-2B control cells (P less then 0.05). SIRT1 was a direct target of miR-217. MiR-217 expression suppressed PC-14/B cell invasion (P=0.004), migration (P=0.001) and proliferation (P less then 0.05), whereas SIRT1 overexpression reversed all processes. SIRT1 expression inhibited P53, KAI1/CD82, matrix metalloproteinase (MMP)-9 and β-catenin but upregulated E-cadherin protein. MiR-217 overexpression induced reverse changes. Conclusions Hsa-miR-217 and its target SIRT1 acted as metastasis suppressor and promoter gene in NSCLC, respectively. The hsa-miR-217/SIRT1/P53/KAI1 metastasis regulatory pathway showed novel and crucial roles in brain metastasis from NSCLC. This axis might be a potential target for the treatment of brain metastasis of lung cancer.The objective of this paper was the analysis of the 1-year outcome of teeth treated with apical surgery and a recently introduced bioceramic root repair material (BCRRM) for root-end filling. Patients were consecutively enrolled from 2015 to 2017. Apical surgery included the modern technique, i.e. the use of a surgical microscope, ultrasonic preparation of a root-end cavity, and retrofilling with BCRRM. The cohort comprised 150 patients with 174 treated teeth. Patients were recalled one year after surgery for a clinical and radiographic re-examination. Three experienced observers evaluated the periapical radiographs with regard to periapical healing utilizing the healing criteria established by Rud et al. (1972) and Molven et al. (1987). Based on the clinical findings and the radiographic assessment, healing was judged as successful, uncertain, or failed. Study parameters included gender, age, type of treated tooth, and type of BCRRM (regular vs. fast set putty). At the 1-year follow-up, 170 teeth could be reexamined (drop-out rate 2.3%). Healing outcome was categorized as successful in 94.1%, uncertain in 4.1%, and failed in 1.8%. No significant differences were observed when comparing the success rates among the different subcategories of study parameters. The lowest success rate was noted in mandibular premolars (86.7%) but without reaching statistical significance. In conclusion, BCRRM appears to be a biocompatible root-end filling material showing excellent 1-year results. The success rate was similar to recently reported success rates for BCRRM in apical surgery.Uterine leiomyomata are the most frequent leiomyomata. However, this benign tumor can also arise in unusual locations (e.g. ovaries, urethra, bladder and vulva). The diagnostic process of ovarian leiomyomata can be difficult, and it is mostly incidental the lesions are usually small and the clinical presentation is mainly asymptomatic. Since the first case described in 1862, less than 100 cases have been described. Some of these lesions have been treated laparoscopically. To our knowledge, this is the first worldwide case of an ovarian leiomyoma treated with a robotic approach (surgeon Prof. P.C. Giulianotti, M.D., F.A.C.S.). Moreover, we provide an overview of the recent literature, and an intraoperative video of the intervention.
