BACKGROUND: Ramucirumab is a recombinant human IgG1 neutralizing monoclonal antibody specific for vascular endothelial growth factor receptor-2. Second-line ramucirumab, in conjunction with paclitaxel (ramucirumab 8 mg/kg or placebo in combination with 80 mg/m(2) paclitaxel), has been shown to be effective and safe in patients with advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma in RAINBOW, a global phase III randomized clinical trial. We conducted an exploratory exposure-response analysis of efficacy and safety of ramucirumab in East Asian patients from the RAINBOW trial...

Despite intensive multi-modal treatment of sarcomas, a heterogeneous group of malignant tumors arising from connective tissue, survival remains poor. Candidate-based targeted treatments have demonstrated limited clinical success, urging an unbiased and comprehensive analysis of oncogenic signaling networks to reveal therapeutic targets and personalized treatment strategies. Here we applied mass spectrometry-based phosphoproteomic profiling to the largest and most heterogeneous set of sarcoma cell lines characterized to date and identified novel tyrosine phosphorylation patterns, enhanced tyrosine kinases in specific subtypes, and potential driver kinases...

Anaerobic mono- and co-digestion of sewage sludge (SS) and food waste leachate (FWL) were performed by assessing methane production and characterizing microbial communities. Anaerobic digestion (AD) of waste activated sludge (WAS) alone produced the lowest methane production (281 mL-CH4), but an approximately 80% increase in methane production was achieved via co-digestion of WAS and FWL (506 mL-CH4). There were less differences in the diversity of bacterial communities in anaerobic digesters, while archaeal (ARC) and bacterial (BAC) amounts reflected AD's performance...

The goal of this study was to predict the structural response of the femoral shaft under dynamic loading conditions using subject-specific finite element (SS-FE) models and to evaluate the prediction accuracy of the models in relation to the model complexity. In total, SS-FE models of 31 femur specimens were developed. Using those models, dynamic three-point bending and combined loading tests (bending with four different levels of axial compression) of bare femurs were simulated, and the prediction capabilities of five different levels of model complexity were evaluated based on the impact force time histories: baseline, mass-based scaled, structure-based scaled, geometric SS-FE, and heterogenized SS-FE models...

Development of low cost, environmental friendly crystal growth modifying reagents that are effective to HAp's microstructure regulation is highly crucial. Herein, sodium lignin sulfonate (SS), a byproduct of the pulp process, was used for preparing HAp nanorods. Results showed that both stirring time of reaction solution and the concentration of SS affected crystals' structure and aspect ratio. The growth mechanism was discussed on the basis of the results. And we hope this new synthetic strategy will offer an attractive route for the design of functional HAp nano-/micro- materials with fine structure...
