The GMT-Consortium Large Earth Finder (G-CLEF) will be a cross-dispersed, optical band echelle spectrograph to be delivered as the first light scientific instrument for the Giant Magellan Telescope (GMT) in 2022. G-CLEF is vacuum enclosed and fiber-fed to enable precision radial velocity (PRV) measurements, especially for the detection and characterization of low-mass exoplanets orbiting solar-type stars. The passband of G-CLEF is broad, extending from 3500Å to 9500Å. This passband provides good sensitivity ...

Long intergenic non-coding RNAs (lincRNAs) have historically been ignored in cancer biology. However, thousands of lincRNAs have been identified in mammals using recently developed genomic tools, including microarray and high-throughput RNA sequencing (RNA-seq). Several of the lincRNAs identified have been well characterized for their functions in carcinogenesis. Here we performed RNA-seq experiments comparing gastric cancer with normal tissues to find differentially expressed transcripts in intergenic ...

Abstract The effectiveness of most cancer targeted therapies is short-lived. Tumors often develop resistance that might be overcome with drug combinations. However, the number of possible combinations is vast, necessitating data-driven approaches to find optimal patient-specific treatments. Here we report AstraZeneca’s large drug combination dataset, consisting of 11,576 experiments from 910 combinations across 85 molecularly characterized cancer cell lines, and results of a DREAM Challenge to evaluate ...

We report on a new technique that incorporates silver nanoparticles (AgNPs) onto polyamide (PA) thin film composite (TFC) reverse osmosis membranes via arc plasma deposition (APD) to impart antibacterial properties and simultaneously improve membrane performance. APD allows the direct deposition of AgNPs under vacuum dry condition, overcoming the drawbacks of the conventional wet-chemical methods. AgNPs (~7.6 nm in diameter) were uniformly distributed without aggregation throughout the PA selective layer ...

We present a new strategy to strongly and effectively immobilize silver nanoparticles (AgNPs) on polyamide thin film composite membranes to endow antibacterial activity. This method relies on the immobilization of relatively large silica particles (SiO2, ~400 nm in diameter), where AgNPs of ~30 nm in diameter are tightly and densely bound (AgNP@SiO2), on the membrane surface using cysteamine as a covalent linker. The formation of multiple Ag–S chemical bonds between a “bumpy” AgNP@SiO2 and the rough membrane ...

Fouling is a long-standing problem in water treatment membranes because it substantially deteriorates process efficiency. Here, we present a facile strategy for the in situ modification of polyethersulfone (PES) ultrafiltration (UF) membranes with eco-friendly antifouling materials (i.e., pyrogallol and taurine) to enhance their fouling resistance. When the PES dope solution was immersed into the nonsolvent containing pyrogallol and taurine, the phase separation and surface modification of the PES ...

We demonstrate a simple pulsed CO2 laser with long pulse duration of millisecond order in a tube at a low pressure of less than 30 Torr. The power supply for our laser system switches the voltage of the ac power line (60 Hz) directly. The power supply does not need elements such as a rectifier bridge, energy-storage capacitors, or a current-limiting resistor in the discharge circuit. In order to control the laser output power, the pulse repetition rate is adjusted up to 60 Hz and the firing angle ...

The cell proliferation of p53-deficient Jurkat T cells is controlled after prolonged exposure to human lactoferrin (Lf). However, the molecular mechanism by which Lf influences these cellular responses remains unclear. In this study, we demonstrate that Lf-induced apoptosis in Jurkat T cells occurs in a dose- and time-dependent manner via the regulation of c-Jun N-terminal kinase (JNK) activity. Jurkat cells exposed to Lf for 1 day, especially at concentrations in excess of 500 μg/ml, showed typical ...

Background and objective: The effective control of tuberculosis (TB) requires that people at high risk for the reactivation of TB are identified. Haematological malignancy has been shown to be a risk factor for the development of TB, either through immune suppression by the tumour or through the effects of chemotherapy.
