Disulfiram (DSF) in combination with copper (Cu) has been reported to override drug resistance in cancer cells, and DSF combined with chemotherapy based on the microtubule inhibitor vinorelbine appears to prolong survival in non-small cell lung cancer patients. Here, we investigated the mechanisms underlying these findings. DSF/Cu reversed the microtubule inhibitor resistance in A549/Taxol and KB/VCR cells in vitro, and had anti-tumor effects in A549/Taxol and KB/VCR xenograft mice. DSF/Cu and DSF reduced the cancer stem cell (CSC) characteristics of drug-resistant A549/Taxol and KB/VCR cells, including sphere formation, colony generation and migration, and DSF/Cu was more effective than DSF alone...

Eutrophication and undesired algal blooms in surface water are common and have been linked to increasing nutrient loading. Effects of extreme events such as storms on reservoir nutrient and phytoplankton remain unclear. Here we carried out continuous high-frequency measurements in a long and narrow dam reservoir in southeast China during a storm period in June-July 2015. Our results show a strong nutrient-phytoplankton relationship as well as a very rapid response to storm runoff. We observed an increase in total suspended matter (TSM), ammonium (NH4-N), and dissolved reactive phosphate (DRP), with a sharp decline in chlorophyll-a (Chl-a) in the high flow periods...

Doxorubicin (DOX) has been widely used to treat cancers as a first‑line antitumor drug. However, it causes severe, irreversible, dose‑dependent cardiotoxicity. To evaluate the protective effects of naringin (NRG) on cardiotoxicity, the authors investigated the molecular mechanism of the p38MAPK signaling pathway. H9c2 cells were treated for 24 h by using 5 µmol/l DOX without or with being pretreated by 1 µM NRG for 150 min or by 3 µM SB203580 for 60 min. Cell viability was detected by cell counting kit‑8 assay...

Although salt-tolerant plants can be used to combat dryland salinity, these plants contain high concentrations of salt (NaCl), which may have deleterious effects if fed to livestock. Twenty-four Merino rams (9 mo of age) with similar body weight were equally allocated to two groups and fed a normal- or high-salt diet (0.5 and 12% NaCl, respectively) for 3 mo. Rams fed the high-salt diet had lower live weight gains, higher water intake, smaller testes (466 ± 48.4 vs 604 ± 51.1 g) and reductions (P <0...

Late-stage hepatocellular carcinoma (HCC) usually has a low survival rate because of the high risk of metastases and the lack of an effective cure. Disulfiram (DSF) has copper (Cu)-dependent anticancer properties in vitro and in vivo. The present work aims to explore the anti-metastasis effects and molecular mechanisms of DSF/Cu on HCC cells both in vitro and in vivo. The results showed that DSF inhibited the proliferation, migration and invasion of HCC cells. Cu improved the anti-metastatic activity of DSF, while Cu alone had no effect...

Four isostructural lanthanide coordination polymers with a phenylacetate (PAA(-)) ligand, [Ln(PAA)3(H2O)]n (Ln = Eu (1); Gd (2); Tb (3); Dy (4)), were synthesized under hydrothermal conditions. Complexes 1-4 display a one-dimensional (1D) wave chain structure bridged by the carboxylate of the PAA(-) ligand, which was generated via the in situ decarboxylation of phenylmalonic acid. Magnetic studies suggest the presence of ferromagnetic LnLn coupling in the 1D chain of 1-4. Meanwhile, 2 has a significant cryogenic magnetocaloric effect with the maximum -ΔSm of 26...

Although several serine collagenolytic proteases from bacteria were reported, none has been used to prepare bioactive collagen peptides. MCP-01 is the most abundant extracellular protease of deep-sea Pseudoalteromonas sp. SM9913 and is a serine collagenolytic protease with high efficiency on fish collagen hydrolysis. Here, we set up a pilot scale process to ferment SM9913 for extracellular protease production. With SM9913 extracellular protease as a tool, a process to prepare collagen oligopeptide-rich hydrolysate from codfish skin was set up, which was further scaled up to pilot (100 L) and plant (2000 L) levels with yields >66%...

In this paper, we propose a new visual-inertial Simultaneous Localization and Mapping (SLAM) algorithm. With the tightly coupled sensor fusion of a global shutter monocular camera and a low-cost Inertial Measurement Unit (IMU), this algorithm is able to achieve robust and real-time estimates of the sensor poses in unknown environment. To address the real-time visual-inertial fusion problem, we present a parallel framework with a novel IMU initialization method. Our algorithm also benefits from the novel IMU factor, the continuous preintegration method, the vision factor of directional error, the separability trick and the robust initialization criterion which can efficiently output reliable estimates in real-time on modern Central Processing Unit (CPU)...
