sence of inflammation, may be protective. The therapeutic role of pelvic and para-aortic lymphadenectomy in surgical staging of apparent early-stage epithelial ovarian cancer (eEOC) is still under debate. https://www.selleckchem.com/products/gdc-0068.html The aim of this study was to evaluate the potential therapeutic role of systematic lymphadenectomy in patients with eEOC. Multi-center retrospective cohort study, comparing women with apparent eEOC who underwent comprehensive bilateral pelvic and para-aortic lymphadenectomy (defined as ≥20 lymph nodes) versus patients receiving no lymphadenectomy or lymph node sampling, from 05/1985 to 12/2016. Patients with bulky nodes at CT-scan and those without complete intra-peritoneal surgical staging were excluded. Only patients who received at least 3cycles of platinum-based adjuvant chemotherapy were included. Out of 2559 patients with FIGO stage IA-IIIA1 ovarian cancer, 639 (25.0%) met inclusion criteria. 360 (56.3%) underwent comprehensive lymphadenectomy, 150 (23.5%) lymph node sampling and 129 (20.2%) no lymphadenectomy. Patients who underwent comrgical staging of eEOC improves DFS for the price of increasing post-operative complications and time to chemotherapy but does not affect OS. Better understanding of tumor biology may help to identify those patients in whom lymphadenectomy should still play a role.Decreasing the soil organic carbon (SOC) decomposition is critical to improve the quality of the soil and mitigate atmospheric CO2 emissions. To improve the ability to protect the SOC by optimizing tillage management, this study investigated the laboratory-based SOC mineralization (decomposition) and soil chemical properties under different tillage practices, including no tillage with straw mulch (NTS), rotary tillage with straw incorporated (RTS), moldboard plow tillage with straw incorporated (CTS) and moldboard plow tillage with straw removal (CT). Soil samples of six sampling dates from April 2017 to October 2018 were incubated at 25 °C and 70% water holding capacity for 60 d. Repeated Variance Analyses were conducted to compare the means of different treatments. The results showed that the average cumulative SOC mineralization (Cm) at the 0-5 cm soil depth was 7.09 g CO2 kg-1 soil under NTS, which was higher (P less then 0.05) than that of the other treatments. However, the C mineralizability at both the 0-5 and 5-10 cm soil depths were lower (P less then 0.05) under the NTS (0.16 and 0.15 g CO2 g-1 SOC) compared with the CTS and CT. Non-microbial CO2 emissions (CO2 emissions in sterilized soil) contributed to the lower C mineralizability under NTS, due to the lower mineralizability (0.041-0.089 g CO2 g-1 SOC) of sterilized soil under this treatment. Furthermore, some of the abiotic factors (e.g., C/N ratio and SOC content) significantly correlated with the Cm and C mineralizability. These factors might be critical for the ability to protect SOC under NTS. In summary, conservation tillage is an optimal management due to its protection on SOC, and part of this protection appeared to have been contributed by the soil abiotic factors, which were formed by long-term tillage management.Alum sludge, an Al-oxyhydroxide rich waste product from water treatment practices, has the potential to be valorized as a P adsorbent material. However, several challenges currently prevent its application as an adsorbent in industrial setting, i.e. a limited P adsorption capacity due to saturation by organic matter and a fine nature resulting in percolation problems in adsorption bed setups. In this study, granulation and subsequent calcination of alum sludge were proposed to overcome these issues and to improve the P adsorption properties of alum-based adsorbent (ABA) materials. The effect of calcination temperature on the physicochemical properties of granular material was examined using X-ray diffraction, mass-spectroscopy coupled thermogravimetric analysis, Fourier-transform infrared spectrometry and specific surface area analysis, combined with density and crushing strength measurements. The ABA material obtained at 550 °C showed superior P adsorption properties and, therefore, this material was selected for further P adsorption testing and characterization (scanning electron microscopy and sieving). Batch P adsorption tests showed that this material had a maximum P adsorption capacity of 7.27 mg-P g-1. Kinetic adsorption tests determined the effect of the solid-to-liquid ratio and the granule particle size on the P removal. Finally, the performance of the ABA-550 material was tested in a pilot-scale adsorption setup, using a surface water stream (0.47 mg-P L-1) at a flow rate of 200 L h-1. During the test, the P removal efficiency always exceeded 86%, while the material maintained its structural stability. The results of this study illustrate the potential of granulated/calcined ABA materials for P adsorption, paving the way for the industrial application of this novel, sustainable P removal technology.The present study aimed to investigate the copper distribution in a river through the integrated utilization of the soil hydrological assessment model and water quality model. The Erren River was selected as the investigated river system because an apparent heavy metal pollution was observed. The Soil and Water Assessment Tool (SWAT) was employed to estimate the soil flux. The Water Quality Analysis Simulation Program Model (WASP) was used for water quality simulation. The copper was selected as the model chemical and scenarios of various copper effluent control measures and impacts of the heavy rainfall by climate change on copper concentration were simulated. The results showed that the aqueous copper was adsorbed to suspended solids and the high aqueous copper concentration resulted in a high copper concentration in the sediment. In dry seasons, the aqueous copper concentration increased 215% comparing to the 2006-2016 average (baseline) concentration and a 20% decrease in copper concentration in the sediment was observed due to less wash-out solid. Under the impact of enhanced rainfall by climate change, the aqueous copper concentration decreased due to the increased river flow, which also reduced the copper deposition causing the copper concentration in the sediment lower than that in the baseline condition. In the middle and downstream river sections, the copper concentration in the water and sediment phases decreased around 66% by implementing a more-stringent effluent standard. The suspended solid played a key role for copper movement in a river. The copper accumulation in the sediment might be alleviated by reducing its aqueous concentration.
