Background:Despite remarkable advances in surgical techniques and perioperative management,left hepatic trisectionectomy(LHT)remains a challenging procedure with a somewhat high postoperative morbidity rate compared with less-extensive *** study aimed to analyze the short-and long-term outcomes of LHT and identify factors associated with the postoperative morbidity of this technically demanding surgical ***:The medical records of 53 patients who underwent LHT between june 2005 and October 2019 at a single institution were retrospectively *** independent prognostic factor of postoperative morbidity was analyzed using the logistic regression ***:Hepatocellular carcinoma was the most common indication for surgery(n=21),followed by hilar cholangiocarcinoma(n=14),intrahepatic cholangiocarcinoma(n=10),and other pathologies(including colorectal liver metastasis,hepatolithiasis,gallbladder cancer,living donor,hemangioma,and multilocular biliary cyst;n=8).The rates of postoperative morbidities of Clavien-Dindo grade 3 or higher and 90-day mortality were 39.6% and 1.9%,*** 1-,3-,and 5-year overall survival rates were 81.1%,61.4%,and 44.6%,*** analysis revealed that preoperative jaundice[hazard ratio(HR)=6.15,95%confidence interval(CI):1.57-24.17,P=0.009]and operative time>420 min(HR=4.66,95%CI:1.27–17.17,P=0.021)were independent predictors of postoperative ***:The in-hospital mortality of LHT surgery can be minimalized by a reliable preoperative evaluation of liver function and selection of the dominant anatomic features of right posterior sector,active and appropriate preoperative management for obstructive cholangitis and compensatory hypertrophy of the future remnant posterior sector,and the experience of the surgeon.

Maximizing biomass utilization: An integrated strategy for coproducing multiple chemicals

引用

Journal of Energy Chemistry 2025年第1期100卷 180-191页

作者： Byeongchan Ahn Sua Jo Jonggeol Na J.Jay Liu Young-ju kim Wangyun Won Department of Chemical and Biological Engineering Korea University Department of Chemical Engineering (Integrated process) Kyung Hee University Department of Chemical Engineering and Materials Science Ewha Womans University Department of Chemical Engineering Pukyong National University Resources Engineering Plant Research Department Korea Institute of Geoscience and Mineral Resources

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol（1,6-HDO） with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments（LCAs）.Strategy A was found to be the most favorable both economically（USRDSCHARDOLLAR3,402/ton） and environmentally（-26.9 kg CO2eq.）. This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.

Dyes wastewater treatment by reduction-oxidation process in an electrochemical reactor packed with natural manganese mineral

引用

Journal of Environmental Sciences 2006年第1期18卷 17-22页

作者： WANG Ai-min QU Jiu-hui LIU hui-juan LEI Peng-ju State Key Laboratory of Environmental Aquatic Chemistry Research Center for Eco-Environmental Sciences Chinese Academy of Sciences Beijing 100085 China

A novel technology which combined electrochemical process catalyzed by manganese mineral with electro-assisted coagulation process was proposed in this study. The mineralization of organic pollutant from simulated dye wastewater containing an azo dye Acid Red B（ARB） was experimentally investigated using this method. It was found that the manganese mineral could catalyze the electrochemical process dramatically. The TOC removal percentage of electrochemical treatment catalyzed by manganese mineral was 43.6% while the TOC removal percentage of the process using the manganese mineral alone and using the electrolysis alone were 9.3% and 20.8%, respectively. Moreover, it was found that combined electroxidation with electro-assisted coagulation process could more effectively eliminate ARB. After a period of 180 min electrooxidation and 300 min electroreduction, almost 66.9% of TOC was removed, and the dissolved Mn^2＋. could be effectivly removed. The effects of the order of oxidation and reduction, the proper ratio electrooxidation/reduction time, and current density on the removal efficiency were investigated in detail. In addition, a proposed mechanism of manganese-mineral-catalyzed electrooxidation-reduction process was discussed in this paper.
