Beneficial effects of preventive cholecystectomy in patients with hepatic cancer

LIU Anzhong, LI Jun, HUA Huwei

Frontiers of Medicine 2008, Volume 2, Issue 2, Pages 139-142 doi: 10.1007/s11684-008-0026-x

Abstract: There is no conclusive answer to the question whether excising gall bladder is helpful to the patient with hepatic cancer. The survival rate of patients with hepatic cancer for more than two years has been increased, and the incidence of complications of cholecystitis and gall stone are relatively higher among these patients, which may seriously complicate treatment of advanced hepatic cancer and decrease quality of life. The researchers conducted a prospective clinical investigation from 2002 to 2006 to assess the clinical significance of preventive cholecystectomy in patients with hepatic cancer. One hundred and eighteen cases of postoperative patients with hepatic cancer, who survived for more than two years, were followed up. Based on whether cholecystectomy was performed, the patients were divided into two groups including 48 cases with cholecystectomy and 70 cases with cholecyst reserved. The two-year morbidity of gall stone and morbidity of pain in the right upper abdomen of cholecyst reservation group were 54.29% and 68.57%, respectively, obviously higher than 0.00% and 20.83% of cholecystectomy group. Mainly for those treated with transcatheter arterial chemo-embolization, the morbidity of gall stone was 86.67% ( < 0.01). Therefore, preventive cholecystectomy is strongly recommended during hepatectomy to decrease the incidence of chronic cholecystitis and gall stone, especially for those whose chemotherapy and embolization will be carried out through hepatic artery and portal vein.

Chromium steel from chromite ore processing residue----A valuable construction material from a waste

Jay N. MEEGODA, Wiwat KAMOLPORNWIJIT

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 2, Pages 159-166 doi: 10.1007/s11783-011-0325-3

Abstract: As species we humans generate excessive amounts of waste and hence for sustainability we should explore innovative ways to recover them. The primary objective of this study is to demonstrate an efficient and optimum way to recover chromium and iron from chromite ore processing residues (COPR) for the production of chrome steel and stainless steel. In Hudson County, New Jersey, there are more than two million tons of leftover COPR. Part of COPR was used as fill materials for construction sites, which spread the problem to a larger area. With high solubility along with their toxicity leached chromate from COPR is threatening the environment as well as human health. In this research, COPR was thermally treated to recover iron with chromium by applying techniques used in steel manufacturing. An extensive experimental program was performed using a Thermo-Gravimetric Analyzer (TGA) and bench scale tests to thermally treat the processed chromium contaminated soils with carbon and sand at varying temperatures and under reducing environment. The optimum chemical composition of COPR and additives to be used in the melts were evaluated based upon the thermodynamic properties of the mixture to ensure good phase separation, least amounts of iron and chromium oxides in the slag and minimum variability of final product (steel or iron with chromium). The impact of other oxides on the steel making process was evaluated to minimize the adverse impact on the process. The research demonstrated the feasibility of recovering a valuable construction material (chrome steel) from a waste (COPR).

Microbiome Engineering: A Promising Approach to Improve Coral Health

Jie Li,Qingsong Yang,Junde Dong,Michael Sweet,Ying Zhang,Cong Liu,Yanying Zhang,Xiaoyu Tang,Wenqian Zhang,Si Zhang,

Engineering doi: 10.1016/j.eng.2022.07.010

Abstract: The world’s coral reefs are threatened by the cumulative impacts of global climate change and local stressors. Driven largely by a desire to understand the interactions between corals and their symbiotic microorganisms, and to use this knowledge to eventually improve coral health, interest in coral microbiology and the coral microbiome has increased in recent years. In this review, we summarize the role of the coral microbiome in maintaining a healthy metaorganism by providing nutrients, support for growth and development, protection against pathogens, and mitigation of environmental stressors. We explore the concept of coral microbiome engineering, that is, precise and controlled manipulation of the coral microbiome to aid and enhance coral resilience and tolerance in the changing oceans. Although coral microbiome engineering is clearly in its infancy, several recent breakthroughs indicate that such engineering is an effective tool for restoration and preservation of these valuable ecosystems. To assist with identifying future research targets, we have reviewed the common principles of microbiome engineering and its applications in improving human health and agricultural productivity, drawing parallels to where coral microbiome engineering can advance in the not-too-distant future. Finally, we end by discussing the challenges faced by researchers and practitioners in the application of microbiome engineering in coral reefs and provide recommendations for future work.

Carbon dioxide industrial chain born in desert control—a case from Mau Us Thermoelectric factory“three-carbon economy”

Li Jinglu

Strategic Study of Chinese Academy of Engineering 2011, Volume 13, Issue 2, Pages 63-65

Abstract:

A "three-carbon economy" is introduced in this article which includes three parts: planting sandy shrub to prevent and control desertification, generating electricity with shrub branches, and feeding spirulina with the smoke. The three parts are also correspondingly the process of CO₂ absorption, carbon emission reduction, and carbon capture, forming a carbon industrial chain. This chain makes the farmers initiatively plant shrubs in sand, and desert control turns to easy thing by benefiting the bio-power factory, the farmers, and also the environments. This industrial chain will contribute to our national desert control strategy.

Harnessing the Beneficial Attributes of Ceria and Titania in a Mixed-Oxide Support for Nickel-Catalyzed Article

Ee Teng Kho,Salina Jantarang,Zhaoke Zheng,Jason Scott,Rose Amal

Engineering 2017, Volume 3, Issue 3, Pages 393-401 doi: 10.1016/J.ENG.2017.03.016

Abstract:

Solar-powered carbon dioxide (CO₂)-to-fuel conversion presents itself as an ideal solution for both CO₂ mitigation and the rapidly growing world energy demand. In this work, the heating effect of light irradiation onto a bed of supported nickel (Ni) catalyst was utilized to facilitate CO₂ conversion. Ceria (CeO₂)-titania (TiO₂) oxide supports of different compositions were employed and their effects on photothermal CO₂ conversion examined. Two factors are shown to be crucial for instigating photothermal CO₂ methanation activity: ① Fine nickel deposits are required for both higher active catalyst area and greater light absorption capacity for the initial heating of the catalyst bed; and ② the presence of defect sites on the support are necessary to promote adsorption of CO₂ for its subsequent activation. Titania inclusion within the support plays a crucial role in maintaining the oxygen vacancy defect sites on the (titanium-doped) cerium oxide. The combination of elevated light absorption and stabilized reduced states for CO₂ adsorption subsequently invokes effective photothermal CO₂ methanation when the ceria and titania are blended in the ideal ratio(s).
