Remediation of a Mercury-Contaminated Industrial Soil Using Bioavailable Contaminant Stripping

Pedosphere 2013年第1期23卷 104-110页

The method to remove bioavailable amounts of heavy metals from a contaminated soil by using plants is defined as bioavailable contaminant stripping （BCS） and could safely be applied if the soil＇s long-term ability to replenish the bioavuilable pool is known. The aim of this study was to evaluate the ability of three common plant species selected, Brassica juncea, Poa annua, and Helianthus annus, to remove bioavailable amounts of mercury （Hg） from a contaminated industrial soil containing 15.1 mg kg-1 Hg. Trials were carried out under greenhouse conditions using pots （mesocosms）. According to the precautionary principle, we modified the BCS remediation approach by adding a new step, in which mercury bioavailability was increased by the addition of a strong mobilizing agent, ammonium thiosulphate, （NH4）28203, to obtain an estimate of the likely long-term bioavailable Hg pool. The modified BCS remediation approach was called enhanced bioavailable contaminant stripping （EBCS）. After one growth cycle, nearly all the bioavailable mercury （95.7%） was removed and the metal remaining in the soil was considered inert since it was neither extractable by （NH4）2S2O3 nor taken up by plants during a second growth cycle. The results demonstrated that EBCS appeared promising since it removed the most dangerous metal forms while substantially shortening the cleanup time.

Primary sclerosing cholangitis: Updates in diagnosis and therapy

引用

World Journal of gastroenterology 2005年第1期11卷 7-16页

Primary sclerosing cholangitis (PSC) is a chronic cholestatic syndrome of unknown origin mostly found in males, and characterized by diffuse inflammation and fibrosis of both intra- and extra-hepatic bile ducts. So far, PSC is considered as an autoimmune hepatobiliary disease. In most cases the progression of PSC towards liver cirrhosis and liver failure is slow but irreversible, and liver transplantation is currently the only definitive treatment. In recent years,PSC has been an area of active research worldwide with great interest in etiology, pathogenesis, diagnosis, and therapeutic options such as hydrophilic ursodeoxycholic acid and immunosuppressive agent tacrolimus. Recent updates on clinical and therapeutic aspects of PSC are discussed in the present review.

Successful robot-assisted surgery for treating endometrial cancer affecting bicornuate-bicollis or didelphic uterus

Open Journal of Obstetrics and gynecology 2013年第5期3卷 15-18页

Uterine anomalies are mainly associated with improper development of Mullerian ducts. To our knowledge, reports describing the use of a da Vinci Robot System for treating an endometrial cancer in a woman with an abnormal uterus are lacking. Here, we reported the description of two extremely obese women, affected by endometrial cancer and presenting bicornuate-bicollis and didelphic uterus have been treated by Robot System-assisted surgery. No operative and postoperative complications were recorded. Both women are disease-free to follow-up. A robot-assisted surgery could represent an effective treatment option for complex hysterectomies and in complicated patients, as those showing an extreme obesity.

Dear Editor,Soil quality is defined as"the capacity of a soil to function,within ecosystem and land use boundaries,to sustain productivity,maintain environmental quality,and promote plant and animal health"(Doran and Parkin 1994).In this context,soil functionality is fundamental to the biosphere and is highly dependent on the associated *** microorganisms are relevant for terrestrial ecosystem functioning,and understanding the functional changes of the biological community in diverse soils is relevant for monitoring soil quality and developing actions to mitigate soil degradation(Madsen,2008;Delgado-Baquerizo et al.,2021).

To compare our developed nerve preserving technique with the non-nerve preserving one in terms of de novo bowel symptoms. METHODSPatients affected by symptomatic apical prolapse, admitted to our department and treated by nerve preserving laparoscopic sacropexy (LSP) between October, 2010 and April, 2013 (group A or “interventional group”) were compared to those treated with the standard LSP, between September, 2007 and December, 2009 (group B or “control group”). Functional and anatomical data were recorded prospectively at the first clinical review, at 1, 6 mo, and every postsurgical year. Questionnaires were filled in by the patients at each follow-up clinical evaluation. RESULTSForty-three women were enrolled, 25/43 were treated by our nerve preserving technique and 18/43 by the standard one. The data from the interventional group were collected at a similar follow-up (> 18 mo) as those collected for the control group. No cases of de novo bowel dysfunction were observed in group A against 4 cases in group B (P = 0.02). Obstructed defecation syndrome (ODS) was highlighted by an increase in specific questionnaires scores and documented by the anorectal manometry. There were no cases of de novo constipation in the two groups. No major intraoperative complications were reported for our technique and it took no longer than the standard procedure. Apical recurrence and late complications were comparable in the two groups. CONCLUSIONOur nerve preserving technique seems superior in terms of prevention of de novo bowel dysfunction compared to the standard one and had no major intraoperative complications.
