1Combined Chemical and Mineralogical Evidence for Heavy Metal Binding in Mining- and Smelting-Affected Alluvial Soils显示文摘The binding of metallic contaminants (Pb, Cd, and Zn) and As on soil constituents was studied on four highly con-taminated alluvial soil profiles from the mining/smelting district of Píbram (Czech Republic) using a combination of mineralogical and chemical methods. Sequential extraction analysis (SEA) was supplemented by mineralogical investi-gation of both bulk samples and heavy mineral fractions using X-ray diffraction analysis (XRD) and scanning electron microscopy with an energy dispersive X-ray spectrometer (SEM/EDS). The mineralogy of Fe and Mn oxides was studied by voltammetry of microparticles (VMP) and diffuse reflectance spectrometry (DRS). Zinc and Pb were predominantly bound in the reducible fraction attributed to Fe oxides and Mn oxides (mainly birnessite, Na4Mn14O27·9H2O), which were detected in soils by XRD and SEM/EDS. In contrast, Cd was the most mobile contaminant and was predominantly present in the exchangeable fraction. Arsenic was bound to the residual and reducible fractions (corresponding to Fe oxides or to unidentified Fe-Pb arsenates). SEM/EDS observations indicate the predominant affnity of Pb for Mn oxides, and to a lesser extent, for Fe oxides. Thus, a more suitable SEA procedure should be used for these mining-affected soils to distinguish between the contaminant fraction bound to Mn oxides and Fe oxides.A. VANEK V. ETTLER T. GRYGAR L.

2Delaying surgery after neoadjuvant chemoradiotherapy improves prognosis of rectal cancer显示文摘AIM To investigate the prognostic effect of a delayed interval between neoadjuvant chemoradiotherapy(CRT) and surgery in locally advanced rectal cancer.METHODS We evaluated 87 patients with locally advanced mid-or distal rectal cancer undergoing total mesorectal excision following an interval period after neoadjuvant CRT at ?i?li Hamidiye Etfal Training and Research Hospital,Istanbul between January 2009 and January 2014.Patients were divided into two groups according to the intervalbefore surgery: < 8 wk(group Ⅰ) and ≥ 8 wk(group Ⅱ).Data related to patients,cancer characteristics and pathological examination were collected and analyzed.RESULTS When the distribution of timing between group Ⅰ(n = 45) and group Ⅱ(n = 42) was viewed,comparison of interval periods(median ± SD) of groups showed a significant difference of as 5 ± 1.28 wk in group Ⅰ and 10.1 ± 2.2 wk in group Ⅱ(P < 0.001).The median follow-up period for all patients was 34.5(9.9-81) mo.group Ⅱ had significantly higher rates of pathological complete response(p CR) than group Ⅰ had(19% vs 8.9%,P = 0.002).Rate of tumor regression grade(TRG) poor response was 44.4% in group Ⅰ and 9.5% in group Ⅱ(P < 0.002).A poor pathological response was associated with worse disease-free survival(P = 0.009).The interval time did not show any association with local recurrence(P = 0.79).CONCLUSION Delaying the neoadjuvant CRT-surgery interval may provide nodal down-staging,improve p CR rate,and decrease the rate of TRG poor response.Mehmet Mihmanli Esin Kabul Gürbulak Ismail Ethem Akgün Mustafa Fevzi Celayir Pinar Yazici Deniz Tuncel Tuba Tülin Bek Ayhan Oz Sinan Omeroglu 2016World Journal of Gastrointestinal Oncology2016,8,9:3
