2Dioxygen Affinity and Catalytic Performance of Bis-(furaldehyde) Schiff Bases Co(II) Complexes in Cyclohexene Oxidation显示文摘Oxygenation constants and thermodynamic parameters DHo and DSo of cobalt (II) complexes with bis-(furaldehyde) Schiff bases (1, 2, 3, 4)were obtained by mearsuring saturated dioxygen uptake of these complexes in pyridine at different temperature. These complexes could activate molecular oxygen and were used as catalysts in cyclohexene oxidation. The influence of ligand structure on the dioxygen affinity and catalytic activity of the complexes were discussed.Sun, B Chen, JR Hu, JY Li, XJ 2001Chinese Chemical Letters2001,12,11:4
3Hypertrophic adenoids in patients with nasopharyngeal carcinoma:appearance at magnetic resonance imaging before and after treatment显示文摘Introduction:Patients with nasopharyngeal carcinoma(NPC) sporadically develop abnormal adenoids.Nasopharyngeal adenoids are usually included in the gross tumor volume(GTV) but may have different therapeutic responses than tumor tissue.Therefore,distinguishing adenoids from tumor tissue may be required for precise and efficient chemoradiotherapy and radiotherapy.We characterized nasopharyngeal adenoids and investigated the therapeutic responses of NPC and nasopharyngeal adenoids using magnetic resonance imaging(MRI).Methods:MRI data from 40 NPC patients with a coexisting adenoid mass before and after treatment were analyzed.The features of the adenoid masses,including location,striped appearance,size,interface,symmetry/asymmetry,and cysts,were evaluated.Treatment response were scored according to the World Health Organization guidelines.Results:A striped appearance was observed in 36 cases before treatment and in all cases after treatment.In these 36 cases,the average GTVs including and excluding the uninvolved adenoids were 19.8 cm^3 and 14.8 cm^3,respectively.The average percentage change after excluding the uninvolved adenoids from the GTV was 31.0%.Stable disease in the adenoids was identified in 27(96.4%) of 28 patients after neoadjuvant chemotherapy,while NPC clearly regressed.Partial adenoid responses were identified in 33(82.5%) of 40 patients at 3 months after chemoradiotherapy or radiotherapy,whereas complete tumor responses were achieved in all patients.Six months after treatment,the adenoids continued to atrophy but did not disappear,and tumor recurrence was not found.Conclusions:Nasopharyngeal adenoids and carcinoma tissue in NPC patients can be distinguished by using MRI and have different responses to chemoradiotherapy and radiotherapy.These findings contribute to better delineating the GTV of NPC,based on which spatially optimized strategies can be developed to render precise and efficient chemoradiotherapy and radiotherapy.Additionally,we observed a clear difference in the responses of these two tissue types to current therapies.This finding may reduce or avoid unnecessary biopsies or overtreatment.Yao-Pan Wu Pei-Qiang Cai Li Tian Jie-Hua Xu Richard Alan Mitteer Jr Yi Fan Zhenfeng Zhang 2015Chinese Journal of Cancer2015,34,3:4

5PM_(2.5)and water-soluble inorganic ion concentrations decreased faster in urban than rural areas in China显示文摘We investigated variations of PM_(2.5)and water-soluble inorganic ions chemical characteristics at nine urban and rural sites in China using ground-based observations.From 2015 to 2019,mean PM_(2.5)concentration across all sites decreased by 41.9μg/m~3with a decline of 46%at urban sites and 28%at rural sites,where secondary inorganic aerosol(SIAs)contributed to 21%(urban sites)and 17%(rural sites)of the decreased PM_(2.5).SIAs concentrations underwent a decline at urban locations,while sulfate(SO_(4)^(2–)),nitrate(NO_(3)^(–)),and ammonium(NH_(4)^(+))decreased by 49.5%,31.3%and 31.6%,respectively.However,only SO_(4)^(2–)decreased at rural sites,NO_(3)^(–)increased by 21%and NH_(4)^(+)decreased slightly.Those changes contributed to an overall SIAs increase in 2019.Higher molar ratios of NO_(3)^(–)to SO_(4)^(2–)and NH_(4)^(+)to SO_(4)^(2–)were observed at urban sites than rural sites,being highest in the heavily polluted days.Mean molar ratios of NH_(3)/NH_xwere higher in 2019 than 2015 at both urban and rural sites,implying increasing NH_xremained as free NH_(3).Our observations indicated a slower transition from sulfate-driven to nitrate-driven aerosol pollution and less efficient control of NO_(x)than SO_(2)related aerosol formation in rural regions than urban regions.Moreover,the common factor at urban and rural sites appears to be a combination of lower SO_(4)^(2–)levels and an increasing fraction of NO_(3)^(–)to PM_(2.5)under NH_(4)^(+)-rich conditions.Our findings imply that synchronous reduction in NO_(x)and NH_(3)emissions especially rural areas would be effective to mitigate NO_(3)^(–)-driven aerosol pollution.Yangyang Zhang Aohan Tang Chen Wang Xin Ma Yunzhe Li Wen Xu Xiaoping Xia Aihua Zheng Wenqing Li Zengguo Fang Xiufen Zhao Xianlong Peng Yuping Zhang Jian Han Lijuan Zhang Jeffrey L.Collett Jr Xuejun Liu 2022Journal of Environmental Sciences2022,34,12:2
