| 1 | Rapid control of black and odorous substances from heavilypolluted sediment by oxidation:Efficiency and effects显示文摘The control ofblack and odorous substances in sediments is of crucial importance to improve the urban ecological landscape and to restore water environments accordingly.In this study,chemical oxidation by the oxidants NaClO,H2O2,and KMnO4 was proposed to achieve rapid control of black and odorous substances in heavily-polluted sediments.Results indicate that NaClO and KMnO4 are effective at removing Fe(II)and acid volatile sulfides.The removal efficiencies of Fe(II)and AVS were determined to be 45.2%,94.1%,and 93.7%,89.5%after 24-h exposure to NaClO and KMnO4 at 0.2 mmol/g,respectively.Additionally,rapid oxidation might accelerate the release of pollutants from sediment.The release of organic matters and phosphorus with the maximum ratios of 22.1%and 51.2%was observed upon NaClO oxidation at 0.4 mmol/g.Moreover,the introduction of oxidants contributed to changes in the microbial community composition in sediment.After oxidation by NaClO and KMnO4 at 0.4 mmol/g,the Shannon index decreased from 6.72 to 5.19 and 4.95,whereas the OTU numbers decreased from 2904 to 1677 and 1553,respectively.Comparatively,H2O2 showed a lower effect on the removal of black and odorous substances,pollutant release,and changes in sediment microorganisms.This study illustrates the effects of oxidant addition on the characteristics of heavily polluted sediments and shows that chemical oxidants may be an option to achieve rapid control of black and odorous substances prior to remediation of water environments. | Kun Li Min Yang Jianfeng Peng Ruiping Liu Tista Prasai Joshi Yaohui Bai Huijuan Liu | 2019 | Frontiers of Environmental Science & Engineering2019，13，6： | 3 |

| 3 | Adipose-derived stem cells improve grafted burn wound healing by promoting wound bed blood flow显示文摘Background:Researchers have explored the use of adipose-derived stem cells(ASCs)as a cellbased therapy to cover wounds in burn patients;however,underlying mechanistic aspects are not completely understood.We hypothesized that ASCs would improve post-burn wound healing after eschar excision and grafting by increasing wound blood flow via induction of angiogenesis-related pathways.Methods:To test the hypothesis,we used an ovine burn model.A 5 cm^(2) full thickness burn wound was induced on each side of the dorsum.After 24 hours,the burned skin was excised and a 2 cm^(2) patch of autologous donor skin was grafted.The wound sites were randomly allocated to either topical application of 7 million allogeneic ASCs or placebo treatment(phosphate-buffered saline[PBS]).Effects of ASCs culture media was also compared to those of PBS.Wound healing was assessed at one and two weeks following the application of ASCs.Allogeneic ASCs were isolated,cultured and characterized from non-injured healthy sheep.The identity of the ASCs was confirmed by flow cytometry analysis,differentiation into multiple lineages and gene expression via real-time polymerase chain reaction.Wound blood flow,epithelialization,graft size and take and the expression of vascular endothelial growth factor(VEGF)were determined via enzyme-linked immunosorbent assay and Western blot.Results:Treatment with ASCs accelerated the patch graft growth compared to the control(p<0.05).Topical application of ASCs significantly increased wound blood flow(p<0.05).Expression of VEGF was significantly higher in the wounds treated with ASCs compared to control(p<0.05).Conclusions:ASCs accelerated grafted skin growth possibly by increasing the blood flow via angiogenesis induced by a VEGF-dependent pathway. | Osamu Fujiwara Anesh Prasai Dannelys Perez-Bello Amina El Ayadi Irene Y.Petrov Rinat O.Esenaliev Yuriy Petrov David N.Herndon Celeste C.Finnerty Donald S.Prough Perenlei Enkhbaatar | 2020 | Burns & Trauma2020，8，1： | 1 |
