Influence of combustion-originated dioxins in atmospheric deposition on water quality of an urban river in Japan

引用

Journal of Environmental Sciences 2018年第2期30卷 245-251页

作者： Kotaro Minomo Nobutoshi Ohtsuka Kiyoshi Nojiri rie Matsumoto Center for Environmental Science in Saitama Kazo Saitama 347-0115 Japan

Bulk（wet and dry） deposition samples were collected in Saitama Prefecture, Japan throughout a year（February 8, 2012 to February 7, 2013） to estimate the influence of dioxins emitting from waste incinerators on river water quality. The annual deposition flux of dioxins was 3.3 ng-toxic equivalent（TEQ）/m^2/year. Source identification using indicative congeners estimated that 82% of dioxin TEQ in the bulk deposition（2.7 ng-TEQ/m^2/year）was combustion-originated, indicating that most of the dioxins in the deposition were derived from waste incinerators. In Saitama prefecture the annual flux of combustionoriginated dioxins in depositions was apparently consistent with that of dioxin emission into the air from waste incinerators. The TEQ of combustion-originated dioxins in the deposition per rainfall was 2.4 pg-TEQ/L on annual average, exceeding the environmental quality standard（EQS） for water in Japan of 1 pg-TEQ/L. This suggests there is a possibility that dioxins in atmospheric deposition have a significant influence on the water quality of urban rivers which rainwater directly flows into because of many paved areas in the *** influence of combustion-originated dioxin in the deposition on the water quality of Ayase River, an urban river heavily polluted with dioxins, was estimated at 0.29 pg-TEQ/L on annual average in 2015. It seems that dioxins in atmospheric deposition from waste incinerators have a significant influence on water quality of some urban rivers via rainwater though the dioxins in the ambient air have achieved the EQS for atmosphere at all monitoring sites in Japan.

Maintenance of radiation-induced intestinal fibrosis:Cellular and molecular features

引用

World Journal of Gastroenterology 2007年第19期13卷 2675-2683页

Recent advances in cell and molecular radiobiology clearly showed that tissue response to radiation injury cannot be restricted to a simple cell-killing process, but depends upon continuous and integrated pathogenic processes, involving cell differentiation and crosstalk between the various cellular components of the tissue within the extracellular matrix. Thus, the prior concept of primary cell target in which a single-cell type （whatever it＇s epithelial or endothelial cells） dictates the whole tissue response to radiation injury has to be replaced by the occurrence of coordinated multicellular response that may either lead to tissue recovery or to sequel development. In this context, the present review will focus on the maintenance of the radiation-induced wound healing and fibrogenic signals triggered by and through the microenvironment toward the mesenchymal cell compartment, and will highlight how sequential and sustained modifications in cell phenotypes will in cascade modify ceU-to-ceU interactions and tissue composition.

Ecological speciation in Darwin＇s finches： Parsing the effects of magic traits

引用

Current Zoology 2013年第1期59卷 8-19页

作者： Jeffrey PODOS rie DYBBOE Mads Ole JENSEN Department of Biology University of Massachusetts Amherst MA 01003 USA Department of Biology University of Copenhagen The August Krogh Bldg. Universitetsparken 13 DK-2100 CopenhagenDenmark Horsens Statsskole Studenterwenget 2 7000 Horsens Denmark

Many recent studies of ecological speciation have focused on ＂magic trait＂ scenarios, in which divergent selection on viability traits leads inextricably to corresponding divergence in mechanisms, especially mate recognition systems, that facilitate assortative mating. Speciation however may also proceed via other scenarios, such as when populations experience directly se- lected or random divergence in mate recognition systems. The relative contributions of magic trait versus other scenarios for speciation remain virtually unexplored. The present study aims to test the relative contribution of the magic trait scenario in the divergence of populations of the medium ground finch Geospiza fortis of Santa Cruz Island, Galapagos. First, we assess differ- ences in G. fortis song between a northern population （Borrero Bay） and a southeastern population （El Garrapatero）, differences that we propose （along with other within-island geographic song variations） have arisen via scenarios that do not involve a magic trait scenario. Pairwise comparisons of raw and composite （PC） song parameters, as well as discriminant functions analyses, re- veal significant patterns of song divergence between sites. Second, we test the ability of territorial males at Borrero Bay to dis- criminate songs from the two sites. We find that G. fortis males can discriminate within-island song variants, responding more strongly to local than to ＂foreign＂ songs, along 3 raw and 1 composite response measures. Third, we compare these findings to prior data sets on song divergence and discrimination in Santa Cruz G. fortis. These comparisons suggest that song divergence and discrimination are shaped less strongly by geographic sources than by morphological （beak-related） sources. We thus argue that interpopulation song divergence and discrimination, fundamental elements of assortative mating in Darwin＇s finches, can be fos- tered in early stages of divergence under magic trait as well as alternative scenar

BACKGROUND: Some patients with colorectal carcinoma have liver metastases(LMs) which cannot be detected by conventional imaging. This study aimed to assess whether hepatic perfusion changes induced by micrometastases can be detected by perfusion computed tomography(CT).METHODS: LMs were produced in rats by injecting carcinoma cells into the portal vein. Perfusion CT was performed at microscopic(day 10), interval(day 17), and macroscopic stage(day 34). Perfusion parameters were computed using a dualinput one-compartmental ***: Micro and macro LMs presented a mean diameter of 0.5 and 2.6 mm, respectively. Compared to controls, LMs at interval(1.1 mm) and macroscopic stage induced significant perfusion changes: a decrease of 42%(P=0.004) and 41%(P=0.029) in hepatic transit time and an increase of 292%(P=0.073) and 240%(P=0.001) in portal delay, ***: LMs with a mean diameter between 1.1 and2.6 mm induced significant hepatic perfusion changes, detected by CT. Such detection may help to select patients and propose chemotherapy at the time of primary tumor resection.
