1Seasonal comparison of moss bag technique against vertical snow samples for monitoring atmospheric pollution显示文摘This is the first study seasonally applying Sphagnum papillosum moss bags and vertical snow samples for monitoring atmospheric pollution.Moss bags,exposed in January,were collected together with snow samples by early March 2012 near the Harjavalta Industrial Park in southwest Finland.Magnetic,chemical,scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDX),K-means clustering,and Tomlinson pollution load index(PLI)data showed parallel spatial trends of pollution dispersal for both materials.Results strengthen previous findings that concentrate and slag handling activities were important(dust)emission sources while the impact from Cu–Ni smelter's pipe remained secondary at closer distances.Statistically significant correlations existed between the variables of snow and moss bags.As a summary,both methods work well for sampling and are efficient pollutant accumulators.Moss bags can be used also in winter conditions and they provide more homogeneous and better controlled sampling method than snow samples.Hanna Salo Anna-Kaisa Berisha Joni M?kinen 2016Journal of Environmental Sciences2016,28,3:3
2漂流海藻垫威胁着芬兰西南部群岛海的海底吗?显示文摘借助水底摄像系统和潜水呼吸器,获得1996~1997年夏季漂流海藻群在波罗的海北部的群岛海(Archipelago Sea)发生情况图。研究范围包括从诲滨到海洋50m的深度范围。按藻群的厚度和是否发生缺氧现象(硫化氢气味,黑色沉淀物),亦即藻群潜在的各种生态学影响,对藻群进行了描述和分类。可以区分出三种不同类型的漂流海藻群:藻盖、藻垫和藻床。对藻群在一个生长季节的演替情况进行了研究。开始,藻类在海底聚集成一薄层;之后,这些薄层海藻开始沿海底坡面向下沉,发展为在一定程度上厌氧的藻垫;最后成为完全厌氧的藻床。在研究区东南角的外群岛海,这种现象把为明显。有利于生活史较短的藻类生长、导致漂流藻垫形成的众多因子包括海水中高营养含量、较好的透明度和适易的基质。研究期间,我们深感水下摄像系统是用来研究水下松散藻群的理想工具:Petri Vahteri Anita Mkinen Sonja Salovius Ilppo Vuorinen 周立志 2000AMBIO-人类环境杂志2000,29,6:2
3Epithelial cell proliferation and glandular atrophy in lymphocytic gastritis: Effect of H pylori treatment显示文摘AIM: Lymphocytic gastritis is commonly ass ociated with Helicobacter pylori infection. The presence of glandular atrophy and foveolar hyperplasia in lymphocytic gastritis suggests abnormalities in cell proliferation and differentiation,forming a potential link with the suspected association with gastric cancer. Our aim was to compare epithelial cell proliferation and morphology in H pylori associated lymphocytic gastritis and H pylori gastritis without features of lymphocytic gastritis,and to evaluate the effect of H pylori treatment.METHODS: We studied 14 lymphocytic gastritis patients with H pylori infection. For controls, we selected 14 matched dyspeptic patients participating in another treatment trial whose H pylori infection had successfully been eradicated.Both groups were treated with a triple therapy and followed up with biopsies for 6-18 months (patients) or 3 months (controls). Blinded evaluation for histopathological features was carried out. To determine the cell proliferation index,the sections were labeled with Ki-67 antibody.RESULTS: Before treatment, lymphocytic gastritis was characterized by foveolar hyperplasia (P=0.001) and glandular atrophy in the body (P=0.008), and increased proliferation in both the body (P=0.001) and antrum (P=0.002). Proliferation correlated with foveolar hyperplasia and inflammation activity. After eradication therapy, the number of intraepithelial lymphocytes decreased in the body (P=0.004)and antrum (P=0.065), remaining higher than in controls (P<0.001). Simultaneously, the proliferation index decreased in the body from 0.38 to 0.15 (P=0.043), and in the antrum from 0.34 to 0.20 (P=0.069), the antral index still being higher in lymphocytic gastritis than in controls (P=0.010).Foveolar hyperplasia and glandular atrophy in the body improved (P=0.021), reaching the non-LG level.CONCLUSION: In lymphocytic gastritis, excessive epithelial cell proliferation is predominantly present in the body, where it associates with foveolar hyperplasia and glandular atrophy.These characteristic changes of lymphocytic gastritis are largely related to H pylori infection, as shown by their improvement after eradication. However, some residual deviation was still seen in lymphocytic gastritis, indicating either an abnormally slow improvement or the presence of some persistent abnormality.Johanna M.Mkinen Seppo Niemel Tuomo Kerola Juhani Lehtola Tuomo J.Karttunen 2003World Journal of Gastroenterology2003,9,12:2
