1江南造山带雪峰隆起区元古宙浊积岩沉积构造背景的地球化学制约显示文摘江南造山带雪峰隆起区元古宙浊积岩的地球化学组成良好地反映了沉积盆地的板块构造性质,并为解释区域大地构造的性质和演化提供了有用的信息。中元古代冷家溪群和新元古代板溪群(包括下部马底驿组和上部五强溪组)地层在主元素成分上无明显区别,总体上以中等SiO2含量和K2O/Na2O比值以及较高的(Fe2O3+MgO)含量为特征。稀土元素球粒陨石标准化曲线与典型的后太古宙页岩(如PAAS或NASC)和上陆壳相似,以轻稀土富集、显著的铕负异常和重稀土平坦为特征。大离子亲石元素和铁镁族元素的含量中等。主元素和微量元素特征指示了研究区元古宙浊积岩很可能代表了一套活动大陆边缘弧后沉积盆地的产物。陆内裂谷盆地模式对于解释新元古代华南地区的构造性质和演化可能并不合适。华夏陆块与扬子陆块的拼接以及Rodinia超大陆的最终形成可能发生在约0.8Ga左右的晋宁(雪峰)造山运动期,而不是全球Grenville造山期末的四堡(东安)运动期。顾雪祥 刘建明 Oskar Schulz Franz Vavtar 郑明华 2003地球化学2003,32,5:53
2湖南沃溪钨锑金建造矿床同生成因的微量元素和硫同位素证据显示文摘对岩矿石和矿物的微量元素、稀土元素和硫同位素地球化学的研究表明 ,湖南沃溪钨 锑 金建造矿床系海底同生热水沉积作用的产物。矿石与围岩中微量元素和稀土元素含量的变化关系 ,反映了一种复杂的热液、海水以及陆源碎屑的联合影响。矿石及其中矿物 (石英 )的稀土元素配分模式可与许多沉积喷流型 (sedex型 )块状硫化物矿石及其共生的喷流岩相对比 ,暗示了两者具有相似的形成机理。矿石的硫同位素资料显示 ,生物成因硫与热液成因硫 (下伏沉积柱中硫化物的溶解和 /或部分海水硫酸盐的还原 )顾雪祥 刘建明 Oskar Schulz Franz Vavtar 郑明华 2004地质科学2004,39,3:29
3湖南沃溪金-锑-钨矿床成因的稀土元素地球化学证据显示文摘沃溪金-锑-钨矿床的稀土元素地球化学组成良好地反映了成矿作用的条件和过程,并为示踪矿床成因提供了有用的信息。以流体包裹体为代表的成矿溶液,以较高的稀土总量、显著的轻稀土富集和缺乏明显的铕异常为特征,代表了一种通过在碎屑沉积物柱中循环而萃取矿质的演化的海水热液。矿石相对于成矿流体(母液)富集重稀土而轻微亏损铕,反映了矿石沉淀过程中来自于海水的稀土元素掺合。同一矿层内由下往上,重稀土相对富集的程度逐渐增大而稀土总量则逐渐降低,表明随着热液化学沉淀作用的进行,海水掺合的影响逐渐增强。矿石的稀土元素组成,无论在分布模式还是在轻重稀土之间的分馏程度上,均与其他许多Sedex型多金属矿床十分相似,暗示了这些矿床具有相似的成因机制。稀土元素地球化学特征支持矿床同生沉积成因的观点。顾雪祥 刘建明 Oskar Schulz Franz Vavtar 付绍洪 2005地球化学2005,34,5:30

5湖南沃溪W-Sb-Au矿床成因的流体包裹体证据显示文摘系统研究了沃溪W-Sb-Au矿床层状矿体的流体包裹体特征,均一温度集中在120~180℃,盐度变化于2.9%~8.9%NaCl之间,由包裹体均一温度与盐度计算得出的流体密度介于0.94~0.96g/cm^3。流体包裹体稀土元素地球化学组成表明,成矿流体为一种进化的海水,即海水在海底下沉积柱循环过程中萃取矿质,形成120~180℃温度的低密度成矿流体。当其回返上升到海底后,形成悬浮热液柱,并与冷海水逐渐掺和,发生化学和机械-化学沉积,在海底形成层状矿体。流体包裹体均一温度和盐度的变化范围与很多沉积喷流(SEDEX)矿床极为相似,暗示与这些矿床具有相似的成因机制。同一矿层、条带状矿石中同一条带的石英中包裹体均一温度和盐度的规律性变化,支持沃溪W-Sb-Au矿床的同生热水沉积成因观点。董树义 顾雪祥 Oskar Schulz Franz Vavtar 刘建明 郑明华 程文斌 2008地质学报2008,82,5:16
6Anti-inflammatory effects of bifidobacteria by inhibition of LPS-induced NF-κB activation显示文摘AIM: Different strains of bifidobacteria were analysed for their effects on HT-29 intestinal epithelial cells (IECs) in in vitro models both of the non-inflamed and inflamed intestinal epithelium. METHODS: A reporter gene system in HT-29 cells was used to measure levels of NF-KB activation after challenge with bifidobacteria or after bacterial pre-treatment following LPS challenge. IL-8 protein and pro-inflammatory gene expression was investigated using normal HT-29 cells. RESULTS: None of the bifidobacteria tested induced activation of nuclear factor KB (NF-KB) indicating that bifidobacteria themselves do not induce inflammatory events in IECs. However, six out of eight bifidobacteria tested inhibited lipopolysaccharide- (LPS-) induced NFKB activation in a dose- and strain-dependent manner. In contrast, NF-KB activation in response to challenge with tumor necrosis factor-α(TNF-α) was affected by none of the tested bifidobacteria, indicating that the inhibitory effect of bifidobacteria is specific for LPS-induced inflammation in IECs. As shown with two of the six inhibitionpositive bifidobacteria, LPS-induced inhibition of NFKB activation was accompanied by a dose-dependent decrease of interleukin 8 (IL-8) secretion and by lower mRNA levels for IL-8, TNF-a, cyclooxygenase 2 (Cox-2), and intercellular adhesion molecule 1 (ICAM-1). CONCLUSION: Some strains of bifidobacteria are effective in inhibiting LPS-induced inflammation and thus might be appropriate candidates for probiotic intervention in chronic intestinal inflammation.Christian U Riedel Francis Foata David Philippe Oskar Adolfsson Bernhard J Eikmanns Stephanie Blum 2006World Journal of Gastroenterology2006,12,23:14
7Bifidobacterium lactis attenuates onset of inflammation in a murine model of colitis显示文摘AIM: To assess the anti-inflammatory effect of the probiotic Bifidobacterium lactis (B. lactis) in an adoptive transfer model of colitis. METHODS: Donor and recipient mice received either B. lactis or bacterial culture medium as control (deMan Rogosa Sharpe) in drinking water for one week prior to transfer of a mix of naive and regulatory T cells until sacrifice. RESULTS: All recipient mice developed signs of colonic inflammation, but a significant reduction of weight loss was observed in B. lactis-fed recipient mice compared to control mice. Moreover, a trend toward a diminution of mucosal thickness and attenuated epithelial damage was revealed. Colonic expression of pro-inflammatory and T cell markers was significantly reduced in B. lactis-fed recipient mice compared to controls. Concomitantly, forkhead box protein 3, a marker of regulatory T cells, was significantly up-regulated by B. lactis. CONCLUSION: Daily oral administration of B. lactis was able to reduce inflammatory and T cells mediators and to promote regulatory T cells specific markers in a mouse model of colitis.David Philippe Laurent Favre Francis Foata Oskar Adolfsson Genevieve Perruisseau-Carrier Karine Vidal Gloria Reuteler Johanna Dayer-Schneider Christoph Mueller Stéphanie Blum 2011World Journal of Gastroenterology2011,17,4:12

9Radioprotective thermally generated free-radical dextrins显示文摘Effect of doses of the X-ray radiation from 0 to 400 Gy upon granular cornstarch and dextrins (British gums, BG) thermally generated from it at 230-300℃ was recognized with quantitative EPR and IR ab-sorption spectroscopy, molecular mass distribution in the depolymerization products, Scanning Elec-tron Microscopy, and X-ray diffractometry. Fractal analysis of the profiles of molecular mass distribu-tion showed that the depolymerization involved debranching of amylopectin. Roasting of cornstarch produced BG which differed in concentration and EPR parameters of stable free radicals from BG generated by X-ray radiation. Two types of stable free radicals, with Gaussian and Lorentzian shapes of EPR signals, were recognized. The shapes of the signals and temperature dependence on free radical intensity indicated exchanging interactions of the antiferromagnetic type, causing partial quenching of the spins at-196℃ (77K). Upon X-ray irradiation, new radicals were generated, the number and stability of which strongly depended on the types of radicals present before irradiation. These radicals slowly ceased because of a repolymerization of BG on storage.Piotr TOMASIK Oskar MICHALSKI Ewa BIDZINSKA Antonina CEBULSKA-WASILEWSKA Krystyna DYREK Maciej FIEDOROWICZ Pawe OLKO 2008Chinese Science Bulletin2008,53,7:3

11Novel Mycelium-Based Biocomposites (MBB) as Building Materials显示文摘Novel mycelium-based biocomposites(MBB)were obtained from local agricultural(hemp shives)and forestry(wood chips)by-products which were bounded together with natural growth of fungal mycelium.As a result,hemp mycocomposites(HMC)and wood mycocomposites(WMC)were manufactured.Mechanical,water absorption and biodegradation properties of MBB were investigated.MBB were characterized also by ash content and elemental composition.The results of MBB were compared with the reference materials such as the commercial MBB material manufactured by Ecovative®Design(EV),hemp magnesium oxychloride concrete(HC)and cemented wood wool panel(CW),manufactured by CEWOOD®.The mechanical properties of HMC and WMC showed that the bending strength difference was about 30%,with a better result for HMC.Compression strength was better for WMC by about 60%compared to that of HMC.The mechanical strength of HMC and HC materials was equal;both materials contained hemp shives but differed by the binding material.Water absorption and volumetric swelling tests showed that HMC and WMC could be considered as potential biosorbents.Ash content and elemental analysis showed that reference materials(CW,HC)contained significant amounts of inorganic compounds that decreased the biodegradation rate,compared to the case of HMC and WMC materials.The biodegradation results of HMC and WMC,after 12 weeks,revealed a mass loss(ML)above 70%,while in the case of EV,HC and CW,it was about 60%,17%and only 6%,respectively.MBB were completely biodegradable.Zinta Zimele Ilze Irbe Juris Grinins Oskars Bikovens Anrijs Verovkins Diana Bajare 2020Journal of Renewable Materials2020,8,9:2

15雨养沼泽泥炭腐植酸的性质和结构显示文摘腐植酸类物质是土壤、泥炭和自然水体中有机物的主要成分,其来源不同,结构和性质也不同。本研究阐述了雨养沼泽泥炭腐植酸的性质,评估了泥炭剖面内腐植酸的均质性,并研究了泥炭腐殖化程度对腐植酸性能的影响。结果表明,以不同来源的苔藓为主的雨养沼泽植物对泥炭腐植酸结构的影响较大。泥炭腐植酸的成岩作用程度介于活有机体和煤炭之间,当碳水化合物、氨基酸等被破坏后,耐分解的芳烃和多环芳烃结构出现,泥炭腐植酸的结构趋于形成。然而,与土壤、水体和其他腐植酸相比,泥炭腐植酸的芳香性较低。相对而言,雨养沼泽泥炭腐植酸处于活有机体向成岩转化过程的初始阶段。羧基和酚羟基含量的变化取决于提取腐植酸的泥炭年龄和分解程度,羧酸酸度随泥炭深度和腐殖化程度增加而增大。Maris Klavins Oskars Purmalis 韩征 赵红艳 2014腐植酸2014,,4:2
16Fulminant liver failure following a marathon: Five case reports and review of literature显示文摘BACKGROUND The growing popularity of marathon and half-marathon runs has led to an increased number of patients presenting with exertion-induced heat stroke. Mild hepatic involvement is often observed in these patients;however, fulminant liver failure may occur in approximately 5% of all cases. Liver transplantation is a potentially curative approach for exertion-induced liver failure, although there is a lack of consensus regarding the criteria and optimal timing of this intervention. CASE SUMMARY This paper describes 5 patients (4 men and 1 woman) who were referred to the department where this study was performed with the diagnosis of exertioninduced acute liver failure. Three patients underwent liver transplantation, 1 recovered spontaneously, and 1 patient died on day 11 following the exertion. CONCLUSION Exertion-induced heat stroke may present as fulminant liver failure. These patients may recover with conservative treatment, may require liver transplantation, or may die. No definitive criteria are available to determine patient suitability for a conservative vs surgical approach.Wojciech Figiel Marcin Morawski Michal Grat Oskar Kornasiewicz Grzegorz Niewiński Joanna Raszeja-Wyszomirska Maciej Krasnodebski Arkadiusz Kowalczyk Waclaw Holówko Waldemar Patkowski Krzysztof Zieniewicz 2019World Journal of Clinical Cases2019,7,12:2

20Fatigue is not associated with vitamin D deficiency in inflammatory bowel disease patients显示文摘AIM To investigate if vitamin D deficiency is associated with fatigue in patients with inflammatory bowel disease(IBD).METHODS IBD patients were recruited from nine hospitals in the southeastern and western regions of Norway to participate in a multicenter cross-sectional study lasting from March 2013 to April 2014. Data were collected by interviews, from medical records and laboratory tests. The Fatigue Questionnaire(FQ) was used to measure fatigue. Linear and logistic regression models were applied to explore the possible association between vitamin D deficiency and total fatigue scores and chronic fatigue, respectively. The analyses were adjusted for age, gender, disease activity, depressive symptoms and sleep disturbance.RESULTS In total, 405 patients were included in the analyses, of which 227(56%) had Crohn's disease(CD) and 178(44%) had ulcerative colitis(UC). Vitamin D deficiency(< 50 nmol/L) was present in half(203/405) of the patients. Chronic fatigue was reported by 116(29%) of all included patients with substantial fatigue reported by 194(48%). Vitamin D levels were neither associated with total fatigue nor with chronic fatigue. Higher total fatigue scores and chronic fatigue were both associated with increased disease activity scores in patients with UC and CD, but not with increased CRP or fecal calprotectin. In UC patients, female gender was associated with fatigue in the univariate analysis, but no such difference was found when adjusted for elevated disease activity scores. Sleep disturbance and more depressive symptoms were associated with total fatigue scores in both UC and CD patients, but with chronic fatigue only in CD patients.CONCLUSION In this study, no significant association between fatigue and vitamin D deficiency in IBD patients was revealed.Svein Oskar Frigstad Marte Lie Hoivik Jorgen Jahnsen Milada Cvancarova Tore Grimstad Ingrid Prytz Berset Gert Huppertz-Hauss Oistein Hovde Tomm Bernklev Bjorn Moum Lars-Petter Jelsness-Jorgensen 2018World Journal of Gastroenterology2018,24,29:2
