| 1 | 凋落:Bcl-2是程序性细胞死亡的关键蛋白显示文摘凋落是一种程序性细胞死亡,一种有规律的细胞死亡形式,有别于激发性细胞死亡。程序性细胞死亡的细胞具如下特征:细胞皱缩、染色质凝聚、细胞膜呈典型的外突。在 DNA 水平上,通过 Mg2+/Ca2+相关的核酸内切酶,裂解为180个碱基对大小的若干片断。在无胞浆成分溢出的情况下。 | M.Amling M.Psl I.Bsler G.Delling 阮幼冰 | 1996 | 德国医学1996,13,1: | 6 |

| 10 | 黑人和白化病人眼睑鳞状上皮细胞癌的比较研究(英文)显示文摘目的:比较尼日利亚伊布人中黑人和白化病人眼睑鳞状上皮细胞癌的发病情况。方法:回顾分析过去30a经由组织病理学证明为眼睑鳞状上皮细胞癌的实验室记录。结果:本研究共包括7例患者,其中3例为男性白化病人,年龄由16 ̄39岁;4例男性黑人,年龄由40 ̄60岁。很明显,白化病人眼睑上皮细胞癌的发病年龄较黑人患者要年轻得多。结论:众所周知,眼睑鳞状上皮细胞癌多发生于老年的白人患者,而在尼日利亚白化病人中的发病年龄明显年轻。这一结论有待于世界其他日光照射较强地区的研究进一步证实。 | Wilson I.B .Onuigbo | 2005 | 国际眼科杂志2005,5,5: | 1 |

| 13 | 不锈钢薄带连铸中选择相的形成显示文摘研究了304不锈钢双辊薄带连铸中控制凝固组织的因素,观察到了从铁素体到亚稳态奥氏体最初凝固状态的转变,此转变是由于溶体在冷铸辊附近达到10~3KS^(-1)级相对高的冷速而过冷造成的。原始奥氏体凝固程度取决于不同的熔体装入置之间可能的合金成分的波动,且从临近带钢表面的一些局部奥氏体区到凝固带的完全奥氏体间会产生变化。作为原始铁素体的凝固区,发现了不均匀的Ni,Cr定向偏析,而作为原始奥氏体的凝固区发现了此两元素均匀的定向偏析。磁测量表明:铁素体体积百分数在原始铁素体凝固薄带中变化约为1.3到1.9体积百分数,而凝固为原始奥氏体的试样中,变化量约在0.1到0.2的体积百分数。 | Th.Schubert W.Lser S.Schinnerling I.Bcher 徐炜新 | 1998 | 上海钢研1998,,3: | 1 |

| 18 | Arsenic and sulfur nanoparticle synthesis mimicking environmental conditions of submarine shallow-water hydrothermal vents显示文摘Arsenic and sulfur mineralization is a natural phenomenon occurring in hydrothermal systems where parameters like temperature and organic matter(OM)can influence the mobilization of the toxic metalloid in marine environments.In the present study we analyze the influence of temperature and OM(particularly sulfur-containing additives)on As and S precipitation based on the recent discovery of As-rich nanoparticles in the hydrothermal system near the coast of the Greek island Milos.To this end,we experimentally recreate the formation of amorphous colloidal particles rich in As and S via acidification(pH 3–4)of aqueous precursors at various temperatures.At higher temperatures,we observe the formation of monodisperse particles within the first 24 h of the experiment,generating colloidal particles with diameters close to 160 nm.The S:As ratio and particle size of the synthetized particles closely correlates with values for As_(x)S_(y)particles detected in the hydrothermal system off Milos.Furthermore,organic sulfur containing additives(cysteine and glutathione,GSH)are a key factor in the process of nucleation and growth of amorphous colloidal As_(x)S_(y)particles and,together with the temperature gradient present in shallow hydrothermal vents,dictate the stabilization of As-bearing nanomaterials in the environment.Based on these findings,we present a simple model that summarizes our new insights into the formation and mobility of colloidal As in aquatic ecosystems.In this context,amorphous As_(x)S_(y)particles can present harmful effects to micro-and macro-biota not foreseen in bulk As material. | Vicente Durán-Toro Kurosch Rezwan Solveig I.Bühring Michael Maas | 2022 | Journal of Environmental Sciences2022,34,1: | 0 |
| 19 | 通过自燃机理和影响因素的分析控制煤自燃显示文摘多数煤能自热,这给煤炭开采和贮运带来困难。现实中消除煤的自热是不可能的,不过,若能掌握自燃机理及其影响因素,则可有效地控制煤炭自燃。煤的自燃过程可分6个阶段。其中包括水吸附阶段和5个氧化阶段,即:化学吸附阶段(煤温达70℃),过氧化物分解阶段(煤温在70℃~150℃之间),煤氧复合物生成阶段(煤温在150℃~230℃之间),燃烧初始阶段(煤温达230℃时)和快速燃烧阶段(煤温大于230℃)。以上几个阶段都产生热量。 | I.B达斯 曾强 | 1993 | 陕西煤炭技术1993,,2: | 0 |
| 20 | Plant traits related to leaf decomposition processes in arid ecosystems of northern Patagonia显示文摘Aims Plants play an important role in ecosystem processes.Functional meaning of trait variation in wide environmental gradients is well known but is scarcely known across narrow gradients.We analyze the variation of morphological,physical and chemical traits of dom-inant plant species and the potential rates of dry mass loss and N release/immobilization during senesced leaf decomposition of these species across a narrow aridity gradient,and to identify indicative traits useful to set species functional groups sharing decomposition patterns.Methods We analyzed the variation of morphological,physical and chemical traits(specific leaf area,seed mass,N and soluble phenols in green and senesced leaves,plant height)in dominant plant species at 12 sites across an aridity gradient in northern Patagonia,Argentina.We collected senesced leaves of each plant species at each site and used them to estimate the poten-tial rates of dry mass loss and N release/immobilization from decomposing senesced leaves in a microcosm experiment.We analyzed the variation of plant traits and decomposition rates across the aridity gradient.We grouped plants species accord-ing to growth forms(perennial grasses,deciduous shrubs,ever-green shrubs)and different combinations of morpho-physical and chemical traits of green and senesced leaves and compared the potential rates of dry mass loss and N release/immobiliza-tion during leaf decomposition among these groups delimited by each grouping criteria.Important Findings Plant traits did not vary across the aridity gradient.The potential rate of dry mass loss was positively related to aridity,while the potential rate of N release/immobilization did not vary across the gradient.Grouping species by separately morpho-physical and chemical traits resulted in a large overlapping in mean values of decomposition rates among groups.In contrast,plant groupings based on growth forms and those including all morpho-physical and chemical traits of green or senesced leaves yielded groups with differentiated rates of decomposition processes.The two latter groupings clustered spe-cies from more than one growth form indicating some overlapping in the rates of decomposition processes among species of different growth forms.Among traits,N concentration in senesced leaves and plant height explained the highest variation in decomposition rates being positively related to potential rates of dry mass loss and N release/immobilization.We concluded that plant groupings based on morpho-physical and chemical traits of either green or senesced leaves may be more powerful to differentiate functional species groups sharing decomposition patterns than the growth form group-ing.Moreover,plant height and N concentration in senesced leaves may be considered relevant synthetic functional traits in relation to decomposition processes in narrow aridity gradients. | Marlene I.Bär Lamas Analía L.Carrera Mónica B.Bertiller | 2019 | Journal of Plant Ecology2019,12,2: | 0 |
