| 1 | 美国病理住院医师培训制度显示文摘鉴于国内病理医师培养的现状,在本文中拟介绍美国病理住院医师培训制度,以供国内同仁参考、借鉴。
病理学研究疾病的机制、形态和分子改变,是临床与基础学科间的桥梁学科。其专业范围涉及疾病诊断、医学教育和基础研究。病理学涵盖解剖病理、细胞病理、内、外、妇、儿、眼、耳鼻咽喉、口腔、皮肤、尸检解剖和法医学等病理专科及其众多相关学科,如细胞化学、细胞学和遗传学、流行病学、影像诊断学、医学文献与数据库、实验室管理等。 | 程亮 张绍渤 Fred G.Silva | 2008 | 中华病理学杂志2008，37，9： | 8 |

| 3 | Polymeric Nanomaterials as Electrolyte and Electrodes in Supercapacitors显示文摘The energy challenge requires a broad range of options for energy harvesting,storage,and conversion.We have produced polymeric coatings by spraying,to be used as electrolyte and electrodes in a fl exible electrochemical double layer capacitor.A thermoplastic polyurethane and a low molecular weight block copolyether were employed with LiClO_(4) to prepare solid polymeric electrolytes.Carbon black(CB)and multi-walled carbon nanotubes(MWNTs)were dispersed in the polymer blend electrolyte to produce nanostructured composite electrodes.The conductivities increased with the addition of block copolyether and carbon nanotubes to the electrolyte and electrode,respectively.Scanning electron microscopy(SEM)and atomic force microscope(AFM)images of the nanocomposite electrodes showed nanoagglomerates of CB connected by carbon nanotubes.The solid supercapacitor prepared with these new materials as electrolyte and electrodes showed superior performance to other similar systems.The resulting safe and fl exible multilayer device can meet the requirements of modern devices. | João P.C.Trigueiro Raquel S.Borges Rodrigo L.Lavall Hallen D.R.Calado Glaura G.Silva | 2009 | Nano Research2009，2，9： | 1 |
| 4 | Effects of aeration on the suspended matter from a tropical and eutrophic estuary显示文摘A comprehensive understanding of the complex biogeochemical interactions between organic matter and persistent contaminants in the suspended matter is vital for ecoefficient estuary recovery.However,little is known regarding aeration effects in suspended particulate aggregates.Therefore,this study aimed to investigate the effects of aeration on the suspended matter from a Tropical and Eutrophic estuarine environment.Anoxic water with 60 g/L of suspended particulate matter(SPM)was collected from Guanabara Bay,Rio de Janeiro,Brazil,transferred to experimental boxes and aerated for 61 days.SPM aggregates monitoring included abiotic variables measurements and,determination of total organic matter(TOM),biopolymers composition,bacterial activity,trace metals,and polycyclic aromatic hydrocarbons(PAHs)concentrations.The aeration enhanced dissolved oxygen(DO)concentration and the redox potential(Eh).However,from days 0 to 61 the predominant bacterial activities were denitrification and fermentation.Electron transport system activity increased after day 10,and aerobic activity was detected after day 19.In summary,aeration increased aerobic bacterial activity,lipids(LIP)and trace metal concentrations,although diminished protein/carbohydrate ratio and PAH concentration.Trace metals concentration(Ni,Pb,Cu,Cr,Mn,and Fe)were the highest on day 19 when the p H was 5.9.Copper presented toxic values(Cu>20.0μg/g).The p H showed a strong negative correlation with Eh(r=-0.94;p<0.001).Acidic environment(p H≤5.9)in marine ecosystems with high loads of toxic trace metals is unsafe for biota.Therefore,managers must be aware of the environmental and biological risks of introducing the aeration technique into a eutrophic marine environment. | Natascha Krepsky Maria das Gracas S.Bispo Luiz F.Fontana Frederico S.da Silva Jodo P.M.Torres Olaf Malm Cleverson G.Silva Mirian A.C.Crapez | 2019 | Journal of Environmental Sciences2019，31，12： | 0 |
| 5 | Lectin from Crataeva tapia bark exerts antitumor,anti-inflammtory and analgesic activities显示文摘Crataeva tapia bark lectin was evaluated for its antitumor activity against sarcoma 180 in Swiss albino mice.The anti-inflammatory and analgesic properties were investigated in models of inflammation and nociception.The anti-inflammatory assay was induced by carrageenan induced peritonitis and the analgesic activity was induced by acetic acid-induced writhing response.The lectin presents low toxicity with a LD50 of 2,500 mg/kg body weight and significant antitumor activity causing inhibition of tumor growth.The lectin also promoted significant reduction(35.4%)in the number of neutrophil migration induced by carrageenan.Concerning its analgesic property,the lectin inhibits abdominal contractions induced by acetic acid.The current results revealed a lectin with significant antitumoral,anti-inflammatory and antinociceptive activities.Further investigations to unveil the exact mechanisms are needed. | Regina M.S.ARAÚJO Antônio F.M.VAZ Jaciana S.AGUIAR Luana C.B.B.COELHO Patrícia M.G.PAIVA Ana M.M.MELO Teresinha G.SILVA Maria T.S.CORREIA | 2011 | Natural Products and Bioprospecting2011，1，2： | 0 |
| 6 | 7075铝合金的淬火敏感性(英文)显示文摘7075铝合金广泛用于要求高力学性能的零部件。有关技术文献指出,该合金的耐蚀性和力学性能主要决定于淬火冷却速度。这种现象通常称为'淬火敏感性'。本文的主要目的是,通过改变热处理工艺参数和轧制方向(L,LT,ST)来研究板材试样的淬火冷却速度对其性能的影响。试样均在实验室设备中热处理,以获得T6、T76和T73处理状态。试样为长方体(13 mm×13 mm×100 mm),水淬,通过改变水温或改变温度为20℃、用水搅动的浴槽中聚合物浓度来调节淬火冷却速度。在每种实验条件下,均采用置于试样中的热电偶测量冷却速度。此外,还进行了有限元(FEM)模拟试验,以测定所有试验条件下冷却过程的热传递系数;进行了拉伸试验和晶间腐蚀试验,以弄清所研究的冷却速度对7075合金板材性能的影响。 | B.Rivolta G.Silva R.Gerosa | 2010 | 热处理2010，25，5： | 0 |
