3贵州遵义牛蹄塘组黑色岩系有机质的稀土元素地球化学研究显示文摘以贵州遵义寒武纪初牛蹄塘组黑色岩系的有机质为分析对象,对22个样品的稀土元素(REE)组成进行了研究,结果表明:①有机质的ΣREE占全岩ΣREE的10%左右,且其REE标准化配分曲线不同于全岩的。由于有机质主要来自海洋上层水体中的微生物,因而可以认为其REE特征代表的是古海洋上层水体的稀土元素组成特征;②有机质的REE总量变化于11.6×10&-6-548×10&-6之间,Ce异常系数变化于0.40-0.92之间,Eu异常系数变化于0.59-1.14之间。有机质的Ce异常系数和LaN/CeN值在剖面上显示明显的变化,指示研究区经历了大陆斜坡到大洋盆地再到大陆边缘的环境,指示在寒武纪初存在一次海侵。皮道会 刘丛强 邓海琳 Graham Shields 2008矿物学报2008,28,3:13
4Cyclooxygenase-2 plays a central role in the genesis of pancreatitis and associated lung injury显示文摘BACKGROUND: The exact mechanism by which cyclooxy- genase-2 (COX-2) promotes inflammation in pancreatitis in obscure. This study was undertaken to investigate the role of COX-2 inhibition in an animal model of pancreati- tis , a disease process characterized by a systemic inflamma- tory response and ensuing neutrophil-mediated lung injury. METHODS: Pancreatitis was induced in 24 Sprague-Daw- ley rats by intraperitoneal injection of 20% L-arginine (500 mg/100 g body weight). The animals were randomized into 3 groups (8 rats in each group); controls and rats with pancreatitis intravenously resuscitated with either normal saline (0.9% NaCl 3 ml/kg) at 24 and 48 hours or COX-2 inhibitor (parecoxib 1 mg/kg). Pancreatic and lung inju- ries were assessed histologically. Lung injury was assessed utilizing wet;dry ratio and myeloperoxidase activity to in- dicate pulmonary neutrophil infiltration. A Western blot was used to determine COX-2 protein expression in pancrea- tic tissue. RESULTS: The animals treated with COX-2 inhibitors dis- played significantly less pancreatic and lung injuries than their normal saline counterparts. Histological pancreatic and lung injury scores were significantly reduced (P <0.05) in the COX-2 treated group. Lung wet: dry ratios were sig- nificantly improved and pulmonary neutrophil infiltration was attenuated in the COX-2 group (P<0.05). Western blot analysis confirmed attenuated COX-2 protein expression. CONCLUSION: This study shows, for the first time in a rat model, that adjuvant COX-2 inhibition significandy attenu- ates the severity of both pancreatitis and its associated sys- temic inflammatory response and end-organ injury.Gavin O'Brien Conor J Shields Desmond C Winter John P Dillon 2005Hepatobiliary & Pancreatic Diseases International2005,4,1:12

8SEDIMENT RETENTION AND WATER QUALITY ENHANCEMENT IN DISTURBED WATERSHEDS`显示文摘Globally, water quality and quantity issues are alarming. Water quality problems generally result from past and present large-scale land uses. Continuing deterioration of water quality and use/reuse issues place the responsibility on agriculture for water quality improvement. Research on agricultural management practices in the United States shows that production agriculture can use measures that improve water quality.Instream suspended sediments and bedload are, by volume, the largest category of pollutant, sediments also carry many compounds that adhere to them in transport. Thus, reducing sediments must play a major role in improving water quality. Innovative management practices can reduce sediments and nutrients by 70 percent or more. If broadly applied, agricultural management and stream stabilization practices can significantly reduce non-point source contamination and have the extra benefit of improving terrestrial and aquatic habitat.C.

10Genetic Improvement of Willow for Bioenergy and Biofuels显示文摘Willows (Salix spp.) are a very diverse group of catkin-bearing trees and shrubs that are widely distributed across temperate regions of the globe.Some species respond well to being grown in short rotation coppice (SRC) cycles,which are much shorter than conventional forestry.Coppicing reinvigorates growth and the biomass rapidly accumulated can be used as a source of renewable carbon for bioenergy and biofuels.As SRC willows re-distribute nutrients during the perennial cycle they require only minimal nitrogen fertilizer for growth.This results in fuel chains with potentially high greenhouse gas reductions.To exploit their potential for renewable energy,willows need to be kept free of pests and diseases and yields need to be improved without significantly increasing the requirements for fertilizers and water.The biomass composition needs to be optimized for different end-uses.Yields also need to be sustainable on land less productive for food crops to reduce conflicts over land use.Advances in understanding the physiology and growth of willow,and in the identification of genes underlying key traits,are now at the stage where they can start to be used in breeding programs to help achieve these goals.Angela Karp Steve J.Hanley Sviatlana O.Trybush William Macalpine Ian Shield 2011Journal of Integrative Plant Biology2011,53,2:5

20Lacrimal gland tumors in Turkey:types,frequency,and outcomes显示文摘AIM: To evaluate the clinical, radiological, and treatment features of lacrimal gland tumors.METHODS: Retrospective review of 99 eyes of 92 patients with lacrimal gland tumors diagnosed and managed in a single institution between January 1999 and March 2017. Clinical and radiological features, histopathology, treatment methods, and prognosis were evaluated.RESULTS: The mean patient age was 40.3(range: 7-80)y.The diagnosis was made histopathologically in 91(91.9%) tumors and on a clinical and radiological basis in 8(8.1%) tumors. Final diagnoses included idiopathic orbital inflammation(pseudotumor) in 46(46.5%) lesions, pleomorphic adenoma in 14(14.1%), adenoid cystic carcinoma in 12(12.1%), granulomatous inflammation in 10(10.1%), lymphoma in 5(5.0%), benign reactive lymphoid hyperplasia in 3(3.0%), dacryops in 3(3.0%), carcinoma ex pleomorphic adenoma in 2(2.0%), adenocarcinoma in 1(1.0%), dermoid cyst in 1(1.0%), cavernous hemangioma in 1(1.0%), and leukemic infiltration in 1(1.0%). Nonepithelial tumors comprised 64.6%(n=64) of all lacrimal gland tumors, epithelial tumors 32.3%(n=32), dermoid cyst 1%(n=1), cavernous hemangioma 1%(n=1), and leukemic infiltration 1%(n=1). There were in total 78(78.8%) benign and 21(21.2%) malignant tumors. CONCLUSION: Overall, 65% of lacrimal gland tumors were of non-epithelial origin and 32% of epithelial origin. By histopathology and clinical evaluation, 79% of lacrimal gland tumors were benign. The most common lacrimal gland tumors include idiopathic orbital inflammation(46.5%), epithelial(32.3%), and lymphoproliferative(8.1%) lesions.Yagmur Seda Yesiltas Ahmet Kaan Gundiiz Esra Erden Carol L.
