2近海沉积物DlPCBs对斑马鱼胚胎EROD和cyp1a mRNA的影响显示文摘为探究湛江近海域海洋沉积物中类二噁英多氯联苯(dioxin-like polychlorinated biphenyls,Dl PCBs)的生物学毒性效应,选取湛江近海域2个地点(近工业区TS和近生活区JSW)采集沉积物样品,制备近海域沉积物Dl PCBs提取物,将斑马鱼胚胎暴露于不同浓度的Dl PCBs提取物,测定斑马鱼胚胎7-乙氧基异吩恶唑脱乙基酶(ethoxyresorufin-O-deethylase,EROD)活性和cyp1a m RNA相对表达量。结果发现,JSW采样点Dl PCBs提取物染毒组EROD酶活性变化与TS采样点Dl PCBs提取物一致,在各染毒浓度下,斑马鱼仔鱼EROD酶活性为对照组的1.1~1.8倍。TS和JSW采样点不同浓度Dl PCBs提取物暴露斑马鱼胚胎96 h后,使斑马鱼仔鱼cyp1a m RNA相对表达量是对照组的3.36~19.45倍。说明一定浓度的近海沉积物Dl PCBs能诱导斑马鱼仔鱼EROD酶活性和cyp1a m RNA表达量升高,且呈现浓度-效应关系。聂芳红 蔡吉榛 王小宁 林红英 Ravi Gooneratne Anthony Hay 马驿 巨向红 郑锦庆 陈进军 2016生态毒理学报2016,11,2:1

8Effect of transplant center volume on post-transplant survival in patients listed for simultaneous liver and kidney transplantation显示文摘AIM To examine the effect of center size on survival differences between simultaneous liver kidney transplantation(SLKT) and liver transplantation alone(LTA) in SLKT-listed patients.METHODS The United Network of Organ Sharing database was queried for patients ≥ 18 years of age listed for SLKT between February 2002 and December 2015. Posttransplant survival was evaluated using stratified Cox regression with interaction between transplant type(LTA vs SLKT) and center volume.RESULTS During the study period, 393 of 4580 patients(9%) listed for SLKT underwent a LTA. Overall mortality was higher among LTA recipients(180/393, 46%) than SLKT recipients(1107/4187, 26%). The Cox model predicted a significant survival disadvantage for patients receiving LTA vs SLKT [hazard ratio, hazard ratio(HR) = 2.85; 95%CI: 2.21, 3.66; P < 0.001] in centers performing 30 SLKT over the study period. This disadvantage was modestly attenuated as center SLKT volume increased, with a 3% reduction(HR = 0.97; 95%CI: 0.95, 0.99; P = 0.010) for every 10 SLKs performed.CONCLUSION In conclusion, LTA is associated with increased mortality among patients listed for SLKT. This difference is modestly attenuated at more experienced centers and may explain inconsistencies between smaller-center and larger registry-wide studies comparing SLKT and LTA outcomes.Rohan M Modi Dmitry Tumin Andrew J Kruger Eliza W Beal Don Hayes Jr James Hanje Anthony J Michaels Kenneth Washburn Lanla F Conteh Sylvester M Black Khalid Mumtaz 2018World Journal of Hepatology2018,10,1:0
9还记得普鲁士吗?显示文摘1897年,英国诗人罗德亚德·吉普林(Rudyard Kipling)在一首名为《礼拜退场赞美歌》的诗中写下“我们昔日的荣光终究会像尼尼微和提尔一样黯然失色”(尼尼微是古代亚述首都,提尔是古代腓尼基的港口城市)的词句,借此惋叹英国难以永续辉煌。虽然帝国似乎都难以逃脱衰落的历史宿命,波兰曾被列强分割,而塞尔维亚则被其他帝国统治了数世纪之久,不过它们最终还能重获独立。威廉·安东尼·黑尔(William Anthony Hay) 瑞升(译) 2008国外社会科学文摘2008,,5:0
10On localization with robust power control for safety critical wireless sensor networks显示文摘A hybrid methodology is proposed for use in low power, safety critical wireless sensor network applications, where quality-of-service orientated transceiver output power control is required to operate in parallel with radio frequency-based localization. The practical implementation is framed in an experimental procedure designed to track a moving agent in a realistic indoor environment. An adaptive time synchronized approach is employed to ensure the positioning technique can operate effectively in the presence of dataloss and where the transmitter output power of the mobile agent is varying due to power control. A deterministic multilateration-based positioning approach is adopted and accuracy is improved by filtering signal strength measurements overtime to account for multipath fading. The location estimate is arrived at by employing least-squares estimation. Power control is implemented at two separate levels in the network topology. First, power control is applied to the uplink between the tracking reference nodes and the centralized access point. A number of algorithms are implemented highlighting the advantage associated with using additional feedback bandwidth, where available, and also the need for effective time delay compensation. The second layer of power control is implemented on the uplink between the mobile agent and the access point and here quantifiable improvements in quality of service and energy efficiency are observed. The hybrid paradigm is extensively tested experimentally on a fully compliant 802.15.4 testbed, where mobility is considered in the problem formulation using a team of fully autonomous robots.Michael J.

11Impact of transjugular intrahepatic porto-systemic shunt on post liver transplantation outcomes: Study based on the United Network for Organ Sharing database显示文摘AIM To determine the impact of transjugular intrahepatic porto-systemic shunt(TIPS) on post liver transplantation(LT) outcomes.METHODS Utilizing the United Network for Organ Sharing(UNOS) database, we compared patients who underwent LT from 2002 to 2013 who had underwent TIPS to those without TIPS for the management of ascites while on the LT waitlist. The impact of TIPS on 30-d mortality, length of stay(LOS), and need for re-LT were studied. For evaluation of mean differences between baseline characteristics for patients with and without TIPS, we used unpaired t-tests for continuous measures and χ~2 tests for categorical measures. We estimated the impact of TIPS on each of the outcome measures. Multivariate analyses were conducted on the study population to explore the effect of TIPS on 30-d mortality post-LT, need for re-LT and LOS. All covariates were included in logistic regression analysis.RESULTS We included adult patients(age ≥ 18 years) who underwent LT from May 2002 to September 2013. Only those undergoing TIPS after listing and before liver transplant were included in the TIPS group. We excluded patients with variceal bleeding within two weeks of listing for LT and those listed for acute liver failure or hepatocellular carcinoma. Of 114770 LT in the UNOS database, 32783(28.5%) met inclusion criteria. Of these 1366(4.2%) had TIPS between the time of listing and LT. We found that TIPS increased the days on waitlist(408 ± 553 d) as compared to those without TIPS(183 ± 330 d), P < 0.001. Multivariate analysis showed that TIPS had no effect on 30-d post LT mortality(OR = 1.26; 95%CI: 0.91-1.76) and re-LT(OR = 0.61; 95%CI: 0.36-1.05). Pre-transplant hepatic encephalopathy added 3.46 d(95%CI: 2.37-4.55, P < 0.001), followed by 2.16 d(95%CI: 0.92-3.38, P = 0.001) by TIPS to LOS. CONCLUSION TIPS did increase time on waitlist for LT. More importantly, TIPS was not associated with 30-d mortality and re-LT, but it did lengthen hospital LOS after transplantation.Khalid Mumtaz Sherif Metwally Rohan M Modi Nishi Patel Dmitry Tumin Anthony J Michaels James Hanje Ashraf El-Hinnawi Don Hayes Jr Sylvester M Black 2017World Journal of Hepatology2017,9,2:0
