1虚拟货币及其扩展:初步思考显示文摘随着信息加密和网络计算机技术日趋成熟,科技正在推动全球经济的转型变革。虚拟货币的产生在此过程中又显得至关重要。虚拟货币方案在许多情况下便于对等网络交互绕过传统的中央结算所。虚拟货币及其关联技术(特别是基于区块链的分布式账本)正在迅速发展,其未来前景难以预测。虚拟货币带来了许多潜在益处,包括更快速、高效的支付和转账等,并将最终促进普惠金融。一些虚拟货币方案背后的分布式账本技术提供的潜在益处将远超虚拟货币本身。但是,虚拟货币的出现也引发了许多潜在风险,如成为洗钱、恐怖融资、偷税漏税和欺诈等犯罪的工具。虚拟货币虽然目前的规模仍非常有限,对现阶段货币政策实施产生的风险亦甚微,但随着新技术的广泛应用,其对金融稳定产生的影响会日益显现。有关虚拟货币的有效监管对策还处于起步阶段。虚拟货币的在国家层面跨越了不同机构的职责,并在全球范围内操作,其监管难度很大。并且,许多虚拟货币在传统金融系统之外运作,缺乏透明度,其操作过程更难以被监管。各国监管机构已开始着手应对这些挑战且方式各异。需要注意的是,国家主管部门需认真权衡监管方式,既要适当处置风险又不能扼杀创新。为了在国家层面推进发展进程和促进政策的完善,国际层面也应进行更多努力。随着经验的不断积累,可考虑提出国际标准和最优方法,为不同领域的最优监管对策提供指导,从而促进跨辖区的协调。也可在此类标准基础上,为一些领域设立跨国合作和协调的框架。何东 卡尔·哈伯梅尔 罗斯·莱科 郭建伟 郇志坚 Vikram Haksar Yasmin Almeida Mikari Kashima Nadim Kyriakos-Saad Hiroko Oura Tahsin Saadi Sedik Natalia Stetsenko Concepcion Verdugo.Yepes 2016金融监管研究2016,,4:22
2Total thyroidectomy is safer with identification of recurrent laryngeal nerve显示文摘Objective:To investigate the effect of recurrent laryngeal nerve(RLN)identification on the complications after total thyroidectomy and lobectomy.Methods:Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively.Patients were divided into two groups:RLN identified (Group A)or not(Group B).The two groups were compared for RLN injury and hypocalcaemia.Results:The numbers of patients and nerves at risk were 71 and 129 in Group A,and 63 and 121 in Group B,respectively.RLN injury in Group A(0)was sig- nificantly lower than that in Group B(57.9%)patients,75.8%nerves)for the numbers of patients(P=0.016)and nerves at risk (P=0.006).Temporary hypocalcaemia was significantly higher in Group A than in Group B(1424.1%vs 610.3%,P=0.049). Permanent complications in Group B were significantly higher than those in Group A(1320.6%vs 45.6%,P=0.009).Con- clusion:RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.Hakan CANBAZ Musa DIRLIK Tahsin COLAK Koray OCAL Tamer AKCA Oner BILGIN Bahar TASDELEN Suha AYDIN 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,6:20
3Drainage after total thyroidectomy or lobectomy for benign thyroidal disorders显示文摘Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.Tahsin COLAK Tamer AKCA Ozgur TURKMENOGLU Hakan CANBAZ Bora USTUNSOY Arzu KANIK Suha AYDIN1 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,4:12
4Research on Bulbous Bow Optimization Based on the Improved PSO Algorithm显示文摘In order to reduce the total resistance of a hull, an optimization framework for the bulbous bow optimization was presented. The total resistance in calm water was selected as the objective function, and the overset mesh technique was used for mesh generation. RANS method was used to calculate the total resistance of the hull. In order to improve the efficiency and smoothness of the geometric reconstruction, the arbitrary shape deformation(ASD)technique was introduced to change the shape of the bulbous bow. To improve the global search ability of the particle swarm optimization(PSO) algorithm, an improved particle swarm optimization(IPSO) algorithm was proposed to set up the optimization model. After a series of optimization analyses, the optimal hull form was found.It can be concluded that the simulation based design framework built in this paper is a promising method for bulbous bow optimization.ZHANG Sheng-long ZHANG Bao-ji Tahsin TEZDOGAN XU Le-ping LAI Yu-yang 2017China Ocean Engineering2017,31,4:4
5In vitro effect of pantoprazole on lower esophageal sphincter tone in rats显示文摘AIM:To investigate the in vitro effects of pantoprazole on rat lower esophageal sphincter(LES)tone.METHODS:Rats weighing 250-300 g,provided by the Yeditepe University Experimental Research Center(Yü-DETAM),were used throughout the study.They were anesthetized before decapitation.LES tissues whose mucosal lining were removed were placed in a stan-dard 30-mL organ bath with a modif ied Krebs solution and continuously aerated with 95% oxygen-5% carbon dioxide gas mixture and kept at room temperature.The tissues were allowed to stabilize for 60 min.Sub-sequently,the contractile response to 10-6 mol/L carba-chol was obtained.Different concentrations of freshly prepared pantoprazole were added directly to the tis-sue bath to generate cumulative concentrations of 5×10-6 mol/L,5×10-5 mol/L,and 1.5×10-4 mol/L.Activi-ties were recorded on an online computer via a 4-channeltransducer data acquisition system using the software BSL PRO v 3.7,which also analyzed the data.RESULTS:Pantoprazole at 5×10-6 mol/L caused a small,but statistically insignif icant,relaxation in the car-bachol-contracted LES(2.23% vs 3.95%).The 5×10-5 mol/L concentration,however,caused a signif icant relax-ation of 10.47% compared with the control.1.5×10-4 mol/L concentration of pantoprazol caused a 19.89% relaxation in the carbachol contracted LES(P<0.001).CONCLUSION:This is the fi rst study to demonstrate that pantoprazole has a relaxing effect in isolated LESs.These results might have signif icant clinical implications for the subset of patients using proton pump inhibitors who do not receive full symptomatic alleviation from gastroesophageal reflux disease.Mustafa Duman Mahmut zer Enver Rean Yeliz Demirci Ali E Atιcι Tahsin Dalgι Erdal B Bostancι Ece Gen 2011World Journal of Gastroenterology2011,17,46:3
