| 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 |
| 2 | Gastric polyps: Association with Helicobacter pylori status and the pathology of the surrounding mucosa, a cross sectional study显示文摘aim:To assess the endoscopic characteristics of gastric polyps and their association with Helicobacter pylori(H.pylori)status in a predominantly Hispanic population.m ETHODS:We conducted a retrospective study of all esophagogastroduodenoscopies performed at our institution.Demographic,endoscopic and histopathological data were reviewed.Categorization of patients into Hispanic and Non-Hispanic was based on selfidentification.Patients without resection/biopsy were not included in the analysis.Identification of polyps type was based on histological examination.One way analysis of variance was used to compare continuousvariables among different polyp types and Fisher’s exact test was used compare categorical variables among polyp types.Unadjusted and adjusted comparisons of demographic and clinical characteristics were performed according to the H.pylori status and polyp type using logistic regressions.RESULTS:Of 7090 patients who had upper endoscopy,335 patients had gastric polyps(4.7%).Resection or biopsy of gastric polyps was performed in 296 patients(88.4%)with a total of 442 polyps removed or biopsied.Of 296 patients,87(29%)had hyperplastic polyps,82(28%)had fundic gland polyps and 5(1.7%)had adenomatous polyps.Hyperplastic polyps were significantly associated with positive H.pylori status compared with fundic gland polyps(OR=4.621;95%CI:1.92-11.13,P=0.001).Hyperplastic polyps were also found to be significantly associated with portal hypertensive gastropathy compared with fundic gland polyps(OR=6.903;95%CI:1.41-33.93,P=0.0174).Out of 296 patients,30(10.1%)had a followup endoscopy with a mean duration of 26±16.3 mo.Interval development of cancer was not noted in any of the patients during follow up period.CONCLUSi ON:Gastric hyperplastic polyps were significantly associated with positive H.pylori status and portal hypertensive gastropathy as compared with fundic gland polyps. | Sherif Elhanafi Mohammed Saadi Wynee Lou Indika Mallawaarachchi Alok Dwivedi Marc Zuckerman Mohamed O Othman | 2015 | World Journal of Gastrointestinal Endoscopy2015,7,10: | 18 |
| 3 | 让肾脏健康人人可享,处处可及——从预防到诊治显示文摘Around 850 million people currently are affected by different types of kidney disorders.Up to 1 in 10 adults worldwide has chronic kidney disease(CKD),which is invariably irreversible and mostly progressive.The global burden of CKD is increasing,and CKD is projected to become the fifth most common cause of years of life lost globally by 2040.If CKD remains uncontrolled and if the affected person survives the ravages of cardiovascular and other complications of the disease,CKD progresses to endstage kidney disease,where life cannot be sustained without dialysis therapy or kidney transplantation.Hence,CKD is a major cause of catastrophic health expenditure. | Philip Kam Tao Guillermo Garcia Garcia Siu Fai Lui Sharon Andreoli Winston Wing Shing Fung Anne Hradsky Latha Kumaraswami Vassilios Liakopoulos Ziyoda Rakhimova Gamal Saadi Luisa Strani Ifeoma Ulasi Kamyar Kalantar Zadeh 无 | 2020 | 肾脏病与透析肾移植杂志2020,29,1: | 6 |
| 4 | Glycogenic hepatopathy显示文摘Background: Glycogenic hepatopathy(GH) is a disorder associated with uncontrolled diabetes mellitus,most commonly type 1, expressed as right upper quadrant abdominal pain, hepatomegaly and increased liver enzymes. The diagnosis may be difficult, because laboratory and imaging tests are not pathognomonic. Although GH may be suggested based on clinical presentation and imaging studies, the gold standard for diagnosis is a liver biopsy, showing a significant accumulation of glycogen within the hepatocytes. GH may be diagnosed also after elevated liver enzymes in routine blood tests. GH usually regresses after tight glycemic control. Progression to end-stage liver disease has never been reported. This review aims to increase the awareness to this disease, to suggest a pathway for investigation that may reduce the use of unnecessary tests, especially invasive ones.Data sources: A Pub Med database search(up to July 1, 2017) was done with the words 'glycogenic hepatopathy', 'hepatic glycogenosis', 'liver glycogenosis' and 'diabetes mellitus-associated glycogen storage hepatopathy'. Articles in which diabetes mellitus-associated liver glycogen accumulation was described were included in this review.Results: A total of 47 articles were found, describing 126 patients with GH. Hepatocellular disturbance was more profound than cholestatic disturbance. No synthetic failure was reported.Conclusions: GH may be diagnosed conservatively, based on corroborating medical history, physical examination, laboratory tests, imaging studies and response to treatment, even without liver biopsy. In case of doubt about the diagnosis or lack of clinical response to treatment, a liver biopsy may be considered.There is no role for noninvasive tests like fibroscan or fibrotest for the diagnosis of GH or for differentiation of this situation from nonalcoholic fatty liver disease. | Johad Khoury Yaniv Zohar Naim Shehadeh Tarek Saadi | 2018 | Hepatobiliary & Pancreatic Diseases International2018,17,2: | 5 |

| 6 | Impact of the Travelling Magnetic Field on the Metallic Impurities During the Crystallization of Photovoltaic Silicon显示文摘Silicon is the most extensively studied semiconductor mainly owing to its wide applicability in the photovoltaic solar cell industry.However the qualily of Si photovoltaic cells depends on the purity of the material and on the grain structure of the ingot from which the wafers are cutting.The electrical performance of such materials,i.e.mainly their minority carrier lifetime,is closely related to metal impurities present in the feedstock or introduced during crystal growth.These impurities strongly interact with existing crystal defects to form complexes,accumulate at dislocations or grain boundaries in different forms,or even form silieide precipitates,which simultaneously contain several metal impurities.In such a context,it is necessary to control the segregation of impurities especially metallic in the grown ingot in order to optimize the cell properties as a function of the raw material purity.A new Bridgman set-up is developed in order to study the crystallization of photovoltaic Si under independently controlled solidification parameters growth rate,thermal gradient,purity and convection.Convection,either natural or forced,plays a very important role during the crystallization.Its intensity and flow pattern affect heat and mass transfer and,consequently,macrostructure and segregation in a solidified ingot.Here the convection can be controlled by a travelling magnetic field in order to homogenize or segregate the rejected impurities such as metallic elements.The effects of the magnetic field intensity and frequency on the segregation and crystalline structure will be presented. | Kader Zaidat Mircea Cablea Abdallah Nouri Ghatfan Hassan Bachir Saadi Olga.Budenkova Annie.Gagnoud Yves.Delannoy | 2012 | Journal of Iron and Steel Research(International)2012,19,S1: | 2 |
| 7 | A Hybrid Circuit Breaker Based on Current Commutation Approach for Multi-feeder DC Railway Substations显示文摘The paper presents an economic hybrid circuit breaker for limiting and interrupting the faults in DC railways substations. For fast fault current interruption, the hybrid breaker incorporates high speed mechanical contacts actuated by power semiconductor devices. Additionally, to avoid formation of electric arc, a commutation circuit is used to inject a counter current during fault interruption. In a real railway substation, each feeder is connected to the main DC bus through an expensive air magnetic DC circuit breaker and to an auxiliary DC bus through another expensive breaker. This leads to high cost especially in railway substation with multi feeders which are used to energize the vehicle transmission lines. In this paper, all DC breakers in DC railway substations are replaced by the suggested circuit breaker, which consists of a high speed mechanical contact with two semiconductor devices in each feeder and only one commutation circuit for injecting the counter current in all faulted feeders. The fault diagnosis is designed to detect the abnormal condition (current or voltage) in all feeders and direct the injected current from the commutation circuit to the faulted feeder only when the abnormal reaches a predetermine level. The suggested breaker is able to detect and interrupt any cascading of faults. | Saady Hasan | 2019 | CSEE Journal of Power and Energy Systems2019,5,2: | 2 |
| 8 | Superselective embolisation of bilateral superior vesical arteries for management of intractable hematuria in context of metastatic bladder cancer显示文摘Hematuria due to locally advanced or metastatic bladder cancer is a common condition and is often a management problem.Percutaneous embolisation is a mini-invasive option to handle this situation.We report a case of a patient with a metastatic bladder cancer and who presented with an abundant hematuria and severe anemia.After failure of endoscopic resections and“flush”of radiotherapy haemostatic and refusal of cystectomy by the patient,he was treated by superselective embolisation of bilateral superior bladder arteries with excellent immediate results.The technique is safe and effective in the short term.The longterm effectiveness requires further investigation. | Ahmed Saadi Abderrazak Bouzouita Mohamed Hedi Rebai Mohamed Cherif Walid Kerkeni Haroun Ayed Amine Derouiche Hatem Rajhi Riadh Ben Slama Najla Mnif Mohamed Chebil | 2017 | Asian Journal of Urology2017,4,2: | 2 |

| 14 | Chidamide inhibits the NOTCH1-MYC signaling axis in T-cell acute lymphoblastic leukemia显示文摘T-cell acute lymphoblastic leukemia(T-ALL)is one of the most dangerous hematological malignancies,with high tumor heterogeneity and poor prognosis.More than 60%of T-ALL patients carry NOTCH1 gene mutations,leading to abnormal expression of downstream target genes and aberrant activation of various signaling pathways.We found that chidamide,an HDAC inhibitor,exerts an antitumor effect on T-ALL cell lines and primary cells including an anti-NOTCH1 activity.In particular,chidamide inhibits the NOTCH1-MYC signaling axis by down-regulating the level of the intracellular form of NOTCH1(NICD1)as well as MYC,partly through their ubiquitination and degradation by the proteasome pathway.We also report here the preliminary results of our clinical trial supporting that a treatment by chidamide reduces minimal residual disease(MRD)in patients and is well tolerated.Our results highlight the effectiveness and safety of chidamide in the treatment of T-ALL patients,including those with NOTCH1 mutations and open the way to a new therapeutic strategy for these patients. | Mengping Xi Shanshan Guo Caicike Bayin Lijun peng Florent Chuffart Ekaterina Bourova-Flin Sophie Rousseaux Saadi Khochbin Jian-Qing Mi Jin Wang | 2022 | Frontiers of Medicine2022,16,3: | 1 |
