3Early repolarization syndrome: A cause of sudden cardiac death显示文摘Early repolarization syndrome(ERS), demonstrated as J-point elevation on an electrocardiograph, was formerly thought to be a benign entity, but the recent studies have demonstrated that it can be linked to a considerable risk of life- threatening arrhythmias and sudden cardiac death(SCD). Early repolarization characteristics associated with SCD include high-amplitude J-point elevation, horizontal and/or downslopping ST segments, and inferior and/or lateral leads location. The prevalence of ERS varies between 3% and 24%, depending on age, sex and J-point elevation(0.05 m V vs 0.1 m V) being the main determinants.ERS patients are sporadic and they are at a higher risk of having recurrent cardiac events. Implantable cardioverter-defibrillator implantation and isoproterenol are the suggested therapies in this set of patients. On the other hand, asymptomatic patients with ERS are common and have a better prognosis. The risk stratification in asymptomatic patients with ERS still remains a grey area. This review provides an outline of the up-to-date evidence associated with ERS and the risk of life- threatening arrhythmias. Further prospective studies are required to elucidate the mechanisms of ventricular arrhythmogenesis in patients with ERS.Abdi Ali Nida Butt Azeem S Sheikh 2015World Journal of Cardiology2015,7,8:9

6Radiofrequency ablation for early oesophageal squamous neoplasia:Outcomes form United Kingdom registry显示文摘AIM:To report outcomes on patients undergoing radiofrequency ablation(RFA)for early oesophageal squamous neoplasia from a National Registry.METHODS:A Prospective cohort study from 8 tertiary referral centres in the United Kingdom.Patients with squamous high grade dysplasia(HGD)and early squamous cell carcinoma(ESCC)confined to the mucosa were treated.Visible lesions were removed by endoscopic mucosal resection(EMR)before RFA.Following initial RFA treatment,patients were followed up 3monthly.Residual flat dysplasia was treated with RFA until complete reversal dysplasia(CR-D)was achieved or progression to invasive Squamous cell cancer defined as infiltration into the submucosa layer or beyond.The main outcome measures were CR-D at 12 mo from start of treatment,long term durability,progression to cancer and adverse events.RESULTS:Twenty patients with squamous HGD/ESCC completed treatment protocol.Five patients(25%)had EMR before starting RFA treatment.CR-D was 50%at12 mo with a median of 1 RFA treatment,mean 1.5(range 1-3).Two further patients achieved CR-D with repeat RFA after this time.Eighty per cent with CR-D remain dysplasia free at latest biopsy,with median follow up 24 mo(IQR 17-54).Six of 20 patients(30%)progressed to invasive cancer at 1 year.Four patients(20%)required endoscopic dilatations for symptomatic structuring after treatment.Two of these patients have required serial dilatations thereafter for symptomatic dysphagia with a median of 4 dilatations per patient.The other 2 patients required only a single dilatation to achieve an adequate symptomatic response.One patient developed cancer during follow up after end of treatment protocol.CONCLUSION:The role of RFA in these patients re-mains unclear.In our series 50%patients responded at12 mo.These figures are lower than limited published data.Rehan J Haidry Mohammed A Butt Jason Dunn Matthew Banks Abhinav Gupta Howard Smart Pradeep Bhandari Lesley Ann Smith Robert Willert Grant Fullarton Morris John Massimo Di Pietro Ian Penman Marco Novelli Laurence B Lovat 2013World Journal of Gastroenterology2013,19,36:7
7经中央循环体外膜氧合治疗儿童难治性脓毒性休克(摘要)显示文摘目的因脓毒症住院的患儿病死率很高,发生休克是导致死亡最重要的风险因素。对任何常规治疗均无效的脓毒性休克患儿,推荐使用体外膜氧合(ECMO),但预期存活率仅为50%,且该技术的最佳应用方法尚不明确。近年来,我们尝试直接经胸腔置管(经中央循环,心房-主动脉ECMO)以期达到更高血流流速。MacLaren G Butt W Best D 杨明(译) 钱素云(校) 2011中国小儿急救医学2011,18,2:7
8美国花生脱壳机研究现状及发展分析显示文摘脱壳是花生利用前必经环节,脱壳机是花生产后加工的核心设备,在很大程度上决定了花生的果仁质量和脱壳效率。中国虽然花生产量位居世界第一,且花生脱壳机得到广泛应用,但花生脱壳技术远不及美国,严重制约花生产后加工业的发展。为借鉴美国花生脱壳技术及发展经验,在实地考察基础上,运用社会调查法、文献研究法和经验总结等方法,本文分析了美国花生脱壳机的发展历史、最新进展和技术衍变过程,剖析了美国现代花生脱壳机的脱壳原理、总体构成、脱壳部件结构型式和特点,总结了美国花生脱壳技术研究的基本方法和成功经验。结果显示,美国花生脱壳机研究密切结合生产需要,起步早且不断创新;多滚筒大型脱壳机既可用于榨油和食品加工的花生脱壳,也可用于种子花生脱壳,各滚筒之间独立驱动,转速200~300 r/min;脱壳机构由带有刮板的脱壳打杆和钢制栅片凹板筛构成,对花生荚果进行刮搓脱壳;复式清选装置首先进行气吸除壳、然后进行筛选和二次气吸清选。美国花生脱壳机技术是机械与农艺等多方面融合研究的结果,对中国花生脱壳技术研究及进展具有重要借鉴意义。陆荣 刘志侠 高连兴 CHEN Charles BUTTS Christopher Lloyd 2020华中农业大学学报2020,39,2:6

10中国城市生活垃圾处置状况及治理研究显示文摘中国城市生活垃圾存量高、增速快,生活垃圾治理要真正实现“减量化、无害化、资源化”的目标,面临着垃圾分类不规范、情境性强、区域间发展不平衡、公众参与效率低、“运动式”治理等困境。基于全国城市生活垃圾处置历年数据分析,2005—2019年全国城市生活垃圾清运量呈逐步上升趋势,区域间垃圾清运量、处理方式与处理能力存在明显差异。政府包揽型垃圾治理模式导致政府负担重,治理效率低等问题,构建政府、公众、市场、专业机构、媒体和非营利组织等多元主体参与的治理体系,是破解我国城市生活垃圾治理困境的必由之路。龚文娟 赵曌 BUTT A W 2022海南大学学报(人文社会科学版)2022,40,3:6
11Optical multiplexing techniques and their marriage for on-chip and optical fiber communication:a review显示文摘Herein,an attention-grabbing and up-to-date review related to major multiplexing techniques is presented which in-cludes wavelength division multiplexing(WDM),polarization division multiplexing(PDM),space division multiplexing(SDM),mode division multiplexing(MDM)and orbital angular momentum multiplexing(OAMM).Multiplexing is a mech-anism by which multiple signals are combined into a shared channel used to showcase the maximum capacity of the op-tical links.However,it is critical to develop hybrid multiplexing methods to allow enhanced channel numbers.In this re-view,we have also included hybrid multiplexing techniques such as WDM-PDM,WDM-MDM and PDM-MDM.It is prob-able to attain N×M channels by utilizing N wavelengths and M guided-modes by simply utilizing hybrid WDM-MDM(de)multiplexers.To the best of our knowledge,this review paper is one of its kind which has highlighted the most prom-inent and recent signs of progress in multiplexing techniques in one place.Svetlana Nikolaevna Khonina Nikolay Lvovich Kazanskiy Muhammad Ali Butt Sergei Vladimirovich Karpeev 2022Opto-Electronic Advances2022,5,8:6
12Overexpressed BRH1, a RING finger gene, alters rosette leaf shape in Arabidopsis thaliana显示文摘Leaves are the most important plant parts for photosynthesis and respiration. Many genes are involved in determining leaf shape;however, little is known about the effects of brassinosteroid (BR) signaling-pathway genes on the development of leaf shape. Here, the brassinosteroid-responsive RING-H2 (BRH1) gene, which is suppressed by 24-epi-brassinolide treatment, was isolated from Arabidopsis thaliana. The amino acid sequence contained a highly conserved RING finger domain. In a phylogenetic analysis,BRH1 clustered closely with GLYMA11G02470.1. The leaves of brh1 mutant plants were not much different to those of the wild-type, while transgenic plants with high BRH1 expression levels had rounder rosette leaves. Mutants of the BR synthesis pathway also had a similar round leaf phenotype, and greater BRH1 expression levels. Moreover, the related marker genes KNAT1,AtHB13 and ROT4, which are known to control leaf shape, altered transcriptional levels in both transgenic BRH1 and BR-synthesis mutant lines. Thus, BRH1 may be involved in the BR signaling pathway and regulate the growth and development of rosette leaves. Research on BRH1 may prove valuable for understanding the regulatory mechanism of leaf shape and improving the leaf shapes of ornamental plants.Xiaoqian Wang Eryong Chen Xiaoyang Ge Qian Gong HamamaIslam Butt Chaojun Zhang Zuoren Yang Fuguang Li Xueyan Zhang 2018Science China(Life Sciences)2018,61,1:5
13Lipid dysregulation in hepatitis C virus, and impact of statin therapy upon clinical outcomes显示文摘The hepatitis C virus(HCV) is one of the most common causes of chronic liver disease and the leading indication for liver transplantation worldwide. Every aspect of the HCV life cycle is closely tied to human lipid metabolism. The virus circulates as a lipid-rich particle, utilizing lipoprotein cell receptors to gain entry into the hepatocyte. It has also been shown to upregulate lipid biosynthesis and impair lipid degradation, resulting in significant intracellular lipid accumulation and circulating hypocholesterolemia. Patients with chronic hepatitis C(CHC) are at increased risk of hepatic steatosis, fibrosis, and cardiovascular disease including accelerated atherosclerosis. HMG Co A Reductase inhibitors, or statins, have been shown to play an important role in the modulation of hepatic steatosis and fibrosis, and recent attention has focused upon their potential therapeutic role in CHC. This article reviews the hepatitis C viral life cycle as it impacts host lipoproteins and lipid metabolism. It then describes the pathogenesis of HCV-related hepatic steatosis, hypocholesterolemia and atherosclerosis, and finally describes the promising anti-viral and anti-fibrotic effects of statins, for the treatment of CHC.Tracey G Simon Adeel A Butt 2015World Journal of Gastroenterology2015,21,27:5
14Estimation and inter-comparison of dust aerosols based on MODIS, MISR and AERONET retrievals over Asian desert regions显示文摘This study presents detailed analysis of spatiotemporal variations and trend of dust optical properties i.e., Aerosol Optical Depth(AOD) and Angstrom component over Asian desert regions using thirteen years of data(i.e., 2001–2013) retrieved from Aerosol Robotic Network(AERONET), Moderate Resolution Imaging Spectroradiometer(MODIS) and Multi-angle Imaging Spectroradiometer(MISR). These regions include Solar Village, Dunhuang and Dalangzadgad and are considered as origin of desert aerosols in Asia. Mann–Kendall trend test was used to show the trend of AOD. The relationship of AOD with weather parameters and general AOD trend over different wavelengths has also been shown. AOD's trend has been observed significant throughout the year in Solar Village, while in Dunhuang and Dalanzadgad the significant trend has been found only in peak period(March–June).Analysis show high values of AOD and low values of angstrom in Solar Village during peak period. In Chinese desert regions, high values of AOD have been found during peak period and low values in pre-peak period. Significant relationship has been observed between AOD and average temperature in Solar Village and Dalanzadgad whereas rainfall and wind speed showed no significant impact on AOD in all desert regions.Ammara Habib Bin Chen Bushra Khalid Saichun Tan Huizheng Che Tariq Mahmood Guangyu Shi Muhammad Tahir Butt 2019Journal of Environmental Sciences2019,31,2:5
15Impact of direct acting antivirals on occurrence and recurrence of hepatocellular carcinoma: Biologically plausible or an epiphenomenon?显示文摘Hepatocellular carcinoma(HCC) is a major cause of morbidity and mortality worldwide. Chronic hepatitis C virus infection(HCV) is the most common cause of HCC in many European countries, Japan and Pakistan. Introduction of the new direct acting antivirals(DAAs) has revolutionized the management of HCV worldwide, with high rates of sustained virologic response in patients who could not have tolerated the previous interferon based treatments. However, recently there have been reports raising caution about the long term effects of DAAs, particularly a possible increased risk of HCC. Therefore this review explores the current molecular studies as well as clinical data that investigate the impact of DAAs on occurrence and recurrence of HCC.Amna Subhan Butt Fatima Sharif Shahab Abid 2018World Journal of Hepatology2018,10,2:4

19Effects of Magnetic Field on Entropy Generation in Flow and Heat Transfer due to a Radially Stretching Surface显示文摘We investigate the effects of magnetic field on the entropy generation during fluid flow and heat transfer due to the radially stretching surface.The partial differential equations governing the flow and heat transfer phenomenon are transformed into nonlinear ordinary differential equations by using suitable similarity transformations.These equations are then solved by the homotopy analysis method and the shooting technique.The effects of the magnetic field parameter M and the Prandtl number Pr on velocity and the temperature profiles are presented.Moreover,influence of the magnetic field parameter M and the group parameter Br/Ω on the local entropy generation number Ns as well as the Bejan number Be are inspected.It is observed that the magnetic field is a strong source of entropy production in the considered problem.Adnan Saeed Butt Asif Ali 2013Chinese Physics Letters2013,30,2:3
20Treatment of hepatitis C virus genotype 4 with peginterferon alfa-2a: Impact of bilharziasis and fibrosis stage显示文摘AIM: To evaluate pegylated interferon alpha2a (PegIFN- α2a) in Egyptian patients with HCV genotype 4, and the impact of pretreatment viral load, co-existent bilharziasis and histological liver changes on response rate. METHODS: A total of 73 na?ve patients (61 with history of bilharziasis) with compensated chronic HCV genotype 4 were enrolled into: group A (38 patients) who received 180 mg PegIFN-alpha2a subcutaneously once weekly for a year and group B (35 patients) received IFN alpha-2a 3 MU 3 times weekly. Ribavirin was added to each regimen at a dose of 1200 mg. Patients were followed for 72 wk and sustained response was assessed. RESULTS: Significant improvement in both end of treatment response (ETR) (P < 0.002) and sustained response (SR) (P < 0.05) was noted with pegylated interferon, where ETR was achieved in 29 (76.3%) and 14 patients (40%) in both groups respectively, and 25 patients in group A (65.8%) and 9 (25.7%) in group B could retain negative viraemia by the end of follow up period. Sustained virological response (SVR) showed a significant negative correlation with age and positive correlation with pretreatment inflammation in patients receiving PegIFN. Viral clearance after 3 mo of therapy was associated with high incidence of ETR and SR (P < 0.001), but without significant difference between both forms of interferon. Significant improvement in response was achieved in patients with high grade fibrosis (grade 3 and 4) with PegIFN-α2a, where SR was seen in 5 out of 13 patients in group A, but none in group B. There was no significant difference in response betweenbilharzial and non-bilharzial patients in both groups. In terms of safety and tolerability, neutropenia was the predominant side effect; both drugs were comparable. CONCLUSION: PegIFN-α2a combined with ribavirin results in improvement in sustained response in HCV genotype 4, irrespective of history of bilharzial infestation.MF Derbala SR Al Kaabi NZ El Dweik F Pasic MT Butt R Yakoob A Al-Marri AM Amer N Morad A Bener 2006World Journal of Gastroenterology2006,12,35:3
