| 1 | Role of laparoscopic common bile duct exploration in the management of choledocholithiasis显示文摘Surgical fraternity has not yet arrived at any consensus for adequate treatment of choledocholithiasis. Sequential treatment in the form of pre-operative endoscopic retrograde cholangio-pancreatography followed by laparoscopic cholecystectomy(LC) is considered as optimal treatment till date. With refinements in technique and expertise in field of minimal access surgery, many centres in the world have started offering one stage management of choledocholithiasis by LC with laparoscopic common bile duct exploration(LCBDE). Various modalities have been tried for entering into concurrent common bile duct(CBD) [transcystic(TC) vs transcholedochal(TD)], for confirming stone clearance(intraoperative cholangiogram vs choledochoscopy), and for closure of choledochotomy(T-tube vs biliary stent vs primary closure) during LCBDE. Both TC and TD approaches are safe and effective. TD stone extraction is involved with an increased risk of bile leaks and requires more expertise in intra-corporeal suturing and choledochoscopy. Choice depends on number of stones, size of stone, diameter of cystic duct and CBD. This review article was undertaken to evaluate the role of LCBDE for the management of choledocholithiasis. | Nikhil Gupta | 2016 | World Journal of Gastrointestinal Surgery2016，8，5： | 40 |
| 2 | Diagnosis of Crohn's disease in India where tuberculosis is widely prevalent显示文摘AIM:To define the parameters that positively predict diagnosis of Crohn's disease (CD) and differentiate it from gastrointestinal tuberculosis (GITB). METHODS:This prospective study over 3 years was carried out in the consecutive Indian patients with definite diagnosis of CD and equal numbers of patients with definite diagnosis of GITB. Demographic, clinical, laboratory, morphological and histological features were noted in all the patients. Serological tests such as p-ANCA, c-ANCA, IgA ASCA and IgG ASCA, were performed. Endoscopic biopsy and/or surgical tissue specimens were subjected to smear and culture for acid-fast bacilli (AFB) and tissue polymerase chain reaction for tuberculosis (TB PCR). Diagnosis of CD and GITB was based on the standard criteria. Data were analyzed using univariate Chi-square test and multiple logistic regression (MLR). RESULTS:The study is comprised of 26 patients with CD (age 36.6 ± 8.6 year, male:female, 16:10) and 26 patients with GITB (age 37.2 ± 9.6 year, male:female, 15:11). The following clinical variables between the two groups (CD vs TB) were significant in univariate analysis:duration of symptoms (58.1 ± 9.8 vs 7.2 ± 3.4 mo), diarrhoea (69.2% vs 34.6%), bleeding per rectum (30.7% vs 3.8%), fever (23.1% vs 69.2%), ascites (7.7% vs 34.6%) and extra-intestinal manifestations of inflammatory bowel disease (61.5% vs 23.1%). Of these, all except ascites and extra-colonic manifestations were found statistically significant by MLR. Accuracy of predicting CD was 84.62% based on the fever, bleeding P/R, diarrhoea and duration of symptoms while it was 63.4% when histology was reported as inflammatory bowel disease and 42.3% when there was recurrence of disease after surgery. Accuracy of predicting GITB was 73.1% when there was co-existing pulmonary lesions and/or abdominal lymphadenopathy;75% when tuberculosis was reported in histology;63.4% when granuloma was found in histology;82.6% when TB PCR was positive;and 61.5% when smear and/ or culture was positive for AFB. Serological test was not useful in differentiation of CD from GITB. Positivity rates for CD and GITB were:p-ANCA-3.8% and 3.8%, c-ANCA-3.8% and 0%, IgA ASCA-38.4% and 23.1%, and IgG ASCA-38.4% and 42.3%, respectively. CONCLUSION:Simple clinical parameters like fever, bleeding P/R, diarrhoea and duration of symptoms have the highest accuracy in differentiating CD from GITB. | Deepak N Amarapurkar Nikhil D Patel Priyamvada S Rane | 2008 | World Journal of Gastroenterology2008，14，5： | 24 |
| 3 | Role of live microbial feed supplements with reference to anaerobic fungi in ruminant productivity: A review显示文摘To keep the concept of a safe food supply to the consumers, animal feed industries world over are showing an increasing interest in the direct-fed microbials(DFM) for improved animal performance in terms of growth or productivity. This becomes all the more essential in a situation, where a number of the residues of antibiotics and/or other growth stimulants reach in milk and meat with a number of associated potential risks for the consumers. Hence, in the absence of growth stimulants, a positive manipulation of the rumen microbial ecosystem to enhance the feedstuff utilization for improved production efficiency by ruminants has become of much interest to the researchers and entrepreneurs. A few genera of live microbes(i.e., bacteria, fungi and yeasts in different types of formulations from paste to powder) are infrequently used as DFM for the domestic ruminants. These DFM products are live microbial feed supplements containing naturally occurring microbes in the rumen. Among different DFM possibilities, anaerobic rumen fungi(ARF) based additives have been found to improve ruminant productivity consistently during feeding trials. Administration of ARF during the few trials conducted, led to the increased weight gain, milk production, and total tract digestibility of feed components in ruminants. Anaerobic fungi in the rumen display very strong cell-wall degrading cellulolytic and xylanolytic activities through rhizoid development, resulting in the physical disruption of feed structure paving the way for bacterial action. Significant improvements in the fiber digestibility were found to coincide with increases in ARF in the rumen indicating their role. Most of the researches based on DFM have indicated a positive response in nutrient digestion and methane reducing potential during in vivo and/or in vitro supplementation of ARF as DFM. Therefore, DFM especially ARF will gain popularity but it is necessary that all the strains are thoroughly studied for their beneficial properties to have a confirmed ‘generally regarded as safe' status for ruminants. | Anil K Puniya Abdelfattah Z M Salem Sanjay Kumar Sumit S Dagar Gareth W Griffith Monica Puniya Sreenivas R Ravella Nikhil Kumar Tejpal Dhewa Ravinder Kumar | 2015 | Journal of Integrative Agriculture2015，14，3： | 17 |
| 4 | Optimal distributed generation allocation in radial distribution systems considering customer-wise dedicated feeders and load patterns显示文摘Distribution system planners usually provide dedicated feeders to its different class of customers,each of whom has its own characteristic load pattern which varies hourly and seasonally.A more realistic modeling should be devised by considering the daily and seasonal variations in the aggregate load patterns of different class of customers.This paper addresses a new methodology to provide integrated solution for the optimal allocation of distributed generations and network reconfiguration considering load patterns of customers.The objectives considered are to maximize annual energy loss reduction and to maintain a better node voltage profile.Bat algorithm(BA)is a new bio-inspired search algorithm which has shown an advance capability to reach into the promising region,but its exploration is inadequate.The problem is solved by proposing the improved BA(IBA).The proposed method is investigated on the benchmark IEEE 33-bus test distribution system and the results are very promising. | Neeraj KANWAR Nikhil GUPTA K.R.NIAZI Anil SWARNKAR | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，4： | 16 |
| 5 | Diagnostic accuracy of endoscopic ultrasound in pancreatic neuroendocrine tumors: A systematic review and meta analysis显示文摘AIM: To detect pancreatic neuroendocrine tumors (PNETs) has been varied. This study is undertaken to evaluate the accuracy of endoscopic ultrasound (EUS) in detecting PNETs.METHODS: Only EUS studies confirmed by surgery or appropriate follow-up were selected. Articles were searched in Medline, Ovid journals, Medline nonindexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects model). RESULTS: Initial search identified 2610 reference articles, of these 140 relevant articles were selected and reviewed. Data was extracted from 13 studies (n = 456) which met the inclusion criteria. Pooled sensitivity of EUS in detecting a PNETs was 87.2% (95%CI: 82.2-91.2). EUS had a pooled specificity of 98.0% (95%CI: 94.3-99.6). The positive likelihood ratio of EUS was 11.1 (95%CI: 5.34-22.8) and negative likelihood ratio was 0.17 (95%CI: 0.13-0.24). The diagnostic odds ratio, the odds of having anatomic PNETs in positive as compared to negative EUS studies was 94.7 (95%CI: 37.9-236.1). Begg-Mazumdar bias indicator for publication bias gave a Kendall's tau value of 0.31 (P = 0.16), indication no publication bias. The P for χ2 heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity to detect PNETs. EUS should be strongly considered for evaluation of PNETs. | Srinivas R Puli Nikhil Kalva Matthew L Bechtold Smitha R Pamulaparthy Micheal D Cashman Norman C Estes Richard H Pearl Fritz-Henry Volmar Sonu Dillon Michael F Shekleton David Forcione | 2013 | World Journal of Gastroenterology2013，19，23： | 14 |
| 6 | Changing spectrum of Budd-Chiari syndrome in India with special reference to non-surgical treatment显示文摘AIM: To evaluate patterns of obstruction, etiological spectrum and non-surgical treatment in patients with Budd-Chiari syndrome in India.METHODS: Forty-nine consecutive cases of Budd-Chiari syndrome (BCS) were prospectively evaluated. All patients with refractory ascites or deteriorating liver function were, depending on morphology of inferior vena cava (IVC) and/or hepatic vein (HV) obstruction, triaged for radiological intervention, in addition to anticoagulation therapy. Asymptomatic patients, patients with diuretic-responsive ascites and stable liver function, and patients unwilling for surgical intervention were treated symptomatically with anticoagulation.RESULTS: Mean duration of symptoms was 41.5 ± 11.2 (range = 1-240) mo. HV thrombosis (HVT) was present in 29 (59.1%), IVC thrombosis in eight (16.3%), membranous obstruction of IVC in two (4%) and both IVC-HV thrombosis in 10 (20.4%) cases. Of 35 cases tested for hypercoagulability, 27 (77.1%) were positive for one or more hypercoagulable states. Radiological intervention was technically successful in 37/38 (97.3%): IVC stenting in seven (18.9%), IVC balloon angioplasty in two (5.4%), combined IVC-HV stenting in two (5.4%), HV stenting in 11 (29.7%), transjugular intrahepatic portosystemic shunt (TIPS) in 13 (35.1%) and combined TIPS-IVC stenting in two (5.4%). Complications encountered in follow-up: death in five, re-stenosis of the stent in five (17.1%), hepatic encephalopathy in two and hepatocellular carcinoma in one patient. Of nine patients treated medically, two showed complete resolution of HVT.CONCLUSION: In our series, HVT was the predominant cause of BCS. In the last five years with the availability of sophisticated tests for hypercoagulability, etiologies weredefined in 85.7% of cases. Non-surgical management was successful in most cases. | Deepak N Amarapurkar Sundeep J Punamiya Nikhil D Patel | 2008 | World Journal of Gastroenterology2008，14，2： | 9 |
| 7 | Effect of angioembolisation versus surgical packing on mortality in traumatic pelvic haemorrhage: A systematic review and meta-analysis显示文摘BACKGROUND: The management of complex pattern of bleeding associated with pelvic trauma remains a big challenge for trauma surgeons. We aimed to conduct a comprehensive meta-analysis to compare the outcomes of angioembolisation and pelvic packing in patients with pelvic trauma.METHODS: We conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the CENTRAL; the World Health Organization International Clinical Trials Registry; Clinical Trials.gov; ISRCTN Register, and bibliographic reference lists. The primary outcome was defined as mortality. Combined overall effect sizes were calculated using randomeffects models. Results are reported as the odds ratio(OR) and 95% confidence interval(CI).RESULTS: We identified 3 observational studies reporting a total of 120 patients undergoing angioembolisation(n=60) or pelvic packing(n=60) for pelvic trauma. Reporting of the Injury Severity Score(ISS) was variable, with higher ISS in the pelvic packing group. The risk of bias was low in two studies, and moderate in one. The pooled analysis demonstrated that angioembolisation did not significantly reduce mortality in patients with pelvic trauma compared to surgery(OR=1.99; 95% CI= 0.83–4.78, P=0.12). There was mild between-study heterogeneity(I^2=0%, P=0.65).CONCLUSION: Our analysis found no significant difference in mortality between angioembolisation and pelvic packing in patients with traumatic pelvic haemorrhage. The current level of evidence in this context is very limited and insufficient to support the superiority of a treatment modality. Future research is required. | Ahmed El Muntasar Ethan Toner Oddai A.Alkhazaaleh Danaradja Arumugam Nikhil Shah Shahab Hajibandeh Shahin Hajibandeh | 2018 | World Journal of Emergency Medicine2018，9，2： | 7 |

| 9 | Big Data Thinking and Its Biomedical Application显示文摘Big data thinking gradually rise with the coming era of big data. Big data characteristics could be summarized with 4V: volume, variety, velocity and value. The characteristics of big data thinking could be summed up in integrity, fault tolerance, correlation and intelligence. These characteristics were also the primary differences between big data thinking and small data thinking. The application of big data thinking in biomedical field became more and more widely, and the most commonly used was NCBI database. The process of mining valuable information in NCBI database was big data thinking. And the rise of Meta analysis and TCGA database would illustrate the huge application value of big data thinking in the biomedical field. | Petar Melih INAL Nikhil Vishnu | 2018 | Biomed Communication2018，2，1： | 5 |
| 10 | Evaluation of graphite depressants in a poly-metallic sulfide flotation circuit显示文摘Synthetic dyes are commonly used for graphite depression in poly-metallic flotation circuits; however,these dyes can be very expensive. The aim of this study is to evaluate performance of certain low-cost alternative depressants for a complex lead-zinc(Pb-Zn) ore rich in graphite(Gr-C) on a conventional mini pilot-scale flotation circuit. The reagents used were commercial and industrial grade starch; agro-based waste-sugarcane bagasse and charred(burnt) bagasse powder. The primary evaluation criteria were quality(grades) of lead and zinc concentrates, their recoveries(%), and graphite rejection(%) in the tails.Benchmark tests using nigrosine as graphite depressant showed 94.3% rejection of Gr-C. The results with commercial starch were found as effective with 93.8% graphite rejection. Furthermore, bagasse powder showed potential in improving product quality(36.4% and 65.6% Pb grade and recovery) with an intermediate effectiveness in graphite rejection(85.6%). The order of effectiveness in Gr-C rejection follows nigrosine % commercial starch > bagasse > industrial starch > charred bagasse. In addition, the effect these depressants on silver(byproduct) grade and recovery was also investigated. | Nikhil Gupta | 2017 | International Journal of Mining Science and Technology2017，27，2： | 5 |

| 13 | Inflammation and dry eye disease——where are we?显示文摘The presence of inflammation in dry eye disease(DED)results in increased patient symptomatology,ocular surface damage and worsening tear dysfunction.It also affects the health of meibomian glands and their secretions which further aggravates ocular surface disease.This article reviews current knowledge regarding ocular surface inflammation in DED and explores the relationships between the vicious cycles of DED,inflammation and meibomian gland dysfunction(MGD).The clinical evaluation of eyes with such changes,markers that identify the presence of inflammation on the ocular surface and current treatment options are discussed. | Srinivas K Rao Rishi Mohan Nikhil Gokhale Himanshu Matalia Paras Mehta | 2022 | International Journal of Ophthalmology(English edition)2022，15，5： | 4 |
| 14 | Fecal microbial transplant for the treatment of pediatric inflammatory bowel disease显示文摘The role of fecal microbial transplant(FMT) in the treatment of pediatric gastrointestinal disease has become increasingly popular among pediatric practitioners, patients, and parents. The success of FMT for the treatment of recurrent Clostridium difficile infection(RCDI) has bolstered interest in its potential application to other disease states, such as inflammatory bowel disease(IBD). FMT has particular interest in pediatrics, given the concerns of patients and parents about rates of adverse events with existing therapeutic options, and the greater cumulative medication burden associated with childhoodonset disease. Published literature on the use of FMT in pediatrics is sparse. Only 45 pediatric patients treated for RCDI have been reported, and only 27 pediatric patients with pediatric IBD. The pediatric microbiome may uniquely respond to microbial-based therapies. This review will provide a comprehensive overview of fecal microbial transplant and its potential role in the treatment of pediatric inflammatory bowel disease. We will discuss the microbiome in pediatric inflammatory bowel disease, existing adult and pediatric literature on the use of FMT in IBD treatment, and pediatric FMT trials that are currently recruiting patients. This review will also discuss features of the microbiome that may be associated with host response in fecal transplant, and potential challenges and opportunities for the future of FMT in pediatric IBD treatment. | Alice Yuxin Wang Jelena Popov Nikhil Pai | 2016 | World Journal of Gastroenterology2016，22，47： | 4 |

| 16 | 运动后糖尿病患者下肢经皮氧分压变化的趋势(英文)显示文摘目的:研究运动对2型糖尿病患者下肢经皮氧分压( tcpO2)的影响,以探索运动时的tcpO2动态变化对糖尿病患者循环障碍的诊断价值。方法:用踩踏功率自行车运动干预方法观察了12例2型糖尿病患者(24条下肢)以及3名正常成人(6条下肢)腓肠肌tcpO2的变化情况,同时检测静息状态下的踝肱比( ABI)和定量振动阈值( QST)。根据患者ABI水平将患者肢体分成>0.9而≤1.3亚组、0.7~0.9亚组和<0.7亚组3组,比较分析各组tcpO2变化情况。结果:所有糖尿病患者的tcpO2水平在运动过程中均出现下降趋势,而正常组则出现上升趋势。在静息状态下,tcpO2运动前后的变化值与ABI呈线性相关,但与QST并无线性关系。在ABI>0.9而≤1.3亚组tcpO2在运动早期出现轻度升高,但随即下降到基础水平;在ABI为0.7~0.9亚组,tcpO2在运动初期即出现下降;在ABI<0.7亚组则出现快速下降。结论:在运动中测量tcpO2水平有助于对糖尿病患者微循环储备功能的判断。 | REGMI Nikhil 孙子林 杨兵全 | 2013 | 东南大学学报(医学版)2013，32，6： | 3 |
| 17 | Bile cast nephropathy: A case report and review of the literature显示文摘Bile cast nephropathy is a condition of renal dysfunction in the setting of hyperbilirubinemia. There are very few cases of this condition reported in the last decade and a lack of established treatment guidelines. While the exact etiology remains unknown, bile cast nephropathy is presumed to be secondary to multiple concurrent insults to the kidney including direct toxicity from bile acids, obstructive physiology from bile casts, and systemic hypoperfusion from vasodilation. Therapy directed at bilirubin reduction may improve renal function, but will likely need dialysis or plasmapheresis as well. We report our case of bile cast nephropathy and the therapeutic measures undertaken in a middle-aged male with chronic renal insufficiency that developed hyperbilirubinemia and drug-induced liver injury secondary to antibiotic use. He developed acute renal injury in the setting of rising bilirubin. He subsequently had a progressive decline in renal and hepatic function, requiring dialysis and plasmapheresis with some improvement, ultimately requiring transplantation. | Jaymon Patel Saqib Walayat Nikhil Kalva Sidney Palmer-Hill Sonu Dhillon | 2016 | World Journal of Gastroenterology2016，22，27： | 3 |
| 18 | Primary hepatic amyloidosis:A case report and review ofliterature显示文摘We describe a case of 42-year-old female presenting with abdominal pain associated with loss of weight and fever for 8 mo. On evaluation she had gross hepatomegaly with raised alkaline phosphatase and raised GGT levels with normal transaminases and bilirubin. On imaging she had diffuse enlargement of liver with heterogeneous contrast uptake in liver. Her viral marker and autoimmune markers were negative. Liver biopsy depicted massive deposition of amyloid in peri-sinusoidal spaces which revealed apple green birefringence on polarizing microscopy after Congo red staining. Cardiac and renal evaluation was unremarkable. Abdominal fat pad and rectum biopsy was negative for amyloid deposit. There was no evidence of primary amyloidosis as bone marrow examination was normal. Serum and urine immunofixation electrophoresis were normal. Immunoperoxidase staining for serum amyloid associated protein for secondary amyloidosis was negative from liver biopsy. We present this rare case of primary hepatic amyloidosis and review the literature regarding varied presentations of hepatic involvement in amyloidosis. | Nikhil Sonthalia Samit Jain Sunil Pawar Vinay Zanwar Ravindra Surude Praveen M Rathi | 2016 | World Journal of Hepatology2016，8，6： | 3 |
| 19 | Microwave-assisted reduction roasting–magnetic separation studies of two mineralogically different low-grade iron ores显示文摘The microwave-assisted reduction behaviours of two low-grade iron ores having a similar Fe content of 49wt%but distinctly different mineralogical and liberation characteristics were studied.Their performances in terms of the iron grade and recovery as obtained from statistically designed microwave(MW)roasting followed by low-intensity magnetic separation(LIMS)experiments were compared.At respective optimum conditions,the titano-magnetite ore(O1)could yield an iron concentrate of 62.57%Fe grade and 60.01%Fe recovery,while the goethitic ore(O2)could be upgraded to a concentrate of 64.4%Fe grade and 33.3%Fe recovery.Compared with the goethitic ore,the titanomagnetite ore responded better to MW heating.The characterization studies of the feed and roasted products obtained at different power and time conditions using X-ray diffraction,optical microscopy,vibrating-sample magnetometry,and electron-probe microanalysis explain the sequential reduction in the iron oxide phases.Finally,taking advantage of the MW absorbing character of the titano-magnetite ore,a blend of the same with the goethite-rich ore at a weight ratio of 60:40(O2:O1)was subjected to MW roasting that resulted in a concentrate of 61.57%Fe grade with a Fe recovery of 64.47%. | Subhnit K.Roy Deepak Nayak Nilima Dash Nikhil Dhawan Swagat S.Rath | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，11： | 3 |
| 20 | Recent advances in imaging technologies in dentistry显示文摘Dentistry has witnessed tremendous advances in all its branches over the past three decades. With these advances, the need for more precise diagnostic tools,specially imaging methods, have become mandatory.From the simple intra-oral periapical X-rays, advanced imaging techniques like computed tomography, cone beam computed tomography, magnetic resonance imaging and ultrasound have also found place in modern dentistry. Changing from analogue to digital radiography has not only made the process simpler and faster but also made image storage, manipulation(brightness/contrast, image cropping, etc.) and retrieval easier. The three-dimensional imaging has made the complex cranio-facial structures more accessible for examination and early and accurate diagnosis of deep seated lesions. This paper is to review current advances in imaging technology and their uses in different disciplines of dentistry. | Naseem Shah Nikhil Bansal Ajay Logani | 2014 | World Journal of Radiology2014，6，10： | 3 |
