| 1 | Hepatocellular carcinoma: From diagnosis to treatment显示文摘Hepatocellular carcinoma(HCC) is the sixth most prevalent malignancy worldwide and is a rising cause of cancer related mortality. Risk factors for HCC are well documented and effective surveillance and early diagnosis allow for curative therapies. The majority of HCC appears to be caused by cirrhosis from chronic hepatitis B and hepatitis C virus. Preventive strategies include vaccination programs and anti-viral treatments.Surveillance with ultrasonography detects early stage disease and improves survival rates. Many treatment options exist for individuals with HCC and are determined by stage of presentation. Liver transplantation is offered to patients who are within the Milan criteria and are not candidates for hepatic resection. In patients with advanced stage disease, sorafenib shows some survival benefit. | Abhijeet Waghray Arvind R Murali KV Narayanan Menon | 2015 | World Journal of Hepatology2015，7，8： | 27 |
| 2 | Evolution,current status and advances in application of platelet concentrate in periodontics and implantology显示文摘Platelet concentrates(PC) [platelet-rich plasma(PRP) and platelet-rich fibrin(PRF)] are frequently used for surgical procedures in medical and dental fields,particularly in oral and maxillofacial surgery,plastic surgery and sports medicine.The objective of all these technologies is to extract all the elements from a blood sample that could be used to improve healing and promote tissue regeneration.Although leukocyte rich and leukocyte poor PRP's have their own place in literature,the importance of non-platelet components in a platelet concentrate remains a mystery.PC have come a long way since its first appearance in 1954 to the T-PRF,A-PRF and i-PRF introduced recently.These PC find varied applications successfully in periodontics and implant dentistry as well.However,the technique of preparation,standing time,transfer process,temperature of centrifuge,vibration,etc.,are the various factors for the mixed results reported in the literature.Until the introduction of a proper classification of terminologies,the PC were known by different names in different countries and by different commercial companies which also created a lot of confusion.This review intends to clarify all these confusion by briefing the exact evolution of PC,their preparation techniques,recent advances and their various clinical and technical aspects and applications. | Amit Arvind Agrawal | 2017 | World Journal of Clinical Cases2017，5，5： | 28 |

| 4 | 剖宫产子宫切口瘢痕缺陷的宫腔镜手术治疗显示文摘剖宫产瘢痕憩室(CSD)是剖宫产术后远期并发症之一,CSD实际上是剖宫产子宫切口愈合不良所致,其形成的原因比较复杂。关于CSD有不少认识上的误区,对于没有症状的CSD一般不需要治疗,对于有症状的CSD如何治疗在认识上也比较混乱,如何选择合适的治疗方式不仅关系到医务人员对于CSD的认识也直接影响了CSD的治疗效果。有一种特殊类型的CSD是切口瘢痕下缘存在活瓣作用且由于活瓣作用而阻止了憩室内的经血顺利流出而出现症状(常见为经期延长),同时憩室内的异位子宫内膜也可能与宫腔内在位的内膜生长不同步也导致异常阴道流血,这种特殊的CSD学术界有个专业的名称即剖宫产子宫切口瘢痕缺陷(PCSD)。对于残余子宫壁肌层不是很薄的PCSD,可以采用宫腔镜手术切除活瓣并电凝破坏憩室内异位子宫内膜的治疗方法。而对于没有PCSD特点的CSD,宫腔镜手术的疗效较差,一般不采用宫腔镜手术治疗。文章将深入阐述PCSD的宫腔镜手术治疗的相关问题。 | 李旺 邹凌霄 潘琼 覃娴 Arvind Burjoo 万亚军 徐大宝 | 2018 | 中国实用妇科与产科杂志2018，34，8： | 14 |
| 5 | Contemporary role of multi-tract percutaneous nephrolithotomy in the treatment of complex renal calculi显示文摘Complex renal calculi remain to be a challenge for the treating urologist due to sheer bulk and the technicalities involved.Percutaneous nephrolithotomy(PCNL)remains the treatment modality of choice in dealing with these large and complex stones.The limiting factor in their treatment continues to be the need for using additional tracts or the use of flexible nephroscopy for complete stone clearance.This systematic review focuses on the need for multi-tract PCNL for complex renal calculi.The literature review was performed using PubMed database using the keywords“multiple tract PCNL”or“multiperc”.We identified original articles published on the usage of multiple tracts for stone clearance in renal calculi between January 2000 to October 2018,and the search was restricted to available literature in English language only.Ten studies with n>20 were included for the final analysis.We analyzed the technical efficacy with respect to the number of tracts and stages that were required for stone clearance,outcomes and complications,especially,procedural bleeding and post-procedure infective complications of multiple-tract PCNL for large burden renal stones.Multiperc is found to be safe,feasible and effective for the management of large burden complex renal calculi with respect to stone clearance and morbidity associated with the procedure.It is cost effective and complete stone clearance as a single procedure is higher in comparison to flexible ureteroscopy and shockwave lithotripsy. | Sudharsan Balaji Arvind Ganpule Thomas Herrmann Ravindra Sabnis Mahesh Desai | 2020 | Asian Journal of Urology2020，7，2： | 11 |
| 6 | Chronic hepatitis E: A brief review显示文摘Hepatitis E viral infection has traditionally been considered an acute, self-limited, water borne disease similar to hepatitis A, endemic to developing countries. However, over the past decade, zoonotic transmission and progression to chronicity in human patients has been identified, resulting in persistently elevated transaminase levels, progressive liver injury and cirrhosis. In addition to liver injury, neurological, renal and rheumatological manifestations have also been reported. Chronic hepatitis E occurs mainly in immunosuppressed individuals such as transplant recipients, human immunodeficiency virus patients with low CD4 counts and in patients with hematological malignancies receiving chemotherapy. Diagnosis is established by persistent elevation of hepatitis E virus RNA in the stool or serum. This population often requires treatment with antiviral agents, particularly ribavirin, as spontaneous clearance with reduction in immunosuppression occurs only in about a third of the patients. The purpose of this review, is to further discuss the clinical presentation, and recent advances in diagnosis, treatment and prophylaxis of chronic hepatitis E. | Arvind R Murali Vikram Kotwal Saurabh Chawla | 2015 | World Journal of Hepatology2015，7，19： | 9 |
| 7 | Underground mining of thick coal seams显示文摘This paper reviews underground mining methods for total thickness of a thick coal seam in single lift(TTTCSSL). Review shows the required engineering for extraction of thick seams needs to be fitted with thickness of the seam, behavior of rock-mass and surrounding stress conditions for efficient mining.Variants of TTTCSSL are able to extract a maximum 10–12 m thickness only. An improvement in bending moment of the overlying coal band in longwall top coal caving(LTCC) provides better under-winning opportunity for the roof coal band. An acceptable limit of 25 MPa compressive strength of coal for the success of LTCC may be increased under favorable geo-technical conditions. Bord and pillar in India adopted induced caving of roof coal band for single lift depillaring of total thickness(SLDTT) of a competent thick coal seam developed along floor. Case studies are given to arrest the adverse effects of extraction height on pillars. | Kumar Rakesh Singh Arun Kumar Mishra Arvind Kumar Singh Rajendra | 2015 | International Journal of Mining Science and Technology2015，25，6： | 7 |

| 9 | Optimisation of Adventitious Shoot Regeneration and Agrobacterium-mediated Transformation in Canna × generalis(Canna Lily)显示文摘Canna being ornamental plants has a significant role in agriculture, medical, economy and food industry. Canna has a limited vase life due to the rapid loss of moisture from its perianth. For improving its market value, cuticularisation of the perianth can be achieved by the expression of a heterologous cutin producing gene, using the tissue culture and transformation protocol developed in this study. Efficient, rapid and direct adventitious shoot regeneration was successfully established in Canna × generalis using recalcitrant rhizome explants. The explants were cultured on MS medium supplemented with 6-benzylaminopurine(6-BA), thidiazuron(TDZ), and kinetin. Among the four genotypes taken for tissue culture, the ‘Trinacria variegata' was the best responding cultivar. And 2 mg · L^(-1)6-BA or 1.5 mg · L^(-1) TDZ along with 0.1 mg · L^(-1) IAA was optimum for their regeneration. The highest regeneration was achieved in ‘Trinacria variegata'(36%) on 6-BA, 33% on TDZ while kinetin failed to evoke any regenerative responses. Regeneration was enhanced by supplementation of 100 mg · L^(-1) ascorbic acid(AsA), while, 100 mg · L^(-1) of l-cysteine or 100 mg · L^(-1) dithiothreitol(DTT), inhibited regeneration. Shoots were observed to develop 3–5 fibrous roots on MS medium supplemented with 0.5 mg · L^(-1) indole-3-butyric acid(IBA). The plantlets were transplanted into pots and acclimatised in glasshouse with 100%survival. For transformation of Canna, rhizome explants were co-cultivated for 60 min in Agrobacterium suspension. The explants were washed with 500 mg · L^(-1) cefotaxime solution, subjected to 100 mg · L^(-1) kanamycin selection followed by excision of the shoots and culturing them on IBA-supplemented media for root development. Transgene integration in the putative transformants was confirmed by PCR assay and copy number by Southern blot hybridisation analysis. | Rani Singh Arvind Kumar Dubey Indraneel Sanyal | 2019 | Horticultural Plant Journal2019，5，1： | 6 |
| 10 | Gingival enlargements: Differential diagnosis and review of literature显示文摘Gingival enlargement is one of the frequent features of gingival diseases. However due to their varied presentations, the diagnosis of these entities becomes challenging for the clinician. They can be categorized based on their etiopathogenesis, location, size, extent, etc. Based on the existing knowledge and clinical experience, a differential diagnosis can be formulated. Subsequently, after detailed investigation, clinician makes a final diagnosis or diagnosis of exclusion. A perfect diagnosis is critically important, since the management of these lesions and prevention of their recurrence is completely dependent on it. Furthermore, in some cases where gingival enlargement could be the primary sign of potentially lethal systemic diseases, a correct diagnosis of these enlargements could prove life saving for the patient or at least initiate early treatment and improve the quality of life. The purpose of this review article is to highlight significant findings of different types of gingival enlargement which would help clinician to differentiate between them. A detailed decision tree is also designed for the practitioners, which will help them arrive at a diagnosis in a systematic manner. There still could be some lesions which may present in an unusual manner and make the diagnosis challenging. By knowing the existence of common and rare presentations of gingival enlargement, one can keep a broad view when formulating a differential diagnosis of localized(isolated, discrete, regional) or generalized gingival enlargement. | Amit Arvind Agrawal | 2015 | World Journal of Clinical Cases2015，3，9： | 6 |
| 11 | Analyses of Lattice Traffic Flow Model on a Gradient Highway显示文摘The optimal current difference lattice hydrodynamic model is extended to investigate the traffic flow dynamics on a unidirectional single lane gradient highway. The effect of slope on uphill/downhill highway is examined through linear stability analysis and shown that the slope significantly affects the stability region on the phase diagram.Using nonlinear stability analysis, the Burgers, Korteweg-deVries(KdV) and modified Korteweg-deVries(mKdV) equations are derived in stable, metastable and unstable region, respectively. The effect of reaction coefficient is examined and concluded that it plays an important role in suppressing the traffic jams on a gradient highway. The theoretical findings have been verified through numerical simulation which confirm that the slope on a gradient highway significantly influence the traffic dynamics and traffic jam can be suppressed efficiently by considering the optimal current difference effect in the new lattice model. | Arvind Kumar Gupta Sapna Sharma Poonam Redhu | 2014 | Communications in Theoretical Physics2014，61，9： | 5 |
| 12 | Bilateral vs unilateral placement of metal stents for inoperable highgrade hilar biliary strictures: A systemic review and meta-analysis显示文摘BACKGROUND Bilateral vs unilateral biliary stenting is used for palliation in malignant biliary obstruction.No clear data is available to compare the efficacy and safety of bilateral biliary stenting over unilateral stenting.AIM To assess the efficacy and safety of bilateral vs unilateral biliary drainage in inoperable malignant hilar obstruction.METHODS PubMed,Embase,Scopus,and Cochrane databases,as well as secondary sources(bibliographic review of selected articles and major GI proceedings),were searched through January 2019.The primary outcome was the re-intervention rate.Secondary outcomes were a technical success,early and late complications,and stent malfunction rate.Pooled odds ratio(OR)and 95%confidence interval(CI)were calculated for each outcome.RESULTS A total of 9 studies were included(2 prospective Randomized Controlled Study,5 retrospective studies,and 2 abstracts),involving 782 patients with malignant hilar obstruction.Bilateral stenting had significantly lower re-intervention rate compared with unilateral drainage(OR=0.59,95%CI:0.40-0.87,P=0.009).There was no difference in the technical success rate(OR=0.7,CI:0.42-1.17,P=0.17),early complication rate(OR=1.56,CI:0.31-7.75,P=0.59),late complication rate(OR=0.91,CI:0.58-1.41,P=0.56)and stent malfunction(OR=0.69,CI:0.42-1.12,P=0.14)between bilateral and unilateral stenting for malignant hilar biliary strictures.CONCLUSION Bilateral biliary drainage had a lower re-intervention rate as compared to unilateral drainage for high grade inoperable malignant biliary strictures,with no significant difference in technical success,and early or late complication rates. | Munish Ashat Sumant Arora Jagpal S Klair Christopher A Childs Arvind R Murali Frederick C Johlin | 2019 | World Journal of Gastroenterology2019，25，34： | 5 |
| 13 | Muscle RING-finger protein-1 (MuRFl) functions and cellular localization are regulated by SUMOl post-translational modification显示文摘The muscle RING-finger protein-1 (MuRFl) is an E3 ubiquitin ligase expressed in skeletal and cardiac muscle tissues and it plays important roles in muscle remodeling. Upregulation of MuRFl gene transcription participates in skeletal muscle atrophy, on contrary downregulation of protein expression leads to cardiac hypertrophy. MuRFl gene point mutations have been found to generate protein aggregate myopathies defined as muscle disorder characterized by protein accumulation in muscle fibers. We have discovered that MuRFl turned out to be also a target for a new post-translational modification arbitrated by conjugation of SUM01 and it is mediated by the SUMO ligases E2 UBC9 and the E3 PIASy/4. SUMOylation takes place at lysine 238 localized at the second coiled-coil protein domain that is required for efficient substrate interaction for polyubiquitination. We provided evidence that SUMOylation is essential for MuRFl nuclear translocation and its mitochondria accumulation is enhanced in hyper? glycemic conditions delivering a stabilization of the overall SUMOylated proteins in cultured myocytes. Thus, our findings add this SUM01 post-translational modification as a new concept to understand muscle disorders related to the defect in MuRFl activity. | Gabriel Heras Arvind Venkat Namuduri Leonardo Traini Ganna Shevchenko Alexander Falk Sara Bergstrom Lind Mi Jia Geng Tian Stefano Gastaldello | 2019 | Journal of Molecular Cell Biology2019，11，5： | 4 |
| 14 | Soil organic carbon and phosphorus availability regulate abundance of culturable phosphate-solubilizing bacteria in paddy fields显示文摘Low availability of phosphorus(P) is a major constraint for optimal crop production, as P is mostly present in its insoluble form in soil. Therefore,phosphate-solubilizing bacteria(PSB) from paddy field soils of the Indo-Gangetic Plain, India were isolated, and their abundance was attempted to be correlated with the physicochemical characteristics of the soils. Ninety-four PSB were isolated on Pikovskaya’s agar medium, and quantitative phosphate solubilization was evaluated using NBRIP medium. The isolates solubilized P up to a concentration of 1 006 μg mL-1 from tricalcium phosphate with the secretion of organic acids. These isolates were identified by 16 S rRNA gene sequence comparison, and they belonged to Gammaproteobacteria(56 isolates),Firmicutes(28 isolates), Actinobacteria(8 isolates), and Alphaproteobacteria(2 isolates). Phylogenetic analysis confirmed the identification by clustering the isolates in the clade of the respective reference organisms. The correlation analysis between PSB abundance and physicochemical characteristics revealed that the PSB population increased with increasing levels of soil organic carbon, insoluble P, K+, and Mg2+. The promising PSB explored in this study can be further evaluated for their biofertilizer potential in the field and for their use as potent bio-inoculants. | Arvind KUMAR Lal Chand RAI | 2020 | Pedosphere2020，30，3： | 4 |
| 15 | Carcinogenic Helicobacter pylori in gastric pre-cancer and cancer lesions: Association with tobacco-chewing显示文摘AIM:To investigate the low gastric cancer incidence rate relative to the highly prevalent Helicobacter pylori(H.pylori)infection;data relevant to H.pylori infection during gastric carcinogenesis in Indian patients is currently lacking.METHODS:The present study examines the prevalence of H.pylori infection in DNA derived from 156endoscopic gastric biopsies of different disease groups that represent gastric pre-cancer[intestinal metaplasia(n=15),dysplasia(n=15)],cancer[diffuse adenocarcinoma(n=44),intestinal adenocarcinoma(n=21)],and symptomatic but histopathologically-normal controls(n=61).This was done by generic ureC polymerase chain reaction(PCR)and cagA-specific PCR that could specifically identify the carcinogenic H.pylori strain.RESULTS:Our analysis showed the presence of H.pylori infection in 61%of symptomatic histopathologically-normal individuals,however only 34%of control tissues were harboring the cagA+H.pylori strain.A similar proportion of H.pylori infection(52%)and cagA(26%)positivity was observed in the tumor tissue of the gastric cancer group.In comparison,H.pylori infection(90%)and cagA positivity(73%)were the highest in gastric pre-cancer lesions.In relation to tobacco and alcohol abuse,H.pylori infection showed an association with tobacco chewing,whereas we did not observe any association between tobacco smoking or alcohol abuse with prevalence of H.pylori infection in the tissue of any of the patient groups studied.CONCLUSION:High incidence of H.pylori infection and carcinogenic cagA positive strain in pre-cancer lesions during gastric carcinogenesis may be | Arvind Pandey Satyendra Chandra Tripathi Sutapa Mahata Kanchan Vishnoi Shirish Shukla Sri Prakash Misra Vatsala Misra Suresh Hedau Ravi Mehrotra Manisha DwivediZ Alok C Bharti | 2014 | World Journal of Gastroenterology2014，20，22： | 4 |

| 17 | Gastric conduit perforation显示文摘As patients with carcinoma of the esophagus live longer, complications associated with the use of a gastric conduit are increasing. Ulcers form in the gastric conduit in 6.6% to 19.4% of patients. There are a few reports of perforation of a gastric conduit in the English literature. Almost all of these were associated with serious complications. We report a patient who developed a tension pneumothorax consequent to spontaneous perforation of an ulcer in the gastric conduit 7 years after the index surgery in a patient with carcinoma of the gastroesophageal junction. He responded well to conservative management. Complications related to a gastric conduit can be because of multiple factors. Periodic endoscopic surveillance of gastric conduits should be considered as these are at a higher risk of ulcer formation than a normal stomach. Long term treatment with proton pump inhibitors may decrease complications. There are no guidelines for the treatment of a perforated gastric conduit ulcer and the management should be individualized. | Nilesh Patil Arvind Kaushal Amit Jain Sundeep Singh Saluja Pramod Kumar Mishra | 2014 | World Journal of Clinical Cases2014，2，8： | 4 |
| 18 | Assessment of biomass and net primary productivity of a dry tropical forest using geospatial technology显示文摘This study quantifies biomass, aboveground and belowground net productivity, along with additional environmental factors over a 2-3 year period in Barnawapara Sanctuary of Chhattisgarh, India through satellite remotesensing and GIS techniques. Ten sampling quadrates20×20, 5×5 and 1×1 m were randomly laid for overstorey (OS), understorey (US) and ground vegetation(GS), respectively. Girth of trees was measured at breast height and collar diameters of shrubs and herbs at 0.1 m height. Biomass was estimated using allometric regression equations and herb biomass by harvesting. Net primary productivity (NPP) was determined by Ssumming biomass increment and litter crop values. Aspect and slope influenced the vegetation types, biomass and NPP in different forests. Standing biomass and NPP varied from 18.6 to101.5 Mg ha^(-1) and 5.3 to 12.7 Mg ha^(-1) a^(-1), respectively,in different forest types. The highest biomass was found in dense mixed forest, while net production recoded in Teak forests. Both were lowest in degraded mixed forests of different forest types. OS, US and GS contributed 90.4, 8.7and 0.7%, respectively, for the total mean standing biomass in different forests. This study developed spectral models for the estimation of biomass and NPP using Normalized Difference Vegetation Index and other vegetation indices.The study demonstrated the potential of geospatial tools for estimation of biomass and net productivity of dry tropical forest ecosystem. | Tarun Kumar Thakur S.L.Swamy Arvind Bijalwan Mammohan J.R.Dobriyal | 2019 | Journal of Forestry Research2019，30，1： | 4 |

| 20 | 在糖尿病的 nephropathy 吸烟: 在燃料坦克的火花吗?显示文摘 Diabetic nephropathy is associated with high morbidity and mortality and the prevalence of this disease is continuously increasing worldwide.Long-term diabetes increases the likelihood of developing secondary complications like nephropathy,the most common cause of end stage renal disease.Usually,other factors like hypertension,alcoholism and smoking also partly contribute to the progression of diabetic nephropathy.Among this,cigarette smoking in diabetes has been repeatedly confirmed as an independent risk factor for the onset and progression of diabetic nephropathy.Various studies suggest that smoking is a major fuel in the development of high oxidative stress and subsequently hyperlipidemia,accumulation of advanced glycation end products,activation of the renin angiotensin system and Rho-kinase,which are observed to play a pathogenic role in the progression of diabetic nephropathy.Furthermore,cigarette smoking in diabetic patients with vascular complications produces a variety of pathological changes in the kidney,such as thickening of the glomerular basement membrane and mesangial expansion with progression in glomerulosclerosis and interstitial fibrosis,which ultimately results in end stage renal failure.Strong associations are consistently found between chronic cigarette smoking and diabetic microvascular complications.A diverse group of studies unveil potentialmechanisms that may explain the role of cigarette smoking in the progression of diabetic nephropathy.Tremendous efforts are being made to control smoking mediated progression of diabetic nephropathy,but no promising therapy is yet available.The present review critically discusses the possible detrimental role of chronic cigarette smoking in the progression of diabetic nephropathy and various possible pharmacological interventions to attenuate the exacerbation of diabetic nephropathy. | Vishal Arvind Chakkarwar | 2012 | World Journal of Diabetes2012，3，12： | 4 |
