| 1 | A gist of gastrointestinal stromal tumors: A review显示文摘Gastrointestinal stromal tumors (GISTs) have been recognized as a biologically distinctive tumor type, different from smooth muscle and neural tumors of the gastrointestinal tract (GIT). They constitute the majority of gastrointestinal mesenchymal tumors of the GIT and are known to be refractory to conventional chemotherapy or radiation. They are defined and diagnosed by the expression of a proto-oncogene protein detected by immunohistochemistry which serves as a crucial diagnostic and therapeutic target. The identification of these mutations has resulted in a better understanding of their oncogenic mechanisms. The remarkable antitumor effects of the molecular inhibitor imatinib have necessitated accurate diagnosis of GIST and their distinction from other gastrointestinal mes-enchymal tumors. Both traditional and minimally invasive surgery are used to remove these tumors with minimal morbidity and excellent perioperative outcomes. The revolutionary use of specific, molecularlytargeted therapies, such as imatinib mesylate, reduces the frequency of disease recurrence when used as an adjuvant following complete resection. Neoadjuvant treatment with these agents appears to stabilize disease in the majority of patients and may reduce the extent of surgical resection required for subsequent complete tumor removal. The important interplay between the molecular genetics of GIST and responses to targeted therapeutics serves as a model for the study of targeted therapies in other solid tumors. This review summarizes our current knowledge and recent advances regarding the histogenesis, pathology, molecular biology, the basis for the novel targeted cancer therapy and current evidence based management of these unique tumors. | Ashwin Rammohan Jeswanth Sathyanesan Kamalakannan Rajendran Anbalagan Pitchaimuthu Senthil-Kumar Perumal UP Srinivasan Ravi Ramasamy Ravichandran Palaniappan Manoharan Govindan | 2013 | World Journal of Gastrointestinal Oncology2013，5，6： | 27 |
| 2 | Role of diet in the management of inflammatory bowel disease显示文摘Many studies have looked at connections between diet,etiology,signs and symptoms associated with inflammatory bowel disease(IBD).Although these connections are apparent to clinicians,they are difficult to prove qualitatively or quantitatively.Enteral feeding and polymeric diets are equally effective at bringing about remission in Crohn's disease(CD).Parenteral feeding is also effective,although none of these methods is as effective as corticosteroid therapy.However,enteral feeding is preferred in the pediatric population because linear growth is more adequately maintained via this route.Exclusion diets in patients brought into remission using an elemental diet have been shown to maintain remission for longer periods.Studies that aim to isolate culpable food groups have shown that individuals react differently on exposure to or exclusion of various foods.The commonly identifi ed food sensitivities are cereals,milk,eggs,vegetables and citrus fruits.Studies that have looked at gut mucosal antigen behavior have shown higher rectal blood flow,in response to specifi c food antigens,in those with CD over healthy subjects.Exclusion of sugar shows little evidence of amelioration in CD.Omega 3 fatty acids show promise in the treatment of IBD but await larger randomized controlled trials.Patients frequently notice that specifi c foods cause aggravation of their symptoms.Whilst it has been diffi cult to pinpoint specifi c foods,with advances in the laboratory tests and food supplements available,the aim is to prolong remission in these patients using dietary measures,and reduce the need for pharmacotherapy and surgical intervention. | Nirooshun Rajendran Devinder Kumar | 2010 | World Journal of Gastroenterology2010，16，12： | 22 |

| 4 | Nano zinc, an alternative to conventional zinc as animal feed supplement:A review显示文摘The uniqueness of Zn is that, it is the second most abundant trace element in the animal body but can't be stored in the body, thus regular dietary intake is required. Zinc oxide(ZnO) nanoparticles(NP) particles are being extensively used in paints, skin lotions pigments, food, electronics appliances, biological and pharmaceutical applications and many more. Zinc oxide nanoparticles are the specially prepared mineral salt having particle size of 1 to 100 nm. It promotes growth can act as antibacterial agent,modulates the immunity and reproduction of the animals. Both in lower and higher doses of specifications it has exhibited a variety of effects on animal performances. Apart from being highly bioavailable, reports have already pointed out the growth promoting, antibacterial, immuno-modulatory and many more effects of nano zinc(nZn). These can be used at lower doses and can provide better result than the conventional Zn sources and indirectly prevents environmental contamination also. The toxicological studies provide mixed results in animal models. Studies been undertaken in diversified animal species and encouraging effects have been reported with nZn supplementation. However, there is a need to optimize the dose and duration of ZnO NP supplementation for human and livestock,depending on its biological effects. Actual bioavailability of ZnO NP in livestock is still to be worked out.In this review we have attempted to summarize, conclude the beneficial effects of nZnO and its possible usage as mineral supplement to different categories of human and livestock. | Partha S.Swain Somu B.N.Rao Duraisamy Rajendran George Dominic Sellappan Selvaraju | 2016 | Animal Nutrition2016，，3： | 11 |
| 5 | Evaluation of Medium Components by Plackett-Burman Statistical Design for Lipase Production by Candida rugosa and Kinetic Modeling显示文摘Lipase production by Candida rugosa was carried out in submerged fermentation.Plackett-Burman statisticalexperimental design was applied to evaluate the fermentation medium components.The effect of twelve medium components was studied in sixteen experimental trials.Glucose,olive oil,peptone and FeCl3·6H2O were found to have more significance on lipase production by Candida rugosa.Maximum lipase activity of 3.8 u mL-1 was obtained at 50h of fermentation period.The fermentation was carried out at optimized temperature of 3℃,initial pH of 6.8 and shaking speed of 120 r/min.Unstructured kinetic models were used to simulate the experimental data.Logistic model,Luedeking-Piret model and modified Luedeking-Piret model were found suitable to efficiently predict the cell mass,lipase production and glucose consumption respectively with high determination coefficient(R2).From the estimated values of the Luedeking-Piret kinetic model parameters,α and β,it was found that the lipase production by Candida rugosa is growth associated. | Aravindan Rajendran Anbumathi Palanisamy Viruthagiri Thangavelu | 2008 | 生物工程学报2008，24，3： | 9 |
| 6 | Significant increase in HBV, HCV, HIV and syphilis infections among blood donors in West Bengal, Eastern India 2004-2005: Exploratory screening reveals high frequency of occult HBV infection显示文摘AIM: To evaluate the prevalence of markers of hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immunodeficiency virus (HIV) among blood donors in Kolkata, Eastern India for two consecutive years and to conduct a pilot study to explore the presence of HBV DNA among hepatitis B surface antigen (HBsAg) negative but anti-HBc positive blood donors. METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations. | Prasun Bhattacharya Partha Kumar Chandra Sibnarayan Datta Arup Banerjee Subhashish Chakraborty Krishnan Rajendran Subir Kumar Basu Sujit Kumar Bhattacharya Runu Chakravarty | 2007 | World Journal of Gastroenterology2007，13，27： | 9 |
| 7 | Role of essential oils in food safety: Antimicrobial and antioxidant applications显示文摘Essential oils(EOs)are more complex and comprise a number of volatile and natural bioactive compounds,which often used in food industries as the best alternatives.This review focuses on the impact of EOs and the roles of their major components in food manufacturing as natural preservatives with the related mechanisms of action.In addition,the major bioactive molecules of different types of EOs and their pharmacological activities such as antioxidant,antifungal and antimicrobial effects on crop protection were also discussed.The major compounds of EOs represent potential antioxidant,antimicrobial and antifungal activities through various mechanisms.Different types of EOs such as tea tree oil,lemon oil,clove oil,cinnamon oil and thyme oil from various traditional plants,have significantly showed better antimicrobial and antioxidant activities,and also effectively increased the shelf lives of the cereal products and increased the quality of food safety.The major groups of EOs such as terpenes and aromatic volatile compounds,play a key role in food safety without affecting the quality.Due to their various activities including antioxidant and antimicrobial activities,EOs could be used as alternative preservatives to increase the shelf lives of cereals and crops. | Sundaresan Bhavaniramya Selvaraju Vishnupriya Mohammad Saleh Al-Aboody Rajendran Vijayakumar Dharmar Baskaran | 2019 | Grain & Oil Science and Technology2019，2，2： | 8 |
| 8 | Variable speed wind turbine for maximum power capture using adaptive fuzzy integral sliding mode control显示文摘This paper presents a nonlinear control approach to variable speed wind turbine(VSWT)with a wind speed estimator.The dynamics of the wind turbine(WT)is derived from single mass model.In this work,a modified Newton Raphson estimator has been considered for exact estimation of effective wind speed.The main objective of this work is to extract maximum energy from the wind at below rated wind speed while reducing drive train oscillation.In order to achieve the above objectives,VSWT should operate close to the optimal power coefficient.The generator torque is considered as the control input to achieve maximum energy capture.From the literature,it is clear that existing linear and nonlinear control techniques suffer from poor tracking of WT dynamics,increased power loss and complex control law.In addition,they are not robust with respect to input disturbances.In order to overcome the above drawbacks,adaptive fuzzy integral sliding mode control(AFISMC)is proposed for VSWT control.The proposed controller is tested with different types of disturbances and compared with other nonlinear controllers such as sliding mode control and integral sliding mode control.The result shows the better performance of AFISMC and its robustness to input disturbances.In this paper,the discontinuity in integral sliding mode controller is smoothed by using hyperbolic tangent function,and the sliding gain is adapted using a fuzzy technique which makes the controller more robust. | Saravanakumar RAJENDRAN Debashisha JENA | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，2： | 8 |
| 9 | High-risk corneal allografts: A therapeutic challenge显示文摘Corneal transplantation is the most common surgical procedure amongst solid organ transplants with a high survival rate of 86% at 1-year post-grafting. This high success rate has been attributed to the immune privilege of the eye. However, mechanisms originally thought to promote immune privilege, such as the lack of antigen presenting cells and vessels in the cornea, are challenged by recent studies. Nevertheless, the immunological and physiological features of the cornea promoting a relatively weak alloimmune response is likely responsible for the high survival rate in 'low-risk' settings. Furthermore, although corneal graft survival in 'lowrisk' recipients is favourable, the prognosis in 'high-risk' recipients for corneal graft is poor. In 'high-risk' grafts, the process of indirect allorecognition is accelerated by the enhanced innate and adaptive immune responses due to pre-existing inflammation and neovascularization of the host bed. This leads to the irreversible rejection of the allograft and ultimately graft failure. Many therapeutic measures are being tested in pre-clinical and clinical studies to counter the immunological challenge of 'high-risk' recipients. Despite the prevailing dogma, recent data suggest that tissue matching together with use of systemic immunosuppression may increase the likelihood of graft acceptance in 'high-risk' recipients. However, immunosuppressive drugs are accompanied with intolerance/side effects and toxicity, and therefore, novel cell-based therapies are in development which target host immune cells and restore immune homeostasis without significant side effect of treatment. In addition, developments in regenerative medicinemay be able to solve both important short comings of allotransplantation:(1) graft rejection and ultimate graft failure; and(2) the lack of suitable donor corneas. The advances in technology and research indicate that wider therapeutic choices for patients may be available to address the worldwide problem of corneal blindness in both 'low-risk' and 'high-risk' hosts. | Tian Yu Vijayalakshmi Rajendran May Griffith John V Forrester Lucia Kuffová | 2016 | World Journal of Transplantation2016，6，1： | 7 |
| 10 | Neuroendocrine carcinoma of the ampulla of Vater:a clinicopathologic evaluation显示文摘BACKGROUND:Only 105 cases of neuroendocrine tumor(NET)of the ampulla of Vater have been described, mostly as single case reports.The incidence of NET is rising.The changes in incidence may result from changes in detection.This study was to determine the relative incidence and clinicopathological characteristics of high- grade neuroendocrine carcinoma(small cell carcinoma and large cell carcinoma)of the ampulla of Vater at a single institution. METHODS:Sections from paraffin blocks of tumors of the ampulla of Vater taken from 45 patients who underwent Whipple's procedure and 6 patients who underwent palliative bypass between September 2003 and January 2007 were subjected to immunohistochemical analysis.The clinical and pathological data from 5 patients diagnosed with NET of the ampulla of Vater were analyzed. RESULTS:The patients were 3 men and 2 women,ranging in age from 39 to 47 years(mean 44 years).Operative procedures included Whipple's procedure in 4 patients and palliative bypass in 1 patient.Histopathological examination revealed large-cell neuroendocrine carcinoma in 2 patients,small cell carcinoma in 2,and carcinoid in 1.Three patients with high-grade neuroendocrine carcinoma who had undergone Whipple's procedure died at postoperatively 7,11,and 13 months.The patient who had undergone palliative triple bypass died 3 months after surgery.CONCLUSIONS:The relative incidence of high-grade neuroendocrine carcinomas of the ampulla of Vater is higher than that generally expected.The tumors behave aggressively and have a dismal prognosis despite aggressive treatment. | Eswaran Selvakumar Shanmugasundaram Rajendran Tirupporur Govindaswamy Balachandar Devy Gounder Kannan Satyanesan Jeswanth Palaniappan Ravichandran Rajagopal Surendran | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，4： | 7 |

| 12 | Exposure to polycyclic aromatic hydrocarbons with special focus on cancer显示文摘Polycyclie aromatic hydrocarbons(PAHs) are a group of compounds consisting of two or more fused aromatic rings.Most of them are formed during incomplete combustion of organic materials such as wood and fossil fuels,petroleum products,and coal.The composition of PAH mixtures varies with the source and is also affected by selective weathering effects in the environment.PAHs are ubiquitous pollutants frequently found in a variety of environments such as fresh water and marine sediments,the atmosphere,and ice.Due to their widespread distribution,the environmental pollution due to PAHs has aroused global concern.Many PAHs and their epoxides are highly toxic,mutagenic and/or carcinogenic to microorganisms as well as to higher forms of life including humans.The main aim of this review is to provide contemporary information on PAH sources,route of exposure,worldwide emission rate,and adverse effects on humans,especially with reference to cancer. | Thamaraiselvan Rengarajan Peramaiyan Rajendran Natarajan Nandakumar Boopathy Lokeshkumar Palaniswami Rajendran Ikuo Nishigaki | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，3： | 6 |
| 13 | Antibacterial activity of selected ethnomedicinal plants from South India显示文摘Objective:To screen the antimicrobial potential of three ethnomedicinal plants Chassalia curviflora Thw.(C.curviflora),Cyclea peltata Hook.F.& Thomson(C.peltata) and Euphorbia hirta L(E.hirta) used in folk medicines in Aarukani hills Kani tribe,Tamil Nadu,India against human bacterial pathogens.Methods:Antibacterial efficacy was performed by disc diffusion method against the pathogens viz.,Escherichia coli(E.coli)(ATCC 35218),Staphylococcus aureus (S.aureus)(ATCC 6538),Salmonella typhi(S.typhi)(MTCC 733),Proteus vulgaris(P.vulgaris), Proteus mirabilis(P.mirabilis) and Streptococcus pyogenes(S.pyogenes) and incubated for 24 h at 37°C.Results:The maximum degree of antibacterial activity was observed in C.peltata followed by C.curviflora.While E.hirta showed comparatively low degree of antibacterial activity.The methanolic extract of C.peltata showed the antibacterial activity against three pathogens viz.,S.pyogenes,P.vulgaris and E.coli with the inhibition zones 12 mm,10 mm and 9 mm,respectively,hexane extracts of C.peltata also showed the antibacterial activity against two selected pathogens viz.,P.vulgaris and P.mirabilis with 15 mm and 12 mm of inhibition zones.All the three different concentrations(025,0.50 & 0.75 mg/mL) of methanolic extract of C. peltata show the inhibitory effect on the three susceptible bacteria S.pyogenes,P.vulgaris and E. coli with the maximum inhibition in the highest concentration(0.75 mg/mL).The methanolic and hexane extracts of C.curviflora exhibited the antibacterial activity against only one bacterium each i.e.P.vulgaris and S.typhi with the maximum zone of inhibition 13 and 11 mm respectively. The methanolic and hexane extracts of E.hirta exhibited the antibacterial activity against only one bacterium Le.S.pyogenes with the maximum zone of inhibition 13 and 11 mm respectively. Conclusions:The present investigation revealed that the C.curviflora,C.peltata and E.hirta are potentially good source of antibacterial agents and demonstrates the importance of such plants in traditional medicines. | Rajendran Darling Anpin Raja Solomon Jeeva Juststella Wilfred Prakash Johnson Marimuthu Antonisamy Varaprasadham Irudayaraj | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，5： | 6 |
| 14 | Long-term outcome of gastric access loop in hepaticojejunostomy显示文摘BACKGROUND:The incidence of hepaticojejunostomy stricture is 4%-10% in experienced centres. Many access loops have been designed and used to facilitate endoscopic intervention for this complication of hepaticojejunostomy. In this study, we investigated the effectiveness and safety of gastric access loop. METHODS:A retrospective analysis was conducted on 13 patients who had undergone hepaticojejunostomy with gastric access loop between June 1999 and September 2003. Eleven patients were followed up for a mean period of 51 months (range 20-81 months). Two patients were lost to follow up. RESULTS:On follow-up, 8 patients had patent jejuno- gastrostomy (end to side anastomosis between Roux loop of jejunum and stomach) and hepaticojejunostomy. Three patients developed stricture of jejunogastrostomy at 41 months, 63 months and 81 months of follow-up. Among these 3 patients, one also had hepaticojejunostomy stricture. In the patient with hepaticojejunostomy stricture, dilatation of jejunogastrostomy stricture was attempted but failed. None of the patients had any evidence of bile gastritis/cholangitis. There was no procedure related morbidity/mortality. CONCLUSIONS:Further studies involving large numbers of patients are required before wide application of gastric access loop in hepaticojejunostomy though it is a safer option than percutaneous transhepatic manipulations or revision surgery. | Eswaran Selvakumar Shanmugasundaram Rajendran Tirupporur G.

| 19 | Sol-Gel Coating with 3-Mercaptopropyltrimethoxysilane as Precursor for Corrosion Protection of Aluminium Metal显示文摘Sol—gel coatings offer a number of advantages over other methods of protection for metallic materials.In the present work,3-mercaptopropyltrimethoxysilane(MPTS) was used as the precursor for sol—gel coating on aluminium metal.The gelation of MPTS sol—gel was characterized by Fourier transform infrared spectroscopy(FT-IR) studies.The formed film was found to be stable up to 350 ℃ as evident from thermogravimetric analysis.X-ray diffraction study and scanning electron microscopy supported the formation of MPTS coating on aluminium surface while the characterization of the coating was done by FT-IR studies.The corrosion inhibition potential of the sol—gel coatings on metal in 3.5%(w/v) of NaCI solution was assessed as a function of different concentrations of MPTS using electrochemical polarization and impedance measurements.The corrosion inhibition efficiency was found to increase with increasing MPTS concentration.The results of the study unravel the use of MPTS as a precursor in the formation of sol—gel coating over aluminium surface so as to protect the metallic surface from corrosion in neutral environment. | Rajendran Babhu Vignesh Thomas Nesakumar Jebakumar Immanuel Edison Mathur Gopalakrishnan Sethuraman | 2014 | Journal of Materials Science & Technology2014，30，8： | 4 |
| 20 | Backstepping sliding mode control of a variable speed wind turbine for power optimization显示文摘To optimize the energy capture from the wind,wind turbine(WT)should operate at variable speed.Based on the wind speed,the operating regions of the WT are divided into two parts:below and above the rated wind speed.The main aim at below rated wind speed is to maximize the energy capture from the wind with reduced oscillation on the drive train.At above rated wind speed,the aim is to maintain the rated power by using pitch control.This paper presents the control of WT at below rated wind speed by using backstepping sliding mode control(BSMC).In BSMC,generator torque is considered as the control input that depends on the optimal rotor speed.Usually,this optimal rotor speed is derived from effective wind speed.In this paper,effective wind speed is estimated from aerodynamic torque and rotor speed by using the modified Newton Rapshon(MNR)algorithm.Initially,a conventional sliding mode controller(SMC)is applied to the WT,but the performance of the controller was found to be less robust with respect to disturbances.Generally,WT external disturbance is not predictable.To overcome the above drawback,BSMC is proposed and both the controllers are tested with mathematical model and finally validated with the fatigue,aerodynamics,structures,and turbulence(FAST)WT simulator in the presence of disturbances.From the results,it is concluded that the proposed BSMC is more robust than conventional SMC in the presence of disturbances. | Saravanakumar RAJENDRAN Debashisha JENA | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，3： | 3 |
