| 1 | Choice of wound care in diabetic foot ulcer: A practical approach显示文摘Diabetic foot ulcers are the consequence of multiple factors including peripheral neuropathy,decreased blood supply,high plantar pressures,etc.,and pose a significant risk for morbidity,limb loss and mortality.The critical aspects of the wound healing mechanism and host physiological status in patients with diabetes necessitate the selection of an appropriate treatment strategy based on the complexity and type of wound.In addition to systemic antibiotics and surgical intervention,wound care is considered to be an important component of diabetic foot ulcer management.This article will focus on the use of different wound care materials in diabetic foot.From a clinical perspective,it is important to decide on the wound care material depending on the type and grade of the ulcer.This article will also provide clinicians with a simple approach to the choice of wound care materials in diabetic foot ulcer. | Karakkattu Vijayan Kavitha Shalbha Tiwari Vedavati Bharat Purandare Sudam Khedkar Shilpa Sameer Bhosale Ambika Gopalakrishnan Unnikrishnan | 2014 | World Journal of Diabetes2014，5，4： | 20 |
| 2 | Heme oxygenase-1 as a therapeutic target in inflammatory disorders of the gastrointestinal tract显示文摘Heme oxygenase (HO)-1 is the inducible isoform of the first and rate-limiting enzyme of heme degradation. HO-1 not only protects against oxidative stress and apoptosis, but has received a great deal of attention in recent years because ofits potent anti-inflammatory functions. Studies with HO-1 knockout animal models have led to major advances in the understanding of how HO-1 might regulate inflammatory immune responses, although little is known on the underlying mechanisms. Due to its beneficial effects the targeted induction of this enzyme is considered to have major therapeutic po- tential for the treatment ofinflammatory disorders. This review discusses current knowledge on the mechanisms that mediate anti-inflammatory protection by HO-1. More specifically, the article deals with the role of HO-1 in the pathophysiology of viral hepatitis, inflammatorybowel disease, and pancreatitis. The effects of specific HO-1 modulation as a potential therapeutic strategy in experimental cell culture and animal models of these gastrointestinal disorders are summarized. In conclusion, targeted regulation of HO-1 holds major promise for future clinical interventions in inflammatory diseases of the gastrointestinal tract. | Vijith Vijayan Sebastian Mueller Eveline Baumgart-Vogt Stephan Immenschuh | 2010 | World Journal of Gastroenterology2010，16，25： | 13 |
| 3 | Increased plasma malondialdehyde and fructosamine in anemic H pylori infected patients:Effect of treatment显示文摘AIM: To unravel the possible association of malon-dialdehyde (MDA) and fructosamine in anemic H pylori infected patients and to observe the alteration in MDA and fructosamine levels in these patients after treatment for one month.METHODS: Fructosamine, MDA and glucose were estimated in 22 anemic H pylori infected patients and 16 healthy controls. Hematological parameters were also evaluated in both the groups using Sysmex-K-100 automated cell counter. The H pylori infected patients were randomly divided into two groups. H pylori infected patients in GroupⅠreceived both iron supplementation and anti-H pylori therapy, while patients in Group Ⅱ received only iron supplementation. All the biochemical and hematological parameters were estimated after one month of treatment. RESULTS: In anemic H pylori infected patients, while MDA (5.41 ± 2.16 vs 2.26 ± 0.50; P < 0.05) and fructosamine (2.64 ± 0.93 vs 1.60 ± 0.35; P < 0.05) were significantly increased, iron (32.72 ± 14.93 vs 110.25 ± 26.58; P < 0.05), hemoglobin (6.9 ± 2.6 vs 12.66 ± 0.74; P < 0.05) and ferritin (28.82 ± 16.27 vs 140.43 ± 30.72; P < 0.05) levels were significantly decreased compared with the controls. With partial correlation analysis, fructosamine was found to have a significant positive correlation with MDA. In GroupⅠ, while MDA level decreased significantly (3.11 ± 1.73 vs 5.50 ± 2.46; P < 0.05), there was a significant increase in iron (84.09 ± 29.51 vs 36.09 ± 17.81; P < 0.05), hemoglobin (10.40 ± 1.11 vs 7.42 ± 1.90; P < 0.05) and ferritin (116.91 ± 63.34 vs 30.46 ± 17.81; P < 0.05) levels after one month. There was no significant change in the levels of fructosamine in groupⅠafter treatment. Similarly, no significant alterations were noted in the levels of MDA, fructosamine, hemoglobin or ferritin in Group Ⅱ patients after one month of treatment.CONCLUSION: An increased level of fructosamine and MDA was found in anemic H pylori infected patients. Present data supports the premise that lipid peroxides per se do play a role in the glycation of plasma proteins. Furthermore, the findings from this study indicate that treatment for both anemia and H pylori infections is required for lowering the levels of lipid peroxides in these patients. | G Vijayan RC Sundaram Zachariah Bobby Abdoul Hamide N Selvaraj N Rattina Dasse | 2007 | World Journal of Gastroenterology2007，13，5： | 4 |
| 4 | Prediction of oil-water flow patterns, radial distribution of volume fraction, pressure and velocity during separated flows in horizontal pipe显示文摘Flow of two immiscible fluids gives rise to variety of flow patterns,which influence transportation process.In this work,we present detailed analysis on the prediction of flow pattern maps and radial distribution of volume fraction,pressure and velocity of a pair of immiscible liquids through a horizontal pipeline by computational fluid dynamics(CFD) simulation using ANSYS FLUENT 6.3.Moderately viscous oil and water have been taken as the fluid pair for study.Volume of fluid(VOF) method has been employed to predict various flow patterns by assuming unsteady flow,immiscible liquid pair,constant liquid properties,and co-axial flow.From the grid independent study,we have selected 47 037 number of quadrilateral mesh elements for the entire geometry.Simulation successfully predicts almost all the flow patterns(viz.,plug,slug,stratified wavy,stratified mixed and annular),except dispersion of oil in water and dispersion of water in oil.The simulated results are validated with experimental results of oil volume fraction and flow pattern map.Radial distribution of volume fraction,pressure and velocity profiles describe the nature of the stratified wavy,stratified mixed and annular flow pattern.These profiles help to developing the phenomenological correlations of interfacial characteristics in two-phase flow. | Anand B.DESAMALA Vinayak VIJAYAN Anjali DASARI Ashok Kumar DASMAHAPATRA Tapas K.MANDAL | 2016 | Journal of Hydrodynamics2016，28，4： | 3 |
| 5 | Hidden Two-Stream Collaborative Learning Network for Action Recognition显示文摘The two-stream convolutional neural network exhibits excellent performance in the video action recognition.The crux of the matter is to use the frames already clipped by the videos and the optical flow images pre-extracted by the frames,to train a model each,and to finally integrate the outputs of the two models.Nevertheless,the reliance on the pre-extraction of the optical flow impedes the efficiency of action recognition,and the temporal and the spatial streams are just simply fused at the ends,with one stream failing and the other stream succeeding.We propose a novel hidden two-stream collaborative(HTSC)learning network that masks the steps of extracting the optical flow in the network and greatly speeds up the action recognition.Based on the two-stream method,the two-stream collaborative learning model captures the interaction of the temporal and spatial features to greatly enhance the accuracy of recognition.Our proposed method is highly capable of achieving the balance of efficiency and precision on large-scale video action recognition datasets. | Shuren Zhou Le Chen Vijayan Sugumaran | 2020 | Computers, Materials & Continua2020，，6： | 3 |
| 6 | Evaluation of phenolic contents and antioxidant activities of brown seaweeds belonging to Turbinaria spp.(Phaeophyta,Sargassaceae) collected from Gulf of Mannar显示文摘Objective:To evaluate the antioxidant activities and total phenolic contents of brown seaweeds belonging to Turbinaria spp.[Turbinaria conoides(T.conoides)and Turbinaria ornata(T.ornata)collected from Gulf of Mannar of southeastern coast of India in various in vitro systems.Methods:The antioxidant activity was evaluated using different in vitro systems,viz.,I,I-diphenyl-2-picrylhydrazyl(DPPH),2,2'-azino-bis-3 ethylbenzothiozoline-6-sulfonic acid diammonium salt(ABTS),H_20_2/H0 radical scavenging,Fe^(2+)ion chelating ability,and reducing potential.Folin-Ciocalteu method was used to determine the total phenolic content of the extracts,and the results were expressed as mg of gallic acid equivalents(GE)/g of the seaweed extracts.Thiobarbituric acid-reactive substances assay was employed to assess the ability of the seaweed extracts to inhibit lipid oxidation.Results:Ethyl acetate(EtOAc)fraction of T.conoides registered significantly higher phenolic content(105.97 mg GE/g)than that of T.ornata(69.63 mg GE/g).Significantly higher antioxidant potential as determined by DPPH(64.14%)radical scavenging activity was registered in EtOAc fraction of T.ornata.A higher ABTS(?)radical scavenging(IC_(50)3.16μg/mL),Fe^(2+)chelating(IC_(50)0.46 mg/mL),H_2O_2 scavenging(IC_(50)4.25 mg/mL),lipid peroxidation inhibitory(TBARS,IC_(50)0.21 mg/mL),and reducing abilities(IC_(50)52.67 mg/mL)(P<0.05)were realized in EtOAc fraction of T.ornata than other fractions.Conclusions:This study indicated the potential use of T.conoides and T.ornata as candidate species to be used as food supplements/functional foods to increase shelf-life of food items for human consumption,and nutraceuticals to deter deleterious free radical-induced life-threatening diseases. | Kajal Chakraborty Nammunayathuputhenkotta Krishnankartha Praveen Kodayan Kizekadath Vijayan Gonugontla Syda Rao | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，1： | 3 |

| 8 | Bioactivity guided isolation of mosquito larvicide from Piper longum显示文摘Objective:To isolate the larvicidal component from the fruits of Piper longum(P.longum) against the filariasis vector,Culex quinquefasciatus(C.quinquefasciatus).Methods:Pulverized fruits of P.longum were subjected to soxhlet extraction using series of organic solvents of increasing polarity.All the solvent extracts were verified for their larvicidal efficacy against 4th instar larvae of C.quinquefasciatus employing standard WHO procedure.Bioassayguided fractionation through column chromatography lead to the isolation of a bioactive amide, pipyahyine from the petroleum ether extract.Results:Petroleum ether extract was found to be the most active fraction among all the extracts tested with LC50 and LC90 being 1.03 and 2.04 ppm respectively.Whereas,pipyahyine,an isolated component of the same fraction was found to be even more effective than the parent extract in terms of LC50 being 0.58 and 1.88 ppm respectively. Conclusions:From the results,it is evident that P.longum can be considered as a powerful arsenal for the control of mosquito population. | Madhu.S Kumar Vijayan VA Shaukath AK | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，2： | 3 |
| 9 | Support vector regression modeling in recursive just-in-time learning framework for adaptive soft sensing of naphtha boiling point in crude distillation unit显示文摘Prediction of primary quality variables in real time with adaptation capability for varying process conditions is a critical task in process industries.This article focuses on the development of non-linear adaptive soft sensors for prediction of naphtha initial boiling point(IBP)and end boiling point(EBP)in crude distillation unit.In this work,adaptive inferential sensors with linear and non-linear local models are reported based on recursive just in time learning(JITL)approach.The different types of local models designed are locally weighted regression(LWR),multiple linear regression(MLR),partial least squares regression(PLS)and support vector regression(SVR).In addition to model development,the effect of relevant dataset size on model prediction accuracy and model computation time is also investigated.Results show that the JITL model based on support vector regression with iterative single data algorithm optimization(ISDA)local model(JITL-SVR:ISDA)yielded best prediction accuracy in reasonable computation time. | Venkata Vijayan S Hare Krishna Mohanta Ajaya Kumar Pani | 2021 | Petroleum Science2021，18，4： | 3 |
| 10 | Artificial Seed Production of Tylophora indica for Interim Storing and Swapping of Germplasm显示文摘Our research work demonstrates the single bead alginate-encapsulation, interim storing and conversion of Tylophora indica(Burm. Fil.) Merrill.Most effective encapsulation of in vitro nodal segments [(4 ± 1) mm long], ensuing in sphere-shaped artificial seeds of similar morphology, was achieved through 75 mmol·L^(-1)calcium chloride(CaCl_2 · 2H_2O) plus 3%(w/v) Na-alginate with 93.3% conversion frequency. The earliest conversion(within 7 days of incubation) of artificial seeds occurred in half-strength liquid Murashige and Skoog medium. Among the three different temperature regimes [(5 ± 1) °C,(15 ± 1) °C, and(25 ± 1) °C], storage of artificial seeds at(15 ± 1) °C executed the highest frequency of conversion(90%) after 15 days of storage. Lengthier storage significantly reduced the conversion frequency of artificial seeds irrespective of storage temperature. Nevertheless, the conversion frequency after 30 days of storage at(15 ± 1) °C was recorded at 70% without further decline even following45 days of storage, which evidently suggests that lower temperature(15 ± 1) °C is apt for storage and subsequent conversion of T. indica artificial seeds. The present protocol could be expedient for short-term storing and swapping of T. indica germplasms between national and international laboratories. | Saikat Gantait Joshitha Vijayan Adity Majee | 2017 | Horticultural Plant Journal2017，3，1： | 3 |

| 12 | Effect of angiotensin converting enzyme gene I/D polymorphism in South Indian children with nephrotic syndrome显示文摘Nephrotic syndrome is one of the most common childhood kidney diseases. It is mostly found in the age group of 2 to 8 years. Around 10%-15% of nephrotic syndrome cases are non-responders of steroid treatment(SRNS).Angiotensin converting enzyme(ACE)(I/D) gene association studies are important for detecting kidney disease and herein we assessed the association of ACE(I/D) polymorphism with nephrotic syndrome in South Indian children. We recruited 260 nephrotic syndrome(162 boys and 98 girls) and 218(140 boys and 78 girls) control subjects. ACE I/D polymorphism was analyzed by PCR using genotype allele specific primers. In ACE(I/D), we did not find significant association for the ungrouped data of nephrotic syndrome children and the control subjects. Kidney biopsies were done in 86 nephrotic syndrome cases(minimal change disease, n = 51;focal segmental glomerulosclerosis, n = 27;diffuse mesangial proliferation, n = 8). We segregated them into the minimal change disease/focal segmental glomerulosclerosis groups and observed that the ACE’D’ allele was identified with borderline significance in cases of focal segmental glomerulosclerosis and the ’Ⅰ’ allele was assessed as having very weak association in cases of minimal change disease. ’Ⅱ’ genotype was weakly associated with minimal change disease. Gender specific analysis revealed weak association of’ID’ genotype with female nephrotic syndrome in females. Dominant expression of DD genotype was observed in males with nephrotic syndrome. Our finding indicated that ACE(I/D) has moderate association with focal segmental glomerulosclerosis. However, due to the limited number of biopsy proven focal segmental glomerulosclerosis subjects enrolled, further studies are required to confirm these results. | Aravind Selvin Kumar Ramanathan Balakrishnan Karuppiah Murali Vijayan Kamaraj Raju Dhivakar Mani Rathika Chinniah Manikandan Thirunavukkarasu Padma Malini Ravi Jeyaram Illiayaraja Krishnan Prabha Senguttuvan | 2019 | The Journal of Biomedical Research2019，33，3： | 2 |
