| 2 | Inhibition of pacemaker activity in interstitial cells of Cajal by LPS via NF-κB and MAP kinase显示文摘AIM:To investigate lipopolysaccharide(LPS) related signal transduction in interstitial cells of Cajal(ICCs) from mouse small intestine.METHODS:For this study,primary culture of ICCs was prepared from the small intestine of the mouse.LPS was treated to the cells prior to measurement of the membrane currents by using whole-cell patch clamp technique.Immunocytochemistry was used to examine the expression of the proteins in ICCs.RESULTS:LPS suppressed the pacemaker currents of ICCs and this could be blocked by AH6809,a prostaglandin E2-EP2 receptor antagonist or NG-Nitro-Larginine Methyl Ester,an inhibitor of nitric oxide(NO) synthase.Toll-like receptor 4,inducible NO synthase or cyclooxygenase-2 immunoreactivity by specific antibodies was detected on ICCs.Catalase(antioxidant agent) had no action on LPS-induced action in ICCs.LPS actions were blocked by nuclear factor kB(NF-kB) inhibitor,actinomycin D(a gene transcription inhibitor),PD 98059(a p42/44 mitogen-activated protein kinases inhibitor) or SB 203580 [a p38 mitogen-activated protein kinases(MAPK) inhibitor].SB 203580 also blocked the prostaglandin E2-induced action on pacemaker currents in ICCs but not NO.CONCLUSION:LPS inhibit the pacemaker currents in ICCs via prostaglandin E2-and NO-dependent mechanism through toll-like receptor 4 and suggest that MAPK and NF-kB are implicated in these actions. | Dong Chuan Zuo Seok Choi Pawan Kumar Shahi Man Yoo Kim Chan Guk Park Young Dae Kim Jun Lee In Yeoup Chang Insuk So Jae Yeoul Jun | 2013 | World Journal of Gastroenterology2013,19,8: | 9 |
| 3 | Implications of Climate Change on Streamflow of a Snow-Fed River System of the Northwest Himalaya显示文摘Air temperature and snow cover variability are sensitive indicators of climate change. This study was undertaken to forecast and quantify the potential streamflow response to climate change in the Jhelum River basin. The implications of air temperature trends (+0.11°C/decade) reported for the entire north-west Himalaya for past century and the regional warming (+0.7°C/decade) trends of three observatories analyzed between last two decades were used for future projection of snow cover depletion and stream flow. The streamflow was simulated and validated for the year 2007-2008 using snowmelt runoff model (SRM) based on in-situ temperature and precipitation with remotely sensed snow cover area. The simulation was repeated using higher values of temperature and modified snow cover depletion curves according to the assumed future climate. Early snow cover depletion was observed in the basin in response to warmer climate. The results show that with the increase in air temperature, streamflow pattern of Jhelum will be severely affected. Significant redistribution of streamflow was observed in both the scenarios. Higher discharge was observed during spring-summer months due to early snowmelt contribution with water deficit during monsoon months. Discharge increased by 5% 40% during the months of March to May in 2030 and 2050. The magnitude of impact of air temperature is higher in the scenario-2 based on regional warming. The inferences pertaining to change in future streamflow pattern can facilitate long term decisions and planning concerning hydro-power potential, waterresource management and flood hazard mapping in the region. | Vaibhav SHARMA Varunendra Dutta MISHRA Pawan Kumar JOSHI | 2013 | Journal of Mountain Science2013,10,4: | 7 |
| 4 | A high-resolution optically addressed spatial light modulator based on ZnO nanoparticles显示文摘An optically addressed spatial light modulator(OASLM)can modulate the wavefront of a read light by displaying a phase pattern or a hologram configured by the intensity distribution of a write light.Using ZnO nanoparticles(NPs)as a novel photoconductor,a high-resolution OASLM was fabricated.A ZnO NP suspension was spin-coated on an indium tin oxide(ITO)-coated glass substrate and annealed to form a photosensitive layer.The device was characterized electrically and optically.The device was operated at low driving voltages in the transmission mode.Updatable recording of a diffraction grating up to 825 lp mm^(-1) with a diffraction efficiency(DE)of 0.05%and binary holograms with pixel sizes from 2 mm down to 0.72 mm were demonstrated using a 405 nm wavelength write laser and a 635 nm wavelength read laser. | Pawan Kumar Shrestha Young Tea Chun Daping Chu | 2015 | Light(Science & Applications)2015,4,1: | 5 |
| 5 | Role of angiotensin converting enzyme and angiotensinogen gene polymorphisms in angiotensin converting enzyme inhibitor-mediated antiproteinuric action in type 2 diabetic nephropathy patients显示文摘AIM To investigate the role of genetic variants of angiotensin converting enzyme(ACE) and angiotensinogen(AGT) genes in the antiproteinuric efficacy of ACE inhibitor therapy in diabetic nephropathy(DN) patients.METHODS In the present study, 270 type 2 diabetes mellitus patients with nephropathy were enrolled and treated with ACE inhibitor(ramipril) and followed at 6 mo for renal function and albumin excretion by estimating serum creatinine, end stage renal disease, and albumin/creatinine ratio(ACR) in urine. Genotyping of ACE I/D and AGT M235 T polymorphisms were performed by using primer specific polymerase chain reaction(PCR) and PCR-RFLP techniques, respectively. RESULTS Forty-eight percent of DN patients(responders) benefited with respect to proteinuria from ACE inhibitor therapy at 6 mo follow-up. A significant reduction in ACR was observed after 6 mo treatment with ACE inhibitor irrespective of whether DN patients were micro-albuminuric(≥ 30 and < 300 mg/g creatinine) or macro-albuminuric(≥ 300 mg/g creatinine) at the time of enrollment. However, macro-albuminuric patients(55%) showed better response to therapy. A reduction in urinary ACR was found independent of genotypes of ACE I/D and AGT M235 T polymorphisms although macro-albuminuric patients having TT genotype showed statistically insignificant increased response(72%). CONCLUSION ACE inhibitor therapy reduced urinary ACR by ≥ 30% in 50% of DN patients and the response is independent of ACE I/D and AGT M235 T polymorphisms. | Neerja Aggarwal Pawan Kumar Kare Parul Varshney Om Prakash Kalra Sri Venkata Madhu Basu Dev Banerjee Anil Yadav Alpana Raizada Ashok Kumar Tripathi | 2017 | World Journal of Diabetes2017,8,3: | 4 |
| 6 | Hybridization between salt resistant and salt susceptible genotypes of mungbean(Vigna radiata L.Wilczek)and purity testing of the hybrids using SSRs markers显示文摘Six cultivated and two wild genotypes of mungbean(Vigna radiata L. Wilczek) possessing variation for phenotypic and genotypic response for salt tolerance were hybridized. Hybridization results showed successful pod set and significant variations in cross-compatibility of investigated genotypes. Genotypes PLM 380 and PLM 562 showed promising combining ability with all genotypes. Results revealed significant crossing compatibility between V. radiata and V. sublobata. The cross ability ranged from 1.99 to 5.12%(average 3.08%). Molecular analysis confirmed the hybrids purity. All F_1 seeds were bold, green/shiny green and germinated between 3 to 5 days. Hybrid plants were normal, fertile and healthier over their respective progenitors. Uniform flowering and maturity of the hybrids showed absence of any defect or alteration in plant habit and life cycle of the hybrids. The hybrid plants showed increase in yield characteristics as no. of pods, pod length, 100 seeds weight, and yield per plant. Number of pods containing F_2 seeds ranged from 5–8 per cluster. The F_2 seeds were collected and stored for further research. Present study suggests that salt resistant wild relatives or cultivars of mungbean can be explored by breeding as a source of useful traits/genes providing salt tolerance. This may help in development of best mungbean variety for saline prone areas. Micro-satellite markers linked to the trait/genes may assist breeding by early selection of the genotypes compared to the phenotypic screening. | Sehrawat Nirmala Yadav Mukesh Bhat Kangila Venkataraman Sairam Raj Kumar Jaiwal Pawan Kumar | 2016 | Journal of Integrative Agriculture2016,15,3: | 3 |
| 7 | Value of multi-disciplinary input into laparoscopic management of rectal cancer-An observational study显示文摘AIM To assess the impact of multi-disciplinary teams(MDTs)management in optimising the outcome for rectal cancers.METHODS We undertook a retrospective review of a prospectively maintained database of patients with rectal cancers(defined as tumours≤15 cm from anal verge)discussed at our MDT between Jan 2008 and Jan 2011.The data was validated against the national database to ensure completeness of dataset.The clinical course and follow-up data was validated using the institution’s electronic patient records.The data was analysed in terms of frequencies and percentages.Significance of any differences were analysed usingχ2 test.A Kaplan-Meier analysis was performed for overall survival and disease free survival.RESULTS Following appropriate staging,one hundred and thirtythree patients were suitable for potentially curative resections.Seventy two(54%)were upper rectal cancer(URC)-tumour was>6 cm from the anal verge and 61(46%)were lower rectal cancers(LRC)-lower extent of the tumour was palpable≤6 cm.Circumferential resection margin(CRM)appeared threatened on preoperative MRI in 19/61(31%)patients with LRC requiring neo-adjuvant therapy(NAT).Of the 133 resections,118(89%)were attempted laparoscopically(5%conversion rate).CRM was positive in 9(6.7%)patients;Median lymph node harvest was 12(2-37).Major complications occurred in 8(6%)patients.Median follow-up was 53 mo(0-82).The 90-d mortality was 2(1.5%).Over the followup period,disease related mortality was 11(8.2%)and overall mortality was 39(29.3%).Four(3%)patients had local recurrence and 22(16.5%)patients had distant metastases.CONCLUSION Management of rectal cancers can be optimized with multidisciplinary input to attain acceptable long-term oncological outcomes even when incorporating a laparoscopic approach to rectal cancer resection. | Pawan Kumar Dhruva Rao Sooriyaratchige Pradeep Manjula Peiris Seema Safia Arif Rhodri A Davies Ashraf Gergies Masoud Puthucode Narayanan Haray | 2017 | World Journal of Gastrointestinal Surgery2017,9,6: | 2 |
| 8 | Multi-temporal forest cover dynamics in Kashmir Himalayan region for assessing deforestation and forest degradation in the context of REDD+ policy显示文摘The role of forests is being actively considered under the agenda of REDD+(Reducing Emissions from Deforestation and Forest Degradation plus) aimed at reducing emissions related to changes in forest cover and forest quality. Forests in general have undergone negative changes in the past in the form of deforestation and degradation, while in some countries positive changes are reported in the form of conservation, sustainable management of forests and enhancement of carbon stock. The present study in the Kashmir Himalayan forests is an effort to assess historical forest cover changes that took place from 1980 to 2009 and to predict the same for 2030 on the basis of past trend using geospatial modeling approach. Landsat data(Multispectral Scanner(MSS),Thematic Mapper(TM) and Enhanced Thematic Mapper(ETM+)) was used for the years 1980, 1990 and(2001, 2009) respectively and change detection analysis between the dates was performed. The maps generated were validated through ground truthing. The study area(3375.62 km^2) from 1980-2009 has uffered deforestation and forest degradation of about 126 km^2 and 139.02 km^2 respectively which can be claimed under negative options of REDD+, while as the area that experienced no change(1514 km^2) can be claimed under conservation. A small area(23.31 km^2) observed as positive change can be claimed under positive options. The projected estimates of forest cover for 2030 showed increased deforestation and forest degradation on the basis of trend analysis using Cellular Automata(CA) Markov modeling. Despite the fact that country as a whole has registered a net positive change in the past few decades, but there are regions like Kashmir region of western Himalaya which have constantly undergoing deforestation as well as degradation in the past few decades. | Akhlaq Amin WANI Pawan Kumar JOSHI Ombir SINGH Sumera SHAFI | 2016 | Journal of Mountain Science2016,13,8: | 2 |
| 9 | Understanding Brown Planthopper Resistance in Rice: Genetics, Biochemical and Molecular Breeding Approaches显示文摘Brown planthopper(BPH,Nilaparvata lugens St自I)is the most devastating pest of rice in Asia and causes significant yield loss annually.Around 37 BPH resistance genes have been identified so far in indica,African rice varieties along with wild germplasms such as Oryza officinalis,O.minuta,O.nivara,O.punctata,O.rufipogon and O,latifolia.Genes/QTLs involved in BPH resistance,including Bph1,bph2/BPH26,Bph3,Bph6,bph7,BPH9,Bph12,Bph14,Bph15,Bph17,BPH18,bph19,Bph20,Bph21(t),Bph27,Bph27©Bph28(t),BPH29,QBph3,QBph4,QBph4.2,Bph30,Bph32,Bph33,Bph35 and Bph36,have been fine-mapped by different researchers across the globe.The majority of genes/QTLs are located on rice chromosomes 1,3,4,6,11 and 12.Rice plants respond to BPH attack by releasing various endogenous metabolites like proteinase inhibitors,callose,secondary metabolites(terpenes,alkaloids,flavonoid,etc.)and volatile compounds.Besides that,hormonal signal pathways mediating(antagonistic/synergistic)resista nee responses in rice have been well studied.Marker-assisted breedi ng and genome editi ng techniq ues can also be adopted for improving resista nee to novel BPH biotypes. | Lakesh MUDULI Sukanta Kumar PRADHAN Abinash MISHRA Debendra Nath BASTIA Kailash Chandra SAMAL Pawan Kumar AGRAWAL Manasi DASH | 2021 | Rice science2021,28,6: | 2 |

| 13 | An indicator-based approach to assess village-level social and biophysical vulnerability of agriculture communities in Uttarakhand,India显示文摘With the growing recognition to myriad forms of current and future threats in the mountain agriculture systems,there is a pressing need to holistically understand the vulnerability of mountain agriculture communities.The study aims to assess the biophysical and social vulnerability of agriculture communities using an indicator-based approach for the state of Uttarakhand,India.A total of 14 indicators were used to capture biophysical vulnerability and 22 for social vulnerability profiles of15285 villages.Vulnerability analysis was done at village level with weights assigned to each indicator using Analytical Hierarchical Process(AHP).The results of the study highlight the presence of very high biophysical vulnerability(0.82 ± 0.10) and high social vulnerability(0.65 ± 0.15) within the state.Based on the results,it was found that incidences of high biophysical vulnerability coincide with presence of intensified agriculture land and absence of dense forest.Higher social vulnerability scores were found in villages with an absence of local institutions(like Self Helping Groups(SHGs)),negligible infrastructure facilities and higher occupational dependence on agriculture.A contrast was observed in the vulnerability scores of villages present in the three different altitudinal zones in the study area,indicating respective vulnerability generating conditions existing in these three zones.Biophysical vulnerability was recorded to be highest in the villages falling in the lower zone and lowest in the upper zone villages;whereas,social vulnerability was found to be highest in the middle zone villages and lowest in lower zone villages.Our study aids policy makers in identifying areas for intervention to expedite agriculture adaptation planning in the state.Additionally,the adaptation programmes in the region need to be more context-specific to accommodate the differential altitudinal vulnerability profiles. | Roopam SHUKLA Kamna SACHDEVA Pawan Kumar JOSHI | 2016 | Journal of Mountain Science2016,13,12: | 2 |
