| 1 | Risk factors for colonoscopic perforation: A population-based study of 80118 cases显示文摘AIM: To assess the incidence and risk factors associated with colonic perforation due to colonoscopy. METHODS: This was a retrospective cross-sectional study. Patients were retrospectively eligible for inclusion if they were 18 years and older and had an inpatient or outpatient colonoscopy procedure code in any facility within the Geisinger Health System during the period from January 1, 2002 to August 25, 2010. Data are presented as median and inter-quartile range, for continuous variables, and as frequency and percentage for categorical variables. Baseline comparisons across those with and without a perforation were made using the two-sample t -test and Pearson's χ2 test, as appropriate.RESULTS: A total of 50 perforations were diagnosed out of 80118 colonoscopies, which corresponded to an incidence of 0.06% (95%CI: 0.05-0.08) or a rate of 6.2 per 10000 colonoscopies. All possible risk factors associated with colonic perforation with a P -value < 0.1 were checked for inclusion in a multivariable logbinomial regression model predicting 7-d colonic perforation. The final model resulted in the following risk factors which were significantly associated with risk of colonic perforation: age, gender, body mass index, albumin level, intensive care unit (ICU) patients, inpatient setting, and abdominal pain and Crohn's disease as indications for colonoscopy. CONCLUSION: The cumulative 7 d incidence of colonic perforation in this cohort was 0.06%. Advanced age and female gender were significantly more likely to have perforation. Increasing albumin and BMI resulted in decreased risk of colonic perforation. Having a colonoscopy indication of abdominal pain or Crohn's disease resulted in a higher risk of colonic perforation. Colonoscopies performed in inpatients and particularly the ICU setting had substantially greater odds of perforation. Biopsy and polypectomy did not increase the risk of perforation and only three perforations occurred with screening colonoscopy. | Uzair Hamdani Raza Naeem Fyeza Haider Pardeep Bansal Michael Komar David L Diehl H Lester Kirchner | 2013 | World Journal of Gastroenterology2013，19，23： | 9 |
| 2 | Longest duration of retention of video capsule: A case report and literature review显示文摘Video capsule endoscopy (VCE) is a safe innovative tool for investigating obscure gastrointestinal bleeding, Crohn's disease and other small bowel pathologies. The capsule is usually excreted with faeces within 24-48 h. Retention of capsule rarely occurs, and it usually depends on the indication of VCE. The longest reported case of capsule retention in the literature is 2.5 years. Surgical approach is considered effective to retrieve the retained capsule. We present a case of asymptomatic retention of capsule for four and half years in a 49-year-old man who underwent VCE to explore the cause of obscure gastrointestinal bleeding. It was successfully retrieved endoscopically. We will also briefly review the literature regarding the causes, different presentations and management of capsule retention. | Mukul Bhattarai Pardeep Bansal Yakub Khan | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，7： | 7 |

| 4 | Soil Carbon Dynamics Under Changing Climate A Research Transition from Absolute to Relative Roles of Inorganic Nitrogen Pools and Associated Microbial Processes:A Review显示文摘It is globally accepted that soil carbon(C) dynamics are at the core of interlinked environmental problems, deteriorating soil quality and changing climate. Its management remains a complex enigma for the scientific community due to its intricate relationship with soil nitrogen(N) availability and moisture-temperature interactions. This article reviews the management aspects of soil C dynamics in light of recent advances, particularly in relation to the availability of inorganic N pools and associated microbial processes under changing climate. Globally, drastic alterations in soil C dynamics under changing land use and management practices have been primarily attributed to the variation in soil N availability, resulting in a higher decomposition rate and a considerable decline in soil organic C(SOC) levels due to increased soil CO_2 emissions, degraded soil quality, and increased atmospheric CO_2 concentrations,leading to climate warming. Predicted climate warming is proposed to enhance SOC decomposition, which may further increase soil N availability, leading to higher soil CO_2 efflux. However, a literature survey revealed that soil may also act as a potential C sink, if we could manage soil inorganic N pools and link microbial processes properly. Studies also indicated that the relative, rather than the absolute, availability of inorganic N pools might be of key importance under changing climate, as these N pools are variably affected by moisture-temperature interactions, and they have variable impacts on SOC turnover. Therefore, multi-factorial studies are required to understand how the relative availability of inorganic N pools and associated microbial processes may determine SOC dynamics for improved soil C management. | pratap srivastava rishikesh singh sachchidanand tripathi pardeep singh shikha singh hema singh akhilesh singh raghubanshi pradeep kumar mishra | 2017 | Pedosphere2017，27，5： | 5 |
| 5 | Impact of sole and combined application of biochar,organic and chemical fertilizers on wheat crop yield and water productivity in a dry tropical agro-ecosystem显示文摘Agriculture under changing climate scenario is facing major challenges of water scarcity and resource imbalances.Crop water productivity(WP)may act as an indicator of crop responses to water limitation.Organic amendments such as biochar and manure application to soil are suggested for improving soil quality and reducing water requirements from agricultural sector.However,studies exploring the impact of biochar as sole or in combination with organic and/or chemical fertilizers on WP in dry tropical agro-ecosystems are limited.In this study,we observed the effect of rice-husk ash(RHA,biochar)along with farm-yard manure(FYM)and chemical fertilizers(CF)under varying water conditions on soil hydro-physical properties,yield and WP of wheat crop.Water-filled pore space(WFPS),grain and straw yield,irrigation and total water productivity varied significantly(at P<0.001)at treatment level.Grain and straw yield were found higher under sole and combined CF applied treatments.Sole and combined RHA and FYM amendment improved water holding capacity(WHC)and WFPS,whereas a decrease in crop yield was observed as compared to the control.Irrigation and total water productivity were found higher under combined RHA+FYM and sole CF treatments with reduced water supply(except sole CF)as compared to control and sole RHA treatments with full water irrigation.Crop water productivity was found positively correlated with grain and straw yields,however,significant correlations were not observed with WHC and WFPS.Results indicate that increasing soil hydro-physical properties in silty-loam soil may hinder crop yield and WP under sole biochar applied soils.Overall,the implications of the study would help in devising agro-management practices based on combined application of RHA and FYM with reduced chemical fertilizer and water inputs to mitigate the impacts of climate change without compromising crop yield in the highly vulnerable dry tropical agro-ecosystem of India.Moreover,long-term studies are needed in these ecosystems to identify the appropriate agricultural package for mitigating the forthcoming water scarcity conditions. | Rishikesh Singh Pardeep Singh Hema Singh A.S.Raghubanshi | 2019 | Biochar2019，1，2： | 5 |
| 6 | Surface defect engineering of metal oxides photocatalyst for energy application and water treatment显示文摘Despite metal oxides offer excellent characteristics in the field of photocatalysis,they often suffer from charge carrier recombination as well as limited visible response,which indeed reduce the charge kinetics process and ultimately reduce the photocatalytic output.Defect engineering is a sophisticated technique to manufacture defects and alter the geometric structure and chemical environment of the host.The present study provides an all-inclusive outline of recent developments on the classification of metal oxide defects based on the dimensions of a host crystal lattice.Precisely,surface modification of metal oxides through 0D(point),1D(line),2D(planar),and 3D(volume)defects with their subsequent mechanism and impact on photocatalytic performance are presented.By wisely amending the morphology(cores along with the shells)and electronic structure of metal oxide photocatalysts(TiO_(2),ZnO,Bi_(2)O_(3),Fe_(2)O_(4) etc.)through different attuned and veritable approaches,their photocatalytic activity can be substantially improved.Optimal studies on defect engineering not only expose the altered physicochemical features but also modulate the electron-hole pair dynamics,stability,and active radical production for various photoredox reactions.Altered atomic,as well as electronic configuration,facilitated a photocatalyst material to have different optical features,adsorption properties along with improved carrier transfer as well as isolation rate.Thus,the systematic exploration of photocatalytic rudiments of defect rich metal oxide for various applications such as H_(2) evolution,CO_(2) reduction,pollutant degradation,and bacterial disinfection could bring significant research advancement in this field. | Pankaj Raizada Vatika Soni Abhinandan Kumar Pardeep Singh Aftab Aslam Parwaz Khan Abdullah M.Asiri Vijay Kumar Thakur Van-Huy Nguyen | 2021 | Journal of Materiomics2021，7，2： | 4 |
| 7 | An experimental study for optimization of high range water reducing superplasticizer in self compacting concrete显示文摘Concrete is extensively used construction material in the infrastructure development industry.With increase in technical knowhow,the need of research for high performance concretes such as self-compacting concrete(SCC)has increased in the last decade.The adaptability of SCC is due to its fluidic behavior in fresh state.However,to develop SCC using indigenous materials,the lack of standardized mix design procedures is the biggest impediment.Although with the advent of chemical admixtures,it is possible to achieve concrete with high fluidity,but at the same time durability issues require more attention.To have these fresh state properties SCC mixes are typically designed with high powder contents,and chemical admixtures.Proportioning and optimization of these materials is a key issue in the mix design of SCC.This paper focuses mainly on experimental study to optimize dosages of superplasticizer for mortar of SCC and then in concrete mixture itself. | Rahul DUBEY Pardeep KUMAR | 2013 | Frontiers of Structural and Civil Engineering2013，7，1： | 3 |
| 8 | 2020 Roadmap on two-dimensional nanomaterials for environmental catalysis显示文摘Environmental catalysis has drawn a great deal ofattention due to its clean ways to produce useful chemicals or carry out some chemical processes.Photocatalysis and electrocatalysis play important roles in these fields.They can decompose and remove organic pollutants from the aqueous environment,and prepare some fine chemicals.Moreover,they also can carry out some important reactions,such as 02 reduction reaction(ORR),O2 evolution reaction(OER),H2 evolution reaction(HER),CO2 reduction reaction(C02 RR),and N2 fixation(NRR).For catalytic reactions,it is the key to develop high-performance catalysts to meet the demand fortargeted reactions.In recentyears,two-dimensional(2 D) materials have attracted great interest in environmental catalysis due to their unique layered structures,which offer us to make use of their electronic and structural characteristics.Great progress has been made so far,including graphene,black phosphorus,oxides,layered double hydroxides(LDHs),chalcogenides,bismuth-based layered compounds,MXenes,metal organic frameworks(MOFs),covalent organic frameworks(COFs),and others.This content drives us to invite many famous groups in these fields to write the roadmap on two-dimensional nanomaterials for environmental catalysis.We hope that this roadmap can give the useful guidance to researchers in future researches,and provide the research directions. | Yulu Yang Mingguang Wu Xingwang Zhu Hui Xu Si Ma Yongfeng Zhi Hong Xia Xiaoming Liu Jun Pan Jie-Yinn Tang Siang-Piao Chai Leonardo Palmisano Francesco Parrino Junli Liu Jianzhong Ma Ze-Lin Wang Ling Tan Yu-Fei Zhao Yu-Fei Song Pardeep Singh Pankaj Raizada Deli Jiang Di Li R.A.Geioushy Jizhen Ma Jintao Zhang Song Hu Rongjuan Feng Gang Liu Minghua Liu Zhenhua Li Mingfei Shao Neng Li Jiahe Peng Wee-Jun Ong Nikolay Kornienko Zhenyu Xing Xiujun Fan Jianmin Ma | 2019 | Chinese Chemical Letters2019，30，12： | 2 |
