1Selenium Accumulation and Antioxidant Status of Rice Plants Grown on Seleniferous Soil from Northwestern India显示文摘Greenhouse experiment was conducted to investigate selenium accumulation and its antioxidant response in two rice varieties(PR116 and Pusa Basmati 1121) grown on normal and seleniferous soils. The plant growth was reduced at early developmental stages and flowering was delayed by a period of 10 d on seleniferous soil. Selenium accumulation increased by 3–20 and 13–14 folds in leaves, 18 and 3 folds in grains from Pusa Basmati 1121 and PR116 varieties, respectively. Selenium accumulation in leaves from rice plants grown on seleniferous soil resulted in significant increase in chlorophyll content, hydrogen peroxide, proline, free amino acids, total phenol and tannin contents. Lipid peroxidation levels and peroxidase activities in leaves increased whereas catalase activity showed a reverse trend. It is concluded that selenium accumulation decreased dry matter content in rice during crop development but these plants were able to combat selenium toxicity by inducing alterations in their defense system.Sucheta SHARMA Reeti GOYAL Upkar Singh SADANA 2014Rice science2014,21,6:3
2Selenium Alleviates Carbohydrate Metabolism and Nutrient Composition in Arsenic Stressed Rice Plants显示文摘This study reported the influence of selenium(Se)on carbohydrate composition and some related enzymes and nutrient compositions of arsenic(As)stressed rice plants.Rice plants of cultivar PR126 were grown on soil amended with As in a range of 25-100μmol/kg with and without 0.5 or 1.0 mg/kg Se.Total soluble sugars(TSS)and reducing sugars(RS)increased in leaves of As stressed plants at the tillering and grain filling stages whereas sucrose and starch contents showed the reverse trend.Se supplementation to As stressed plants further increased TSS and RS,and enhanced sucrose phosphate synthase activity in rice leaves,thus improving sucrose content and the tolerance to As stress of the plants.Se alone or in combination with As resulted in lower As accumulation in rice husk and grains,and the highest reduction was observed in Se applied at 1.0 mg/kg compared to the corresponding As treatments alone.As may limit the accumulations of Na,Mg,K,Ca,Fe,Zn and Mn in rice grains,which are essential for humans.Binary application of different combinations of As and Se protected the plants against As and increased the mineral content in rice grains.Addition of Se in As treated soil significantly alleviated As stress by enhancing grain yields compared to the corresponding As treatment.It is concluded that Se induced amelioration of the toxic impact of As in rice either by modulating carbohydrate composition and/or nutrient uptake is one of the mechanisms to alleviate As stress in plants.Sheetal BHADWAL Sucheta SHARMA 2022Rice science2022,29,4:2

4Prevalence of internet addiction among college students in the Indian setting:a systematic review and meta-analysis显示文摘Background The internet is an integral part of everyone’s life.College going adolescents are highly vulnerable to the misuse of the internet.Aims To estimate the pooled prevalence of internet addiction(IA)among college students in India.Methods Literature databases(PubMed,Web of Science,Scopus,EMBASE,PsycINFO and Google Scholar)were searched for studies assessing IA using the Young Internet Addiction Test(Y-IAT)among adolescents from India,published in the English language up to December 2020.We included studies from 2010 to 2020 as this is the marked era of momentum in wireless internet connectivity in India.The methodological quality of each study was scored,and data were extracted from the published reports.Pooled prevalence was estimated using the fixed-effects model.Publication bias was evaluated using Egger’s test and visual inspection of the symmetry in funnel plots.Results Fifty studies conducted in 19 states of India estimated the prevalence of IA and the overall prevalence of IA as 19.9%(95%CI:19.3%to 20.5%)and 40.7%(95%CI:38.7%to 42.8%)based on the Y-IAT cut-off scores of 50 and 40,respectively.The estimated prevalence of severe IA was significantly higher in the Y-IAT cut-off points of 70 than 80(12.7%(95%CI:11.2%to 14.3%)vs 4.6%(95%CI:4.1%to 5.2%)).The sampling method and quality of included studies had a significant effect on the estimation of prevalence in which studies using non-probability sampling and low risk of bias(total quality score≥7)reported lower prevalence.The overall quality of evidence was rated as‘moderate’based on the Grading of Recommendations Assessment,Development and Evaluation criteria.Conclusions Our nationally representative data suggest that about 20%to 40%of college students in India are at risk for IA.There is a need for further research in the reconsideration of Y-IAT cut-off points among Indian college students.Jaison Joseph Abin Varghese Vijay VR Manju Dhandapani Sandeep Grover Suresh Sharma Deepika Khakha Sucheta Mann Biji P Varkey 2021General Psychiatry2021,34,4:1
