1Preventive effects of geranylgeranylacetone on rat ethanolinduced gastritis显示文摘AIM:To establish a rat ethanol gastritis model,we evaluated the effects of ethanol on gastric mucosa and studied the preventive effects of geranylgeranylacetone on ethanol-induced chronic gastritis.METHODS:One hundred male Sprague-Dawley rats were randomly divided into 4 equal groups:normal control group,undergoing gastric perfusion of normal saline(NS) by gastrogavage;model control group and 2 model therapy groups that underwent gastric perfusion with ethanol(distillate spirits with 56% ethanol content) by gastrogavage for 4 wk.Low or high doses of geranylgeranylacetone were added 1 h before ethanol perfusion in the 2 model therapy groups,while the same amount of NS,instead of geranylgeranylacetone was used in that model control group.The rats were then sacrificed and stomachs were removed.The injury level of the gastric mucosa was observed by light and electron microscopy,and the levels of prostaglandin 2(PGE 2),endothelin-1(ET-1) and nitric oxide(NO) were measured by radioimmunoassay and the Griess method.RESULTS:The gastric mucosal epidermal damage score(EDS;4.5) and ulcer index(UI;12.0) of the model control group were significantly higher than that of the normal control group(0 and 0 respectively,all P = 0.000).The gastric mucosal EDS and UI of the 2 model therapy groups(EDS:2.5 and 2.0;UI:3.5 and 3.0) were significantly lower than that of the model control group(all P < 0.01).There was no statistically significant difference between the low-dose and high-dose model therapy groups.The expression value of plasma ET-1 of the model control group was higher than that of the normal control group(P < 0.01) and the 2 model therapy groups(all P < 0.01).The expression values of gastric mucosal PGE 2 and serum NO of the model control group were lower than those of the normal control group(all P < 0.05) and the 2 model therapy groups(all P < 0.05).The thickness of the gastric mucous layerand the hexosamine content in the model control group were significantly lower than that in the normal control group(all P < 0.01) and the 2 model therapy groups(all P < 0.05).Scanning and transmission electron microscopy observation showed that in the model control group,the epithelial junctions were vague,the intercellular joints disappeared and damage of the intracellular organelles were significantly worse than those in the normal control group.However,in the 2 model therapy groups,damage to the intercellular joints and organelles was ameliorate relative to the model control group.CONCLUSION:Administration of geranylgeranylacetone was correlated with a more favorable pattern of gastric mucosa damage after ethanol perfusion.The mechanism could be related to regulation of ET-1,NO and PGE 2.Jian-Wen Ning Guan-Bin Lin Feng Ji Jia Xu Najeeb Sharify 2012World Journal of Gastroenterology2012,18,18:12

5GNP6,a novel allele of MOC1,regulates panicle and tiller development in rice显示文摘The yield of rice is mostly affected by three factors,namely,panicle number,grain number and grain weight.Variation in panicle and grain numbers is mainly caused by tiller and panicle branches generated from axillary meristems(AMs).MOC1 encodes a putative GRAS family nuclear protein that regulates AM formation.Although several alleles of MOC1 have been identified,its variation in germplasm resources remains unclear.In the present study we characterized a novel mocl allele named gnp6 which has a thymine insertion in the coding sequence of the SAW motif in the GRAS domain.This mutation causes arrested branch formation.The SAW motif is necessary for nuclear localization of GNP6/MOC1 where it functions as a transcription factor or co-regulator.Haplotype analysis showed that the coding region of GNP6/MOC1 was conserved without any non-synonymous mutations in 240 rice accessions.However,variation in the promoter region might affect the expression of it and its downstream genes.Joint haplotype analysis of GNP6/MOC1 and MOC3 showed that haplotype combinations H9,H10 and H11,namely MOC1-Hap1 in combination with MOC3-Hap3,MOC3-Hap4 or MOC3-Hap5 could be bred to promote branch formation.These findings will enrich the genetic resources available for rice breeders.Zhanying Zhang Xingming Sun Xiaoqian Ma Bingxia Xu Yong Zhao Zhiqi Ma Gangling Li Najeeb Ullah Khan Yinghua Pan Yuntao Liang Hongliang Zhang Jinjie Li Zichao Li 2021The Crop Journal2021,9,1:6

7Black phosphorus-based field effect transistor devices for Ag ions detection显示文摘Black phosphorus(BP), an attractive two-dimensional(2 D) semiconductor, is widely used in the fields of optoelectronic devices, biomedicine, and chemical sensing. Silver ion(Ag^+), a commonly used additive in food industry, can sterilize and keep food fresh. But excessive intake of Ag^+will harm human health. Therefore, high sensitive, fast and simple Ag+detection method is significant. Here, a high-performance BP field effect transistor(FET) sensor is fabricated for Ag^+detection with high sensitivity, rapid detection speed, and wide detection concentration range. The detection limit for Ag^+is 10^(-10) mol/L. Testing time for each sample by this method is 60 s. Besides, the mechanism of BP-FET sensor for Ag^+detection is investigated systematically. The simple BP-FET sensor may inspire some relevant research and potential applications, such as providing an effective method for the actual detection of Ag^+, especially in witnessed inspections field of food.王慧德 David K Sang 郭志男 曹睿 赵劲来 Muhammad Najeeb Ullah Shah 范涛健 范滇元 张晗 2018Chinese Physics B2018,27,8:4
8Variations in OsSPL10 confer drought tolerance by directly regulating OsNAC2 expression and ROS production in rice显示文摘Drought is a major factor restricting the production of rice(Oryza sativa L.).The identification of natural variants for drought stress-related genes is an important step toward developing genetically improved rice varieties.Here,we characterized a member of the SQUAMOSA PROMOTER BINDING PROTEIN-LIKE(SPL)family,OsSPL10,as a transcription factor involved in the regulation of drought tolerance in rice.OsSPL10 appears to play a vital role in drought tolerance by controlling reactive oxygen species(ROS)production and stomatal movements.Haplotype and allele frequency analyses of OsSPL10 indicated that most upland rice and improved lowland rice varieties harbor the OsSPL10Hap1allele,whereas the OsSPL10Hap2allele was mainly present in lowland and landrace rice varieties.Importantly,we demonstrated that the varieties with the OsSPL10Hap1allele showed low expression levels of OsSPL10 and its downstream gene,OsNAC2,which decreases the expression of OsAP37 and increases the expression of OsCOX11,thus preventing ROS accumulation and programmed cell death(PCD).Furthermore,the knockdown or knockout of OsSPL10 induced fast stomatal closure and prevented water loss,thereby improving drought tolerance in rice.Based on these observations,we propose that OsSPL10 confers drought tolerance by regulating OsNAC2 expression and that OsSPL10Hap1could be a valuable haplotype for the genetic improvement of drought tolerance in rice.Yingxiu Li Shichen Han Xingming Sun Najeeb Ullah Khan Qun Zhong Zhanying Zhang Hongliang Zhang Feng Ming Zichao Li Jinjie Li 2023Journal of Integrative Plant Biology2023,65,4:2

17An Implementation of Haar Wavelet Based Method for Numerical Treatment of Time-fractional Schrdinger and Coupled Schrdinger Systems显示文摘The objective of this paper is to solve the timefractional Schr¨odinger and coupled Schr¨odinger differential equations(TFSE) with appropriate initial conditions by using the Haar wavelet approximation. For the most part, this endeavor is made to enlarge the pertinence of the Haar wavelet method to solve a coupled system of time-fractional partial differential equations. As a general rule, piecewise constant approximation of a function at different resolutions is presentational characteristic of Haar wavelet method through which it converts the differential equation into the Sylvester equation that can be further simplified easily. Study of the TFSE is theoretical and experimental research and it also helps in the development of automation science,physics, and engineering as well. Illustratively, several test problems are discussed to draw an effective conclusion, supported by the graphical and tabulated results of included examples, to reveal the proficiency and adaptability of the method.Najeeb Alam Khan Tooba Hameed 2019IEEE/CAA Journal of Automatica Sinica2019,6,1:1
18RBF Based Localized Method for Solving Nonlinear Partial Integro-Differential Equations显示文摘In this work,a numerical scheme is constructed for solving nonlinear parabolictype partial-integro differential equations.The proposed numerical scheme is based on radial basis functions which are local in nature like finite difference numerical schemes.The radial basis functions are used to approximate the derivatives involved and the integral is approximated by equal width integration rule.The resultant differentiation matrices are sparse in nature.After spatial approximation using RBF the partial integro-differential equations reduce to the system of ODEs.Then ODEs system can be solved by various types of ODE solvers.The proposed numerical scheme is tested and compared with other methods available in literature for different test problems.The stability and convergence of the present numerical scheme are discussed.Marjan Uddin Najeeb Ullah Syed Inayat Ali Shah 2020Computer Modeling in Engineering & Sciences2020,,6:1
