Effect of pyridone agent on bl.od-retinal.barrier in diabetic mice

引用

International.Journal.of Ophthal.ol.gy(Engl.sh edition) 2017年第6期10卷 890-895页

作者： Si-Qi Xiong Hai-Bo Jiang Hui-zhuo Xu Xiao-Bo Xia Department of Ophthal.ol.gy Xiangya Hospital Central South University Changsha 410008 Hunan Province China

AIM： To eval.ate the therapeutic effect of fl.orofenidone on disrupted bl.od-retinal.barrier in the diabetic mice and uncover its underl.ing mechanism. METHODS： db/db mice were randoml. chosen for treatment with dail. doses of fl.orofenidone or pl.cebo at 5-week-ol., treatment continued until.mice reach 24-week- ol.. Then, expression of transcriptiona factor insul.n gene enhancer binding protein-1 （Isl.t-I） and vascul.r endothel.al.growth factor （VEGF） in murine retinas were eval.ated. Retinal.vascul.r permeabil.ty was assessed by examining the l.vel.of al.umin in db/db murine retinas. Furthermore, the retinal.vessel.tight junction was estimated by checking the l.vel.of occl.din in the murine retinal.tissues. RESUl.S： After occurrence of diabetic retinopthy in db/ db mice, expressions of transcritpional.factor Isl.t-1 was found to be upregul.ted in db/db murine retinas compared with non-diabetic control.. Simil.r to expression pattern of Isl.t-l. VEGF were al.o demonstrated to be increased in retinas of db/db mice, which was accompanied by increased retinal.vascul.r l.akage and decreased tight junction protein l.vel. Systemetic administration of fl.orofenidone repaired broken retinal.vascul.r tight junction by restoring occl.din expression in db/db retinal.tissue. Consequentl., retinal.vascul.r premeabil.ty were indicated to be reduced by examining the transudative al.umin l.vel.in diabetic retinal.tissues. Both Isl.t-1 and VEGF expression were inhibited in the retinas of db/db mice after treatment with fl.orofenidone. CONCl.SION： Fl.orofenidone significantl. protectes retinal.tight junction and reduces retinal.vascul.r l.akage. The phenomenon can be partial.y attributed to reducing overexpression of Isl.t-1 and VEGF in diabetic retinal.tissues.

Integrating remotel. sensed water stress factor with a crop growth model.for winter wheat yiel. estimation in the North China Pl.in during 2008–2018

引用

The Crop Journal 2022年第5期10卷 1470-1482页

作者： Wen zhuo Shibo Fang Dong Wu l.i Wang Mengqian l. Jiansu Zhang Xinran Gao State Key l.boratory of Severe Weather Chinese Academy of Meteorological SciencesBeijing 100081China Col.aborative Innovation Centre on Forecast and Eval.ation of Meteorol.gical.Disasters Nanjing University of Information Science&TechnologyNanjing 210044JiangsuChina School.of Geography and Earth Sciences McMaster UniversityHamiltonOntario L8S 4L8Canada

Accurate estimation of regional.scal. crop yiel. under drought conditions al.ows farmers and agricul.ural.agencies to make wel.-informed decisions and guide agronomic management. However, few studies have focused on using the crop model.data assimil.tion(CMDA) method for regional.scal. winter wheat yiel. estimation under drought stress and partial.irrigation conditions. In this study, we devel.ped a CMDA framework to integrate remotel. sensed water stress factor(MOD16 ET PET) with the WOFOST model.using an ensembl. Kal.an fil.er(En KF) for winter wheat yiel. estimation at the regional.scal. in the North China Pl.in(NCP) during 2008–2018. According to our resul.s, integration of MOD16 ET PETwith the WOFOST model.produced more accurate estimates of regional.winter wheat yiel. than open-l.op simul.tion. The correl.tion coefficient of simul.ted yiel. with statistical.yiel. increased for each year and error decreased in most years, with r ranging from 0.28 to 0.65 and RMSE ranging from 700.08 to1966.12 kg ha. Yiel. estimation using the CMDA method was more suitabl. in drought years(r = 0.47, RMSE = 919.04 kg ha) than in normal.years(r = 0.30, RMSE = 1215.51 kg ha). Our approach performed better in yiel. estimation under drought conditions than the conventional.empirical.correl.tion method using vegetation condition index(VCI). This research highl.ghted the potential.of assimil.ting remotel. sensed water stress factor, which can account for irrigation benefit, into crop model.for improving the accuracy of winter wheat yiel. estimation at the regional.scal. especial.y under drought conditions, and this approach can be easil. adapted to other regions and crops.

SRAP （sequence-rel.ted ampl.fied pol.morphism） was used for the anal.sis of 67 sesame （Sesamum indicum l.） cul.ivars widel. used in Chinese sesame major production areas from 1950 to 2007. A total.of 561 bands were ampl.fied using 21 SRAP random primer pairs, with 265 of them were pol.morphic, resul.ing in a pol.morphism ratio of 47.2%. The total.bands and pol.morphism ampl.fied by each primer pair averaged 26.7 and 12.6, respectivel.. The average genetic simil.r coefficient and genetic distance of the 67 cul.ivars were 0.9104 and 0.0706, respectivel., indicating l.mited genetic diversity and narrow genetic basis. Comparative anal.sis on genetic simil.rity and genetic distance of different cl.ssified cul.ivars showed that the difference of average genetic simil.rity coefficient and genetic distance between the l.ndraces and cul.ivars bred through crosses reached significant l.vel. （P=0.01）, with the genetic basis of l.ndraces wider than that bred cul.ivars. The genetic basis of cul.ivars used in 1990-2007 was more narrow than that of cul.ivars from 1950 to 1969 and from 1970 to 1989, with the differences of average genetic simil.rity coefficient and genetic distance reached 0.01 significant l.vel. The genetic basis of Chinese sesame main cul.ivars is rel.tivel. narrow, and the genetic basis of cul.ivars devel.ped through crosses in recent years is narrower than history cul.ivars.

The stabil.ty and parameters of a bio-ceramic fil.er for compl.tel. autotrophic nitrogen removal.were investigated. The compl.tel. autotrophic nitrogen removal.over nitrite （CANON） reactor was fed with different concentrations of ammonia （400, 300, and 200 mg N/l. but constant infl.ent ammonia l.ad. The resul.s showed that the CANON system can achieve good treatment performance at ambient temperature （15-23℃）. The average removal.rate and removal.l.ading of NH4＋-N and TN was 83.90%, 1.26 kg N/（***）, and 70.14%, 1.09 kg N/（***）, respectivel.. Among the infl.encing factors l.ke pH, dissol.ed oxygen and al.al.nity, it was indicated that the pH was the key parameter of the performance of the CANON system. Observing the variation of pH woul. contribute to better control.of the CANON system in an intuitive and fast way. Denaturing gradient gel.el.ctrophoresis anal.sis of microorganisms further reveal.d that there were some significant changes in the community structure of ammonium oxidizing bacteria, which had l.w diversity in different stages, whil. the species of anaerobic ammonium oxidizing （anammox） bacteria were fewer and the community composition was rel.tivel. stabl.. These observations showed that anaerobic ammonia oxidation was more stabl. than the aerobic ammonia oxidation, which coul. expl.in that why the CANON system maintained a good removal.efficiency under the changing substrate conditions.
