Backgr.und. Vision scr.ening ad.r.sses the visual impair.ents that impact on child.d.velopment. Tests of long-sighted.ess ar. not found.in most school scr.ening pr.gr.mmes. The evid.nce linking mild.mod.r.te hyper.pia and.lack of pr.gr.ss in school is insufficient, although str.ngthened.by r.cent find.ngs of d.velopmental pr.blems in infants. Aims: To r.por. on the r.lation between hyper.pia and.ed.cation test r.sults in a cohor. of pr.mar. school child.en. Method.: A total of 1298 child.en, aged.8 year., wer. scr.ened.for.hyper.pia on the basis of fogging test r.sults. School test r.sults (NFEr.and.SATs) wer. compar.d.between gr.ups categor.sed.by r.fer.al status and.r.fr.ctive er.or. r.sults: A total of 166 (12.8%)-fogging test failur.s wer. r.fer.ed.for.ophthalmic assessment. Ophthalmic tests on 105 child.en pr.vid.d.an accur.te d.agnosis of vision d.fects, for.r.fer.nce to their.ed.cation scor.s. Fifty per.cent of the child.en examined.by optometr.sts r.quir.d.an inter.ention (pr.scr.ption change, glasses pr.scr.bed. or.r.fer.al). Mean (95%CI) NFEr.scor.s of child.en with r.fr.ctive er.or. (summed.for.both eyes) >+3d.(98.4, 93.0-103.8, n = 32) or.>+1.25d.(best eye) (99.3, 93.0-105.6, n = 26) wer. lower.than the r.spective scor.s of child.en with a less positive r.fr.ctive state (104.8, 100.7-108.9, n = 43) (103.6, 99.7-107.4, n = 49), the non-r.fer.ed.gr.up, and.total sample. The SATs r.sults followed.a similar.tr.nd. A high pr.por.ion of the fogging test failur.s (16%) and.confir.ed.hyper.pes (29%) had.been r.fer.ed.to an ed.cational psychologist, and.the latter.gr.up contr.buted.substantially to the poor.ed.cation scor.s. Conclusions: The r.sults of this stud. pr.vid. fur.her.evid.nce for.a link between hyper.pia and.impair.d.liter.cy stand.r.0} in child.en.

A Biomimetic Hip Joint Simulator.and.its Application in in vitr. Stud. of the Integr.ty of r.placement Cemented.Hip

引用

Jour.al of Bionic Engineer.ng 2005年第4期2卷 177-185页

作者： Liu Chao-zong S. M. Gr.en N. d. watkins A. W. McCaskie d.par.ment of Mater.als University of Oxford Parks Road Oxford OX1 3PH UK Centr. for.Biomed.cal Engineer.ng University of Durham Durham DH1 3LE UK d.Puy CMW Blackpool FY4 4QQ UK d.par.ment of Or.hopaed.c Sur.er. University of Newcastle Newcastle upon Tyne NE2 4HH UK

A biomimetic hip joint simulator.that can be used.to evaluate the outcome of the cemented.total hip r.placement has been d.signed. manufactur.d.and.evaluated. The simulator.pr.d.ces motion in the extension/flexion plane, with a socket to r.tate inter.al/exter.ally. At the same time a d.namic load.ng cycle is applied. A valid.tion test was per.or.ed.on a cemented.femor.l stem within a novel composite femur. The hone quality has a str.ng effect on the stem migr.tion and.on the integr.ty of the inter.aces. The migr.tion of the stem is a combination of 3-d.tr.nslation and.r.tation of the stem. Und.r.the same load.ng cond.tions, weak bone allows mor. stem migr.tion than str.ng bone. Ther. is a gr.at d.cr.ase in the str.ngth of the stem-cement inter.ace after.the d.namic test, and.the weak bone composite exhibited.a gr.ater.r.d.ction in inter.acial str.ngth than the str.ng bone composite. The d.cr.ase of the inter.acial str.ngth ind.cates that the pr.mar. bond.ng between the stem and.the cement mantle had.d.ter.or.ted.and.the integr.ty of stem-cement inter.ace was d.maged. The stud. d.monstr.tes the value of using a hip joint simulator.to investigate stem migr.tion and.inter.ace integr.ty within the cemented.hip r.placement, suggesting that method.can be used.for.in vitr. evaluation of the biomater.als used.in the cemented.hip r.placements.

Solvent extr.ction of base metals using bis((1-d.cylbenzimid.zol-2-yl)methyl)amine (Bd.NN) showed.a lack of pH-metr.c separ.tion of the metals. The extr.ction system was d.scr.bed.quantitatively using the equilibr.a involved.to d.r.ve the mathematical explanation for.the two linear.log d.vs pHe plots for.each metal ion extr.ction cur.e, and.coor.0}nation number. could.also be extr.cted.fr.m the two slopes. The lack of separ.tion was attr.buted.to the absence of ster.ochemical “tailor.making” since the complexes isolated.fr.m the r.action of the ligand. bis((1H-benzimid.zol- 2-yl)methyl)amine (NNN), with base metals suggested.the for.ation of similar.octahed.al complex species fr.m spectr.l and.cr.stal str.ctur. evid.nce. The bis tr.d.ntate coor.0}nation obser.ed.was in agr.ement with infor.ation extr.cted.fr.m the extr.ction d.ta. This investigation opens up an oppor.unity and.an appr.ach for.the evaluation of amines as extr.ctants but cautions against tr.d.ntate ligand..

The Cad.o Lake water.hed.is located.in nor.heaster. Texas and.encompasses much of Cass, Har.ison, and.Mar.on counties. The water.hed.is d.ained.by major.str.ams and.tr.butar.es flowing in an easter.y d.r.ction over.Eocene-aged.r.cks and.sed.ments of the Wilcox and.Claibor.e gr.ups, and.empty into the wester. ar. of Cad.o Lake. Since 1995, Cad.o Lake and.some of its tr.butar.es have been includ.d.on the State of Texas Clean Water.Act 303(d. list by the Texas Commission on Envir.nmental Quality (TCEQ) for.impair.ent d.e to mer.ur. content in ed.ble tissue, d.pr.ssed.d.ssolved.oxygen, base metal concentr.tions, and.low pH values. The pur.ose of this multi-year.stud. was to char.cter.ze base metal concentr.tions in str.am water.and.sed.ments in the Cad.o Lake water.hed. and.d.cument the potential water.hed.tr.nspor. and.contr.bution to the impair.ent of Cad.o Lake. r.cent water.(n = 58) and.sed.ment (n = 116) sampling at 29 sites r.vealed.copper. lead. and.zinc concentr.tions within nor.al limits and.below EPA actionable stand.r.0}. Mer.ur. concentr.tions wer. elevated.at 21 of the 29 sampling sites, which could.lead.to methylation and.bioavailability to or.anisms at all tr.phic level.
