EMi.ECTOMY FOR THE TREATMENT OF HABi.UAL ANTERi.R Di.LOCATi.N OF THE TMJ: TWO CASES REPORTS

＜正＞Satoyama coppi.e forests and terraced fi.lds hi.tori.ally produced fi.ewood, charcoal and food, and thus they mai.tai.ed vari.ty of flora and fauna, and kept attracti.e cultural landscape. However, they are seri.usly losi.g such a scenery and bi.-di.ersi.y due to the lack of management by labor shortage and the prevalence of fossi. fuel. *** and Hi.eshi.a i.land were chosen to clari.y the transi.i.n i. the land-use and vegetati.n. The both si.es are located on the shore i. the northern Kyushu and faced to i.portant poi.ts for trade and cultural exchange wi.h Chi.a and Korea i. order to make the di.ferences clearer, we used aeri.l photos taken i. di.ferent ti.es. As the result, i. became apparent that the land-use and vegetati.n changed consi.erably duri.g the peri.d between 1974 and 2002, compared to 1945. i. Hi.ama, although there were many terraced orange groves i. 1974, they were hardly seen i. 2002 whi.h seems to have been replaced by wi.e spread of bamboo forests. Such a change can be suggested as below;the orange trade deregulati.n i. the late 1970s made i. di.fi.ult to manage the groves and consequently forced to abandon the land. At the same ti.e, bamboo forests were also abandoned due to the lack of role as li.i.g and housi.g materi.ls and thus began overgrow. From the fi.ld i.vesti.ati.n, i. became apparent that bamboo i.vaded even the broad leaved forests. i. addi.i.n, the Satoyama coppi.e forests whi.h have been abandoned for more than 40 years showed the natural successi.n i. whi.h the deci.uous trees became stunt and decreased contrary to the vi.orous broadleaved evergreen trees growth. i. Hi.eshi.a, we observed the drasti. landscape change as such the terraced fi.lds once stretched from seashore to the summi. of the i.land have almost di.appeared and transformed i.to shrubby forests and bamboo forests due to the populati.n decrease and agi.g. i. the above si.uati.n, the local people organi.ed the Hi.ama Satoyama Forest Conservati.n Group fi.e

Di.er plays a central role i. RNA i.terference pathways by cleavi.g double stranded RNAs(dsRNAs) to produce small regulatory RNAs. Human Di.er can process both long double-stranded and hai.pi. precursor RNAs to yi.ld short i.terferi.g RNAs(si.NAs) or mi.roRNAs(mi.NAs), respecti.ely. Previ.us studi.s have shown that pre-mi.NAs are cleaved much more rapi.ly than pre-si.NAs i. vi.ro and are the predomi.ant natural Di.er substrates i. cells. We have used cryo-electron mi.roscopy and si.gle parti.le analysi. of Di.er-RNA complexes to gai. i.si.ht i.to the structural basi. for human Di.er’s substrate preference. Our studi.s show that Di.er has a flexi.le archi.ecture that traps pre-si.NA molecules i. a non-producti.e conformati.n. i.teracti.ns of Di.er wi.h pre-mi.NAs and dsRNA bi.di.g protei.s i.duce structural changes i. the enzyme that enable producti.e substrate recogni.i.n i. the central catalyti. channel. These fi.di.gs i.pli.ate RNA structure and cofactors i. determi.i.g substrate recogni.i.n and processi.g effi.i.ncy by human Di.er.

研究了羧酸,诸如甲酸、氯乙酸、乙酸、丙酸、丁酸和已酸,对于用苯酰三氟丙酮萃取铕的影响。由于在有机相中金属螯合物与羧酸形成加合物使萃取加强,然而在水相中,由于与羧酸的阴离子形成金属络离子防碍了萃取。已酸起有机路易斯硷的作用,并显示出协合作用,但甲酸和氯乙酸却具有掩蔽效应。乙酸、丙酸和丁酸在有机相中起协合剂作用,同时在水相中起掩蔽作用。已酸比正已醇生成更稳定的加合物,而且这种螯合加合物的组成估计是 En（BFA）3·2CH3（CH2）4COOH。

Purpose: Addi.i.nal analyses of outcomes of laser-assi.ted subepi.heli.l keratectomy (LASEK) are sti.l necessary to i.prove the safety of LASEK. Therefore, i. our study, outcomes were assessed retrospecti.ely i. 561 eyes that underwent LASEK treatment. Methods: Uncorrected vi.ual acui.y (UCVA), best spectacle-corrected vi.ual acui.y (BSCVA) and resi.ual spheri.al equi.alent were analyzed at 3 and 6 months postoperati.ely. We assessed four subgroups based on the degree of preoperati.e myopi. consi.eri.g mean BSCVA and loss of two or more li.es. Results: Mean UCVAs and BSCVAs were obtai.ed at 3 and 6 months postoperati.ely (1.23/1.35 and 1.23/1.37, respecti.ely). The mean predi.tabi.i.y was wi.hi. ±0.125 di.pters. Conversely, the safety i.dexes were 0.94 and 0.96 respecti.ely, and the effi.acy i.dexes were 0.86 and 0.86 at 3 and 6 months postoperati.ely, respecti.ely. 8.4% eyes and 5.2% eyes lost two or more li.es of BSCVA at 3 and 6 months postoperati.ely, respecti.ely. The mean BSCVAs of the hi.h or ultra-hi.h groups were si.ni.i.antly lower than those of the low or mi.d groups both 3 months and 6 months postoperati.ely. The i.ci.ence rates of losi.g two or more li.es of BSCVA i. the hi.h or ultra-hi.h myopi. groups were si.ni.i.antly greater than i. the low or mi.d groups at 3 months and 6 months postoperati.ely. Conclusi.n: LASEK predi.tably corrected myopi. achi.vi.g >1.2 i. UCVA and BSCVA. However, the safety and effi.acy i.dexes were i.h were related to the loss of two or more li.es of BSCVA. Si.ce the i.ci.ence rates of losi.g two or more li.es of BSCVA were greater i. the hi.h or ultra-hi.h myopi. groups, we consi.er LASEK as more safely performed i. pati.nts wi.h low to mi.d preoperati.e myopi..
