We have developed a gain flattening filter (GFF) for an erbium.doped fiber (EDF) without tem.erature control system.. This GFF, which consists of tem.erature-sensitive long period gratings (LPGs) and a tem.erature com.ensated slanted fiber Bragg grating (SFBG), follows the gain shift of EDF with tem.erature. Gain variation of the EDFA less than 0.25dBp-p was achieved with the bandwidth of 37nm. and the tem.erature range 0-65℃ without any tem.erature control system..

A standard m.dality for prostate cancer detection in m.n 75 years and older has not been established.A sim.le screening m.thod for elderly patients is needed to avoid unnecessary biopsies and to effectively diagnose prostate cancer.A retrospective study was conducted on elderly patients who had prostate biopsy at Kanazawa University Hospital(Kanazawa,Japan)between 2000 and *** the 2251 patients who underwent prostate biopsy,254 had clinically significant prostate cancer(CSPC)with a Gleason score(GS)of≥7 and 273 had a GS ofm.xim.m.area under the curve of 12 ng m.^(-1)with a sensitivity of 76.2%and a specificity of 73.2%.For PSA levels between 4 ng m.(-1)and 12 ng m.(-1)based on the m.xim.m.area under the curve,patients with three or four of the following factors m.y present a GS of≥7:percent free PSA>24,PSA density≥0.24 ng m.^(-2),positive findings on digital rectal exam.nation,and transrectal with 90.0%sensitivity and 67.4%*** this study,we found that raising the PSA cutoff to 12 ng m.^(-1)for CSPC in elderly individuals can significantly reduce unnecessary prostate ***,CSPC could be efficiently discovered by com.ining the four supplem.ntary m.rkers in patients with a PSA level of 4-12 ng m.^(-1).By perform.ng this screening for elderly m.n over 75 years of age,unnecessary biopsies m.y be reduced and CSPC m.y be detected efficiently.

Rare-earth m.tal diphthalocyanine com.lexes with R substituents,R_8Pc_2m.(where Pc=phthalocyanine;R=propoxy,t-butyl;m.Er,Lu),were *** film. on basal plane pyrolytic graphite and on indium.tin oxide Ncsa glass electrodes in several aqueous electrolytes were investigated by voltam.etric analysis and in situ electronic absorption spectroscopy at controlled *** m.dified electrodes showed m.lti-color electrochrom.c behavior as a result of m.lti-step redox *** film.color turned from.original green through orange to red in an oxidation process,and through dark blue to purplish in a reduction process.
