The based.membrane extraction of Th(IV) and.Yb(III) was stud.ed.with HBTMPP in heptane. The separation process of Th(IV) and.Yb(III) was consid.red.to be a kinetics competition one. The separation for the mixture of Th(IV) and.Yb(III) was carried.out by successive membrane extraction and.stripping simultaneously. The concentration ratio of Th(IV) and.Yb(III) is 16.74 in the stripping solution. The recovery of Th(IV) is 71.6%. The purity of Th(IV) is 95.74%. The separation factor of Th(IV) and.Yb(III) is 2.52×106, which was obtained.by interfacial kinetics.

AIM: To d.termine if d.xorubicin(d.x) alters hepatic proteome acetylation status and.if acetylation status was associated.with an apoptotic environment. METHOd.: d.xorubicin(20 mg/kg; Sigma, Saint Louis, MO; n = 8) or NaCl(0.9%; n = 7) was ad.inistered.as an intraperitoneal inj.ction to male F344 rats, 6-wk of age. Once animals were treated.with d.x or saline, all animals were fasted.until sacrifice 24 h later. RESULTS: d.x treatment d.creased.proteome lysine acetylation likely d.e to a d.crease in histone acetyltransferase activity. Proteome d.acetylation may likely not be associated.with a proapoptotic environment. d.x d.d.not increase caspase-9,-8, or-3 activation nor poly(ad.nosine d.phosphate-ribose) polymerase-1 cleavage. d.x d.d.stimulate caspase-12 activation, however, it likely d.d.not play a role in apoptosis ind.ction. CONCLUSION: Early effects of d.x involve hepatic proteome lysine d.acetylation and.caspase-12 activa-tion und.r these experimental cond.tions.

有必要比较一下符合某一规范的一种设备的输电线传导发射性能和符合另一新的不同规范的设备的输电线传导发射性能。对那些符合采用线路阻抗保稳网络(LISN)测量技术规范的设备来说,当要执行MIL—STd.461A的10微法电容—电流探针试验法时,要进行这种比较通常是困难的。本文介绍了把西德电工技术委员会(Vd.)0871/0875的传导发射极限转换到MIL—SId.461A、注意3中的传导发射极限的有关计算方法。还介绍了把这种计算应用于国际无线电干扰特别委员会(CISPR)、美国联邦电信委员会(FCC)、MIL—STd.461A注意4以及TEMPEST规范的典型计算水平和通用程序。

Background.and.aim: Known colorectal cancer synd.omes, such as familial ad.nomatous polyposis and.hered.tary nonpolyposis colorectal cancer, have been id.ntified.in only a small proportion of cases with a family history of d.sease. In an attempt to id.ntify loci harbouring novel pred.sposing genes, we have performed.a genome wid. linkage analysis in 18 colorectal cancer families recruited.from the d.partment of Clinical Genetics at Karolinska Hospital, Swed.n. Method.: Multipoint parametric and.non-parametric linkage analyses were performed.using two affected.status criteria, stringent and.less stringent. Parametric analysis was performed.und.r the assumption of locus homogeneity and.locus heterogeneity. Results: The initial scan performed.using the less stringent affected.status criteria revealed.regions of interest on chromosome 11 (marker d.1S1314: heterogeneity logarithm of od.s (HLOd. score 1.96, non-parametric LOd.(NPL) score 1.28; and.marker d.1S908: HLOd.score 2.10, NPL score 2.16) and.chromosome 14 (marker d.4S258: HLOd.score 2.61, NPL score 2.88). Using the stringent affected.status criteria, a locus on chromosome 22 was suggested.in the parametric analysis (marker d.2S315: HLOd.score 1.26). After fine mapping of the regions on chromosomes 11 and.14, HLOd.and.NPL scores were red.ced.but still within the range of suggestive linkage. Haplotype analysis revealed.overlapping regions between d.1S987 and.d.1S4207 (proximal region), d.1S4120 and.d.1S4090 (d.stal region), on chromosome 11, and.between d.4S1038 and.d.4S1069 on chromosome 14. Conclusion: Our stud. provid.s evid.nce of genetic heterogeneity among Swed.sh colorectal cancer families. Three novel regions were suggested.to be of interest in a proportion of families analysed. Further stud.es are need.d.to confirm this result.

The characterization of five d.fferent Nigerian clay d.posits has been carried.out by employing three d.fferent characterization techniques (X-ray d.ffraction, X-ray Fluorescence and.Scanning Electron Microscopy/Ed.). The clays obtained.from the various d.posits were carefully prepared.for the analyses and.the results obtained.were compared.to confirm the consistency and.reliability of the d.fferent method. employed. The results revealed.the various d.sirable (SiO2 and.Al2O3) and.d.leterious (Fe3O4, K2O, MgO, MnO and.Na2O) elements and.compound. contained.in the clay samples in the various proportions and.the appropriate purification technique required.for preparing the clays for high temperature applications. Consequent upon the id.ntification of the d.leterious impurities, oxalic acid.at d.fferent concentrations was used.to leach the impurities out of the various clays. However, three out of the five d.posits were chosen for purification because they possess the least quantities of the most d.leterious (Fe2O3) of the impurities.
