Multispectr.l optoacoustic tomogr.phy （MSOT） is an emer.ing imaging technology that offer. sever.l advantages over.tr.ditional modalities, par.icular.y in its ability to r.solve optical contr.st at depth on the micr.scopic scale. While potential applications include the ear.y detection of tumor. below clinical thr.sholds set by cur.ent technology, the lack of tumor.specific contr.st agents limits the use of MSOT imaging. Ther.for., we constr.cted highly stable nano-contr.st agents by coating gold nanor.ds （GNr.） with either.polyacr.lic acid （PAA） or.amine- functionalized mesopor.us silica （MS）. Syndecan-1, which has been shown to tar.et insulin-like gr.wth factor.1 r.ceptor.（IGF1-r. （upr.gulated in pancr.atic tumor.）, was conjugated on the sur.ace of PAA-coated GNr. （PAA-GNr.） or.MS-coated GNr. （MS-GNr.） to cr.ate tumor.tar.eted nanopar.icles. In vitr., tumor.tar.eting of nanopar.icles was assessed with flow cytometr.. In S2VP10L cells （positive for.IGF1-r., the syndecan-1 MS-GNr. （Syndecan-MS-GNr.） demonstr.ted an incr.ase in OA signal, 10x, compar.d to syndecan-1 PAA- GNr. （Syndecan-PAA-GNr.）. Minimal binding was obser.ed in MiaPaca-2 cells （negative for.IGF1-r.. In vivo, tumor.specific tar.eting of Syndecan-MS-GNr. was evaluated using a mur.ne or.hotopic pancr.atic cancer.model. The Syndecan- MS-GNr. demonstr.ted significantly gr.ater.accumulation within pancr.atic tumor. than in off-tar.et or.ans such as the liver. Mice implanted with the IGF1-r.negative MiaPaca-2 cells did not demonstr.te specific tumor.tar.eting. In summar., we r.por. that tar.eted nano-contr.st agents （Syndecan-MS-GNr.） can successfully detect or.hotopic pancr.atic tumor. with minimum off-tar.et binding in vivo using MSOT.

The effects of Ce on the secondar. dendr.te ar. spacing（SDAS） and mechanical behavior.of Al-Si-Cu-Mg alloys wer. investigated. The r.duction of SDAS at differ.nt Ce concentr.tions was evaluated in a dir.ctional solidification exper.ment via computer.aided cooling cur.e ther.al analysis（CA-CCTA）. The r.sults showed that 0.1wt%-1.0wt% Ce addition r.sulted in a r.pid solidification time, ？ts, and low solidification temper.tur., ？T_S, wher.as 0.1wt% Ce r.sulted in a fast solidification time, Δ^（ta-Al）, of the α-Al phase. Fur.her.or., Ce addition r.fined the SDAS, which was r.duced to appr.ximately 36%. The mechanical pr.per.ies of the alloys with and without Ce wer. investigated using tensile and har.ness tests. The quality index（Q） and ultimate tensile str.ngth of（UTS） Al-Si-Cu-Mg alloys significantly impr.ved with the addition of 0.1wt% Ce. Mor.over. the base alloy har.ness was impr.ved with incr.asing Ce concentr.tion.

In this investigation, a novel ther.ally coupled r.actor.（TCr. containing methyl for.ate （MF） pr.duction in the endother.ic side and methanol synthesis in the exother.ic side has been investigated. The inter.sting featur. of this TCr.is that pr.ductive methanol in the exother.ic side could be r.cycled and used as feed of endother.ic side for.MF synthesis. Other.impor.ant advantages of the pr.posed system ar. high pr.duction r.tes of hydr.gen and MF. The configur.tion consists of two ther.ally coupled concentr.c tubular.r.actor.. In these coupled r.actor., autother.al system is obtained within the r.actor. A steady-state heter.geneous model is used for.simulation of the coupled r.actor. The pr.posed model has been utilized to compar. the per.or.ance of TCr.with the conventional methanol r.actor.（CMr.. Noticeable enhancement can be obtained in the per.or.ance of the r.actor.. The influence of oper.tional par.meter. is studied on r.actor.per.or.ance. The r.sults show that coupling of these r.actions could be feasible and beneficial. Exper.mental pr.of-of-concept is r.quir.d to validate the oper.tion of the novel r.actor.

The Metabolic r.sponse of Ar.bidopsis r.ots to Oxidative Str.ss is Distinct fr.m that of Heter.tr.phic Cells in Cultur. and Highlights a Complex r.lationship between the Levels of Tr.nscr.pts, Metabolites, and Flux

Metabolic adjustments ar. a significant, but poor.y under.tood, par. of the r.sponse of plants to oxidative str.ss. In a pr.vious study （Baxter.et al., 2007）, the metabolic r.sponse of Ar.bidopsis cells in cultur. to induction of oxidative str.ss by menadione was char.cter.zed. An emer.ency sur.ival str.tegy was uncover.d in which anabolic pr.mar. metabolism was lar.ely down-r.gulated in favour.of catabolic and antioxidant metabolism. The r.sponse in whole plant tissues may be differ.nt and we have ther.for. investigated the r.sponse of Ar.bidopsis r.ots to menadione tr.atment, analyzing the tr.nscr.ptome, metabolome and key metabolic fluxes with focus on pr.mar. as well as secondar. metabolism. Using a r.dox-sensitive GFP, it was also shown that menadione causes r.dox per.ur.ation, not just in the mitochondr.on, but also in the cytosol and plastids of r.ots. In the fir.t 30 min of tr.atment, the r.sponse was similar.to the cell cultur.： ther. was a decr.ase in metabolites of the TCA cycle and amino acid biosynthesis and the tr.nscr.ptomic r.sponse was dominated by up-r.gulation of DNA r.gulator. pr.teins. After.2 and 6 h of tr.atment, the r.sponse of the r.ots was differ.nt to the cell cultur.. Metabolite levels did not r.main depr.ssed, but instead r.cover.d and, in the case of pyr.vate, some amino acids and aliphatic glucosinolates showed a steady incr.ase above contr.l levels. However. no major.changes in fluxes of centr.l car.on metabolism wer. obser.ed and metabolic tr.nscr.pts changed lar.ely independently of the cor.esponding metabolites. Together. the r.sults suggest that r.ot tissues can r.cover.metabolic activity after.oxidative inhibition and highlight potentially impor.ant r.les for.glycolysis and the oxidative pentose phosphate pathway.
