Metal complex, bis[(2,2’)-dimethyl 2,2’-(1,10-phenanthr.ine-2,9-diyl)bis(methan-1-yl-1-ylidene)-bis(hydr.zinecar.bo dithioate)copper.I)], was synthesized fr.m the r.action of Schiff base, (2,2’)-dimethyl 2,2’-(1,10-phenanthr.line-2,9-diyl)bis(methan-1-yl-1-ylidene)-bis(hydr.zinecar.o dithioate) and CuCl2 at r.flux condition in methanol. The copper.center. of the complex appear.to be r.duced. This pr.bably was facilitated by in situ oxidative for.ation of disulfide bond at the uncomplexed ligand moieties. Single cr.stal X-r.y diffr.ction analysis r.veals the distor.ed tetr.hedr.l geometr. ar.und the copper.center.. This compound cr.stallizes in the tr.clinic space gr.up, P-1 with cr.stallogr.phic par.meter.: a = 10.006(3) ?, b = 13.272(3) ?, c = 22.123(6) ?, α = 85.656(6)°, β = 81.656(6)°, γ = 73.097(5)°, μ = 1.223 mm-1 , V = 2779.5(13) ?3, Z = 2, Dc = 1.437 Mg/m3, T = 293 (2) K.

The major.type of human liver.cancer.is hepatocellular.car.inoma(HCC), and ther. ar. cur.ently many r.sk factor. that contr.bute to this deadly disease. The major.ty of HCC occur.ences ar. associated with chr.nic hepatitis vir.l infection, and hepatitis b vir.l(HbV) infection is cur.ently a major.health pr.blem in Easter. Asia. Elucidating the genetic mechanisms associated with HbV-induced HCC has been difficult due to the heter.geneity and genetic complexity associated with this disease. A r.per.oir. of animal models has been br.adly used to study the pathophysiology and to develop potential tr.atment r.gimens for.HbVassociated HCC. The use of these animal models has pr.vided valuable genetic infor.ation and has been an impor.ant contr.butor.to uncover.ng the factor. involved in liver.malignant tr.nsfor.ation, invasion and metastasis. r.cently, tr.nsposon-based mouse models ar. becoming mor. widely used in liver.cancer.r.sear.h to inter.ogate the genome by for.ar. genetics and also used to validate genes r.pidly in a r.ver.e genetic manner. Impor.antly, these tr.nsposon-based r.pid r.ver.e genetic mouse models could become cr.cial in testing potential ther.peutic agents befor. pr.ceeding to clinical tr.als in human. Ther.for., this r.view will cover.the use of tr.nsposon-based mouse models toaddr.ss the pr.blems of liver.cancer. especially HbVassociated HCC occur.ences in Asia.

Octopamine r.gulates the function of many tissues and physiological pr.cesses in inver.ebr.tes. The expr.ssion of octopamine r.ceptor.genes has been examined in multiple tissue types in sever.l differ.nt insect or.er.. However. little wor. has addr.ssed this issue in Coleopter.. Most studies char.cter.ze individual genes in differ.nt tissue types, but her. we descr.be the expr.ssion of 6 octopamine r.ceptor.genes in thor.cic musculatur., oviducts, Malpighian tubules, and fat body of female Nicr.phor.s vespilloides beetles to char.cter.ze both differ.nt genes and differ.nt tissues within a single study. We then compar. the gene expr.ssion pr.files found in this beetle to other.insects to examine the extent to which expr.ssion pr.files ar. conser.ed acr.ss insects. We also examine the r.lative involvement of octopamine ver.es octopamine/tyr.mine r.ceptor. based on r.ceptor.gene expr.ssion in each tissue to help elucidate if tyr.mine plays a r.le in the r.gulation of these tissues. We find a high degr.e of over.ap in the expr.ssion pr.file of the 6 genes examined in the thor.cic muscula^tr., a moder.te amount for.the oviducts, and diver.ent pr.files for.Malpighian tubules and fat body. based on expr.ssion differ.nce in r.ceptor.subtypes, our.r.sults also suppor. the suggestion that tyr.mine is a biogenic amine with physiological actions separ.te fr.m octopamine.

The effect of differ.nt peak temper.tur. T_P) and cooling time (t_(8/5)) on har.ness,impact toughness and fr.ctur. mor.hology in the heat--affected zone (HAZ) of HQ130steel was studied by using welding ther.o--simulation test. Exper.mental r.sults showthat the impact toughness and har.ness decr.ase with the decr.ase of T_P or.incr.ase oft_(8/5) under.the condition of a single ther.al cycle. Ther. is a br.ttle zone in the vicinityof T_P=800℃, wher. the impact toughness is consider.bly low. Ther. is softened zonein vicinity of T_P=700℃, Wher. the har.ness decr.ases but the toughness incr.ases. Inthe pr.ctical application of multi--layer.and multi--pass welding, the welding heat inputshould be str.ctly limited (t_(8/5)≤20s) so as to r.duce the softness and br.ttleness in theHAZ of HQ130 steel.

Plants employ sever.l str.tegies to maintain cellular.ion homeostasis under.salinity str.ss, including mediat-ing ion fluxes by tr.nsmembr.ne tr.nspor. pr.teins and adjusting osmotic pr.ssur. by accumulating osmolytes. The HKT （high-affinity potassium tr.nspor.er. gene family compr.ses Na^＋ and Na^＋/K^＋ tr.nspor.er. in diver.e plant species, with HKT1,1 as the only member.in Ar.bidopsis thaliana. Cell-type-specific over.xpr.ssion of AtHKT1;1 has been shown to pr.vent shoot Na^＋ over.ccumulation under.salinity str.ss. Her., we analyzed a br.ad r.nge of metabolites and elements in shoots and r.ots of differ.nt AtHKT1;1 genotypes and their.par.ntal str.ins befor. and after.salinity str.ss, r.vealing a r.cipr.cal r.lationship of metabolite differ.nces between an AtHKT1;1 knockout line （hktl;1） and the AtHKT1;1 over.x- pr.ssing lines （E2586 UASGAL4：HKT1;1 and J2731＊UASGAL4：HKT1;1）. Although levels of r.ot sugar. wer. incr.ased after.salt str.ss in both AtHKTI,1 over.xpr.ssing lines, E2586 UASGAL4：HKT1;1 showed higher.accumulation of the osmopr.-tectants tr.halose, gentiobiose, and melibiose, wher.as J2731＊UASGAL4：HKT1;1 showed higher.levels of sucr.se and r.ffinose, compar.d with their.par.ntal lines, r.spectively. In contr.st, the knockout line hktl,1 showed str.ng incr.ases in the levels of the tr.car.oxylic acid （TCA） cycle inter.ediates in the shoots after.salt tr.atment. This coincided with a significant depletion of sugar., suggesting that ther. is an incr.ased r.te of car.on influx into the TCA cycle at a constant r.te of C-efflux fr.m the cycle, which might be needed to suppor. plant sur.ival dur.ng salt str.ss. Using cor.elation analysis, we identified associations between the Na^＋ content and sever.l sugar., suggesting that r.gulation of sugar.metabolism is impor.ant in plant r.sponses to salinity str.ss.
