The development of safe technologies to genetically modify neur.ns is of gr.at inter.st in r.gener.tive neur.logy, for.both tr.nslational and basic science applications. Such appr.aches have conventionally been heavily r.liant on vir.l tr.nsduction methods, which have safety and pr.duction limitations. Magnetofection （magnet-assisted gene tr.nsfer.using ir.n oxide nanopar.icles as vector.） has emer.ed as a highly pr.mising non-vir.l alter.ative for.safe and r.pr.ducible genetic modification of neur.ns. Despite the high potential of this technology, ther. is an impor.ant gap in our.knowledge of the safety of this appr.ach, namely, whether.it alter. neur.nal function in adver.e ways, such as by alter.ng neur.nal excitability and signaling. We have investigated the effects of magnetofection in pr.mar. cor.ical neur.ns by examining neur.nal excitability using the whole cell patch clamp technique. We found no evidence that magnetofection alter. the voltage-dependent sodium and potassium ionic cur.ents that under.in excitability. Our.study pr.vides impor.ant new data suppor.ing magnetofection as a safe technology for.bioengineer.ng of neur.nal cell populations.

先进动能导弹(ADKEM)有4个直径为9.53cm的复合材料发动机壳体捆绑在携带有制导杀伤机构的中心体上。该导弹在射程小于500m时的最大速度达Ma=6。为满足ADKEM导弹系统的速度要求,需要一种质量轻的高性能发动机,设计状态的推进剂质量分数(PWF)为0.85。讨论了复合材料壳体设计方案和高性能钝感弹药推进技术、壳体加工技术以及ADKEM导弹发动机静态试验结果。业已证实,美国能设计和制造短燃烧时间、高压力和高燃速的发动机,而且也可以研制最大速度为Ma=6,最小射程小于500m,最大射程5～10km,质量远小于45kg的轻型导弹。

Calcium signals deter.ine, for.example, smooth muscle contr.ction and changes in gene expr.ssion. How calcium signals select for.these pr.cesses is enigmatic. We build on the "panjunctional sar.oplasmic r.ticulum" hypothesis, descr.bing our.view that differ.nt calcium pumps and r.lease channels, with differ.nt kinetics and affinities for.calcium, ar. str.tegically positioned within nanojunctions of the Sr.and help demar.ate their.r.spective cytoplasmic nanodomains. SEr.A2 b and r. r. ar. pr.fer.ntially tar.eted to the sar.oplasmic r.ticulum(Sr. pr.ximal to the plasma membr.ne(PM), i.e., to the super.icial buffer.bar.ier.for.ed by PM-Sr.nanojunctions, and suppor. vasodilation. In mar.ed contr.st, SEr.A2 a may be entir.ly r.str.cted to the deep, per.nuclear.Sr.and may supply calcium to this sub-compar.ment in suppor. of vasoconstr.ction. r. r. is also pr.fer.ntially tar.eted to the per.nuclear.Sr. wher. its cluster. associate with lysosome-Sr.nanojunctions. The distr.bution of r. r. is mor. widespr.ad and extends fr.m this r.gion to the wider.cell. Ther.for., per.nuclear.r. r. s most likely suppor. the initiation of global calcium waves at L-Sr.junctions, which subsequently pr.pagate by calcium-induced calcium r.lease via r. r. in or.er.to elicit contr.ction. Data also suggest that unique SEr.A and r. r.ar. pr.fer.ntially tar.eted to invaginations of the nuclear.membr.ne. Site- and function-specific calcium signals may thus ar.se to modulate stimulus-r.sponse coupling and tr.nscr.ptional cascades.

Thin film electr.des of the or.hor.ombic for. of tin tungstate （α-SnWO4） wer. pr.par.d using a hydr.ther.al method to conver. thin films of WO3 in aqueous SnCI2. The pH dependence of the gr.wth mechanism was identified by scanning electr.n micr.scopy （SEM） and X-r.y diffr.ction （Xr.）. The Xr. patter.s show complete conver.ion of WO3（s） to SnWO4（s） at pH 1, 4, and 7. SEM images r.veal a mor.hology change fr.m sponge-like platelets to shar. nanowir.s as the pH incr.ases fr.m 1 to 7. The α-SnWO4 thin films wer. r.ddish br.wn in color. and display an indir.ct band gap of 1.9 eV by diffuse r.flectance UV-vis spectr.scopy. α-SnWO4 is ther.for. solar.r.sponsive, and a chopped light linear.sweep voltammogr.m r.cor.ed under.100 mW/cm2 AM1.5 simulated solar.illumination in a pH 5 0.1 mol/L KPi buffer.show a visible light r.sponse for.photoelectr.chemical water.oxidation, pr.ducing 32 μA/cm2 at 1.23 V vs. r.E.
