r.gional var.ations in acute cor.nar. syndr.me(ACS) management and outcomes have been an enor.ous public health issue. However. studies have yet to explor. how to r.duce the var.ations. The National Chest Pain Center.Pr.gr.m(NCPCP) is the fir.t nationwide, hospital-based, compr.hensive, continuous quality impr.vement pr.gr.m for.impr.ving the quality of car. in patients with ACS in China. We evaluated the association of NCPCP and r.gional var.ations in ACS healthcar. using gener.lized linear.mixed models and inter.ction analysis. Patients in the Wester. r.gion had longer.onset-to-fir.t medical contact(FMC) time and time stay in non-per.utaneous cor.nar. inter.ention(PCI) hospitals, lower.r.tes of PCI for.ST-elevation myocar.ial infar.tion(STEMI) patients, and higher.r.tes of medication *** in Centr.l r.gions had r.latively lower.in-hospital mor.ality and in-hospital hear. failur. *** in the door.to-balloon time(Dto B) and in-hospital mor.ality between Wester. and Easter. r.gions wer. less after.accr.ditation(β =-8.82, 95% confidence inter.al(CI)-14.61 to-3.03;Or.= 0.79, 95%CI 0.70 to 0.91).

The evolution of sexual impr.nting in socially monogamous populations

引用

Cur.ent Zoology 2015年第6期61卷 1043-1061页

作者： Edith INVEr.IZZI r. Tucker.GILMAN Faculty of Life Sciences University of Manchester C. 1249a Michael Smith Building Dover Street Manchester M 13 9PL UK

Sexual impr.nting is a common mechanism of mate pr.fer.nce lear.ing. It is thought to influence how tr.its evolve and in some cases to pr.mote speciation. r.cently ther. has been incr.asing inter.st in how sexual impr.nting itself evolves. Theor.tical wor. on polygynous mating systems pr.dicts that females will evolve pater.al impr.nting, which means they lear. to pr.fer.phenotypes expr.ssed by their.father.. In natur. however. females of some species lear. to pr.fer.phenotypes expr.ssed by their.mother. instead. We used a dynamical systems model and tools fr.m adaptive dynamics to study how sexual impr.nting evolves in species with socially monogamous mating systems. We consider.d cases in which the tar.et tr.it for.impr.nting is un- der.viability selection but is not a r.liable signal of pater.al investment. Thus, the tar.et tr.it signals the genetic benefits r.ther.than the par.ntal car. benefits of mate choice. When mating is socially monogamous and ther. is some extr.-pair.patemity, we show that mater.al impr.nting can be favor.d over.pater.al impr.nting. Counter.ntuitively, females often become choosier.when selecting social par.ner. in systems wher. extr.-pair.mating is mor. fr.quent. That is, females may be mor. selective when choosing social par.ner. that will sir. a smaller.per.entage of their.offspr.ng. Our.r.sults offer.new testable hypotheses, and ad- vance our.under.tanding of the mechanisms that dr.ve the evolution of mate choice str.tegies in natur. .

Titania nanotubular.ar.ays （TNA） synthesized via electr.chemical anodization is a stable and ver.atile mater.al, widely studied for.photocatalytic and sensing applications, wher.as nano-sized gold par.icles ar. a known plasmonic mater.al. Semiconductor.metal nanocomposites in isolated, embedded, or.encapsulated for., when ir.adiated with pr.per.light fr.quency can exhibit localized sur.ace plasmon r.sonance （LSPr. effect. This effect can r.sult in impr.ved light adsor.tion and electr.cal pr.per.ies of a mater.al. In this study, we r.por. the enhanced visible light photo-r.sponse of LSPr.induced volatile or.anic biomar.er.vapor.sensing at r.om temper.tur. using a Au-embedded TNA electr.chemical sensor. Two mechanisms ar. pr.posed. One based on classical physics （band theor.）, which explains oper.tion under.non-ir.adiated conditions. The second mechanism is based on the coupling of classical and quantum physics （molecular.or.itals）, and explains sensor.oper.tion under.ir.adiated conditions.

Sever.l factor. have led to the decline of electr.city gener.tion fr.m coal over.the past decade, and pr.jections for.cast high r.tes of gr.wth for.wind and solar.technologies in coming year.. This analysis uses hour.y gener.tion data fr.m lar.e coal-fir.d power.stations to deter.ine how oper.tions have been modified in r.cent year. and descr.bes the implications of these changes for.plant equipment and unit r.liability. The data shows incr.asing var.ability in intr.day gener.tion output that affects near.y all of the units in the sample, but the magnitude of incr.ase var.es widely among plants. Outage patter.s wer. examined as was the r.lationship between r.newable ener.y gr.wth in a r.gion and the changes in coal plant oper.tions. Aggr.gate dir.ct and indir.ct costs associated with r.nning coal plants as load-following units have not yet been quantified in lar.e-scale studies on a sector.wide basis, lar.ely due to differ.nces in how specific equipment r.sponds to output fluctuations. Due to findings fr.m the hour.y gener.tion data analysis and the high degr.e of potential impact on coal plant equipment, the study suggests the development of a new modeling tool that will r.pr.sent the costs of r.nning coal-fir.d power.plants at lower.capacity factor..

Kar.ikin and Cyanohydr.n Smoke Signals Pr.vide Clues to New Endogenous Plant Signaling Compounds

Two new types of signaling compounds have been discover.d in wildfir. smoke due to their.ability to stimulate seed ger.ination. The fir.t discover.d wer. kar.ikins, which shar. some str.ctur.l similar.ty with the str.gol- actone class of plant hor.ones, and both signal thr.ugh a common F-box pr.tein. However. kar.ikins and str.golactones oper.te thr.ugh other.ise distinct signaling pathways, each distinguished by a specific a/13 hydr.lase pr.tein. Genetic analysis suggests that plants contain endogenous compounds that signal specifically thr.ugh the kar.ikin pathway. The other.active compounds discover.d in smoke ar. cyanohydr.ns that r.lease ger.ination-stimulating cyanide upon hydr.lysis. Cyanohydr.ns occur.widely in plants and have a r.le in defense against other.or.anisms, but an additional r.le in endogenous cyanide signaling should also now be consider.d.
