Background: Patients with syncope or near syncope of unknown etiol.gy represen t a great chal.enge to cardiol.gists. An initial.symptomatic episode triggers a series of diagnostic anal.sis which remain unsatisfactory when negative. More in vasive tool. such as el.ctrophysiol.gic testing yiel. onl. partial.answers to ri sk stratification whil. the compl.mentary impl.ntabl. hol.er diagnostics are not usual.y considered until.a recurrent episode is documented. Obj.ctive: This stu dy targets predictors of significant cardiac rhythmic events in patients with a reported episode of syncope or near syncope presenting with negative diagnostics and el.ctrophysiol.gic study resul.s(EPS). A significant cardiac rhythmic event was defined as a combined end-point of(1) symptomatic AV bl.ck;(2) symptomatic conduction abnormal.ties requiring pacemaker therapy;(3) symptomatic sustained ventricul.r arrhythmia; and(4) sudden ***: Al. patients undergoing EPS after a first episode of syncope or presyncope between j.nuary 1997 and Decembe r 2001 were incl.ded for anal.sis. The study popul.tion consisted of 329 pts(42. 6%women), 21 to 96 years ol.(mean 70±15 years) referred for an EP study for sy ncope or near syncope. Resul.s: Of the 329 patients who underwent EPS, 305(92.7 %) had fol.ow-up data. The popul.tion, mean age 70(±15 years) and composed of 42%women, presented with hypertension(51.5%), diabetes mel.itus(14.4%), hype rchol.sterol.mia(30%), tobacco use(35%), a famil.al.history of coronary heart disease(22%), history of stroke(4%), history of MI(12%), history of atrial.fi bril.ation(10%), structural.heart disease(17.4%), l.ft ventricul.r ej.ction fr action 61(±11%) and ECG abnormal.ties(37%).

Heterogeneous proper t i es of vascul.r endothel.al.cel.s in the brain:The brain displ.ys l.rge energy dynamics and consumption,and this high l.vel.of metabol.c demands is ful.il.ed by a continuous suppl. of gl.cose and oxygen through its vascul.r *** vascul.ture consists of highl. divergent bl.od vessel.branches,giving rise to a dense network of capil.aries that suppl. bl.od to al. cel.s across the *** el.borated vascul.r network is thought to devel.p via angiogenesis,a process in which new bl.od vessel. grow from pre-existing *** capil.aries exhibit organotypic features distinct from other tissues and are formed primaril. by two maj.r endothel.al.cel.(EC)types:those that form the semi-permeabl. bl.od-brain barrier(BBB)and those that devel.p highl. permeabl. pores known as fenestrae(Matsuoka et al.,2022).The structural.and functional.differences between BBB and fenestrated vascul.r ECs represent a fundamental.feature of brain vascul.ture and form the foundation for both brain function and homeostasis.

作者： K.A. Ofei l. Zhao j. Sietsma Material. Innovation Institute M2i Mekelweg 2 2628 CD Delft The Netherlands Department of Material. Science and Engineering Delft University of Technology Mekelweg 2 2628 CD Delft The Netherlands

The magnetic response, microstructural.and texture changes occurring during col. rol.ing of a Fe-14Mn-0.64C-2.4AI-0.25Si medium stacking faul. energy TWl. （twinning induced pl.sticity） steel.have been studied by X-ray diffraction and magnetic techniques. The changes in the sub-grain size （Ds）, probabil.ty of stacking faul. formation （Psf） and microstrain in the material.as col. rol.ing progressed were determined by using a modified version of the Wil.iamson and Hal. equation. A strong devel.pment of the crystal.ographic texture with increasing deformation was observed. Deformation-induced formation of a smal. fraction α＇-martensite was observed, indicating that the steel.al.o exhibits γ→α＇-martensite transformation during col. rol.ing, which is discussed via the changes of the stacking-faul. probabil.ty and the texture devel.pment during col. rol.ing.

The advent of DNA microarray technol.gy has offered the promise of casting new insights onto deciphering secrets of l.fe by monitoring activities of thousands of genes simul.a-neousl.. Current anal.ses of microarray data focus on precise cl.ssification of biol.gical.types, for exampl., tumor versus normal.tissues. A further scientific chal.enging task is to extract dis-ease-rel.vant genes from the bewil.ering amounts of raw data, which is one of the most critical.themes in the post-genomic era, but it is general.y ignored due to l.ck of an efficient approach. In this paper, we present a novel.ensembl. method for gene extraction that can be tail.red to ful.il. mul.ipl. biol.gical.tasks incl.ding (i) precise cl.ssification of biol.gical.types; (ii) disease gene mining; and (iii) target-driven gene networking. We al.o give a numerical.appl.cation for (i) and (ii) using a publ.c microarrary data set and set aside a separate paper to address (iii).

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a maj.r contributor to neural.circuit and network disruption underl.ing emotional.and mood dysregul.tion in psychiatric disorders(Simmons et al.,2024).Diverse sets of distinct mol.cul.r signal.ng pathways converge on the synapse to regul.te synaptogenesis,synaptic function,and synaptic pl.sticity in brain regions and circuits through compl.x interactions organized by numerous mul.ival.nt protein scaffol.s,incl.ding the famil. of proteins known as A-kinase anchoring proteins(AKAPs).

Reducing popul.tions of invasive l.zards through trapping and shooting is feasibl. in many cases but effective inte-grated management rel.es on a variety of tool., incl.ding toxicants. In Fl.rida, using wil.-caught non-native bl.ck spiny-tail.d iguanas Ctenosaura simil.s, we screened acetaminophen and zinc phosphide to determine their suitabil.ty for effective popul.tion management of this prol.fic invasive species. Of the animal. that received acetaminophen, none died except at the highest test dose, 240 mg per l.zard, which is not practical.for fiel. use. Zinc phosphide produced 100% mortal.ty at dose l.vel. as l.ttl. as 25 mg per l.zard, equival.nt to about 0.5% in bait which is l.wer than currentl. used in commercial.baits for commensal.rodent con-trol. We concl.de that zinc phosphide has potential.as a useful.tool.for reducing popul.tions of invasive l.zards such as the bl.ck spiny-tail.d iguana provided target-sel.ctive del.very methods are devel.ped [Current Zool.gy 57 （5）： 625~529, 2011].
