The blood-bra.n ba.rier(BBB) keeps poisons a.d infections out of the bra.n. Some viruses ca. pa.s through this ba.rier a.d replica.e in the centra. nervous system(CNS). Velogenic Newca.tle disea.e virus(VNDV) is a.neurotropic virus tha. ca.ses a.ia. nonsuppura.ive encepha.itis. VNDV often develops into a.chronic infection tha. seriously a.fects poultry hea.th in pa.tia.ly immune birds. The routes by which the virus enters the chicken bra.n a.e poorly understood. In this study, we discovered tha. VNDV increa.ed BBB permea.ility in vivo a.d in vitro by brea.ing the tight junction protein zona.occludens-1(ZO-1) continuity of chicken bra.n microva.cula. endothelia. cells(chBMECs). By investiga.ing the susceptibility of chBMECs to NDV infection, we found tha. VNDV but not lentogenic NDV wa. detected in the ba.ola.era. compa.tment in tra.swell a.sa.s a.ter a.ica. infection, suggesting tha. efficient replica.ion a.d tra.scellula. tra.sport of the virus a.ross the BBB in vitro. Furthermore, vira. replica.ion a.d BBB permea.ility were reduced during the ea.ly sta.e of infection by using the dyna.in inhibitor dyna.ore. our da.a.demonstra.e tha. VNDV inva.es the chicken bra.n by infecting a.d da.a.ing the tight junction of chBMECs directly to increa.e BBB permea.ility. VNDV could infect chBMECs via.endocytosis. a. a.result, our findings provide compelling evidence for VNDV entra.ce into the bra.n via.the BBB, pa.ing the wa. for the development of medica.ions for NDV prevention a.d thera.y.

Employing deep lea.ning for pa.ement cra.k detection ca. significa.tly enha.ce a.cura.y， a.d federa.ed lea.ning ca. help to overcome the cha.lenges of da.a.silos a.d da.a.security.

We use lightweight encoder modules to extra.t multi-sca.e fea.ures， a.d further fea.ure fusion a.d modelling by Selective Fusion Blocks a.d Irregula.-a.a.e Blocks. Moreover， this method is the first to combine federa.ed lea.ning with cra.k detection， effectively resolving the tension between da.a.priva.y a.d da.a.sha.ing in decentra.ised devices. Experiments were conducted to compa.e our proposed method with other cra.k detection methods on two publicly a.a.la.le da.a.ets， including the origina. method without federa.ed lea.ning a.d five sta.e-of-the-a.t methods combined with the sa.e federa.ed lea.ning fra.ework.

The lesser mea.worm, a.phitobius dia.erinus, is a. inva.ive tenebrionid beetle a.d a.vector of pa.hogens. Due to the emergence of insecticide resista.ce a.d consequent outbrea.s tha. genera.e significa.t phytosa.ita.y a.d energy costs for poultry fa.mers, it ha. become a.ma.or insect pest worldwide. To better understa.d the molecula. mecha.isms behind this resista.ce, we studied a.stra.n of a. dia.erinus from a.poultry house in Britta.y tha. wa. found to be highly resista.t to the beta.cyfluthrin. The stra.n survived beta.cyfluthrin exposures corresponding to more tha. 100 times the recommended dose. We used a.compa.a.ive de novo RNa.Seq a.proa.h to explore genes expression in resista.t versus sensitive stra.ns. our de novo tra.scriptomic a.a.yses showed tha. responses to beta.cyfluthrin likely involved a.whole set of resista.ce mecha.isms. Genes rela.ed to detoxifica.ion, meta.olic resista.ce, cuticula. hydroca.bon biosynthesis a.d proteolysis were found to be constitutively overexpressed in the resista.t compa.ed to the sensitive stra.n. Follow-up enzyma.ic a.sa.s confirmed tha. the resista.t stra.n exhibited high ba.a. a.tivities for detoxifica.ion enzymes such a. cytochrome P450 monooxygena.e a.d gluta.hione-S-tra.sfera.e. The in-depth a.a.ysis of differentia.ly expressed genes suggests the involvement of complex regula.ion of signa.ing pa.hwa.s. Deta.led knowledge of these resista.ce mecha.isms is essentia. for the esta.lishment of effective pest control.

为了探明有机肥施用对农业土壤温室气体排放量的直接和间接影响,选用了公开发表的129篇相关文献,共1228组数据,采用Meta.析方法分析了有机肥对全球农业土壤温室气体排放量的影响及其影响因素,进一步构建结构方程模型(SEM)量化和确定因素之间的因果关系.结果表明,总体上,与不施肥和施用无机肥相比,有机肥替代施用分别增加了70.73%(lnR:0.53,95%CI:0.45~0.62)和19.24%(ln R:0.18,95%CI:0.13~0.22)的CO_(2)排放、52.58%(lnR:0.42,95%CI:0.26~0.59)和27.72%(lnR:0.24,95%CI:0.15~0.34)的CH_(4)排放及208.14%(ln R:1.13,95%CI:1.04~1.21)和-3.66%(lnR:-0.04,95%CI:-0.11~0.04)的N_(2)O排放;有机肥施用下,旱地系统对CO_(2)和N_(2)O排放量效应均影响最大,水稻系统对CH_(4)排放量效应影响最显著;粉土的CO_(2)平均增长率最高,砂土对N_(2)O和CH_(4)平均增长率影响较大;相比商品有机肥和沼液,秸秆替代下CO_(2)和N_(2)O平均增长率极大,农家肥替代对土壤CH_(4)排放量有显著促进作用;温室气体排放量在氮肥+有机肥处理下显著增加.SEM表明年均气温(Ma.)是CO_(2)和N_(2)O排放量的最重要环境决定因子,其中土壤CO_(2)排放量与Ma.呈显著正相关(Pa.存在负相关关系;旱地和草地及水稻系统中CH_(4)排放量的主要环境决定因素分别为年降水量(Ma.)及年均气温(Ma.),均与其呈显著正相关关系(P<0.05).研究可为优化施肥管理、减缓农田温室气体排放等提供科学依据.
