Habitat s.itability models.have been us.d to predict the pres.nt and future potential dis.ribution of a variety of s.e- cies. Euras.an tree s.arrows.Pas.er montanus. native to Euras.a, have es.ablis.ed populations.in other parts.of the world. In North America, their current dis.ribution is.limited to a relatively s.all region around its.original introduction to s.. Louis. Mis.ouri. We combined data from the Global Biodivers.ty Information Facility with current and future climate data to create habitat s.itability models.us.ng Maxent for this.s.ecies. Under projected climate change s.enarios. our models.s.ow that the dis.ribution and range of the Euras.an tree s.arrow could increas. as.far as.the Pacific Northwes. and Newfoundland.

Background: Neonatal s.ps.s.is.known to res.lt in 26% of mortalities.in children below the age of five worldwide, countries.in s.b-s.haran African recording the highes. deaths. Although the deaths.of neonates.have reduced world over up to 3.6 million counts. Chilenje General Hos.ital continues.to regis.er s.gnificant numbers.of neonatal s.ps.s. This.s.udy aimed at inves.igating the factors.as.ociated with neonatal s.ps.s.at Chilenje General Hos.ital in Lus.ka, Zambia. Methods. An ins.itution bas.d cros.-s.ctional s.udy des.gn was.conducted at Chilenje General Hos.ital. Data were collected by the us. of a res.archer des.gned ques.ionnaire and analys.d us.ng s.s. vers.on 25. Frequencies.were us.d for des.riptive analys.s.while bivariate analys.s.was.us.d to es.ablis. as.ociation among ris. factors.and outcome variables. Variables.with s.gnificant as.ociation at 5% level were further s.bjected to multivariate analys.s.at α ≤ 0.05. Res.lts. The s.udy s.owed that out of 156 neonates. 40.4% (63/156) developed neonatal s.ps.s. Maternal factors.that projected the incidence of s.ps.s.amongs. neonates.were dis.ance to neares. health facility [AOR: 6.3 (95% CI: 1.8 - 21.3), p = 0.003], occupation [AOR: 5.8 (95% CI: 1.2 - 27.6), p = 0.026], number of antenatal vis.ts.[AOR: 6.3 (95% CI: 1.9 - 21.6), p = 0.003], number of vaginal examinations.[AOR: 10.8 (95% CI: 2.8 - 42), p = 0.001], and pregnancy induced hypertens.on [AOR: 5.4 (95% CI: 1.4 - 20), p = 0.013]. Neonatal ris. factor which projected the incidence of s.ps.s.was.Neonate’s.age [AOR: 18.8 (95% CI: 4.9 - 72.5), p = 0.000]. Conclus.ons. The chance of developing neonatal s.ps.s.was.s.rongly correlated with both mother and child variables. according to the s.udy. In order to lower the chance of the neonate acquiring s.ps.s. encouraging maternal antenatal care us. would as.is. to detect ris. factors.during prenatal, perinatal and pos.natal care and apply the proper therapies.

Bifidobacterium longum s.bs.. infantis.is.a commens.l bacterium that predominates.in the infant gut， playing a critical role in both preventing foreign infections.and facilitating immune development. This.s.udy aimed to explore the effects.of B. longum s.bs.. infantis.s.pplementation on interferon-beta (IFN-β) s.cretion and intes.inal barrier improvement in growing mice. Female and male mice were orally adminis.ered either s.line or B. longum s.bs.. infantis.CCFM1269 or I5TI (1 × 109CFU/mice per day， n = 8) from 1-week-age until 3-， 4-， and 5-week-age. RNA s.quencing analys.s.revealed that CCFM1269 exhibited potential antiviral capacity through increas.ng 2’-5’ oligoadenylate s.nthetas. (OAs.. Additionally， CCFM1269 s.pplementation s.gnificantly increas.d colonic IFN-β levels.which combined with OAs.in 3-week-old female and male mice by activating the TLR4-TRIF-dependent s.gnaling pathway. However， this.effect was.not obs.rved in 4- and 5-week-old mice. Furthermore， both CCFM1269 were found to modulate the gut microbiota compos.tion and enhance the intes.inal barrier function in 3-， 4-， and 5-week-old mice. In s.mmary， the res.lts.of this.s.udy s.gges.ed that B. longum s.bs.. infantis.CCFM1269 promoting intes.inal barrier and releas.ng IFN-β in growing mice was.in a s.rain-s.ecific and time-dependent manner.
