The aim of.this.paper is.to inves.igate the inf.uence of.phys.cal and chemical f.ctors.on trans.ort and us. of.s.bs.rate f.r Atta s.xdens.rubropilos. workers. Three types.of.rectangular f.agments.were us.d to s.udy the phys.cal inf.uence f.ctors. f.lter paper with paraf.in, f.lter paper without paraf.in and polyes.er f.lm. To s.udy the chemical f.ctors. s.me f.agments.were impregnated with organic extract of.orange albedo, others.were s.aked with s.ybean oil and f.r the remaining ones.nothing was.applied. The f.nowing parameters.were evaluated：（i） attractivenes. of.s.bs.rate f.r trans.ort and number of.loading workers.per treatment; （ii） f.raged material incorporation; （iii） rejection by numbers.of.f.agments.depos.ted in the garbage or bes.de the f.ngus.garden. All the polyes.er f.lm f.agments.carried out to the f.ngus.garden were s.bs.quently rejected. We verif.ed that chemical f.ctors.of.the s.bs.rate were more quickly detected by the workers. whereas.phys.cal f.ctors.were us.d as.a criterion in the decis.on-making to reject or accept the s.bs.rate collected.

We s.udied the proces. of.of.s.ring production in queenles. colonies.of.Acromyrmex s.bterraneus.brunneus. and particularly evaluated the ovary development of.workers.as.a f.nction of.their age. f.r this. s.bcolonies.were s.t up and evaluated at dif.erent periods.of.is.lation f.om the queen （2, 4 and 6 months., bes.des.individually labeled age groups. The s.bcolonies.were as.es.ed according to of.s.ring production and ovaries.containing oocytes.or not. The evaluations.s.owed worker ovipos.tion and development of.males.originating f.om worker-laid eggs. At 2 months. abs.nce of.the queen, eggs.and larvae were f.und, with eggs.in a higher proportion than larvae. Af.er 4 months. the proportion of.eggs.had reduced while larvae had increas.d, and a pupa was.f.und in one s.bcolony. At 6 months. bes.des.a higher s.are of.larvae, one pupa and one adult male were f.und. Dis.ection of.workers.revealed ovaries.containing oocytes.during the periods.of.evaluation. Only a group of.medium-s.zed and large workers. 23.3%, 20.9% and 37.5% of.the population f.om each period as.es.ed in queenles. s.bcolonies.res.ectively, pres.nted developed oocytes.in the ovary. The s.me was.obs.rved in colonies.with a queen, with 17.6%, 19.6% and 7.8% of.the group of.dis.ected workers.f.om each time period, res.ectively. With res.ect to worker age, we obs.rved by dis.ection of.the ovary, that the greates. percentage of.individuals.with ovarioles.containing oocytes.occurred at 45 days.（6 weeks. up to 90 days.（12 weeks.. Thes. res.lts.probably are as.ociated with the workers.reproduction and the laying of.trophic and reproductive eggs.in colonies.with and without a queen; thes. eggs.have dis.inct f.nctions.in each s.tuation.

Though poorly s.udied, s.nd is.an environment with an extended degree of.interaction with man. Enterococcal s.rains.can be f.und in s.nd but we do not know to what extent thes. ubiquitous.opportunis.ic nos.comial pathogens.is.lated f.om s.nd carry antimicrobial res.s.ances.and virulence traits. In an attempt to f.ll in this.knowledge gap, two dis.inct types.of.s.nd (beach and children playground) were examined concerning compos.tion in enterococcal s.ecies. genetic divers.ty of.is.lates.and abundance of.res.s.ance to antimicrobials.and virulence traits. f.ve dif.erent s.ecies.were f.und, namely Enterococcus.f.ecium, Enterococcus.f.ecalis. Enterococcus.hirae, Enterococcus.f.aves.ens.and Enterococcus.cas.elif.avus. Although genetic divers.ty was.evident, two dif.erent E. f.ecium clones. common to the two types.of.s.nd, were detected, s.gges.ing the exis.ence of.clones.well adapted to this.s.ecif.c environment or f.om a common s.urce. E. f.ecium was.as.ociated with multiple antibiotic res.s.ances. including to f.uoroquinolones.and tetracycline that are commonly us.d by veterinarians.and clinicians. Among the multires.s.ant E. f.ecium s.rains.f.om beach s.nd, two were f.om s.quence type (s.) 442, which belongs.to the wide-s.read Hos.ital-adapted clade CC17. They both carried the es. gene and the genomic is.and as.ociated with CC17. The other virulence f.ctors.s.reened were dis.eminated among E. f.ecalis.s.rains. but s.ldom detected in the other s.ecies. evidencing the exis.ence, in thes. environments. of.E. f.ecalis.s.rains.carrying the s.me virulence f.ctors.as.the clinical ones. The pres.nt work thus.s.res.es.the need to f.llow-up the pres.nce and characterization of.enterococcal s.rains.f.om both beach and children playground s.nds.and of.including thes. environments.in the epidemiological global analys.s.of.enterococcal is.lates.

Many neurodegenerative dis.as.s. including Alzheimer’s.dis.as. and Parkins.n’s.dis.as., are characteris.d by the accumulation of.mis.0}lded protein depos.ts.in the brain, leading to a progres.ive des.abilis.tion of.the neuronal network and neuronal death. Among the proteins.that can abnormally accumulate are tau and α-s.nuclein, which can propagate in a prion-like manner and which upon aggregation, repres.nt the mos. common intracellular proteinaceous.les.ons.as.ociated with neurodegeneration. f.r years.it was.thought that thes. intracellular proteins.and their accumulation had no immediate relations.ip with extracellular homeos.as.s.pathways.s.ch as.the glymphatic clearance s.s.em;however, mounting evidence has.now s.gges.ed that this.is.not the cas.. The involvement of.the glymphatic s.s.em in neurodegenerative dis.as. is.yet to be f.lly def.ned;however, it is.becoming increas.ngly clear that this.pathway contributes.to parenchymal s.lute clearance. Importantly, recent data s.ow that proteins.prone to intracellular accumulation are s.bject to glymphatic clearance, s.gges.ing that this.s.s.em plays.a key role in many neurological dis.rders. In this.review, we provide a background on the biology of.tau and α-s.nuclein and dis.us. the lates. f.ndings.on the cell-to-cell propagation mechanis.s.of.thes. proteins. Importantly, we dis.us. recent data demons.rating that manipulation of.the glymphatic s.s.em may have the potential to alleviate and reduce pathogenic accumulation of.propagation-prone intracellular cytotoxic proteins. f.rthermore, we will allude to the lates. potential therapeutic opportunities.targeting the glymphatic s.s.em that might have an impact as.dis.as. modif.ers.in neurodegenerative dis.as.s.
