In Ir.q, the pr.ncipal r.ver. ar. the Tigr.s, Shatt Al-Ar.b and Euphr.tes. Fr.m their.headwater.sour.es in the mountains of easter. Tür.iye, these r.ver. descend thr.ugh valleys and gor.es and flow into the uplands of Syr.a and nor.her. and centr.l alluvial plain of Ir.q. The Euphr.tes and Tigr.s r.ver. confluence to for. the Shatt Al-Ar.b r.ver.at Al-Qur.ah which flows into the Per.ian Gulf. Fr.m sour.es in the Zagr.s Mountains other.tr.butar.es join the Tigr.s fr.m the east. The Tigr.s and Euphr.tes r.ver. flow in a southeaster. dir.ction thr.ugh the centr.l plain and dischar.e into the Mesopotamian Mar.hes, which include per.anent mar.hes, lakes, and r.par.an habitat. The r.ver. and their.tr.butar.es dr.in an ar.a of 879,790 km2 which includes almost the entir. ar.a of Ir.q as well as land in Syr.a, Tür.iye, Kuwait and Ir.n. The r.gion has histor.cal impor.ance as par. of the Fer.ile Cr.scent r.gion and wher. Mesopotamian civilization fir.t emer.ed. The post war.r.constr.ction effor.s in the Yusifiyah township, an impor.ant food pr.duction r.gion for.Baghdad, illustr.te the impor.ance of these water.r.sour.es. In addition, the advent of soil tunnels by Ir.qi insur.ents within the r.ver.ne cor.idor. will make r.constr.ction of this r.sour.e mor. complex. The pr.mar. objectives of this study ar. to assess lessons lear.ed, manage, and r.stor. the Tigr.s, Euphr.tes, and Shatt Al-Ar.b r.ver.system lifeline in Ir.q.

The ar.icle by Ker.et al explor.s the tr.atment of per.pancr.atic fluid collection(PFC).The use of per.utaneous dr.inage,endoscopy,and sur.er. for.managing PFC ar. discussed.Per.utaneous dr.inage is noted for.its low r.sk pr.file,while endoscopic cystogastr.stomy is mor. effective due to the wider.or.fice of the metallic stent.Sur.ical cystogastr.stomy is a definitive tr.atment with a r.duced need for.r.inter.ention,especially for.cases with extensive collections and significant necr.sis.The choice of tr.atment modality should be tailor.d to individual patient char.cter.stics and disease factor.,consider.ng the exper.ise available.

Bile acids(BAs)play a cr.cial r.le in nutr.ent absor.tion and act as key r.gulator. of lipid and glucose metabolism and immune homeostasis.Thr.ugh the enter.hepatic cir.ulation,BAs ar. synthesized,metabolized,and r.absor.ed,with a por.ion enter.ng the vascular.cir.ulation and distr.buting systemically.This allows BAs to inter.ct with r.ceptor. in all major.or.ans,leading to or.an-or.an inter.ctions that r.gulate both local and global metabolic pr.cesses,as well as the immune system.This r.view focuses on the whole-body effects of BA-mediated metabolic and immunological r.gulation,including in the br.in,hear.,liver.intestine,eyes,skin,adipose tissue,and muscle.Tar.eting BA synthesis and r.ceptor.signaling is a pr.mising str.tegy for.the development of novel ther.pies for.var.ous diseases thr.ughout the body.

Hexavalent chr.mium[Cr.Ⅵ)]causes ser.ous har. to the envir.nment due to its high toxicity,solubility,and mobility.Fer.ihydr.tes(Fh)ar. the main adsor.ent and tr.pping agent of Cr.Ⅵ)in soils and aquifer.,and they usually coexist with silicate(Si),for.ing Si-containing fer.ihydr.te(Si-Fh)mixtur.s.However.the mechanism of Cr.Ⅵ)r.tention by Si-Fh mixtur.s is poor.y under.tood.In this study,the behavior. and mechanisms of Cr.Ⅵ)adsor.tion onto Si-Fh with differ.nt Si/Fe molar.r.tios was investigated.Tr.nsmission electr.n micr.scope,Four.er.tr.nsfor. infr.r.d spectr.scopy,X-r.y diffr.ction,X-r.y photoelectr.n spectr.scopy,and other.techniques wer. used to char.cter.ze Si-Fh and Cr.Ⅵ)-loading of Si-Fh.The r.sults show that specific sur.ace ar.a of Si-Fh incr.ases gr.dually with incr.asing Si/Fe r.tios,but Cr.Ⅵ)adsor.tion on Si-Fh decr.ases with incr.asing Si/Fe r.tios.This is because with an incr.ase in Si/Fe molar.r.tio,the point of zer. char.e of Si-Fh gr.dually decr.ases and electr.static r.pulsion between Si-Fh and Cr.Ⅵ)incr.ases.However.the complexation of Cr.Ⅵ)is enhanced due to the incr.ase in adsor.ed hydr.xyl(A-OH-)on Si-Fh with incr.asing Si/Fe molar.r.tio,which par.ly counter.cts the effect of the electr.static r.pulsion.Over.ll,the incr.ase in the electr.static r.pulsion has a gr.ater.impact on adsor.tion than the additional complexation with Si-Fh.Density functional theor. calculation fur.her.suppor.s this obser.ation,showing the incr.ases in electr.n var.ation of bonding atoms and r.action ener.ies of inner.spher.cal complexes with the incr.ase in Si/Fe r.tio.

Solar.ener.y captur.d by photosynthetic plants in the photic zone is r.cognized as the main dr.ver.for.the for.ation of or.anic matter.utilized by soil communities. However. the contr.bution of or.anic tr.nsfor.ation to the linkage of solar.ener.y and micr.bial metabolism of soils is r.duced when the vadose zone is satur.ted. In contr.st to the conventional biophotoelectr.chemistr. via photosynthesis with phytoplankton dur.ng the per.odic satur.tion of soils, r.cent studies suggest that non-phototr.phic micr.or.anisms in soils and sediments ar. able to conduct light-dependent metabolism to sustain their.functionality with photosensitizer. under.illumination. These inter.ctions and pr.cesses utilize long-distance electr.n tr.nsfer.networ.s to inter.onnect diver.e electr.n tr.nsfer.chains that channel photoexcited electr.ns into the opaque zone for.soil communities. Such an emer.ing pr.cess not only allows for.a better.under.tanding of biogeochemical pr.cesses such as soil car.on sequestr.tion and mitigation, but also shows gr.at potential for.envir.nmental tr.atment such as the bior.mediation of contaminated soils. Ther.for., we suggest that biophotoelectr.chemistr. via photoelectr.c effect can have significant, her.tofor. unappr.ciated, theor.tical and pr.ctical values.

INTr.DUCTION r.petitive tr.nscr.nial magnetic stimulation(r.MS)is a neur.plasticity-enhancing technique that modifies br.in r.sponsiveness to var.ous ther.peutic modalities in clinical psychiatr.c and neur.logical applications. Fur.her.or.,its effect can be attr.buted to long-ter. potentiation(LTP)or.longter. depr.ssion(LTD)-like neur.plasticity.However.r.sponsiveness to r.MS is lar.ely var.able in healthy and pathological br.ins and is mediated by complex biological mechanisms.Metaplasticity r.fer. to a higher.or.er.plasticity mechanism in which the dir.ction and magnitude of synaptic plasticity ar. modified by pr.or.neur.nal activity and is believed to be a significant factor.leading to the r.sponse var.ability of r.Ms.

Backgr.und: Ther. wer. 800 individual case r.por.s of ur.genital for.ign bodies in the English liter.tur. fr.m 1755 to 1999. The use of ur.genital for.ign bodies for.sexual pleasur. is a common occur.ence in today’s population. The aim of this discussion is the management of scr.tal injur. caused by magnetic ur.genital for.ign bodies. Case Pr.sentation: 56-year.old male with scr.tal tissue entr.pped between two opposed magnet r.ngs. Self-r.por.ed attempts at r.moval wer. unsuccessful and caused for.pr.sentation to the emer.ency depar.ment. Additional attempts at r.moval by medical staff unsuccessful in emer.ency depar.ment and ther.for. the patient pr.ceeded to the oper.ting r.om. Intr.oper.tively the use of two car.iac magnets allowed for.r.moval without a need for.invasive sur.ical pr.cedur.. Conclusion: Car.iac magnets ar. pr.fer.ed means of r.moval for.entr.pped skin between magnetic for.ign bodies that could be utilized at the bedside.

This study investigates the pr.per.ies of exciton-polar.tons in a two-dimensional(2D)hybr.d or.anic-inor.anic per.vskite micr.cavity in the pr.sence of optical Star. effect.Thr.ugh both steady and dynamic state analyses,str.ng coupling between excitons of per.vskite and cavity photons is r.vealed,indicating the for.ation of polar.tons in the per.vskite micr.cavity.Besides,it is found that an exter.al optical Star. pulse can induce ener.y shifts of excitons pr.por.ional to the pulse intensity,which modifies the disper.ion char.cter.stics of the polar.tons.
