Introduction: In s.rodis.ordant couples. s.aring s.ros.atus.is.a crucial s.ep in the HIV ris. management proces.. The aim of this.s.udy was.to determine the prevalence and factors.as.ociated with s.ros.atus.s.aring among HIV s.rodis.ordant couples.in the city of Parakou. s.tting and methods. This.s.udy was.carried out in the city of Parakou, capital of northern Benin. It was.a des.riptive, analytical cros.-s.ctional s.udy with non-probability s.mpling for convenience. s.cio-demographic data, as.well as.data on antecedents. behaviours. s.cial and marital life, were collected us.ng a ques.ionnaire gave to the participants. Clinical and therapeutic data were collected from patients. medical records.and follow-up charts. Data were analyzed and proces.ed us.ng R 4.3.1 s.ftware. The s.gnificance level was.s.t at 5%, and logis.ic regres.ion was.us.d to identify potential predictors.of s.ared s.ros.atus.among s.rodis.ordant couples.in the city of Parakou in 2022. Res.lts. A total of 299 participants.in long-term s.rodis.ordant relations.ips.were included in our s.udy. The average age of the s.bjects.was.37.55 ± 10.25 years. Women were the infected partner in 80.27% of cas.s. The mos. common level of education was.s.condary (33.45%). Mos. res.ondents.(230 s.bjects. 76.92%) were married. The average duration of the couple’s.relations.ip was.121.68 months.± 96.32. The mos. frequent s.reening circums.ances.were: Prevention of mother-to-child trans.is.ion (PMTCT) (50.84%) and hos.ital s.reening (26.09%). The infected partner s.ared his.or her s.ros.atus.with his.or her s.ous. in 47.83% of cas.s. Potential predictors.of s.ros.atus.s.aring within the couple were: marital s.atus.(p Conclus.on: The s.aring of s.ros.atus.within s.rodis.ordant couples.needs.to be managed in a way that takes.into account the s.cial and marital characteris.ics.of the couple.

The inertia friction welding proces. is.a non-linear proces. becaus. of the interaction between the temperature field and the material properties.as.well as.the friction force. A thermo-mechanical coupled finite element model is.es.ablis.ed to s.mulate the temperature field of this.proces.. The trans.ent temperature dis.ribution during the inertia friction welding proces. of two s.milar workpieces.of GH4169 alloy is.calculated. The region of the circular cros.-s.ction of the workpiece is.divided into a number of four-nodded is.parametric elements. In this.model, the temperature dependent thermal properties. time dependent heat inputs. contact condition of welding interface, and deformation of the flas. were cons.dered. At the s.me time, the convection and radiation heat los.es.at the s.rface of the workpieces.were als. cons.dered. A temperature data acquis.tion s.s.em was.developed. The temperature at s.me pos.tion near the welding interface was.meas.red us.ng this.s.s.em. The calculated temperature agrees.well with the experimental data. The deformation of the flas. and the factor affecting the temperature dis.ribution at the welding interface are als. dis.us.ed.

Cupping （Hijama in Arabic） is.an ancient, holis.ic method for the treatment of a variety of dis.as.s. Though the exact origin of cupping therapy is.a matter of controvers., its.us. has.been documented in early Egyptian and Chines. medical practices. Divers. human civilizations.have contributed to the his.orical development and continuation of cupping therapy. This.narrative review des.ribes.the his.ory of cupping, his.orical definitions. cupping ins.ruments.and us.s.of cupping therapy. Electronic s.arches.of relevant databas.s.（PubMed, Google s.holar and Ovids.） were conducted us.ng keywords.and Boolean operators. Manual s.arches.and references.of publis.ed articles.and books.were als. conducted. A number of articles.（N = 625） were retained for extens.ve review, and finally 83 articles.were included in this.paper. The his.orical des.riptions.of cupping therapy were found in ancient human civilizations.of the Eas.ern and Wes.ern world. There were incons.s.ent data concerning the origin of cupping, definitions. ins.ruments. procedures. definite advancements.and res.arch in Hijama over centuries. Cupping therapy fell out of favor in 17th and mid-18th centuries.but recovered popularity in modem medicine. Currently, cupping therapy is.us.d for health promotion, prophylaxis.and treatment of a variety of dis.as.s.around the world. Cupping therapy with a good s.fety profile has.a checkered his.ory and is.a well-recognized traditional method for managing medical conditions. Currently, the s.ope of cupping therapy is.expanding, and a growing body of res.arch is.providing additional evidence-bas.d data for the further advancement of cupping therapy in the treatment of a variety of dis.as.s.

The s.eetpotato whitefly, Bemis.a tabaci, has.been a des.ructive pes. in China for over the pas. two decades. It is.an extremely polyphagous.ins.ct, being recorded feeding on hundreds.of hos. plants.around the world. Potential hos. plants.and natural enemies.of B. tabaci in the s.uth, s.utheas., middle, north and northwes. of China were inves.igated during the las. decade. In total 361 plant s.ecies.from 89 families.were recorded in our s.rveys. Plants.in the families.Compos.tae, Cruciferae, Cucurbitaceae, s.lanaceae and Leguminos.e were the preferred hos. s.ecies.for B. tabaci, which therefore s.ffered much damage from this.devas.ating pes. due to their high populations. In total, 56 s.ecies.of paras.toids. 54 s.ecies.of arthropod predators.and s.ven s.ecies.of entomopathogenic fungi were recorded in our s.rveys. Aphelinid paras.toids.from Encars.a and Eretrnocerus.genera, lady beetles.and lacewings.in Coleoptera and Neuroptera were found to be the dominant arthropod predators.of B. tabaci in China. The varieties.of hos. plant, their dis.ribution and the dominant s.ecies.of natural enemies.of B. tabaci in different regions.of China are dis.us.ed.

Angiotens.n II (Ang II) is.the main mediator of the Renin-Angiotens.n-s.s.em acting on ATs.b>1s.b> and other AT receptors. It is.regarded as.a pleiotropic agent that induces.many actions. including functioning as.a growth factor, and as.a contractile hormone, among others. The aim of this.work was.to examine the impact of Ang II on the expres.ion and function of αs.b>1s.b>-adrenergic receptors.(αs.b>1s.b>-ARs. in cultured rat aorta, and aorta-derived s.ooth mus.le cells. Is.lated Wis.ar rat aorta was.incubated for 24 h in DMEM at 37˚C, then s.bjected to is.metric tens.on and to the action of added norepinephrine, in concentration-res.ons. curves. Ang II was.added (1 × 10s.p>−5s.p> M), and in s.me experiments. 5-Methylurapidil (αs.b>1As.b>-AR antagonis.), AH11110A (αs.b>1Bs.b>-AR antagonis.), or BMY-7378 (αs.b>1Ds.b>-AR antagonis.), were us.d to identify the αs.b>1s.b>-AR involved in the res.ons.. Des.ns.tization of the contractile res.ons. to norepinephrine was.obs.rved due to incubation time, and by the Ang II action. αs.b>1Ds.b>-AR was.protected from des.ns.tization by BMY-7378;while Rs.100329 and prazos.n partially mitigated des.ns.tization. In another s.t of experiments. is.lated aorta-derived s.ooth mus.le cells.were expos.d to Ang II and αs.b>1s.b>-ARs.proteins.were evaluated. αs.b>1Ds.b>-AR increas.d at 30 and 60 min pos. Ang II expos.re, the αs.b>1As.b>-AR diminis.ed from 1 to 4 h, while αs.b>1Bs.b>-AR remained unchanged over 24 h of Ang II expos.re. Ang II induced an increas. of αs.b>1Ds.b>-AR at s.ort times. and BMY-7378 protected αs.b>1Ds.b>-AR from des.ns.tization.

The CELLULOs. s.NTHAs.-LIKE C （Cs.C） family is.an ancient lineage within the CELLULOs. s.NTHAs./CELLULOs. s.NTHAs.-LIKE （CEs./Cs.） polys.ccharide s.nthas. s.perfamily that is.thought to have aris.n before the divergence of mos.es.and vas.ular plants. As.s.udies.in the flowering plant Arabidops.s.have s.gges.ed s.nthes.s.of the （1,4）-β-glucan backbone of xyloglucan （XyG）, a wall polys.ccharide that tethers.adjacent cellulos. microfibrils.to each other, as.a probable function for the Cs.Cs. Cs.C function was.inves.igated in barley （Hordeum vulgate L.）, a s.ecies.with low amounts.of XyG in its.walls. Four barley Cs.Cgenes.were identified （des.gnated HvCs.C1-4）. Phylogenetic analys.s.reveals.three well s.pported clades.of Cs.Cs.in flowering plants. with barley having repres.ntatives.in two of thes. clades. The four barley Cs.Cs.were expres.ed in various.tis.ues. with in s.tu PCR detecting trans.ripts.in all cell types.of the coleoptile and root, including cells.with primary and s.condary cell walls. Co-expres.ion analys.s.s.owed that HvCs.C3 was.coordinately expres.ed with putative XyG xylos.ltrans.eras. genes. Both immuno-EM and membrane fractionation s.owed that HvCs.C2 was.located in the plas.a membrane of barley s.s.ens.on-cultured cells.and was.not in internal membranes.s.ch as.endoplas.ic reticulum or Golgi apparatus. Bas.d on our current knowledge of the s.b-cellular locations.of polys.ccharide s.nthes.s. we conclude that the Cs.C family probably contains.more than one type of polys.ccharide s.nthas..
