In this pape., we.de.ive.the.analytical solutions in a thre.-dime.sional anisotropic magne.oe.e.troe.astic bimate.ial space.subje.t to uniform e.te.de. dislocations and tractions within a horizontal circular are.. By virtue.of the.Stroh formalism and Fourie. transformation, the.final e.pre.sion of solutions in the.physical domain contains only line.inte.rals ove. [0, 2π] rathe. than infinite.inte.rals. As the.re.uce. case., the.half-space.and homoge.e.us full-space.solutions can be.dire.tly de.ive. from the.pre.e.t solutions. Also, in te.ms of mate.ial domains, the.pre.e.t solutions can be.re.uce. to the.pie.oe.e.tric, pie.omagne.ic, pure.y e.astic mate.ials with diffe.e.t symme.rie. of mate.ial prop- e.ty. To carry out nume.ical calculations, Gauss quadrature.is adopte.. In the.nume.ical e.ample., the.e.fe.t of diffe.e.t loading locations on the.re.ponse.at the.inte.face.is analyze.. It is shown that, whe. the.magne.ic traction or e.e.tric dislocation is applie., the.physical quantitie. on the.inte.face.may not de.re.se.monotonically as the.loading are. move. away from the.inte.face. The.distributions of diffe.e.t in-plane.physical quantitie. on the.uppe. and lowe. inte.face. unde. various e.te.de. horizontal loadings are.compare. and the.diffe.e.ce. are.discusse.. The.work pre.e.te. in this pape. can se.ve.as be.chmarks for future.nume.ical studie. in re.ate. re.e.rch fie.ds.

At about 270 K, this compound shows a first orde. phase.transition.

Background: The.accumulation of fre. radicals is linke. to a numbe. of dise.se.. Fre. radicals can be.scave.ge. by antioxidants and re.uce.the.r harmful e.fe.ts. It is the.e.ore.e.se.tial to look for naturally occurring antioxidants that come.from plants, as synthe.ic antioxidants are.toxic, carcinoge.ic and proble.atic for the.e.vironme.t. Lycope.e.is one.of the.carote.oids, a pigme.t that dissolve. in fat and has antioxidant prope.tie.. Mate.ials and Me.hods: The.antioxidant and fre. radical scave.ging activity we.e.asse.se. using the.2,2-diphe.yl-1-picrylhydrazyl (DPPH) assay. The.impact of lycope.e.on bacte.ia (e. coli) susce.tibility to γ-radiation was e.amine. by radio se.sitivity assay. The.study also e.amine. the.induction of strand bre.ks in plasmid pUC19 DNA and how lycope.e.e.tract prote.te. the.DNA from γ-radiation in vitro. Re.ults: At varying conce.trations, lycope.e.de.onstrate. its ability to scave.ge.fre. radicals such as 2, 2-diphe.yl-1-picrylhydrazyl (DPPH). IC50 for lycope.e.was de.e.mine. at 112 μg/mL which was almost partial to IC50 of standard antioxidant L-ascorbic acid. The.D10 value.180 Gy of e. coli was found to be.>2-fold highe. in the.e.tract-containing lycope.e.sample.than in the.e.tract-fre. controls. The.lycope.e.e.tracts inhibite. the.radiation-induce. de.e.ioration of the.plasmid pUC19 DNA. At an IC50 conce.tration, lycope.e.provide. the.highe.t le.e. of prote.tion. Conclusion: Lycope.e.functions as an e.ficie.t fre. radical scave.ge. and possible.natural antioxidant source. For cance. patie.ts and othe.s who fre.ue.tly e.pose.the.se.ve. to radiation, lycope.e.may be.a use.ul plant-base. pharmace.tical product for tre.ting a varie.y of dise.se. cause. by fre. radicals.

Background: Kidne. transplantation is the.be.t tre.tme.t for e.d-stage.chronic kidne. dise.se. Howe.e., its re.lization is confronte. by se.e.al difficultie. among which are.anatomical variations. Obje.tive. The.obje.tive.of our work was to de.cribe.the.impact of re.al pe.icle.variations on the.ope.ative.proce.ure.as we.l as the.complications. Me.hod: We.conducte. a re.rospe.tive.study on living kidne. donors and the.r re.ipie.ts in the.pe.iod from 2012 to 2017. Se.e.al variable. we.e.studie., in particular socio-de.ographic, ope.ative.and progre.sion. Re.ults: We.ide.tifie. 49 living donors whose.me.n age.was 37.59 ye.rs with a male.to-fe.ale.ratio of 3.9 and 45 ± 10.75 ye.rs in the.re.ipie.ts. The.pre.ale.ce.of re.al vascular abnormalitie. was highe. with a proportion of 46.94% in re.ipie.ts. The.le.t kidne. was most fre.ue.tly re.ove. (75.51%) and the. ke.t mainly in HTK (95.92%). The.e.vascular anomalie. we.e.associate. with a longe. ope.ating time.but this diffe.e.ce.was not statistically significant (p = 0.5804). The. had no e.fe.t on hot and cold ische.ia time. (p = 0.9838, p = 0.8389). Complications we.e.obse.ve. in 11 patie.ts, all re.ipie.ts, i.e. 11.22%, and we.e.not re.ate. to the.pre.e.ce.of vascular abnormalitie. (p = 0.086). We.obse.ve. that 4.08% of de.ths we.e.all re.ipie.ts. Conclusion: It se.ms that kidne. transplantation with multiple.re.al arte.ie. and/or ve.ns doe. not significantly le.gthe. the.ope.ating time.and doe. not promote.the.onse. of complications.
