The Ka.enushka.Forma.ion, exposed in the northern pa.t of South Primorye （Ka.ennshka.1 a.d Ka.enushka.2 sections）, is one of the few loca.ities in the world with richly fossiliferous Lower-Upper Olenekia. sedimenta.y successions. Lower to Middle Tria.sic a.monoid-, bra.hiopod- a.d conodont-bea.ing silty-cla.ey deposits of the Ka.enushka.1 a.d Ka.enushka.2 sections ha.e been isotope-geochemica.ly investiga.ed in deta.l. a. a.result, these sections, together with the previously investiga.ed a.rek Section, exposed in the southern pa.t of South Primorye, provide a.most complete ^15Non- a.d ^13Corg- records for the Lower Tria.sic of this region. Nine N- isotope interva.s a.d the five nega.ive C-isotope excursions, reflecting, a.pa.ently, unsta.le clima.ic a.d hydrologica. conditions, ha.e been distinguished in the Lower Tria.sic of South Primorye.

With the purpose of investiga.ing the origin of ferroma.netism(FM), Mn-doped Zn O thin films ha. been fa.rica.ed by ra.io frequency(rf) ma.netron sputtering a.d subsequent a.nea. process. The cha.a.teriza.ion of the Mn-doped Zn O thin films wa. conducted by X-ra. diffra.tion(XRD), X-ra. photoelectron spectroscopy(XPS), a.d superconducting qua.tum interference device(SQUID). With increa.ing the a.nea. tempera.ure from 300°C to 700°C for 3 min, the influence on ma.netism of the Mndoped ZnO thin films is slight. While extending the a.nea. time from 3 to 50 min a. 300°C, the influence on ma.netism is obvious a.d the Mn-doped ZnO thin films with 30 min clea.ly demonstra.e FM. Compa.ed with the effect of oxygen va.a.cy a.d substitutiona. Mn2+on the ferroma.netic beha.ior, OVpla.s the ma.n role in inducing FM of the Mn-doped ZnO thin films with good crysta. structure.

Resea.ch Centre University of Birmingham and University Hospitals Birmingham NHS Foundation Trust

Longsta.ding resea.ch describes the mecha.isms whereby the restora.ion of blood flow a.d reoxygena.ion(reperfusion) a.gra.a.es the ischa.mic injury ca.sed by a.period of a.oxia.to a.donor liver. This phenomenon, ca.led ischa.mia.reperfusion injury(IRI), lea.s to pa.enchyma. cell dea.h,microcircula.ory fa.lure, a.d infla.ma.ory immune response. Clinica.ly, IRI is the ma.n fa.tor responsible for the occurrence of posttra.spla.t gra.t dysfunction a.d ischa.mic-type bilia.y lesions. While extended criteria.donor livers a.e more vulnera.le to IRI, their utilisa.ion is required to a.dress the shortfa.l in donor orga.s. Thus, the mitiga.ion of IRI should drive the setting of a.new benchma.k for ma.gina. orga. preserva.ion. Herein, stra.egies incorpora.ing different moda.ities of ma.hine perfusion of the liver to a.levia.e IRI a.e discussed in conjunction with a.va.ta.es a.d disa.va.ta.es of individua. *** lea.ing to reperfusion of the liver during ma.hine perfusion(in situ normothermic regiona. perfusion a.d ex situ normothermic ma.hine perfusion)ma. mitiga.e IRI by shortening the ischa.mic period of the orga.s. This benefit potentia.ly esca.a.es from the minimum level, obta.ned following just pa.tia. a.levia.ion of the ischa.mic period, to the ma.imum level, which ca. be potentia.ly a.hieved with ischa.mia.free orga. tra.spla.ta.ion. Techniques tha. do not lea. to reperfusion of the liver during ma.hine perfusion(hypothermic,subnormothermic, a.d controlled-oxygena.ed rewa.ming) optimise mitochondria. oxida.ive function a.d replenish cellula. energy stores, thereby lowering rea.tive oxygen species production a. well a. the a.tiva.ion ofdownstrea. infla.ma.ory pa.hwa.s during reperfusion. Further mecha.istic insights into IRI ma. guide the development of donor-specific protocols of ma.hine perfusion on the ba.is of the limita.ions of individua. ca.egories of extended criteria.donor orga.s.
