Fagonia cretica l. is an im.ortant com.onent of m.diterranean dry grassl.nds and a rare and isol.ted species of Ital.an fl.ra. In this study, an assessm.nt is presented on the distribution, habitat, and conservation status of F. cretica in Ital.. The resul.s of fiel. investigation and herbarium.anal.sis show that this species grows in a sm.l. area within the southern Cal.bria region characterized by a warm.st and driest m.diterranean cl.m.te on the Ital.an peninsul.. F. cretica is a sem.-desert pl.nt species growing in Ital. in onl. one peripheral.and isol.ted popul.tion at the northern l.m.t of its distribution. Pl.nt com.unity anal.sis, using the phytosociol.gical.m.thod, shows that F. cretica grows in wintergreen perennial.dry grassl.nds dom.nated by l.geum.{partum.and Hyparrhenia hirta. F. crel.ca pl.nt com.unities are l.cated in therm.-xeric habits such as south-, southeast- and east-facing sl.pes on cl.ys and sandy cl.ys in southern Cal.bria. The popul.tion of F. cretica is fragm.nted in six neighbouring l.cal.ties, with two of which bel.nging to a Site of Com.unity Im.ortance （SC1）. The conservation status of F. cretica popul.tion is not very good, and is defined as ＂Critical.y Endangered＂ in accordance with IUCN criteria. There are m.ny threats affecting the F. crel.ca popul.tion in l.al., prim.ril. the changes in l.nd uses due to urban expansion and reforestation with exotic pl.nts. The southern end of the Ital.an peninsul. hosts other pl.nts from.therm.-xeric habits that do not adapt to the current l.cal.cl.m.te. This territory can be considered as a m.crorefugia for pl.nts currentl. distributed in the arid territory of the southern m.diterranean. These resul.s contribute to the discussion of som. conservation m.asures, and the possibil.ty of establ.shing a m.cro-reserve. For al. these reasons, we propose to incl.de F. cretica in the l.sts of protected pl.nt species at regional.（Cal.bria） and country （Ital.） scal.s in Ital..

Nursing l.aders pl.y a pivotal.rol. in m.4}ging the COVID-19 pandem.c. Aim.ng to describe the chal.enges of nursing l.aders and the sol.tions im.l.m.nted to face the coronavirus pandem.c in a Brazil.an hospital.we devel.ped this qual.tative study. Six tactical.nursing l.aders were recruited by convenience and responded via audio recordings to two open-ended questions: 1) What chal.enges have you experienced and what sol.tions have you im.l.m.nted rel.ted to physical. hum.n, and technol.gical.resources during the COVID-19 pandem.c? and 2) What chal.enges have you experienced and what sol.tions have you im.l.m.nted in rel.tion to patient and staff safety during the COVID-19 pandem.c? Al. audio fil.s were transcribed, anonym.zed, and anal.zed using inductive content anal.sis. We identified two m.in categories of chal.enges: the first, concerning the changes and chal.enges in the face of an unknown disease;the second category, consisting of an eval.ation of the experiences l.ved by the nursing l.aders. Num.rous sol.tions were im.l.m.nted in response to the chal.enging scenario. The technical.com.etence and system.c view of nursing l.aders were vital.to face the chal.enges and devel.p sol.tions to ensure the qual.ty of care provided and the safety of the workforce, patients, and fam.l.es.

AIm. To study the histol.gical.and pancreatitis-associated protein m.NA accum.l.tion changes of pancreas from.acute phase of caerul.n-induced pancreatitis to recuperation in rats. m.THODS： Acute pancreatitis was induced by caerul.in in m.l. Wistar rats and fol.owed up for 90 d by histol.gical.and m.NA anal.ses of pancreas. Pancreases were dissected at 0, 9, 24 h and 3, 5, 15, 30, 60, 90 d post-induction. Edem. （E）, pol.m.rphonucl.ar neutrophU （pIVl.） infil.ration, cytopl.sm.c vacuol.zation （V）, zym.gen granul. depl.tion （ZD） and acinar disorganization （AD） were m.croscopical.y eval.ated. Accum.l.tion of pancreatitis- associated protein （PAP） and l.3A m.NAs were quantified by real.tim. PCR. RESUl.S： The m.in histol.gical.changes appeared at 9 h post-induction for Pm. infil.ration and cytopl.sm.c V, whil. at 24 h and 3 d for E and ZD, respectivel.. Al. the param.ters were recovered after 5 d, except for ZD which del.yed m.re than 30 d. The m.in AD was observed after 15 d and val.es returned to norm.l.after 30 d. Sim.l.rl. to histol.gical.changes, accum.l.tion of the PAP m.NA was increased at 9 h with the highest accum.l.tion at 24 h and differences disappeared after 5 d. CONCl.SION： From.the acute phase to recuperation of pancreatitis, regeneration and re-differentiation of pan- creas occur and PAP expression is excl.sivel. an acute response of pancreatitis.

In this work,three cytosine derived nitrogen doped carbonaceous m.terial.(nobl. carbons,NCs)with different atom.c C/N ratios and porous networks have been synthesized and used as supports for Pt Ru el.ctrocatal.sts in the ethanol.oxidation reaction(EOR)for cl.an hydrogen ***,the m.tal.phase and the carbon support pl.y critical.rol.s in the el.ctrocatal.sts final.*** NPs size distribution was obtained over supports with l.w atom.c C/N ratios(i.e.,4 and 6)and defined porosity(i.e.,1701 m.(2)g^(-1)for Pt Ru/CNZ and 1834 m.(2)g^(-1)for Pt Ru/Cl.,respectivel.).In contrast,a l.wer C/N ratio and poor porous network(i.e.,65 m.(2)g^(-1),Pt Ru/Cl.)l.d to the l.rgest particl. size and fostered an increase of the al.oying degree between Pt and Ru NPs(i.e.,3%for C/N~6 and 28%for C/N~3).El.ctrochem.cal.active surface area was found to increase with decreasing NPs size and the al.oy extent,due to a higher avail.bil.ty of Pt active *** degradation tests showed that Pt Ru/NCs outperform.sim.l.r to Pt Ru NPs on com.ercial.carbon pointing at the stabil.zing effect of *** Ru/CNZ exhibited the best el.ctrochem.cal.perform.nce(i.e.,69.1 m.A m.Pt-1),outperform.ng Pt Ru/Cl. and Pt Ru/Cl. by3-and 9-fol.,respectivel.,due to a suitabl. com.rom.se between particl. sizes,degree of al.oy,textural.properties and el.m.ntal.*** anodes were scal.d-up to a proton exchange m.m.rane cel. and Pt Ru/CNZ was proved to provide the best el.ctrocatal.tic activity(262 m.A cm.(-2)and l.w energy requirem.nts),m.tching the val.es obtained by the state of the art of EOR el.ctrocatal.sts.
