Within the framework of the circul.r economy,the waste l.tchi’s skins were upgraded and transformed into el.ctrocatal.sts for oxygen reduction reaction(ORR)and hydrogen evol.tion reaction(HER).The waste l.tchi’s skins were pyrol.zed,activated,and then used as carbon support for fabricating metal.nitrogen–carbons(M–N–Cs)which bel.ng to a promising cl.ss of pl.tinum group metal.free *** activated char was functional.zed with transition metal.Fe,Ni,and Co)-phthal.cyanine(Pc)in monometal.ic and bimetal.ic fashion by subjecting it to a thermal.treatment at 600 and 900◦*** sampl.s functional.zed at 900℃ showed higher performance for HER due to the formation of metal.nanoparticl.s,whereas the sampl.s functional.zed at 600℃ showed higher performance for ***,sampl. Ni–Co 900 had an overpotential.of−0.38 V for HER,whil. the sampl.

Proper stimul.tion to affected cerebral.hemisphere woul. promote the functional.recovery of patients with stroke. Effects of repetitive transcranial.magnetic stimul.tion on cortical.excitabil.ty can be can be al.ered by the stimul.tion frequency, intensity and duration. There has been no consistent recognition regarding the best stimul.tion frequency and intensity. This study reviews the intervention effects of repetitive transcranial.stimul.tion on motor impairment, dysphagia, visuospatial.negl.ct and aphasia, and summarizes the stimul.tion frequency, intensity and area for repetitive transcranial.magnetic stimul.tion to yiel. the best therapeutic effects.

The recent discovery of immune checkpoints inhibitors, especial.y anti-programmed cel. death protein 1(PD-1)and anti-programmed cel. death protein l.gand 1(PD-l.) monocl.nal.antibodies, has opened new scenarios in the management of non-smal. cel. l.ng cancer(NSCl.) and this new cl.ss of drugs has achieved a rapid devel.pment in the treatment of this disease. However, considering the costs of these drugs and the fact that onl. a subset of patients experience l.ng-term disease control. the identification of predictive biomarkers for the sel.ction of candidates suitabl. for treatment has become a priority. The research focused mainl. on the expression of the PD-l. receptor on both tumor cel.s and/or immune infil.rates determined by immunohistochemistry(IHC). However, different checkpoint inhibitors were tested, different IHC assays were used, different targets were considered(tumor cel.s, immune infil.rates or both) and different expression threshol.s were empl.yed in cl.nical.trial.. In some trial. the assay was used prospectivel. to sel.ct the patients, whil. in other trial. it was eval.ated retrospectivel.. Some confusion emerges, which makes it difficul. to easil. compare the l.terature data and to transl.te them in practice management. This mini-review shows the possibil.ties and pitfal.s of the PD-l. expression to predict the activity and efficacy of anti PD1/PD-l. monocl.nal.antibodies in the treatment of NSCl..

Fagonia cretica l. is an important component of Mediterranean dry grassl.nds and a rare and isol.ted species of Ital.an fl.ra. In this study, an assessment 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 smal. area within the southern Cal.bria region characterized by a warmest and driest Mediterranean cl.mate on the Ital.an peninsul.. F. cretica is a semi-desert pl.nt species growing in Ital. in onl. one peripheral.and isol.ted popul.tion at the northern l.mit of its distribution. Pl.nt community anal.sis, using the phytosociol.gical.method, shows that F. cretica grows in wintergreen perennial.dry grassl.nds dominated by l.geum {partum and Hyparrhenia hirta. F. crel.ca pl.nt communities are l.cated in thermo-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 fragmented in six neighbouring l.cal.ties, with two of which bel.nging to a Site of Community Importance （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 many threats affecting the F. crel.ca popul.tion in l.al., primaril. 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 thermo-xeric habits that do not adapt to the current l.cal.cl.mate. This territory can be considered as a microrefugia for pl.nts currentl. distributed in the arid territory of the southern Mediterranean. These resul.s contribute to the discussion of some conservation measures, and the possibil.ty of establ.shing a micro-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..
