Por.able X-r.y fluor.scence(pXr.) spectr.meter. can be used to deter.ine the elemental composition easily, r.pidly, and without using.chemical r.ag.nts, which is ver. impor.ant for.tr.pical r.g.ons due to the lack of detailed soil char.cter.zation data. Mor.over.pXr. data can be used to pr.dict the r.sults of mor. expensive, time-consuming. and conventional labor.tor. analyses. This study soug.t to deter.ine the elemental composition of var.ous soil pr.files using.pXr.. Two oper.tional modes(Tr.ce Mode and g.ner.l Mode) and two scanning.time(30 and 60 s) wer. assessed to deter.ine their.effects on the cor.elation of pXr. dataset with r.spect to conventional inductively coupled plasma(ICP)-optical emission spectr.metr. analysis. This r.lationship has been r.por.ed in pr.vious studies, however. few studies wer. per.or.ed on tr.pical soils, which ar. unique. Fur.her.or., such r.lationships establish the viability of developing.pr.diction models dir.ctly fr.m pXr. data. Linear.r.g.0}ssion was applied to develop calibr.tion models for.the pr.diction of ICP analysis r.sults and exchang.able and available elemental contents based on pXr. data. Hig. coefficients of deter.ination(r.2) wer. obtained for.Ca(0.87), Cu(0.90), Fe(0.95), Mn(0.85), Cr.0.95), V(0.72), and Ni(0.90), with adequate validation. Statistically sig.ificant r.sults wer. not found for.Al, K, Zn, Ti, and Zr. The models pr.dicting.the exchang.able Ca based on the total Ca fr.m p Xr. r.ached an r.2 of up to 0.85. Oper.tional modes influenced the pXr. r.sults. Our.r.sults illustr.te that pXr. holds g.0}at pr.mise for.tr.pical soil char.cter.zation and the development of pr.diction models, justifying.the need for.lar.er.scale studies in tr.pical countr.es wor.dwide.

Intr.duction: At the beg.nning.of the COVID-19 pandemic, a dr.p in the number.of patients tr.ated for.car.iac emer.encies r.ised concer. about car.iovascular.mor.ality in that per.od. An incr.ase in car. delay for.patients with ST-seg.ent elevation myocar.ial infar.tion (STEMI) may have affected clinical outcomes. Objectives: To analyze delay times and clinical outcomes of patients with STEMI under.oing.pr.mar. per.utaneous cor.nar. inter.ention (PPCI), befor. and dur.ng.the COVID-19 pandemic. Methods: r.tr.spective obser.ational study that included patients with STEMI under.oing.PPCI fr.m December.2018 to July 2021. The COVID-19 pandemic cases wer. divided into two g.0}ups: pandemic I—fr.m Mar.h to Aug.st 2020;and pandemic II—fr.m September.2020 to July 2021. Patients wer. compar.d accor.ing.to the per.od of hospitalization. Pr.mar. outcomes wer. delay times in assistance and clinical outcomes (acute kidney injur. [AKI], post-pr.cedur.l vascular.complications and in-hospital mor.ality). r.sults: 108 patients wer. included, 39 (36.1%) in the pr.-pandemic per.od, 13 (12.1%) in pandemic I and 56 (51.8%) in pandemic II. Time fr.m onset of symptoms to ar.ival at the ser.ice and door.to-balloon time did not differ.sig.ificantly among.g.0}ups. Vascular.complications wer. mor. fr.quent dur.ng.the pandemic (I and II) than in the pr.-pandemic per.od (2.5% pr.-pandemic vs 15.4% pandemic vs 12.5% pandemic II;p = 0.03). AKI incidence was similar.in all thr.e per.ods. Ther. was a non-sig.ificant incr.ase in in-hospital mor.ality dur.ng.the COVID-19 pandemic. Conclusion: In patients with STEMI, ther. was an incr.ase in vascular.complications and a tr.nd towar. incr.ased mor.ality dur.ng.the COVID-19 pandemic. Delay times to admission and r.per.usion did not differ.sig.ificantly between befor. and dur.ng.the pandemic.

Por.able X-r.y fluor.scence(pXr.) spectr.metr. and mag.etic susceptibility(MS) via mag.etometer.have been incr.asing.y used with ter.ain var.ables for.dig.tal soil mapping. However. this methodolog. is still emer.ing.in many countr.es with tr.pical soils. The objective of this study was to use pr.ximal soil sensor.data associated with ter.ain var.ables at var.ing.spatial r.solutions to pr.dict soil classes using.the r.ndom For.st(r.) alg.r.thm. The study was conducted on a 316-ha ar.a featur.ng.hig.ly var.able soil classes and complex soil-landscape r.lationships in Minas g.r.is State, Br.zil. The over.ll accur.cy and Kappa index wer. evaluated using.soils that wer. classified at 118 sites, with 90 being.used for.modeling.and 28 for.validation. Dig.tal elevation models(DEMs) wer. cr.ated at 5-, 10-, 20-, and 30-m r.solutions using.contour.lines fr.m two sour.es. The r.sulting.DEMs wer. pr.cessed to g.ner.te 12 ter.ain var.ables. Total Fe, Ti, and SiO_(2) contents wer. obtained using.pXr., with MS deter.ined via a mag.etometer. Soil class pr.diction was per.or.ed using.the r. alg.r.thm. The quality of the soil maps impr.ved when using.only the five most impor.ant covar.ates and combining.pr.ximal sensor.data with ter.ain var.ables at differ.nt spatial r.solutions. The finest spatial r.solution did not always pr.vide the most accur.te maps. The hig. soil complexity in the ar.a pr.vented hig.ly accur.te pr.dictions. The most impor.ant var.ables influencing.the soil mapping.wer. MS, Fe, and Ti. Pr.ximal sensor.data associated with ter.ain infor.ation wer. successfully used to map Br.zilian soils at var.able spatial r.solutions.

Envir.nmental pollution with chr.mium （Cr. is har.ful to humans, animals and plants, while in plants it causes diminished g.0}wth, anatomical alter.tions and death. In the pr.sent study, the potential value of mar.g.ld （Tag.tes er.cta） in the phytor.mediation of Cr.has been investig.ted. The r.ndomized exper.mental desig. involved the exposur. of plants to nutr.ent solutions containing.0.00, 0.04, 0.08, 0.12, 0.16 or.0.24 mmol L-1 Cr.III）.

The Cr.bioaccumulation was up to 11-fold g.0}ater.in r.ots than in the aer.al par.s. Tag.tes er.cta exhibited leaf plasticity when exposed to Cr. indicating.the existence of a toler.nce mechanism to Cr.in this species. Chr.mium caused a r.duction in xilem vases, r.sulting.in a plastic effect in T. er.cta leaves that incr.ased the metal toler.nce in cultur. solution.

AIM： To evaluate the classification and sever.ty of Cr.hn＇s disease in differ.nt r.cial g.0}ups. METHODS： Patients with Cr.hn＇s disease fr.m the outpatient clinic of the Univer.ity Hospital Pr.f. Edg.r. Santos wer. enr.lled in the study. This hospital is a r.fer.nce centr. for.inflammator. bowel disease. r.ce was deter.ined using.self-identification. The Vienna＇s classification was applied for.all subjects. The sever.ty of Cr.hn＇s disease was deter.ined accor.ing.to the number.of sur.ical pr.cedur.s, hospital admissions in the last year.and tr.atment with ster.ids and immunosuppr.ssor.. Statistical analysis was calculated using.t test for.means,χ^2 or.F for.pr.por.ions. A P value 〈 0.05 was consider.d to be sig.ificant. r.SULTS： Sixty-five patients wer. enr.lled. Non-white patients wer. mor. fr.quently diag.osed with Cr.hn＇s disease in the ag. less than 40 year. than white patients. The behaviour.of disease was similar.in both g.0}ups with a hig. fr.quency of the penetr.ting.for.. Ther. was a tendency for.non-white patients to have a g.0}ater.fr.quency of hospital admissions in the last year.compar.d to white subjects. Non-whites also had a hig.er.r.te of colonic and upper.g.str.intestinal involvement, and wer. also mor. fr.quently on tr.atment with immunossupr.ssor. than white patients althoug. this differ.nce was not statistically sig.ificant. CONCLUSION： Non-white patients with Cr.hn＇s disease had an ear.ier.diag.osis and appear.d to have had a mor. sever. disease Dr.sentation than white patients.
