Changes i. gene exp.essi.n of aquap.ri.s(AQp.-2,-3,-4,-7, ATp.A1,ATp.B1, SGK1, CLi.1(ki.ney and rumen), UT-A1(ki.ney only) and UT-B(rumen only), were assayed vi. real-ti.e q p.R; 18S r RNA was used as an endogenous control. One-way ANOVA followed by Tukey's p.st hoc analysi. was conducted. When ani.als were from Mp. forage-fi.i.hi.g i.creased the relati.e abundance of AQp.(p.≤ 0.05), AQp.(p.≤ 0.05), ATp.B1(p.≤ 0.05), and SGK1(p.≤ 0.05) i. the ki.ney when comp.red to grai.-fed ani.als. i. the rumen, for the Mp.group. AQp. was di.ferenti.lly exp.essed i. both treatments at the fi.i.hi.g p.ase(p.≤ 0.01), wi.h forage-fi.i.hed steers havi.g the hi.hest exp.essi.n of AQp.. For the Mp.group. UT-B had a tendency of p.esenti.g a hi.her exp.essi.n on grai.fed ani.als(p.= 0.075). Overall, these results suggest that p.evi.us p.ane can i.p.ct exp.essi.n of genes associ.ted wi.h water and urea metaboli.m duri.g the fi.i.hi.g p.ase, namely AQp., AQp., ATp.B1, and SGK1 i. the ki.ney, and AQp. and UT-B i. the rumen. The greatest i.p.ct observed on gene exp.essi.n changes of i.vesti.ated genes at the fi.i.hi.g p.ase was reflecti.e of ani.als backgrounded on the moderate p.evi.us p.ane.

Coral-li.e structures of the Y_(3-x)p._(x)Fe_(5-y)Yb_(y)O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y ≤ 0.02) comp.und were synthesi.ed usi.g the sol-gel method. Structural i.vesti.ati.n certi.i.d the Yi. cubi. crystal structure formati.n, wi.hout any secondary p.ase. i. i. shown that, the relati.ely large i.ni. radi.s of the dop.nt cati.ns results i. an exp.nsi.n of the latti.e p.rameter, vari.ti.ns i. the i.na-O-i.ndangle, i.na-O,i.nd-O and i.nc-O bond di.tances and decrease i. the average crystalli.e si.e. Fouri.r transform i.frared(FTi.) and Raman measurements are essenti.l to testi.y the si.gle-p.ase formati.n of Yi. crystal structure and are observed changes i. the stretchi.g and vi.rati.nal modes, resp.cti.ely. The morp.ologi.al study, energy di.p.rsi.e sp.ctroscop.(EDS) sp.ctra and textural p.op.rti.s show coralli.e structures, p.aks associ.ted wi.h p.^(3+) and Yb^(3+) atoms and the effect of dop.nts on surface area,di.meter, and p.re volume, resp.cti.ely. The op.i.al analysi. from di.fuse reflectance sp.ctra wi.nessed an i.crease i. the op.i.al gap.band, a decrease i. Urbach energy and blue shi.t i. the charge transfer,correlated wi.h the exp.nsi.n of the uni. cell due to the dop.nt's i.serti.n i. the Yi. structure. A typ.cal ferri.agneti. behavi.r i. exhi.i.ed by the Y_(3-x)p._(x)Fe_(5-y)Yb_(y)O_(12)comp.und. The saturati.n magneti.ati.n(M_(s)), cubi. ani.otrop. constant(K_(1)) and coerci.e fi.ld(H_(c)) i.crease wi.h the p.^(3+)cati.ns content, as consequence of thei. magneti. nature and di.tri.uti.n around of Fe^(3+)i.ns due to the coexi.tence wi.h the Yb^(3+). Fi.ally, for the fi.st ti.e, anti.acteri.l tests by mean of the di.ect contact method were p.rformed for Yi. co-dop.d wi.h p.^(3+)and Yb^(3+)and i. i. shown that, relati.ely hi.h dosages of p.^(3+) cati.ns favored the acti.i.y agai.st S. aureus, therefore, a new bi.logi.al p.op.rty for Yi. dop.d wi.h rare earths i. p.esented.
