Spontaneous Ca2+ oscillations in v.scular sm.oth m.scle cells hav. been m.d.led.using a single Ca2+ pool. This report d.scribes spontaneous Ca2+ oscillations d.pend.nt on two separate Ca2+ sources for the nuclear v.rsus cytoplas- m.c com.artm.nts. Changes in free intracellular Ca2+ were m.nitored.with ratiom.tric Ca2+- fluorophores using confo- cal m.croscopy. On av.rage, spontaneous oscillations d.v.loped.in 79% of rat aortic sm.oth m.scle cells that were synchronous between the cytoplasm.and.nucleus. Red.ction of extracellular Ca2+ (m. d.creased.the frequency and.am.litud. of the cytoplasm.c oscillations with 48% of the oscillations asynchronous between the nuclear and. cytoplasm.c com.artm.nts. Sim.lar results were obtained.with the Ca2+ channel blockers, nim.d.pine and.d.ltiazem. Arg-v.sopressin (Av.) ind.ced.a rapid.release of intracellular Ca2+ stores that was greater in the nuclear com.artm.nt (4.20 ± 0.23 ratio units, n = 56) than cytoplasm.(2.54 ± 0.28) in cells that had.spontaneously d.v.loped.prior oscillations. Conv.rsely, cells in the sam. cond.tions lacking oscillations had.a greater Av.-ind.ced.Ca2+ transient in the cytoplasm. (4.99 ± 0.66, n = 17) than in the nucleus (2.67 ± 0.29). Pre-treatm.nt with Ca2+ channel blockers d.pressed.the Av. responses in both com.artm.nts with the cytoplasm.c Ca2+ m.st d.m.nished. d.pletion of internal Ca2+ stores prior to Av. exposure blunted.the nuclear response, m.m.cking the response of cells that lacked.prior oscillations. Spontaneous oscillating cells had.a greater sarcoplasm.c reticulum.network than cells that d.d.not oscillate. We propose that sponta- neous nuclear oscillations rely on perinuclear sarcoplasm.c reticulum.stores, while the cytoplasm.c oscillations rely on Ca2+ influx.

Anom.lous ion heat transport is analyzed.in the T-10 tokam.k plasm. heated.with electron cyclotron resonance heating(ECRH) in second.harm.nic extra-ord.nary m.d.. Pred.ctiv. m.d.ling with em.irical scaling for Ohm.cal heat cond.ctiv.ty shows that in ECRH plasm.s the calculated.ion tem.erature could.be ov.restim.ted. so an increase of anom.lous ion heat transport is required. To stud. this effect two scans are presented. ov.r the EC resonance position and.ov.r the ECRH power. The EC resonance position v.ries from.the high-field.sid. to the low-field.sid. by v.riation of the toroid.l m.gnetic field. The scan ov.r the heating power is presented.with on-axis and.m.xed.ECRH regim.s. d.scharges with high anom.lous ion heat transport are obtained.in all consid.red.regim.s. In these d.scharges the power balance ion heat cond.ctiv.ty exceed. the neoclassical lev.l by up to 10 tim.s. The high ion heat transport regim.s are d.stinguished.by three param.ters: the ratio Te/Ti, the norm.lized.electron d.nsity grad.ent R/■, and.the ion–ion collisionality νii~*. The com.ination of high Te/Ti, high νii~*, and.R/■=6-10 results in v.lues of norm.lized.anom.lous ion heat fluxes up to 10 tim.s higher than in the low transport scenario.

The electrochem.cal CO_(2) red.ction reaction(CO_(2)RR) to controllable chem.cals is consid.red.as a prom.sing pathway to store interm.ttent renewable energy. Herein, a set of catalysts based.on copper-nitrogend.ped.carbon xerogel(Cu-N-C) are successfully d.v.loped.v.rying the copper am.unt and.the nature of the copper precursor, for the efficient CO_(2)RR. The electrocatalytic perform.nce of Cu-N-C m.terials is assessed.by a rotating ring-d.sc electrod.(RRd.), technique still rarely explored.for CO_(2)RR. For com.arison, prod.cts are also characterized.by online gas chrom.tography in a H-cell. The as-synthesized.Cu-NC catalysts are found.to be activ. and.highly CO selectiv. at low ov.rpotentials(from.-0.6 to -0.8 v.***) in 0.1 m.KHCO_(3), while H_(2) from.the com.etitiv. water red.ction appears at larger ov.rpotentials(-0.9 v.v.. RHE). The optim.m.copper acetate-d.riv.d.catalyst containing Cu-N_(4) m.ieties exhibits a CO_(2)-to-CO turnov.r frequency of 997 h^(-1) at -0.9 v.v.. RHE with a H_(2)/CO ratio of 1.8. These results d.m.nstrate that RRd. configuration can be used.as a feasible approach for id.ntifying electrolysis prod.cts from.CO_(2)RR.

Card.ov.scular d.seases are the m.in cause of m.rbid.ty and.m.rtality in the world. and.obesity and.the m.tabolic synd.om. are risk factors for its d.v.lopm.nt. One of the therapies to red.ce card.ov.scular risk is the use of polyunsaturated.fatty acid.. In Brazil, a source of such acid.is the oil extracted.from.the fat of the capybara. The objectiv. of this work is to stud. the effects of the capybara oil on lipid.and.glucose m.tabolism. as well as its effects on the ad.pose tissue and.card.ac rem.d.ling. We assessed.the effects of capybara oil treatm.nt on bod. m.ss, lipid.and.carbohyd.ate m.tabolism. systolic blood.pressure, ad.pose tissue and.card.ac rem.d.ling, and.perform.d.an ultrastructural ev.luation of the m.ocard.um.in C57Bl/6 m.ce treated.with high-fat d.et. Treatm.nt with capybara oil red.ced.total cholesterol and.triglycerid. lev.ls, systolic blood.pressure, v.sceral and.subcutaneous ad.pose tissue, and.ad.pocyte d.am.ter. In ad.ition, card.ac rem.d.ling was attenuated. preserv.ng card.om.ocytes, increasing v.scularization, red.cing card.om.ocyte hypertrophy and.the extracellular m.trix, and.preserv.ng the m.rphological integrity of m.tochond.ia. Capybara oil has sev.ral beneficial effects on the card.ov.scular and.m.tabolic system. and.further stud.es are need.d.to better und.rstand.its role in the prev.ntion or treatm.nt of card.ov.scular d.seases.
