Background: Neurodevelopm.ntal abnorm.lities in fetal alcohol spectrum.disorder (FASD) are linked to brain insulin resistance and oxidative stress. However, the role of thiam.ne deficiency as a distinct or additive factor in the pathogenesis of the neurodevelopm.ntal and m.tabolic derangem.nts in FASD has not been determ.ned. m.thods: Control and ethanol-exposed hum.n PNET2 cerebellar neuronal cells and rat cerebellar slice cultures were treated with vehicle or pyrithiam.ne (Pyr) to assess independent and additive effects of thiam.ne deficiency on ethanol-m.diated neurotoxicity, m.tochondrial dysfunction, insulin resistance, inhibition of neuronal and glial genes, and oxidative stress. Results: Pyr treatm.nts (0 - 200 µm. caused dose-dependent cell loss (Crystal Violet assay) and reduced m.tochondrial function (m.T assay) in PNET2 neuronal cultures. Ethanol alone (100 m.) significantly reduced PNET2 neuronal viability, m.T activity, and ATP production. Over the broad dose range of Pyr treatm.nt, ethanol significantly reduced ATP content and cell num.er and increased m.tochondrial m.ss (m.toTracker Green). Ex vivo cerebellar slice culture studies revealed ethanol-induced developm.ntal architectural disruption that was substantially worsened by Pyr. The adverse effects of ethanol were linked to increased lipid peroxidation and inhibition of asparatyl-asparaginyl-β-hydroxylase (ASPH) expression. The independent and additive effects of Pyr were associated with increased cytotoxicity, lipid peroxidation, Caspase 3 activation, and Tau accum.lation. Conclusions: During developm.nt, alcohol exposure and thiam.ne deficiency exert distinct but overlapping m.lecular pathologies that ultim.tely im.air the structure and function of cerebellar neurons. While both insults drive cell loss and m.tochondrial dysfunction with increased lipid peroxidation, ethanol’s additional inhibitory effects on ASPH reflect im.airm.nts in insulin and IGF signaling. In contrast, Pyr’s m.in adverse e

Background The nationally determ.ned contribution（NDC） presented by Argentina within the fram.work of the Paris Agreem.nt is aligned with the decisions m.de in the context of the United Nations Fram.work Conven-tion on Clim.te Change（UNFCCC） on the reduction of em.ssions derived from.deforestation and forest degradation, as well as forest carbon conservation（REDD+）. In addition, clim.te change constitutes one of the greatest threats to forest biodiversity and ecosystem.services. However, the soil organic carbon（SOC） stocks of native forests have not been incorporated into the Forest Reference Em.ssion Levels calculations and for conservation planning under cli-m.te variability due to a lack of inform.tion. The objectives of this study were:（i） to m.del SOC stocks to 30 cm.of native forests at a national scale using clim.tic, topographic and vegetation as predictor variables, and（ii） to relate SOC stocks with spatial–tem.oral rem.tely sensed indices to determ.ne biodiversity conservation concerns due to threats from.high inter-annual clim.te *** We used 1040 forest soil sam.les（0–30 cm. to generate spatially explicit estim.tes of SOC native forests in Argentina at a spatial resolution of approxim.tely 200 m. We selected 52 potential predictive environm.ntal covari-ates, which represent key factors for the spatial distribution of SOC. All covariate m.ps were uploaded to the Google Earth Engine cloud-based com.uting platform.for subsequent m.delling. To determ.ne the biodiversity threats from.high inter-annual clim.te variability, we em.loyed the spatial–tem.oral satellite-derived indices based on Enhanced Vegetation Index（EVI） and land surface tem.erature（LST） im.ges from.landsat *** SOC m.del（0–30 cm.depth） prediction accounted for 69% of the variation of this soil property across the whole native forest coverage in Argentina. Total m.an SOC stock reached 2.81 Pg C（2.71–2.84 Pg C with a probability of 90%） for a total area of 460,790 km.,

The presence of an em.rging brom.nated flam. retardant, decabrom.diphenylethane （DBDPE）, has been confirm.d in Spanish sewage sludge. Thirty one sam.les from.different urban wastewater treatm.nt plants （WWTPs） were analyzed for this brom.nated flam. retardant. DBDPE was positively identified and quantified in all sam.les at lower concentrations （47.0 ± 29.7 ng/g dry weight （dw）; m.an ± SD） than those obtained for decabrom.diphenyl ether （Bde-209）（290 ± 236 ng/g dw; m.an ± SD） in a previous study. Influence of the WWTP characteristics in the pollutant levels was evaluated. No significant correlations were obtained between DBDPE concentrations and the population or sewage sludge production rate associated with the plants, neither wastewater treatm.nt m.thod. Sources of DBDPE in the sludge were also evaluated. Data indicate a com.on origin for DBDPE and Bde-209, which m.y be related to leaching processes during the use and disposal of consum.r products containing these chem.cals. Nevertheless, DBDPE contents are not influenced by industrial activities, which suggests that the infusion of DBDPE com.ercial m.xture is not a source of this chem.cal into the environm.nt, and indicates that the use of DBDPE in the Spanish industry is still low com.ared to deca-Bde.
