FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

DC-DC transformer multiphase converter with transformer coupling for two-stage architecture
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010 This paper presents an analysis of a very high efficiency topology based on a multiphase converter where the coupling among the phases is done by means of transformers. Since energy is not stored in the transformers, it is transferred directly from the input to the output. This topology along with its control strategy, were previously reported in state

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.
