Excessive exposure to solar radiation induces injurious effects on human skin. Our previous study evidenced that protocatechuic acid (P0) and ethyl protocatechuate (P2) act against photodamage and photoaging. The present study aimed to develop solid lipid nanoparticles (SLNs) and nanostructured

Recently a family of O(2)-dependent prolyl hydroxylase domain-containing enzymes (PHD) has been identified as a cellular oxygen-sensing mechanism. Reduced prolyl hydroxylase activity initiates a signalling cascade that includes the accumulation, as well as the activation, of hypoxia-inducible factor (HIF-1alpha). In

The mitochondrial permeability transition (MPT) plays an important role in hepatocyte death caused by ischemia-reperfusion (IR). This study investigated whether activation of the cellular oxygen-sensing signal cascade by prolyl hydroxylase inhibitors (PHI) protects against the MPT after hepatic IR. Ethyl
