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

The cellular oxygen sensor is a family of oxygen-dependent proline hydroxylase domain (PHD)-containing enzymes, whose reduction of activity initiate a hypoxic signal cascade. In these studies, prolyl hydroxylase inhibitors (PHIs) were used to activate the PHD-signaling pathway in cardiomyocytes. PHI-pretreatment

Protection from a prolyl hydroxylase domain-containing enzyme (PHD) inhibitor, desferoxamine (DFO), was recently reported to be dependent on production of reactive oxygen species (ROS). Ischemic preconditioning triggers the protected state by stimulating nitric oxide (NO) production to open mitochondrial ATP-sensitive
