Hydroquinone-Based Synthesis of Pd Nanostructures and the Interplay of Surface Capping, Reduction Kinetics, Attachment Diffusion, and Fusion

, 2021
The rational synthesis of nanostructured materials with desired properties calls for a thorough understanding of the growth mechanism. Here we report a mechanistic case study of Pd nanostructures synthesized by reducing a Pd­(II) precursor with ...

Elucidation of the 4-hydroxyacetophenone catabolic pathway in Pseudomonas fluorescens ACB [PDF]

, 2008
The catabolism of 4-hydroxyacetophenone in Pseudomonas fluorescens ACB is known to proceed through the intermediate formation of hydroquinone. Here we provide evidence that hydroquinone is further degraded through 4-hydroxymuconic semialdehyde and ...

Hydroquinone Induces NLRP3-Independent IL-18 Release from ARPE-19 Cells

Cells, 2021
Age-related macular degeneration (AMD) is a retinal disease leading to impaired vision. Cigarette smoke increases the risk for developing AMD by causing increased reactive oxygen species (ROS) production and damage in the retinal pigment epithelium (RPE).
