Chiral Nanoparticles Suppress Inflammatory Infiltration to Promote Extracellular Matrix Remodeling for Ectopia Lentis Therapy

open access: yesAdvanced Science, EarlyView.
L‐cysteine‐configured chiral polyurethane nanoparticles suppress ocular inflammation and reduce extracellular matrix (ECM) degradation in ectopia lentis by regulating macrophages polarization and inhibiting nuclear factor kappa B signaling pathway. By promoting zonular fiber‐associated protein restoration and tissue repair, this minimally invasive ...

Sulfuric acid as autocatalyst in the formation of sulfuric acid

open access: yes, 2016
Sulfuric acid can act as a catalyst of its own formation. We have carried out a computational investigation on the gas-phase formation of H 2SO4 by hydrolysis of SO3 involving one and two water molecules, and also in the presence of sulfuric acid and its
