Phenyl arsine oxide (PAO) is a vesicant, similar to Lewisite, a potential chemical warfare agent and an environmental contaminant. PAO-induced skin burns can trigger acute organ injury, including lungs. We have recently demonstrated that PAO burns can also has a delayed toxicity, although the specific mechanism/s remain to be determined.

This study investigates the therapeutic potential of hyaluronic acid/proanthocyanidin (HA/PAC) nanoparticles in treating alkali-induced corneal burns. Alkali burns are common ocular emergencies that can lead to severe vision impairment if not promptly and properly treated. The low water solubility of proanthocyanidins (PACs), which are potent antioxidant and anti-inflammatory agents, limits their bioavailability and therapeutic efficacy.

The present experiment aimed to formulate four ointments that included mixtures of plant extracts (, , , and ), apitherapy products (honey, propolis, and apilarnil) and natural polymers (collagen, chitosan, and the lyophilisate of egg white) in an ointment base. : In order to investigate the therapeutic properties of the ointments, experimental in vivo injury models (linear incision, circular excision, and thermal burns) were performed on laboratory animals, namely Wistar rats. The treatment was applied topically, once a day, for 21 days.

Purpose: To evaluate the severity distribution of chemical burn-induced Limbal stem cell deficiency (LSCD) according to the novel global consensus classification and to compare the treatment approach, before and after the global consensus.
Methods: Medical records of 127 eyes of 109 patients with LSCD were included. LSCD stages were categorized according to the global consensus classification published by "International LSCD Working Group".
Peripheral Evolution of Tanshinone IIA and Cryptotanshinone for Discovery of a Potent and Specific NLRP3 Inflammasome Inhibitor.

Natural products (NPs) continue to serve as an invaluable source in drug discovery, and peripheral evolution of NPs is a highly efficient evolution strategy. Herein, we describe a unified "methyl to amide" peripheral evolution of Tanshinone IIA and Cryptotanshinone for discovery of NLRP3 inflammasome inhibitors. There were 54 compounds designed and prepared, while the chemoinformatic analysis revealed that these evolved NP analogues occupy a unique chemical space.
