recommendations! Published in 2018 at "Journal of Applied Toxicology"

DOI: 10.1002/jat.3646

Abstract: The neurotoxicity of lead (Pb) is well established, and oxidative stress is strongly associated with Pb‐induced neurotoxicity. Heme oxygenase 1 (HO‐1) is an important antioxidative enzyme for protection against oxidative stress in many disease models.… read more here.

DOI: 10.1016/j.bcp.2019.01.011

Abstract: Graphical abstract Figure. No caption available. &NA; Metamizole is an analgesic and antipyretic, but can cause neutropenia and agranulocytosis. We investigated the toxicity of the metabolites N‐methyl‐4‐aminoantipyrine (MAA), 4‐aminoantipyrine (AA), N‐formyl‐4‐aminoantipyrine (FAA) and N‐acetyl‐4‐aminoantipyrine (AAA)… read more here.
