Laggner H, Schmid S, Goldenberg H. Hypericin and photodynamic treatment do not interfere with transport of vitamin C during respiratory burst. Free Radic Res. 2004;38:1073-81 pubmed
..Results from this work indicate that ascorbate transport per se is not altered during photodynamic therapy and vitamin C does not interfere with hypericin-induced photodamage of cellular targets. ..
Laggner H, Gmeiner B. Investigating the role of Hâ‚‚S in 4-HNE scavenging. Methods Enzymol. 2015;555:3-18 pubmed publisher
..Assuming that the low-molecular thiol H2S may react with 4-HNE, methods to monitor the ability of H2S to counteract the protein-modifying and cytotoxic activity of 4-HNE are described in this chapter. ..

. The uremic toxin indoxyl sulfate acts as a pro- or antioxidant on LDL oxidation. Free Radic Biol Med. 2014;75 Suppl 1:S36 pubmed publisher
..A scheme for the generation of tryptanthrine from IS via indoxyl radicals is proposed, which may facilitate LDL lipid oxidation. Our observations add further insight in the Janus-faced properties of this important uremic toxin. ..
