The aim of the research part of my PhD is to look further into some of the biochemical reactions linked to decompression sickness. Tetrahydrobiopterin (BH4) is an essential cofactor of the enzyme Nitric Oxide Synthase (NOS). NOS produces Nitric oxide (NO), a signal molecule responsible for vasodilation, and its bioavailability is important for endothelial function. What happens to the NOS enzyme, and NO production, when its cofactor (BH4) is oxidized during a dive? How can this be related to decompression sickness? Are there potent antioxidants that can maintain the bioavailability of BH4? These are questions I am trying to find the answer to.

My PhD is part of a project titled; "Tetrahydrobiopterin as a key factor in the pathophysiology of diving". Keywords: BH4, hyperoxia and diving.
