Thank you for that pdf file dear Kenan ., Please either PM me or add here any pdf files that you think are relevant to Oxygen and its metabolic reactions..
Incidentally I worked in this field with a well known Biophysicist on Oxidative Phosphorylation and free radical chemistry in biology and published more than 20 papers ., my most recent work on that was pubed in Nature last year March., It is very complicated and blaming Tissue damage due free radicals is only one problem..
The pdf file is a some sort of semi review for Doctors.., They are right in certain aspects for e.g.
100% oxygen can be tolerated at sea level for about 24- 48 hours without any serious tissue damage
this oxygen toxicity indeed is a serious problem with patients that can not move and worse specially with COPD patients., it is in fact a wrong method to treat such people as ARDS guys on ventilators woth 100% O2 ., But the game become quickly different with healthy people that are good enough to consume oxygen and generate ATP + controlled free radicals where they are needed..
The pulsed oxygen therapy is becoming more popular in well known hyperbaric research centers in west
I would say free radicals in biology are as important as ATP synthesis for the growth of an organism with these side reactions controlling deleterious biology that is detrimental to a given organism..
Any way thanks for that paper ..please feel free to discuss..
with best wishes
