Over 2000 publications including more than 100 human studies seem to indicate that
humans have only recently benefited from or known about the medical effects of H2 within …

In Special Operations Forces (SOF) closed-circuit rebreathers with 100% oxygen are
commonly utilized for covert diving operations. Exposure to high partial pressures of oxygen …

The term “normobaric oxygen paradox”(NOP), describes the response to the return to
normoxia after a hyperoxic event, sensed by tissues as oxygen shortage, and resulting in up …

Cardiac function depends mainly on mitochondrial metabolism. Cold conditions increase the
risk of cardiovascular diseases by increasing blood pressure. Adaptive thermogenesis leads …

Recently, several studies have highlighted the tight connection between mitochondria and
physical activity. Mitochondrial functions are important in high-demanding metabolic …

Oxygen is a fundamental element for the life of a large number of living organisms allowing
an efficient energetic utilization of substrates. Organisms relying on oxygen evolved complex …

Background: The activity of antioxidant enzymes and sirtuins (Sirt) decreases along with
age, which is counteracted by aerobic training. Sirtuins increase antioxidant defence. Whole …

Heat shock proteins (HSPs) have protective effects against oxidative stress and
decompression sickness. Nitric oxide may reduce bubble formation during decompression …

Abstract “Cutis Marmorata” skin symptoms after diving, most frequently in the form of an
itching or painful cutaneous red-bluish discoloration are commonly regarded as a mild form …

SCUBA diving poses risks due to pressure changes during descent (compression) and
ascent (decompression). Decompression sickness (DCS) occurs due to gas bubble …
