Hyperbaric oxygen therapy (HBOT) is a therapeutical approach based on exposure to pure
oxygen in an augmented atmospheric pressure. Although it has been used for years, the …

Underwater activities are characterized by an imbalance between reactive oxygen/nitrogen
species (RONS) and antioxidant mechanisms, which can be associated with an …

Long COVID-19 patients show systemic inflammation and persistent symptoms such as
fatigue and malaise, profoundly affecting their quality of life. Since improving oxygenation …

Exercise generates reactive oxygen species (ROS), creating a redox imbalance towards
oxidation when inadequately intense. Normobaric and hyperbaric oxygen (HBO) breathed …

Pulmonary oxygen toxicity (POT) is a major risk in diving while breathing hyperoxic gas and
is also considered in clinical hyperbaric oxygen treatment. The POTindex calculated by the …

Oxygen is a powerful trigger for cellular reactions and is used in many pathologies, including
oxidative stress. However, the effects of oxygen over time and at different partial pressures …

In this study, the metabolic responses of hypoxic breathing for 1 h to inspired fractions of
10% and 15% oxygen were investigated. To this end, 14 healthy nonsmoking subjects (6 …

Purpose Divers can experience cognitive impairment due to inert gas narcosis (IGN) at
depth. Brain-derived neurotrophic factor (BDNF) rules neuronal connectivity/metabolism to …

Freeskiing is performed in an extreme environment, with significant physical effort that can
induce reactive oxygen species (ROS) generation and dehydration. This study aimed to …

Inflammation is an adaptive response to both external and internal stimuli including
infection, trauma, surgery, ischemia-reperfusion, or malignancy. A number of studies …
