Acute and potentially persistent effects of scuba diving on the blood transcriptome of experienced divers
Eftedal, Ingrid; Ljubkovic, Marko; Flatberg, Arnar; Jørgensen, Arve; Brubakk, Alf O; Dujic, Zeljko (Journal article; Peer reviewed, 2013)During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress ... -
Blood gene expression and vascular function biomarkers in professional saturation diving
Kiboub, Fatima Zohra; Møllerløkken, Andreas; Hjelde, Astrid; Flatberg, Arnar; Loennechen, Øyvind; Eftedal, Ingrid (Journal article; Peer reviewed, 2018)Saturation diving is an established way to conduct subsea operations with human intervention. While working, the divers must acclimatize to the hyperbaric environments. In this study, genome-wide gene expression and selected ... -
Functional profiling reveals altered metabolic activity in divers’ oral microbiota during commercial heliox saturation diving
Monnoyer, Roxane; Eftedal, Ingrid; Hjelde, Astrid; Deb, Sanjoy Kumar; Haugum, Kjersti; Lautridou, Jacky (Peer reviewed; Journal article, 2021)Background: The extreme environment in saturation diving affects all life forms, including the bacteria that reside on human skin and mucosa. The oral cavity alone is home to hundreds of different bacteria. In this study, ... -
Immune and inflammatory responses to freediving calculated from leukocyte gene expression profiles
Eftedal, Ingrid; Flatberg, Arnar; Drvis, Ivan; Dujic, Zeljko (Journal article; Peer reviewed, 2016)Freedivers hold their breath while diving, causing blood oxygen levels to decrease (hypoxia) while carbon dioxide increases (hypercapnia). Whereas blood gas changes are presumably involved in the progression of respiratory ... -
Quantification of guanine-derived urinary biomarkers of oxidative stress in saturation divers by LC-MS/MS
Lund, Hedda Juni (Master thesis, 2022)Metningsdykkere jobber under konstant trykksatte omgivelser med forhøyet deltrykk av oksygen for opp til flere uker. Dette kan føre til oksidativt stress, hvilket er assosiert med en rekke sykdommer, både akutte og kroniske. ... -
Shifts in the oral microbiota during a four-week commercial saturation dive to 200 meters
Monnoyer, Roxane; Haugum, Kjersti; Lautridou, Jacky; Flatberg, Arnar; Hjelde, Astrid; Eftedal, Ingrid (Peer reviewed; Journal article, 2021)During commercial saturation diving, divers live and work under hyperbaric and hyperoxic conditions. The myriads of bacteria that live in and on the human body must adjust to the resultant hyperbaric stress. In this study, ...
