Shifts in the Oral Microbiota During a Four-Week Commercial Saturation Dive to 200 Meters

Frontiers in Physiology, 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.

Functional Profiling Reveals Altered Metabolic Activity in Divers’ Oral Microbiota During Commercial Heliox Saturation Diving

Frontiers in Physiology, 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.

Heliox Improves Carbon Dioxide Removal during Lung Protective Mechanical Ventilation

Critical Care Research and Practice, 2014
Introduction. Helium is a noble gas with low density and increased carbon dioxide (CO2) diffusion capacity. This allows lower driving pressures in mechanical ventilation and increased CO2 diffusion.

Side‐Gate Modulation of Supercurrent in InSb Nanoflag‐Based Josephson Junctions

physica status solidi (b), EarlyView.
Proximitized InSb nanoflags are a promising platform for unconventional superconductivity, due to their strong spin–orbit coupling, their highly transparent interfaces, and their electrostatic tunability via global gating. In this work, it is shown that superconductivity in InSb nanoflags can be further tuned by means of metallic side gates, and the ...

Airway stenosis: classification, pathogenesis, and clinical management

MedComm, Volume 6, Issue 2, February 2025.
The development of AS can be affected by many factors, and fibrosis is the core process. Inflammation, Epithelial–mesenchymal transition and metabolic reprogramming can accelerate the development of AS by promoting the process of fibrosis. And the rest also show the correlation with AS.

Sex differences in exercise‐induced arterial hypoxemia and pulmonary edema following high‐intensity exercise in highly trained endurance athletes

Physiological Reports, Volume 13, Issue 1, January 2025.
Abstract This study investigated sex differences in the development of pulmonary edema and exercise‐induced arterial hypoxemia (EIAH) in well‐trained endurance athletes during near‐maximal exercise in a real‐world setting. Twenty participants (10M vs. 10F; V̇O2peak: 69.3 (8.8) vs. 50.7 (4.1) ml∙kg−1∙min−1) underwent a maximal incremental treadmill test

Room air dilution of heliox given by facemask [PDF]

Intensive Care Medicine, 2008
To measure the extent of dilution of helium-oxygen (heliox) by room air when given via high concentration reservoir mask to spontaneously breathing subjects. Substantial dilution of heliox by room air under these circumstances might alter its physical properties sufficiently to negate any potential clinical benefit in obstructive respiratory failure ...

To what extent do physiological tolerances determine elevational range limits of mammals?

The Journal of Physiology, Volume 602, Issue 21, Page 5475-5484, 1 November 2024.
Abstract figure legend Hypothetical relationship between elevational range limits and capacity for aerobic thermogenesis (thermogenic maximal oxygen uptake) in hypoxia. In this hypothetical comparison between highland and lowland sister species, which is consistent with empirical data for small mammals, the species with the higher elevational range ...

Vocal development through morphological computation. [PDF]

PLoS Biology, 2018
The vocal behavior of infants changes dramatically during early life. Whether or not such a change results from the growth of the body during development-as opposed to solely neural changes-has rarely been investigated. In this study of vocal development
