Spatial Variations in Vitreous Oxygen Consumption. [PDF]

PLoS ONE, 2016
We investigated the spatial variation of vitreous oxygen consumption in enucleated porcine eyes. A custom made oxygen source was fabricated that could be localized to either the mid or posterior vitreous cavity and steady state vitreous oxygen tension ...

Effects of Harmful Algal Blooms on Fish: Insights from Prymnesium parvum [PDF]

Fishes, 2018
Blooms of the planktonic alga Prymnesium parvum pose a global threat, causing fish kills worldwide. Early studies on the exposure of fish to P. parvum indicate that toxic effects are related to gill damage.

Maximal oxygen consumption and oxygen uptake efficiency in adolescent males

Journal of Exercise Science & Fitness, 2021
Background/objective: Measures of oxygen uptake efficiency (OUE) have been used to evaluate cardiorespiratory fitness (CRF) in adolescents unable to perform maximal exercise. The oxygen uptake efficiency slope (OUES) and oxygen uptake efficiency plateau (

Influence of Oxygen Management on Color and Phenolics of Red Wines

Molecules, 2023
Winemaking involves contact at different stages with atmospheric oxygen, the consumption of which determines its final properties. The chemical analysis of red wines subjected to consecutive cycles of air saturation has been extensively researched ...

SGLT2 inhibition reduces myocardial oxygen consumption

Metabolism Open, 2022
Aims/hypothesis: SGLT2 inhibition is associated with a reduced risk of cardiac disease that is still largely unexplained. According to one hypothesis, improved myocardial energetics may explain the cardioprotective effects of SGLT2i.

The Effect of a Single Dose of Thiamine on Oxygen Consumption in Patients Requiring Mechanical Ventilation for Acute Illness: A Phase II, Randomized, Double-Blind, Placebo-Controlled Trial

Critical Care Explorations, 2021
IMPORTANCE:. Lower oxygen consumption is associated with worse survival in septic shock and in other forms of critical illness. No treatment that increases oxygen extraction, a key determinant of oxygen consumption, has been found.

Bottom mixed layer oxygen dynamics in the Celtic Sea [PDF]

, 2020
The seasonally stratified continental shelf seas are highly productive, economically important environments which are under considerable pressure from human activity.

Looking beyond stratification: a model-based analysis of the biological drivers of oxygen deficiency in the North Sea [PDF]

, 2016
Low oxygen conditions, often referred to as oxy- gen deficiency, occur regularly in the North Sea, a temperate European shelf sea. Stratification represents a major process regulating the seasonal dynamics of bottom oxygen, yet, low- est oxygen ...

Dynamic characteristics of oxygen consumption

BioMedical Engineering OnLine, 2018
Background Previous studies have indicated that oxygen uptake ($$VO_2$$ VO2 ) is one of the most accurate indices for assessing the cardiorespiratory response to exercise.
