Spatial Variations in Vitreous Oxygen Consumption. [PDF]

open access: yesPLoS 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 ...

Maximal oxygen consumption and oxygen uptake efficiency in adolescent males

open access: yesJournal 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

open access: yesMolecules, 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

open access: yesMetabolism 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

open access: yesCritical 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.

Anaesthesia-Specifi c Oxygen Transport Assessment in Robot-Assisted Pelvic Surgery: a Clinical Trial

open access: yesКреативная хирургия и онкология, 2021
Background. Robot-assisted pelvic surgery rapidly becomes a choice in surgeries for gynaecological oncology and urology. These interventions require special settings (pneumoperitonaeum and Trendelenburg position), which inevitably and systemically impact

Shelf Life Prediction of Milk Powder Based on Changes in Headspace Oxygen Concentration in Packaging [PDF]

open access: yesShipin Kexue, 2023
Purpose: To predict the shelf life of milk powder based on the change of oxygen concentration in the packaging headspace. Methods: The relative oxygen consumption rate was used to characterize the oxidation characteristics of whole milk powder, and the ...

Baseline oxygen consumption decreases with cortical depth.

open access: yesPLoS Biology, 2022
The cerebral cortex is organized in cortical layers that differ in their cellular density, composition, and wiring. Cortical laminar architecture is also readily revealed by staining for cytochrome oxidase-the last enzyme in the respiratory electron ...
