Time to anoxia: Observations and predictions of oxygen drawdown following coastal flood events

open access: yesGeoderma
The coastal terrestrial-aquatic interface (TAI) is a highly dynamic system characterized by strong physical, chemical, and biological gradients. In particular, shifting soil redox conditions and consumption of terminal electron acceptors, due in part to ...

Cellular Hypoxia of Pancreatic β-Cells Due to High Levels of Oxygen Consumption for Insulin Secretion in Vitro*

open access: yesJournal of Biological Chemistry, 2011
Cellular oxygen consumption is a determinant of intracellular oxygen levels. Because of the high demand of mitochondrial respiration during insulin secretion, pancreatic β-cells consume large amounts of oxygen in a short time period.

Oxygen consumption by Pediococcus halophilus.

open access: yesAgricultural and Biological Chemistry, 1985
The behavior toward oxygen of several strains of Pediococcus halophilus was studied. Although these organisms are generally regarded as facultative anaerobes, this investigation showed that resting cells of P. halophilus consumed oxygen at the expense of p-giucose or L-lactate as substrate.The oxygen consuming activities among strains of soy pediococci

Perfluorocarbon nanoparticles enhance reactive oxygen levels and tumour growth inhibition in photodynamic therapy

open access: yesNature Communications, 2015
Photodynamic therapy (PDT) kills cancer cells by converting tumour oxygen into reactive singlet oxygen (1O2) using a photosensitizer. However, pre-existing hypoxia in tumours and oxygen consumption during PDT can result in an inadequate oxygen supply ...

Characterization of oxygen uptake and mass transfer in flocculent yeast cell cultures with or without a flocculent additive [PDF]

open access: yes, 1996
The effect of solids concentration and the presence of the charged polymeric additive Magna Floc LT25 on gas-liquid oxygen transfer and oxygen consumption rates have been evaluated for flocculent yeast cells grown in batch fermentations.
