Prominent role of exopeptidase DPP III in estrogen-mediated protection against hyperoxia in vivo

Redox Biology, 2016
A number of age-related diseases have a low incidence in females, which is attributed to a protective effect of sex hormones. For instance, the female sex hormone estrogen (E2) has a well established cytoprotective effect against oxidative stress, which ...

Systematic investigation of changes in oxidized cerebral cytochrome c oxidase concentration during frontal lobe activation in healthy adults [PDF]

, 2012
Using transcranial near-infrared spectroscopy (NIRS) to measure changes in the redox state of cerebral cytochrome c oxidase (Δ[oxCCO]) during functional activation in healthy adults is hampered by instrumentation and algorithm issues.

LAT1/SLC7A5‐mediated amino acid uptake is regulated by redox signals triggered by formyl‐peptide receptor 2

The FEBS Journal, Volume 293, Issue 9, Page 2637-2655, May 2026.
FPR2 activation mediates NOX‐dependent LAT1 expression and, in turn, promotes mTORC1 signaling. Upon stimulation with WKYMVm, the FPR2‐NOX2‐ROS axis upregulates LAT1 via increased c‐Myc phosphorylation and decreased miR‐126. Additionally, it promotes CD98 translocation to the plasma membrane.

Oxygen Stewardship in Adult Critical Care: A Quality Improvement Initiative

Nursing in Critical Care, Volume 31, Issue 3, May 2026.
ABSTRACT Background Oxygen therapy is commonly administered in critical care, yet patients frequently receive oxygen above recommended saturation targets. Excessive oxygen exposure may contribute to avoidable harm and unnecessary resource use. Despite guideline recommendations, reliable adherence to oxygen titration targets in routine intensive care ...

Xenoperfusion—The Transformative Role of Machine Perfusion in Xenotransplantation

Xenotransplantation, Volume 33, Issue 3, May/June 2026.
ABSTRACT Recent advances in xenotransplantation have gained substantial public and clinical attention as genetically modified porcine organs are now being transplanted into living human recipients. While only case reports have been published to date, the first clinical trials for kidney xenotransplantation are now ongoing.

Influence of low‐dose dopamine on exercise in fibrosing interstitial lung disease

Experimental Physiology, Volume 111, Issue 5, Page 2682-2695, 1 May 2026.
ABSTRACT Fibrotic interstitial lung disease (FILD) is associated with dyspnoea and exercise intolerance. In other cardiorespiratory conditions, heightened carotid body (CB) chemoreflex sensitivity is associated with reduced exercise capacity. We tested the hypothesis that CB chemoreflex inhibition would improve exercise endurance time (EET) and reduce ...

Oxygen diffusion kinetics, buffering capacity and phenotype: A narrative review of oxygen physiology and later phenotype in very preterm infants

Experimental Physiology, Volume 111, Issue 5, Page 2485-2493, 1 May 2026.
Abstract Clinicians often view exposure to supplementary oxygen in preterm infants as a simple reciprocal trade‐off between mortality and the risk of vision‐threatening retinopathy, but this perspective oversimplifies the underlying physiology. Oxygen moves through a series of spatially distinct compartments without intrinsic regulation, with Fick's ...
