Effect of varying driving pressure and respiratory rate on ventilator‐induced lung injury in healthy and injured lungs: An experimental animal study

The Journal of Physiology, EarlyView.
Abstract figure legend Top: experimental groups for the two series of rats: five combinations of driving pressure (DP) and respiratory rate (RR), maintaining a constant 4DP+RR value of 140, were applied for 4 h in healthy lungs (Series 1) and 2 h in HCl‐injured lungs (Series 2).

Transcranial Doppler ultrasound validation of BOLD‐fMRI cerebral blood flow relationship

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 939-950, February 2026.
Abstract Purpose A precise understanding of the interplay between cerebral blood flow (CBF) and blood oxygen level‐dependent (BOLD) fMRI signals is essential for advancing cerebrovascular research. Although calibrated BOLD approaches often rely on arterial spin labelling (ASL) to estimate CBF, alternative validation using transcranial Doppler ...

Blood buffers: The viewpoint of a biochemist

Physiological Reports
Mammalian blood is a very complex system whose multiple physiological roles require that its pH is maintained constant, in spite of the necessity of carrying over 15 moles of CO2 a day from the tissues to the lungs. The blood pH is maintained constant by

Quantification of the cerebral pressure–flow relationship directional sensitivity: Reliability of shorter repeated squat–stand durations

Experimental Physiology, Volume 111, Issue 2, Page 357-374, 1 February 2026.
Abstract The magnitude of changes in middle cerebral artery mean blood velocity (MCAv) is attenuated when mean arterial pressure (MAP) increases compared with when MAP decreases. This directional sensitivity has been characterized using a time‐corrected ratio calculated on MCAv and MAP changes induced by repeated squat–stands (RSS) at 0.05 and 0.10 Hz ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

Experimental Physiology, Volume 111, Issue 2, Page 527-538, 1 February 2026.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...
