The modified Borg cycle strength test (mBCST): Feasibility and physiological response in people with COPD and healthy older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Accurate prescription of supramaximal exercise requires exercise tests covering the intensity domain between maximal aerobic and peak power output. All‐out tests are commonly used for this objective but are considered challenging for people with chronic obstructive pulmonary disease (COPD) due to the extreme physiological demand.

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

open access: yesExperimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

open access: yesExperimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Persistence of fatigue in the absence of pathophysiological mechanisms in some patients more than 2 years after the original SARS‐CoV‐2 infection

open access: yesExperimental Physiology, EarlyView.
Abstract Following an acute infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), a substantial percentage of patients report the persistence of debilitating symptoms, often grouped in a syndrome termed ‘long COVID’. We sought to identify potential pathophysiological mechanisms responsible for the persistence, in some long COVID ...
