Pulmonary oxygen uptake and muscle deoxygenation kinetics during recovery in trained and untrained male adolescents [PDF]

, 2011
Previous studies have demonstrated faster pulmonary oxygen uptake ( V ˙ O 2 ) kinetics in the trained state during the transition to and from moderate-intensity exercise in adults. Whilst a similar effect of training status has previously been observed

Photobiomodulation and platelet‐rich fibrin in the gastrocnemius muscle submitted to calcaneal tendinopathy in rats

Photochemistry and Photobiology, EarlyView.
The study evaluated different treatments for calcaneal tendinopathy in rats, focusing on the gastrocnemius muscle. Photobiomodulation (PBM), advanced platelet‐rich fibrin (A‐PRF), and their combination were tested. Treated animals showed improved muscle strength between 7 and 21 days, but without significant recovery of muscle fibers.

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

Experimental 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 ...

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue

Experimental Physiology, EarlyView.
Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.

Neuroprotective mechanisms of creatine occur in the absence of mitochondrial creatine kinase

Neurobiology of Disease, 2004
There is substantial evidence that creatine administration exerts neuroprotective effects both in vitro and in vivo. The precise mechanisms for these neuroprotective effects however are as yet unclear.

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

Experimental 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 ...

Bioenergetic dysfunction in Huntington's disease human cybrids [PDF]

, 2011
In this work we studied the mitochondrial-associated metabolic pathways in Huntington's disease (HD) versus control (CTR) cybrids, a cell model in which the contribution of mitochondrial defects from patients is isolated.

Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

Experimental Physiology, EarlyView.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...
