The Highly Conserved Cys95 Residue of Fructose‐1,6‐Bisphosphatase 1 Mediates the pH‐Driven Structure and Activity of the Enzyme and Photosynthesis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT In Arabidopsis, exposure to microbial volatile compounds promotes thiol reduction of the Cys95 residue of the photosynthetic enzyme fructose‐1,6‐bisphosphatase (cFBP1). Although highly conserved in plants, the Cys95 function still remains unknown. We characterised recombinant wild‐type (WT) cFBP1 and a variant (C95S) in which the Cys95 residue

Assessing the exercise‐related kinetics of circulating cell‐free DNA, circulating tumour DNA, DNase I activity and cytokines in patients with solid tumours: A pilot study

open access: yesExperimental Physiology, EarlyView.
Abstract Circulating cell‐free DNA (cfDNA), circulating tumour DNA (ctDNA) and inflammatory cytokines have prognostic and predictive value in oncology. However, the effects of acute exercise on cfDNA levels are unknown. Here, we explore the kinetics of cfDNA, ctDNA and cytokines upon an incremental exercise test in a pilot cohort of cancer patients ...

Oxidative and O2 diffusive function in triceps brachii of recreational to world class swimmers

open access: yesExperimental Physiology, EarlyView.
Abstract This study aimed to evaluate in vivo oxidative capacity and relative resistance to O2 diffusion using near‐infrared spectroscopy (NIRS) in the m. triceps brachii of recreational to world class swimmers and evaluate their relationships with swimming performance.

Diffusion and physical constraints limit oxidative capacity, capillary supply and size of muscle fibres in mice and humans

open access: yesExperimental Physiology, EarlyView.
Abstract It has been suggested that angiogenesis during skeletal muscle fibre hypertrophy allows escape from the ‘size constraint’, which is the inverse relationship between oxidative capacity and muscle fibre cross‐sectional area (FCSA). It is, however, not known whether there are any limitations to the combinations of FCSA, oxidative capacity 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 ...

Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds

open access: yesExperimental Physiology, EarlyView.
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal

The repair capacity spectrum of human skeletal muscle injury from sports to surgical trauma settings

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The interplay between current knowledge, treatment strategies and remaining unsolved clinical challenges in optimising clinical outcomes for patients suffering skeletal muscle tissue injury. In particular the outcome for strain injuries and acute extremity compartment syndrome remains poor, despite extensive work in animal models.
