Age‐related loss of hysteresis in the spontaneous vascular sympathetic baroreflex is associated with altered neural rather than mechanical control

Experimental Physiology, EarlyView.
Abstract The vascular sympathetic baroreflex is critical for stabilising blood pressure. A notable feature of this reflex is hysteresis, a directional asymmetry in responsiveness during rising versus falling pressure that is evident in young adults but attenuated in older age.

Common peroneal nerve dysfunction after high tibial osteotomy

, 1990
We assessed 16 patients before and after high tibial osteotomy by electrophysiological recordings, creatine phosphokinase levels, radiographs and intracompartmental pressure monitoring. We found mild electrophysiological abnormalities pre-operatively in

Running‐based rehabilitation does not improve muscle function after volumetric muscle loss despite improving hindlimb weight‐bearing asymmetry in mice

Experimental Physiology, EarlyView.
Abstract Volumetric muscle loss (VML) is a traumatic skeletal muscle injury characterized by chronic functional impairments in the affected muscle and adjacent uninjured bone. Rehabilitative strategies aimed at restoring limb function following VML, including voluntary running, have shown limited efficacy and in some cases have been detrimental.

Entrapment of the superficial peroneal nerve. Three case reports

, 1985
Entrapment of the superficial peroneal nerve is an unusual cause of pain in the ankle and foot. In such cases decompression of the nerve at the point of exit from the deep fascia will produce a good result. Three cases are described.

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

The Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

Immediate Nerve Transfer for the Treatment of Peroneal Nerve Palsy Secondary to an Intraneural Ganglion: Case Report and Review

, 2017
Intraneural ganglion cysts that occur within the common peroneal nerve are a rare cause of foot drop. The current standard of treatment for intraneural ganglion cysts involving the common peroneal nerve involves (1) cyst decompression and (2) ligation ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Trafficking and potentiation of Nav1.7 and Nav1.8 channels are mediated by IQGAP1

The Journal of Physiology, EarlyView.
Abstract figure legend IQGAP1 binds to the voltage‐gated Nav1.7 and Nav1.8 channels and TRPA1 channels in sensory neurons. Inflammatory mediators (IM), including PGE2 and TNFα, released during nerve injury and inflammation activate intracellular signalling messengers such as PKA, p38 MAPK and Cdc42 through their respective receptors.

Acute peroneal compartmental syndrome: report of a case

, 1985
Among the compartmental syndromes the necrosis of peroneal muscles is unusual. We report a case in which the swelling of peroneal muscle causes a compression of the common peroneal nerve below the peroneal head.
