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.

Report of a Novel Bilateral Variation of Sciatic and Inferior Gluteal Nerve: A Case Study

Basic and Clinical Neuroscience, 2021
Introduction: The sciatic nerve is the thickest nerve of the sacral plexus which innervates many muscles and vast areas of the skin of the lower limb. It leaves the pelvis via the greater sciatic foramen, emerges into the gluteal region by passing under ...

Endoscopic Curettage of Bone Cyst of the Fibular Head

Arthroscopy Techniques, 2017
Open resection of cystic or other benign intramedullary lesions of the fibular head and neck requires dissection and mobilization of the common peroneal nerve.

Common peroneal nerve palsy from an untreated popliteal pseudoaneurysm after penetrating injury [PDF]

, 2007
A 17-year-old boy presented with drop foot and loss of extension in his left knee after penetrating injury to the popliteal region. Color duplex ultrasonography and angiography revealed a popliteal artery pseudoaneurysm in the popliteal fossa ...

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 ...

Anatomic division and safe areas of common peroneal nerve around the fibular head

Acta Orthopaedica et Traumatologica Turcica, 2021
Twenty eight knees of the 14 cadevers were dissected to determine course of the common peroneal nerve from its origin to its termination.Particular dissection was performed to defining: 1. its relationship to fibular head, 2. its branches relationship to

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 ...

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.

Restoration of neuromuscular function by mitochondrial transplantation in injured mouse skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Mice received chemical injury (cardiotoxin) in the tibialis anterior muscle of one limb, and the contralateral muscle was injected with phosphate‐buffered saline (PBS) as a sham control. Mice then received PBS or mitochondria suspended in PBS into the tail vein.
