Energy Metabolism in Mouse Sciatic Nerve A Fibres during Increased Energy Demand (2022)
Journal Article
Rich, L. R., Ransom, B. R., & Brown, A. M. (2022). Energy Metabolism in Mouse Sciatic Nerve A Fibres during Increased Energy Demand. Metabolites, 12(6), Article 505. https://doi.org/10.3390/metabo12060505

The ability of sciatic nerve A fibres to conduct action potentials relies on an adequate supply of energy substrate, usually glucose, to maintain necessary ion gradients. Under our ex vivo experimental conditions, the absence of exogenously applied g... Read More about Energy Metabolism in Mouse Sciatic Nerve A Fibres during Increased Energy Demand.

© 2020, The Author(s). Despite several compounds entering clinical trials for the negative and cognitive symptoms of schizophrenia, few have progressed beyond phase III. This is partly attributed to a need for improved preclinical models, to understa...

The stimulus evoked compound action potential, recorded from ex vivo nerve trunks such as the rodent optic and sciatic nerve, is a popular model system used to study aspects of nervous system metabolism. This includes (1) the role of glycogen in supp... Read More about A method for reducing animal use whilst maintaining statistical power in electrophysiological recordings from rodent nerves.

Hypothermic neuroprotection during reperfusion following exposure to aglycemia in central white matter is mediated by acidification (2019)
Journal Article

Hypoglycemia is a common iatrogenic consequence of type 1 diabetes therapy that can lead to central nervous system injury and even death if untreated. In the absence of clinically effective neuroprotective drugs we sought to quantify the putative neu...

The stimulus evoked compound action potential (CAP), recorded using suction electrodes, provides an index of the relative number of conducting axons within a nerve trunk. As such the CAP has been used to elucidate the diverse mechanisms of injury res... Read More about Fibre sub-type specific conduction reveals metabolic function in mouse sciatic nerve.

Acute effect of pore-forming Clostridium perfringens ?-toxin on compound action potentials of optic nerve of mouse (2017)
Journal Article
Cases, M., Brown, A., Llobet, A., Terni, B., Gómez de Aranda, I., Blanch, M., …Solsona, C. (2017).

ε-Toxin is a pore forming toxin produced by Clostridium perfringens types B and D. It is synthesized as a less active prototoxin form that becomes fully active upon proteolytic activation. The toxin produces highly lethal enterotoxaemia in ruminants,... Read More about Acute effect of pore-forming Clostridium perfringens ?-toxin on compound action potentials of optic nerve of mouse.
