Recovery of neurophysiological measures in post-COVID fatigue: a 12-month longitudinal follow-up study.

One of the major consequences of the COVID-19 pandemic has been the significant incidence of persistent fatigue following resolution of an acute infection (i.e. post-COVID fatigue).

Neural dysregulation in post-COVID fatigue.

Following infection with SARS-CoV-2, a substantial minority of people develop lingering after-effects known as 'long COVID'. Fatigue is a common complaint with a substantial impact on daily life, but the neural mechanisms behind post-COVID fatigue remain unclear. We recruited 37 volunteers with self-reported fatigue after a mild COVID infection and carried out a battery of behavioural and neurophysiological tests assessing the central, peripheral and autonomic nervous systems.

2.6 A resolution crystal structure of helices of the motile major sperm protein (MSP) of Caenorhabditis elegans.

The amoeboid locomotion of nematode sperm is mediated by the assembly dynamics of the major sperm protein (MSP). MSP forms fibrous networks based on a hierarchy of macromolecular assemblies: helical subfilaments are built from MSP dimers; filaments are formed from two subfilaments coiling round one another; and filaments themselves supercoil to produce bundles. To provide a structural context for understanding the role of these macromolecular assemblies in cell locomotion, we have determined the 2.
