A Comparison of Children’s Fitness in the Northwest and Southwest of England [PDF]
, 2014 The data from this paper was gathered from a larger cross-sectional study examining children’s physical activity participation in the Northwest and the Southwest of England. The purpose of this study was to carry out a battery of health and fitness tests

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Experimental Gerontology, 2023 Neuronal hyperactivity is a key abnormality in early stage Alzheimer's disease (AD). Medial entorhinal cortex (mEC) plays a vital role in memory function and is affected early in AD.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Pacific Journal of Mathematics, 1986 A Fitting structure is an ordered 5-tuple (H,S,\(\phi\),\(\psi\),\(\sigma)\) where H is a semigroup, S is a ring, \(\phi\) is a homomorphism of H into the multiplicative semigroup of all left S-module homomorphisms of the left regular S-module, \(\psi\) is an antihomomorphism of H into the multiplicative semigroup of all right S-module homomorphisms of

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Exaptation and emergence as mechanisms to cross fitness valleys during evolution: an example using simulated homing behaviour [PDF]
, 2008 Evolution is often considered a gradual hill climbing process, slowly increasing the fitness of organisms. I investigate the evolution of homing behaviour in simulated intertidal limpets.
