The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

The influence of directors’ and officers’ liability insurance on management tone manipulation – evidence from China

China Accounting and Finance Review
This paper explores the association between directors’ and officers’ liability insurance (D&O insurance) and management tone manipulation. This study uses data from A-share listed non-financial companies from 2009 to 2021 as its sample for empirical ...

Nonlinear Dynamics of the Perceived Pitch of Complex Sounds [PDF]

, 1999
We apply results from nonlinear dynamics to an old problem in acoustical physics: the mechanism of the perception of the pitch of sounds, especially the sounds known as complex tones that are important for music and speech ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

The effects of language dominance on the L1 and L2 tone production of Mandarin–Cantonese bilinguals [PDF]

JASA Express Letters
The present study investigated the effects of language dominance on the cross-linguistic influence in the first and second languages (L1 and L2) of lexical tone production by Mandarin–Cantonese late bilinguals.

All's well that ends well [PDF]

, 2010
A few years ago, Jasanoff adopted the central tenet of my accentological theory, viz. that the Balto-Slavic acute was a stød or glottal stop, not a rising tone (cf. Kortlandt 1975, 1977, 2004, Jasanoff 2004a).

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

On Establishing Underlying Tonal Contrast [PDF]

, 2014
Phonological field work is largely about establishing contrast in comparable environments. The notion of phonological contrast, however, can be confusing, particularly in its application to tone analysis.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
