Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS 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.

A Fine Analysis of Zn Species Structure and Distribution in Zn/ZSM-5 Catalysts by Linear Combination Fitting Analysis of XANES Spectra

open access: yesMolecules
Investigating the distribution of different Zn species on Zn-containing zeolite catalysts is crucial for identifying the active sites and establishing the relationship between the catalyst’s structure and its activity in the process of ethylene ...

Effect of buoyancy on fingering growth activity in immiscible two-phase flow displacements

open access: yesJournal of Fluid Science and Technology, 2018
Immiscible displacement processes have been investigated for decades to understand their applications, such as geosequestration of CO2 and enhanced oil recovery, in detail.

A multi-resolution model to capture both global fluctuations of an enzyme and molecular recognition in the ligand-binding site

open access: yes, 2016
In multi-resolution simulations, different system components are simultaneously modelled at different levels of resolution, these being smoothly coupled together.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

The Keasler site (41HS235), a Titus Phase Cemetery in the Little Cypress Creek Basin, Harrison County, Texas [PDF]

open access: yes, 2015
The Keasler site (41HS235) is a Late Caddo period, Titus phase (ca. A.D. 1430-1680) cemetery in the East Texas Pineywoods. The site was excavated by collectors in the late 1970s, including Red McFarland, one of the more active looters of Caddo burials in

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS 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 ...

Asp-120 Locates Zn2 for Optimal Metallo-β-lactamase Activity [PDF]

open access: yes, 2007
Metallo-β-lactamases are zinc-dependent hydrolases that inactivate β-lactam antibiotics, rendering bacteria resistant to them. Asp-120 is fully conserved in all metallo-β-lactamases and is central to catalysis.
