Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Dynamic Performance of a 3D Re-entrant Structure

, 2020
In this study, the mechanical performance of a three-dimensional (3D) re-entrant structure subjected to dynamic compression was experimentally investigated using a high-speed Instron machine. Quasi-static tests were conducted for comparison.

Identifying potential re-entrant circuit locations from atrial fibre maps. [PDF]

, 2019
Re-entrant circuits have been identified as potential drivers of atrial fibrillation (AF). In this paper, we develop a novel computational framework for finding the locations of re-entrant circuits from high resolution fibre orientation data.

Enhanced mechanical performance of re-entrant structures using carbon fiber/polyamide composites by dual-material 3D printing

Journal of Materials Research and Technology
Multi-component 3D printing has become a reliable and feasible strategy with complex shape and colorful appearance. However, the overall mechanical performance is greatly dependent on the material components and printing pattern design.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Re-entrant ferromagnet PrMn2Ge0.8Si1.2: Magnetocaloric effect

, 2009
The structural and magnetic properties of the re-entrant ferromagnet PrMn2Ge0.8Si1.2 have been investigated by various experimental methods. Similar to the canonical re-entrant ferromagnet SmMn2Ge2, multiple magnetic phase transitions have been detected ...
