Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Remote Cell Growth Sensing Using Self-Sustained Bio-Oscillations [PDF]

, 2018
A smart sensor system for cell culture real-time supervision is proposed, allowing for a significant reduction in human effort applied to this type of assay. The approach converts the cell culture under test into a suitable “biological” oscillator.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A Sensor Interface for Neurochemical Signal Acquisition [PDF]

2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019
This paper describes the design of an integrated sensor interface for neurochemical signal acquisition. Neurochemicals undergo oxidation and reduction reactions in the presence of an action potential. Thus, knowledge of the oxidation and reduction potentials of neurochemicals is important in the neurostimulation treatment of neurological and ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Second language acquisition at the interfaces

Lingua, 2011
Abstract In recent research on L2 acquisition, there has been considerable emphasis on interfaces between the linguistic system and grammar external components, such as syntax/discourse, or between different modules of grammar, such as syntax/semantics, syntax/morphology or morphology/phonology. This has led to proposals that difficulties experienced
