Online Drift Compensation for Chemical Sensors Using Estimation Theory [PDF]

, 2010
Sensor drift from slowly changing environmental conditions and other instabilities can greatly degrade a chemical sensor\u27s performance, resulting in poor identification and analyte quantification.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

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+.

Unravelling the monomer molar ratio modulation of the optoelectronics of Poly(propylene imine) tetra(thiophen-2-ylmethylene-amine)-co-poly(3-hexylthiophene-2,5-diyl) copolymer

Journal of Science: Advanced Materials and Devices
Tuning the molecular structure of a copolymer is of considerable importance for optimizing its optoelectronic and morphological properties. This will enormously help in improving and understanding the performance of a copolymer as a donor material in ...

Behenic Acid Monolayer and Bilayer Assemblies- A Study of Concanavalin A (Con A) Adsorption and its Interaction with Dextran Using Surface Plasmon Resonance Spectroscopy and Microscopy [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1993
Deposition of behenic acid (B.A) mono and bilayers onto gold coated surfaces was performed by Langmuir-Blodget dip-casting technique. Surface Plasmon resonance (SPR) and ellipsometry methods were employed for investigation of the monolayer and bilayer ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Non-Invasive Assessment of Skin Barrier Properties: Investigating Emerging Tools for In Vitro and In Vivo Applications

Cosmetics, 2017
There is increasing interest in the development of non-invasive tools for studying the properties of skin, due to the potential for non-destructive sampling, reduced ethical concerns and the potential comparability of results in vivo and in vitro.

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.
