Induced Circular Dichroism From the Binding of Achiral Bivalent Ligands to Transthyretin

Journal of Molecular Recognition, Volume 39, Issue 3, May 2026.
ABSTRACT Achiral bivalent ligands capable of simultaneous occupation of both hormone binding sites of transthyretin generate a substantial and complex induced near ultraviolet circular dichroism spectrum during protein binding, revealing the dynamics of this process.

The Effect of the Anticonvulsant Topiramate on Acetylcholine‐Induced Calcium Signals is Linked to Sirt‐1 Activity

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
This work provides a potential new link between the anticonvulsive Topiramate, the deacetylase Sirt‐1 and the cholinergic signalling, suggesting that Topiramate may modulate cholinergic pathways in a Sirt‐1 depended manner. ABSTRACT Although some forms of epilepsy directly result from mutations in nicotinic acetylcholine receptors, none of the ...

Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production

Journal of Applied Polymer Science, Volume 143, Issue 13, April 5, 2026.
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.

Fine‐Scale Segmentation and Spatiotemporal Variability of the 2010 Mw 8.8 Maule Aftershock Sequence Revealed by a Deep‐Learning‐Based Earthquake Catalog

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We re‐examine the aftershock sequence of the Mw 8.8 Maule earthquake in south‐central Chile to understand how seismicity, magnitude‐frequency distribution, and fault structure vary along the rupture zone. Using the International Maule Aftershock Deployment (IMAD) data set, we analyze 10 months of continuous data from approximately 156 ...
