Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Conditional Randomization Tests for the Specification of Interference Structure

Journal of Applied Econometrics, Volume 41, Issue 6, Page 791-805, September/October 2026.
ABSTRACT This study proposes specification tests for interference structure in causal inference with spillovers. We focus on experimental settings in which the treatment assignment mechanism is known. To test whether a given exposure mapping adequately summarizes the true interference structure, we develop conditional randomization tests by utilizing ...

The EUROmediCAT Network and Databases: A Resource for Pharmacovigilance in Pregnancy

Pharmacoepidemiology and Drug Safety, Volume 35, Issue 5, May 2026.
ABSTRACT Background The evidence gap relating to the risk of congenital anomalies (CA) associated with first trimester medication exposure in pregnancy is well recognized. Aims We describe the EUROmediCAT network and databases, and the methodological approach to pregnancy pharmacovigilance.
