Nanoparticle Immunoadjuvant Complexes Augment Germinal Center Responses to Vaccination

open access: yesAdvanced Science, EarlyView.
Scaffolding IL‐21 on the surface of a self‐assembling nanoparticle immunogen drives improved germinal center and humoral immune responses. These nanoparticle immunoadjuvant complexes (NICs) functionally modulate the germinal center driving improved somatic hypermutation and antibody maturation, suggesting this platform has potential utility as a ...

Atomic Scale Ordering of Liquid Water at a Dynamic Pt(111) Interface Under Electrochemical Conditions Imaged by Electron Holography

open access: yesAdvanced Energy Materials, EarlyView.
High resolution electron holography was used to image the projected electric potential of ordered water layers at the interface to a platinum (111) electrode. The observed reorganization of the water layers upon applying external potentials suggests that the electric potential drop of the electric double layer is mainly carried by the polarization ...

Clock gene dysregulation in epilepsy: A systematic review

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.
