Dwelling in prolonged grief: Resting state functional connectivity during oxytocin and placebo administration

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 245-257, January 2023., 2023
In older adults who experienced the death of a partner, higher prolonged grief symptoms were associated with less anticorrelation between retrosplenial default network and cingulo‐opercular networks during resting state, and more dwell time in a dynamic functional connectivity state involving positive correlations between large‐scale brain networks ...

Total Synthesis of Dactyloquinone A and Spiroetherone A via a Metal‐Hydride Hydrogen Atom Transfer (MHAT) Process and a Quinol–Enedione Rearrangement

open access: yesAngewandte Chemie International Edition, Accepted Article.
We report the total synthesis of dactyloquinone A and spiroetherone A from a meroterpenoid scaffold obtained by the deconjugative alkylation of a Wieland–Miescher type ketone. For dactyloquinone A, we employed an intramolecular hydrofunctionalisation of the internal trisubstituted alkene with a quinone monoacetal via a metal‐hydride hydrogen atom ...

Generalized models for quantifying laterality using functional transcranial Doppler ultrasound

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 35-48, January 2023., 2023
Transcranial functional Doppler Ultrasound has been used to assess brain lateralization, but the methods used to extract a laterality index (LI) have involved simple averaging over a period of interest. Here, we compare results from that method with results from a generalized linear models (GLM) approach similar to that used in functional magnetic ...

A Novel 3D‐Printed Microfluidic Bioreactor With Electrospun Scaffold Integration as a Platform for Cardiovascular Tissue Engineering

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Cardiovascular diseases are one of the leading causes of global mortality. Treatment methods such as bypass graft operations, while often successful, can fail in cases of systemic disease or compliance mismatch. Tissue engineered vascular grafts may offer a potential solution, by means of an implantable cell‐seeded scaffold that can integrate ...

Charting the landscape of the environmental exposome

open access: yesiMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push
