Non‐Contrast Assessment of Blood–Brain Barrier Permeability to Water: Improved Signal Modeling and Data Acquisition

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Water‐extraction‐with‐phase‐contrast‐arterial‐spin‐tagging (WEPCAST) MRI is a non‐contrast method to estimate the blood–brain barrier (BBB) permeability to water. Similar to other arterial‐spin‐labeling (ASL) based techniques, signal‐to‐noise ratio is a limitation.

Modeling the Intermediate Flow Regime in Flow‐Compensated Intravoxel Incoherent Motion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The intravoxel incoherent motion (IVIM) model is commonly used to separate the effects of motion related to diffusion and blood microcirculation (perfusion) on the MR signal. Depending on the encoding time (T), it is possible to probe the different temporal regimes of blood motion, which resemble a ballistic flow at short T and a ...

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

open access: yesOikos, EarlyView.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Introduction Neonates undergoing cardiac surgery face a high risk of neurological injury and neurodevelopmental complications. Transcranial Doppler monitoring is used and validated in adults to measure cerebral blood flow and can provide valuable insights into cerebral perfusion in neonates.
