Comparison of Single‐Breath and Multi‐Breath Xe‐MRI in the Longitudinal Assessment of Treatment in Children With Cystic Fibrosis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Elexacaftor/tezacaftor/ivacaftor (ETI) is a current standard therapy for pediatric cystic fibrosis (CF). Multiple‐breath washout 129Xe MRI (MBW Xe‐MRI) is improved following 1 month of treatment. However, the utility of MBW Xe‐MRI over extended ETI treatment and its comparison to single‐breath Xe‐MRI and pulmonary function tests ...

Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Are physiological oscillations physiological?

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Benchmarking Hybrid CNN‐Transformer Versus Pure Transformer Architectures for Accelerated Hyperpolarized 129Xe MRI Reconstruction

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Hyperpolarized 129Xe MRI faces technical challenges including low signal‐to‐noise ratio and breath‐hold constraints. Current literature focuses on proprietary deep learning methods or image‐domain enhancements. Purpose To present a comprehensive evaluation of transformer and hybrid CNN‐transformer architectures integrating dual ...

Efficacy of omega‐3 fatty acids as a functional food: a multifaceted approach to health reinforcement

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Omega‐3 fatty acids (omega‐3s) are polyunsaturated fatty acids linked with numerous health benefits. Omega‐3s exhibit multifaceted activities through various mechanisms. Eicosapentaenoic acid (EPA) alleviates oxidative stress by lowering reactive oxygen species and improving oxidative stress in brain tissues and acts against neurodegenerative ...

MRI for Mixing Quality in Microfluidics

Magnetic Resonance in Chemistry, EarlyView.
Fluidic mixing in a micromixer: Paramagnetic relaxation enhancement and chemical shift differences were explored to reveal mixing quality at the small dimensions of an optically opaque y‐mixer. ABSTRACT Liquid state processes often involve mixing of process streams.

Physiological Interpretation of the Lactate to Pyruvate AUC Ratio for Hyperpolarized [1‐13C]‐Pyruvate Studies

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To explore the relationship between potentially rate‐limiting steps in lactate production and the lactate area‐under‐the‐curve (AUC) to pyruvate AUC ratio for analysis of hyperpolarized (HP) [1‐13C]‐pyruvate data. Theory and Methods Simplifying assumptions are introduced to a pharmacokinetic (PK) model with three physical compartments ...

Optimized Detection of Left Ventricular Hyperpolarized [1‐13C]Pyruvate Signal in Human Cardiac Metabolic Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to improve the analysis of the left ventricular (LV) blood pool hyperpolarized [1‐13C]pyruvate signal for a more reliable quantification of downstream metabolic outcome. Methods Hyperpolarized [1‐13C]pyruvate magnetic resonance spectroscopic images were acquired dynamically at 3 Tesla in 106 participants (NCT03685175).

Free‐Breathing Magnetization Transfer Imaging of the Lung at 0.55 T Using bSTAR

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a clinically applicable method for magnetization transfer (MT) imaging of the lung at 0.55 T. Methods MT imaging of the chest was explored in healthy volunteers at 0.55 T using a self‐gated 3D half‐radial dual‐echo balanced steady‐state free precession sequence (bSTAR), a 2D multi‐slice gradient echo method (GRE) acquired in
