Effect of Water Suppression and Metabolite Cycling on Quantification of 1H MRS Spectra in the Human Brain at 3 Tesla

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study investigates the effect of VAPOR water suppression and metabolite cycling on metabolite quantification and macromolecules in proton magnetic resonance spectroscopy. Methods Single‐voxel semi‐LASER spectra (TR/TE = 3000/28 ms) and metabolite‐nulled spectra (macromolecules) were acquired in five healthy subjects in the ...

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

GABA+‐Edited Magnetic Resonance Spectroscopy Deep Learning Quality Assessment Framework

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Motivated by the need to improve GABA+‐edited magnetic resonance spectroscopy (MRS) quality, we developed a three‐module framework to improve transient averaging based on quality. We hypothesized that training a deep learning (DL) model to differentiate spectrum quality could improve transient averaging compared to traditional ...

G Protein‐Coupled Receptor 17 (Gpr17) Enhances Leptin and Insulin Sensitivity in Lean and Obese Mouse Models

open access: yesObesity, EarlyView.
This study identifies G protein‐coupled receptor 17 (Gpr17) as a novel regulator of leptin and insulin sensitivity. Using complementary knockout models, we demonstrate that Gpr17 deletion enhances energy expenditure, restores leptin responsiveness, and improves insulin sensitivity, revealing Gpr17 as a potential therapeutic GPCR target for obesity and ...

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them

open access: yesPeople and Nature, EarlyView.
Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...
