Mesoscale Whole‐Brain T2*‐Weighted and Associated Quantitative MRI in Humans at 10.5 T

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 817-825, August 2026.
ABSTRACT Purpose To demonstrate mesoscale whole‐brain T2*‐weighted (T2*w) MRI at 10.5 T, quantify R2* relaxation rate and magnetic susceptibility (χ), and evaluate T2*w contrast at such high field strength. Methods Multi‐echo GRE (ME‐GRE) data were collected in healthy adults at 0.5 mm isotropic resolution at 10.5 T.

Quantitative Diffusion and T2 Mapping Using RF‐Modulated Phase‐Based Gradient Echo Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 49-65, July 2026.
ABSTRACT Purpose To introduce and evaluate the feasibility of a novel RF‐phase modulated gradient echo (GRE) method for quantitative diffusion MRI, aimed at mitigating geometric distortion and enabling high‐resolution 3D quantitative diffusion/T2 mapping as a complementary alternative to conventional DWI.

Quantitative Susceptibility Mapping of Deep Grey Matter in MS: Association With Clinical Scores and Brain Volume Measures

Brain and Behavior
Background Changes in quantitative susceptibility mapping (QSM) of the deep grey matter (DGM) in multiple sclerosis (MS) are thought to reflect tissue damage invisible in conventional magnetic resonance imaging (MRI) sequences, such as iron‐related ...

Sustainability Reporting in Higher Education: A Systematic Review and Bibliometric Analysis for Strategic Decision‐Making

Business Ethics, the Environment &Responsibility, Volume 35, Issue 3, Page 2512-2529, July 2026.
ABSTRACT The communication of sustainable development is essential for higher education institutions (HEIs), which voluntarily prepare sustainability reports (SRs) to demonstrate commitment and inform strategic decision‐making. This study conducts a systematic literature review (SLR) to identify and analyze the challenges associated with implementing ...

Microbial Metabolite‐Stimulated Bitter Taste Receptor T2R14 Signaling Is Modulated by CFTR Interactions

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
Bitter taste receptors (T2Rs) play an important role in physiological and cellular responses. Bitter tasting chemicals and microbial metabolites can bind to T2R14, which enables interactions between T2R14 and specific intracellular domains of the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel.

An Innovative Strategy to Enhance Polyphenol Content and Quality Traits of Olive Oil and Valorization of Mill Wastewater

eFood, Volume 7, Issue 3, June 2026.
The new technique, by exploiting and modifying the partition coefficients of various molecules in immiscible solvents, makes it possible to obtain olive oils rich in polyphenols with outstanding characteristics. Moreover, the extension of this technique allows the transfer of polyphenols present in vegetation water into any lipid matrix, such as seed ...

Assessment of Optimal T1/T2‐Weighted Combinations for Myelin Sensitivity: Effects of Echo Time and Exponents

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3176-3186, June 2026.
ABSTRACT Purpose The aim of this study is to improve the traditional T1‐weighted (T1w) over T2‐weighted (T2w) ratio as a proxy for myelin by investigating the optimal T2w TE and combination of exponent‐weighted T1w and T2w images (T1wx1/T2wx2). Methods T1w and T2w Gradient And Spin Echo (GRASE) data were acquired from 14 volunteers, 6 of whom had a ...

Reducing Noise Induced by Cardiac Pulsatility in Brain Maps of R2* and Magnetic Susceptibility Using Tailored k‐space Sampling

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
With linear k‐space sampling trajectories, cardiac pulsation leads to MRI signal instabilities that increase the variability (standard deviation, SD) of R2* and QSM maps across repetitions. Here, we propose alternative trajectories that aim to mitigate the impact of cardiac‐induced noise in brain maps of R2* and QSM.
