Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

In Situ pH Determination Using 1H‐MRS Acetate Chemical Shift for Noninvasive Postmortem Examinations

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
The chemical‐shift difference between acetate and myo‐inositol measured by MRS enables estimation of pH in the acidic range. Noninvasive pH assessment in forensic investigations is demonstrated in 58 cases and validated by measurements in extracted tissue.

Dipolar Order Mapping Based on Spin‐Lock Magnetic Resonance Imaging

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
To quantify the dipolar order relaxation time T1D$$ {T}_{1D} $$ using spin‐lock MRI technique, we introduce a T1D$$ {T}_{1D} $$‐specific ratio, denoted as RATIOdosl$$ {RATIO}_{dosl} $$. A novel rotary‐echo spin‐lock sequence was developed to enable dual‐frequency spin‐lock acquisition.

Using large language models to automate herbarium specimen transcription: A case study at the Missouri Botanical Garden

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1068-1075, July 2026.
Biological specimens housed in natural history collections are indispensable resources for documenting where species occur and how they have changed through time, and are thus vital for combating biodiversity loss. Digitization of these collections promises to make these critical resources globally available.

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...
