White Matter Microstructure Alterations in Older Adults With Dyslipidemia Associated With Cognitive and Locomotor Dysfunction Evaluated Using Neurite Orientation Dispersion and Density Imaging

Brain and Behavior, Volume 15, Issue 6, June 2025.
This study used NODDI to identify white matter microstructure alterations in older adults with dyslipidemia, revealing significantly reduced neurite density in several brain regions. These reductions were linked to declines in cognitive and motor functions, suggesting that NODDI may serve as a biomarker for dyslipidemia‐related axonal degeneration ...

Docosahexaenoic Acid and Nervonic Acid Synergically Enhance Cognitive Memory in Normal Mice via Brain Fatty Acids Remodeling

eFood, Volume 6, Issue 3, June 2025.
1. DHA and NA can enhance memory by increasing their levels in gray and white matter. 2. DHA and NA can enhance memory by increasing their levels in gray and white matter. 3. DHA and NA combination regulate spatial memory in a dose‐specific manner. ABSTRACT Docosahexaenoic acid (DHA) and nervonic acid (NA) are the main components of brain gray and ...

The Fragile X Messenger Ribonucleoprotein 1 Regulates the Morphology and Maturation of Human and Rat Oligodendrocytes

Glia, Volume 73, Issue 6, Page 1203-1220, June 2025.
Main Points Loss of FMRP impairs human and rat oligodendrocyte (OL) morphology in vitro. FMRP‐deficient OLs show impaired maturation when engrafted in hypomyelinated mice. Rat Fmr1 knockout OLs show a delay in myelin sheath formation in vivo. ABSTRACT The Fragile X Messenger Ribonucleoprotein (FMRP) is an RNA binding protein that regulates the ...

The Role of Proton Magnetic Resonance Spectroscopy in Neonatal and Fetal Brain Research

Journal of Magnetic Resonance Imaging, Volume 61, Issue 6, Page 2404-2424, June 2025.
The biochemical composition and structure of the brain are in a rapid change during the exuberant stage of fetal and neonatal development. 1H‐MRS is a noninvasive tool that can evaluate brain metabolites in healthy fetuses and infants as well as those with neurological diseases.

Considerations and recommendations from the ISMRM diffusion study group for preclinical diffusion MRI: Part 1: In vivo small‐animal imaging

Magnetic Resonance in Medicine, Volume 93, Issue 6, Page 2507-2534, June 2025.
Abstract Small‐animal diffusion MRI (dMRI) has been used for methodological development and validation, characterizing the biological basis of diffusion phenomena, and comparative anatomy. The steps from animal setup and monitoring, to acquisition, analysis, and interpretation are complex, with many decisions that may ultimately affect what questions ...

Diffusion tensor subspace imaging of double diffusion–encoded MRI delineates small fibers and gray‐matter microstructure not visible with single encoding techniques

Magnetic Resonance in Medicine, Volume 93, Issue 6, Page 2370-2385, June 2025.
Abstract Purpose Double diffusion encoding (DDE) acquisition strategies promise specificity for small‐dimensional structures inaccessible to single diffusion encoding (SDE). For DDE‐weighted MRI scans to become relevant for whole brain imaging, signal reconstruction frameworks must accurately report microstructural features of interest—especially ...

Sensory Nerve Action Potential Analysis in a Cohort of Patients With Spinal Muscular Atrophy Aged 12 Years and Older

Muscle &Nerve, Volume 71, Issue 6, Page 1016-1024, June 2025.
ABSTRACT Introduction/Aims Survival Motor Neuron 1 (SMN1)‐related spinal muscular atrophy (SMA) is characterized by α‐motor neuron degeneration, with sensory function assumed to be clinically preserved. However, recent studies in severely affected patients and animal models have challenged this view.
