Angiogenic Potential of Small Extracellular Vesicles Produced by Stimulated Mesenchymal Stromal Cells Under Hypoxic Conditions

open access: yesJournal of Extracellular Biology, Volume 5, Issue 1, January 2026.
ABSTRACT Regenerative vascular medicine research has positioned mesenchymal stromal cells (MSCs) as a leading candidate to treat ischemic diseases. Recent studies have highlighted the emerging role of small extracellular vesicles (sEVs) produced by MSCs in their own potential.

Convolutional recurrent U‐net for cardiac cine MRI reconstruction via effective spatio‐temporal feature exploitation

open access: yesMedical Physics, Volume 53, Issue 1, January 2026.
Abstract Background Cardiac Cine Magnetic Resonance Imaging (MRI) provides dynamic visualization of the heart's structure and function but is hindered by slow acquisition, requiring repeated breath‐holds that challenge sick patients. Accelerated imaging can mitigate these issues but potentially reduce spatial and temporal resolution.

Flow‐suppressed 2D spin‐echo imaging with high tolerance to B1 inhomogeneity using hyperbolic secant pulses

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 172-187, January 2026.
Abstract Purpose To demonstrate flow‐suppressed two‐dimensional (2D) spin‐echo and spin‐echo diffusion echo‐planar imaging (EPI) sequences using hyperbolic secant (HS) pulses for both π/2 excitation and π refocusing. Theory and Methods A theoretical framework to derive phase dispersion of moving spins under π/2 excitation and π refocusing using HS ...

Importance of R2 accuracy in susceptibility source separation

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 157-171, January 2026.
Abstract Purpose To examine the importance of R2 accuracy on independent paramagnetic and diamagnetic outputs from susceptibility source separation in the brain from two publicly available methods. Methods The effects of R2 errors, which translate into R2′$$ {\mathrm{R}}_2^{\prime } $$ errors, on output maps from χ‐separation and χ‐sepnet were examined
