Frozen in Place: Proximity Labeling Maps Glial Interactomes Across Cell States

open access: yesGlia, Volume 74, Issue 10, October 2026.
Proximity labeling enables cell‐type‐specific and spatially resolved mapping of glial protein networks. Proximity labeling approaches provide insights into glial function under physiological and pathological conditions. ABSTRACT Glial cells, including radial glia, oligodendrocyte precursor cells (OPCs), oligodendrocytes, astrocytes, and microglia, are ...

Morpho‐Anatomical and HPTLC Investigations of Lysimachia nummularia L. (Primulaceae) Grown in Switzerland

open access: yesMicroscopy Research and Technique, Volume 89, Issue 10, Page 1230-1243, October 2026.
This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

Evaluation of Phantom Doping Materials in Quantitative Susceptibility Mapping

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1545-1556, October 2026.
ABSTRACT Purpose To measure magnetic susceptibility (χ) with Quantitative Susceptibility Mapping (QSM) and evaluate its repeatability using four phantom doping materials relevant to QSM applications. Methods A cylindrical phantom was constructed containing vials of agarose gel doped with two paramagnetic materials (ferritin, USPIO) and two diamagnetic ...

The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Time‐Dependent Single Diffusion Encoding MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Geometric exchange between dendritic spines and shafts is often neglected, yet it exhibits the same signature as permeative exchange, biasing NEXI/SMEX measurements. We propose two models: an extended three‐compartment Kärger model that resolves spine–shaft exchange explicitly, and a coarse‐grained Kärger model that absorbs spines into an effective ...

Sheath-run artificial muscles

open access: yes, 2019
Although guest-filled carbon nanotube yarns provide record performance as torsional and tensile artificialmuscles, they are expensive, and only part of themuscle effectively contributes to actuation.We describe a muscle type that provides higher ...
