The preliminary diffusion tensor imaging study of cerebral microstructure in the acute phase of brain concussion

Исследования и практика в медицине, 2019
Purpose of the study. Concussion does not cause any lesions available for visualization using computed tomography and magnetic resonance imaging. However, it can cause changes at the microstructural level, which can be detected by the diffusion-tensor ...

Compensated Diffusion Magnetic Resonance Imaging

Vision Letters, 2015
<p>This paper presents a novel compensated diffusion magnetic resonance<br />imaging (cdMRI) system for improved tissue detail and contrast<br />for screening and diagnosis. The proposed cdMRI system<br />incorporates the intrinsic properties of the MRI apparatus to compensate<br />for artifacts and degradation caused ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
