Extreme diffusion values for non-Gaussian diffusions [PDF]

open access: yes, 2008
A new magnetic resonance imaging (MRI) model, called diffusion kurtosis imaging (DKI), was recently proposed, to characterize the non-Gaussian diffusion behaviour in tissues.

Compensated Diffusion Magnetic Resonance Imaging

open access: yesVision 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

open access: yesFEBS 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 ...

In vivo contrast free chronic myocardial infarction characterization using diffusion-weighted cardiovascular magnetic resonance. [PDF]

open access: yes, 2014
BackgroundDespite the established role of late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) in characterizing chronic myocardial infarction (MI), a significant portion of chronic MI patients are contraindicative for the use of ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
