In vivo microstructural heterogeneity of white matter and cognitive correlates in aging using tissue compositional analysis of diffusion magnetic resonance imaging

Human Brain Mapping, Volume 45, Issue 4, March 2024.
This study investigates the relationship between age‐related cognitive decline, white matter signal abnormalities (WMSA), and changes in white matter (WM) microstructure. Using single‐shell 3‐tissue constrained spherical deconvolution (SS3T‐CSD), we can differentiate WMSA from normal‐appearing white matter and analyze their association with cognition ...

Superparamagnetic Nanoparticles with Phosphorescent Complexes as Hybrid Contrast Agents: Integration of MRI and PLIM

Small Science, Volume 4, Issue 3, March 2024.
Two hybrid nanosystems are prepared by loading magnetite nanocubes with two tailor‐made phosphorescent Pt(II) complexes. The nanohybrids exhibit two orthogonal readouts in agarose phantoms: enhanced magnetic resonance imaging (MRI) contrast compared to ferucarbotran and phosphorescence in the microsecond range, which is a significant advantage when ...

Cortical and subcortical microstructure integrity changes after repetitive transcranial magnetic stimulation therapy in cocaine use disorder and relates to clinical outcomes

Addiction Biology, Volume 29, Issue 2, February 2024.
We evaluated whether active repetitive transcranial magnetic stimulation over the left dorso‐lateral prefrontal cortex (dlPFC) has an effect on the white matter microstructure in cocaine use disorder (CUD) patients. For this, we acquired MRI data and assessed the clinical status.

Miocarditis aguda: diagnóstico mediante resonancia magnética cardiaca [PDF]

, 2009
Cardiomyopathies are a common cause of morbidity and mortality. Myocarditis, which is included among specific cardiomyopathies, frequently presents non-specific clinical manifestations and thus may be difficult to diagnose, or even be misdiagnosed ...

Empathy‐related differences in the anterior cingulate functional connectivity of regular cannabis users when compared to controls

Journal of Neuroscience Research, Volume 102, Issue 1, January 2024.
Differences in emotional comprehension and functional connectivity of the anterior cingulate cortex between regular cannabis users and controls. Abstract It has been reported that cannabis consumption affects the anterior cingulate cortex (ACC), a structure with a central role in mediating the empathic response.

Effect of the addition of nanosilica on white cement hydration at 25°C

MATEC Web of Conferences, 2014
The cement industry is keen on reducing natural resource consumption, reusing waste that would otherwise be sent to a rubbish tip and lowering its CO2 emissions. In pursuit of those objectives, the addition of materials such as silica fume, ceramic waste,
