Brain magnetic resonance in liver failure

Methods & Applications, Our Publications, Our Research, , , ,

“Brain magnetic resonance in experimental acute-on-chronic liver failure” by L. Chavarria, M. Oria, J. Romero-Giménez, J. Alonso, S. Lope-Piedrafita, and J. Cordoba.
Liver International 33 (2013) 294-300. DOI: 10.1111/liv.12032

Liver failure causes brain edema that can lead to intracranial hypertension and death. It is currently uncertain whether this water accumulation is predominantly intracellular or extracellular, something important to determine in order to apply the most adequate therapeutic measures. The aim of this study was to investigate the mechanisms involved in the neurological manifestations occurring in an experimental acute-on-chronic liver failure rat model that combines sustained liver injury with a factor inducing an inflammatory response.

“Dilated cardiomyopathy and mitochondrial dysfunction in Sirt1-deficient mice: A role for Sirt1-Mef2 in adult heart”
 by A. Planavila, E. Dominguez, M. Navarro, M. Vinciguerra, R. Iglesias, M. Giralt, S. Lope-Piedrafita, J. Ruberte, F. Villarroya. Journal of Molecular and Cellular Cardiology 53 (2012) 521-531. DOI: 10.1016/j.yjmcc.2012.07.019

The protein deacetylase Sirtuin-1 (Sirt1) is involved in the cardiac hypertrophic responses and cardiac embryo morphogenesis. However, the physiological function of Sirt1 deficiency in the postnatal development of the heart remains to be characterized. The aim of this study was to investigate the relevance of Sirt1 in the development and function of the myocardium by using complementary techniques, such as gene expression, immunoblotting, immunohistochemistry, histological and electron microscopy examinations, and in vivo cardiac magnetic resonance imaging (MRI).

“Dimethyl sulfoxide (DMSO) as a potential contrast agent for brain tumors”, by Delgado-Goñi T, Martín-Sitjar J, Simões RV, Acosta M, Lope-Piedrafita S, Arús C.; NMR in Biomedicine. 2012.DOI: 10.1002/nbm.2832.

Identifying the type of brain tumor helps doctors determine the most appropriate course of treatment. Brain tumor diagnosis usually involves a neurological examination, brain scans, and/or an analysis of the brain tissue. Nowadays, the biopsy, although it is a very invasive procedure, is the most accurate method of obtaining a diagnosis. Continue reading DMSO as a magnetic resonance contrast agent for brain tumors →

Novel MRI contrast agents: peptide-SPION conjugates

Journal Cover:Chem. Commun., 2012, 48, 5322-5324“Efficient γ-amino-proline-derived cell penetrating peptide-superparamagnetic iron oxide nanoparticle conjugates via aniline-catalyzed oxime chemistry as bimodal imaging nanoagents”, by Cavalli S, Carbajo D, Acosta M, Lope-Piedrafita S, Candiota AP, Arús C, Royo M, Albericio F; Chem. Commun 48 (2012) p. 5322. DOI: 10.1039/C2CC17937G

Recent advances in nanotechnology have offered new opportunities for detection, prevention, and treatment of different diseases. In this respect engineered superparamagnetic iron oxide nanoparticles (SPIONs) represent an advanced tool in nanomedicine because they can be loaded in a multiple and orthogonal way with drugs and probes in order to simultaneously act as molecular imaging agents and drug carriers.

Hyperpolarized 13C magnetic resonance metabolic imaging in a mouse brain glioma model

Methods & Applications, News from the SeRMN, , , ,

Magnetic resonance spectroscopic imaging (MRSI) of hyperpolarized [1-13C]pyruvate is a promising technique to noninvasively monitor metabolic changes in vivo. This method uses dynamic nuclear polarization (DNP) techniques to obtain tens of thousands fold enhancement in the polarization of [1-13C]pyruvate and its metabolic products, like lactate, providing sufficient MR signal for high spatial and temporal resolution spectroscopic imaging of these metabolites.
