A Guideline to Univariate Statistical Analysis for LC/MS-Based Untargeted Metabolomics-Derived Data.

Metabolites

Vinaixa M, Samino S, Saez I, Duran J, Guinovart JJ, Yanes O.
PMID: 24957762
Metabolites. 2012 Oct 18;2(4):775-95. doi: 10.3390/metabo2040775.

Several metabolomic software programs provide methods for peak picking, retention time alignment and quantification of metabolite features in LC/MS-based metabolomics. Statistical analysis, however, is needed in order to discover those features significantly altered between samples. By comparing the retention...

The Analyst

Novell M, Guinovart T, Steinberg IM, Steinberg M, Rius FX, Andrade FJ.
PMID: 23857560
Analyst. 2013 Sep 21;138(18):5250-7. doi: 10.1039/c3an00727h. Epub 2013 Jul 16.

Instrumental approaches to remotely and wirelessly monitoring chemical species are increasingly needed. Together with the electronic developments, efforts to optimize and validate the performance of these new devices are required. In this work, the analytical performance of a recently...

Spectral counting assessment of protein dynamic range in cerebrospinal fluid following depletion with plasma-designed immunoaffinity columns.

Clinical proteomics

Borg J, Campos A, Diema C, Omeñaca N, de Oliveira E, Guinovart J, Vilaseca M.
PMID: 21906361
Clin Proteomics. 2011 Jun 03;8(1):6. doi: 10.1186/1559-0275-8-6.

BACKGROUND: In cerebrospinal fluid (CSF), which is a rich source of biomarkers for neurological diseases, identification of biomarkers requires methods that allow reproducible detection of low abundance proteins. It is therefore crucial to decrease dynamic range and improve assessment...

Role of brain glycogen in the response to hypoxia and in susceptibility to epilepsy.

Frontiers in cellular neuroscience

López-Ramos JC, Duran J, Gruart A, Guinovart JJ, Delgado-García JM.
PMID: 26578889
Front Cell Neurosci. 2015 Oct 27;9:431. doi: 10.3389/fncel.2015.00431. eCollection 2015.

Although glycogen is the only carbohydrate reserve of the brain, its overall contribution to brain functions remains unclear. It has been proposed that glycogen participates in the preservation of such functions during hypoxia. Several reports also describe a relationship...

Evaluating the impact of programmatic mass drug administration for malaria in Zambia using routine incidence data.

The Journal of infectious diseases

Fraser M, Miller JM, Silumbe K, Hainsworth M, Mudenda M, Hamainza B, Moonga H, Chizema Kawesha E, Mercer LD, Bennett A, Schneider K, Slater HC, Eisele TP, Guinovart C.
PMID: 32691047
J Infect Dis. 2020 Jul 21; doi: 10.1093/infdis/jiaa434. Epub 2020 Jul 21.

BACKGROUND: In 2016, the Zambian National Malaria Elimination Centre started programmatic mass drug administration (pMDA) campaigns with dihydroartemisinin-piperaquine as a malaria elimination tool in Southern Province. Two rounds were administered, two months apart (coverage 70% and 57% respectively). We...

This article describes a course for reinforcing the knowledge of biochemistry in secondary school science teachers. The Department of Biochemistry and Molecular Biology of the University of Barcelona designed a course to bring these teachers up to date with...

p38γ and p38δ regulate postnatal cardiac metabolism through glycogen synthase 1.

PLoS biology

Santamans AM, Montalvo-Romeral V, Mora A, Lopez JA, González-Romero F, Jimenez-Blasco D, Rodríguez E, Pintor-Chocano A, Casanueva-Benítez C, Acín-Pérez R, Leiva-Vega L, Duran J, Guinovart JJ, Jiménez-Borreguero J, Enríquez JA, Villlalba-Orero M, Bolaños JP, Aspichueta P, Vázquez J, González-Terán B, Sabio G.
PMID: 34758018
PLoS Biol. 2021 Nov 10;19(11):e3001447. doi: 10.1371/journal.pbio.3001447. eCollection 2021 Nov.

During the first weeks of postnatal heart development, cardiomyocytes undergo a major adaptive metabolic shift from glycolytic energy production to fatty acid oxidation. This metabolic change is contemporaneous to the up-regulation and activation of the p38γ and p38δ stress-activated...

Astrocytic glycogen accumulation drives the pathophysiology of neurodegeneration in Lafora disease.

Brain : a journal of neurology

Duran J, Hervera A, Markussen KH, Varea O, López-Soldado I, Sun RC, Del Río JA, Gentry MS, Guinovart JJ.
PMID: 33822008
Brain. 2021 Sep 04;144(8):2349-2360. doi: 10.1093/brain/awab110.

The hallmark of Lafora disease, a fatal neurodegenerative disorder, is the accumulation of intracellular glycogen aggregates called Lafora bodies. Until recently, it was widely believed that brain Lafora bodies were present exclusively in neurons and thus that Lafora disease...
