Ultra high-resolution HSQC: Application to the efficient and accurate measurement of heteronuclear coupling constants

Journal cover: Chemical Communications“Ultra high-resolution HSQC: Application to the efficient and accurate measurement of heteronuclear coupling constants” by Núria Marcó,  Andre Fredi and Teodor Parella. Chemical Communications 2015, 51:3262-3265. DOI: 10.1039/C4CC10279G

A rapid NMR data acquisition strategy in terms of enhanced resolution per time unit for the simple and efficient determination of multiple coupling constants is described. The use of 13C spectral aliasing combined with broadband 1H homodecoupling allows accurate measurements from ultra high resolved 2D HSQC cross-peaks.imagen4

Hyperpolarized 13C Magnetic Resonance in Acute Liver Failure Rats

2014_coverNMinBiomedReal-time assessment of 13C metabolism  reveals an early lactate increase in the brain of rats with acute liver failure” by Laia Chavarria, Jordi Romero-Giménez, Eva Monteagudo, Silvia Lope-Piedrafita, Juan Cordoba. NMR in Biomedicine (2014) 28:17-23. DOI: 10.1002/nbm.3226

Intracranial hypertension is a severe complication of acute liver failure (ALF) secondary to brain edema. The pathogenesis of cerebral edema in ALF is not clear, but seems to be related to energy metabolism in which lactate may have an important role. The aim of this study was to follow the synthesis of brain lactate using a novel in vivo metabolic technology in a rat model of ALF.

Ex vivo method to evaluate MRI contrast agents

“A 2014_coverJnanobiotechnologynew ex vivo method to evaluate the performance of candidate MRI contrast agents: a proof-of-concept study” by Candiota A.P., Acosta M., Simões R.V., Delgado-Goñi T., Lope-Piedrafita S., Irure A., Marradi M., Bomatí-Miguel O., Miguel-Sancho N., Abasolo I., Schwartz S. Jr., Santamaría J., Penadés S., Arús C. J Nanobiotechnology 2014 12:12. DOI: 10.1186/1477-3155-12-12.

A new method has been developed for selecting MRI contrast agents with better expected in vivo performance. This method requires only a very small amount of contrast agent (e.g. 5 nmols/animal, 800 times less than the quantity necessary for in vivo administration) and allows to carry out a more rationally informed candidate selection, avoiding unnecessary in vivo and toxicology tests for the ex vivo poorly performing substances, consequently reducing animal needs, material consumption and overall costs.

Opposite metabolic responses of shoots and roots to drought

scireports Opposite metabolic responses of shoots and roots to drought by Albert Gargallo-Garriga, Jordi Sardans, Míriam Pérez-Trujillo, Albert Rivas-Ubach, Michal Oravec, Teodor Parella and Josep Peñuelas. Scientific reports 4, Article number: 6829, October 2014. DOI: 10.1038/srep06829

Shoots and roots are autotrophic and heterotrophic organs of plants with different physiological functions. Do they have different metabolomes? Do their metabolisms respond differently to environmental changes such as drought? We used metabolomics and elemental analyses to answer these questions.
