Quantitative Determination of Acrolein in Cider by 1H NMR Spectrometry
; ; ; Bordagaray Eizaguirre, Ane; Dueñas Chasco, María Teresa ; Berregi Abalde, Iñaki (MDPI, 2020-12-08)
Acrolein occasionally appears in cider, completely spoiling its quality due to its bitter taste. It is crucial to detect it in the early steps, before the taste is severely affected, to apply the appropriate treatment. A ... -
Quantitative determination of fentanyl in newborn pig plasma and cerebrospinal fluid samples by HPLC-MS/MS

In this study, a selective and sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method requiring low sample volume (≤100 μL) was developed and validated for the quantitative determination ... -
Quantitative proteomic analysis of Parkin substrates in Drosophila neurons
Martínez Zárate, Aitor; Lectez, Benoit; Ramírez Sánchez, Juan Manuel; Popp, Oliver; Sutherland, James D.; Urbé, Sylvie; Dittmar, Gunnar; Clague, Michael J.; Mayor Martínez, Ugo (Biomed Central, 2017-04-11)
Background: Parkin (PARK2) is an E3 ubiquitin ligase that is commonly mutated in Familial Parkinson's Disease (PD). In cell culture models, Parkin is recruited to acutely depolarised mitochondria by PINK1. PINK1 activates ... -
Quantitative super-resolution imaging of pathological aggregates reveals distinct toxicity profiles in different synucleinopathies
; ; ; ; Franco Budia, Aitor; ; ; Muga Villate, Arturo ; (National Academy of Sciences, 2022-10)
Protein aggregation is a hallmark of major neurodegenerative disorders. Increasing data suggest that smaller aggregates cause higher toxic response than filamentous aggregates (fibrils). However, the size of small aggregates ... -
Quantum anharmonic enhancement of superconductivity in P63/mmc ScH6 at high pressures: A first-principles study

Making use of first-principles calculations, we analyze the effect of quantum ionic fluctuations and lattice anharmonicity on the crystal structure and superconductivity of P63/mmc ScH6 in the 100–160 GPa pressure range ... -
Quantum Artificial Life in an IBM Quantum Computer
Álvarez Rodríguez, Unai; Sanz Ruiz, Mikel; Lamata Manuel, Lucas ; Solano Villanueva, Enrique Leónidas (Nature Publishing, 2018-10-04)
We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, ... -
Quantum cosmology of the Big Rip: Within GR and in a modified theory of gravity
Bouhmadi López, Mariam; Albarran, Imanol; Chen, Che-Yu (MDPI, 2017-04-14)
Quantum gravity is the theory that is expected to successfully describe systems that are under strong gravitational effects while at the same time being of an extreme quantum nature. When this principle is applied to the ... -
