Spectroscopic and Structural Investigation of the Confinement of D and L Dimethyl Tartrate in Lecithin Reverse Micelles
2009
The confinement of D and L dimethyl tartrate in lecithin reverse micelles dispersed in cyclohexane has been investigated by FT-IR, polarimetry, electronic and vibrational circular dichroism (ECD and VCD), 1H NMR, and small-angle X-ray scattering (SAXS). Measurements have been performed at room temperature as a function of the solubilizate-to-surfactant molar ratio (R) at fixed lecithin concentration. The analysis of experimental data indicates that the dimethyl tartrate molecules are solubilized within reverse micelles in proximity to the surfactant head groups in the same way for the D and L forms. The encapsulation of dimethyl tatrate within lecithin reverse micelles involves changes in i…
La Leucemia Linfática Crónica: evolución clonal y su monitorización molecular
2023
La estratificación pronóstica de los pacientes con Leucemia Linfática Crónica (LLC) se basa en el índice pronóstico LLC-IPI, que integra marcadores clínicos, citogenéticos y biológicos, como el estudio de la región variable del gen de la cadena pesada de las inmunoglobulinas (IGVH) y del gen TP53. La secuenciación de nueva generación (NGS), ha permitido identificar las alteraciones genéticas asociadas con el desarrollo, progresión y resistencia a los tratamientos convencionales, y desarrollar nuevas herramientas pronósticas, y novedosas terapias dirigidas. Con la inmunoquimioterapia (IQT), la evolución clonal después de la terapia es la regla, mientras que con Ibrutinib, es la adaptación de…
It's Sad but I Like It The Neural Dissociation Between Musical Emotions and Liking in Experts and Laypersons
2016
Emotion-related areas of the brain, such as the medial frontal cortices, amygdala, and striatum, are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a …
Interactive case discussion
2011
Incidental lesions are frequently discovered during routine radiographic evaluations. Correlation with clinical history and additional confirmatory imaging is essential to the development of an accurate, focused differential diagnosis and for appropriate management. The objective of this presentation is to describe the imaging findings associated with incidentally found liver lesions and to review those clinical and radiologic features, which should be considered in development of an ordered and accurate differential diagnosis. Learning Objectives: 1. To introduce typical cases illustrating the role of imaging modalities in the differential diagnosis of unexpected liver lesion cases. 2. To …

TRANS-FUSIMO: Preliminary in-vivo animal results of MR-guided Focused Ultrasound of liver under respiratory motion
2018
Background: Treating liver tumors using FUS poses a great challenge due to the respiratory motion of the target and by the rib cage obscuring the anatomical location of the malignancy. In the EU FP7 project TRANS-FUSIMO (www.trans-fusimo.eu) a novel treatment software has been developed to support MR guided focused ultrasound treatment of liver lesions through electronic real-time beam steering of the ultrasound transducer. Prior to clinical use we conduct an in-vivo animal trial using the TRANS-FUSIMO treatment system (TTS) to evaluate the safety and the technical efficacy and efficiency of generation predefined necrotic lesions in the healthy liver. Material and Methods: The pre-clinical …
