Ciència catalana a Madrid: el discurs de Jesús M. Bellido Golferichs a la Biblioteca Nacional (1927)

We analyze Dr. Bellido"s discourse at the Spanish National Library in Madrid (1927) in the framework of what has been called Medical Catalanism. Further development of this case study will provide a better understanding of Catalan as a scientific language, the importance of the role played by Catalan publishing industry and the cultural and political relationship between Madrid and Barcelona.

Do protein–protein interaction databases identify moonlighting proteins?

One of the most striking results of the human (and mammalian) genomes is the low number of protein-coding genes. To-date, the main molecular mechanism to increase the number of different protein isoforms and functions is alternative splicing. However, a less-known way to increase the number of protein functions is the existence of multifunctional, multitask, or ‘‘moonlighting’’, proteins. By and large, moonlighting proteins are experimentally disclosed by serendipity. Proteomics is becoming one of the very active areas of biomedical research, which permits researchers to identify previously unseen connections among proteins and pathways. In principle, protein–protein interaction (PPI) databases should contain information on moonlighting proteins and could provide suggestions to further analysis in order to prove the multifunctionality. As far as we know, nobody has verified whether PPI databases actually disclose moonlighting proteins. In the present work we check whether well-established moonlighting proteins present in PPI databases connect with their known partners and, therefore, a careful inspection of these databases could help to suggest their different functions. The results of our research suggest that PPI databases could be a valuable tool to suggest multifunctionality.

Multislice CT for assessing in-stent dimensions after left main coronary artery stenting: a comparison with three dimensional intravascular ultrasound

Objective: To evaluate the agreement between multislice CT (MSCT) and intravascular ultrasound (IVUS) to assess the in-stent lumen diameters and lumen areas of left main coronary artery (LMCA) stents. Design: Prospective, observational single centre study. Setting: A single tertiary referral centre. Patients: Consecutive patients with LMCA stenting excluding patients with atrial fibrillation and chronic renal failure. Interventions: MSCT and IVUS imaging at 912 months follow-up were performed for all patients. Main outcome measures: Agreement between MSCT and IVUS minimum luminal area (MLA) and minimum luminal diameter (MLD). A receiver operating characteristic (ROC) curve was plotted to find the MSCT cut-off point to diagnose binary restenosis equivalent to 6 mm2 by IVUS. Results: 52 patients were analysed. PassingBablok regression analysis obtained a β coefficient of 0.786 (0.586 to 1.071) for MLA and 1.250 (0.936 to 1.667) for MLD, ruling out proportional bias. The α coefficient was −3.588 (−8.686 to −0.178) for MLA and −1.713 (−3.583 to −0.257) for MLD, indicating an underestimation trend of MSCT. The ROC curve identified an MLA ≤4.7 mm2 as the best threshold to assess in-stent restenosis by MSCT. Conclusions: Agreement between MSCT and IVUS to assess in-stent MLA and MLD for LMCA stenting is good. An MLA of 4.7 mm2 by MSCT is the best threshold to assess binary restenosis. MSCT imaging can be considered in selected patients to assess LMCA in-stent restenosis

Dr. Pedro Gómez de Almodóvar (1601-1667). Médico, matemático y astrónomo hellinense

En este artículo se presentan una serie de datos biográficos que dan luz sobre la vida del Dr. Pedro Gómez de Almodóvar, médico, matemático y astrónomo hellinense del siglo XVII. La revisión de libros sacramentales, así como el análisis de diversas escrituras notariales (testamentos, inventarios, ventas, etc.) aportan nuevos datos sobre este personaje descubierto por Francisco Mendoza y Luis-Guillermo García-Sauco hace ya 30 años cuando publicaron su interesante biblioteca.

A synthetic approach to palmerolides via Negishi cross coupling. The challenge of the C15-C16 bond formation

The esterification of fragment C1-C8 (2) with fragment C16-C23 (3) to give iodo derivative 4, followed by a Pd-catalysed coupling with a C9-C15 fragment (7 or 8), may provide a common precursor of most palmerolides. Ligands and reaction conditions were exhaustively examined to perform the C15-C16 bond formation via Negishi reaction. With simple models, pre-activated Pd-Xantphos and Pd-DPEphos complexes were the most efficient catalysts at RT. Zincation of the C9-C15 fragment (8) and cross coupling with 4 required 3 equiv of t-BuLi, 10 mol % of Pd-Xantphos and 60 °C.

Diseño de aplicativos de "autodiagnóstico sectoriales" como soporte del trabajo autónomo en el nuevo EEES

El objetivo de estos aplicativos, centrados cada uno de ellos en diferentes sectores de la economía, es facilitar la consecución de uno de los objetivos vinculados a la implantación del Espacio Europeo de Enseñanza Superior (EEES), donde se establece que el proceso formativo universitario debe basarse en desarrollar el estudio continuado y autónomo de los estudiantes (self-regulated/managed learning). Nuestro aplicativo informático es un instrumento mediante el cual el alumno, de forma autónoma, puede autoevaluar cuál es su nivel de conocimiento de los contenidos de las asignaturas de Estadística (grado de A.D.E. de la Universitat de Barcelona) a través del análisis de una empresa ubicada en un determinado sector económico. En este sentido, también puede entenderse como un material didáctico en la línea del llamado aprendizaje basado en problemas (problem-based learning). Con una estructura dinámica, basada en cuestiones de opción múltiple, e incorporada como módulo dentro de la plataforma Moodle (utilizada por la Universitat de Barcelona), permite una ejecución "on-line" de su contenido. Nuestra herramienta es un ejemplo más de cómo el uso de las nuevas tecnologías de la información y la comunicación (TIC), puede contribuir enormemente a la innovación de los procesos de enseñanza-aprendizaje en el contexto universitario1

Biomecánica de las afecciones neurológicas del pie. Tratamiento ortopodológico

Presentamos un caso de pie neurológico secundario a una Espina Bífida Quística en región lumbosacra con afectación de L5- SI. El paciente presenta una marcha en pseudoestepagge. Pie derecho equino y pie izquierdo cavo anterior que provocan lesiones cutáneas plantares múltiples, interfiriendo todo ello el curso normal de la vida del paciente. Se realizó un tratamiento ortopodológico durante seis años, ensayándose distintos tipos de plantillas y diversos materiales, que han dado como resultado una marcha casi normal en la actualidad.
