El fracaso del proyecto de ley de beneficios extraordinarios de Santiago Alba, en 1916: Una lectura política
Editada en la Fundación Empresa PúblicaEste artículo aborda dos aspectos importantes en la elaboración de las políticas fiscales durante la Restauración: la posición central del Parlamento en la toma de decisiones político-fiscales y las relaciones entre los partidos con representación parlamentaria y los grupos de presión. En 1916 el ministro de Hacienda Santiago Alba intentó incorporar al sistema tributario español un impuesto sobre los beneficios extraordinarios derivados, adoptado ya por la mayoría de los países beligerantes en la Primera Guerra Mundial y por algunos neutrales. El Proyecto de ley sucumbió en el Congreso de los Diputados debido a la obstrucción de un nutrido conjunto de diputados liderado por la Lliga Regionalista. Algunos historiadores han explicado la derrota del proyecto de Alba por la fuerza y la eficacia de los grupos de presión económicos y por la subordinación de los partidos políticos representados en el Parlamento a sus intereses. Este artículo discrepa de dicha tesis. Intenta demostrar que la actitud de la Lliga Regionalista vino determinada por razones estrictamente políticas. Su objetivo era debilitar el sistema político de la Restauración, considerado como una traba para el desarrollo de la autonomía catalana. En su lucha contra Alba, la Lliga recibió el apoyo de varios diputados que, sin el respaldo de sus partidos, actuaron en defensa de los intereses económicos afectados por el proyecto en sus distritos.This article deals with two important matters of the making of fiscal policy during the Spanish Restoration: the central position of the Parliament in the making of fiscal policy, and the relations between the parliamentary parties and the pressure groups. In the year 1916, the Spanish Chancellor of the Exchequer, the liberal Santiago Alba, tried to incorporate the War Profits Tax to the Spanish tax system, adopted by the majority of the countries at the First World War and by some neutral countries. The bill failed in the Parliament because of the obstruction of a large group of MPs leaded by the Lliga Regionalista, a Catalonian nationalist party. It is said by some historians that the failure of Alba's bill was due to the strength and the efficiency of the pressure groups and by the subordination of the parliamentary parties of their interests. This article disagrees with this thesis. It tries to prove that the attitude of the Lliga Regionalista was instigated by strictly political reasons. Its objective was to weaken the political system of Spanish Restoration. The Lliga considered that this political system was an obstacle for the development of the Catalonian home rule. In its struggle against Santiago Alba, the Lliga was supported by several MPs. They fought the bill in defence of the predominant economic interests in their electoral districts, without the support of their parties.Publicad
Testicular fusocellular rhabdomyosarcoma as a metastasis of elbow sclerosing rhabdomyosarcoma: A clinicopathologic, immunohistochemical and molecular study of one case
Sclerosing rhabdomyosarcoma (SRMS) is an infrequent variant of rhabdomyosarcoma characterized by extensive intercellular hyaline fibrosis. We report the case of a 37 year-old male with a 9 × 6 cm SRMS on the right elbow. Histologically, the tumor showed an abundant extracellular hyaline matrix with extratumoral vascular emboli and microscopic foci of fusocellular embryonal rhabdomyosarcoma (FRMS) separated by a fibrotic band from the sclerosing areas. One year later the patient presented with a right intratesticular tumor of 1.2 × 0.8 cm, which was reported as pure FRMS. Immunohistochemically, SRMS was positive only for MyoD1 and Vimentin and negative for Myogenin and Desmin. Both the elbow emboli with the extratumoral foci of FRMS and the intratesticular tumor were positive for Myogenin, MyoD1, Vimentin and Desmin. Using fluorescent in situ hybridization (FISH), the SRMS and the FRMS tumor cells of the elbow and the FRMS tumor cells of the testis were found to be negative for FOXO1A translocation in chromosome 13. PCR chimeric transcriptional products PAX3-FKHR and PAX7-FKHR were not found. Six months following testicular resection, the patient died of multiple metastases in the mediastinum, lung and right thigh
Liberalismo en un país con pocos liberales: España, 1808-1874
In 1808, the Liberal Revolution came about in a country with few liberals. It was not born from the impulse of its supporters, who found as a fait accompli the collapse of the institutional framework of the Old Regime after the Napoleonic invasion. Few and weak, the liberals took three decades to consolidate the revolution. The weak social base of liberalism would condition its consolidation and development in the middle years of the 19th century.En 1808, la revolución liberal llegó sobrevenida a un país con pocos liberales. No nació del impulso de sus partidarios, que hallaron como un hecho consumado el derrumbe del entramado institucional del Antiguo Régimen tras la invasión napoleónica. Pocos y débiles, los liberales tardaron tres décadas en consolidar la revolución. La débil base social del liberalismo español condicionaría su consolidación y desarrollo en los años centrales del siglo XIX

Identification of neuronal network properties from the spectral analysis of calcium imaging signals in neuronal cultures
Neuronal networks in vitro are prominent systems to study the development of connections in living neuronal networks and the interplay between connectivity, activity and function. These cultured networks show a rich spontaneous activity that evolves concurrently with the connectivity of the underlying network. In this work we monitor the development of neuronal cultures, and record their activity using calcium fluorescence imaging. We use spectral analysis to characterize global dynamical and structural traits of the neuronal cultures. We first observe that the power spectrum can be used as a signature of the state of the network, for instance when inhibition is active or silent, as well as a measure of the network's connectivity strength. Second, the power spectrum identifies prominent developmental changes in the network such as GABAA switch. And third, the analysis of the spatial distribution of the spectral density, in experiments with a controlled disintegration of the network through CNQX, an AMPA-glutamate receptor antagonist in excitatory neurons, reveals the existence of communities of strongly connected, highly active neurons that display synchronous oscillations. Our work illustrates the interest of spectral analysis for the study of in vitro networks, and its potential use as a network-state indicator, for instance to compare healthy and diseased neuronal networks
Actualización en el tratamiento del dolor orofacial
En los últimos años se han desarrollado nuevos tratamientos en
el dolor orofacial. En la cefalea en racimos se ha incorporado la
administración de nuevos fármacos por vía intranasal. En el
dolor masticatorio la aplicación tópica de capsaicina y el uso
de férulas orales en combinación con ejercicios de movilización
mandibular, son los tratamientos más utilizados. En el dolor
neurógeno se han desarrollando nuevos fármacos anticonvulsivos
con menos efectos secundarios que la carbamacepina. Los
últimos avances farmacológicos se dirigen hacia el uso de
AINES y opioides de forma tópica y hacia la combinación de
distintos analgésicos. Comentamos en este trabajo de revisión
los últimos avances en el tratamiento del dolor orofacial
Correcting loss of a papilla following orthodontic space opening (Atherton's patch) through implant supported rehabilitation. A case report
The objective of this case report is to describe a surgical and prosthetic technique to create a lost papilla following
orthodontic space opening (Atherton`Ls patch) through implant supported rehabilitation.
A switching platform implant was used to replace a left maxillary canine in a unitary interdental edentulous ridge
with Atherton'Ls patch in the distal area of the upper lateral left incisor. The radiographic study revealed correct level
of the interproximal bone of the adjacent teeth. A mucoperiosteal flap with crest incision and sulcular extension to
the adjacent teeth was made. Special attention was paid to correct position of the implant and the distance (. 1.5
mm) between the platform and the roots of the adjacent teeth. A submerged technique was used. Tissue modeling
through provisional crown was performed in order to create an ideal emergence profile with total papilla fill recorded
at the Atherton'Ls patch area. Final screw retained CAD-CAM zirconia structure was place. Final follow up was
performed 2 years after provisional crown placement, and total fill of both papilla, including at Atherton'Ls patch
area, was recorded
Periapical surgery of maxillary posterior teeth : A review of the literature
In recent years, periapical surgery has evolved thanks to new diagnostic and technical advances. A review is made of the literature on periapical surgery of the antral teeth, based on a Medline search and on the revision of Spanish dental journals in the period between 1974 and 2003. The anatomy of the maxillary sinus is discussed, along with the diagnosis of periapical lesions and the relation of the maxillary sinus to the antral teeth. The surgical technique, special considerations and prognosis of periapical surgery in these teeth are also addressed. Recent studies postulate that the proximity of the antral teeth to the maxillary sinus should not be viewed as a contraindication to periapical surgery, and recommend such surgery in teeth with chronic periapical disease that are refractory to conventional endodontic management, despite the proximity of the maxillary sinus
