The urban rent in the multicultural city: retail shops, migrants and urban decline in the historic centre of Palermo [La rendita urbana nella città m…
2020
Changes in consumer shopping behavior and in retail spaces, such as shopping malls, department stores and e-commerce, have modified localization models of traditional retail shops, also affecting urban fabric and spatial distribution of urban rent. Even city centers have undergone significant transformations or even decline, especially if local economic system and real estate market are weak and recessionary. A significant amount of commercial properties may have long vacancy due to excess supply, since many traditional shops close their business because they are no longer competitive and, moreover, there is no immediate takeover by new tenants. The decline of central urban areas depends on…
Estudio de la vía visual mediante tomografía de coherencia óptica y resonancia magnética cerebral y medular para la formulación y validación de model…
2020
Estudiar la correlación entre valores de tomografía de coherencia óptica (OCT, Optical Coherence Tomography) peripapilar y macular con volumetrías cerebrales y espinales determinadas a partir de imágenes de resonancia magnética (RM), teniendo en cuenta el tipo de esclerosis múltiple (EM) y el antecedente de neuritis óptica (NO). Formular y validar modelos matemáticos para la predicción de la discromatopsia y de la discapacidad a partir de marcadores clínicos y paraclínicos. MATERIAL Y MÉTODO: Estudio observacional, analítico y transversal de 92 pacientes de la Unidad Mixta de EM y Neurorregeneración del Hospital Universitario y Politécnico La Fe de Valencia. De cada paciente se recogieron l…
Retinal Vascular Assessment in Psoriasis: A Multicenter Study
2021
PurposeTo investigate the vascular status of the macula in psoriasis patients without history of ocular inflammation by Optical Coherence Tomography Angiography (OCTA).MethodsThis prospective cross-sectional multicenter study included 55 psoriasis patients and 55 control healthy subjects. A complete eye examination and 6 mm × 6 mm OCTA imaging were performed. Retinal vascular status was evaluated by analyzing vascular density (VD) of superficial vascular plexus (superficial wVD) and deep vascular plexuses (deep wVD) in a 6 mm × 6 mm area and in foveal (superficial fVD and deep fVD) and parafoveal sectors (superficial pVD and deep pVD). In addition, foveal thickness (FT) and foveal avascular…

FUNCIONAMIENTO EJECUTIVO TEMPRANO EN NIÑOS CON DIFICULTADES MATEMÁTICAS PERSISTENTES
2016
El objetivo del presente estudio consistió en examinar las diferencias en las funciones ejecutivas de inhibición y memoria de trabajo (MT) evaluadas en Educación Infantil entre sujetos con dificultades persistentes en el área de matemáticas en 2º de Educación Primaria y niños con un rendimiento adecuado. La muestra final del estudio estuvo conformada por 180 niños (inicialmente compuesta por 209 preescolares), de los cuales un 6.6% presentaron dificultades matemáticas persistentes (n = 12) y el 45.5% mostraron un rendimiento adecuado en ambas mediciones (n = 82). En Educación Infantil, se administraron seis tareas neuropsicológicas relacionadas con las funciones ejecutivas de inhibición, MT…
New genera, species and records of Phaneropterinae (Orthoptera, Phaneropteridae) from sub-Saharan Africa
2015
The results of the study of many specimens preserved in different European museums are reported. The tribe Terpnistrini Brunner von Wattenwyl, 1878 is resurrected. The distribution of the following species is enhanced: Pardalotaasymmetrica Karsch, 1896, Diogenadenticulata Chopard, 1954, Diogenafausta (Burmeister, 1838), Plangiopsisadeps Karsch, 1896, Poreuomenasanghensis Massa, 2013 and Tylopsiscontinua (Walker, 1869). Further, for their peculiar characteristics, two African representatives of the American genus Symmetropleura Brunner von Wattenwyl, 1878 are included in two new genera: Symmetrokarschiaafricana (Brunner von Wattenwyl, 1878), comb. n. and Symmetroraggeadirempta (Karsch, 1889)…
Delivery of proteins into living cells by reversible membrane permeabilization with streptolysin-O
2001
The pore-forming toxin streptolysin O (SLO) can be used to reversibly permeabilize adherent and nonadherent cells, allowing delivery of molecules with up to 100 kDa mass to the cytosol. Using FITC-labeled albumin, 10 5 –10 6 molecules were estimated to be entrapped per cell. Repair of toxin lesions depended on Ca 2+ -calmodulin and on intact microtubules, but was not sensitive to actin disruption or to inhibition of protein synthesis. Resealed cells were viable for days and retained the capacity to endocytose and to proliferate. The active domains of large clostridial toxins were introduced into three different cell lines. The domains were derived from Clostridium difficile B-toxin and Clo…

Septo-optic dysplasia and schizencephaly: a case report
2012
Introduction: Septo-optic dysplasia (SOD) is an uncommon developmental disorder involving variable midline brain structures, characterized by optic nerve hypoplasia, dysgenesis of septum pellucidum and pituitary- hypothalamic dysfunction with consequent endocrine deficits. The association of septo-optic dysplasia and cortical dysplasia is described as septo-optic dysplasia-plus. Reports on patients with septo-optic dysplasia-plus have been rare. Other distinct features, which occur especially when cerebral cortical abnormalities are also present (SOD- plus), consist of significant generalized developmental delay and/or spastic motor deficits. Methods: We report a 10-year-old boy with septo-…
