Interference between shallow and deep-seated structures in the Sicilian fold and thrust belt.
2010
Abstract: The fold and thrust belt in western Sicily is characterized by the presence and interference of shallow and deep-seated compressional structures, which were generated and developed at different structural levels. The shallow structures consist of imbricated thrusts and asymmetric folds, with a typical wavelength of 2 km, involving relatively thin deep-water units. These units are superimposed on thick platform carbonate units, along a wide and originally almost flat floor thrust. The axial trend of the folds is variable, as multi-phase folding often occurred, producing a characteristic interference pattern, reflecting continuous variations of the apparent transport direction durin…
Rift-controlled fluvial/tidal transitional series in the Oukai¨meden Sandstones, High Atlas of Marrakesh (Morocco)
1996
Abstract The Carnian formation of the Oukai¨meden Sandstones was deposited in the northwestern corner of the African craton along tectonic troughs grouped as a WSW-ENE rift system on the southwestern margin of the Tethys. Red sandstones represent mainly distal braided-stream deposits where very extensive sand flats with 3D dunes, 2D sand waves and high-regime horizontally laminated sandstones predominate. The similarities in orientation between current patterns and trough border faulting, the sudden large variations in the thickness of deposits and the occurrence of lateral alluvial fans along the marginal faults are all evidence of the tectonic control of sedimentation. The middle part of …
Sedimentological and geoarchaeological evidence of multiple tsunamigenic imprint on the Bay of Palairos-Pogonia (Akarnania, NW Greece)
2010
Abstract This paper presents evidence of multiple tsunami impact on the Bay of Palairos-Pogonia, NW Greece, during the Holocene based on detailed geo-scientific studies. Altogether, 41 vibracores were drilled to detect high-energy influence in the stratigraphical record. Layers of coarse-grained allochthonous marine deposits were found intersecting autochthonous fine-grained back beach sediments in the Palairos coastal plain, on top of beach or marly bedrock units at Pogonia beach and along the Pogonia cliff section. High-energy deposits are associated with specific sedimentary structures such as fining upward sequences, rip up-clasts, basal erosional contact, bi- to multimodal grain size d…
Gold nanoprobe-based detection of human telomerase reverse transcriptase (hTERT) Gene Expression
2015
Human Telomerase Reverse Transcriptase (hTERT) gene is expressed in all types of cancers, and it is considered as unique biomarker for early detection, monitoring and prognosis of different cancers. Routinely, the main techniques for detection of hTERT gene expression are based on enzymatic amplifications which need specified equipments, expert personnel and high cost and time. With regarding to the clinical importance of analysis of hTERT gene expression, we have developed a rapid, simple and low cost method which detects hTERT RNA target in 5 $\mu {\rm l}$ reaction scale using gold nanoprobes. The method is based on the inhibition of nanoparticle aggregation in the presence of ${\rm MgCl}…
«Deberías adelgazar, te lo digo porque te quiero»: reflexiones autoetnográficas sobre la gordura
2021
La reciente construcción de una epidemia de obesidad global favorece que -además de ser estéticamente deseable- la delgadez se considere autoevidencia del estado de salud del individuo y marca de moralidad. En esta autoetnografía reflexiono sobre mi vivencia de ser gorda desde la infancia hasta la adultez, desde un enfoque sociológico feminista. La imposición cultural de la delgadez y la gordofobia alimentaron sentimientos de incapacidad, inadecuación corporal y sufrimiento psicológico que promovieron conductas alimentarias problemáticas. Mi argumento es que la guerra contra la obesidad opera en nombre de la salud, pero produce una renuncia significativa al bienestar físico y psicológico en…
Grammar types in language explain tone sequence processing in music
2009
In this ERP study, linear and center-embedded musical sequences are built according to two artificial grammar types in language, named finite state grammar (FSG) and phrase structure grammar (PSG). The aim is to prove if neural sources and processing mechanisms for artificial grammar settings across domains are the same. Isochronous pitch sequences were constructed by two interval categories (3rd and 6th) in upward and downward direction. FSG sequences, which have the general form ABAB in artificial grammar, are translated into “small up/small down/large up/large down”. PSG sequences of form A[AB]B are transposed to “small up/large up/large down/small down”. In two ERP recordings testing FS…
Grosor coroideo en la retinosis pigmentaria
2013
La coroides como estructura vascular ocular, se encuentra implicada en la fisiopatología de diversas patologías oftalmológicas. Recientemente se ha observado que su espesor se encuentra alterado en diferentes enfermedades coriorretinianas, y además su flujo se encuentra reducido en la Retinosis Pigmentaria. Por lo que planteamos una tesis para el estudio del grosor coroideo en esta distrofia coriorretiniana. Los objetivos de la misma fueron determinar cuantitativamente el grosor coroideo mediante tomografía de coherencia óptica (Cirrus-HD-OCT®) en pacientes con Retinosis Pigmentaria y en sujetos sanos; y su posterior comparación entre ambos grupos. Secundariamente se analizó su posible corr…
Clinical anatomic, immunomorphologic and molecular anatomic data suggest interplay of thyroidal molecules, autoantibodies and Hsp60 in Hashimoto’s di…
2014
Hsp60 is, typically, a mitochondrial protein, but it also occurs in the cytosol, vesicles, and plasma membrane, and in the intercellular space and biological fluids, e.g., blood. Changes in the levels and distribution of Hsp60 are linked to several pathologies, including cancer and chronic inflammatory and autoimmune disorders. What is the histopathological pattern of Hsp60 in the thyroid of Hashimoto’s patients? Are there indications of a pathogenic role of Hsp60 that may make Hashimoto’s thyroiditis a chaperonopathy? Experiments reported here provide information regarding those questions. We found by various immunomorphological techniques increased levels of Hsp60 in the thyroid from HT p…
Standards for the diagnosis and management of complex regional pain syndrome: Results of a European Pain Federation task force.
2019
Background: Complex regional pain syndrome is a painful and disabling post-traumatic primary pain disorder. Acute and chronic complex regional pain syndrome (CRPS) are major clinical challenges. In Europe, progress is hampered by significant heterogeneity in clinical practice. We sought to establish standards for the diagnosis and management of CRPS. Methods: The European Pain Federation established a pan-European task force of experts in CRPS who followed a four-stage consensus challenge process to produce mandatory quality standards worded as grammatically imperative (must-do) statements. Results: We developed 17 standards in 8 areas of care. There are 2 standards in diagnosis, 1 in multi…
Glaucomatous Maculopathy: Thickness Differences on Inner and Outer Macular Layers between Ocular Hypertension and Early Primary Open-Angle Glaucoma U…
2020
The purpose of this study was to compare the thickness of all inner and outer macular layers between ocular hypertension (OHT) and early primary open-angle glaucoma (POAG) using spectral domain optical coherence tomography (SD-OCT) 8 × 8 posterior pole algorithm (8 × 8 PPA). Fifty-seven eyes of 57 OHT individuals and fifty-seven eyes of 57 early POAG patients were included. The thickness of macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform and nuclear layer, photoreceptor layer (PRL) and retinal pigment epithelium were obtained in 64 cells for each macular layer and mean thickness of superior and inf…
