Comparative measurement of collagen bundle orientation by Fourier analysis and semiquantitative evaluation: reliability and agreement in Masson's tri…
2017
Summary Measurement of collagen bundle orientation in histopathological samples is a widely used and useful technique in many research and clinical scenarios. Fourier analysis is the preferred method for performing this measurement, but the most appropriate staining and microscopy technique remains unclear. Some authors advocate the use of Haematoxylin-Eosin (H&E) and confocal microscopy, but there are no studies comparing this technique with other classical collagen stainings. In our study, 46 human skin samples were collected, processed for histological analysis and stained with Masson's trichrome, Picrosirius red and H&E. Five microphotographs of the reticular dermis were taken with a 20…
Age-related dermal collagen changes during development, maturation and ageing - a morphometric and comparative study.
2014
The tissue organisation of dermal collagen is gaining importance as a contributing factor both in development and ageing, as well as in skin maturation processes. In this work we aim to study different representative parameters of this structural organisation in 45 human skin samples of assorted ages, by means of image analysis. The variation of these parameters on the basis of age was assessed using several regression models (linear, quadratic and cubic). The area occupied by collagen was significantly reduced as a function of age in the papillary dermis (R(2) = 0.437, P < 0.0001), as well as the thickness of the collagen bundles (R(2) = 0.461, P < 0.0001), following statistical models of …
Dyke-Davidoff-Masson syndrome: case report of fetal unilateral ventriculomegaly and hypoplastic left middle cerebral artery
2013
Prenatal ultrasonographic detection of unilateral cerebral ventriculomegaly arises suspicion of pathological condition related to cerebrospinal fluid flow obstruction or cerebral parenchimal pathology. Dyke-Davidoff-Masson syndrome is a rare condition characterized by cerebral hemiatrophy, calvarial thickening, skull and facial asymmetry, contralateral hemiparesis, cognitive impairment and seizures. Congenital and acquired types are recognized and have been described, mainly in late childhood, adolescence and adult ages. We describe a female infant with prenatal diagnosis of unilateral left ventriculomegaly in which early brain MRI and contrast enhanced-MRI angiography, showed cerebral left…

Identification to cardiac conduction cells in humans and pigs according to their zonal distribution, using histological, immunohistochemical and morp…
2021
Abstract Histologically, the cardiac conduction network is formed of electrically isolated subendocardial fibers that comprise specialized cells with fewer myofibrils and mitochondria than cardiomyocytes. Our aim is to uncover regional variations of cardiac conduction fibers through histological and morphometric study in a porcine and human model. We analyzed five male adult human hearts and five male pig hearts. The left ventricles were dissected and sectioned in the axial plane into three parts: basal, middle third and apex regions. Cardiac conduction fibers study was carried out using hematoxylin-eosin and Masson's trichrome staining, and cardiac conduction cells and their junctions were…
Recensione: André Breton, Il surrealismo e la pittura, Abscondita, Milano 2010, in Rivista di studi filosofici "Syzetesis", febbraio/2011, http://www…
2011
La vicenda editoriale del saggio Il surrealismo e la pittura ripercorre in parte la biografia intellettuale di André Breton: la prima edizione del 1928, uscita per i tipi di Gallimard, è frutto di un assemblaggio di articoli che Breton pubblica sulla rivista «La Révolution surréaliste» dal luglio 1925 all'ottobre 1927. A questa prima, seguiranno altre due edizioni riviste e ampliate dallo stesso Breton: Le surréalisme et la peinture suivi de Genèse et perspective artistique du surréalisme et de fragments inédits, Brentano's, New York 1945; Le surréalisme et la peinture, Paris, Gallimard 1965 (ripubblicato recentemente nelle Œuvres complètes IV, a cura di M. Bonnet, Paris, Gallimard 2008). Q…

Use of decellularized tracheas for airways engineering
2016
Background/Objective: Tracheal stenosis produces serious dyspnea. In some cases, a defective correction or timely intervention can lead to the death of the patient. The Hospital Clinico Universitario de Valencia is a reference hospital for the treatment of patients with airway problems exhibiting complex tracheal stenosis. Surgery is limited to a maximum length of 6-7 cm and it is not exempt of mortality (3-5%). In this study we have study the useful of decellularized porcine tracheas to be used in airway regenerative medicine. Methods: Three porcine tracheas were cut in 3 cm rings and exposed to SDS 2% for up to four weeks. Cell content was evaluated by fluorescence microscopy (DAPI) weekl…
