Palaeophylloxera nov. gen., The firstfossil specimen of the family Phylloxeridae (Hemiptera, Phylloxeroidea); Lower Miocene of Spain
1999
A fossil alate aphid from the Lower Aragonian (Lower Miocene) deposits of Rubielos de Mora (Teruelprovince) in eastern Spain is described as Palaeophylloxera seilacheri nov. gen. and sp. It is the first fossil specimen described within the Family Phylloxeridae. The principal differences between this genus and other representatives of the Phylloxeridae (and also the extinct Elektraphididae) are the apparent presence of an oblique vein on the hind wing, the presence of distinctly visible transverse striae on antennal segment III, and the peculier venation on the fore wings.
Eficacia y cambios anatómicos inducidos por los dispositivos de avance mandibular en pacientes con síndrome de apnea-hipopnea del sueño (SAHS).
2016
Los dispositivos de avance mandibular (DAM) se consideran la primera elección terapéutica en pacientes con síndrome de apnea-hipopnea del sueño (SAHS) leve o moderada y en SAHS severos que no toleren o rechacen otras opciones de tratamiento. Sin embargo, todavía existen cuestiones por resolver acerca de la utilización de los DAM como el lugar y el modo de acción exactos, o identificar aquellos pacientes que pueden tener un resultado satisfactorio a través de la selección de varios factores predictivos, o saber porqué en el paciente SAHS severo el dispositivo de avance mandibular no es siempre un tratamiento eficaz. Objetivos: Determinar los cambios morfológicos en la vía aérea superior (VAS…
The role of the styloid apophysis of the temporal bone in the biomechanics of the tongue, mandible, hyoid system: A case study
2020
Temporomandibular disorders are characterized by ear pain, tinnitus, difficulty in chewing, dysphagia and also dizziness, cervical limitation of range of movement (ROM) and other less common disorders. Numerous recent studies associate the presence of these signs and symptoms with an elongated styloid apophysis, as in the case of Eagle syndrome. The purpose of this clinical case is to support the thesis of a common syndrome that temporomandibular joint (TMJ) disorders with an elongated styloid process affirming the relationship between temporal bone, mandibule, hyoid bone and tongue. The patient was a 57-year-old woman who reported having ear algia and tinnitus all on the right side with di…
Sympathetic tone and ventricular tachycardia
2008
Background The pathogenesis of idiopathic monomorphic ventricular tachycardia is not clear. We suppose that a lack of balance of the sympathetic system could be involved. Frequency domain analyses of the heart rate can be useful to understand autonomic system balance. Therefore we performed this evaluation on a sample of seven children affected by idiopathic monomorphic ventricular tachycardia. Methods and results We performed a Holter recording for palpitations on all the children, with an average age of 12 (range: 7-18 years). In all the patients many episodes of repeated sustained or nonsustained ventricular tachycardia were demonstrated, with an average heart rate of 170 bpm. We exclude…
The "Neurocentric" Approach to Essential Hypertension: How Reliable is the Paradigm of Hyperkinetic Hypertension? A Focus on the Sympathetic Nervous …
2017
BACKGROUND: Clinic resting heart rate (RHR), is one of the cardiovascular parameters more easily measurable. In the general population RHR has been associated with total and cardiovascular mortality and higher rate of vascular events. OBJECTIVE: The case of essential hypertension is in some ways peculiar: in the past decades has often been attributed to hypertensive subjects higher values of RHR than healthy controls as a result of the effects of the different factors leading to the development of essential hypertension itself, first of all the presence of an increased tone of the sympathetic nervous system Methods: Several excellent articles debated the issue of autonomic dysfunction in es…
Plywood Jig—A New Technique for Root Canal Curvature Measurement
2021
The successful outcome of endodontic treatment is dependent on complete cleaning, shaping as well as three dimensional obturation of the root canal system. A conventional radiograph is a two-dimensional replication of a three-dimensional object and does not provide any conclusive evidence for canal curvatures. An accurate knowledge of the tooth anatomy and curvature is essential to avoid procedural errors. 100 freshly extracted human teeth were used in this study. Digital images were obtained using the plywood JIG and Schneider’s technique. These images were analyzed using the VixWin Pro digital image analyzing software (Gendex system). Statistical analysis was done using paired t test. The…
The use of tricyclic antidepressants in the treatment of temporomandibular joint disorders: systematic review of the literature of the last 20 years
2009
Many therapies have been proposed for the management of temporomandibular disorders, including the use of different drugs. However, lack of knowledge about the mechanisms behind the pain associated with this pathology, and the fact that the studies carried out so far use highly disparate patient selection criteria, mean that results on the effectiveness of the different medications are inconclusive. This study makes a systematic review of the literature published on the use of tricyclic antidepressants for the treatment of temporomandibular disorders, using the SORT criteria (Strength of recommendation taxonomy) to consider the level of scientific evidence of the different studies. Followin…
Tratamiento de la anquilosis de la articulación temporomandibular por artroplastia simple
2006
Objetivo: El propósito de este trabajo es mostrar que la artroplastia simple mejora la apertura bucal al tratar la anquilosis temporomandibular. Pacientes y métodos: Fueron tratados ocho pacientes con anquilosis de la articulación temporomandibular por medio de artroplastia simple. Los pacientes fueron evaluados en el postoperatorio por un periodo por lo menos de veinticuatro meses (mínimo 24 y máximo 48 meses). Resultados: De los ocho pacientes (once articulaciones), cinco (62,5%) presentaron afectación unilateral y tres pacientes (37.5%) afectación bilateral de la ATM. La edad media fue de 20 años ± 9 (rango de 3 a 30 años). La máxima apertura bucal en el período preoperatorio fue de 9,25…
Modeling Vestibular Compensation: Neural Plasticity Upon Thalamic Lesion.
2020
The present study in rats was conducted to identify brain regions affected by the interruption of vestibular transmission and to explore selected aspects of their functional connections. We analyzed, by positron emission tomography (PET), the regional cerebral glucose metabolism (rCGM) of cortical, and subcortical cerebral regions processing vestibular signals after an experimental lesion of the left laterodorsal thalamic nucleus, a relay station for vestibular input en route to the cortical circuitry. PET scans upon galvanic vestibular stimulation (GVS) were conducted in each animal prior to lesion and at post-lesion days (PLD) 1, 3, 7, and 20, and voxel-wise statistical analysis of rCGM a…
La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…
2013
La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…
