Predicting the working alliance over the course of long-term psychodynamic psychotherapy with the Rorschach Ego Impairment Index, self-reported defen…
2021
Better therapeutic alliances are known to predict better treatment outcomes, but little knowledge still exists on the patient characteristics that lead to better alliances. In a sample of 128 outpatients assigned to long-term psychodynamic psychotherapy and suffering from mood and/or anxiety disorder, this study evaluated how the alliance, measured using the Working Alliance Inventory (WAI), is predicted by three different measures for assessing psychological resources and vulnerabilities: the Wechsler Adult Intelligence Scale—Revised (WAIS–R), the Defense Style Questionnaire (DSQ), and the Rorschach-based Ego Impairment Index (EII-2). All the three measures showed some ability to predict t…
Absence Seizure Detection Algorithm for Portable EEG Devices
2021
Absence seizures are generalized nonmotor epileptic seizures with abrupt onset and termination. Transient impairment of consciousness and spike-slow wave discharges (SWDs) in EEG are their characteristic manifestations. This type of seizure is severe in two common pediatric syndromes: childhood (CAE) and juvenile (JAE) absence epilepsy. The appearance of low-cost, portable EEG devices has paved the way for long-term, remote monitoring of CAE and JAE patients. The potential benefits of this kind of monitoring include facilitating diagnosis, personalized drug titration, and determining the duration of pharmacotherapy. Herein, we present a novel absence detection algorithm based on the propert…
T-wave alternans analysis improvement by means of curve alignment prior to distance calculation.
2007
Tracking of repolarization instabilities in the ECG, such as T-wave alternans (TWA), has become a popular non-invasive method to assess the vulnerability to malignant arrhythmic events. These instabilities are usually characterized by small amplitude changes and their measurement is difficult due to the presence of noise and artifacts. Several methods have been recently proposed to address this problem. Most of them are based on amplitude analysis of beat-to-beat alternation of the T wave. This paper describes a preprocessing stage intended to be used prior to amplitude analysis and aimed at improving the alignment between consecutive T waves. This increases the accuracy of the difference c…
IL-6 stimulates annexin 1 expression and translocation and suggests a new biological role as class II acute phase protein.
1998
Annexin 1 (Ax 1), a protein whose synthesis and secretion are induced during the inflammatory response, has been proposed as a mediator of the anti-inflammatory action of glucocorticoids. To gain insight into a broader role of Ax 1 during the inflammatory response, the authors have investigated how pro-inflammatory cytokines [interleukin 1 (IL-1), IL-6 and tumour necrosis factor alpha (TNF-alpha)] affect Ax 1 expression and regulation at transcriptional and translational levels. The authors show that induction of the Ax 1 protein and its translocation to the cell membrane are stimulated by interleukin 6. However neither IL-1 nor TNF-alpha display these effects. Analysis of 5'-deletion mutan…
Sea urchin HSF activity in vitro and in transgenic embryos.
1997
Evidence is provided for the presence at the physiological temperature of 20 degrees C of a heat shock transcriptor factor, HSF, in the nuclei of P.lividus embryos. This HSF is able to specifically bind in vitro the heat shock element, HSE, of the promoter of the hsp70 gene i.v., as suggested by DNA-protein binding reactions and DNAse I protection assays. Upon heat-shock, at the temperature of 31 degrees C, its ability to bind the HSE units becomes much higher. The HSF activated by heat-shock drives in vivo the transcription of the beta-galactosidase reporter gene in transgenic sea urchin gastrulae. An ATF-like transcription factor, widely described in other organisms but not at all in sea …
In silico characterization of the neural alpha tubulin gene promoter of the sea urchin embryo Paracentrotus lividus by phylogenetic footprinting
2011
During Paracentrotus lividus sea urchin embryo development one alpha and one beta tubulin genes are expressed specifically in the neural cells and they are early end output of the gene regulatory network that specifies the neural commitment. In this paper we have used a comparative genomics approach to identify con- served regulatory elements in the P. lividus neural alpha tubulin gene. To this purpose, we have first isolated a genomic clone containing the entire gene plus 4.5 Kb of 5 0 upstream sequences. Then, we have shown by gene transfer experiments that its non-coding region drives the spatio- temporal gene expression corresponding substantially to that of the endogenous gene. In addi…
Atypical posterior circulation strokes: a case-based review of rare anatomical variations involved
2021
The circle of Willis is a very important vascular mechanism of protecting against cerebral ischemia, especially when circulation within the main arteries irrigating the brain is somehow impeded. As result of congenital malformation arising early in embryonic development, the fetal-type posterior circle of Willis remains as such during the rest of one's life. Consequently, the posterior cerebral artery (PCA) becomes a branch of the internal carotid artery (ICA), rather than of the basilar artery (BA). Furthermore, the rest of collateral circulation, between the anterior and the posterior regions of the brain, is also negatively affected (e.g., leptomeningeal vessels). The anatomical variant …
Chameleonic appearance of caseous calcification of the mitral valve – still a problem for its appropriate management
2021
According to the research literature, the caseous calcification of the mitral annulus (CCMA) is a rare variant of the mitral annulus calcification (MAC) entity, described mostly in elderly women. The aim of this study was to present the case of a 53-year-old female patient with caseous calcification of the mitral valve annulus and posterior cusp, which was diagnosed as papillary fibroelastoma. An echo-dense and quasi-homogeneous tumoral mass, measuring 1.6/1.4 cm, at the level of the posterior mitral ring was detected by echocardiographic examination, as well as by cardiac magnetic resonance imaging (MRI). Histopathological analysis revealed fibrous connective tissue with myxoid areas, hyal…
The Italian adaptation and validation of the Adult Sibling Relationship Questionnaire (ASRQ) in Italian emerging adults
2013
The aims of the present study were to provide a contribution to the validation of the Adult Sibling Relationship Questionnaire (ASRQ) (Stocker, Lanthier, & Furman, 1997) with a population of Italian emerging adults. The ASRQ measures individuals’ current perceptions of their own behaviour and feelings toward their sibling, as well as their perceptions of their sibling’s behaviour and feelings toward him or her by assessing fourteen fundamental dimensions (Intimacy; Affection; Emotional Support; Instrumental Support; Knowledge; Similarity; Admiration; Acceptance; Dominance; Competition; Antagonism; Quarrelling; Maternal Rivalry; and Paternal Rivalry), combined in order to form three macro-di…
Psychometric properties of the emotional awareness questionnaire in a Spanish child population
2016
La competencia emocional es la capacidad para percibir, expresar, comprender, regular y controlar nuestras emociones y las de los demás. La conciencia emocional es la competencia básica que permite el desarrollo del resto de competencias emocionales durante la infancia y la adolescencia. En este trabajo, se han estudiado las propiedades psicométricas de la versión española del Cuestionario de conciencia emocional, administrado a 1476 niños/as españoles (8-12 años). Se ha replicado la estructura original formada por seis factores. Se han estudiado la Habilidad de los ítems y del instrumento, la validez de constructo, de contenido y concurrente, los resultados han sido satisfactorios. Se han …
