Somatosensory evoked potentials in Arnold-Chiari malformation.
2002
Abstract Nearly all patients with repaired myelomeningoceles have an Arnold–Chiari (AC) malformation and about 20% of these patients develop clinical signs of brainstem dysfunction. The management of symptomatic AC malformation is still controversial and techniques are needed to provide an objective assessment of brainstem function. We recorded somatosensory evoked potentials (SEPs) in 52 patients aged between 8 months and 20 years (median 7.3 years) with AC malformation, to determine whether the SEPs discriminate patients with symptomatic AC malformation from those without symptoms. The subcortical far-field components P13, P14 and N18, which are generated within the brainstem, were record…
Cerebral and spinal MR-findings in patients with postrepair myelomeningocele
1990
In 114 patients with postrepair myelomeningocele MRI of the spine was performed. Tethered cord (89%) and associated malformations (syrinx, lipoma etc.) (33%) were the most important findings. Additional MRI scans of the head (44 patients) revealed numerous further anomalies. Arnold Chiari malformation was found in 76% of the patients (ACM I: 32%, ACM II: 44%). In the ACM II group compression of lower cranial nerves, brain stem, and cerebellum can lead to considerable neurologic symptoms. Therefore in patients with progressive neurologic dysfunction a complete investigation of the whole spine and brain is necessary. MRI proves to be the diagnostic procedure of choice in patients with dysraph…
Adultescenti e giovani adulti. Aspetti educativi della famiglia “lunga”
2019
The essay starts as a reflection about the changes of the transition to adulthood in contemporary life, it is a presentation focusing on the issue of identity construction in relation to the structural variables that condition the lifestyle of the young adult and their relationship with the family of origin. The adult’s task is a generative task aimed to increase and develop the next generation; therefore, we speak about a task that delineates itself as essentially educational. However, the discussion allows to see an education requirement/emergency that is not only young people but also adults; there is a priority to educate the adult society to take and rewrite their generative role.
A combined electrophysiological and morphological examination of episodic memory decline in amnestic mild cognitive impairment.
2013
Early stages of Alzheimer’s disease (AD) are characterized by neuropathological changes within the medial temporal lobe cortex (MTLC), which lead to characteristic impairments in episodic memory, i.e., amnestic mild cognitive impairment (aMCI). Here, we tested the neural correlates of this memory impairment using event-related potentials (ERPs) and voxel-based morphometry. Twenty-four participants were instructed to encode lists of words and were tested in a yes/no recognition memory task. The dual-process model of recognition memory dissociates between acontextual familiarity and recollection of contextual details. The early frontal ERP old/new-effect, which is thought to represent a neura…
LA CREAZIONE DI SCUOLE PER GENITORI NELLE ISTITUZIONI PUBBLICHE
2013
L’Unità di ricerca di Pedagogia generale e sociale del Dipartimento di psicologia e di scienze dell’educazione dell’Università di Palermo, d’intesa con le cattedre di Pedagogia della famiglia e di Educazione degli adulti della Facoltà di Scienze della formazione e col supporto logistico e organizzativo dell’Associazione Italiana Maestri Cattolici della Regione Sicilia, ha condotto negli anni scolastici 2010/2011 e 2011/2012, un percorso di formazione di insegnanti animatori di educazione familiare. Ci si è avvalsi della collaborazione del Centro studi pedagogici sulla vita matrimoniale e familiare, istituzione di eccellenza della sede bresciana dell’Università Cattolica del Sacro Cuore, dir…
Amnesia and the hippocampus
2006
PURPOSE OF REVIEW: Long-term memory impairments have great medical significance and a considerable health and economic burden. Understanding their cognitive and neuroanatomical underpinnings is of crucial importance. Severe amnesia is usually observed following bilateral hippocampal pathology. This review addresses the precise role of the hippocampus and related medial temporal lobe structures in amnesia. RECENT FINDINGS: Disagreements exist over whether, following selective hippocampal damage: retrograde amnesia for episodic memories is temporally limited or extensive and ungraded; anterograde amnesia involves both recollective and familiarity processes. It is accepted that material specif…
Phytochemical profile and antioxidative properties of Plinia trunciflora fruits: A new source of nutraceuticals.
2020
Abstract This study evaluated the polyphenol profile and the antioxidative properties of Plinia trunciflora (O. Berg) Kausel fruits. Folin-Ciocalteau and pH-jumping methods indicated that these berries are a major source of antioxidant polyphenols (1201.05 mg GAE/100 g FW), particularly anthocyanins. HPLC-DAD-ESI-MS/MS analysis identified cyanidine glycosides as the main components. Flavon-3-ols and hydrolysable-tannins were also found. CAA assay showed that extracts of P. trunciflora fruits prevent lipid peroxidation in HepG2 cells with higher efficacy than other colourful fruits (CAA50 935.25 mg FW/mL cell medium). Moreover, our results suggested that the observed antioxidant protection i…
Otra visión de la historia del mueble. La evolución técnica, base de la formal
2008
La evolución del mobiliario no sólo está condicionada por la transformación en los estilos de vida, sino también por el desarrollo de técnicas de elaboración de la madera. Este artículo está dirigido a aquellos que investigan o se aproximan al mobiliario y las artes decorativas, con la intención de proporcionar una herramienta para la comprensión de la evolución constructiva y de las técnicas decorativas.

Herbicidal potential of aqueous extracts from Melia azedarach L., Artemisia arborescens L., Rhus coriaria L. and Lantana camara L.
2017
In the search for new strategies for weed management in agricultural systems, a great interest is to use the plant extracts to replace or integrate, chemical weed control. Two experiments were done to test the effects of plant water extracts from Chinaberry (Melia azedarach L.), Tree Wormwood (Artemisia arborescens (Vaill.) L.), Sicilian Sumac (Rhus coriaria L.) and Lantana (Lantana camara L.) on seed germination of Rocket (Eruca sativa Mill.), Rapeseed (Brassica napus L.), Bladderflower (Araujia sericifera Brot.) and Psyllium (Plantago psyllium L). The water extracts (pure and 50% mixtures) from the donor species were applied on seeds of recipient plants. In second experiment in pots, thes…
Una committenza nobile in Sicilia tra Cinque e Seicento. Le architetture dei Branciforte di Raccuja (1552-1661)
2014
Oggetto di studio della tesi sono i programmi costruttivi avviati tra il Cinque e il Seicento dal casato dei Branciforte di Raccuja. In particolare la tesi affronta lo studio delle architetture fondate da Nicolò Placido Branciforte nel corso del Seicento: il palazzo di famiglia a Palermo e il castello di Leonforte. I programmi costruttivi sono stati analizzati in relazione al cursus honorum, alla politica economica e culturale del casato e posti a confronto con gli omologhi interventi edificatori intrapresi da pari e sodali, secondo una metodologia conoscitiva auspicata da studi precedenti e non ancora messa in atto in Sicilia. In this thesis we study the architectural programs initiated by…
