Isomotiol, a new triterpene from strychnos potatorum

1978

Isomotiol (fern-8-en-3β-ol) was isolated from the leaves of Strychnos potatorum; it was not known previously as a natural product, but it has been obtained by acidic isomerization of compounds with a fern-7-ene or a fern-9(11)-ene skeleton. From the leaves and the bark mixtures of sitosterol, stigmasterol and campesterol were also isolated.

Sterol stability in functional fruit beverages enriched with different plant sterol sources

2012

Abstract Two different plant sterol (PS) sources (free PS from tall oil and esterified PS from vegetable oils) were used for manufacturing two types of functional beverages (fruit and milk-based fruit beverages), and their PS and phytosterol oxidation product (POP) contents were determined. Gas chromatography–tandem mass spectrometry (GC–MS/MS) was used for identification and gas chromatography–flame ionization detection (GC–FID) for quantitation purposes. Brassicasterol, campesterol, campestanol, stigmasterol, β-sitosterol and sitostanol were the quantified PS, conforming a profile in order with current legislation. The relative percentages of PS differed according to the enrichment source…

Differential antiepileptic effects of the organic calcium antagonists verapamil and flunarizine in neurons of organotypic neocortical explants from n…

1988

Effects of the organic calcium antagonists verapamil and flunarizine on pentylenetetrazol induced paroxysmal depolarizations were tested in organotypic neocortical explants taken from neonatal rats. In these in vitro experiments the papaverin derivative verapamil depressed, and finally abolished, epileptic discharges in all cases. The piperazine derivative flunarizine, however, which is known to suppress epileptic discharges in hippocampal CA3 neurons (Bingmann and Speckmann 1986), showed no significant antiepileptic effects in the explanted neocortical neurons. Thus, the present findings may indicate that the suppressive action of flunarizine on the generation of paroxysmal depolarizations…

Bell Beakers in the southeast of France. From Archaeology to History of the third millenium BC

2002

The term "Bell Beaker", in the strict sense, designates a ceramic beaker form with an S-shaped profile that gives it the shape of an inverted bell. This type of drinking-vessel is characterized by both its very particular pattern of decoration and by the generally skilled execution of that decoration. By extension, the decoration characteristic of these beakers bas allowed the expansion of the category "Bell-Beaker" to include other pottery forms and even other types of decoration showing the same tradition, vvhich probably represent an evolution or reproduction of the original Bell Beaker pattern, The recognition of these objects and their definition as a class date to the nineteenth centu…

Nuove relazioni tra tessuto urbano e agricolo nel parco del Gugliotta a Piano Tavola, Carini

2014

To the south-west of Palermo, along the north-east belt of Carini marked by Mount Colombrina and crossed by thestream Gugliotta, a wide area called Piano Tavola stretches between city and countryside. Its margins are given by the suburban volumes standing along corso Italia (west), the olive grove under Pizzo Castellaccio (east), villa Dominici (north-east), the industrial area and the railway (north), and the quarry in Manostalla locality (south-east). It is evident the pressure of the buildings on the olive grove and countryside, the presence of roads that close and isolate the district, and the lack of continuity between open spaces and built areas. The reorganization of the road network…

Abitare in estensione

2014

Il saggio “Abitare in estensione” costituisce un’articolata premessa ai diversi contributi presenti nel volume esito delle attività dell’Unità di ricerca della Facoltà di Architettura di Palermo del Prin 2009 dal titolo Dalla campagna urbanizzata alla “città in estensione”: le norme compositive dell’architettura del territorio dei centri minori (Coordinatore nazionale Prof. Lugi Ramazzotti, responsabile dell’UDR locale Prof. Andrea Sciascia). Dalla stesura del modello B alla pubblicazione finale del Prin trascorrono in media tre anni. Anzi, qualche mese in meno, in considerazione dei tempi sempre più brevi imposti dalle nuove norme che regolano la rendicontazione finale. Durante questo peri…

Valenze etiche dell'opposizione città-campagna tra commedia plautina ed elegia augustea

2005

Nella commedia latina, all’interno della contrapposizione spaziale campagna-città, quest’ultima rappresenta il luogo del vizio e dell’inganno legati alla relazione adulterina, in piena conformità con l’immagine tradizionale romana della campagna come luogo delle virtù quiritarie. L’innamorato comico, dunque, condivide con il poeta-amante elegiaco lo spazio che, in perfetta sintonia con la tradizione letteraria, la stessa mentalità romana assegnava all’amore adulterino: la città. Ma, rispetto alla netta condanna etica dell’ambiente urbano che riscontriamo nella commedia, la rappresentazione elegiaca della città è ben più complessa, ed oscilla tra una rappresentazione ‘tradizionale’ di impost…

Infrastrutture e paesaggio nella "città in estensione"

2017

L’esperienza didattica e di ricerca presentata nel saggio prende le mosse dall’attivazione di un laboratorio di laurea magistrale in Progettazione Architettonica diretto dal prof. Palazzotto e sviluppato nell’ambito del corso di laurea in Architettura dell’omonimo Dipartimento presso l’Università degli Studi di Palermo. Il laboratorio ha visto la partecipazione complessiva di 11 laureandi, che hanno esitato le proprie tesi negli anni compresi tra il 2013 e il 2015. Il laboratorio di laurea, facendo propria l’idea di “città-campagna” avanzata da Giuseppe Samonà nel 1976 – che porta con sé un esplicito riferimento a identità formali e spaziali specifiche intese a conferire allʼambito della ca…

Neuronal Growth and Behavioral Alterations in Mice Deficient for the Psychiatric Disease-Associated Negr1 Gene

2018

Neuronal growth regulator 1 (NEGR1), a member of the immunoglobulin superfamily cell adhesion molecule subgroup IgLON, has been implicated in neuronal growth and connectivity. In addition, genetic variants in or near the NEGR1 locus have been associated with obesity and more recently with learning difficulties, intellectual disability and psychiatric disorders. However, experimental evidence is lacking to support a possible link between NEGR1, neuronal growth and behavioral abnormalities. Initial expression analysis of NEGR1 mRNA in C57Bl/6 wildtype (WT) mice by in situ hybridization demonstrated marked expression in the entorhinal cortex (EC) and dentate granule cells. In co-cultures of co…
