Oleanane-type glycosides from the roots of Weigela florida “rumba” and evaluation of their antibody recognition
2018
Three triterpene glycosides were isolated from the roots of Weigela florida "rumba" (Bunge) A. DC.: two previously undescribed 3-O-β-d-xylopyranosyl-(1→2)-[β-d-xylopyranosyl-(1→4)]-β-d-xylopyranosyl-(1→4)-β-d-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-l-arabinopyranosyloleanolic acid (1) and 3-O-β-d-xylopyranosyl-(1→2)-[β-d-glucopyranosyl-(1→4)]-β-d-xylopyranosyl-(1→4)-β-d-xylopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyloleanolic acid (2), and one isolated for the first time from a natural source 3-O-β-d-xylopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranosyloleanolic acid (3). Their structures were elucidated mainly by 2D NMR spectroscopic analysis (COSY, …
Artrite-Encefalite Caprina (CAEV) una patologia emergente nel territorio siciliano: programma volontario di eradicazione
2011
L’Artrite-Encefalite Virale Caprina è una malattia infettiva segnalata per la prima volta nel 1974; l’agente causale è stato isolato solamente nel 1979: si tratta di un virus della famiglia Retroviridae, genere Lentivirus. Il virus si diffonde principalmente attraverso colostro, latte (durante la mungitura) e, in minor misura, attraverso sangue, saliva, espettorato, secrezioni vaginali. La malattia può evolvere in forma subdola e tende ad essere sottostimata negli allevamenti infetti. Le forme cliniche negli animali adulti si presentano sotto forma di artrite e/o mastite, mentre negli animali giovani, nei quali l’evidenza è ancora più rara, si osserva sintomatologia clinica riferibile ad en…
Dual emission of a bis(pyrene)-functionalized, perbenzylated beta-cyclodextrin
2008
A bis(pyrene)-functionalized β-cyclodextrin (1) has been prepared in two steps from perbenzylated β-cyclodextrin. This compound shows dual emission properties, which arise from the pyrenyl chromophores. Upon excitation of 1 at 355 nm, monomer blue fluorescence (386, 407 and 428 nm) is observed in DMSO solution, whereas excimer green fluorescence (477 nm) is seen upon addition of ≥20 vol% water in DMSO. This suggests that modified β-cyclodextrin 1 changes its shape in response to the environment. The sensing properties of 1 towards carboxylic acids and alcohols were investigated in H2O–DMSO (80 : 20 v/v). Monomer fluorescence is restored selectively by medium length normal carboxylic acids, …
Polyphenols pattern and correlation with antioxidant activities of berries extracts from four different populations of SicilianSambucus nigraL.
2014
Sambucus nigra L. (Caprifoliaceae) is wide spread in temperate and sub-tropical zones. The consumption of its berries has been associated with health benefits especially for its high content of natural antioxidants such as polyphenols, in particular anthocyanins. In this work we investigated the polyphenolic composition and the in vitro antioxidant activities (ABTS, DPPH, BCB and FRAP-ferrozine (FRAP-FZ) assays) of S. nigra berries, collected in four different Sicilian areas (Italy). Elderberries are considered one of the fruits with highest anthocyanins content, the amount of phenolic compounds, other than anthocyanins, is approximately 1.5 times greater than the latter. The LC–MS analyses…

A method for measuring low-weight carboxylic acids from biosolid compost
2006
Concentration of low-weight carboxylic acids (LWCA) is one of the important parameters that should be taken into consideration when compost is applied as soil improver for plant cultivation, because high amounts of LWCA can be toxic to plants. The present work describes a method for analysis of LWCA in compost as a useful tool for monitoring compost quality and safety. The method was tested on compost samples of two different ages: 3 (immature) and 6 (mature) months old. Acids from compost samples were extracted at high pH, filtered, and freeze-dried. The dried sodium salts were derivatized with a sulfuric acid–methanol mixture and concentrations of 11 low-weight fatty acids (C1–C10) were a…
"La construction du personnage dans les derniers récits de Raffaele La Capria"
2018
C’est à la fin des années soixante-dix, au moment où d’anciens protagonistes des avant-gardes littéraires (comme Sollers en France ou Eco en Italie) renouent avec la fiction, que Raffaele La Capria, l’un des précurseurs dans la péninsule du roman expérimental, renonce définitivement au genre. Amore e Psiche, publié pour la première fois en 1973, fera l’objet de plusieurs remaniements sans que l’auteur en soit jamais satisfait. À partir des années quatre-vingt, La Capria ne publie plus que des...
<p><strong>Lectotypification of six names of species of <em>Scabiosa</em> s.l. (Caprifoliaceae) endemic to North Africa and r…
2020
As part of an ongoing project for the investigation of the Algerian-Tunisian flora, six names of species of Caprifoliaceae subfam. Dipsacaceae, endemic to central and western North Africa, described in the 19th and 20th Centuries under the genus Scabiosa, are here lectotypified. They are: Scabiosa camelorum Cosson & Durieu, Scabiosa cartenniana Pons & Quézel, Scabiosa daucoides Desf., Scabiosa farinosa Cosson, Scabiosa parielii Maire, and Scabiosa robertii Barratte. Taxonomic notes, distributisson and new unpublished data about plant phenology of these taxa are given.
Identification of SNPs in the promoter of β-lactoglobulin gene in three Sicilian goat breeds
2009
The aim of this work was to sequence the full-length promoter region of the caprine β-lactoglobulin (β-lg) gene in three Sicilian goat breeds (Girgentana, Maltese, and Derivata di Siria), in order to identify polymorphisms, to search for transcription factors (TFs) sites, and to check if polymorphisms found lay within TFs binding sites. The promoter region of β-lg gene in Sicilian goat breeds showed high level of polymorphism due to the presence of 31 SNPs. Binding sites for several TFs were found within the goat β-lg promoter and within regions conserved between ovine and caprine species. Two SNPs were detected within TFs binding sites, such as MPBF and NF-I. Further st…
Fingerprinting ofCaprinae ancient genomic DNA: A preliminary note for studying the history of domestication in sicily
1996
Oligonucleotide primers representing promoter and protein motifs in rats and mice were assayed for PCR amplification of ancient DNA from two sheep and one goat. We show preliminary evidence that this type of primers can be used for genomic fingerprinting of ancient DNA at interspecific level and can help in solving some paleoecological promlems.
