Damipipecolin and damituricin, novel bioactive bromopyrrole alkaloids from the Mediterranean sponge Axinella damicornis

2007

Two new bromopyrrole alkaloids, damipipecolin (1) and damituricin (2), have been isolated from the Mediterranean sponge Axinella damicornis, and their structures established through spectroscopic methods. Compounds 1 and 2 extend the structural variety of the so far known pyrrole alkaloids; in these compounds, the 4-bromopyrrole 2-carboxylic acid is directly condensed with a non-protein cyclic alpha-amino acid, the (2R, 4R)-trans-4-hydroxypipecolic acid and (2R, 4R)-cis-N,N'-dimethyl-4-hydroxyproline (D-turicine) in 1 and 2, respectively. Compounds 1 and 2 were found to display a modulating effect of the serotonin receptor activity in vitro.

Torilis pseudonodosa Bianca (Apiaceae) – new species for the flora of Ukraine

2022

We report the first record of Torilis pseudonodosa Bianca (Apiaceae) from Ukraine. It was found on 28th of May 2021 in the “Potiivska” section of the Black Sea Biosphere Reserve near the village of Zaliznyi Port (Southern Ukraine). Torilis pseudonodosa previously was known from various countries in the Mediterranean Basin and Western Asia, but not from Ukraine nor elsewhere in Eastern Europe. We discovered a hitherto unknown population of Torilis pseudonodosa during the 15th EDGG Field Workshop, an international expedition of the Eurasian Dry Grassland Group (EDGG) taking place in Southern Ukraine, from 23 May to 2 June 2021. We present the taxon, its morphology and general distribution, de…

Presence of ochratoxin A (OTA) mycotoxin in alcoholic drinks from southern European countries: wine and beer.

2014

The main filamentous fungi producers of mycotoxins are Aspergillus spp., Penicillium spp., and Fusarium spp. Their effect can provoke a broad range of toxic properties including carcinogenicity and neurotoxicity, as well as reproductive and developmental toxicities. Ochratoxin A (OTA) is produced by Aspergillus and Penicillium spp. The purpose of this review was to evaluate the risk assessment of OTA in alcoholic drinks (beer and wine) by compiling the results obtained from studies and reviews related to the presence of OTA in these two drinks from southern European countries in the period 2005–2013 and comparing those results with the legislation available in the European Union.

Serum 25-hydroxyvitamin D levels in patients with cutaneous lupus erythematosus in a Mediterranean region

2010

Low vitamin D levels have been found in patients with autoimmune diseases, including type I diabetes, rheumatoid arthritis, multiple sclerosis and systemic lupus erythematosus. The main source of vitamin D is exposure to sunlight, but the same solar radiation is known to exacerbate lupus erythematosus. We investigated the prevalence of vitamin D insufficiency in patients with cutaneous lupus erythematosus (CLE). We designed a cross-sectional study including 55 patients with CLE to measure their serum 25-hydroxyvitamin D (25(OH)D) by chemiluminescence immunoassay and compare it with a control group consisting of 37 healthy sex and age-matched subjects recruited from the patients' relatives a…

SNP genotyping elucidates the genetic diversity of Magna Graecia grapevine germplasm and its historical origin and dissemination

2019

Background: Magna Graecia is the ancient name for the modern geopolitical region of South Italy extensively populated by Greek colonizers, shown by archeological and historical evidence to be the oldest wine growing region of Italy, crucial for the spread of specialized viticulture around Mediterranean shores. Here, the genetic diversity of Magna Graecia grape germplasm was assessed and its role in grapevine propagation around the Mediterranean basin was underlined. Results: A large collection of grapevines from Magna Graecia was compared with germplasm from Georgia to the Iberian Peninsula using the 18 K SNP array. A high level of genetic diversity of the analyzed germplasm was determined;…

Morphological variability in and distributional data on phaleria bimaculata populations from islands of the central mediterranean area

2011

This study aimed to collect new taxonomic and distribution data on Phaleria bimaculata (L.) (Coleoptera Tenebrionidae) from Sicily (southern Italy), the circum-Sicilian islands and the Maltese archipelago. Particular attention was paid to the diagnostic morphological features observed in the populations sampled, focusing on the subspecies Phaleria bimaculata marcuzzii Aliquò. P. bimaculata individuals were collected from 20 different locations, of which 2 were located in the Sicilian mainland, 9 in circum-Sicilian islands and 9 in the Maltese Islands. In addition, four Phaleria acuminata Kuster populations were also recorded along southern Sicilian shores. The two Phaleria species were neve…

The Sicilian taxa of Genista sect. Voglera and their phytosociological framework

2012

The phytosociological role of taxa of Genista sect. Voglera in the vegetation context of Sicily is here examined. It was carried out on plant communities characterised by the Sicilian endemics G. aristata, G. madoniensis and G. cupanii. These taxa and their floristic settlement have been examined from the biogeographical point of view. Basing on our results, the popu- lations of G. madoniensis are to be referred to a new association named Cisto salvifolii- Genistetum madoniensis, ascribed to the class Cisto-Lavanduletea. Multivariate analysis shows a clear ecological differentiation of G. madoniensis with respect to the other Sicilian species. Instead, its habitus and ecology are closer to …

Health status, diseases and vaccinations of the homeless in the city of Palermo, Italy.

2018

Introduzione. Un tempo "barboni", oggi senzatetto, il loro numero sta aumentando considerevolmente negli ultimi anni. Molti di loro soffrono di malattie croniche, problemi di salute mentale, dipendenze e necessitano di cure mediche complesse. Il loro stato di salute è spesso esacerbato per maggiori difficoltà nell'accesso alle cure primarie rispetto alla popolazione generale. Materiali e Metodi. È stato distribuito un questionario autosomministrato al fine di valutare le condizioni di salute dei senzatetto che vivono a Palermo. È stato utilizzato un modello di regressione logistica multivariata calcolando gli Odds Ratios aggiustati (aOR). Risultati. Il campione è costituito da 52 senzatetto…
