New molecular data attest to the absence of cospeciation patterns between Placobdella costata (Fr. Müller, 1846) (Hirudinea) and freshwater turtles (…
2021
The only Palearctic representative of the leech genus Placobdella Blanchard, 1893 is P. costata, an ectoparasite of freshwater turtles. To date, no conclusive evidence about the possible presence of coevolutionary patterns between this leech and its turtle hosts is available due to the paucity of DNA sequence data available for P. costata; moreover, comparative host data is also mostly lacking, making any inferences more difficult. The discovery of new populations of the species in northern Italy and Sicily allowed us to generate novel mitochondrial DNA sequences and to compare the topology of the resulting phylogenetic trees with the phylogeny of the turtle hosts occurring in the study are…

IN-VITRO REGENERATION OF CALENDULA MARITIMA GUSS. (ASTERACEAE), A THREATENED PLANT ENDEMIC TO WESTERN SICILY
2016
Calendula maritima is a critically endangered endemic plant of Western Sicily. Besides habitat destruction, the hybridization with the contiguous congener species C. fulgida is a major threat to its conservation. For this reason, seed-based propagation and seed storage are not appropriate for conservation purposes. In the present paper we describe a rapid and prolific in vitro plant regeneration method by direct organogenesis from leaves of C. maritima. Leaf explants were cultured on solid Murashige and Skoog (MS) medium in the presence of several plant growth regulator combinations. The best shoot multiplication rate (2.5 shoots/explant) was obtained on the medium containing 4.4 µM 6-benzy…
Environmental quality assessment of the Sicilian coast using a multi-disciplinary approach
2018
A multidisciplinary approach for the assessment of the environmental quality of the Sicilian coast is presented. This approach can be adopted for any Mediterranean coastline. The territory was divided into elementary areas and for each of them we reported the most important taxa, belonging to fauna and vascular, bryophytic and algal flora, from a biogeographic point of view in order to evaluate punctual and general levels of biodiversity conservation. The comparative analysis showed that the main circumsicilian islands and the carbonate promontories of the Tyrrhenian coast present the highest degree of biodiversity. The coastal lagoons located in the south-eastern Sicily, even though charac…
Notulae to the Italian native vascular flora: 13
2022
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. Two new combinations are proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.

Limbal stem cells as a potential source of pancreatic beta cells
2009
BACKGROUND/RATIONAL Beta cell replacement therapy represents an alternative approach to conventional insulin regimen for the management of type 1 diabetes. Stem cells theoretically represent a suitable and renewable source of surrogate beta cells. Recently, it has been demonstrated that corneal epithelium contains stem cells in the basal layer of the limbus. Our aim was to isolate and characterize limbal stem cells (LSCs) from adult corneal-limbal biopsies, and to assess their capability to differentiate into insulin-producing cells. METHODS 2-3 mm2 biopsies were obtained from limbus and central cornea of four patients undergoing surgery for ocular diseases not involving conjuctive or corne…
