Recent and new taxonomic acquisitions in some native genera of Asteraceae from southern Italy and Sicily
2021
After a brief review of the recent acquisition in some native genera of family Asteraceae from southern Italy and Sicily, a new endemic species of Anthemis (sect. Hiorthia) is described from Sicily and named Anthemis parlatoreana. The locus classicus of the new taxon, falling in the NW Tyrrhenian coast of the island (Castellammare del Golfo, Trapani), coincides with that of Ptilostemon greuteri, another endemic very rare species of the Sicilian flora. Data on the morphology, distribution, ecology and conservation status of the new species are provided. The taxonomic relationships with the other Sicilian taxa of the same section, in particular A. cupaniana, are also analyzed. The simultaneou…
The ‘recent’ forests of Mount Venda (Padua, Italy): when historical cartography and archaeobotany tell quite a different story
2018
Forests, like agricultural systems and housing, are an integral part of the human landscapes. They evolve over time, not only in response to environmental factors (e.g. climate change) but also in response to developments in human society. This work on the analysis of forest dynamics in Euganean hills is the result of research carried out as part of the research programmes THISTLE (MSCA Fellowship, grant agreement: 656397) and MEMOLA (EU FP7 Project , grant agreement: 613265). The work is focused on two mountains in particular: Monte Venda and Monte della Madonna. The archaeobotanical investigations reveal the presence of ancient forests (since the 14th century) in these areas , although th…
Taxonomic notes and critical discussion on the status of Hydnum notarisii (Basidiomycota) through the evaluation of Giuseppe Inzenga's original study…
2016
The current taxonomic status of Hydnum notarisii Inzenga is here critically analyzed on the basis of Giuseppe Inzenga’s original description and of the specimens kept in his private herbarium hosted in the Istituto Agrario Castelnuovo (Palermo, Italy) and in the Herbarium of Museum of Evolution, Uppsala University, Sweden (UPS). The detailed morphological study of the original dried material through the use of compound optical and scanning electron microscopy demonstrated that this particular fungus possesses very similar features with Hericium erinaceus (Bull.) Pers.
The Nonvolatile and Volatile Metabolites of Prangos ferulacea and Their Biological Properties
2019
Abstract Prangos ferulacea (L.) Lindl. (Fam. Apiaceae), an orophilous species of eastern Mediterranean and western Asia, possesses a number of biological properties that are worthy of exploitation in different fields. Phytochemical investigations revealed the presence of coumarins, prenyl-coumarins, and furano-coumarins as the main constituents of this species, as well as several flavonoids. Among prenyl-coumarins, osthol is a promising apoptotic agent quite selective toward cancer cells. In addition, the essential oils have been extensively investigated, and several chemotypes have been identified. This work reviews the literature on this species published between 1965 and 2018, describes …

Medicinal Mushrooms: Bioactive Compounds, Use, and Clinical Trials
2021
Medicinal mushrooms have important health benefits and exhibit a broad spectrum of pharmacological activities, including antiallergic, antibacterial, antifungal, anti-inflammatory, antioxidative, antiviral, cytotoxic, immunomodulating, antidepressive, antihyperlipidemic, antidiabetic, digestive, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and hypotensive activities. The growing interest in mycotherapy requires a strong commitment from the scientific community to expand clinical trials and to propose supplements of safe origin and genetic purity. Bioactive compounds of selected medicinal mushrooms and their effects and mechanisms in in vitro and in vivo clinical stu…
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…
Antologia di racconti postmaoisti (1977-1981)
2017
Il volume, corredato da una prefazione del Prof. Paolo Santangelo, comprende una lunga introduzione sullo sviluppo della letteratura cinese contemporanea incentrata sul racconto, e propone, nella traduzione italiana dell'Autrice stessa dall'originale in cinese, dodici racconti scritti fra il 1977 e il 1981. The volume includes a preface written by Prof. Paolo Santangelo, a long introduction to the contemporary Chinese literature based on the short story, and the translations by the Author herself into Italian from the original in Chinese of twelve short stories written between 1977 and 1981.
El análisis cuantitativo de trayectorias laborales. Un estado del arte
2022
La metodología cuantitativa aplicada al estudio de las trayectorias laborales ha experimentado un rápido auge que se ha extendido más allá del tradicional análisis de secuencias. El presente artículo es un estado del arte del desarrollo de nuevas técnicas estadísticas que pueden aplicarse o ya se aplican al estudio de trayectorias laborales. Además, incluimos sugerencias de software estadístico para la aplicación de cada una de las técnicas descritas. A lo largo de todo el texto, podrá observarse que la descripción de cada técnica se ha realizado desde un punto de vista conceptual, con el objetivo de llegar a un público amplio, que no necesite poseer una fuerte formación estadística. Es med…
Estudio del análisis de frecuencia de resonancia tras la colocación de 133 implantes dentales
2006
Introducción: La estabilidad primaria del implante dental está relacionada con el hueso que se encuentra en contacto con él y se puede medir mediante el análisis de frecuencia de resonancia. Material y métodos: En 133 implantes (62 en maxilar y 71 en mandíbula) se midió la frecuencia de resonancia y la fuerza de inserción para conocer la estabilidad de los implantes el día de la cirugía, y estudiar su relación con distintas variables. Resultados: El cociente de estabilidad del implante obtenido el día de la cirugía fue de 62'1 y el de la fuerza de inserción fue de 35'7 Nw. La fuerza de inserción fue proporcional al análisis de la frecuencia de resonancia, a mayor fuerza de inserción mayor c…
