Molecular cloning and functional bacterial expression of a plant glucosidase specifically involved in alkaloid biosynthesis.
2000
Monoterpenoid indole alkaloids are a vast and structurally complex group of plant secondary compounds. In contrast to other groups of plant products which produce many glycosides, indole alkaloids rarely occur as glucosides. Plants of Rauvolfia serpentina accumulate ajmaline as a major alkaloid, whereas cell suspension cultures of Rauvolfia mainly accumulate the glucoalkaloid raucaffricine at levels of 1.6 g/l. Cell cultures do contain a specific glucosidase. known as raucaffricine-O-beta-D-glucosidase (RG), which catalyzes the in vitro formation of vomilenine, a direct intermediate in ajmaline biosynthesis. Here, we describe the molecular cloning and functional expression of this enzyme in…
New reaction of 1H-pyrazoles with selenium dioxide: one-pot synthesis of bis(1H-pyrazol-4-yl)selenides
2010
Abstract A novel reaction between 3- and 3,5-substituted pyrazoles with selenium dioxide proceeds with formation of bis(3R,5R′-1H-pyrazol-4-yl)selenides in high yield. On this basis, an efficient one-pot synthetic procedure has been developed. In the case of the unsubstituted pyrazole a selenonium compound has been obtained. The identity and structure of the isolated selenium derivatives have been confirmed by spectral methods and their molecular structures investigated by X-ray analysis.
“If you seek it, you will find it”. Methodology for the carpological study of the Middle Magdalenian of Cova de les Cendres site (Teulada-Moraira, Al…
2016
La carpología, el estudio de los frutos, semillas, tubérculos, rizomas y bulbos recuperados en yacimientos arqueológicos, ha sido aplicada mayoritariamente a contextos correspondientes a sociedades productoras, mientras que los estudios carpológicos de yacimientos de cazadores-recolectores son escasos. En los últimos años, estos han experimentado un incremento, desvelándose el valor de la información que proporcionan: económica, cultural, botánica y ecológica. Presentamos en este artículo la metodología aplicada para el análisis carpológico de un conjunto de muestras procedentes de un nivel fechado en el Magdaleniense medio de la Cova de les Cendres (Teulada-Moraira, Alicante).
Detrital zircon and micropalaeontological ages as new constraints for the lowermost tectonic unit (Talea Ori unit) of Crete, Greece
2007
The Talea Ori unit is the lowermost known tectonic unit of Crete and the most external part of the Hellenides. Its stratigraphy ranges from Late Carboniferous to Oligocene and outcrops of the lower part are only known in the Talea Ori mountains (central Crete). In this area, a black sandstone at the base of the Galinos Beds, thought to be the oldest formation, contains zircons which were dated using the single grain evaporation method. The majority of these grains yielded Late Carboniferous ages (Variscan), while a small group yielded Early Proterozoic ages. The age distribution of these zircons suggests that, at the Carboniferous–Permian boundary, not much of the older North Gondwanan base…
Le sculture da Alesa

First publication of a group of ideal and iconic sculptures from the central area of Alesa, within the excavation edition of the agora, and of a Hellenistic sculpture from the main sanctuary
Philosophical thought of the School of the Sextii
2014
Around the first half century B.C. the first Roman school of philosophy arose, which was called School of Sextii. The known members of the School were: Quintus Sextius the Elder, founding father of the School, Sextius Niger, Quintus' son, who became scholarch of the School after his father's death, Sotion, Papirius Fabianus (both teachers of Seneca the Younger), Crassicius Pasicles, a grammarian, and Celsius Cornelius, an expert doctor. The School followed the footsteps of the Hellenistic schools, and similar to these, the pursuit of happiness was its purpose. The school of the Sextii had taken to heart that part of the philosophy called physical, characterizing itself mainly as a philosoph…
Production technology of early-hellenistic lime-based mortars originating from a punic-Roman residential area in palermo (sicily)
2016
The topic of this study is the mineralogical and petrographic characterization of lime-based mortars of Hellenistic-Roman age (3rd century BCE), collected from a residential area located in the present historical centre of Palermo, near the remains of the Punic-Roman walls. The collected mortars have been analyzed by optical microscopy, X-ray powder diffraction analysis and scanning electron microscopy, coupled with energy-dispersive spectrometry. The aim of the study was the characterization of the mortars as pertaining to their aggregate and binder composition, aggregate size distribution and aggregate/binder ratio, so as to establish the provenance of raw materials and acquire informatio…
Heliodorus Parthenopaeus: The "Aithiopika" in Baroque Naples
1998
L'articolo è frutto di un lavoro comune; i paragrafi 1, 3 e 6 sono stati redatti da Massimo Fusillo, i paragrafi 2, 4 e 5 da Clotilde Bertoni. Il lavoro analizza il "Teagene", poema epico di Giambattista Basile ispirato alle "Etiopiche" di Eliodoro, e prende in esame altre opere seicentesche legate al romanzo ellenistico. The article results from a common work: paragraphs 1, 3 and 6 have been written by Massimo Fusillo, paragraphs 2, 4 and 5 by Clotilde Bertoni. It analyzes "Teagene" an epic poem by Giambattista Basile, based on Heliodorus' Aethiopica, and it also examines some other works of the same period connected with th Hellenistic novel.
