Studi greci e latini nell?antica Università di Altamura (1748-1821)
2019
The article tries to highlight, despite the scarse of available documentation, the Greek and Latin studies (language and texts) in the ancient Apulian University in Altamura (1748-1821). Furthermore, on the basis of unpublished archival materials (school registers and student workbooks) it is possible to shed light on the ancient authors explained at school, the teaching methods, and the study practices.
Inuentiones y translationes de S. Mercurio
2019
Inuentiones and translationes of the relics are part of the hagiographic dossier of a saint and provide interesting information about his cult over the centuries. For S. Mercurius of Caesarea the original texts in Greek have been lost, but we have two collections miracles in Coptic that narrate the inuentio and translatio of his relics and there is also a medieval tradition about his translatio to Benevento (Italy). From all these texts is deduced a healing cult of S. Mercurius based on the usual topics.

Pyrano[2,3-e]isoindol-2-ones, new angelicin heteroanalogues
2009
A convenient synthesis of the pyrano[2,3-e]isoindol-2-one ring system, an heteroanalogue of angelicin, is reported. Our synthetic approach consists of the annelation of the pyran ring on the isoindole moiety using 5-dialkylamino- or 5-hydroxymethylene intermediates as building blocks. The photoantiproliferative activity of the new derivatives was studied. Some of them bearing the benzyl group at the 8 position were active with IC(50) in the micromolar range. Cell cytotoxicity involves apoptosis, alteration of cell cycle profile and membrane photodamage.
In vitro Antifungal Activity of Biopolymeric Foam Activated with Carvacrol
2020
Background: Active packaging represents a defining strategy to improve food quality and safety of the packaged foods. This study aimed to evaluate the in vitro ability of commercial biopolymeric foams, namely Mater-Bi (MB), activated with 20% of carvacrol, to develop a completely biodegradable and compostable packaging to inhibit the growth of spoilage and pathogenic yeasts.
 Methods: MB foams, with and without carvacrol, were produced by melt mixing and the foaming process was performed in a laboratory press. The antifungal activity of foams containing carvacrol was tested applying the disk diffusion method. Statistical analysis was done using XLStat software version 7.5.2 for Excel.&…
Antiproliferative and chemomodulatory effects of interferon-γ on doxorubicin-sensitive and -resistant tumor cell lines
1993
Biological agents might offer various therapeutic opportunities in the treatment of cancer, including a direct and/or host-mediated antiproliferative effect and also the possibility to favorably modulate tumor resistance to antineoplastic drugs. We studied the in vitro antiproliferative effects of interferon (IFN)-gamma on the mouse B16 melanoma and Friend erythroleukemia, and the human K562 erythroleukemia, as doxorubicin (DXR)-sensitive and -resistant (multidrug resistant) variants. These effects were marked in B16 melanoma and rather slight in K562 erythroleukemia, without any difference between the DXR-sensitive and -resistant lines. The chemosensitive variant of Friend erythroleukemia …
Identification of Biphenyl-Based Hybrid Molecules Able To Decrease the Intracellular Level of Bcl-2 Protein in Bcl-2 Overexpressing Leukemia Cells
2009
With the aim of enhancing the structural complexity and diversity of an existing collection of bi- and terphenyl compounds, we synthesized hybrid molecules comprising of spirocyclic ketones (a complexity-bearing core) and bi/terphenyls (privileged fragments). Compounds 1, 3, 4, and 6 showed well-defined activity on apoptosis and differentiation, making them potential leads for development as new anticancer agents and chemical probes to study signaling networks in neoplastic cells.
Antimicrobial and antiproliferative activity of Peucedanum nebrodense (Guss.) Strohl.
2003
Abstract Acetone extract of Peucedanum nebrodense (Guss.) Strohl., a rare endemic species from the Madonie mountains (Sicily), was tested in vitro for its antimicrobial activity against bacterial reference strains and antiproliferative activity against K562 (human chronic myelogenous leukemia), HL-60 (human leukemia) and L1210 (murine leukemia) cell lines. The acetone extract showed antiproliferative IC 50 values in the range of 14–0.27 μg/ml.
