No full textIn Italy, there is a long-held tradition concerning the cultivation of Prunus avium L. (Rosaceae) fruits used both for eating and for making juices, jams, and drinks (1). P. avium, commonly called “sweet cherry”, is a vigorous tree extensively distributed in temperate areas of the world (2). Its fruits, which ripen between May and July, are very popular not only for their taste, colour, and sweetness but also for their nutritional properties consisting in a considerable amount of phenolic compounds (3). Despite the wide-spread interest in cherries, little is known about the chemical composition and bioactive properties of P. avium petioles which are considered plant waste without any commercial interest (2,4). The aim of this work was to compare six ancient Italian cultivars both for the phenolic and anthocyanin content of fruits (pulp and peel) and chemical constituents of petioles by HPLC-PDA-ESI-MS/MS analyses. Furthermore, the antitumor activity of phenolic compounds with a particular focus on apoptosis-inducing and potential cytotoxic effects was investigated. As far as we know, no research on the potential anti-angiogenic activity of P.avium has been yet reported. Therefore, the biological effect of fruit and petiole extracts of each cultivar on the formation of new blood vessels using as an in vivo model the chick embryo chorioallantoic membrane (CAM) was explored.
Among Italian cherries, the following cultivars were selected: Ferrovia (from the Puglia Region), Capellina, Morellina, Ciambellana, Napoletana, and Bianca (from the Casentino area in Tuscany, see http:/germoplasma.regione.toscana.it/) (5).
The quali-quantitative analysis of fruit extracts evidenced a similar phenolic profile with coumaroyl quinic acids, chlorogenic acid, rutin, kaempferol 3-O-rutinoside, and kaempferol 3-O--D-glucopyranoside, as the most representative compounds for all cultivars. Moreover, cyanidin-3-O-rutinoside was the only anthocyanin detected in all the cultivars (except for Bianca where anthocyanins were completely absent), being the most abundant in Capellina and Morellina cultivars. All cultivars petiole extracts resulted in a similar phenolic profile, among which the major constituents were catechin, taxifolin 7-O--D-glucopyranoside, apigenin 4-O--D-glucopyranoside, apigenin 5-O--D-glucopyranoside, naringenin 7-O--D-glucopyranoside, pinocembrin 7-O--D-glucopyranoside, chrysin 7-O--D-glucopyranoside, dihydrowogonin 7-O--D-glucopyranoside, and rutin, being Capellina, Napoletana and Bianca characterized also by the presence of procyanidin B type dimers and trimers.
Biological results showed that among fruit extracts, Ferrovia, Morellina, and Capellina cultivars exhibited the best antiangiogenic response inducing a marked reduction of the microvasculature of the CAMs (30.7-43.5% of inhibition at 100 and 160 μg/egg). In addition, the biological screening showed a good inhibition on the capillary growth even after treatment of the CAMs with Morellina, Ferrovia, and Ciambellana petiole extracts (30.6- 42.4% of inhibition at 100 and 160 μg/egg).
In conclusion, the extracts from P. avium cultivars here presented can be considered a valuable source of angiomodulators

No full textTetragus impunctatus (Dupuis, 2019)comb. nov. Gibboryctes impunctatus Dupuis 2019: 180 (description), 181 (holotype illustration) Diagnosis Tetragus impunctatus differs from P. waldenfelsi by the smooth pronotal concavity in male and female with tergite VIII weakly convex in lateral view (Dupuis 2019; Ratcliffe et al. 2020). Geographical distribution (Figure 14 (a)) Known from Peru and Ecuador (Dupuis 2019; Ratcliffe et al. 2020). Remarks This species was described by Dupuis (2019) and subsequently redescribed by Ratcliffe et al. (2020) concomitantly to our revision of Gibboryctes. For this reason, the species description was not included in this revision.Published as part of Costa, Leidiane O., Duarte, Paulo R.

Environmental influence on the IR fluorescence of Xe-2* molecules in electron beam excited Ar-Xe mixture at high density
No full textWe report new measurements of the near infrared (NIR) Xe2* excimer fluorescence in an electron beam excited Ar (90%) Xe (10 %) mixture at room temperature. Previous measurements up to a density N≈ 2× 1026 m-3 discovered a broad excimer fluorescence band at ≈ 7800 cm-1, whose center is red shifted by increasing N [A.F. Borghesani, G. Bressi, G. Carugno, E. Conti, D. Iannuzzi, J. Chem. Phys. 115, 6042 (2001)]. The shift has been explained by assuming that the energy of the optical active electron in the molecule is shifted by the density dependent Fermi shift and by accounting for the solvation effect due to the environment. We have extended the density range up to N≈ 6× 1026 m-3, confirming the previous measurements and extending the validity of the interpretative model. A detailed analysis of the width of the fluorescence band gives a value of 2.85 nm for the size of the investigated excimer state. Such a large value lends credibility to the validity of the proposed explanation of the experimental findings
Werner Sombart and the global society. Anticipations from a classic author of sociology
No full textThe article examines the most salient works in which the sociologist Werner Sombart saw the dimension of globality as a social element, constitutive of mo- dernity and its future. The aim is to understand the role of globality, as an idea and a phenomenon, in the constitution in all aspects of society (economic, political, cultural, anthropological). The Works to which the article refers show a global society, one that goes from the time of Sombart to the present day, as the author had already envisioned in all their potentialities and criticalities
