Chemical Composition of the Essential Oil of Bupleurum Fontanesii (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Hist…
2016
Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.
Pour une anthropologie pragmatiste et plébéienne du patrimoine : un scenario contre-hégémonique
2019
À partir de plusieurs constats, le débordement des institutions patrimoniales, l’insistance de formes citoyennes ou plébéiennes des revendications d’attachements, la prégnance de la figure du vivant, la raréfaction du futur devant la perspective anthropocénique, ce texte voudrait jeter les bases d’un scénario contre-hégémonique du patrimoine : détaché des institutions d’État, loin du marché et de sa logique néo-libérale, engagé dans des expériences de problèmes publics, sensible à la pluralité ontologies et des modes de connaissance… Some preliminary observations: too much is now asked of heritage institutions; new citizens’ and plebeian forms are emerging of asserting attachments; life-sci…

Rubefacientu (mentola un niacīna) izraisīto mikrocirkulācijas reakciju novērtējums ādas dažādos dziļumos
2017
Ādai ir lokāla neiro-imuno-endokrīnā sistēma, kas lielā mērā atspoguļo organisma norises, kalpojot par sava veida „veselības indikatoru”. Īpaši pievilcīga un relatīvi pieejama ir ādas mikrocirkulācijas funkciju novērtēšana, ko var neinvazīvi veikt ar optiskām metodēm. Parasti praksē šādu reakciju novērtēšanai tiek lietoti standartizēti provokācijas testi, kā, piemēram, lokālas sildīšanas tests, vai acetilholīna jontoforēze. Taču bieži vien ādas sarežģītā mikrocirkulācija un liela regulācijas mehānismu daudzveidība apgrūtina rezultātu viennozīmīgu interpretāciju. Šajā kontekstā daudzsološa šķiet bispektrālā attēlveides fotopletizmogrāfija - optiska metode ar kuras palīdzību, izmantojot atšķi…

α-Conotoxins EpI and AuIB switch subtype selectivity and activity in native versus recombinant nicotinic acetylcholine receptors
2003
The Xenopus laevis oocyte expression system was used to determine the activities of alpha-conotoxins EpI and the ribbon isomer of AuIB, on defined nicotinic acetylcholine receptors (nAChRs). In contrast to previous findings on intracardiac ganglion neurones, alpha-EpI showed no significant activity on oocyte-expressed alpha3beta4 and alpha3beta2 nAChRs but blocked the alpha7 nAChR with an IC50 value of 30 nM. A similar IC50 value (103 nM) was obtained on the alpha7/5HT3 chimeric receptor stably expressed in mammalian cells. Ribbon AuIB maintained its selectivity on oocyte-expressed alpha3beta4 receptors but unlike in native cells, where it was 10-fold more potent than native alpha-AuIB, had…
Ground and first excited electronic state interaction of FAD with some β-carboline derivatives
1987
Abstract The spectrophotometric and thermodynamic properties of molecular complexes of flavine adenine dinucleotide (FAD) with some dihydro β-carboline derivatives have been investigated in aqueous solution. The molecular associations have been examined by means of electronic absorption spectra, since in each a new charge-transfer band has been located, and also the variation of the fluorescence emission of FAD on the solutions has been observed. The formation constants for the molecular complexes were determined from absorption data, using the Foster-Hammick-Wardley method. The quenching fluorescence phenomena observed in FAD is related to the concentration of the dihydro β-carboline deriv…

Some characterisations of groups in which normality is a transitive relation by means of subgroup embedding properties
2018
[EN] In this survey we highlight the relations between some subgroup embedding properties that characterise groups in which normality is a transitive relation in certain universes of groups with some finiteness properties.
