Orgoglio poetico e lode del sovrano nei “carmina” di Enrico di Avranches per Federico II
2021
Nel 1878 Eduard Winkelmann pubblicò in «Forschungen zur deutschen Geschichte», tre carmina attribuibili a Enrico di Avranches, poeta normanno del XIII secolo. I tre componimeni sono trasmessi – come la stragrande maggioranza dei carmina di Enrico – dal ms. Dd. XI 78 della University Library di Cambridge, esemplato nel secolo XIII e appartenuto a Matteo Paris (siglum A). Questo intervento presenta una prima sezione dedicata alla presentazione della figura di Enrico di Avranches, con una rassegna bibliografica delle sue opere principali, alla quale segue una seconda e più ampia parte dedicata all’analisi dei tre carmina per Federico II, studiati nelle loro caratteristiche contenutistiche e fo…

Inhibition of the HER2 pathway by n-3 polyunsaturated fatty acids prevents breast cancer in fat-1 transgenic mice
2013
Overexpression of the tyrosine kinase receptor, ErbB2/HER2/Neu, occurs in 25–30% of invasive breast cancer (BC) with poor patient prognosis. Due to confounding factors, inconsistencies still remain regarding the protective effects of n-3 polyunsaturated fatty acids (PUFAs) on BC. We therefore evaluated whether fat-1 transgenic mice, endogenously synthesizing n-3 PUFAs from n-6 PUFAs, were protected against BC development, and we then aimed to study in vivo a mechanism potentially involved in such protection. E0771 BC cells were implanted into fat-1 and wild-type (WT) mice. After tumorigenesis examination, we analyzed the expression of proteins involved in the HER2 signaling pathway and lipi…
Isolation and characterization of 10 highly polymorphic di- and trinucleotide microsatellite markers in the mayfly Ameletus inopinatus (Ephemeroptera…
2008
We describe the isolation of ten polymorphic microsatellite loci from the mayfly Ameletus inopinatus. Loci had di- or trinucleotide repeat motifs and were highly variable with three to 17 alleles (mean = 7.15). Observed heterozygosity ranged from 0.143 to 0.905. One locus (Ami_202) showed significant deviation from Hardy–Weinberg equilibrium in one population, but no evidence for null alleles. One locus (Ami_73) was significantly linked with three other loci. The remaining nine loci should prove highly informative for population genetic studies.
Isolation and characterization of 11 polymorphic trinucleotide microsatellite markers in the stonefly Arcynopteryx compacta (Plecoptera: Perlodidae).
2011
We describe the isolation of 11 polymorphic trinucleotide microsatellite loci from the stonefly Arcynopteryx compacta. Loci were highly variable with 3 to 14 alleles (mean = 6.45). Observed heterozygosity ranged from 0 to 0.867. Seven loci showed significant deviation from Hardy–Weinberg equilibrium across both populations. There was no evidence for null alleles, and thus, Hardy–Weinberg departures could have resulted from genetic structure between populations or subpopulations. No linkage between loci was found. The 11 loci should prove highly informative for population genetic studies.
Heavy metals in coastal water systems. A case study from the northwestern Gulf of Thailand.
2005
A geochemical survey of the northwestern part of the Thailand Gulf (Inner Gulf) was carried out in order to define concentrations and distribution patterns of selected heavy metals (V, Cr, Co, Ni, Cu, Zn, and U) in the coastal system and estuarine area of the Mae Klong river. The results indicate the presence of two different sources of heavy metals in the studied environment and allowed us to identify a lithogenic component that significantly influences the composition of coastal waters and suspended particulate matter (SPM). Comparison of the normalized heavy metals concentrations both in the studied samples and in those reported for the Sn–W ores present in the surrounding areas suggests…
Sediment features, macrozoobenthic assemblages and trophic relationships (δ13C and δ15N analysis) following a dystrophic event with anoxia and sulphi…
2007
Macrozoobenthic assemblages and stable carbon (delta C-13) and nitrogen (delta N-15) isotope values of various primary producers (macroalgae and angiosperms) and consumers (macroinvertebrate filter/suspension feeders, deposit feeders, detritivores/omnivores and carnivores and fishes) were studied in the Santa Giusta lagoon (Sardinia, Italy) before (spring) and after (autumn) a dystrophic event which occurred in the summer of 2004. A few days after the dystrophy, the physico-chemical characteristics of sediments and macrozoobenthic assemblages were also investigated. In the latter occasion, high total organic carbon (3.9%) and organic matter (15.9%) contents of surface sediments went togethe…
Accumulation of trace metals in sediments in a Mediterranean Lagoon: Usefulness of metal sediment fractionation and elutriate toxicity assessment.
2015
International audience; The authors investigated sediment quality in Bizerte Lagoon (Tunisia) focusing on geochemical characteristics, metal sediment fractionation and elutriate toxicity assessment. Nickel, Cu, Zn, Pb, Cr and Cd partitioning in sediments was studied; accumulation and bioavailability were elucidated using enrichment factors, sequential extractions, redox potential, acid volatile sulfide and biotest procedures in toxicity evaluation. Results revealed an accumulation for Pb and Zn, reaching 99 and 460 mg kg−1 respectively. In addition, the acid volatile sulfide values were high in both eastern and western lagoon areas, thus affecting metal availability. Mean enrichment factor …
Un’antologia “sommersa”: "Il libro della memoria" di Gesualdo Bufalino
2018
The paper publishes and analyses as-yet-unpublished documents concerning an anthology on memory in literature, assembled by Gesualdo Bufalino and held in the archive of the Comiso Foundation. The unpublished anthology is accompanied by a letter to Elvira Sellerio, in which Bufalino explains its structure and choices, and by a series of eccentric texts that all revolve around the theme of memory. The drafts and the preparatory cartoons for the anthology in fieri alternate with textual fragments later included into the works of invention, lists of words, aphorisms, autonomous and complete texts (and among these a review as-yet-unpublished of the novel La palazzina di villeggiatura of Enrico J…
Gli «studia humanitatis» e i «fata iuris Romani» tra il fascio e la croce uncinata
2014
Il contributo contiene alcune riflessioni a proposito del volume di Bartocci "Salvatore Riccobono il diritto romano e il valore politico degli Studia Humanitatis" e si occupa del ruolo del diritto romano e dell'Istituto "Studia Humanitatis" nella particolare temperie del regime nazista in Germania e del regime fascista in Italia.
