"L'urbanistica si identifica con la sua storia": Edoardo Caracciolo e la disciplina storico-urbanistica

2014

«L’urbanistica si identifica con la sua storia»: con una affermazione così forte Edoardo Caracciolo nel lontano 1950 intitolava un articolo destinato alla rivista «Le Opere». Il saggio indaga il complesso rapporto tra urbanistica e storia nel pensiero e nell'opera di uno dei padri non solo dell'urbanistica, ma anche della storia della città in Italia.

Hallazgo de un denario merovingio inédito de Marsella en la ciudad de Tarragona (España)

2019

Documentamos el importante descubrimiento de un denario merovingio procedente de Masilia (Marsella) en la ciudad catalana de Tarragona (España). Debido a la escasez de esta tipología, no solamente en el suelo peninsular, creemos que su publicación es de una gran importancia. Y más aún considerando que el estudio de las relaciones comerciales tanto de corto como de largo recorrido entre el reino visigodo de Toledo y la Francia merovingia se mantiene poco desarrollado. We study the important fi nding of a Merovingian denarius from Masilia (Marseille) in the Catalan city of Tarragona (Spain). Due to the scarcity of this coinage, not only in the Iberian Peninsula, we believe that its publicatio…

New Gold(I) Organometallic Compounds with Biological Activity in Cancer Cells

2014

N-Heterocyclic carbene gold(I) complexes bearing a fluorescent coumarin ligand were synthesized and characterized by various techniques. The compounds were examined for their antiproliferative effects in normal and tumor cells in vitro; they demonstrated moderate activity and a certain degree of selectivity. The compounds were also shown to efficiently inhibit the selenoenzyme thioredoxin reductase (TrxR), whereas they were poorly effective towards the glutathione reductase (GR) and glutathione peroxidase enzymes. Notably, {3-[(7-methoxy-2-oxo-2H-chromen-4-yl) methyl]-1-methylimidazol-2-ylidene}(tetra-O-acetyl-1-thio-beta-D-glucopyranosido) gold(I) (3) showed a pronounced inhibition of TrxR…

Focs que no cremen en l'hagiografia tardoantiga i bizantina

2018

L'ús del foc com a element per a martiritzar santes i sants cristians va ser molt estés, tal com ho testimonia la literatura hagiogràfica de l'antiguitat tardana i d'època bizantina. Els autors relaten casos miraculosos en què els màrtirs no es veuen afectats per les flames gràcies a la intervenció divina. Es tracta d'un motiu literari i folklòric que arranca de l'Antic Testament (llibre de Daniel), apareix a la novel·la grega antiga i passa al'hagiografia, influenciada pel gènere novel·lístic. L'efecte d'aquest prodigi pretén que el missatge religiós assolisca més força en els fidels i que augmente el poder de la fe cristiana.

UV-induced cross-linking of proteins to plasmid pBR322 containing 8-azidoadenine 2′-deoxyribonucleotides

1988

Abstract An efficient method of cross-linking DNA to protein is described. The method is based on the incorporation of photoactive 8-azidoadenine 2′-deoxyribonucleotides into DNA. We have found that 8-N 3 dATP is a substrate for E. coli DNA polymerase I and that 8-N 3 dATP can be incorporated into plasmid pBR322 by nick-translation. Subsequently we were able to cross-link a set of different proteins to 8-azido-2′-deoxyadenosine-containing pBR322 by UV irradiation (366 nm). No DNA-protein photocross-linking was observed under the same conditions when the non-photoactive plasmid pBR322 was used.

Lo sparo e l’orologio. "Appunti" nel sistema del "Piccolo Berto" (e oltre)

2021

The essay analyzes Umberto Saba's poem Appunti in the belief that this text presents new themes and new formal strategies that are used in Il piccolo Berto and are destined to persist beyond that. In its broken and discontinuous brevity, Appunti says without explaining, it expresses a trauma that Saba does not verbalize. Saba burns the causal passages and requires the cooperation of the reader, forcing him to contribute to the construction of meaning and to fill the gaps in a text, in which silences and typographical leaps are worth as much as words. The analysis focuses on the modernity of a formal choice in which syntactic divisions and white spaces dramatize the inner restlessness. At th…

Occurrence and virulence of Pseudoalteromonas spp. in cultured gilthead sea bream (Sparus aurata L.) and European sea bass (Dicentrarchus labrax L.).…

2007

During two long-term bacteriological surveys in European sea bass (Dicentrarchus labrax L.) and gilthead sea bream (Sparus aurata L.) culture facilities on the Spanish Mediterranean coast, four different species of Pseudoalteromonas were found in the internal organs of animals. Pseudoalteromonas undina, Pseudoalteromonas haloplanktis, P. espejiana and Pseudoalteromonas sp. were isolated from 9% out of 177 European sea bass and 11.7% out of 547 gilthead sea bream and they were recovered as pure cultures in 50% of isolations. Among fish with positive bacterial growth, Pseudoalteromonas was more prevalent in sea bass showing clinical signs (27.7%) and in gilthead sea bream without clinical sig…

What’s the resolutive surgery for Pseudo-Ainhum in vohwinkel syndrome? A case report and review of the literature

2021

Vohwinkel Syndrome, also known as Keratoderma Hereditarium Mutilans, is an extremely rare dominant autosomal keratosis. It typically presents with “starfish” keratoses on the knuckles, palmoplantar keratoderma (PPK), hearing impairment and mutilating digital constriction bands (pseudoainhum) that cause strangulation, often leading to autoamputation of the affected digit. Both medical and surgical treatment haven’t shown to date consistent results, in the treatment of pseudoainhum. In this study we present the case of a woman with Vohwinkel syndrome who showed constriction bands causing ischemic changes of the 5th digit of the right hand for which she was treated with surgery. We also presen…

Carriage of potentially fish-pathogenic bacteria in Sparus aurata cultured in Mediterranean fish farms.

2003

A bacteriological survey of gilthead sea bream Sparus aurata from different fish farms and culture systems on the Spanish Mediterranean coast was conducted. Three different studies were performed. Study A included hatchery-reared larvae; Study B, periodic examination of randomly sampled growing fish; and Study C, growing fish sampled only during mortality/morbidity events. In Studies B and C, sea cages, earth ponds and indoor tanks were surveyed, and in both cases diseased (showing clinical signs) and non-diseased fish were included. In Study A, a shift from Vibrio spp. (30 d after hatching) to oxidative species (60 d after hatching) was detected, and no mortality events were registered. Th…
