Confinement stress in sea bass (Dicentrarchus labrax) depresses peritoneal leukocyte cytotoxicity
2002
Fish respond to stressful conditions via neuroendocrine responses (primary response) which result in increased levels of plasma cortisol which is considered immunosuppressive. Sea bass were confined at low (10 kg/m3) and high (60 kg/m3) density for 3-48 h. Plasma cortisol and glucose were evaluated and two principal cellular immune responses were assayed. A significant increase in plasma cortisol and glucose levels, as well as osmolarity, was found following stress. In addition, phagocytic activity, as shown by reactive oxygen species (ROS) production by challenged head kidney phagocytes and cytotoxic activity of eosinophilic granule cells from peritoneal cavity against K562 tumour cell lin…
MOMENTI E FIGURE DELLA CULTURA IN SICILIA FRA III E V SECOLO D.C.
2006
Si puntualizza che il filone oggi più promettente degli studi sulla Sicilia in età romano-imperiale e tardoantica è sempre più svincolato dai condizionamenti della ''pura'' storia politica, e apre ampie prospettive di ricerca, che si dispiegano – senza le rigide demarcazioni di un tempo – su molteplici aspetti, fra i quali quello socio-culturale e religioso. Su tale aspetto verte il contributo, ove si pone peculiare attenzione: alla figura di Porfirio e alla sua polemica con i suoi oppositori a Lilibeo, verosimilmente cristiani, di cui alla sua lettera alla moglie Marcella; alla figura di Firmico Materno e al suo ''De errore profanarum religionum'', ove è riflessa la specifica situazione re…
L’archéologue classique aux prises avec le monde diplomatique. Le cas de Salomon Reinach en 1881
2017
Classical Archeology Clashing with the World of Diplomacy: the Case of Salomon Reinach in 1881 Studies on the ties between archeology and diplomacy focus mostly on the way a few individuals reconciled a double career and realized the ideal of a hybrid figure: the diplomat as archeologist. Less attention has been paid to the relations, on a daily basis, between classical archeology and the world of consulates and embassies in the Eastern Mediterranean. Most of the time, one relies on the widespread cliché of the archeologist as a victim of bureaucracy. The case studied here is that of Salomon Reinach (1858-1932) and his abundant correspondence, held by the bibliothèque Méjanes (Aix-en-Proven…
I segni del Giudizio Finale nella tradizione letteraria basso tedesca
2014
THE SIGNS OF DOOMSDAY IN THE MIDDLE LOW GERMAN LITERARY TRADITION. During the Middle Ages the interest in eschatological themes pervades every expression of culture and spirituality in Germany. Theological speculation concentrated on issues linked to various events, such as the coming of the Antichrist, the Second Coming of Christ, the resurrection of the dead and the Last Judgment. This particular cultural framework represents the background of the circulation and success of the legend of the fifteen signs before Doomsday, concerning wonders and fatal events occurring in the two weeks before the end of the world. This legend enjoyed large circulation throughout the Middle Ages, and found e…
Modulation of cytochrome P450 1A in sea bass liver by model substances and seawater extracts
1998
Abstract 1. 1. Immunochemical and catalytic assays for cytochrome P450 1A induction in liver of sea bass Dicentrarchus labrax treated with different model substances and organic seawater extracts have been performed. 2. 2. Ethoxyresorufin-O-deethylase (EROD) activities in fish liver were elevated by Arochlor 1254 (Aro), 3-methylcholanthrene (MC) and β-naphtoflavone (βNF). but not by phenobarbital (PB) treatment. 3. 3. Elevated levels of P450 1A protein followed by induction of EROD activity were detected only in βNF treated fish. 4. 4. Treatment of fish with organic seawater extracts revealed that there is no simple correlation between EROD activities and its catalyst P450 1A level. Seawate…
Isolation and characterization of a fish F-type lectin from gilt head bream (Sparus aurata) serum.
2007
A novel fucose-binding lectin, designated SauFBP32, was purified by affinity chromatography on fucose-agarose, from the serum of the gilt head bream Sparus aurata. Electrophoretic mobility of the subunit revealed apparent molecular weights of 35 and 30 kDa under reducing and non-reducing conditions, respectively. Size exclusion analysis suggests that the native lectin is a monomer under the selected experimental conditions. Agglutinating activity towards rabbit erythrocytes was not significantly modified by addition of calcium or EDTA; activity was optimal at 37 degrees C, retained partial activity by treatment at 70 degrees C, and was fully inactivated at 90 degrees C. On western blot anal…
A serum fucolectin isolated and characterized from sea bass Dicentrarchus labrax
2001
A lectin specific for fucose and galactose was isolated by affinity chromatography on Sepharose CL-6B from the serum of Dicentrarchus labrax. The hemagglutinating activity against rabbit erythrocytes was calcium-independent, and reached its maximum at 37 degrees C. Two protein components were found in the hemagglutinating fractions eluted from the Sepharose column. Only the 34 kDa component (DLL2) eluted from the polyacrylamide gels (SDS-PAGE) showed agglutinating activity against rabbit erythrocytes. SDS-PAGE, in non-reducing conditions, revealed a single 66 kDa protein that reacted with antibodies to the 34 kDa component. Therefore, a dimeric structure stabilized by disulfide bonds can be…
Commensality in the Late Bronze Age : places and practices : the contribution of recent discoveries in the south-east of the Paris Basin
2021
This doctoral dissertation uses data from the extensive preventive archaeological research carried out in the Upper Seine Valley in the south-east of the Paris Basin for at least five decades an area where Bronze Age and Early Iron Age sites are numerous and generally well preserved. The 2005 excavation by Inrap of the Villiers-sur-Seine site "le Gros Buisson", an "unusual" settlement dating to the final phase of the Late Bronze Age (9th century B.C.) is the main focus of this study, having shed new light on domestic contexts of this pivotal period. This fortified aristocratic dwelling is characterised by an organised plan, abundant artefacts, as well as the unusual consumption of young pig…
Tomato leaf miner Tuta absoluta (Meyrick,1917) (Lepidoptera: Gelechiidae) The old and new challenge
2014
The term Phytosanitary exists within many of the modern and old scientific terms such as: organic farming, plant protection, integrated pest management, national and international movement of plant germplasm, biosecurity, good agricultural practices and others. There are many aspects within those related terms. All those terms have common interests of which the pests' risk be avoided and the environmental health is achieved. Consequently preventive measures, precaution measures and effective testing procedures are required. The study problem is the pest Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), the Tomato leaf miner, this pest is one of the most devastating pests affecting T…
Confronto tra la nematofauna delle monoculture di mais e quella dei sistemi erbacei
2023
Gli studi sugli effetti dell'agricoltura sulla biodiversità del suolo sono diventati molto importanti, al fine di proteggere la salute dell'ambiente e migliorare la qualità dell'agricoltura. Le comunità di nematodi hanno dimostrato di offrire un potente strumento ecologico per valutare gli effetti delle pratiche agricole sul suolo. La ricerca è stata condotta in una monocoltura di mais (della durata di 20 anni) e in un ecosistema erbaceo seminaturale, dominato da Festuca spp. e Trifolium spp.. Ciascun sistema è stato sottoposto a due diverse pratiche di gestione delle colture (input alto (H) e basso (L)). L'obiettivo era quindi quello di studiare gli effetti di due diversi ecosistemi e dive…
