GDNF reverses priming for dyskinesia in MPTP-treated, L-DOPA-primed common marmosets
2001
Parkinson's disease (PD) is associated with a progressive loss of dopamine neurons in the substantia nigra and degeneration of dopaminergic terminals in the striatum. Although L-DOPA treatment provides the most effective symptomatic relief for PD it does not prevent the progression of the disease, and its long-term use is associated with the onset of dyskinesia. In rodent and primate studies, glial cell line-derived neurotrophic factor (GDNF) may prevent 6-OHDA- or MPTP-induced nigral degeneration and so may be beneficial in the treatment of PD. In this study, we investigate the effects of GDNF on the expression of dyskinesia in L-DOPA-primed MPTP-treated common marmosets, exhibiting dyskin…
Intrinsic competition between two European egg parasitoids of the brown marmorated stink bug
2020
Following the accidental introduction and spread of the invasive polyphagous agricultural pest Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), the two European egg parasitoids Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) have been investigated for inundative biological control. Since the competititve outcome between the two generalist parasitoids is difficult to predict, intrinsic competition was investigated with a time-course development study. Both species readily oviposited in H. halys eggs containing eggs and early instar larvae of the competitor, but oviposition decreased when eggs contained late insta…
“Things which don’t shift and grow are dead things”: Revisiting Betonie’s Waste-Lands in Leslie Silko’s Ceremony
2014
This article explores the socio-political background that led to widespread Native American urban relocation in the period following World War II – a historical episode which is featured in Leslie Marmon Silko’s acclaimed novel Ceremony (1977). Through an analysis of the recycling, reinterpreting practices carried out by one of Ceremony’s memorable supporting characters, Navajo healer Betonie, Silko’s political aim to interrogate the state of things and to re-value Native traditions in a context of ongoing relations of coloniality is made most clear. In Silko’s novel, Betonie acts as an organic intellectual who is able to identify and challenge the 1950s neocolonial structure that forced Na…
La fortuna del capitello ionico nella Gortina imperiale: i modelli microasiatici e le rielaborazioni in marmo grigio locale
2020
Le indagini archeologiche nella città di Gortina hanno riportato in luce alcuni capitelli ionici di modello microasiatico in marmo importato, databili alla seconda metà del II sec. d.C., ma anche un gran numero di capitelli ionici in marmo grigio locale, con ogni evidenza prodotti in loco tra la fine del II e gli inizi del III sec. d.C. Si tratta di membrature riutilizzate in edifici più tardi e spesso reimpiegate come materiale da costruzione o rifunzionalizzate in vari modi. La loro relativa abbondanza, per alcuni versi insolita, testimonia non solo la peculiare fortuna del tipo nella capitale cretese, ma anche la grande attività degli atelier di scalpellini locali, almeno a partire dalla…
Multidisciplinary Approaches to Study Ancient Cities in a Seismic Region
2022
The paper focuses on the strong connections between natural resources, environment, and urban development in the Hellenistic, Roman, and Byzantine city of Hierapolis of Phrygia (Pamukkale, Turkey). The ancient city was founded on a travertine terrace crossed by an active fault, responsible for impressive geothermal phenomena, i.e., flowing of thermal water, emission of gases, and frequent earthquakes, while the surrounding territory offered various stone qualities (travertine, alabaster, marbles, etc.). These environmental features affected the cultural identity of Hierapolis and its urban layout, conditioning also the construction techniques and the monumentalization of the city. In recent…
La Madonna di Trapani di Nino Pisano e i suoi epigoni
2020
La scultura della Madonna di Trapani del Santuario dell’Annunziata, riferita a Nino Pisano, che introduce l’iconografia della Vergine in amorevole colloquio, favorì la produzione di numerose copie del simulacro marmoreo sin dal XV secolo. Tra le tarde riproposizioni viene inserita la statua alabastrina della Madonna con il Bambino del Museo Diocesano di Palermo. The sculpture of the Madonna of Trapani of the Santuario dell'Annunziata, referring to Nino Pisano, who introduces the iconography of the Virgin in loving conversation, favoured the production of numerous copies of the marble simulacrum since the 15th century. The alabastrine statue of the Madonna and Child of the Diocesan Museum of…
Metabolic activation of aflatoxin B1 to aflatoxin B1-8,9-epoxide in woodchucks undergoing chronic active hepatitis
1997
Chronic hepatitis B virus infection as well as consumption of food contaminated with the mycotoxin aflatoxin B1 are considered to be 2 major risk factors for the development of primary liver cancer in humans. Furthermore, epidemiological surveys indicate that hepatitis B virus and aflatoxin B1 might act synergistically to induce primary liver cancer. In the present study, we have tested the hypothesis that the metabolic activation of aflatoxin B1 to aflatoxin B1-8,9-epoxide, the ultimate mutagenic and carcinogenic mycotoxin metabolite, is enhanced in an experimental model of chronic hepatitis using woodchucks, chronically infected with the woodchuck hepatitis virus. Woodchuck liver microsom…
Multifocal aplasia cutis congenita, distal limb hemimelia, and cutis marmorata telangiectatica in a patient with Adams-Oliver syndrome.
1992
Summary We describe an 18-month-old boy with multifocal scalp defects over the posterior parietal region combined with an underlying defect of the skull, left lower limb distal hemimelia and generalized cutis marmorata telangiectatica, consistent with a diagnosis of Adams–Oliver syndrome (aplasia cutis congenita with distal transverse limb defects).
L’altare di Maria Santissima del Lume nella chiesa delle Anime Sante a Valletta.
2015
Il contributo si occupa di ricostruire, attraversi documenti finora mai pubblicati, le vicende realizzative relative all'inedito altare maggiore della chiesa delle Anime Sante a Valletta (Malta), opera dei maestri marmorari messinesi Antonino e Francesco Amato e aiuti degli anni 1743-1747. The essay, through documents never before published, speaks of the events related to the construction of the main altar of the church of the Holy Souls in Valletta (Malta). It is a work of the marble workers Antonino and Francesco Amato and aid from Messina made in the years 1743-1747.
Genetic architecture of the marbled goby Pomatoschistus marmoratus (Perciformes, Gobiidae) in the Mediterranean Sea
2011
The marbled goby Pomatoschistus marmoratus, a species inhabiting coastal Mediterranean lagoons, has been studied by measuring its mitochondrial DNA variation. This analysis revealed a Mediterranean west vs east split and, subsequently, an eastern differentiation among the Libyan–Tunisian Gulf, the Adriatic Sea and the Aegean Sea. The high cohesion between the samples collected in the vast area of western Mediterranean contrasts with the genetic mosaic of the more sub-structured eastern Mediterranean. This western homogeneity can not yet be fully explained even if a human-mediated migratory flow, due to a maritime traffic, has been posited. The pattern in the eastern basin revealed a genetic…
