Polybrominated methoxy diphenyl ethers (MeO-PBDEs) in fish and guillemot of Baltic, Atlantic and Arctic environments
2003
Arctic cod liver samples from Vestertana Fjord at the Arctic coast of Norway, salmon and guillemot samples from the Baltic Sea and the Atlantic Ocean, and salmon and lamprey larva samples from Kymijoki River in southern Finland were analysed for the occurrence of tri-, tetra- and pentabromomethoxy diphenyl ethers and their concentration levels were estimated. These compounds have previously been identified by other research groups in salmon, seal and dolphin samples. The aim of this study was to find out a possible temporal trend in the concentrations of these compounds in the cod liver samples from years 1987-1998 and to investigate the possible spatial differences in the concentrations in…
Contaminants of emerging concern in freshwater fish from four Spanish Rivers.
2019
This study investigated the occurrence of 135 contaminants of emerging concern (CECs) – pharmaceuticals, pesticides, a set of endocrine disrupting compounds (EDCs) (parabens, bisphenols, hormones, triazoles, organophosphorus flame retardants and triclosan), UV-filters, perfluoroalkyl substances (PFASs) and halogenated flame retardants (HFRs) – in 59 fish samples, collected in 2010 in 4 Spanish Rivers (Guadalquivir, Júcar, Ebro and Llobregat). Of the 135 CECs, 76 including 8 pharmaceuticals, 25 pesticides, 10 EDCs, 5 UV-filters, 15 PFASs and 13 HFRs were detected. Pharmaceuticals were the less frequently found and at lower concentrations. Pesticides, EDCs, UV-filters, PFASs and HFRs were det…
SIMILARITIES IN BIOACCUMULATION PATTERNS OF POLYCHLORINATED DIBENZO-p-DIOXINS AND FURANS AND POLYCHLORINATED DIPHENYL ETHERS IN LABORATORY-EXPOSED OL…
2003
Sediment and chironomid samples were collected from a river in the vicinity of and downstream from a closed chlorophenol production plant, and they were analyzed for polychlorinated dibenzo-p-dioxins and furans (PCDD/F) and polychlorinated diphenyl ethers (PCDE). Bioaccumulation of these compounds from the sediments by the oligochaeta, Lumbriculus variegatus, and semipermeable membrane devices (SPMDs) was studied in a 28-d bioaccumulation test. The sum concentrations of PCDD/Fs and PCDEs in sediments varied spatially, peaking at the site below the production plant, but the congener composition remained fairly constant throughout the river. The sum concentrations of chironomids, oligochaetes…
Integracja muzułmanów i kryzys migracyjny jako wyzwania dla niemieckiej i europejskiej dyplomacji
2016
W artykule przedstawiono problem integracji muzułmanów oraz konsekwencje współczesnego kryzysu migracyjnego, które stoją przed niemiecką i europejską dyplomacją. W odniesieniu do teoretycznych rozważań, przedstawiono koncepcje i modele polityki integracyjnej prowadzonej przez państwa zachodnioeuropejskie w warunkach przed kryzysem i obecnie. W opracowaniu zawarto krótki zarys historii napływu muzułmanów do Niemiec oraz procesy związane z ich integracją. Przedstawiono też główne cechy obecnego kryzysu, wskazując na wyzwania, jakie niesie dla całej Unii, a w szczególności dla Niemiec jako kraju najbardziej zaangażowanego w proces przyjmowania uchodźców i imigrantów. Zwrócono uwagę na podstawo…

La Gipsoteca del Dipartimento Culture e Società dell'Università degli Studi di Palermo. Storia e catalogo
2017
Il volume presenta, per la prima volta, la storia e il catalogo della Gipsoteca del Dipartimento Culture e Società dell’Università degli Studi di Palermo. Si tratta di un’importante raccolta di calchi in gesso di sculture antiche, voluta da Antonino Salinas (1841-1914) ai tempi del suo magistero accademico e ora completamente riordinata, grazie a un nuovo allestimento curato dallo stesso autore di questo libro. The volume presents, for the first time, the history and catalog of the Gipsoteca of the Culture and Society Department of the University of Palermo. This is an important collection of plaster casts of ancient sculptures, commissioned by Antonino Salinas (1841-1914) at the time of hi…
Idoneità lavorativa nel lavoratore alcolista o tossicodipendente
2011
Scopo del presente lavoro è l’analisi delle procedure e delle modalità di gestione del giudizio d’idoneità da parte del Medico Competente nei confronti dei lavoratori, con problemi di alcol o dipendenza da sostanze stupefacenti, che espletano mansioni ad elevato rischio infortunistico per se stessi e per terzi. Sono stati descritti gli steps secondo cui devono essere avviate le procedure anamnestiche e diagnostiche, necessarie ad identificare un lavoratore con problemi alcol e/o droga correlati. Abbiamo evidenziato le criticità della normativa di riferimento in tema di alcol ed in particolare le difficoltà operative del Medico Competente nell’effettuare i controlli alcolimetrici sui luoghi …
LC-ESI/HRMS analysis of glucosinolates, oxylipins and phenols in Italian rocket salad (Diplotaxis erucoides subsp. erucoides (L.) DC.) and evaluation…
2021
BACKGROUND: This study investigated the chemical profile and biological activity of Diplotaxis erucoides subsp. erucoides (L.) DC. (Brassicaceae) collected in Sicily (Italy). RESULTS: Liquid chromatography coupled with electrospray ionization and high-resolution mass spectrometry (LC-ESI/HRMS) analysis of the ethanol extract revealed the presence of 42 compounds – glucosinolates, hydroxycinnamic acids, flavonoids, and oxylipins. The extract was tested for its antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic) acid (ABTS), ferric reducing ability power (FRAP), and β-carotene bleaching tests. Promising protection from lipid peroxi…
The adenine nucleotide content of rat liver during infusions of carbohydrates and polyols
1972
Injection of large doses of fructose, sorbitol, or a mixture of glucose, fructose and xylitol in rats causes a drop of liver ATP, total adenine nucleotides and Pi and a rise of AMP, which is in agreement with data from the literature. These changes are considered as a transient disturbance of homeostasis by compounds which are rapidly phosporylated in the liver. This is confirmed by the fact that during continuous infusion of these and other compounds at doses of 1,5 g · kg−1 · h−1 there was no such change. It is concluded that infusions of fructose or of the other carbohydrates tested with rates not exceeding those recommended for parenteral nutrition (0,5 g · kg−1 · h−1) are not likely to…
