Effect of sodium dodecyl sulfate (SDS) on stress response in the Mediterranean mussel (Mytilus Galloprovincialis): Regulatory volumedecrease (Rvd) an…
2014
In this study the effects of an anionic surfactant, sodium dodecyl sulfate (SDS), are assessed on the Mediterranean mussel (. Mytilus galloprovincialis), exposed for 18 days at a concentration ranging from 0.1. mg/l to 1. mg/l. The effects are monitored using biomarkers related to stress response, such as regulatory volume decrease (RVD), and to oxidative stress, such as reactive oxygen species (ROS), endogenous antioxidant systems and Hsp70 levels. The results demonstrate that cells from the digestive gland of M. galloprovincialis, exposed to SDS were not able to perform the RVD owing to osmotic stress. Further, SDS causes oxidative stress in treated organisms, as demonstrated by the incre…
Levels of dioxin-like polychlorinated biphenyls (DL-PCBs) and metals in European sea bass from fish farms in Italy
2012
The study evaluated the levels of dioxin-like polychlorinated biphenyls (DL-PCBs) and metals in the fillet of medium (468 ± 92 g) and large (708 ± 135 g) European sea bass (Dicentrarchus labrax) from 11 Italian fish farms using different rearing systems. DL-PCB contamination was higher in fish grown in extensive coastal lagoons compared with intensive inland basins and intensive sea cages (28.5 vs. 9.13 and 13.1 pg Toxic Equivalents (TEQ)/g fat; P < 0.001). Copper concentrations were lower (0.810 vs. 0.993 and 1.071 mg/kg fw) and mercury was higher (0.025 vs. 0.006 and 0.003 mg/kg fw) (P < 0.001) in sea bass from extensive farms than from intensively farmed fish in inland or sea cage system…

THE ANABOLIC-ANDROGENIC STEROIDS EXERT DIRECT TOXIC EFFECTS ON NEURON-LIKE CELLS
2012
INTRODUCTION Intake of AAS by atheletes and others in an attempt to gain muscle strength and improve perfor- mance is often associated with toxic effects on the liver, the cardiovascular system, the male and female reproductive systems, and the central nervous system (Trifunovic et al., 1995). In vivo administration of high doses of androgens has been linked to neurobehavioral changes that could be the outward manifestation of neuronal damage. METHODS PC12 cells are a cell line that have been widely used as a model in neurobiological investigations (Fujita et al., 1989; Vaudry et al., 2002). Following exposure to nerve growth factor (NGF), PC12 cells differentiate into a sympathetic-like ne…

STUDIO DEI MECCANISMI DI MORTE CELLULARI INDOTTI DAL CANNABINOIDE SINTETICO WIN IN CELLULE TUMORALI IN COLTURA
2014
Per lungo tempo, i cannabinoidi sono stati considerati come farmaci lenitivi ma non curativi della patologia cancerosa. Tuttavia, negli scorsi anni, è stata suggerita una potenziale applicazione dei cannabinoidi come droghe antitumorali, anche se il loro meccanismo d’azione non è ancora ben conosciuto. Gli obiettivi di questo studio sono stati: - la valutazione degli effetti del cannabinoide sintetico WIN55,212-2 (WIN) su differenti linee di cellule tumorali in coltura (cellule di carcinoma colorettale HT29 e cellule di osteosarcoma umano MG63) e – la valutazione dei meccanismi molecolari indotti dal trattamento con il cannabinoide. I risultati riportati indicano che in entrambe le linee ce…
