Continuous release of nanoparticles (NPs) into marine coastal environments results in an increased risk of exposure to complex NP mixtures for marine organisms. However, to date, the information on the effects at molecular and biochemical levels induced by the exposure to NPs, singly and as a mixture, is still scant. The present work aimed at exploring the independent and combined effects and the mechanism(s) of action induced by 7-days exposure to 1 μg/L nZnO, 1 μg/L nTiO and 1 μg/L FC fullerene in the Manila clam Ruditapes philippinarum, using a battery of immunological and oxidative stress biomarkers in haemolymph, gills and digestive gland.

Nanoplastics (NPs) as emerging marine pollutants can be taken up by seafood organisms. It is crucial to quantitatively assess NP's distribution behavior in organisms to elucidate concentration dependent biological effects. Such a knowledge gap has remained due to the lack of reliable NP models and analytical methods. Read More

During the decommissioning and removal of radioactive material in nuclear facilities, fine, tritiated dusts of stainless steel, cement or tungsten are generated that could be accidentally released to the environment. However, the potential radio- and ecotoxicological effects these tritiated particles may have are unknown. In this study, stainless steel particles (SSPs) representative of those likely to be tritiated are manufactured by hydrogenation and their tissue-specific bioaccumulation, release (depuration) and subsequent genotoxic response have been studied in the marine mussel, Mytilus galloprovincialis, as a baseline for future assessments of the potential effects of tritiated SSPs.

Background/aims: The aim of the present study was to investigate whether α-lipoic acid (ALA) could reverse/prevent high fat diet (HFD) -induced salivary gland dysfunction and oxidative damage in the salivary glands of rats, and strengthen their antioxidant defense.

Methods: The enzymatic and non-enzymatic antioxidants as well as their redox status, oxidative damage products and salivary flow rate were investigated in the parotid (PG) and submandibular (SMG) glands of Wistar rats exposed to a high-fat diet and then supplemented with ALA for a period of 4 weeks. The rats in the study were divided into 4 groups of 10 animals each: C (control), HFD,
C + ALA, HFD + ALA. Read More
