Erythrocytes of the Rhesus and Cynomolgus Monkeys.

The monograph Erythrocytes of the Rhesus and Cynomolgus Monkeys is devoted to the cytologic, quantitative, generative normal and abnormal presentations of the erythrocytes in these two species of primates...

n-TiO2 and CdCl2 co-exposure to titanium dioxide nanoparticles and cadmium: Genomic, DNA and chromosomal damage evaluation in the marine fish European sea bass (Dicentrarchus labrax).

Due to the large production and growing use of titanium dioxide nanoparticles (n-TiO2), their release in the marine environment and their potential interaction with existing toxic contaminants represent a growing concern for biota. Different end-points of genotoxicity were investigated in the European sea bass Dicentrarchus labrax exposed to n-TiO2 (1mgL(-1)) either alone and combined with CdCl2 (0.1mgL(-1)) for 7 days.

Anti-genotoxic ability of α-tocopherol and Anthocyanin to counteract fish DNA damage induced by musk xylene.

Many compounds released into the environment are able to interact with genetic material. The main purpose of genetic toxicology is to investigate the adverse effects of genotoxic molecules such as reduced fitness, changes in gene frequencies and their impact on genetic diversity in populations following genotoxic exposure. However, the ecological effects of many genotoxic compounds remain poorly understood.

Genomic and chromosomal damage in the marine mussel Mytilus galloprovincialis: Effects of the combined exposure to titanium dioxide nanoparticles and cadmium chloride.

Titanium dioxide nanoparticles (TiO2-NPs) continuously released into waters, may cause harmful effects to marine organisms and their potential interaction with conventional toxic contaminants represents a growing concern for biota. We investigated the genotoxic potential of nanosized titanium dioxide (n-TiO2) (100 μg L(-1)) alone and in combination with CdCl2 (100 μg L(-1)) in Mytilus galloprovincialis after 4 days of in vivo exposure. RAPD-PCR technique and Micronucleus test were used to study genotoxicity.

Genotoxicity assessment of TiO2 nanoparticles in the teleost Danio rerio.

Titanium dioxide nanoparticles (TiO2 NPs), widely used in paints, pharmaceutical preparations and in many consumer products, have been shown to induce cytotoxicity, genotoxicity and carcinogenic responses both in vitro and in vivo. Numerous studies have shown the potential impact of nanoparticles on a series of aquatic organisms and their toxicity has been linked to their dissolution, surface properties and size. In vitro studies have raised concerns about the toxicity of TiO2 NPs, but there are very limited data on ecotoxicity to aquatic life.
