Hazard characterization of Alternaria toxins to identify data gaps and improve risk assessment for human health.

epoxide-bearing analogs ATX- II, ATX- III, and STTX- III show the highest cytotoxic, genotoxic, and mutagenic potential in vitro. Under hormone-sensitive conditions, AOH and AME act as moderate xenoestrogens, but ...

Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide

modelling. Agglomerate size as a nanodescriptor was well associated with biological endpoints such as DNA damage and/or cytotoxicity. We conclude that, agglomerate size is an important nanodescriptor to assess ...

Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo

exposed to these suspensions for 24 h and endpoints such as cytotoxicity, total glutathione, epithelial barrier integrity, inflammatory mediators and DNA damage were measured. Large agglomerates of 17 nm ...

In Vitro and In Vivo Toxicity Studies on Cymbopogon giganteus Chiov. Leaves Essential Oil from Benin

a single dose of 5% or 2% v/v. Single doses of 0.125% or 0.5% v/v did not induce inflammation, cell recruitment nor cytotoxicity in lungs 3 h or 24 h after administration, suggesting safety at these ...

Is aggregated synthetic amorphous silica toxicologically relevant?

far, it is indeed believed that large aggregates represent a weaker hazard compared to their nano counterpart. Thus, we assessed the impact of SAS aggregation on in vitro cytotoxicity/biological activity ...

Increased surface area of halloysite nanotubes due to surface modification predicts lung inflammation and acute phase response after pulmonary exposure in mice

clear. We assessed the toxicological response to HNT s (NaturalNano (NN)) before and after surface etching (NN-etched). Potential cytotoxicity of the two HNT s was screened in vitro in MutaTMMouse lung ...

In vitro toxicity, genotoxicity and antigenotoxicity of Nigella sativa extracts from different geographic locations

Number 141 (2019) Keywords: antigenotoxicity cytotoxicity genotoxicity Geographic location Nigella sativa Seed extracts Abstract: Nigella sativa or black cumin is used as a spice and as a natural remedy ...

Phytochemical analysis, antioxidant, anticoagulant and in vitro toxicity and genotoxicity testing of methanolic and juice extracts of Beta vulgaris L.

genotoxicity or cytotoxic effects. The results show the potential of the plant, especially the juice, as a new source of bioactive molecules for therapeutic purposes, possibly in the treatment of ...
