Mutagenic pollution of environment is a global and important problem. This includes marine environment. Although many mutagenicity assays have been developed, there are specific problems with testing marine water and sediments for mutagenic contamination. One of them is the fact that most of genetically modified strains used in commonly available microbiological mutagenicity assays, like Escherichia coli or Salmonella, survive relatively poorly in marine waters, especially those of higher salinity. Thus, alternative assays have been developed, in which bacteria occurring naturally in marine habitats are employed. These assays, reviewed in this article, appear to be useful in testing not only marine samples but also can be used in other approaches, which involve detection and estimation of the amount of mutagenic compounds.

The venom of Ectatomma brunneum is considered promising for drugs development. Therefore, it is important to evaluate its toxic potential and genetic instability using biological assays. To this end, toxicity assays were performed with Artemia salina, cytotoxicity and genotoxicity with Allium cepa and mutagenicity with Ames.

It has been documented that D-dimer levels have potential utility as a measure of tumor activity in diffuse large B-cell lymphoma (DLBCL), however whether it can be used as a predictive marker of treatment outcome has not been established. This study means to retrospectively evaluate the role of D-dimer in prediction of treatment efficacy in patients with DLBCL. 151 patients with newly diagnosed DLBCL were enrolled.

There has been a shift from traditional animal models towards alternative methods. While 2D cell culture has a decade long tradition, more advances methods like 3D cultures, organoids, and co-culture techniques, which better mimic in vivo conditions, are not yet well established in every research area. Genotoxicity assessment is an integral part of toxicological testing or regulatory approval of pharmaceuticals and chemicals.

Photodegradation of azilsartan yields a phenanthridine derivative (APP). We suspected that APP could be a DNA-reactive substance, since many phenanthridine derivatives are mutagenic. In silico quantitative structure-activity relationship analysis indicated potential mutagenicity of APP, due to DNA reactivity at the 6-aminophenanthridine moiety.

We have studied the presence and frequency of micronuclei in exfoliated oral mucosa cells of full-term newborns and their association with maternal prenatal factors. We report an analytical, observational, cross-sectional, prospective study that includes 97 preterm infants (<37 weeks), 37 newborns from mothers with comorbidities, and 60 newborns from mothers without comorbidities, in a tertiary public hospital. Oral mucosa cells were collected within 24 h after birth.
