Genotoxicity of water extracts from hypoxis species
cytotoxicity of these samples was established by determining their NI50 values (50% inhibition of NRU), and these results were used for dose-finding in genotoxicity tests. None of the tested extracts were ...
Mutagenicity, antimutagenicity and cytotoxicity evaluation of South African Podocarpus species
cytotoxicity of the extracts was assessed by determining their NI (50) values (50% inhibition of NRU). RESULTS: The extracts did not show any mutagenic effects against all the tester strains with or without ...

Quality of laboratory studies assessing effects of Bt-proteins on non-target organisms: minimal criteria for acceptability
of criteria determining their relevance and reliability. As a case-study, this exercise revealed that when not all quality criteria are met, weighing the robustness of the study and its relevance for ...
Biodiversity and human health: mechanisms and evidence of the positive health effects of diversity in nature and green spaces.
mortality. The presence, accessibility, proximity and greenness of green spaces determine the magnitude of their positive health effects, but the role of biodiversity (including species and ecosystem ...
Determination of lawasone and paraphenylenediamine in henna tattoos and hair dyes through UPLC-PDA
presence of the skin sensitizer paraphenylenediamine (PPD). Aim: To develop and validate a fast UPLC- PDA method to simultaneously determine lawsone and PPD in henna tattoos and hair dyes with the purpose to ...
Urban environment and mental health: the NAMED project, protocol for a mixed-method study.
associations between the urban residential environment and mental health, taking respondents’ socioeconomic status and physical health into account. Mental health is determined by the mental health indicators in ...
