Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Buccal Micronucleus Cytome Assay- A Biomarker of Genotoxicity

, 2015
The buccal micronucleus cytome assay in exfoliated buccal cells is utilized as biomarkers for DNA damage, cell death and basal cell frequency. It offers great opportunity to evaluate genotoxicity by the way of quantifying mean frequencies of micronuclei,

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

Environmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Cellular Effects of Naringin in Prevention of Genotoxicity Caused by Mifepristone on Human Blood Lymphocytes

Journal of Mazandaran University of Medical Sciences, 2018
Background and purpose: Mifepristone is an oral synthetic steroid with antiglucocorticoid and antiprogesterone activities. Therefore, it could be dangerous during pregnancy since it causes cytogenetic damage and, consequently, abortion.

Biosafety Evaluation of 6,7-Dihydroxy-3-(2-Nitrophenyl)Coumarin in Human Cells. [PDF]

J Appl Toxicol
ABSTRACT Coumarins are considered a privileged scaffold in medicinal chemistry, as they may interact with biological macromolecules, presenting several pharmacological properties. Their potential makes them an object of study for the evaluation of their safety for humans, which is essential in the design of a potential drug.
