Application
- Insights into the mechanisms of within-species variation in sensitivity to chemicals: A case study using daphnids exposed to CMIT/MIT biocide.: This study investigates the differential sensitivity of daphnids to 2-Methyl-4-isothiazolin-3-one, highlighting the biochemical mechanisms underlying these variations. The findings provide crucial insights for environmental safety assessments (Kim et al., 2023).
- Effects of the biocide methylisothiazolinone on Xenopus laevis wound healing and tail regeneration.: The study assesses the impact of 2-Methyl-4-isothiazolin-3-one on regenerative processes in amphibians, contributing to the understanding of its biological effects and potential toxicity (Delos Santos et al., 2016).
- T cell lymphomatoid contact dermatitis: a challenging case and review of the literature.: This review includes discussions on 2-Methyl-4-isothiazolin-3-one-induced contact dermatitis, providing valuable information for dermatological applications and safety assessments (Knackstedt and Zug, 2015).
