Journal of Applied Toxicology, EarlyView.ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

Limnology and Oceanography: Methods, EarlyView.Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

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Toxicology, EarlyView.ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022.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

Atomic Force Microscopy Images Label-Free, Drug Encapsulated Nanoparticles In Vivo and Detects Difference in Tissue Mechanical Properties of Treated and Untreated: A Tip for Nanotoxicology [PDF]
, 2013 Overcoming the intractable challenge of imaging of label-free, drug encapsulated nanoparticles in tissues in vivo would directly address associated regulatory concerns over 'nanotoxicology'. Here we demonstrate the utility of Atomic Force Microscopy (AFM)

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models
Environmental Toxicology, EarlyView.ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...
