Introduction: Growing evidence indicates that identity-based victimization (IBV; e.g., discrimination) is traumatic, and associated with mental health and academic concerns.

With a diverse high school sample (n = 645; 55% female; 61% White, 18% African American, 10% Latino, 10% Asian American, 1% Multiracial), patterns of experiences with marginalization and connection were identified and their associations with achievement and mental health examined. Using two-step cluster analysis, three clusters were identified: above the fray, exposed and protected, and targeted and unsupported.

While the current regulatory requirement for substances of concern, such as MWCNTs, in many jurisdictions is a 90-day rodent inhalation test, the monetary, ethical, and scientific concerns associated with this test led an international expert group to convene in Washington, DC, USA, to discuss alternative approaches to evaluate the inhalation toxicity of MWCNTs. Pulmonary fibrosis was identified as a key adverse outcome linked to MWCNT exposure, and recommendations were made on the design of an in vitro assay that is predictive of the fibrotic potential of MWCNTs.

An extensive review was conducted on aerosol generation and exposure apparatus as part of an international expert workshop convened to discuss the design of an in vitro testing strategy to assess pulmonary toxicity following exposure to aerosolized particles. More specifically, this workshop focused on the design of an in vitro method to predict the development of pulmonary fibrosis in humans following exposure to multi-walled carbon nanotubes (MWCNTs).
