Besides the European Union (EU) Regulation on Registration, Evaluation, Authorization and Restriction of CHemicals (REACH), the EU Water Framework Directive (WFD) is probably the single most important piece of environmental legislation in Europe when it comes to dealing with nanomaterials in the future given their widespread and dispersive use. Despite of the importance of the WFD, the WFD has ...

BACKGROUND Chemical carcinogenesis bioassays in animals have long been recognized and accepted as valid predictors of potential cancer hazards to humans. Most rodent bioassays begin several weeks after birth and expose animals to chemicals or other substances, including workplace and environmental pollutants, for 2 years. New findings indicate the need to extend the timing and duration of expos...

Few risk factors for nonsuicidal self-injury (NSSI) have been identified. This study investigated diminished aversion toward self-injury (i.e., NSSI, suicide/death stimuli) and self-criticism as unique NSSI risk factors. After terminating a treatment study, 154 adults with a recent and frequent NSSI history completed self-report and computer-based measures of psychopathology, implicit and expli...
