A study by researchers at Institute of Environmental Medicine shows that in vitro new approach methodologies (NAMs) can be a useful tool to improve cancer risk assessment (CRA) strategies in the context of complex environmental mixtures as such air pollution.

EU's new Partnership for the Assessment of Risks from Chemicals (PARC) is a 7-year partnership, aimed at reducing exposure to hazardous chemicals and their effects on human health and the environment.

Every day, people are exposed to large number of pollutants, but the problem of how to assess the dangers of the chemical “cocktail effect” has long frustrated both scientists and public authorities. A collaborative study involving researchers from Karolinska Institutet published in the journal Science now presents a new strategy that combines population studies with experiments using cell and animal models.

Children born to women who underwent gastric bypass surgery before becoming pregnant had a lower risk of major birth defects than children born to women who had severe obesity at the start of their pregnancy. That’s according to a matched cohort study by researchers at Karolinska Institutet and Örebro University published in the scientific journal JAMA. The findings indicate that weight-loss and improved blood sugar control could reduce the risk of major birth defects.
