If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

To make the right clinical decisions or develop effective diagnostic tests and treatments, it is important to understand the underlying mechanisms of a condition or behavior.

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…

The project GRADIENTS investigates what it meant to be European in colonial Africa where identification as European often did not depend on skin colour and was understood on a spectrum with many gradients.

Why does social anxiety increase in adolescence and how does it grow out of control in some adolescents?
