(author), TNO Kwaliteit van Leven (author)Background: Besides short stature, gonadal dysgenesis leading to a lack of oestrogen is one of the main characteristics of Turner syndrome (TS). In most TS girls, puberty is induced with exogenous oestrogens.

(author), TNO Kwaliteit van Leven (author)Background: The brain plays a crucial role in the decision to eat, integrating multiple hormonal and neural signals. A key factor controlling food intake is selective satiety, ie, the phenomenon that the motivation to eat more of a food decreases more than does the motivation to eat foods not eaten. Objective: We investigated the effect of...article 2006

Hypercholesterolaemia is initially treated by diet. However, most studies of diet and cholesterol response have been carried out in men, and it is not known whether women react to diet to the same extent as men do. We therefore studied sex differences in the response of serum cholesterol and lipoproteins to diet. Materials and...article 1999
