Body dissatisfaction and its interrelations with other risk factors for bulimia nervosa in 12 countries.

Background: It is widely accepted that risk factors for bulimia nervosa, mainly body dissatisfaction, are dependent on cultural factors. However, to date few studies have compared data from different cultures with an appropriate methodology. Therefore we aimed to gather reliable information on body dissatisfaction and other risk factors for bulimia from different nations and to reveal their functional interrelations.

Improved athletic performance in highly trained cyclists after interval training.

This study determined whether a 4-wk high-intensity interval training program (HIT) would improve the 40-km time trial performances (TT40) of 8 competitive cyclists (peak O2 uptake 5.2 +/- 0.4 I.

Regulation of bradykinin-induced chloride secretion in a human epithelial cell line.

The chloride secretory response to bradykinin in T84 cells is regulated. The efflux rate of 125I from these cells can be used to measure this response, and to demonstrate that the sensitivity to bradykinin varies with time in culture. The response in NuT84 cells is greater than that in T84, and can be blocked by the B2 receptor antagonist HOE-140.
