To maintain nutritional homeostasis, external food-related stimuli have to be evaluated in relation to the internal states of hunger or satiety. To examine the neural circuitry responsible for integration of internal and external determinants of human eating behaviour, brain responses to visual and complex gustatory food-related stimuli were measured using(More)
OBJECTIVE The authors sought to identify neural correlates of eating disorders in order to contribute to the debate on the genesis and classification of eating disorders and provide endophenotypes for genetic research. METHOD Twenty-six female patients with eating disorders (10 with bulimia nervosa, 16 with anorexia nervosa) and 19 healthy female(More)
BACKGROUND Previous Magnetic Resonance Imaging (MRI) studies of people with anorexia nervosa (AN) have shown differences in brain structure. This study aimed to provide preliminary extensions of this data by examining how different levels of appetitive restraint impact on brain volume. METHODS Voxel based morphometry (VBM), corrected for total(More)
Faeces samples were collected from 302 untreated calves on the day of onset of diarrhoea and from 49 healthy calves at 32 farms experiencing outbreaks of diarrhoea. At least four diarrhoeic calves were sampled on each farm, and samples were examined for rotavirus, coronavirus, cryptosporidium, enterotoxigenic Escherichia coli and Salmonella species.(More)
Increased physical activity and decreased motivation to eat are common features in anorexia nervosa. We investigated the development of these features and the potential implication of brain-derived neurotrophic factor (BDNF) and dopaminergic signalling in their development in C57BL/6J and A/J inbred mice, using the 'activity-based anorexia' model. In this(More)
BACKGROUND Abnormalities in perception and evaluation of body shape are a hallmark of eating disorders. METHODS Brain responses to line drawings of underweight, normal weight, and overweight female bodies were measured with functional magnetic resonance imaging in 9 women with bulimia nervosa, 13 with anorexia nervosa, and 18 healthy women. Participants(More)
Calf fecal rotavirus strains were serotyped in enzyme-linked immunosorbent assays, using monoclonal antibodies to the VP7s of serotypes 1, 2, 3, 5, and 6 and to the VP4 of B223 (designated serotype 10). Sixty-six percent of 162 samples were typed as serotype 6, and 7% were serotyped as serotype 10. Most of the untyped strains did not react with a monoclonal(More)
BACKGROUND Previous fMRI studies show that women with eating disorders (ED) have differential neural activation to viewing food images. However, despite clinical differences in their responses to food, differential neural activation to thinking about eating food, between women with anorexia nervosa (AN) and bulimia nervosa (BN) is not known. METHODS We(More)
BACKGROUND Patients with eating disorders favor immediate gratification and ignore long-term negative consequences. This study investigated decision making in bulimia nervosa using the Iowa Gambling Task (IGT) and skin conductance responses (SCR). METHOD A total of 26 bulimia nervosa patients and 51 healthy controls took part in this study; 29 patients(More)
BACKGROUND Women with anorexia nervosa (AN) have aberrant cognitions about food and altered activity in prefrontal cortical and somatosensory regions to food images. However, differential effects on the brain when thinking about eating food between healthy women and those with AN is unknown. METHODS Functional magnetic resonance imaging (fMRI) examined(More)
