We measured the concentrations of alpha-melanocyte-stimulating hormone (alpha-MSH) in various brain regions as well as in the pituitary gland and plasma of the toad Bufo speciosus during a 24-hr light:dark cycle. There was significant diurnal variation of alpha-MSH concentrations in the hypothalamus and brainstem. In both areas alpha-MSH concentrations were(More)
This study was designed to evaluate the traditional advice to headache sufferers to avoid all triggers ('Avoidance'), and a novel approach to trigger management (Learning to Cope with Triggers - 'LCT') that included graduated exposure to selected triggers to promote desensitization. Individuals (84F, 43M) with migraine and/or tension-type headache were(More)
OBJECTIVE Understanding socio-cultural factors associated with the development of dieting tendencies is important for preventing future disordered eating. We explored individual and socio-cultural factors associated with weight-focussed dietary restraint tendencies (described as dietary restraint) in 5-year-old girls. METHOD Participants were 111(More)
BACKGROUND Body size attitudes and body image form early in life, and understanding the factors that may be related to the development of such attitudes is important to design effective body dissatisfaction and disordered eating prevention interventions. This study explored how fathers' and mothers' body size attitudes, body dissatisfaction, and dietary(More)
Dieting is a risk factor for the development of eating disorders , and research suggests that dietary restraint emerges from a young age. There is a need to understand factors associated with the development of dieting intentions to prevent later disordered eating. The aim of this research was to explore individual and sociocultural factors related to(More)
Relationships between the body size attitudes of fathers and mothers and those of their four-year-old sons and daughters Despite evidence that parents can influence the development of body dissatisfaction and disordered eating in older children and adolescents, few studies have examined relationships between parents' body size attitudes and related(More)
Very little is known about the development of body size attitudes in young children. We examined weight attitudes in 279 4-year-old girls and boys to test the hypothesis that children hold stereotypical beliefs about others based on body size, and that both child and maternal body image variables are related to these attitudes. Children completed an(More)
We investigated the potential influence of opioid and melanotropic peptides on endogenous norepinephrine (NE) release from the A2 noradrenergic cell group of rats using a static, fixed-volume incubation procedure. Norepinephrine release from slices of caudal dorsomedial medulla (CDMM) was evoked by high potassium concentrations (20 and 60 mM) in a(More)
Maternal nutrition during pregnancy can affect kidney development in the foetus, which may lead to adverse consequences in the mature kidney. It was expected that high-salt intake by pregnant ewes would lead to a reduction in foetal glomerular number but that the ovine kidney would adapt to maintain homoeostasis, in part by increasing the size of each(More)
Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3-year-old children and their parents, who provided data at baseline and 1 year later. Parents completed self-report body size attitude and dieting measures. Child weight(More)
