Fat Talk in College Women
2022
This study placed the phenomenon of college women’s fat talk within response styles theory. We predicted that with increasing trait body dissatisfaction there would be an increase in rumination leading to a greater frequency of fat talk. We also predicted that neuroticism would moderate this mediation pathway, and that these effects would occur over and above body size. A survey was conducted on a convenience sample of 212 college women with a mean age of 22.04 years ( SDage = 2.61). A bootstrap analysis utilizing PROCESS software supported the predicted moderated-mediation model. Thus, those college women higher in both trait body dissatisfaction and neuroticism would experience greater r…
Effects of acute administration of bupropion on behavior in the elevated plus-maze test by NMRI mice
2004
Bupropion attenuates some symptoms of nicotine abstinence, although its effects on anxiety are unclear. The present study investigates acute effects of bupropion (5, 10, 20 and 40 mg/kg) on anxiety as expressed in the elevated plus-maze test in male NMRI mice. Given the influence of locomotion in this test, effects of bupropion were also evaluated in an actimeter. Spontaneous motor activity remained significantly increased in mice treated with 10, 20 and 40 mg/kg of bupropion during the 60 min recorded. Results from the elevated plus-maze showed that 20 mg/kg increased total arm entries and 40 mg/kg increased total and open arm entries. Although the increase in the number of visits to the o…
Sexual dysfunction in hypertensive patients treated with losartan.
2001
ABSTRACT Background Impaired erectile function in men is a component of the dysmetabolic syndrome of high blood pressure as well as a sequela of antihypertensive therapy. This prospective interventional study in men with uncontrolled hypertension (blood pressure ≥ 140/90 mm Hg) used a survey instrument to assay sexual dysfunction before and after therapy with losartan. Methods We evaluated the influence of a 12-week therapy with losartan in 82 hypertensive subjects with (n = 82) and without (n = 82) a diagnosis of erectile dysfunction using a self-administered questionnaire validated in another 60 subjects with hypertension. Results: From an initial sample of 323 hypertensive men and women,…
Effects of co-administration of bupropion and nicotinic agonists on the elevated plus-maze test in mice
2005
There is evidence that the cholinergic nicotinic system is involved in the modulation of anxiety. Anxiolytic and anxiogenic effects of nicotine agonists have been reported in mice. Bupropion is an antidepressant drug which may alleviate some symptoms of nicotine withdrawal, although its effects on anxiety are not clear. It has been suggested that the interaction between bupropion and nicotinic mechanisms could be complex. The aim of the present study was to investigate acute effects of co-administration of bupropion and nicotinic agonists on the elevated plus-maze test in NMRI mice. Effects of nicotine, lobeline, and cytisine (0.35 and 0.175 mg/kg), administered alone or combined with bupro…
Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting
2019
The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was …
Bupropion induced changes in exploratory and anxiety-like behaviour in NMRI male mice depends on the age
2013
The aim of this study was to assess the effects of the antidepressant bupropion on anxiety and novelty-seeking in adolescent mice of different ages and adults. Behavioural differences between early adolescent, late adolescent and adult NMRI mice were measured both in the elevated plus-maze and the hole-board tasks following acute administration of bupropion (5, 10, 15, 20 mg/kg) or saline. In the plus maze test, early and late adolescent mice treated with bupropion (10, 15 mg/kg, respectively) had lower percentages of entries in the open-arms compared to their vehicle controls. Adult mice treated with bupropion did not differ from their vehicle controls. These results suggest that the effec…
Semantic traffic applications based on DatexII
2009
In this work we demonstrate a particular use of ontologies based on the European specifications DATEXII. These specifications are designed and developed as a traffic and travel data exchange mechanism by a European task force to set up and standardise the interface between traffic control and information centres. It is the reference for applications that are developed and implemented in Europe.This language describes concepts and structures of data related to traffic, but the description is just syntactic, not semantic. Therefore the objective to be reached in this part of the research has been to develop a semantic description in order to carry out some applications like syndication and a …
Effects of acute bupropion administration on locomotor activity in adolescent and adult mice
2005
Responses to some psychoactive substances seem to differ between adolescents and adults. Bupropion, an antidepressant which is also used for smoking cessation, induces a dose-dependent increase in locomotor activity in adult mice, although its behavioral actions in adolescents have not been evaluated. In the present study the effects of acute bupropion administration (5, 10, 15 and 20 mg/kg) on locomotor activity were examined in early adolescent (postnatal day (pnd): 29-31 days), late adolescent (pnd: 47-49 days) and adult (pnd > 70 days) male NMRI mice, using an infrared photocell system. Locomotion was recorded for a total period of 90 min. Results indicated that there were significant d…
