Última Different levels of brain-derived neurotrophic factor and cortisol in healthy heavy smokers BJMBR Neves,C.D.C.; Lacerda,A.C.R.; Lima,L.P.; Lage,V.K.S.; Balthazar,C.H.; Leite,H.R.; Mendonça,V.A.. Studies suggest that brain-derived neurotrophic factor (BDNF) and the hypothalamic-pituitary-adrenal (HPA) axis modulate dopaminergic activity in response to nicotine and that the concentrations of BDNF and cortisol seem to be dependent on the amount and duration of smoking. Therefore, we investigated BDNF and cortisol levels in smokers ranked by daily cigarette consumption. Twenty-seven adult males (13 non-smokers and 14 smokers) participated in the study. The smokers were divided in two groups: light (n=7) and heavy smokers (n=7). Anthropometric parameters and age were paired between the groups, and plasma BDNF and salivary cortisol levels were measured. Saliva samples were collected on awakening, 30 min after awakening, at 10:00 and 12:00 am, 5:00 and...

Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (including ethanol), but the consequences of stress and ethanol in the organism when these factors are concomitant results in a complex interaction. We investigated the effects of concomitant, chronic administration of ethanol and stress exposure on the withdrawal and consumption of, as well as the preference for, ethanol in mice. Male Swiss mice (30–35 g, 8-10 per group) were exposed to an ethanol liquid... Tipo: Info:eu-repo/semantics/article Palavras-chave: Ethanol; Addiction; Stress; Free-bottle choice; Withdrawal.

Behavioral economists maintain that addictions such as alcoholism, smoking and over-eating represent examples of present-bias in decision making that is fundamentally irrational. In this article, we develop a model of present bias and apparently hyperbolic discounting that is fully consistent with rational behavior. We construct an experiment to test our hypothesis and to determine whether discount rates differ for individuals who engage in behaviors that could endanger their health. Our results show that discount functions are quasi-hyperbolic in shape, and that obesity and drinking are positively related to the discount rate. Anti-obesity policy, therefore, would be best directed to informing individuals as to the long-term implications of short-term...

Ano: 2010 URL: http://purl.umn.edu/61186 Obesity and Nutrient Consumption: A Rational Addiction? AgEcon Richards, Timothy J.; Patterson, Paul M.; Tegene, Abebayehu. Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically. Consequently, any explanation of obesity must address the reason why consumers tend to overeat in spite of somewhat obvious future health implications. This study tests for an addiction to food nutrients as a potential explanation for the obesity epidemic. Specifically, we use a random coefficients (mixed) logit model applied to household scanner data to test a multivariate version of the rational addiction model of Becker and Murphy and Chaloupka. We find evidence... Tipo: Working or Discussion Paper Palavras-chave: Addiction; Demand; Mixed logit; Nutrients; Obesity.; Food Consumption/Nutrition/Food Safety.

Ano: 2010 URL: http://purl.umn.edu/116410 Fast Food, Addiction, and Market Power AgEcon Richards, Timothy J.; Patterson, Paul M.; Hamilton, Stephen F.. Many attribute the rise in obesity since the early 1980's to the overconsumption of fast food. A dynamic model of a different-product industry equilibrium shows that a firm with market power will price below marginal cost in a steady-state equilibrium. A spatial hedonic pricing model is used to test whether fast food firms set prices in order to exploit their inherent addictiveness. The results show that firms price products dense in addictive nutrients below marginal cost, but price products high in nonaddictive nutrients higher than would be the case in perfect competition.
