Peer pressure to “Fat talk”: Does audience type influence how women portray their body image?

“Fat talk” describes women discussing their bodies disparagingly for impression management while interacting with one another. This study examined whether college females deliberately alter their self-reported body image according to characteristics of their prospective audience. This study was a mixed experimental design with four audience conditions (private, public, female audience, male audience) as the between-subjects factor and time across trials as the within-subjects factor using college females as participants (N = 100). Pre versus posttest changes on the Body Esteem Scale (BES) and the Body Weight Figure Assessment (BWFA) served as the dependent variables. It was hypothesized that body image would decrease to indicate self-derogation (fat talk) in the public audience and female audience conditions, whereas body image would increase in the male audience condition. These hypotheses were not supported using repeated measures ANOVA. Strengths and weaknesses of the study are discussed

Psychological, nutritional, and energy expenditure differences in college females with anorexia nervosa vs. comparable-mass controls

This is the first study to examine psychological and behavioral variables in nonhospitalized college females with subclinical anorexia nervosa (AN) as compared to healthy college females of comparable body mass (i.e., body mass index (BMI)<19). Participants who met all DSM-IV [Diagnostic and statistical manual of mental disorders, 4th ed. (1994). Washington, DC: APA.] criteria for AN-restrictive type (except for BMI<17.5; n=11) and control participants (n=15) with comparable body mass completed psychological, nutritional, and exercise assessments. Results suggested that those with AN evidenced more general psychopathology, more eating disorder symptoms, more dieting, more compulsive exercise, and less consumption of calories compared to participants in the control group. There was no difference in macronutrient consumption. There was no significant difference in expenditure of energy, despite differences in reports of compulsive exercise. Given similar body mass, this suggests that the women with AN were experiencing an energy deficit consistent with the disorder's defining features of “fear of gaining weight or becoming fat” and provides us with more understanding of individuals with AN in their natural environment

Do Animated Disney Characters Portray and Promote the Beauty–Goodness Stereotype?

The films of Walt Disney have served as icons of childhood over the last century. The Disney Corporation’s success is evidenced in its financial fortitude. In 1995, Walt Disney Company had the biggest market share, relative to the number of releases, at 19% (Smith & Thompson, 1996). In 1997, Disney had sales of nearly $24 billion. This made Disney the world’s second largest media firm behind Time Warner. As of mid-2007, Disney was a Dow 30 company, with annual revenues of nearly$34 billion in its previous fiscal year (“Disney Acquires Club Penguin,” 2007). Films for children contribute hundreds of millions of dollars to Disney annually (Robertson, 1998). One researcher suggested that Disney films inspire at least as much cultural authority and legitimacy for teaching specific roles, values, and ideals than more traditional sites of learning, such as public schools, religious institutions, and the family (Giroux, 1995). Their popularity among children and adults has led a handful of researchers to assess character portrayals within these films. For instance, Robinson, Callister, Magoffin, and Moore (2007) recently evaluated Disney’s portrayal of the elderly

Fat talk and self-presentation of body image: Is there a social norm for women to self-degrade?

The current investigations build upon previous ethnographic research, which identified a social norm for adolescent females to engage in “fat talk” (informal dialogue during which individuals express body dissatisfaction). In Study 1, participants were shown a vignette involving women engaging in fat talk dialogue and were subsequently asked to chose one of three self-presentational responses for a target female: (1) self-accepting of her body, (2) providing no information, or (3) self-degrading about her body. Male and female participants believed the target would be most likely to self-degrade, and that this would lead women to like her, while the self-accepting response would lead men to like her most. Study 2 used the same vignette but participants were asked to respond in an open-ended fashion. Participants again expected the target female to self-degrade. The present findings suggest college students perceive fat talk self-degradation of body image as normative

Examining “fat talk” experimentally in a female dyad: How are women influenced by another woman's body presentation style?

Fat talk, the verbal dissatisfaction that women express about their bodies, was studied in a female dyad whereby participants interacted with a female confederate who either self-derogated, self-accepted, or self-aggrandized. A 2 (participant body esteem: high vs. low) ×3 (confederate style of body image presentation) design was used. Results revealed that participants’ public disclosure of their body image varied according to confederate's style. Consistent with a reciprocity effect, participants disclosed the lowest public body image ratings in the self-derogate condition, with moderate ratings in the self-accept condition, and highest ratings in the self-aggrandize condition. Moreover, participants with low compared to high body esteem stated lower public body image. Participants’ judgments of the confederates’ likeability did not vary as a function of the confederate's body presentational style. Findings support the recursive nature of the social psychology of body image such that personal body image dissatisfaction is partially influenced by fat talk social norms

Social likeability, conformity, and body talk: Does fat talk have a normative rival in female body image conversations?

Fat talk, dialogues among women involving negative body-focused discussions, was studied as a function of conformity and social likeability through the use of four vignettes depicting young women in conversation. Using a 2 (body presentation style of the group: negative or positive) × 2 (body presentation style of the target, Jenny: negative or positive) factorial design, 215 college women (92.1% non-Hispanic Caucasian) read one of four vignettes in a classroom setting and made ratings on a social likeability scale. Participants’ personal ratings of Jenny's likeability were higher when she spoke positively about her body, whereas they expected the other group members in the vignette to like Jenny more when she conformed to the group's body presentation style. This study is the first to support two competing norms for women's body image—the existing norm to fat talk versus a newly documented norm that some women like others who express body acceptance

Oxidative stress and pro-apoptotic conditions in a rodent model of Wilson's disease.

Wilson's disease (WD) is an inherited disorder, characterized by selective copper deposition in liver and brain, chronic hepatitis and extrapyramidal signs. In this study, we investigated changes of biochemical markers of oxidative stress and apoptosis in liver, striatum and cerebral cortex homogenates from Long-Evans Cinnamon (LEC) rats, a mutant strain isolated from Long Evans (LE) rats, in whom spontaneous hepatitis develops shortly after birth. LEC and control (LE) rats at I I and 14 weeks of age were used. We determined tissue levels of glutathione (GSH/GSSG ratio), lipid peroxides, protein-thiols (P-SH), nitric oxide metabolites, activities of caspase-3 and total superoxide-dismutase (SOD), striatal levels of monoamines and serum levels of hepatic amino-transferases. We observed a decrease of protein-thiols, GSH/GSSG ratio and nitrogen species associated to increased lipid peroxidation in the liver and striatum - but not in the cerebral cortex - of LEC rats, accompanied by dramatic increase in serum amino-transferases and decrease of striatal catecholamines. Conversely, SOD and caspase-3 activity increased consistently only in the cortex of LEC rats. Hence, we assume that enhanced oxidative stress may play a central role in the cell degeneration in WD, at the main sites of copper deposition, with discrete pro-apoptotic conditions developing in distal areas

Response of serum proteome in patients undergoing infrarenal aortic aneurysm repair.

BACKGROUND: Postoperative organ dysfunction in conventional surgery for abdominal aortic aneurysm (AAA) is associated with a complex inflammatory reaction, with activation of coagulation and fibrinolysis. A prospective,observational study was performed to define the complex plasma proteomic changes after AAA repair and to identify factor(s) that may affect myocardial function in uncomplicated procedures. METHODS: Ten patients undergoing infrarenal AAA repair were investigated. Eight subjects subjected to major abdominal surgery served as controls. Hemodynamic changes were continuously monitored by using the pressure recording analytical method technique. The time course of plasma proteins was investigated after induction of anesthesia and at different times after surgery (6 h, 12 h, 24 h, 36 h) by using two-dimensional difference gel electrophoresis, matrix-assisted laser desorption/ionization-time of flight mass spectrometry, and Western blot. The effects of plasma on the functional properties of isolated rat ventricular myocytes were also investigated. RESULTS: In AAA patients alone, 18 spots were found to change more than two-fold in expression level, spot identification revealing an increased thrombin generation 6 h after surgery. At the same time cardiac cycle efficiency significantly reduced versus baseline (-0.5 +/- 0.9 vs. 0.18 +/- 0.3 in AAA patients, P < 0.01; 0.4 +/- 0.1 vs. 0.2 +/- 0.3 in control surgery, not significant; P < 0.01 group x time interaction at ANOVA). Plasma obtained 6 h after AAA surgery dose-dependently inhibited contractile function of control rat myocytes (percent shortening fell by 51% with 10% of AAA plasma and was abolished with 20% of AAA plasma, P < 0.001 for both). The inhibitory response was abolished by thrombin antagonism. CONCLUSIONS: These findings show for the first time the possible role of thrombin generation within the complex activation of inflammatory response in causing hemodynamic instability in the early postoperative period after AAA surger

miSolRNA: A tomato micro RNA relational database

Background: The economic importance of Solanaceae plant species is well documented and tomato has become a model for functional genomics studies. In plants, important processes are regulated by microRNAs (miRNA). Description: We describe here a data base integrating genetic map positions of miRNA-targeted genes, their expression profiles and their relations with quantitative fruit metabolic loci and yield associated traits. miSolRNA provides a metadata source to facilitate the construction of hypothesis aimed at defining physiological modes of action of regulatory process underlying the metabolism of the tomato fruit. Conclusions: The MiSolRNA database allows the simple extraction of metadata for the proposal of new hypothesis concerning possible roles of miRNAs in the regulation of tomato fruit metabolism. It permits i) to map miRNAs and their predicted target sites both on expressed (SGN-UNIGENES) and newly annotated sequences (BAC sequences released), ii) to co-locate any predicted miRNA-target interaction with metabolic QTL found in tomato fruits, iii) to retrieve expression data of target genes in tomato fruit along their developmental period and iv) to design further experiments for unresolved questions in complex trait biology based on the use of genetic materials that have been proven to be a useful tools for map-based cloning experiments in Solanaceae plant species
