11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD-1) catalyses the interconversion of active cortisol and corticosterone with inert cortisone and 11-dehydrocorticosterone, thus regulating glucocorticoid access to intracellular receptors. In rats, chronic glucocorticoid excess or stress increases 11beta-HSD-1 in the hippocampus, producing suggestions that it may attenuate the deleterious effects of chronic glucocorticoid excess. However, 11beta-HSD-1 predominantly catalyses 11beta-reduction in the intact liver and hippocampal cells, thus regenerating active glucocorticoids from inert substrate. We studied 11beta-HSD activity in the tissues of male tree shrews following 28 days of sustained psychosocial stress or exogenous administration of cortisol. In the hippocampus, chronic psychosocial stress attenuated 11-HSD-1 activity (69 +/- 9% of control), whereas cortisol alone had no effect. In the liver, both chronic stress and cortisol administration decreased 11beta-HSD-1 activity (47 +/- 11% and 49 +/- 4% fall, resp.). Attenuation of 11beta-HSD-1 within tissues may reflect a homeostatic mechanism designed to minimise the adverse effects of prolonged stress and/or glucocorticoid excess. 相似文献

In this article, the authors report a secondary analysis on a cross-cultural dataset on gender differences in 6 emotions, collected in 37 countries all over the world. The aim was to test the universality of the gender-specific pattern found in studies with Western respondents, namely that men report more powerful emotions (e.g., anger), whereas women report more powerless emotions (e.g., sadness, fear). The authors expected the strength of these gender differences to depend on women's status and roles in their respective countries, as operationalized by the Gender Empowerment Measure (GEM; United Nations Development Programme Human Development Report 2002). Overall, the gender-specific pattern of women reporting to experience and express more powerless emotions and men more powerful emotions was replicated, and only some interactions with the GEM were found. 相似文献

Two studies examined anger and shame, and their associated appraisals and behavioral intentions, in response to harm to an in-group's social-image. In Study 1, 37 British Muslims (18 men, 19 women) reported incidents in which they were devalued as Muslims. In Study 2, 108 British Muslims (57 females, 50 males, 1 undisclosed) were presented with objective evidence of their in-group's devaluation: the controversial cartoons about Prophet Muhammad The appraisal of harm to social-image predicted anger and shame (Studies 1 and 2), whereas the appraisal of offense only predicted anger (Study 2). Anger was a more empowering response than shame, as anger predicted willingness for public confrontation (Studies 1 & 2), institutional punishment (Study 2), and written disapproval (Study 2). In contrast, shame only predicted written disapproval (Study 2). Furthermore, independent of individual differences in identification as Muslim, a mediation model showed that individual differences in honor orientation predicted anger and shame via the appraisals (Study 2). Implications for theory and research are discussed. 相似文献

We studied the relationship between perceived social image and life satisfaction in four different cultural groups. One-hundred nine Indian (63 females, 46 males), 67 Pakistani/Bangladeshi (36 females, 31 males), 76 White British (43 females, 33 males), and 94 European Americans (43 females, 48 males) completed measures on the cultural importance of social image, positive and negative emotions, academic achievement, and perceived social image. Indian and Pakistani/Bangladeshi participants valued social image more than White British and European-American participants. Consistent with this value difference, a positive perceived social image predicted life satisfaction among Indian and Pakistani/Bangladeshi participants only. For these participants, perceived social image predicted life satisfaction above and beyond the effects of emotions and academic achievement. Academic achievement only predicted life satisfaction among White British and European Americans. Emotions were significant predictors of life satisfaction for all participants. 相似文献

The three major hereditary cancer syndromes in Latinos (Hereditary Breast and Ovarian Cancer, Familial Adenomatous Polyposis and Lynch Syndrome) have been shown to exhibit geographic disparities by country of origin suggesting admixture-based disparities. A solid infrastructure of clinical genetics geared towards diagnosis and prevention could aid in reducing the mortality of these cancer syndromes in Latinos. Currently, clinical cancer genetic services in Latin America are scarce. Moreover, limited studies have investigated the mutational spectrum of these cancer syndromes in Latinos resulting in gaps in personalized medicine affecting diagnosis, treatment and prevention. The following commentary discusses available genotype and clinical information on hereditary cancer in Latinos and highlights the limited access for cancer genetic services in Latin America including barriers to genetic testing and alternatives for providing better access to genetic services. In this review, we discuss the status of clinical genetic cancer services for both US Latinos and those Latinos living in Latin America. 相似文献

I fear your envy, I rejoice in your coveting: on the ambivalent experience of being envied by others
Rodriguez Mosquera PM Parrott WG Hurtado de Mendoza A 《Journal of personality and social psychology》2010,99(5):842-854
We present 2 studies on being envied. Study 1 used an emotional narrative methodology. We asked 44 Spanish (23 women, 21 men) and 48 European American (36 women, 12 men) participants to tell us about a recent experience in which others envied them. We classified the antecedents, relationship context, markers of envy, coping strategies, and positive and negative implications of being envied. In Study 2, 174 Spanish (88 women, 86 men) and 205 European American (106 women, 99 men) participants responded to a situation in which they had something someone else wanted. We manipulated the object of desire (academic achievement or having "a better life"). We measured individual differences in orientation to achievement (i.e., vertical individualism), cooperation and interpersonal harmony (i.e., horizontal collectivism), a zero-sum view of success, beliefs that success begets hostile coveting, fear of success, and dispositional envy. We also measured participants' appraisals, positive and negative emotions, and coping strategies. The findings from both studies indicate that being envied has both positive (e.g., increased self-confidence) and negative consequences (e.g., fear of ill will from others). Being envied had more positive and more negative psychological and relational consequences among those participants who were achievement oriented (European Americans) than among participants who were oriented to cooperation and interpersonal harmony (Spanish). 相似文献

Insults elicit intense emotion. This study tests the hypothesis that one's social image, which is especially salient in honour cultures, influences the way in which one reacts to an insult. Seventy-seven honour-oriented and 72 non-honour oriented participants answered questions about a recent insult episode. Participants experienced both anger and shame in reaction to the insult. However, these emotions resulted in different behaviours. Anger led to verbal attack (i.e., criticising, insulting in return) among all participants. This relationship was explained by participants’ motivation to punish the wrongdoer. Shame, on the other hand, was moderated by honour. Shame led to verbal disapproval of the wrongdoers behaviour, but only among the honour-oriented participants. This relationship was explained by these participants’ motivation to protect their social image. By contrast, shame led to withdrawal among non-honour-oriented participants. 相似文献

The events of 9/11 marked an increase in prejudice, discrimination, and other forms of unfair treatment toward Muslim Americans. We present a study that examined the emotions of Muslim Americans in the days preceding the ten-year 9/11 anniversary. We measured the antecedents (concerns) and consequences (coping) of sadness, fear, and anger. The 9/11 anniversary precipitated intense concerns with loss and discrimination, and intense feelings of sadness, fear, and anger. We measured three coping responses: rumination, avoidance of public places, and religious coping. Participants engaged in all three coping responses, with seeking solace in one's religion being the most frequent response. Moreover, emotions mediated the relationship between concerns and coping responses. Sadness accounted for the association between concern with loss and rumination. Fear explained the association between concern with discrimination and avoidance. Anger accounted for the association between concern with discrimination and religious coping. 相似文献
