Does Exposure to Stressors Predict Changes in Physiological Dysregulation?

Do chronic stressors lead to physiological dysregulation? Testing the theory of allostatic load.

OBJECTIVES To explore three questions: 1) Do chronic stressors predict physiological dysregulation? 2) Is that relationship moderated by characteristics of the individual and his or her social environment? and 3) Do perceived levels of stress mediate the relationship between stressors and dysregulation? METHODS Data come from a nationally representative, longitudinal study of older Taiwanese ...

Does Exposure to Music Videos Predict Adolescents' Sexual Attitudes?

This study investigates whether exposure to music videos predicts adolescents' sexual attitudes when controlled for relevant characteristics of individuals and their social environment. Sexual attitudes are related to their music video use (i.e. exposure to music videos, peer group talk about music videos, and perceived realism of these videos), personal factors and the sexual norms they percei...

Changes in biochemical and physiological responses of common carp, Cyprinus carpio L. after long-term exposure to Pb (II)

In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were  investigated using  several  biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepat...

Modeling Multisystem Physiological Dysregulation.

OBJECTIVES The purposes of this study were to compare the relative fit of two alternative factor models of allostatic load (AL) and physiological systems, and to test factor invariance across age and sex. METHODS Data were from the Midlife in the United States II Biomarker Project, a large (n = 1255) multisite study of adults aged 34 to 84 years (56.8% women). Specifically, 23 biomarkers were...
