Job strain, ethnicity, and sympathetic nervous system activity.
Several studies have demonstrated that blacks have heightened pressor sensitivity in response to the alpha-agonist, phenylephrine.

متن کاملNervous System Ghrelin Modulates Sympathetic Nervous System Activity and Stress Response in Lean and Overweight Men
Ghrelin is a growth hormone–releasing peptide secreted by the stomach with potent effects on appetite. Experimental and clinical studies indicate that ghrelin also influences cardiovascular regulation and metabolic function and mediates behavioral responses to stress. We investigated the effects of ghrelin on blood pressure (BP), sympathetic nervous system activity, and mental stress responses ...

متن کاملRelation of obesity and diet to sympathetic nervous system activity.
The hypothesis that dietary intake and obesity stimulate the sympathetic nervous system was investigated in a cross-sectional study of 572 men aged 43-85 years from the Normative Aging Study. Habitus was represented by body mass index, as a measure of overall adiposity, and by the ratio of abdomen-to-hip circumference (abdomen/hip ratio), as a measure of centripetal fat distribution. Sympatheti...
متن کاملMeasuring and quantifying skin sympathetic nervous system activity in humans.
Development of the technique of microneurography has substantially increased our understanding of the function of the sympathetic nervous system (SNS) in health and in disease. The ability to directly record signals from peripheral autonomic nerves in conscious humans allows for qualitative and quantitative characterization of SNS responses to specific stimuli and over time. Furthermore, distin...
