Studies of emotion have provided occasional support for physiological differentiation of affective states; however, the evidence has been inconsistent. The aims of the present study were to investigate cardiovascular changes associated with relived experiences of happiness, sadness, anger, fear, and disgust and to examine the utility of methods designed to(More)
Prolactin administration reportedly increases blood pressure in rats and rabbits. To study the effects of prolactin deficiency on blood pressure, rats were given saline, normal rabbit serum, or rabbit antiserum to rat prolactin on postnatal days 2 to 5. Both males and females given antiserum had significantly lower blood pressure at 14 weeks than rats given(More)
Hemodynamic responses to an anger interview and cognitive and physical stressors were compared, and the stability of associated hemodynamic reactions examined. Participants experienced control, handgrip, counting, and mental arithmetic tests and an anger interview on two occasions. Systolic and diastolic blood pressure, heart rate, stroke volume, and(More)
Organic single crystals provide an ideal model for studying the factors that influence chemical processes in structured media. Reaction trajectories are well defined and reveal the influence of spontaneous mechanical stresses equivalent to tens of thousands of atmospheres. Analysis of molecular and crystal structures helps to explain both local mechanical(More)
The influence of oxidative stress, diaphragm fatigue, and inspiratory muscle training (IMT) on the cytokine response to maximum sustainable voluntary ventilation (MSVV) is unknown. Twelve healthy males were divided equally into an IMT or placebo (PLA) group, and before and after a 6-wk intervention they undertook, on separate days, 1 h of (1) passive rest(More)
We examined differing predictions of how emotional expressions and blood pressure are related. Spontaneous positive and negative facial expressions, resting systolic blood pressure (SBP), and reactive SBP were each measured for 148 male and female undergraduates. The discharge theory of emotions proposes that few expressions will predict higher baseline(More)
