Cardiomyopathic hamsters (CMH) develop heart disease early in life which leads to congestive heart failure and death as these hamsters age. We have previously shown that living in constant light or other non-24-h light-dark (LD) cycles can increase l

A group of old (mean age 73 years) and young (mean age 19.8 years) human subjects received concomitant eyeblink and heart rate classical conditioning, in which a 1000 Hz tone was the conditioning stimulus and a corneal airpuff was the unconditioned s

For 5 days, rats were exposed to shocks that were signalled by a light 0, 33, 66, or 100% of the time. Basal hormone levels and responses to a light-shock pair were measured daily. Greater predictability was associated with higher basal plasma cortic

To evaluate our clinical impression that patients with the chronic fatigue syndrome (CFS) did not walk normally, we assessed gait kinematics at slow walking speeds (i.e., 0.45, 0.89 and 1.34 m/sec) and 30 m run time speeds on CFS patients and on a co

Patients with chronic fatigue syndrome (CFS) often complain of an inability to maintain activity levels and a variety of autonomic-like symptoms that make everyday activiry intolerable at times. The purpose of the study was to determine if there were

Our previous work has shown that constant light can prolong the life of hamsters with heart disease. Although we have seen this result several times, constant light was not protective in our most recent experiment. We undertook this study because we

The chronic stress state has previously been defined as persistent visceral arousal coupled with behavioral abnormalities. To determine the number of stressor exposures necessary to induce a chronic stress state, male rats were given 2 hours of inesc

This study examined the effects of aging and chronic congestive heart failure on plasma corticosterone and cortisol levels in hamsters. It also assessed the effects of aging and heart failure on glucocorticoid responses to acute and chronic stress. A

The respiratory influence on heart-rate variability is investigated. The experiment took ECG and respiratory signals from ten normal healthy subjects. A matrix of tests was conducted in different postures (sitting and standing) and with different bre
