Pregnancy impairs baroreflex gain, but the mechanism is incompletely understood. To test the hypothesis that reductions in brain insulin contribute, we determined whether pregnant rats exhibit lower cerebrospinal fluid (CSF) insulin concentrations and whether intracerebroventricular infusion of insulin normalizes gain of baroreflex control of heart rate in conscious pregnant rats. CSF insulin w...

A group of 16 male youth with spastic diplegy of lower extremities were examined. Their mean age was 18.5 years, body height 166.5 ± 6,6 cm, and body mass 57.4 ± 7,7 kg. They were subjected to a graded cycle ergometer arm exercise until exhaustion. The following indices of the circulatory and respiratory systems at maximum intensity and at the ventilatory threshold (VT) were recorded: percentag...

objective: the objective of this study was to investigate the effect of four weeks aerobic training on serum glucagon-like peptide-1 (glp-1) in women with type 2 diabetes mellitus (t2dm). materials and methods: twenty t2dm patients (33-53 years) were randomly assigned into control (n=10) and experimental (n=10) groups. the main intervention included running on treadmill, reaching 55 to 80% of t...

This study investigated the effects of wave conditions on performance and the physiological responses of surfers. After institutional ethical approval 39 recreational surfers participated in 60 surfing sessions where performance and physiological response were measured using global positioning system (GPS) heart rate monitors. Using GPS, the percentage time spent in surfing activity categories ...

The organization within the descending sympathetic pathways on the surface of the dorsolateral funiculus of the spinal cord was investigated in anesthetized dogs. Changes in heart rate and carotid, renal, and femoral resistances were calculated during electrical stimulation of the descending spinal sympathetic pathways; the location within the pathway of the maximum change in each of these para...
