Acute and chronic effects of morphine on cardiovascular system and the baroreflexes sensitivity during severe increase in blood pressure in rats

ARYA Atherosclerosis, 2011
BACKGROUND: This study aimed to determine the role and effects of baroreflexes duringacute increase in blood pressure (BP) after severe and long-term infusion of morphine.METHODS: This experimental study was conducted on male desert rats.

On the adaptive significance of group III/IV muscle afferent feedback for the cardiovascular response during sustained locomotion in humans

The Journal of Physiology, Volume 604, Issue 17, Page 7112-7124, 1 September 2026.
Abstract figure legend Group III/IV leg muscle afferent feedback has previously been recognized as an important determinant of the cardiovascular response to exercise lasting <5 min. Here we demonstrate that the activity of these neurons is crucial in regulating central and peripheral haemodynamic responses during steady state exercise of longer ...

Bedtime tetrahydrocannabinol ingestion reduces morning orthostatic cardiovascular reactivity in adults: An exploratory study

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Acute cannabis use and its primary psychoactive constituent tetrahydrocannabinol (THC) can induce postural dizziness, indicating increased risk of orthostatic instability. However, it is unknown if vulnerabilities persist the morning after bedtime THC consumption.

Effects of converting enzyme inhibition on baroreflex sensitivity in patients with myocardial infarction.

, 1992
BACKGROUND: Baroreflex sensitivity provides useful prognostic information in patients after acute myocardial infarction. However, no data are available about the effects of converting enzyme inhibition on this variable.

Nocturnal peak in cardiac baroreflex effectiveness aligns with nocturnal trough in systolic blood pressure in young healthy adults: Possible circadian effects

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract We tested whether there is a circadian variation in baroreflex function measured as sensitivity and effectiveness, and whether it aligned with circadian variations in systolic blood pressure (BP). Eleven healthy adults (24 ± 2 years; 4 males and 7 females) completed a 30‐h circadian protocol incorporating five recurring, identical, 6‐h cycles ...

Greater muscle mass does not affect peripheral hypercapnic chemosensitivity during exercise in healthy adults

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Peripheral hypercapnic chemosensitivity (PHC) is the ventilatory response to a brief rise in arterial carbon dioxide tension. PHC is known to increase at the onset of exercise, with no further increases with progressive exercise intensity. The mechanisms for this augmentation remain unclear but may involve central command.
