Evaluation of Vasomotor Reactivity by Transcranial Doppler Sonography: Age and Sex Related Differences in Breath Holding Index in Iranian Population

Journal of Research in Medical Sciences, 2005
Background: The assessment of cerebral vasoreactivity can provide information regarding the reserve capacity of cerebral circulation. Reduction of this property has been found in association with situations predisposing one toward cerebrovascular disease.

Efficacy and safety of different vasopressor infusions on feto‐maternal outcomes in normotensive patients undergoing caesarean delivery: a systematic review and network meta‐analysis of randomised controlled trials

Anaesthesia, EarlyView.
Summary Introduction Phenylephrine infusion is widely endorsed by guidelines as the preferred prophylactic drug for spinal hypotension in patients undergoing caesarean delivery; however, clinical practice continues to show marked variability in the selection of vasopressor drugs.

Physiological Basis of Sex Differences in Human Performance and Exercise‐Associated Pathology

Clinical Endocrinology, EarlyView.
ABSTRACT The presence of sex differences in human physical performance is well‐established and shaped by distinct endocrine, anatomical and physiological mechanisms. Despite sustained advances, our understanding of how inherent biological factors drive variations in exercise capacity and related pathologies is still developing.

Vasomotor Regulation of Coronary Microcirculation by Oxidative Stress: Role of Arginase [PDF]

, 2013
Overproduction of reactive oxygen species, i.e., oxidative stress, is associated with the activation of redox signaling pathways linking to inflammatory insults and cardiovascular diseases by impairing endothelial function and consequently blood flow ...

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

Experimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

Discharge of RVLM vasomotor neurons is not increased in anesthetized angiotensin II-salt hypertensive rats [PDF]

, 2013
Neurons of the rostral ventrolateral medulla (RVLM) are critical for generating and regulating sympathetic nerve activity (SNA). Systemic administration of ANG II combined with a high-salt diet induces hypertension that is postulated to involve elevated ...
