Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Role of S1P‐ and Rho‐kinase signalling in age‐related myogenic tone deficiency in murine resistance arteries

Experimental Physiology, EarlyView.
Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...

Improved cerebral autoregulation index

, 2009
Objective: The linear correlation coefficient of PtiO2 / CPP or ICP / CPP serves as a quantitative index for the status of cerebral autoregulation, yet it is merely a surrogate marker for the true hemodynamic situation best characterized by invasive CBF measurement. Furthermore, the delay [for full text, please go to the a.m. URL]

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

The angiotensin II type I receptor contributes to impaired cerebral blood flow autoregulation caused by placental ischemia in pregnant rats

Biology of Sex Differences, 2019
Background Placental ischemia and hypertension, characteristic features of preeclampsia, are associated with impaired cerebral blood flow (CBF) autoregulation and cerebral edema.

Effect of a single exercise bout on fasting cerebral blood flow and brain insulin sensitivity in middle‐aged to older adults

Experimental Physiology, EarlyView.
Abstract Reductions in brain insulin sensitivity and cerebral blood flow (CBF) have emerged as potential factors contributing to Alzheimer's disease and related dementia. However, no work has tested whether a single bout of exercise can raise brain insulin sensitivity in at‐risk adults. The aim of the study was to test whether a single bout of exercise

Carotid sinus baroafferent signals contribute to cerebral blood flow regulation during acute hypotension in young males: A randomized crossover study

Physiological Reports
Cerebral autoregulation is an important factor in prevention of cerebral ischemic events. We tested a traditional but unproven hypothesis that carotid sinus baroafferent signals contribute to dynamic cerebral autoregulation.
