Experimental Physiology, EarlyView.Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

Experimental Physiology, EarlyView.Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Experimental Physiology, EarlyView.Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.

Experimental Physiology, EarlyView.Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Iron-Dependent Transcription of the Regulatory Gene ros of Agrobacterium radiobacter
Molecular Plant-Microbe Interactions, 1997 Transcription of the regulatory gene ros of Agrobacterium radiobacter requires growth in the presence of Fe although this regulation was not mediated by ros itself.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Experimental Physiology, EarlyView.Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Static autoregulation in humans [PDF]
Journal of Cerebral Blood Flow & MetabolismA recent publication in JCBFM, “Static autoregulation in humans” gives rise to critical comments. Autoregulation of cerebral blood flow implies that flow is rather constant within a certain blood pressure (BP) range with a lower and an upper pressure limit.
