Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

Experimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

Effect of prolonged voluntary wheel running on oxidative stress and defence mechanisms in cortex and hippocampus of healthy female rats

Experimental Physiology, EarlyView.
Abstract Physical exercise promotes brain health and cognitive function possibly through mechanisms that include strengthened resistance to oxidative stress. However, limited research has explored the cumulative effects of regular voluntary exercise on both oxidative stress and defence mechanisms in hippocampus and cortex, two regions essential for ...

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 ...

Astrocytes: Orchestrators of brain gas exchange and oxygen homeostasis

The Journal of Physiology, EarlyView.
Abstract figure legend Oxygen and carbon dioxide enter the body via breathing; in the brain astrocytes play a key role balancing oxygen delivery with carbon dioxide removal. Abstract If we consider neurons like muscles during exercise, the demand for oxygen (O2) and carbon dioxide (CO2) elimination is constantly changing.

Targeting ecto‐5′‐nucleotidase (CD73) and cAMP alleviates carotid body hyperactivity and reduces blood pressure in chronically hypoxic rats

The Journal of Physiology, EarlyView.
Abstract figure legend CD73 promotes carotid body hyperactivity in chronically hypoxic animals. Exposure to chronic hypoxia (CH) (FiO2 of 12% for 10 days) increases the proportion of CD73+TH+ cells in the carotid body and induces basal chemoafferent hyperactivity.
