Under-dominance constrains the evolution of negative autoregulation in diploids [PDF]

open access: yes, 2012
Regulatory networks have evolved to allow gene expression to rapidly track changes in the environment as well as to buffer perturbations and maintain cellular homeostasis in the absence of change.

Cerebral blood flow regulation is not acutely altered after a typical number of headers in women footballers

open access: yesFrontiers in Neurology, 2022
BackgroundThe repeated act of heading has been implicated in the link between football participation and risk of neurodegenerative disease, and acutely alters cerebrovascular outcomes in men.

Effect of Targeting Mean Arterial Pressure During Cardiopulmonary Bypass by Monitoring Cerebral Autoregulation on Postsurgical Delirium Among Older Patients: A Nested Randomized Clinical Trial.

open access: yesJAMA Surgery, 2019
Importance Delirium occurs in up to 52% of patients after cardiac surgery and may result from changes in cerebral perfusion. Using intraoperative cerebral autoregulation monitoring to individualize and optimize cerebral perfusion may be a useful strategy

Autoregulation of Hepatic Circulation

open access: yesJapanese Heart Journal, 1966
(1) The pressure-flow relations in both the hepatic artery and the portal vein system were investigated in a total of 13 dog livers, perfused with the homologous blood by a pump oxygenator. In addition, the interaction between the hepatic artery and the portal vein system was also studied.
