Impaired cerebral autoregulation is associated with brain dysfunction in patients with sepsis
Critical Care, 2018 BackgroundSepsis-associated brain dysfunction (SABD) is associated with high morbidity and mortality. The pathophysiology of SABD is multifactorial.

A method to assess Granger causality, isolation and autonomy in the time and frequency domains: theory and application to cerebrovascular variability [PDF]
arXiv, 2023 Concepts of Granger causality (GC) and Granger autonomy (GA) are central to assess the dynamics of coupled physiologic processes. While causality measures have been already proposed and applied in time and frequency domains, measures quantifying self-dependencies are still limited to the time-domain formulation and lack of a clear spectral ...

Under-dominance constrains the evolution of negative autoregulation in diploids [PDF]
PLoS Comput Biol, 2013, 9(3): e1002992, 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. Theoretical work and empirical investigation in Escherichia coli have shown that negative autoregulation confers both rapid response times and reduced ...

The influence of carotid disease on cerebral vascular autoregulation and cerebral vascular reactivity to hypercapnia [PDF]
, 1995 Cerebral vascular reactivity to hypercapnia, assessed using transcranial Doppler ultrasonography of middle cerebral artery blood flow velocity, is used to assess the extent of cerebral blood flow reserve.

Neurovascular coupling and cerebral autoregulation in atrial fibrillation
Journal of Cerebral Blood Flow and Metabolism, 2019 The risk of cognitive decline and stroke is increased by atrial fibrillation (AF). We sought to determine whether neurovascular coupling and cerebral autoregulation are blunted in people with AF in comparison with age-matched, patients with hypertension ...

Inference on autoregulation in gene expression [PDF]
arXiv, 2022 Some genes can promote or repress their own expressions, which is called autoregulation. Although gene regulation is a central topic in biology, autoregulation is much less studied. In general, it is extremely difficult to determine the existence of autoregulation with direct biochemical approaches.

METHOD FOR DETERMINING THE UPPER LIMIT OF CEREBRAL AUTOREGULATION IN RATS
Фармация и фармакология (Пятигорск), 2018 The main objective of the phenomenon of cerebral autoregulation is to maintain a constant cerebral blood flow rate with changes in systemic arterial pressure in the range of 50 mmH up to 150 Mmhg.

Towards Assistive Diagnoses in m-Health: A Gray-box Neural Model for Cerebral Autoregulation Index [PDF]
arXiv, 2020 The cerebral autoregulation system (CAS), is a mechanism which aims to regulate pressure variations occurring in the cerebral circulatory system. At present, there only exist invasive methods and, in turn, they are not used to prevent cerebrovascular accidents.

Using Fano factors to determine certain types of gene autoregulation [PDF]
arXiv, 2023 The expression of one gene might be regulated by its corresponding protein, which is called autoregulation. Although gene regulation is a central topic in biology, autoregulation is much less studied. In general, it is extremely difficult to determine the existence of autoregulation with direct biochemical approaches.
