Critical Care Medicine, 2020 OBJECTIVES Monitoring cerebral autoregulation may help identify the lower limit of autoregulation in individual patients. Mean arterial blood pressure below lower limit of autoregulation appears to be a risk factor for postoperative acute kidney injury ...

Nitrogen modulation of legume root architecture signaling pathways involves phytohormones and small regulatory molecules [PDF]
, 2015 Nitrogen, particularly nitrate is an important yield determinant for crops. However, current agricultural practice with excessive fertilizer usage has detrimental effects on the environment.

A Stochastic Analysis of Autoregulation of Gene Expression
, 2016 This paper analyzes, in the context of a prokaryotic cell, the stochastic variability of the number of proteins when there is a control of gene expression by an autoregulation scheme.

Dynamic cerebral autoregulation is attenuated in young fit women
Physiological Reports, 2019 Young women exhibit higher prevalence of orthostatic hypotension with presyncopal symptoms compared to men. These symptoms could be influenced by an attenuated ability of the cerebrovasculature to respond to rapid blood pressure (BP) changes [dynamic ...

Frontiers in Medicine, 2021 Background: Ischemic and hyperemic injury have emerged as biologic mechanisms that contribute to cognitive impairment in critically ill patients. Spontaneous deviations in cerebral blood flow (CBF) beyond ischemic and hyperemic thresholds may represent ...

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]
, 2017 Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

The effect of feedback on the fidelity of information transmission of time-varying signals
, 2010 Living cells are continually exposed to environmental signals that vary in time. These signals are detected and processed by biochemical networks, which are often highly stochastic.

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT It is evident that Turner syndrome (TS) impacts almost all developmental stages of the fetal heart with congenital heart disease (CHD) being seen in 23%–50% of individuals. Although the spectrum of CHDs in TS is well‐established, with left‐sided lesions predominating, the influence of specific karyotypes on the prevalence and types of CHDs ...

Adaptive feedback analysis and control of programmable stimuli for assessment of cerebrovascular function [PDF]
, 2013 The assessment of cerebrovascular regulatory mechanisms often requires flexibly controlled and precisely timed changes in arterial blood pressure (ABP) and/or inspired CO2.
