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 ...

Cerebral Autoregulation in Sick Infants: Current Insights.
Clinics of Perinatology, 2020 Cerebrovascular autoregulation is the ability to maintain stable cerebral blood flow within a range of cerebral perfusion pressures. When cerebral perfusion pressure is outside the limits of effective autoregulation, the brain is subjected to ...

Autoregulation of Glucose Production
Physiology, 2000 Glucose itself regulates endogenous glucose production independently of changes in glucoregulatory hormones. In addition, acute stimulation of gluconeogenesis does not increase net glucose production. This indicates autoregulation of glucose production. Glucokinase plays a role in this process by allowing hepatic glucose sensing.

Neuroimaging Findings and Risk Factors for Brain Injury in Foetuses Treated for Anaemia
Prenatal Diagnosis, EarlyView.ABSTRACT Objective Characterize neuroimaging findings in foetuses with anaemia and identify associated risk factors. Methods Retrospective cohort study of pregnancies with foetal anaemia (defined as haemoglobin > 2 standard deviations below the gestational age mean) confirmed by foetal blood sampling (FBS) and treated with intrauterine transfusion (IUT)

Acidic C-terminal domains autoregulate the RNA chaperone Hfq
eLife, 2017 The RNA chaperone Hfq is an Sm protein that facilitates base pairing between bacterial small RNAs (sRNAs) and mRNAs involved in stress response and pathogenesis. Hfq possesses an intrinsically disordered C-terminal domain (CTD) that may tune the function

Predictors of Brain Infarction in Pediatric Patients During Extracorporeal Membrane Oxygenation
Artificial Organs, EarlyView.In 179 pediatric ECMO patients, brain infarction (BI) occurred in 28% and was linked to markedly higher 30‐day mortality. VA ECMO mode (vs. VV) and higher pre‐ECMO arterial lactate independently predicted BI, supporting standardized neuro‐monitoring and liberal early brain CT, especially for children on VA ECMO.
