Measures of tonic and phasic activity of the locus coeruleus—norepinephrine system in children with autism spectrum disorder: An event‐related potential and pupillometry study

open access: yesAutism Research, Volume 15, Issue 12, Page 2250-2264, December 2022., 2022
Abstract A growing body of research suggests that locus coeruleus‐norepinephrine (LC‐NE) system may function differently in individuals with autism spectrum disorder (ASD). Understanding the dynamics of both tonic (resting pupil diameter) and phasic (pupil dilation response [PDR] and event‐related potential [ERP]) indices may provide meaningful ...

Vasopressin versus norepinephrine in septic shock: a propensity score matched efficiency retrospective cohort study in the VASST coordinating center hospital

open access: yesJournal of Intensive Care, 2018
Purpose It is not clear whether vasopressin versus norepinephrine changed mortality in clinical practice in the Vasopressin and Septic Shock Trial (VASST) coordinating center hospital after VASST was published.

TYRAMINE REVEALS FAILING α2-ADRENOCEPTOR CONTROL OF CATECHOLAMINE RELEASE AND TOTAL PERIPEHRAL VASCULAR RESISTANCE IN HYPERTENSIVE RATS

open access: yesFrontiers in Neurology, 2013
α2-adrenoceptor-activation lowers central sympathetic output, peripheral, vesicular norepinephrine release, epinephrine secretion and modulates vascular tension.

Potential and Realized Impact of Astroglia Ca2 + Dynamics on Circuit Function and Behavior

open access: yesFrontiers in Cellular Neuroscience, 2021
Astroglia display a wide range of spontaneous and behavioral state-dependent Ca2+ dynamics. During heightened vigilance, noradrenergic signaling leads to quasi-synchronous Ca2+ elevations encompassing soma and processes across the brain-wide astroglia ...

Structure Modeling of the Norepinephrine Transporter [PDF]

open access: yesBiomolecules, 2020
The norepinephrine transporter (NET) is one of the monoamine transporters. Its X-ray crystal structure has not been obtained yet. Inhibitors of human NET (hNET) play a major role in the treatment of many central and peripheral nervous system diseases.

Human norepinephrine metabolism [PDF]

open access: yesJournal of Clinical Investigation, 1971
It has become increasingly apparent that evaluation of human norepinephrine metabolism simply by assay of catecholamines in urine is inadequate for differentiation of many physiological or pathological states. In an attempt to examine norepinepherine metabolism in the human subject, tritium-labeled d,l-norepinephrine was administered to 11 normal ...

Norepinephrine enhances the LPS-induced expression of COX-2 and secretion of PGE2 in primary rat microglia

open access: yesJournal of Neuroinflammation, 2010
Background Recent studies suggest an important role for neurotransmitters as modulators of inflammation. Neuroinflammatory mediators such as cytokines and molecules of the arachidonic acid pathway are generated and released by microglia.

A Comparative Study to Evaluate the Effect of Norepinephrine and Phenylephrine in the Treatment of Post Spinal Hypotension for Caesarean Section

open access: yesArchives of Anesthesia and Critical Care, 2022
Background: Maternal hypotension due to spinal anaesthesia in caesarean section is commonly seen. Alongwith fluid loading, phenylephrine is used to manage the hypotension. However, this drug is associated with cardiovascular side effects.

Plasma norepinephrine and mortality [PDF]

open access: yesClinical Cardiology, 1995
Plasma norepinephrine levels, which reflect sympathetic nervous system activity, are almost universally elevated in patients with left ventricular dysfunction. This elevation occurs in patients with overt, symptomatic heart failure (HF) and in patients with asymptomatic left ventricular dysfunction.
