Autoregulation of Neurogenesis by GDF11 [PDF]

Neuron, 2003
In the olfactory epithelium (OE), generation of new neurons by neuronal progenitors is inhibited by a signal from neurons themselves. Here we provide evidence that this feedback inhibitory signal is growth and differentiation factor 11 (GDF11). Both GDF11 and its receptors are expressed by OE neurons and progenitors, and GDF11 inhibits OE neurogenesis ...

Cerebral autoregulation monitoring in neonates and infants after cardiac surgery with cardiopulmonary bypass - comparison of single ventricle and biventricular physiology

Frontiers in Pediatrics
IntroductionCardiopulmonary bypass surgery can lead to impaired cerebral autoregulation with the risk for ischemia, hemorrhage and delirium. In particular, infants with single ventricle physiology have altered hemodynamics with persistent veno-arterial ...

Sport-Related Concussion Alters Indices of Dynamic Cerebral Autoregulation

Frontiers in Neurology, 2018
Sport-related concussion is known to affect a variety of brain functions. However, the impact of this brain injury on cerebral autoregulation (CA) is poorly understood. Thus, the goal of the current study was to determine the acute and cumulative effects

Autoregulation of Hepatic Circulation

Japanese 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.

Homeometric Autoregulation in the Heart [PDF]

Circulation Research, 1960
The effect of increasing the activity of the ventricle on its contractility was investigated. Several beats after the ventricle increases the amount of tension it develops per unit of time, it exhibits an increased contractility as shown by the increase in work and the more rapid development of pressure from a given end-diastolic pressure or fiber ...

N‐Terminal Pro Brain, N‐Terminal Pro Atrial Natriuretic Peptides, and Dynamic Cerebral Autoregulation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Elevated natriuretic peptides (NP) are associated with adverse cerebrovascular conditions including stroke, cerebral small vessel disease, and dementia. However, the mechanisms underlying these associations remain unclear.

Modulation of firing and synaptic transmission of serotonergic neurons by intrinsic G protein-coupled receptors and ion channels

Frontiers in Integrative Neuroscience, 2013
Serotonergic neurons project to virtually all regions of the CNS and are consequently involved in many critical physiological functions such as mood, sexual behavior, feeding, sleep/wake cycle, memory, cognition, blood pressure regulation, breathing and ...
