Renal autoregulation in health and disease.

Physiological Reviews, 2015
Intrarenal autoregulatory mechanisms maintain renal blood flow (RBF) and glomerular filtration rate (GFR) independent of renal perfusion pressure (RPP) over a defined range (80-180 mmHg).

The role of child language ability and parental mentalization in early child dysregulation

Infant Mental Health Journal: Infancy and Early Childhood, EarlyView.
Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...

Shifting concepts of autoregulation: Commentary to ‘Static autoregulation in humans' [PDF]

Journal of Cerebral Blood Flow & Metabolism
Advances in imaging techniques have transformed our understanding of cerebral autoregulation. Older imaging techniques provided measurements of cerebral blood flow (CBF) that reflected the average CBF over a window of 10–20 minutes. A key finding, dating back to 1959, was that CBF remained more or less stable over a remarkably wide range of changes in

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 ...

Association of In Vivo Kidney Stiffness Measured by Multifrequency MR Elastography and Long‐Term Renal Function in Transplant Recipients and Living Donors

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Kidney transplant (KTx) function assessment is important in treatment planning, while conventional MRI markers lack sensitivity for KTx function. Mechanical kidney properties may serve as MRI markers for renal allograft function. Hypothesis To determine if multifrequency MR elastography (MRE) is associated with KTx function.

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 ...

Assessing Executive Function in Pediatric Sleep‐Disordered Breathing Using Functional Neuroimaging

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Sleep‐disordered breathing (SDB) affects 10% of children and is associated with poor academic performance related to inattention and executive dysfunction. Yet, the underlying neural mechanisms remain poorly understood, especially in elementary school‐aged children who cannot sit still for functional magnetic resonance imaging.

Robustness and modular design of the Drosophila segment polarity network [PDF]

, 2006
Biomolecular networks have to perform their functions robustly. A robust function may have preferences in the topological structures of the underlying network.

Characterizing fetoplacental response to acute maternal hyperoxygenation in suspected coarctation of aorta using fetal cardiac MRI

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective To characterize the fetoplacental response to acute maternal hyperoxygenation (AMH) in fetuses with suspected coarctation of the aorta (CoA) using fetal cardiac magnetic resonance imaging (MRI). Methods Pregnant women carrying a fetus with suspected CoA were recruited prospectively from a tertiary fetal cardiology center as part of ...
