Cortical transit time: understanding utility and pitfalls in children with pelviureteric junction obstruction

Journal of Pediatric Urology, 2020
Delayed cortical transit time (CTT) has been recently studied and proposed as a parameter that can predict the need for surgery in children with pelviureteric junction obstruction (PUJO).The aim of this study was to study the change in CTT, after surgery, in children with PUJO and to correlate CTT with intrapelvic pressure of the kidney.A prospective ...

Increased cortical capillary transit time heterogeneity in Alzheimer's disease: a DSC-MRI perfusion study [PDF]

Neurobiology of Aging, 2017
Alzheimer's disease (AD) is characterized by the accumulation of hyperphosphorylated tau and neurotoxic Aβ in the brain parenchyma. Hypoxia caused by microvascular changes and disturbed capillary flows could stimulate this build-up of AD-specific proteins in the brain.

Multiple Stochastic Resonances and Oscillation Transitions in Cortical Networks With Time Delay

IEEE Transactions on Fuzzy Systems, 2020
Stochasticity and oscillation play a vital role in neural signal processing. Time delay, which is inevitable in biological neural systems, has significant effect on the dynamics of neuronal networks. This paper provides an analysis of how time delay affects stochastic resonance and firing rate oscillation of cortical neuronal networks.

Cortical transit time as a predictive marker of the need for surgery in children with pelvi-ureteric junction stenosis: Preliminary study

Journal of Pediatric Urology, 2013
Postnatal management of prenatally detected hydronephrosis remains controversial. It has been suggested that cortical transit time (CTT) could successfully predict deterioration in children with pelvi-ureteric junction (PUJ) obstruction. We decided to conduct a retrospective study in our hydronephrosis population to evaluate whether initial CTT was ...
