A Hippocampal-Entorhinal Cortex Neuronal Network for Dynamical Mechanisms of Epileptic Seizure

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Temporal lobe epilepsy (TLE) is thought to be associated with neuronal hyperexcitability in the hippocampal-entorhinal cortical (EC) circuit. Due to the complexity of the hippocampal-EC network connections, the biophysical mechanisms of the different ...

Entorhinal theta-frequency input to the dentate gyrus trisynaptically evokes hippocampal CA1 LTP

Frontiers in Neural Circuits, 2012
There exists substantial evidence that some forms of explicit learning in mammals require long-term potentiation (LTP) at hippocampal CA3-CA1 synapses. While CA1 LTP has been well characterized at the monosynaptic level, it still remains unclear how the ...

Circuit Model Analysis of Switchable Perfect Absorption/Reflection in an Active Frequency Selective Surface

IEEE Access, 2019
This paper presents a switchable perfect absorber/reflector in S band using a PIN diode integrated active frequency selective surface (AFSS). It is numerically demonstrated that the AFSS shows over 99% absorptivity at 3.5 GHz when the diode is forward ...

Papez circuit remodeling in type 2 diabetes: Enlarged choroid plexus volume partially mediates functional impairments linked to insulin resistance

NeuroImage
Aim: Type 2 diabetes mellitus (T2DM) is a metabolic disorder associated with cognitive decline. This study investigated the interplay between altered effective connectivity (EC) in the Papez circuit, regional atrophy, and choroid plexus volume (CPV) in ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
