Cellular expression of low-density lipoprotein receptor-related protein 1 and amyloid beta deposition in human and rat epileptogenic brain.

Decreased capillary expression of low-density lipoprotein receptor-related protein 1 (LRP1) has been linked to increased brain amyloid beta (Aβ) accumulation in Alzheimer's disease (AD). Aβ accumulation has also been observed in (a subset of) temporal lobe epilepsy (TLE) patients, suggesting a potential link between epilepsy and AD. This study examines cellular LRP1 expression in human and rat epileptogenic brain tissue to explore LRP1's role in epilepsy.

Impact of Regulatory Risk Communication on Thrombosis With Thrombocytopenia Syndrome for COVID-19 Adenovirus Vector Vaccines on European Healthcare Professionals.

Purpose: The European Medicines Agency (EMA) issued regulatory actions and communications in 2021 on thrombosis with thrombocytopenia syndrome (TTS) associated with adenovirus vector vaccines Vaxzevria or Jcovden. This study aimed to evaluate the impact of these actions on awareness, knowledge and implementation in practises of healthcare professionals (HCP).

Methods: Web-based cross-sectional surveys were conducted on HCPs engaged in the vaccination, monitoring or counselling about the vaccines.

Circulating microRNAs and isomiRs as biomarkers for the initial insult and epileptogenesis in four experimental epilepsy models: The EPITARGET study.

Objective: Structural epilepsies can manifest months or years after the occurrence of an initial epileptogenic insult, making them amenable for secondary prevention. However, development of preventive treatments has been challenged by a lack of biomarkers for identifying the subset of individuals with the highest risk of epilepsy after the epileptogenic insult.

Methods: Four different rat models of epileptogenesis were investigated to identify differentially expressed circulating microRNA (miRNA) and isomiR profiles as biomarkers for epileptogenesis.

Evaluation of MRI features of neuromas in oncological amputees, and the relation to pain.

Objective: The impact of time on neuroma growth and morphology on pain intensity is unknown. This study aims to assess magnetic resonance imaging (MRI) differences between symptomatic and non-symptomatic neuromas in oncological amputees, and whether time influences MRI-detected neuroma dimensions and their association with pain.

Material And Methods: Oncological patients who underwent traditional extremity amputation were included.

Collagen VI: Role in synaptic transmission and seizure-related excitability.

Collagen VI (Col-VI) is an extracellular matrix protein primarily known for its bridging role in connective tissues that has been suggested to play a neuroprotective role. In the present study we report increased mRNA and protein expression of Col-VI in the hippocampus and cortex at a late stage of epileptogenesis in a post-status epilepticus (SE) model of epilepsy and in brain tissue from patients with epilepsy. We further present a novel finding that exposure of mouse hippocampal slices to Col-VI augments paired-pulse facilitation in Schaffer collateral-CA1 excitatory synapses indicating decreased release probability of glutamate.
