Diffusion Tractography Biomarker for Epilepsy Severity in Children With Drug‐Resistant Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To develop a novel deep‐learning model of clinical DWI tractography that can accurately predict the general assessment of epilepsy severity (GASE) in pediatric drug‐resistant epilepsy (DRE) and test if it can screen diverse neurocognitive impairments identified through neuropsychological assessments.

A condition on the potential for the existence of doubly periodic solutions of a semi-linear fourth-order partial differential equation

open access: yesElectronic Journal of Differential Equations, 2000
We study the existence of solutions to the fourth order semi-linear equation $Delta ^2u=g(u)+h(x)$. We show that there is a positive constant $C_*$, such that if $g(xi )xi geq 0$ for $|xi |geq xi _0$ and $limsup _{|xi |o infty } 2G(xi )/xi ...

Impact of APOE ε4 Genotype Load on Cognitive Function and Lipid Metabolism in Patients With Cerebral Small Vessel Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Apolipoprotein ε4 (APOE ε4) is a potent genetic risk factor for Alzheimer's disease (AD). However, its role in cerebral small vessel disease (CSVD) remains unclear. Given the clinical and pathological similarities between CSVD and AD, this study aimed to investigate the associations of APOE ε4 gene dosage with cognitive function and

On second order periodic boundary-value problems with upper and lower solutions in the reversed order

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we study the differential equation with the periodic boundary value $$displaylines{ u''(t)=f(t, u(t), u'(t)),quad tin [0, 2pi]cr u(0)=u(2pi), quad u'(0)=u'(2pi).

Amyotrophic Lateral Sclerosis Prevalence Projection in 2040: A Less Rare Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To project ALS prevalence across multiple countries through 2040, accounting for both population aging and increased survival. Methods Data from the Piemonte and Valle d'Aosta ALS register (PARALS) was used to estimate the trends in incidence and prevalence from 2005 to 2019. Survival trends over this period were also assessed.

Almost periodic solutions of higher order differential equations on Hilbert spaces

open access: yesElectronic Journal of Differential Equations, 2010
We find necessary and sufficient conditions for the differential equation $$ u^{(n)}(t) = Au(t)+f(t), quad tin mathbb{R} $$ to have a unique almost periodic solution. Some applications are also given.

The MMP‐9/TIMP‐1 Ratio and Concentrations of Osteopontin Are Elevated in Cerebrospinal Fluid of People With Multiple Sclerosis and Decrease After Autologous Hematopoietic Stem Cell Transplantation

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To evaluate the utility of cerebrospinal fluid (CSF) biomarkers—matrix metalloproteinase‐9 (MMP‐9), tissue inhibitor of metalloproteinases‐1 (TIMP‐1), the MMP‐9/TIMP‐1 ratio, and osteopontin (OPN)—as indicators of blood–brain barrier (BBB) integrity and disease activity in people with relapsing–remitting multiple sclerosis (pwMS ...

The Relationship Between Inflammation and Central Nervous System in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Aim Multiple sclerosis is an autoimmune demyelination disease that is seen especially in the young population and has a progressive course, causing motor, sensory, and cognitive deficits. In the literature, the pathogenesis of MS disease and the interconnection between the immune and central nervous system in the disease have not been fully ...

Existence of multiple periodic solutions for second-order discrete Hamiltonian systems with partially periodic potentials

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we use critical point theory to obtain multiple periodic solutions for second-order discrete Hamiltonian systems, when the nonlinearity is partially periodic and its gradient is linearly and sublinearly bounded.
