Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Oscillatory and non-oscillatory solutions of dynamic equations with bounded coefficients

open access: yesElectronic Journal of Differential Equations, 2018
We analyze second-order half-linear dynamic equations on time scales. We prove oscillation and non-oscillation criteria which are sharp in the sense that the considered equations remain uncovered only for one setting of their coefficients.

Nonoscillatory half-linear difference equations and recessive solutions

open access: yesAdvances in Difference Equations, 2005
This paper is concerned with recessive and dominant solutions for the nonoscillatory second-order half-linear difference equations \[ \Delta(a_{n}\Phi(x_{n}))+b_{n}\Phi(x_{n+1})=0, \] where \(\Delta x_{n}=x_{n+1}-x_{n}\), \(\Phi(u)=| u| ^{p-2}u\) with \(p>1\), and \(\{a_{n}\},\{b_{n}\}\) are positive real sequences for \(n\geq1\). By using a uniqueness

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

Oscillation criteria for second-order neutral delay differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
New sufficient conditions for oscillation of second-order neutral half-linear delay differential equations are given. Our results essentially improve, complement and simplify a number of related ones in the literature, especially those from a recent ...

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

A remark on the linearization technique in half-linear oscillation theory [PDF]

open access: yesOpuscula Mathematica, 2006
We show that oscillatory properties of the half-linear second order differential equation \[(r(t)\Phi(x'))'+c(t)\Phi(x)=0,\qquad\Phi(x)=|x|^{p-2}x,\quad p\gt 1,\] can be investigated via oscillatory properties of a certain associated second order linear ...

Homogenization of a parabolic Dirichlet problem by a method of Dahlberg

open access: yes, 2016
Consider the linear parabolic operator in divergence form $$\mathcal{H} u =\partial_t u(X,t)-\text{div}(A(X)\nabla u(X,t)).$$ We employ a method of Dahlberg to show that the Dirichlet problem for $\mathcal{H}$ in the upper half plane is well-posed for ...

Sharp oscillation criteria for fourth order sub-half-linear and super-half-linear differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
Summary: This paper is concerned with the oscillatory behavior of the fourth-order nonlinear differential equation \[ \bigl(p(t)|x^{\prime\prime}|^{\alpha-1}\,x^{\prime\prime}\bigr)^{\prime\prime}+q(t)|x|^{\beta-1}x=0\,,\tag{E} \] where \(\alpha>0, \beta>0\) are constants and \(p,q:[a,\infty)\to(0,\infty)\) are continuous functions satisfying the ...

GAD65 Antibody ELISA With Extended Reportable Range: Validation and Guidance for Neurological Practice

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To (1) validate GAD65‐ELISA detection and quantification for type 1 diabetes mellitus and autoimmune neurological diagnoses, (2) correlate ELISA results (reference range < 5 IU/mL) with established radioimmunoprecipitation assay (RIA; ≤ 0.02 nmol/L), and (3) define ELISA clinical utility and pitfalls.
