IMPORTANCE Short transverse myelitis (STM; <3 vertebral segments) is considered noncharacteristic of neuromyelitis optica (NMO) spectrum disorders (NMOSDs). Nonappreciation of the potential for STM to occur in NMOSD may lead to increased disability from delay in diagnosis and appropriate treatment. OBJECTIVES To determine the frequency of short lesions at(More)
OBJECTIVE To 1) determine, using contemporary recombinant antigen-based assays, the aquaporin-4 (AQP4)-immunoglobulin G (IgG) detection rate in sequential sera of patients assigned a clinical diagnosis of neuromyelitis optica (NMO) but initially scored negative by tissue-based indirect immunofluorescence (IIF) assay; and 2) evaluate the impact of serostatus(More)
OBJECTIVE To determine the sex and age distribution of aquaporin-4 (AQP4) autoimmunity using data derived from clinical service laboratory testing of 56,464 patient samples. DESIGN Observational analysis. SETTING Mayo Clinic Neuroimmunology Laboratory. PATIENTS Between October 1, 2005, and January 4, 2011, 56,464 patients were tested for AQP4-IgG;(More)
IMPORTANCE Studies focused on recurrent longitudinally extensive transverse myelitis (rLETM) are lacking. OBJECTIVES To determine the aquaporin 4 (AQP4) IgG detection rate using recombinant human APQ4-based assays in sequential serum specimens collected from patients with rLETM categorized as negative by first-generation tissue-based indirect(More)
OBJECTIVE To explore the etiologies and imaging features of longitudinally extensive spinal cord lesion (LESCL). METHODS The etiologies and magnetic resonance (MR) imaging features of 51 hospitalized LESCL patients from January 2011 to August 2013 were reviewed and retrospectively analyzed. RESULTS Among them, the causes were neuromyelitis optica(More)
A discrete-time predator-prey model is proposed with Leslie-type numerical response, and the asymmetrical influence of Allee effect on the proposed system is investigated. By mathematical analysis, locally stable conditions for the equilibrium points of the considered systems with or without Allee effect are obtained firstly. Furthermore, numerical(More)
OBJECTIVE To explore the clinical features and therapeutic profiles of autoimmune dementia. METHODS Eight hospitalized patients with autoimmune dementia during March 2011 and May 2013 were recruited and retrospectively analyzed for clinical features, as well as therapeutic and prognosis profiles. RESULTS There were 3 males and 5 females with a onset age(More)
OBJECTIVE To quantify serum uric acid (UA) levels in autoimmune myelopathy (AMs) patients and analyze the clinical relevance. METHODS Blood samples from hospitalized patients with AMs (n = 69) in acute phase and other neurological disorders (n = 50) between September 2009 and December 2013 and healthy subjects (n = 50) were used to detect UA level by(More)
We are concerned with the followingmodified nonlinear Schrödinger system: −Δu+u−(1/2)uΔ(u2) = (2α/(α+β))|u||V|u, x ∈ Ω, −ΔV+V−(1/2)VΔ(V2) = (2β/(α+β))|u||V|V, x ∈ Ω, u = 0, V = 0, x ∈ ∂Ω, whereα > 2, β > 2, α+β < 2⋅2, 2∗ = 2N/(N−2) is the critical Sobolev exponent, andΩ ⊂ RN (N ≥ 3) is a bounded smooth domain. By using the perturbationmethod, we establish(More)
