Epstein–Barr Virus, Lower Vitamin D, Low Sun Exposure, and HLA‐DRB1*1501 Risk Variant Share Common Epigenetic Pathways Leading to Multiple Sclerosis Onset

Annals of Neurology, EarlyView.
Objectives Multiple sclerosis (MS) onset risk factors include Epstein–Barr virus (EBV) indices (including host response), lower serum 25‐vitamin D (25(OH)D) levels, low sun exposure, and HLA‐DRB1*1501. The underlying molecular mechanisms are unclear. Here, we examined mediation through differential DNA methylation (DNAm) to better understand possible ...

Existence of infinitely many homoclinic orbits for second-order systems involving Hamiltonian-type equations

Electronic Journal of Differential Equations, 2013
We study the second-order differential system $$ ddot u + Adot{u}- L(t)u+ abla V(t,u)=0, $$ where A is an antisymmetric constant matrix and $L in C(mathbb{R}, mathbb{R}^{N^2})$.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Understanding the Form and Timing of Damage to Archaeological Sites During the Syrian Conflict by Combining Evidence From Remote Sensing With Ground Observation

Archaeological Prospection, EarlyView.
ABSTRACT Satellite remote sensing is used widely to monitor damage to archaeological sites in conflict areas, including in Syria. On‐the‐ground assessments have been fewer in number, and the degree to which remote sensing assessments reflect what is happening on the ground has not been extensively tested.

Prognostic value of lupus anticoagulant and anti‐β2 glycoprotein I antibody in adverse pregnancy outcomes.

Arthritis &Rheumatology, Accepted Article.
Objective International criteria for antiphospholipid syndrome (APS) include lupus anticoagulant (LA), anticardiolipin (aCL) immunoglobulin (Ig) G and IgM, and anti‐β2‐glycoprotein I (β2GPI) IgG and IgM. However, evidence supporting their prognostic value or treatment efficacy in improving live birth rates is limited.
