Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

TWEAK/Fn14 Signaling Drives Oxidative Cardiac Injury in Systemic Lupus Erythematosus: Evidence From Patient Biomarker Studies, Lupus Mouse Models, and Cardiomyocyte Assays

open access: yesArthritis &Rheumatology, EarlyView.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/fibroblast growth factor–inducible 14 (Fn14) signaling in SLE‐related ...

Tissue Damage in Rheumatoid Arthritis Is Genetically Linked to Low Peptidylglycine Alpha‐Amidating Monooxygenase Activity in Synovial Fibroblasts

open access: yesArthritis &Rheumatology, EarlyView.
Objective Both susceptibility to, and severity of, rheumatoid arthritis (RA) is associated with the rs26232 C allele. Our primary aim was to identify the biologic mechanism underlying this association. Methods Expression of surrounding genes was compared among rs26232 genotypes.

Higher complement C4 gene copy number constitutes a shared genetic risk factor for giant cell arteritis and IgA vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Technique for Lateral Opening Wedge Distal Femoral Osteotomy Using Patient‐Specific Instrumentation for Genu Valgum and Patellar Instability

open access: yesArthroscopy Techniques, EarlyView.
Abstract Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft‐tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft ...
