Activated Src kinase promotes cell cannibalism in Drosophila.

Src family kinases (SFKs) are evolutionarily conserved proteins acting downstream of receptors and regulating cellular processes including proliferation, adhesion, and migration. Elevated SFK expression and activity correlate with progression of a variety of cancers. Here, using the Drosophila melanogaster border cells as a model, we report that localized activation of a Src kinase promotes an unusual behavior: engulfment of one cell by another.

Treatment of superficial venous insufficiency in a large patient cohort with retrograde administration of ultrasound-guided polidocanol endovenous microfoam versus endovenous laser ablation.

Objective: To evaluate outcomes among symptomatic patients with superficial chronic venous insufficiency treated with retrograde ultrasound-guided polidocanol endovenous microfoam 1% (PEM) or endovenous laser ablation (EVLA).

Methods: This study is a retrospective chart review from a single vein center between October 2013 and June 2019. Procedures were performed on 1070 patients with Clinical, Etiologic, Anatomic, and Pathophysiologic class 2 to 6 disease and symptomatic superficial venous reflux of the great saphenous vein or anterior accessory saphenous vein.

Automated virtual reality exposure therapy for spider phobia vs. in-vivo one-session treatment: A randomized non-inferiority trial.

This study compared the efficacy of a technician-assisted single-session virtual reality exposure therapy (VRET) for the treatment of spider phobia featuring low-cost consumer-available hardware and novel automated software to gold-standard in-vivo one-session treatment (OST), using a parallel group randomized non-inferiority design. Method Participants (N = 100) were randomized to VRET and OST arms. Assessors blinded to treatment allocation evaluated participants at pre- and post-treatment as well follow-up (3 and 12 months) using a behavioral approach test (BAT) and self-rated fear of spider, anxiety, depression and quality-of-life scales.

Retrograde administration of ultrasound-guided endovenous microfoam chemical ablation for the treatment of superficial venous insufficiency.

Objective: This study measured patient outcomes among symptomatic patients with superficial chronic venous insufficiency who were treated with retrograde ultrasound-guided polidocanol microfoam 1% in a community setting.

Methods: Between March 2015 and June 2017, 250 symptomatic patients with C2-C6 chronic venous insufficiency received polidocanol microfoam 1% and were followed for 16 ± 7 months. Sixteen of the 250 patients (6.
