Electrocautery ablation therapy for anal intraepithelial carcinoma with high-resolution anoscopy.

Objective: This study investigated the efficacy and safety of electrocautery ablation for high-grade squamous intraepithelial lesions (HSILs) in men who have sex with men (MSM) including people with human immunodeficiency virus, using comprehensive biopsy with high-resolution anoscopy (HRA).

Methods: This single-arm, open-label pilot study included 20 MSM with HSIL who were treated with electrocautery ablation. The participants were recruited from the National Center for Global Health and Medicine and followed up using HRA with a comprehensive biopsy approach at 3- and 6-months post-ablation.

Pinhole Descending Aortic Rupture with Systemic Sclerosis and Dermatomyositis: A Case Report.

Thoracic descending aortic perforation with overlap syndrome (systemic sclerosis and dermatomyositis) is a rare, unreported vascular pathology. We describe the case of a 75-year-old woman who presented with chest tightness, back pain, and dyspnea. Computed tomography revealed a pinhole rupture in the descending aorta.

Electromyography of Flight Muscles in Free-Flying Chestnut Tiger Butterfly, .

The chestnut tiger butterfly, , can undertake long-distance migrations. They flap their wings for power flight and hold the wings for gliding; such repertoires of wing movements may be the key to explaining their excellent flight abilities. Measuring flight muscle activity using the electromyogram (EMG) is the first step toward understanding the neuromuscular mechanism of active flight control.
