Background & Aims: Gut-directed hypnotherapy (GDH) is effective for treating irritable bowel syndrome (IBS), but access limits its widespread use. We report the first randomized controlled trial comparing the safety and efficacy of a self-administered, digital GDH treatment program with that of digital muscle relaxation (MR) in adults with IBS.

Methods: After a 4-week run-in period, patients were randomized to 12 weeks of treatment with digital GDH (Regulora), or digital MR accessed via a mobile app on a smartphone or tablet.

Background: Ixmyelocel-T is an expanded, multicellular therapy produced from a patient's own bone marrow by selectively expanding two key types of bone marrow mononuclear cells: CD90+ mesenchymal stem cells and CD45+ CD14+ auto-fluorescent+ activated macrophages. Early phase clinical trials suggest that intramyocardial delivery of ixmyelocel-T might improve clinical, functional, symptomatic, and quality-of-life outcomes in patients with heart failure due to ischaemic dilated cardiomyopathy. We aimed to assess the safety and efficacy of catheter-based transendocardial injection of ixmyelocel-T cell therapy in patients with heart failure and reduced ejection fractions.

Ixmyelocel-T is an investigational patient-specific, expanded, multicellular therapy produced from a patient's own bone marrow. It is produced by selectively expanding two key types of bone marrow mononuclear cells (BM-MNCs), CD90 mesenchymal stem cells (MSCs), and CD45CD14 autofluorescent, alternatively activated macrophages. Earlier clinical trials suggested that intramyocardial ixmyelocel-T might improve clinical, functional, symptomatic, and quality of life outcomes in patients with ischemic dilated cardiomyopathy (IDCM).

The inducible isoenzyme of nitric oxide synthase (iNOS) generates nitric oxide (NO) in inflammatory diseases such as asthma. The prodrug L-N6-(1-iminoethyl)lysine 5-tetrazole amide (SC-51) is rapidly converted in vivo to the active metabolite L-N6-(1-iminoethyl)lysine (L-NIL). Initially, we performed in vitro experiments in human primary airway epithelial cells to demonstrate that L-NIL causes inhibition of iNOS.
