Increased myocardial blood flow during acute exposure to simulated altitudes [PDF]

, 2018
Background: Although only poor data exist on changes in myocardial blood flow (MBF) under acute hypoxia, patients with known coronary artery disease are advised not to exceed a moderate altitude exposure of about 2000 m above sea level.

Lung‐Penetrating Biomimetic Extracellular Vesicle Spherical Nucleic Acids for Pulmonary Fibrosis Therapy Through ROS Scavenging and Anti‐Inflammatory Effects

Aggregate, EarlyView.
This work describes a biomimetic extracellular vesicle‐spherical nucleic acid (BEV‐SNA) platform for idiopathic pulmonary fibrosis (IPF) therapy. BEV‐SNA is composed of mechanically extruded BEVs from primary MSCs and cholesterol‐modified ssDNA that are assembled through hydrophobic interactions.

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

Advanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.
