Timing Is Everything: How Subtle Timing Changes in MRI Echo Planar Imaging Can Significantly Alter Mechanical Vibrations and Sound Level

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3116-3130, June 2026.
ABSTRACT Purpose Echo‐Planar Imaging (EPI) is central to fMRI, diffusion MRI, and many dynamic clinical applications, yet rapid gradient switching induces strong mechanical vibrations, generates acoustic noise, and contributes to ghosting artifacts—effects that intensify at ultra‐high fields.

Immortalization of Human Adult Alveolar Epithelial Cells to Study Environmental Exposures of the Distal Lung

Current Protocols, Volume 6, Issue 5, May 2026.
Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.
