Researchers studied mouse vagus nerve cells and found two small, separate groups of sensory neurons (called P2ry1 and Npy2r). Each group has only a few hundred neurons and sends dense branches into the lung but to different brainstem areas. Using optogenetics (light to activate chosen neurons), turning on P2ry1 neurons…
Researchers followed 100 outpatients (mean age 62) who kept having dizziness. They found that problems of the vestibular system (inner ear and balance) and psychiatric disorders were the most common causes. About half the patients had more than one factor making dizziness worse, and life‑threatening causes were rare.
Researchers exposed human airway epithelial cell cultures to vaping aerosols made from common e-liquid base (PG/VG), PG/VG with CBD oil, and PG/VG with CBD oil plus vitamin E acetate (VEA). They saw CBD oil and VEA stick to the airway surface and build up inside cells. After three daily exposures,…
