Research in Brazil found that glycemic delta, a measure of blood sugar variability, is associated with the size of the heart attack and the strength of heart contractions. The study suggests that high glycemic delta may be a biomarker for worse outcomes in patients who have experienced their first acute myocardial infarction.
Researchers have discovered a simple way to protect atoms from losing information by shining a single laser beam on them, reducing spin relaxation rates. The technique uses light to subtly shift atomic energy levels, aligning spins and keeping them in sync even as they collide with each other or surroundings.
Researchers have developed procedures for using gold nanostars to perform more efficient, conformal, and safe laser ablations for treating brain tumors. This technique addresses limitations in traditional LITT by providing improved precision for lesions greater than 3 cm or with complex shapes.
A groundbreaking study has shown that a devastating heart condition can spontaneously reverse in three men, who are now free of symptoms. The condition, transthyretin cardiac amyloidosis, is progressive and previously considered irreversible.
