Researchers induced a hibernation-like state in mice by using ultrasound to stimulate the hypothalamus preoptic area in the brain, which helps to regulate body temperature and metabolism. The findings show the first noninvasive and safe method to induce such a state; a similar condition has been previously proposed for spaceflight or for patients with life-threatening health conditions. ....
Some mammals and birds have a clever way to preserve energy and heat by going into torpor, during which their body temperature and metabolic rate drop. Researchers at Washington University in St. Louis safely and noninvasively induced a torpor-like state in mice and rats by using ultrasound to stimulate the hypothalamus preoptic area in the brain. ....
Static magnetic field from MRI scanner decreases blood-brain barrier opening volume MRI-guided focused ultrasound combined with microbubbles can open the blood-brain barrier (BBB) and allow therapeutic drugs to reach the diseased brain location under the guidance of MRI. It is a promising technique that has been shown safe in patients with various brain diseases, such as Alzheimer s diseases, Parkinson s disease, ALS, and glioblastoma. While MRI has been commonly used for treatment guidance and assessment in preclinical research and clinical studies, until now, researchers did not know the impact of the static magnetic field generated by the MRI scanner on the BBB opening size and drug delivery efficiency. ....
