Naloxone (also known as Narcan, the commonly used drug to treat narcotic overdoses) has greater binding to opioid receptors in women’s brains than in men’s brains, according to new research published in the July issue of The Journal of Nuclear Medicine. The first-in-human whole-body PET study suggests men and women may respond differently to opioid use disorder treatments and offers new insights to advance neuropharmacology. 

Electronic cigarettes, or vapes, are widely used and available in hundreds of different types and flavors, yet researchers lack information about the everyday e-cigarette habits of young adults. The National Institutes of Health, in partnership with the U.S. Food and Drug Administration, has funded a University of Oklahoma study that will investigate how, when and why young adults use e-cigarettes and how that use may relate to health risks. The results will help the FDA make decisions about regulating the makers of e-cigarette products.
