A linguistic analysis of dehumanization toward substance use across three decades of news articles

Featured Paper of the Month – April 2024

Published in Frontiers in Public Health by Salvatore Giorgi and Brenda Curtis, et al. of the NIDA IRP Technology and Translational Research Unit.

In this work, we apply a computational linguistic framework to measure dehumanization to 3 million news articles. We show that popular media in the U.S. has dehumanized people who used substances to varying degrees. Substances such as heroin have been strongly dehumanized for decades, while marijuana use is becoming less dehumanized over time, aligning with increased public support for legalization.

µ-Opioid receptor antagonism facilitates the anxiolytic-like effect of oxytocin in mice

Hot Off the Press – March 26, 2024 Published in Translational Psychiatry by Khalin Nisbett, Leandro Vendruscolo and George Koob from the NIDA IRP Stress & Addiction Neuroscience Unit and Neurobiology of Addiction Section. Summary Nisbett et al. discovered that the anxiolytic-like (anxiety-reducing) effect of oxytocin can be modulated by the endogenous opioid system. We… [Read More]

Brain Functional Connectome Defines a Transdiagnostic Dimension Shared by Cognitive Function and Psychopathology in Preadolescents

Featured Paper of the Month – March 2024
Published in Biological Psychiatry by Xiang Xiao and Yihong Yang, et al. of the NIDA IRP Magnetic Resonance Imaging and Spectroscopy Section.

Cognitive function and general psychopathology are two important classes of human behavior dimensions that are individually related to mental disorders across diagnostic categories. However, whether these two transdiagnostic dimensions are linked to common or distinct brain networks that convey resilience or risk for the development of psychiatric disorders remains unclear.

Alkoxy chain length governs the potency of 2-benzylbenzimidazole ‘nitazene’ opioids associated with human overdose

Featured Paper of the Month – February 2024
Published in Psychopharmacology by Grant Glatfelter and Michael Baumann et al. of the NIDA IRP Designer Drug Research Unit.

Our findings reveal that nitazenes are potent mu-opioid receptor agonists that induce opioid-like effects in mice. Importantly, we show that certain analogs (e.g., isotonitazene, etonitazene) are much more potent than fentanyl, portending serious risk of overdose and other adverse effects in humans who are exposed to the drugs.

Using a novel rapid alternating steering angles pulse sequence to evaluate the impact of theranostic ultrasound-mediated ultra-short pulse length on blood-brain barrier opening volume and closure, cavitation mapping, drug delivery feasibility, and safety Theranostics.

The current study from the Konofagou lab describes an advancement in FUS delivery parameters and instrumentation that allows the simultaneous opening and monitoring of BBB in two brain regions simultaneously. This preclinical study highlights new developments in FUS that expand its capabilities for safe, non-invasive gene and drug delivery to the brain for the potential treatment of neurological diseases. FUS may be a useful tool for evaluating therapeutics for substance use disorder.
