Resting-state Abnormalities in Heroin-dependent Individuals [PDF]

Neuroscience, 2018
Drug addiction is a major health problem worldwide. Recent neuroimaging studies have shed light into the underlying mechanisms of drug addiction as well as its consequences to the human brain. The most vulnerable, to heroin addiction, brain regions have been reported to be specific prefrontal, parietal, occipital, and temporal regions, as well as, some

Bromazolam Tablet Quantification and Analysis of Post‐Mortem Cases From the National Programme on Substance Use Mortality (NPSUM)

Drug Testing and Analysis, EarlyView.
Tablets submitted to drug checking services that were found to contain bromazolam. Over half of these counterfeit tablets mimicked the appearance of licensed formulations (e.g., alprazolam Xanax bars and diazepam Roche 10 mg pills). Bromazolam is now the most commonly detected street benzodiazepine in drug poisoning deaths in the United Kingdom ...

Promoting Safe Opioid Disposal: Experimental Evidence on Behavioral Messaging With Financial Incentives

Health Economics, EarlyView.
ABSTRACT Some patients prescribed opioid pills fail to properly dispose of their unused pills, posing a risk for others. We report results from a pre‐registered field experiment testing whether behaviorally informed reminder cards increase participation in a financial incentive program for returning unused opioid pills among U.S. Veterans.

Decreased Relative Cerebral Blood Flow in Unmedicated Heroin-Dependent Individuals

Frontiers in Psychiatry, 2020
Understanding the brain mechanisms of heroin dependence is invaluable for developing effective treatment. Measurement of regional cerebral blood flow (CBF) provides a method to visualize brain circuits that are functionally impaired by heroin dependence.

Assessing cue-induced brain response as a function of abstinence duration in heroin-dependent individuals: an event-related fMRI study. [PDF]

PLoS ONE, 2013
The brain activity induced by heroin-related cues may play a role in the maintenance of heroin dependence. Whether the reinforcement or processing biases construct an everlasting feature of heroin addiction remains to be resolved.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
