Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

Prescribed pharmaceutical alternatives initiative coinciding with reductions in unregulated street opioid use among young people who use drugs: An interrupted time series analysis. [PDF]

Addiction
Abstract Background and aims In British Columbia, Canada, an initiative was implemented in 2020 to reduce overdose mortality by prescribing pharmaceutical opioids (primarily hydromorphone) as a substitute for the toxic unregulated drug supply. This study estimated changes in the level and trend of unregulated opioid use and non‐prescribed hydromorphone

Placebo Effect in Levodopa‐Induced Dyskinesia: A Systematic Review and Meta‐Analysis

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Levodopa‐induced dyskinesia (LID) is a complication of Parkinson's disease (PD) treatment. While the placebo effect is a known component in PD clinical trials, its specific magnitude in the context of LID is not well characterized.

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

PLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Smuggling Sovereignty: Trade, Transgression, and State Authority

Economic Anthropology, EarlyView.
ABSTRACT Global supply chains are saturated with transgressions—corruption, smuggling, document forgery, and other practices that blur the line between legality and illegality. States do not merely endure these practices; they actively shape the conditions for them, producing the very illegal systems they then claim to police.

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

Smart Molecules, EarlyView.
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

An Outline of a Theory of Play

Symbolic Interaction, EarlyView.
Play is often dismissed as trivial, yet it is a fundamental and adaptive aspect of human and mammalian life. This paper develops a sociological theory of play, treating it as a total social fact that spans biological, psychological, and social dimensions.
