Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Physics of Protein Aggregation in Normal and Accelerated Brain Aging

BioEssays, EarlyView.
Soluble monomeric proteins precipitate via nucleation into insoluble amyloids in response to age‐related exposures (e.g., microbes, nanoparticles). Persistent soluble‐to‐insoluble phase transition depletes the functional proteins. In normal aging, replacement matches loss; in accelerated aging, it does not.

Memory Gate Controlled by Contexts: Potential Key Structure That Could Link Small Associative Failures With Severe Cognitive Disorders

BioEssays, EarlyView.
Memory gate (MG) hypothesis assumes a neural structure that connects inputs to appropriate contexts. Panel A shows an input (green) that, in the MG, does not match the context (red): memory does not recognize it. Panel B shows that, in the MG, the context (green) matches the input: memory recognizes the pattern.
