Since the introduction of the European Early Warning System in 2005, >700 new psychoactive substances (NPS) have been listed. This review article presents for the first time the Swiss narcotic law in perspective of scheduling of NPS, and compares it to the regulations of the German speaking neighbours Austria and Germany. The Swiss way is a fast and effective way for scheduling NPS, with the purpose to restrict drug trafficking and for controlling the NPS drug market: the legal basis for scheduling substances of abuse is the "Law about narcotics and psychotropic substances" (BetmG, SR 812.121), which includes the "narcotic law directory (BetmVV-EDI, SR 812.121.11) suitable for listing all controlled substances. The BetmVV-EDI, SR 812.121.11 contains seven indices, with index e specifically designed for the fast scheduling of NPS. Newly appearing NPS can either be controlled under a structure analogues definition or by listing single substances. The list of single substances is updated at least once per year, and structure analogues definitions can be implemented, in order to keep track with new developments on the NPS market. The latest version from November 30th 2018 contains ten different structure analogue definitions and 207 single substances. Requirements to list NPS are their appearance on the NPS market, suspected psychotropic effects and their suggestions by Forensic professionals. As soon as substances are newly placed, on Schedule I of the 1961 Convention or Schedule II of the 1971 Convention by the Commission on Narcotic Drugs of the World Health Organization they can easily be transferred from index e to index a-d of the BetmVV-EDI, SR 812.121.11. The Austrian law uses a structure analogue and single substances approach (introduced in 2012, one update in 2016), whereas the German NPS law (established in 2016, no update yet) only lists two structure-analogue-definitions. All three legislations have defined which core structures, kinds and sites of substitutions are regulated.

The crowded bacterial cytoplasm is composed of biomolecules that span several orders of magnitude in size and electrical charge. This complexity has been proposed as the source of the rich spatial organization and apparent anomalous diffusion of intracellular components, although this has not been tested directly. Here, we use biplane microscopy to track the 3D motion of self-assembled bacterial genetically encoded multimeric nanoparticles (bGEMs) with tunable size (20 to 50 nm) and charge (-3,240 to +2,700 e) in live cells.

Ocular cystinosis is a disease in which accumulated cystine crystals cause damage to the eyes, necessitating timely treatment and ongoing monitoring of cystine levels. The current treatment involves frequent administration of cysteamine eye drops, which suffer from low bioavailability and can lead to drug toxicity, making it essential to prescribe an appropriate dosage based on the patient's condition. Additionally, cystine crystal levels are typically assessed subjectively via slit-lamp examination, requiring frequent clinical visits and causing discomfort for the patient.

Heat engines transform thermal energy into useful work, operating in a cyclic manner. For centuries, they have played a key role in industrial and technological development. Historically, only gases and liquids have been used as working substances, but the technical advances achieved in recent decades allow for expanding the experimental possibilities and designing engines operating with a single particle.

Endosymbionts are important for insect species as they provide essential substances to the host. Due to the technical advance of NGS technology and assemblers, many endosymbionts bacterial genomes are available now. Here, we analysed fourteen endosymbiont bacterial genomes of genius, one of notorious pest species.

There is growing concern that exposure to per/polyfluoroalkyl substances (PFAS), persistent chemicals used widely to make consumer products water- or grease-proof, may alter immune function, leading to reduced vaccine response or greater susceptibility to infections. We investigated associations between two legacy PFAS (PFOA and PFOS) and infant cytokine levels measured in newborn dried bloodspots (NDBS) from a large population-based birth cohort in Upstate New York, to determine whether exposure to legacy PFAS is associated with variability in cytokine profiles in newborns. We performed adjusted mixed effects regressions for each cytokine against PFOS and PFOA followed by exploratory factor analysis (EFA) on specific cytokine subsets selected via the prior regressions.
