Mutagenic activity of 33 psychotropic drugs was studied in Drosophila metanogaster according to the CLB method. The drugs are the following: leponex, neuleptil, randolectil, teralen, chlorprotixen, TPS-23, navane, pimosid, difenisid, rudotel, eunoktin, radedorm, meprobamat, trioxasin, elenium, napoton, aponal, lorasepam, nuredal, oxyphenonat, safrasin, surmantil, amitriptilin, prothioden, melipramin, saroten, tegretol, phenobarbital, diakarb, benzonal, suksilep, morpholep, sydnocarb. The increase in the mutation rate was induced by leponex (1.37% in adults and 1.21% in larvae), difenisid (1.18% in adults), two forms of the same drug eunoktin and radedorm (about 1.6% in adults), safrasin (1.06% in imago), saroten (1,36% in imago), phenobarbital (2.02% in imago). Even a slight increase of mutagenicity of widely spread psychotropic drugs is a very serious factor which needs further investigation and specification in other models and organisms.

Optimization of the manufacturing process based on scientific evidence is essential for quality control of active pharmaceutical ingredients. Real-time monitoring can ensure the production of stable quality crystals in the crystallization process. Raman spectroscopy is an attractive tool for pharmaceutical quality evaluation and process analytical technology because of its ability to analyze samples non-destructively and rapidly.

Chimeric antigen receptor T-cell (CAR-T) therapies have shown promise in glioblastoma clinical studies, but responses remain inconsistent due to heterogeneous tumor antigen expression and immune evasion post-treatment. NKG2D CAR-T cells have demonstrated a favorable safety profile in patients with hematologic tumors, and showed robust antitumor efficacy in various xenograft models, including glioblastoma. However, malignant glioma cells evade immunological surveillance by reducing NKG2D ligands expression or cleavage.

Background: Epoetin alfa is a derivative of the erythropoietin hormone. This study aims to investigate the epoetin alfa effect on anxiety-like behaviors.
Methods: Adult female Wistar Albino rats were divided into Control (n = 8), 1000 U Epoetien alfa, and 2000 U Epoetien alpha.
Esketamine alleviates depressive-like behavior in neuropathic pain mice through the METTL3-GluA1 pathway.

Esketamine, a newly developed antidepressant, is the subject of this research which seeks to explore its impact on depressive symptoms in neuropathic pain mice and the potential molecular mechanisms involved. Through transcriptome sequencing and bioinformatics analysis combined with in vivo studies, it was identified that esketamine markedly boosts the levels of the m6A methyltransferase METTL3 and the AMPA receptor GluA1 subunit. Esketamine activates METTL3, allowing it to bind with GluA1 mRNA, promoting m6A modification, thereby enhancing GluA1 expression at synapses.

Recreational use of nitrous oxide (NO) has risen dramatically over the past decades. This study aimed to examine its rewarding effect and the underlying mechanisms. The exposure of mice to a subanesthetic concentration (20%) of NO for 30 min for 4 consecutive days paired with NO in the morning and paired with the air in the afternoon produced apparent rewarding behavior in the conditioned place preference (CPP) paradigm.
