Synthesis, Structural and Behavioral Studies of Indole Derivatives D2AAK5, D2AAK6 and D2AAK7 as Serotonin 5-HT and 5-HT Receptor Ligands.

Serotonin receptors are involved in a number of physiological functions and regulate aggression, anxiety, appetite, cognition, learning, memory, mood, nausea, sleep, and thermoregulation. Here we report synthesis and detailed structural and behavioral studies of three indole derivatives: D2AAK5, D2AAK6, and D2AAK7 as serotonin 5-HT and 5-HT receptor ligands. X-ray studies revealed that the D2AAK5 compound crystallizes in centrosymmetric triclinic space group with one molecule in the asymmetric unit.

Morphometry of Boar Spermatozoa in Semen Stored at 17 °C-The Influence of the Staining Technique.

The aim of the study was to assess the morphometry of sperm during storage of liquid boar semen at 17 °C. An attempt was also made to evaluate the suitability of three staining methods for assessment of boar sperm morphometry. The study was carried out on 20 Landrace boars.

The comparison of dexketoprofen and other painkilling medications (review from 2018 to 2021).

Dexketoprofen is an enantiomer of ketoprofen (S+) that belongs to nonsteroidal anti-inflammatory drugs and has analgesic, anti-inflammatory, and antipyretic properties. Dexketoprofen has a stronger effect than ketoprofen, which makes it a readily used preparation. The review aims to find in recent original publications data about dexketoprofen and its comparison with other painkilling medications.
