Optimization of microRNA extraction from the plasma of the common carp.

Efficient and safe extraction of microRNAs (miRNAs) from biological samples is pivotal for genetic regulation studies and biotechnological applications. This study focuses on optimizing the microRNA extraction process from the plasma of common carp, a significant species in aquaculture. Recognizing the limitations and hazards of commercial extraction kits, which often employ toxic chemicals like phenol and chloroform, we sought to develop a safer and more effective alternative.

[Determination of five nitroimidazoles and six benzodiazepines in aquatic products using ultra-high performance liquid chromatography-tandem mass spectrometry coupled with dispersive solid-phase extraction].

Nitroimidazoles (NMZs) are a crucial group of antibacterial compounds from a historical perspective. In the past, they were used for treating and preventing parasitic infections in fish. Benzodiazepines (BZDs) are second-generation sedative-hypnotics.
