Drug stability in forensic toxicology
WIREs Forensic Science, Volume 5, Issue 4, July/August 2023., 2023 The stability of analytes of interest in solvents and biological matrices depends on many factors, including time, storage conditions, pH, and temperature. It is essential for forensic toxicologists to understand sample preservation techniques and limitations, including analyte metabolism and degradation pathways, when interpreting antemortem and ...

The Scientific World Journal, Volume 2023, Issue 1, 2023., 2023 Halophytes have long been used for medicinal purposes. However, their use was entirely empirical, with no knowledge of the bioactive compounds. The plant Tamarix aphylla L. has not drawn the deserving attention for its phytochemical and bioactive explorations, but available data expressed its needs to be attended for its potential.

Electrochemical Science Advances, Volume 2, Issue 5, October 2022., 2022 Abstract A laboratory prototype of enzyme biosensor based on pH‐sensitive field‐effect transistors has been created to determine the total content of indole alkaloids in Rauwolfia serpentina tissue culture. Enzyme acetylcholinesterase was immobilized on the surface of pH‐sensitive field‐effect transistors using glutaraldehyde for covalent crosslinking ...

Extraction, radiolabeling, and biodistribution of thebaine in rats [PDF]
Medicinal Chemistry Research, 2012 The goal of this study was to determine the radiopharmaceutical potential of radioiodinated thebaine. Thebaine was extracted from dry capsules of opium poppy (Papaver somniferum L.), purified using high-performance liquid chromatography, and characterized with nuclear magnetic resonance and infrared spectroscopy.

Establishment to measure oxycodone in plasma with liquid chromatography–tandem mass spectrometry
Neuropsychopharmacology Reports, Volume 42, Issue 3, Page 299-305, September 2022., 2022 Abstract Oxycodone (OXY) is classified as a “strong opioid” in the World Health Organization system of cancer pain treatment. However, OXY also causes severe adverse reactions, such as respiratory depression. Thus, in order to adjust the dosage of OXY for well‐managed pain relief with less toxicity, we tried establishing and validating a system for ...
