900-930 / 1000+ resultsresearch Establishing and Verifying a Robust Liquid Chromatography-Tandem Mass Spectrometry Method to Simultaneously Measure Seven Androgens Present in Plasma Samples
The method accurately measures seven androgens in plasma and shows different hormone levels in females with acne and obesity.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
