Selective Determination of Mercury Ion in River Water by Solvent Extraction with 4,6‐Dimethyl‐2‐Mercaptopyrimidine Followed by Reversed‐Phase HPLC

Autor: Susumu Ichinoki, Youichi Fujii, Yukiko Nagura

Publikováno v: Journal of Liquid Chromatography & Related Technologies. 31:1314-1323

A selective determination method for mercury (Hg) ion in river water has been developed by solvent extraction, followed by reversed‐phase HPLC with photometric detection. The Hg(II) ion was quantitatively extracted into chloroform over the pH range

Studies on Neurosteroids XXV. Influence of a 5.ALPHA.-Reductase Inhibitor, Finasteride, on Rat Brain Neurosteroid Levels and Metabolism

Autor: Yukiko Nagura, Kazutake Shimada, Tatsuya Higashi, Yoshiyuki Mukai

Publikováno v: Biological and Pharmaceutical Bulletin. 31:1646-1650

In this study, we examined the influence of finasteride (FIN), a 5alpha-reductase inhibitor, on the brain levels and metabolism of neurosteroids [allopregnanolone (AP), 3alpha-dihydroprogesterone (3alpha-DHP), progesterone (PROG), 20alpha-dihydroprog

Studies on Neurosteroids XXVI. Fluoxetine-Evoked Changes in Rat Brain and Serum Levels of Neuroactive Androgen, 5.ALPHA.-Androstane-3.ALPHA.,17.BETA.-diol

Autor: Kazutake Shimada, Toshimasa Toyo'oka, Yukiko Nagura, Tatsuya Higashi

Publikováno v: Biological and Pharmaceutical Bulletin. 32:1636-1638

It is well known that fluoxetine (Fluox), a selective serotonin reuptake inhibitor, increases the brain content of allopregnanolone (AP), a potent neuroactive steroid that positively modulates the action of gamma-aminobutyric acid (GABA) at the GABA

Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5alpha-androstane-3alpha,17beta-diol, in rat brain and serum using liquid chromatography-tandem mass spectrometry

Autor: Tadashi Nishio, Hiroyuki Yokoi, Kazutake Shimada, Tatsuya Higashi, Yukiko Nagura

Publikováno v: Biomedical chromatography : BMC. 22(12)

The development and validation of liquid chromatography-electrospray ionization-tandem mass spectrometric (LC-ESI-MS/MS) methods that enable the quantification of neuroactive androgens, androsterone (5alpha-androstan-3alpha-ol-17-one, 3alpha,5alpha-A
