Efficacy, safety, and pharmacokinetics of oral valganciclovir in patients with congenital cytomegalovirus infection.

Objectives: Valganciclovir (VGCV) has been shown to improve sensorineural hearing loss (SNHL) and neurological outcomes in patients with neonatal symptomatic congenital cytomegalovirus (cCMV) infection. However, reports on the pharmacokinetics, efficacy and safety of oral VGCV are limited. The aim of this study is to evaluate the pharmacokinetics of VGCV for use in the treatment of cCMV.

Effect of different shielding conditions on the stability of Cisplatin.

Background: Because cisplatin (CDDP) decreases upon light exposure, it is necessary to prevent such exposure during administration. However, the shielding conditions employed are not uniform. Therefore, in this study, we examined the shielding effects of four shading covers, which are commonly used to ensure the stability of CDDP in clinical settings.

Column switching high-performance liquid chromatography with two channels electrochemical detection for high-sensitive determination of isoflavones.

Column switching HPLC with electrochemical detection (HPLC-ED), which consists of one pre-column and two electrochemical detectors subsequent to each analytical column, called HPLC-2ED, has been developed for determining isoflavones (daidzin, genistin, daidzein, and genistein) with high sensitivity. In the present HPLC-2ED, the eluted daidzin and genistin from the pre-column were separated on an analytical column using a methanol-water-phosphoric acid mixture (30:70:0.5) as the mobile phase (MP), and daidzein and genistein were separated on another analytical column using a methanol-water-phosphoric acid mixture (50:50:0.
