Dicyclohexyl phthalate (DCHP) is one of the plasticizers. The objective present study was to investigate effects DCHP on fetal Leydig cell distribution and function as well testis development. Female pregnant Sprague Dawley dams orally received vehicle (corn oil, control) or (10, 100, 500 mg/kg/day) from gestational day (GD) 12 GD 21. At 21.5, testicular testosterone production, number distribution, gene protein expression levels were examined. administration produced a dose-dependent...

Abstract A sensitive and selective liquid chromatography–tandem mass spectrometry method for the determination of pethidine in human plasma was developed validated over concentration range 4–2000 ng/mL. After addition ketamine as internal standard, liquid–liquid extraction used to produce a protein‐free extract. Chromatographic separation achieved on 100 × 2.1 mm, 5 µm particle, Allure TM PFP propyl column, with 45:40:15 (v/v/v) acetonitrile–methanol–water containing 0.2% formic acid mobile...

A sensitive and selective liquid chromatography tandem mass spectrometry (LC-MS-MS) method for determination of urapidil hydrochloride in rabbit plasma was developed validated. After addition doxapram as the internal standard (IS), protein precipitation by 10% trichloroacetic acid used sample preparation. Chromatographic separation achieved on a Zorbax SB-C18 (2.1 mm × 50 mm, 3.5 μm) column with acetonitrile-water mobile phase gradient elution. Electrospray ionization (ESI) source applied...

Multiple sequence magnetic resonance imaging (MRI) is often hampered by noise and misalignment. The wavelet de-noising lacks directivity does not preserve image details, which limits its effectiveness. To solve the problem, an adaptive threshold method based on transformation employed. As to misalignment, a registration basis of shape context descriptor proposed accurately align multiple MR sequences. In order achieve better MRI capabilities, new criteria that distribution in high low sub...
