Performance Evaluation of Composite Antisalt Agents and the Antisalt Dynamics Simulation Mechanism.

The conventional ferrocyanide complex ([Fe(CN)]) has been widely used as a scale inhibitor under mild conditions, but its oxidation at high temperature compromises the subsequent wastewater treatment processes. To conquer the inadequacies of Fe(CN)], aminotriacetamide (NTA) was synthesized using chloroacetic acid as an initial material and its molecular structure was characterized using FT-IR spectroscopy, H-NMR, and TGA. NTA was exploited in combination with polyaspartic acid (PASP) and sodium dodecyl benzene sulfonate (SDBS) to prepare a high-performance antisalt composite, and the scaling inhibitor performance was evaluated.

Peripheral immunological features of COVID-19 patients in Taizhou, China: A retrospective study.

Background: Abnormal peripheral immunological features are associated with the progression of coronavirus disease 2019 (COVID-19).

Methods: Clinical and laboratory data were retrieved in a cohort of 146 laboratory-confirmed COVID-19 patients. Potential risk factors for the development of severe COVID-19 were evaluated.

Effects of hydrosalpinx on ultrasonographic parameters for endometrial receptivity during the window of implantation measured by power color Doppler ultrasound.

Aim: The aim of this study is to assess the effects of hydrosalpinx on ultrasonographic parameters for endometrial receptivity during the window of implantation, as measured by power color Doppler ultrasound.

Methods: The women recruited to this study included sixty with unilateral or bilateral hydrosalpinx and fifty-seven prior to in vitro fertilization-embryo transfer (IVF-ET) or artificial insemination (AI) performed due to male infertility. Ultrasonographic parameters for endometrial receptivity were measured during the window of implantation by power color Doppler ultrasound.

Application of Combined Two-Dimensional and Three-Dimensional Transvaginal Contrast Enhanced Ultrasound in the Diagnosis of Endometrial Carcinoma.

Objective. The goal of this study was to explore the clinical value of combining two-dimensional (2D) and three-dimensional (3D) transvaginal contrast-enhanced ultrasounds (CEUS) in diagnosis of endometrial carcinoma (EC). Methods.

Comparative bioavailability and pharmacokinetics of sirolimus tablets in healthy Chinese volunteers.

Objectives: Although sirolimus tablets and oral solutions have been used in clinical practice, no study has been reported on the pharmacokinetics and bioavailability of a single-dose of sirolimus tablets in healthy Chinese volunteers. The purpose of this study was to compare the bioavailability and pharmacokinetic (PK) properties of two different 1-mg sirolimus tablets in healthy Chinese male volunteers and evaluate whether a generic tablet of sirolimus meets the criteria for bioequivalence from the State Food and Drug Administration (SFDA) of China when compared with a reference product.

Materials And Methods: A total of 24 healthy Chinese volunteers was eligible for this 6 mg single dose, randomized-sequence, open-label, 2-period crossover study.

Relative bioavailability and pharmacokinetic comparison of two different enteric formulations of omeprazole.

In order to comply with the requirements for a drug listed in China, the study was developed to compare the pharmacokinetics and relative bioavailability of two different enteric formulations of omeprazole (OPZ) in healthy Chinese subjects. A total of 32 volunteers participated in the study. Plasma concentrations were analyzed by nonstereospecific liquid chromatography/tandem mass spectrometric (LC-MS/MS) method.

Determination of lansoprazole in human plasma by rapid resolution liquid chromatography-electrospray tandem mass spectrometry: application to a bioequivalence study on Chinese volunteers.

A simple, sensitive and rapid LC/MS/MS method was developed for the quantification of lansoprazole in human plasma. After a simple sample preparation procedure by one-step protein precipitation with acetonitrile, lansoprazole and the internal standard bicalutamide were chromatographed on a Zorbax SB-C(18) (3.0 mm x 150 mm, 3.

Determination of risperidone in human plasma by HPLC-MS/MS and its application to a pharmacokinetic study in Chinese volunteers.

This study presents a rapid, specific and sensitive liquid chromatography/tandem mass spectrometry (LC-MS/MS) assay for determination of risperidone (RIS) in human serum using paroxetine as an internal standard (IS). An Alltima-C18 column (2.1 mmx100 mm, 3 microm) and a mobile phase consisting of 0.

[Study on determination of desloratadine in human serum and its pharmacokinetics by HPLC/MS].

Objective: To study the determination of desloratadine in human serum and its pharmacokinetics in healthy volunteers.

Methods: A single oral dose of 10 mg desloratadine was given to 18 healthy volunteers. The serum concentrations of desloratadine were determined by HPLC-MS assay.
