Association between antenatal depression and adverse perinatal outcomes: a prospective cohort study.

Background: Antenatal depression might cause adverse pregnancy outcomes. However, previous study results were inconsistent, especially in the low- and middle- income countries. We aimed to study the association between antenatal depression and adverse perinatal outcomes in a Chinese population.

Cyclic Trinuclear Copper(I) Complex Exhibiting Aggregation-Induced Emission: A Novel Fluorescent Probe for the Selective Detection of Gold(III) Ions.

Coordination complexes with aggregation-induced-emission (AIE) behavior has drawn much attention because of their promising applications. Conventionally, the AIE-active metal-organic complexes are prepared from an AIE-active organic ligand, and the construction of such coordination complexes from aggregation-caused-quenching (ACQ) ligands is still challenging. Herein, we have synthesized two new cyclic trinuclear complexes (CTCs), namely, and , from copper(I) and silver(I) and a ACQ ligand [4-(3,5-dimethyl-1-pyrazol-4-yl)benzaldehyde, ].

Realization of Ethylene Production from Its Quaternary Mixture through Metal-Organic Framework Materials.

Ethylene production from oxidative coupling of methane is a sustainable and economically attractive alternative to that through traditional hydrocarbon cracking technology. However, efficient ethylene separation from the complex reaction mixture is a daunting challenge that hinders the practical adoption of this technology. Herein, we report the efficient adsorptive separation of the CH/CO/CH/CH mixture using three representative metal-organic frameworks (MOFs) (UTSA-74, MOF-74, and HKUST-1) with diverse open metal sites.

[Hydrochemical Characteristics and Possible Controls of the Surface Water in Ranwu Lake Basin].

To study the chemistry of surface water and potential control measures in the Ranwu Lake basin, 19 samples were collected from Ranwu Lake in 2019. Conventional hydrochemical techniques and statistical analysis methods (descriptive statistics, the Gibbs figure, ion ratio, Piper triangular diagrams) were applied to better understand the solute geochemistry and surface water hydrochemistry in the Ranwu Lake catchment. Surface water in the Ranwu catchment is slightly alkaline (pH of the samples ranged from 7.

Doubly Interpenetrated Metal-Organic Framework of pcu Topology for Selective Separation of Propylene from Propane.

Adsorptive separation is an appealing alternative technology to reduce the high energy and capital cost of the distillation separation of propylene/propane; however, it is very challenging to realize. A new flexible metal-organic framework (MOF) material [Zn(BDC-Cl)(PyTTz)] with a doubly interpenetrated pillared paddle wheel structure of (primitive cubic) topology has been realized for this difficult separation for the first time. Through a judicious choice of linkers, the framework has small pore apertures that lead to much more propylene adsorption than propane.

The browning of white adipose tissue and body weight loss in primary hyperparathyroidism.

Background: Parathyroid hormone related protein (PTHrP) triggers white adipose tissue (WAT) browning and cachexia in lung cancer mouse models. It remains unknown whether excessive PTH secretion affects WAT browning and to what extent it contributes to body weight change in primary hyperparathyroidism (PHPT).

Methods: Using the adeno-associated virus injection, Pth gene over-expressed mice mimicking PHPT were firstly established to observe their WAT browning and body weight alteration.

[Major Ionic Features and Their Possible Controls in the Water of the Niyang River Basin].

In order to study the hydrochemical characteristics and their possible controls for the chemical composition of the water from the Niyang River Basin, 30 samples were collected from wells, springs, and the river in 2014 and major ion concentrations were measured. Descriptive statistics, the Gibbs figure, an ion ratio, and Piper triangular diagrams were used to investigate the hydrochemical characteristics, influencing factors, and hydrochemical evolution of the water in the basin. The results showed that the major cations in this water were Ca and Mg, accounting for more than 84% of cations and the main anions were HCO and SO, accounting for more than 97% of anions The hydrochemical typology of the water is HCO·SO(SO·HCO)-Ca·Mg (Mg·Ca).

UPLC-MS-MS Determination of Dihydrocodeine in Human Plasma and Its Application to a Pharmacokinetic Study.

A sensitive and rapid ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS-MS) method was developed to determine dihydrocodeine (DHC) in human plasma using diazepam as the internal standard (IS). Sample preparation was accomplished through a liquid-liquid extraction procedure with ethyl acetate. The analyte and IS were separated on an Acquity UPLC BEH C18 column (2.

Determination of kurarinone in rat plasma by UPLC-MS/MS.

A sensitive and rapid ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed to determine kurarinone in rat plasma using chlorzoxazone as the internal standard (IS). Sample preparation was accomplished through a liquid-liquid extraction procedure with ethyl acetate to 0.2 mL plasma sample.

[Observation of clinical effect of vertically fractured molar teeth treated with elastic ligation].

Purpose: To evaluate the clinical effect of vertically fractured posterior teeth treated with elastic ligation.

Methods: Eighty-six vertically fractured posterior teeth were chosen to be treated with elastic ligation for external fixation before root canal therapy (RCT), and then full crown prostheses were made for rehabilitation.

Results: The success rate after 1 year, 2 years and 3 years were 97.
