H* Species Regulation by Mn-Co(OH) for Efficient Nitrate Electro-reduction in Neutral Solution.

During the electrocatalytic NO reduction reaction (NO RR) under neutral condition, the activation of H O to generate H* and the inhibition of inter-H* species binding, are critically important but remain challenging for suppressing the non-desirable hydrogen evolution reaction (HER). Here, a Mn-doped Co(OH) (named as Mn-Co(OH) ) has been synthesized by in situ reconstruction in the electrolyte, which is able to dissociate H O molecules but inhibits the binding of H* species between each other owing to the increased interatomic spacing by the Mn-doping. The Mn-Co(OH) electrocatalyst offers a faradaic efficiency (FE) of as high as 98.

Hollow mesoporous carbon supported Co-modified Cu/CuO electrocatalyst for nitrate reduction reaction.

The electroreduction of nitrate (NO) pollutants to ammonia (NH) provides a sustainable approach for both wastewater treatment and NH synthesis. However, electroreduction of nitrate requires multi-step electron and proton transfer, resulting in a sluggish reaction rate. Herein, we synthesized a Co-modified Cu/CuO catalyst supported on hollow mesoporous carbon substrates (Co/Cu/CuO-MesoC) by a one-step microwave-assisted reduction method.

[Effect of weight growth velocity in the early stage after birth on neurodevelopment of preterm infants at the corrected age of 12 months].

Objective: To study the effect of weight growth velocity in the early stage after birth on the neurodevelopment of preterm infants at the corrected age of 12 months.

Methods: Related data were collected from the preterm infants who were discharged from the Department of Neonatology, Third Affiliated Hospital of Guangzhou Medical University, from July 1, 2015 to December 31, 2019 and were followed up at the outpatient service of high-risk infants. According to the weight growth velocity from birth to the corrected gestational age of 40 weeks, the infants were divided into two groups: low velocity [< 10 g/(kg·d); =21] and high velocity [≥10 g/(kg·d); =87].

[A clinical analysis of neurobehavioral development within one year after birth in preterm infants with bronchopulmonary dysplasia].

Objective: To study the effect of bronchopulmonary dysplasia (BPD) on neurobehavioral development within one year after birth in preterm infants.

Methods: A retrospective analysis was performed for the preterm infants with a gestational age of <34 weeks who were born from September 2017 to December 2019 and completed the follow-up assessments of neurobehavioral development at the corrected gestational ages of 40 weeks and 3, 6, and 12 months. According to their diagnosis, they were divided into a BPD group with 23 infants and a non-BPD group with 27 infants.

Lithocholic acid activates mTOR signaling inducing endoplasmic reticulum stress in placenta during intrahepatic cholestasis of pregnancy.

Aims: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific disorder, which increases risks of adverse fetal outcomes. However, the pathophysiology is not fully understood. Here, we explored the roles of mTOR signaling and ER stress in placenta during ICP.

Effect of parental physiological conditions and assisted reproductive technologies on the pregnancy and birth outcomes in infertile patients.

Assisted reproductive technologies (ART) are widely used to treat infertility. Emerging evidence suggested that ART was associated with perinatal or neonatal problems, however, little is known about the ART related risk factors. Here using 21136 ART cases, we determined the impacts of parental physiological conditions in the ART mediated pregnancy outcomes.

Objective: To establish a method for content determination of indirubin and indigo in Baphicacanthus cusia (Nees) Bremek.

Method: HPLC was used with C18 column, methanol-water (75:25) as mobile phase and detecting wavelength 289 nm.

Results: The range linear curve was 3.
