Article Synopsis
- A study involving 52,047 pregnant women from 2012 to 2016 sought to investigate the link between high uterine artery pulsatility index (UtA-PI) values and the risk of congenital heart disease (CHD), looking at differences between singleton and multiple pregnancies.
- The research found that high right UtA-PI values were significantly associated with increased risks of maternal preeclampsia and, to a lesser extent, fetal CHD, especially in singleton pregnancies.
- Results indicated that preeclampsia mediated a significant portion of the CHD risk in singleton pregnancies, while high UtA-PI played a critical role in multiple pregnancies, highlighting the need for further research due to potential follow-up issues.
Objective: To quantify fetal cardiovascular parameters utilizing fetal-specific 2D speckle tracking technique and to explore the differences in size and systolic function of the left and right ventricles in low-risk pregnancy.
Methods: A prospective cohort study was performed in 453 low-risk single fetuses (28-39 weeks) to evaluate ventricular size [i.e.
Decreasing the cost associated with platinum-based catalysts along with improving their catalytic properties is a major challenge for commercial direct methanol fuel cells. In this work, a simple and facile strategy was developed for the more efficient preparation of multi-walled carbon nanotube (MWCNT) -supported Pt/CoPt composite nanoparticles (NPs) via solution plasma sputtering with subsequent thermal annealing. Quite different from general wet synthesis methods, Pt/CoPt composite NPs were directly derived from metal wire electrodes without any additions.

Objective: To explore the role and potential mechanism of human α-defensin 1 (HNP-1) on low-density lipoprotein (LDL) oxidation ability of human endothelial cells (EVC304).
Methods: Post incubation with LDL for 3 h, the malondialdehyde (MDA) and protein carbonyl (PCO) were detected in untreated ECV304 (control) and in HNP-1 transfected ECV304 in the presence and absence of siRNA against HNP-1. Flow cytometry and fluorescence microscopy were used to detect the generation of oxygen free radical in the ECV304 which have been pretreated by LDL, LPS and HNP-1, respectively.
