Article Synopsis
  • Endohedral fullerenes are molecules that can encapsulate metal clusters, and this study introduces a new type called fluoride clusterfullerenes (FCFs).
  • The researchers successfully synthesized FCFs using various actinides, rare earth metals, and alkaline earth metals without needing extra modifications, revealing that adding a fluorine atom alters the metal-metal bonding significantly.
  • Their findings indicate that compounds like ThF@(7)-C and CaScF@(6)-C exhibit unique bonding interactions and promising magnetic properties, showcasing the potential of FCFs in future applications.

Metal-metal bonding is crucial in chemistry for advancing our understanding of the fundamental aspects of chemical bonds. Metal-metal bonds based on alkaline-earth (Ae) elements, especially the heavier Ae elements (Ca, Sr, and Ba), are rarely reported due to their high electropositivity. Herein, we report two heteronuclear di-EMFs CaY@(6)-C and CaY@(5)-C, which contain unprecedented single-electron Ca-Y metal-metal bonds.

Background: Whether the in vitro fertilization (IVF) has an effect on the cardiac function of the fetus is very important to evaluate the safety of the technique. The aim of this paper is to establish normal reference range for the fetal right myocardial performance index (RMPI), and compare the reference range between IVF fetuses and spontaneous pregnancy (SP) fetuses by automatic measurement of the RMPI.

Methods: Three hundred seventy-one spontaneous singleton pregnancies (the control group) and 39 singleton pregnancies conceived by IVF (the experimental group) were enrolled into the current study.

Aims: Excessive placental invasion is a life-threatening obstetric disease. Determining the extent of placental villi invasion prenatally is crucial for formulating a surgical plan for pregnant women. The objective of this study was to explore the diagnostic accuracy of the Crystal Vue technique combined with two-dimensional (2D) ultrasound in detecting the degree of placenta accreta spectrum (PAS) located in the C-section scar area.

Objective: This prospective study aimed to investigate the use of real-time three-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy), using contrast agent SonoVue, with B mode hysterosalpingo-contrast sonography (B mode-HyCoSy), to evaluate tubal patency and the wall of the Fallopian tubes in infertility patients.

Method: In total, we recruited 739 women with fertility requirements from the First Affiliated Hospital of Shantou Medical College between January 2017 and July 2018. All cases received 4D-HyCoSy using contrast agent SonoVue, immediately followed by the B mode-HyCoSy.
