[Prenatal screening and diagnosis for a fetus with mosaic sex chromosome abnormality].

Objective: To carry out prenatal screening and diagnosis for a woman with advanced maternal age.

Methods: Non-invasive prenatal testing (NIPT) was carried out to determine the risk of fetal chromosome aneuploidy. Aminiocentesis was proceeded for fetal chromosomal karyotyping and copy number variation sequencing (CNV-seq).

Mitochondrial DNA methylation drift and postoperative delirium in mice.

Background: Mitochondrial dysfunction is linked to the etiopathogenesis of postoperative delirium (POD), which severely affects the prognosis of elderly patients undergoing surgery. The methylation of mitochondrial DNA (mtDNA), a new and incompletely described phenomenon that regulates the structure and function of mitochondria, is associated with ageing. However, the relationship between mtDNA methylation and POD has not been established.

Water Stable Heterometallic Zn-Tb Coordination Polymer for Rapid Detection of the Ultraviolet Filter Benzophenone.

Benzophenone (BP) is an ultraviolet filter (UVF) widely used in personal care products such as sunscreens and cosmetics. Excessive exposure to BP-type UVFs is a potential threat to human's health because of their endocrine-disrupting activity. Water stability of lanthanide compounds is crucial when they serve as luminescent sensors because of the practicality and recyclability.

Reversible structural transformation induced switchable single-molecule magnet behavior in lanthanide metal-organic frameworks.

Switchable "on/off" single-molecule magnet (SMM) behavior can be realized in lanthanide metal-organic frameworks (Ln-MOFs) tuned by the temperature-induced change of the coordination geometry of the lanthanide centers.
