Antenatal sleep quality associated with perinatal outcomes in women of advanced maternal age.

Objectives: The increasing prevalence of advanced maternal age (AMA) coupled with poor sleep quality among pregnant women makes it important to study their association with perinatal outcomes. However, little is known about the interaction of AMA and maternal antenatal sleep on perinatal outcomes. Here, we examined whether associations between AMA and perinatal outcomes are modified by antenatal sleep quality.

Ag-Deposited Electrospun SrTiO₃ Nanofiber with Enhanced Photocatalytic Activity for Degradation of Methylene Orange.

Perovskite SrTiO3 nanofibers were successfully fabricated using a facile electrospinning method followed by calcination in air. The structures, morphologies, and photocatalytic performance of the one-dimensional SrTiO3 nanofibers were determined through X-ray diffraction, UV-visible spectroscopy, scanning electron microscopy, and degradation of organic dye under light irradiation. The nanofibrous SrTiO3 exhibited enhanced photocatalytic activity after photodeposition of Ag on its surface to degrade methylene orange dye.
