Association of ambient air pollutant mixtures with IVF/ICSI-ET clinical pregnancy rates during critical exposure periods.

Study Question: Does exposure to a mixture of ambient air pollutants during specific exposure periods influence clinical pregnancy rates in women undergoing IVF/ICSI-embryo transfer (ET) cycles?

Summary Answer: The specific exposure period from ET to the serum hCG test was identified as a critical exposure window as exposure to sulfur dioxide (SO) or a combination of air pollutants was associated with a decreased likelihood of clinical pregnancy.

What Is Known Already: Exposure to a single pollutant may impact pregnancy outcomes in women undergoing ART. However, in daily life, individuals often encounter mixed pollution, and limited research exists on the effects of mixed air pollutants and the specific exposure periods.

The downregulation of SASH1 expression promotes breast cancer occurrence and invasion accompanied by the activation of PI3K-Akt-mTOR signaling pathway.

SASH1 (SAM and SH3 domain containing 1) has been increasingly reported as a tumor suppressor gene. However, there is limited research on the role of SASH1 in breast cancer. This manuscript aims to investigate the mechanism of SASH1 in the occurrence, development, and prognosis of breast cancer.

Lung ultrasound diagnosis of pulmonary edema resulting from excessive fluid absorption during hysteroscopic myomectomy: a case report.

Case Presentation: In this case report, we present a unique instance where lung ultrasound was utilized to diagnose pulmonary edema in a patient following a hysteroscopic myomectomy procedure.

Framework nucleic Acid-MicroRNA mediated hepatic differentiation and functional hepatic spheroid development for treating acute liver failure.

The specific induction of hepatic differentiation presents a significant challenge in developing alternative liver cell sources and viable strategies for clinical therapy of acute liver failure (ALF). The past decade has witnessed the blossom of microRNAs in regenerative medicine. Herein, microRNA 122-functionalized tetrahedral framework nucleic acid (FNA-miR-122) has emerged as an unprecedented and potential platform for directing the hepatic differentiation of adipose-derived mesenchymal stem cells (ADMSCs), which offers a straightforward and cost-effective method for generating functional hepatocyte-like cells (FNA-miR-122-iHep).

Mental health concerns during pregnancy associated with the risk of preterm birth: A retrospective cohort study.

Backgrounds: There are multiple risk factors for preterm birth (PTB), one of the most important of which is mood disorders during pregnancy. We aimed to comprehensively investigate the association of both total mental health concerns and ten specific psychiatric symptoms with PTB risk.

Methods: A cohort study was performed consisting of 25,175 pregnant women who participated in Women and Children's Hospital of Chongqing Medical University between 2020 and 2022.
