High anti-Müllerian hormone level as a predictor of poor pregnancy outcomes in women with polycystic ovary syndrome undergoing in vitro fertilization/intracytoplasmic sperm injection: a retrospective cohort study.

Objective: To study the correlation between anti-Müllerian hormone levels and pregnancy outcomes after in vitro fertilization/intracytoplasmic sperm injection in women with polycystic ovary syndrome, which remains controversial.

Methods: This retrospective cohort study recruited 4,719 women with infertility and polycystic ovary syndrome aged 20-40 years who underwent treatment at the Reproductive Center of Peking University Third Hospital between February 2017 and June 2023. We divided the participants into three groups according to the 25th and 75th percentile cutoffs of serum anti-Müllerian hormone: low (≤ 4.

In situ generation of Copper sulfide within Poly(lactic-co-glycolic acid): A strategy for Safer photothermal therapy in Triple-Negative breast cancer.

Copper sulfide nanoparticles (CuS NPs) have garnered significant attention in photothermal therapy (PTT) owing to their facile synthesis, biodegradability, stability, and excellent photothermal conversion efficiency. Nonetheless, their potential toxic effects have restricted their application. This research focuses on the encapsulation of CuS NPs with the biocompatible polymer poly(lactic-co-glycolic acid) (PLGA) to enhance their biocompatibility, thereby improving the efficacy and safety of PTT in the treatment of triple-negative breast cancer (TNBC).

Integrative analysis of cuproptosis-related lncRNAs: Unveiling prognostic significance, immune microenvironment, and copper-induced mechanisms in prostate cancer.

Background: Long non-coding ribonucleic acids (lncRNAs) regulate messenger RNA (mRNA) expression and influence cancer development and progression. Cuproptosis, a newly discovered form of cell death, plays an important role in cancer. Nonetheless, additional research investigating the association between cuproptosis-related lncRNAs and prostate cancer (PCa) prognosis is required.

Nonnegligible cascading impacts of global urban expansion on net primary productivity.

Accelerated global urban expansion not only directly occupies surrounding ecosystems, but also induces cascading losses of natural vegetation elsewhere through cropland displacement. Yet, how such effects alter the net primary productivity (NPP) worldwide remains unclear. Here, we quantified the direct and cascading impacts of global urban expansion on terrestrial NPP from 1992 to 2020 and projected the impacts under the shared socioeconomic pathways framework by 2100.

Decoding airway granulogenesis in children: unveiling risk factors for tracheobronchial foreign body aspiration and complications.

Background: Exogenous foreign body aspiration is a common high-risk condition in children. In a few cases, foreign body aspiration can lead to airway granulomas that interfere with tracheoscopic foreign body removal and threaten the life of the child.

Methods: This study was a retrospective analysis of the clinical data of 184 pediatric patients who were admitted to Quanzhou Children's Hospital from 2018 to 2021 with exogenous tracheobronchial foreign bodies.
