Association between heavy metal exposures and the prevalence of pelvic inflammatory disease: a cross-sectional study from the National Health and Nutrition Examination Survey 2013-2018.

Pelvic inflammatory disease (PID) is a common medical condition in women. However, the correlation between exposure to heavy metals, including cadmium (Cd), lead (Pb), manganese (Mn), mercury (Hg), and selenium (Se), and PID, is unclear. Using a large sample size from the National Health and Nutrition Examination Survey, these relationships were studied and verified.

Glioma-Associated Oncogene Family Zinc Finger 2 (GLI2) Activates Wnt Signaling through Transcriptional Inhibition of Neuronal Precursor Cell-Expressed Developmentally Downregulated 4 (NEDD4L) to Promote Androgen-Induced Granulosa Cell Damage.

Objective: Being a prevalent endocrine and metabolic disease, polycystic ovary syndrome (PCOS) severely threatens women's physical and mental health. Glioma-associated oncogene family zinc finger 2 (GLI2) expression is up-regulated in granulosa cells of PCOS patients, but its specific role in PCOS remains unclear.

Methods: Following the treatment of human ovarian granulosa cells (KGN) with dihydrotestosterone (DHT), RT-qPCR and western blot were utilized to check GLI2 expression.

Synthesis and sonocatalytic property of rod-shape Sr(OH)2·8H2O.

A novel rod-shape sonocatalyst Sr(OH)2·8H2O was prepared by a facile precipitation method, and characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and UV-vis absorption spectroscopy. Comparative sonocatalytic degradation experiments were carried out in different conditions under ultrasonic irradiation by using rhodamine B (RhB) as the model substrate, indicating that Sr(OH)2·8H2O was highly sonocatalytic. Total organic carbon experiment demonstrated Sr(OH)2·8H2O with mass mineralization of organic carbon.

Fabrication and sonocatalytic property of AgPO3 microsphere.

AgPO3 microspheres were prepared by a simple hydrothermal method. The AgPO3 microspheres were characterized by X-ray powder diffraction (XRD), scanning electronic microscopy (SEM), Brunauer-Emmett-Teller (BET), UV-vis absorption spectroscopy (UV-vis), and photoluminescence (PL) measurement. SEM reveals that the AgPO3 microspheres were constructed by the accumulation of small particles.
