Effect of Consultation Number on the Assessment and Treatment of Polycystic Ovary Syndrome.

Background: The basic medical education stage is not enough to support physicians to fully diagnose and evaluate polycystic ovary syndrome (PCOS). The study aims to discover the difference in treatment choice between participants with different annual consultation number of PCOS, to promote lifelong learning, and drive balanced development within healthcare.

Methods: This is a multicenter cross-sectional survey.

A comprehensive evaluation of microplastic pollution in the Xiangshan Bay of China with special reference to seasonal variation.

Marine microplastic (MP) pollution has drawn global attention due to its potential risk to ecosystem. In the present study, we investigated MP pollution in surface water and sediment of a semi-closed bay: the Xiangshan Bay in the East China Sea in spring and summer. The results showed that MP abundance in surface water increased significantly in summer than spring (0.

The role of obstetrician-gynecologists and reproductive endocrinologists in the blood glucose management of polycystic ovary syndrome.

This study aimed to compare the differences between reproductive endocrinologists (Repro-Endo) and obstetricians-gynecologists (Ob-Gyn; non-reproductive medicine specialty) in diagnosing, evaluating, and treating PCOS women with insulin resistance (IR). Repro-Endo and Ob-Gyn in China participated in this survey, and their responses were analyzed using tests, Fisher exact tests, and multivariable logistic regression analysis. The study analyzed 2412 survey responses (92.

The Disparity in the Management of Polycystic Ovary Syndrome between Obstetrician-Gynecologists in Different-Level Hospitals under the Hierarchical Medical System.

Background: PCOS is a prevalent endocrine and metabolic disorder in women characterized by abnormal blood glucose, dyslipidemia, and abnormal mental health. To improve patient care, the goal of our study is to find out if there are differences in how PCOS patients are treated at different hospital levels within the hierarchical medical system.

Methods: Obstetricians and gynecologists from primary, secondary, and tertiary hospitals were the participants in the survey.

Melatonin Alleviates Copper Toxicity via Improving ROS Metabolism and Antioxidant Defense Response in Tomato Seedlings.

The excessive accumulation of copper (Cu) has become a threat to worldwide crop production. Recently, it was revealed that melatonin (MT) could play a crucial role against heavy metal (HM) stresses in plants. However, the underlying mechanism of MT function acted upon by Cu stress (CS) has not been substantiated in tomatoes.

Obesity management in polycystic ovary syndrome: disparity in knowledge between obstetrician-gynecologists and reproductive endocrinologists in China.

Background: Obesity is associated with the development of polycystic ovary syndrome (PCOS) and contributes substantially to metabolic abnormalities in women with PCOS. The study aimed to describe and compare the practices of physicians in the diagnosis, evaluation, and treatment of obesity in patients with PCOS.

Methods: Reproductive endocrinologists (Repro-Endo) and obstetrician-gynecologists (non-reproductive medicine specialty, OB-Gyn) in China participated in a survey, and their responses were analyzed using χ tests, Fisher exact tests, and multivariable logistic regression analysis.

Ethylene response factors 15 and 16 trigger jasmonate biosynthesis in tomato during herbivore resistance.

Jasmonates (JAs) are phytohormones with crucial roles in plant defense. Plants accumulate JAs in response to wounding or herbivore attack, but how JA biosynthesis is triggered remains poorly understood. Here we show that herbivory by cotton bollworm (Helicoverpa armigera) induced both ethylene (ET) and JA production in tomato (Solanum lycopersicum) leaves.

Sources and ecological risk assessment of PAHs in surface sediments from Bohai Sea and northern part of the Yellow Sea, China.

Sources and ecological risk of sixteen priority PAHs in surface sediments from Bohai Sea (BS) and northern part of the Yellow Sea (NPYS) were investigated. The total concentrations of PAHs varied in ranges 149.24-1211.
