The influence of professional identity, job satisfaction, burnout on turnover intention among village public health service providers in China in the context of COVID-19: A cross-sectional study.

Background: In China, COVID-19 has undoubtedly posed a huge challenge to the capacity of rural public health services. Village public health service providers are responsible for reporting and dealing with infectious diseases and public health emergencies. However, the turnover of village public health service providers is gravely threatening the stability of rural primary health system step by step.

Ferromagnetism in Narrow Bands of Moiré Superlattices.

Many graphene moiré superlattices host narrow bands with nonzero valley Chern numbers. We provide analytical and numerical evidence for a robust spin and/or valley polarized insulator at total integer band filling in nearly flat bands of several different moiré materials. In the limit of a perfectly flat band, we present analytical arguments in favor of the ferromagnetic state substantiated by numerical calculations.

MicroRNA-410 is involved in mitophagy after cardiac ischemia/reperfusion injury by targeting high-mobility group box 1 protein.

Mitochondrial dysfunction has emerged as a critical pathophysiological factor of myocardial ischemia/reperfusion (I/R) injury. A thorough understanding of mitochondrial dysfunction during I/R at the molecular level is urgently needed. One prominent microRNA, miR-410, was previously reported to be dynamically regulated in diverse cardiomyopathies, but its mechanism is unclear.

Plasma Metabolic Profile Determination in Young ST-segment Elevation Myocardial Infarction Patients with Ischemia and Reperfusion: Ultra-performance Liquid Chromatography and Mass Spectrometry for Pathway Analysis.

Background: This study was to establish a disease differentiation model for ST-segment elevation myocardial infarction (STEMI) youth patients experiencing ischemia and reperfusion via ultra-performance liquid chromatography and mass spectrometry (UPLC/MS) platform, which searches for closely related characteristic metabolites and metabolic pathways to evaluate their predictive value in the prognosis after discharge.

Methods: Forty-seven consecutive STEMI patients (23 patients under 45 years of age, referred to here as "youth," and 24 "elderly" patients) and 48 healthy control group members (24 youth, 24 elderly) were registered prospectively. The youth patients were required to provide a second blood draw during a follow-up visit one year after morbidity (n = 22, one lost).

A 20-year follow-up study on the effects of long-term exposure to thorium dust.

Objective: To investigate the possible effects of long-term exposure to dust containing thorium and thoron progeny on dust-exposed miners.

Methods: A negative, high voltage, exhaled thoron progeny measurement system was used to estimate the miners' thorium lung burden.

Results: The highest thorium lung burden of 638 miners was 11.
