Closer adult child-parent relations the stronger the vaccine hesitancy: A cross-sectional study of adult Children's attitudes toward pneumococcal vaccination of elderly parents and its determinants in Guangzhou, China.

Pneumococcal disease (PD) has a serious effect on older people aged 60 years and above. However, pneumococcal vaccination rates for older people in China remain low. This study aimed to explore adult children's perspectives on the vaccination of their parents and to examine the determinants of vaccine hesitancy.

Mechanisms involved in the regulation of mitochondrial quality control by PGAM5 in heart failure.

Heart failure (HF) refers to a group of clinical syndromes in which various heart diseases lead to the inability of cardiac output to meet the metabolic needs of the body's tissues. Cardiac metabolism requires enormous amounts of energy; thus, impaired myocardial energy metabolism is considered a key factor in the occurrence and development of HF. Mitochondria serve as the primary energy source for cardiomyocytes, and their regular functionality underpins healthy cardiac function.

Exploring T7 RNA polymerase-assisted CRISPR/Cas13a amplification for the detection of BNP via electrochemiluminescence sensing platform.

Brain natriuretic peptide (BNP) is considered to be an important biomarker of heart failure (HF) attracting attention. However, its low concentration and short half-life in blood lead to a low-sensitivity detection of BNP, which is a challenge that has to be overcome. In this work, we propose a highly specific, highly sensitive T7 RNA polymerase-assisted clustered regularly interspaced short palindromic repeats (CRISPR)/Cas13a system to detect BNP via an electrochemiluminescence (ECL) sensing platform and incorporate exonuclease III (Exo III)-hairpin and dumbbell-shaped hybridization chain reaction (HCR) technologies.

Evaluation of Chlamydia trachomatis screening from the perspective of health economics: a systematic review.

Background: Most Chlamydia trachomatis (CT) infections are asymptomatic. The infection can persist and lead to severe sequelae. Therefore, screening for CT can primarily prevent serious sequelae.

Challenges of epidemiological investigation work in the COVID-19 pandemic: a qualitative study of the epidemiology workforce in Guangdong Province, China.

Objectives: This study sought to identify the epidemiological investigation challenges of the COVID-19 pandemic and offer insights into the underlying issues.

Design: An exploratory qualitative study used thematic analysis of semistructured and in-depth individual interviews.

Setting: This study was conducted in Centers for Disease Control and Prevention in Guangdong Province.

Fluid Shear Stress Ameliorates Prehypertension-Associated Decline in Endothelium-Reparative Potential of Early Endothelial Progenitor Cells.

This study investigated the effects of prehypertension and shear stress on the reendothelialization potential of human early EPCs and explored its potential mechanisms. Early EPCs from the prehypertensive patients showed reduced migration and adhesion in vitro and demonstrated a significantly impaired in vivo reendothelialization capacity. Shear stress pretreatment markedly promoted the in vivo reendothelialization capacity of EPCs.

Integrated Strategies of Diverse Feature Selection Methods Identify Aging-Based Reliable Gene Signatures for Ischemic Cardiomyopathy.

Ischemic cardiomyopathy (ICM) is a major cardiovascular state associated with prominently increased morbidity and mortality. Our purpose was to detect reliable gene signatures for ICM through integrated feature selection strategies. Transcriptome profiles of ICM were curated from the GEO project.

Downregulation of Uncoupling Protein 2(UCP2) Mediated by MicroRNA-762 Confers Cardioprotection and Participates in the Regulation of Dynamic Mitochondrial Homeostasis of Dynamin Related Protein1 (DRP1) After Myocardial Infarction in Mice.

Acute myocardial infarction (MI) is one of the leading causes of death in the world, and its pathophysiological mechanisms have not been fully elucidated. The purpose of this study was to investigate the role and mechanism of uncoupling protein 2 (UCP2) after MI in mouse heart. Here, we examined the expression and role of UCP2 in mouse heart 4 weeks after MI.

LncRNA PVT1 Knockdown Ameliorates Myocardial Ischemia Reperfusion Damage via Suppressing Gasdermin D-Mediated Pyroptosis in Cardiomyocytes.

Myocardial ischemia reperfusion (I/R) damage is a life-threatening vascular emergency after myocardial infarction. Here, we observed the cardioprotective effect of long non-coding RNA (lncRNA) PVT1 knockdown against myocardial I/R damage. This study constructed a myocardial I/R-induced mouse model and a hypoxia/reoxygenation (H/R)-treated H9C2 cells.

Bisphenol Analogues and Their Chlorinated Derivatives in Breast Milk in China: Occurrence and Exposure Assessment.

Concentrations of bisphenol A (BPA) and its analogues (together with their chlorinated derivatives are referred to as BPs) were measured in 181 breastmilk samples collected from 9 provinces in China in 2014. Twelve BP types were found. The BP concentrations ranged from not detected to 5.

[Association between hemoglobin scavenger receptor CD163 expression and coronary atherosclerotic severity in patients with coronary heart disease].

Objective: To investigate the association between hemoglobin scavenger receptor (CD163) expression levels on monocytic surfaces and coronary atherosclerotic severity in patients with coronary heart disease (CHD) as well as the roles of CD163 in inflammation and lipidperoxidation.

Methods: Eighty-four patients were diagnosed as CHD according to the results of coronary angiography and ACC/AHA diagnostic criteria. The patients were divided into 3 groups: acute myocardial infarction (AMI) group (n = 30), unstable angina (UA) group (n = 30), stable angina (SA) group (n = 24).
