Bioanalysis based on optical imaging has gained significant progress in the last few decades. Luminescence probes are capable of detecting, monitoring, and tracing particular biomolecules in complex biological systems to figure out the roles of these molecules in organisms. Considering the rapid development of luminescence probes for bio-applications and their promising future, we have attempted to explore the working principles and recent advances in bio-applications of luminescence probes, in the hope of helping readers gain a detailed understanding of luminescence probes developed in recent years.

Objective: This study is intended to examine the efficacy of a non-irrigated bipolar RF clamp and explore the factors that can influence its performance on beating human hearts using the electrophysiology mapping method.

Methods: A total of 83 atrial fibrillation (AF) patients were included in this study. Based on the Body mass index (BMI, kg/m), the AF patients were divided into the normal group (18.

Background: Obesity is a crucial risk factor for obstructive sleep apnea (OSA), but the association between adiposity deposition and OSA risk has not reached a consistent conclusion. This study sought to reveal the association of multiple adiposity indicators with OSA risk.

Methods: This cross-sectional study included 9,733 participants aged 35-74 years, recruited from an ongoing population-based cohort.

Background: Investigating adherence to the Atrial Fibrillation Better Care (ABC) pathway management and identifying gaps between the real world and established guidelines can lead to better integrated management of AF. Current data on adherence to ABC pathway management among community elderly patients with atrial fibrillation (AF) in Chinese communities is limited.

Aim: To investigate the adherence to ABC pathway management among community elderly patients with AF in China.

Article Synopsis
  • Heart failure is a significant global health concern, with a comprehensive study revealing trends and contributing factors from 1990 to 2019.
  • In 2019, the age-standardized prevalence of heart failure was approximately 711.90 cases per 100,000 population, showing a general decline overall, though an increase was noted between 2017 and 2019, especially in less-developed countries.
  • Ischemic and hypertensive heart diseases are the leading causes of heart failure, highlighting the need for targeted prevention and treatment efforts in these regions.

Atrial fibrillation (AF) is the most common tachyarrhythmia in the world. Lung cancer is the leading cause of cancer deaths in 93 countries. Previous studies demonstrated that the prevalence of AF was higher in patients with lung cancer.

Objectives: This study aimed to investigate the potential factors associated with adherence to colonoscopy among participants who were preliminarily screened positive in a community-based colorectal cancer screening program in China.

Methods: This study analyzed data from 1219 out of 6971 community residents who were identified as positive cases by the well-validated high-risk factor questionnaire (HRFQ) or fecal immunochemical test (FIT) in the preliminary screening stage for colorectal neoplasms. Patients showing adherence to colonoscopy were defined as those who received positive results in a preliminary screening for colorectal neoplasms and later received a colonoscopy examination as required.

Background: Several works of observational clinical research indicate that coronary artery disease (CAD) and atrial fibrillation (AF) aggravate each other. However, it is unknown whether these associations reveal independent causal processes. Objective: The present study aimed to evaluate causal associations between CAD and AF using two-sample Mendelian randomization (TSMR) analysis.

Background: Observational studies on the association between neuroticism and coronary artery disease (CAD) are still rare, and the results of existing studies are not consistent. The present study aimed to explore causal associations of neuroticism with CAD.

Methods: The summary-level data of GWAS for neuroticism and 12 items used to assess neuroticism were extracted from the UK Biobank, and included up to 380,506 participants.

Background: The positive predictive value (PPV) of high risk factor questionnaire (HRFQ) plus fecal immunochemical test (FIT) as preliminary screening strategy for colorectal-related neoplasia is relatively low. We aim to explore independent factors associated with PPVs of HRFQ combined FIT for selecting high risk individuals for colonoscopy.

Methods: A total of 6971 residents were enrolled in a community-based screening program.

Objective: The effect of dietary factors on OSA remains unclear. This study was to investigate the association of obstructive sleep apnea (OSA) with individual and overall effects of eating habits among adult Chinese.

Methods: A total of 9733 participants were selected from the baseline survey of the Guangzhou Heart Study.

Objectives: To investigate the clinical validity of using a handheld fundus camera to detect diabetic retinopathy (DR) in China.

Design And Settings: Prospective comparison study of the handheld fundus camera with a standard validated instrument in detection of DR in hospital and a community screening clinic in Guangdong Province, China.

Participants: Participants aged 18 years and over with diabetes who were able to provide informed consent and agreed to attend the dilated eye examination with handheld tests and a standard desktop camera.

Motivation: DNA replication is the key of the genetic information transmission, and it is initiated from the replication origins. Identifying the replication origins is crucial for understanding the mechanism of DNA replication. Although several discriminative computational predictors were proposed to identify DNA replication origins of yeast species, they could only be used to identify very tiny parts (250 or 300 bp) of the replication origins.

Aim: The present study aims at preparation of CARP antibody and analysis of CARP expression pattern.

Methods: Through bioinformatics analysis the antigenicity of CARP, 279 bp cDNA fragment coding CARP N-terminal 93 amino acid was amplified by RT-PCR from mouse heart RNA, then cloned into pET-28b to construct the prokaryotic expression pET 28b-CARP N93. The plasmid was transformed into E.

Bayesian spatial risk profiling holds promise to enhance our understanding of the epidemiology of parasitic diseases, and to target interventions in a cost-effective manner. Here, we present findings from a study using Bayesian variogram models to map and predict the seroprevalence of Schistosoma japonicum in Eryuan county, Yunnan province, China, including risk factor analysis. Questionnaire and serological data were obtained through a cross-sectional survey carried out in 35 randomly selected villages with 3,220 people enrolled.

Whilst infections with soil-transmitted helminths are common across China, the public-health significance of Schistosoma japonicum and food-borne helminths is more focalized. Only few studies have investigated the local epidemiology of helminth infections in rural China, including risk factor analysis. We collected stool and blood samples from 3220 individuals, aged 5-88 years, from 35 randomly selected villages in Eryuan county, Yunnan province, China.
