Background: No prior study has examined the mutual association of long-term outdoor ozone (O) concentration and physical activity (PA) with emotional and behavioral problems (EBPs) in children and adolescents. This study aims to investigate the association between long-term outdoor O concentration and the risk of EBPs in children and adolescents and further explore whether increased PA levels modify this association.

Methods: Data were obtained from the 2020 wave follow-up examination of an ongoing prospective cohort study (COHERENCE project) in Guangzhou, China.

Background: The existing predictive models for metabolic-associated fatty liver disease (MAFLD) possess certain limitations that render them unsuitable for extensive population-wide screening. This study is founded upon population health examination data and employs a comparison of eight distinct machine learning (ML) algorithms to construct the optimal screening model for identifying high-risk individuals with MAFLD in China.

Methods: We collected physical examination data from 5,171,392 adults residing in the northwestern region of China, during the year 2021.

Background: Transfer RNA (tRNA)-derived small RNA (tsRNA) represents an important and increasingly valued type of small non-coding RNA (sncRNA). The investigation of tRNA and tsRNA modification crosswalks has not only provided novel insights into the information and functions of tsRNA, but has also expanded the diversity and complexity of the tsRNA biological regulation network.

Aim Of Review: Comparing with other sncRNAs, tsRNA biogenesis show obvious correlation with RNA modifications from mature tRNA and harbor various tRNA modifications.

Background: Circular RNAs (circRNAs) have been identified as playing an integral role in the development of bladder cancer (BC). However, the mechanism by which circRNAs operate in the chemical carcinogenesis of BC remains unclear.

Methods: To explore this mechanism, we used RNA high-throughput sequencing to identify differentially expressed circRNA in bladder epithelial cells and chemically induced malignant transformed BC cells.

Emerging evidence indicates that transfer RNA (tRNA)-derived small RNAs (tsRNAs), originated from tRNA with high abundance RNA modifications, play an important role in many complex physiological and pathological processes. However, the biological functions and regulatory mechanisms of modified tsRNAs in cancer remain poorly understood. Here, it is screened for and confirmed the presence of a novel mG-modified tsRNA, mG-3'-tiRNA Lys (mtiRL), in a variety of chemical carcinogenesis models by combining small RNA sequencing with an mG small RNA-modified chip.

Objective: Bladder cancer is one of the most prominent malignancies affecting the urinary tract, characterized by a poor prognosis. Our previous research has underscored the pivotal role of mA methylation in the progression of bladder cancer. Nevertheless, the precise relationship between N6-methyladenosine (mA) regulation of long non-coding RNA (lncRNA) and bladder cancer remains elusive.

Ambient air pollutants exposures may lead to aggravated Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD). However, there is still a scarcity of empirical studies that have rigorously estimated this association, especially in regions where air pollution is severe. To fill in the literature gap, we conducted a cross-sectional study involving 2711,207 adults living in five regions of southern Xinjiang Uyghur Autonomous Region in 2021.

3-Methylcholanthracene (3-MC) is one of the most carcinogenic polycyclic aromatic hydrocarbons (PAHs). Long-term exposure to PAHs has been thought of as an important factor in urothelial tumorigenesis. N-methyladenosine (mA) exists widely in eukaryotic organisms and regulates the expression level of specific genes by regulating mRNA stability, translation efficiency, and nuclear export efficiency.

Background: Limited evidence exists regarding the link between air pollution exposure and cognitive function in developing countries, particularly in areas with abundant natural sources of particulate matter.

Objectives: To investigate this association in a large representative sample of the elderly in northwestern China.

Methods: We performed a cross-sectional study among 176,345 participants aged 60-100 years in northwestern China in 2020.

Article Synopsis
  • This study looked at how bad air pollution can cause chronic bronchitis (CB) in people living in Northwestern China.
  • They checked air quality data from 2017 to 2019 and studied over 6.5 million adults to see how different pollutants affected their health.
  • The findings showed that more exposure to certain types of air pollution increased the chances of getting CB, especially in younger people and those with unhealthy habits like smoking and not exercising.

Of major concern is the lack of correlation between the material design and structural function of asphalt pavement in China. The objective of this paper is to identify the layer in asphalt pavement where permanent deformation occurs most seriously and to propose a control index for that layer's asphalt mixture. The permanent deformation of each layer was determined through the utilization of thickness measurements obtained from field cores.

Relation extraction is one of the important steps in building a knowledge graph. Its main objective is to extract semantic relationships from identified entity pairs in sentences, playing a crucial role in semantic understanding and knowledge graph construction. Remote supervised relation extraction aligns knowledge bases with natural language texts and generates labeled data, which alleviates the burden of manually annotating datasets.

The literature has established that the capability of visuomotor adaptation decreases with aging. However, the underlying mechanisms of this decline are yet to be fully understood. The current study addressed this issue by examining how aging affected visuomotor adaptation in a continuous manual tracking task with delayed visual feedback.

RNA modifications, including adenine methylation (mA) of mRNA and guanine methylation (mG) of tRNA, are crucial for the biological function of RNA. However, the mechanism underlying the translation of specific genes synergistically mediated by dual mA/mG RNA modifications in bladder cancer (BCa) remains unclear. We demonstrated that mA methyltransferase METTL3-mediated programmable mA modification of oncogene trophoblast cell surface protein 2 (TROP2) mRNA promoted its translation during malignant transformation of bladder epithelial cells.

Introduction: N6-methyladenosine (mA) modification contributes to the pathogenesis and development of various cancers, including bladder cancer (BCa). In particular, integrin α6 (ITGA6) promotes BCa progression by cooperatively regulating multisite mA modification. However, the therapeutic effect of targeting ITGA6 multisite mA modifications in BCa remains unknown.

(1) Background: Resilience research began in the child population as a validity scale to describe children's psychological wellbeing and ability to cope with negative events, and to some extent, to predict recovery and adaptation when they experience adversity again. In view of the important developmental implications of resilience in young children and the lack of a Chinese children's resilience scale, this study developed a resilience scale for young Chinese children based on a systematic review of existing international resilience scales and the characteristics of the Chinese cultural background. (2) Methods: The scale was developed by referring to existing scales, expert interviews, item collation and item finalization, developing original items, then deleting and determining items through item analysis, and finally, comparing with existing scales to obtain the internal and external validity of this scale.

Cross-domain few-shot learning is one of the research highlights in machine learning. The difficulty lies in the accuracy drop of cross-domain network learning on a single domain due to the differences between the domains. To alleviate the problem, according to the idea of contour cognition and the process of human recognition, we propose a few-shot learning method based on pseudo-Siamese convolution neural network.
