Latent class analysis of loneliness and the influencing factors among school-age children: A cross-sectional survey.

Background: Children's loneliness has become an increasingly pervasive issue of public health due to the vulnerability of school-aged children. This study aims to identify latent classes of school-age children based on their exhibited symptoms of loneliness and explore the influencing factors.

Methods: A cross-sectional study was conducted from March to June 2023 in Shantou, China.

Association between heavy metals exposure and risk of attention deficit hyperactivity disorder (ADHD) in children: a systematic review and meta-analysis.

Heavy metals can negatively affect children's neurodevelopment, yet the relationship between heavy metals exposure and attention deficit hyperactivity disorder (ADHD) in children remains unclear. We aimed to examine associations between exposure to five common heavy metals (lead, arsenic, mercury, cadmium, and manganese) with neurodevelopmental toxicity and the risk of ADHD in children. Online databases of PubMed, Web of Science, and Embase were searched before February 29, 2024.

Association between parenting styles and dyslexia in primary school students: the mediating role of home literacy environment.

Background: Despite an increasing amount of research on the relationship between parenting styles and neurodevelopmental disorders, there has been minimal focus on how parenting styles impact children's reading abilities. The aim of this study was to investigate the potential mediating role of the home literacy environment in the connection between parenting styles and dyslexia.

Methods: A total of 212 primary school students from grade 2-5 were recruited for this study.

An Improved Orthogonal Matching Pursuit Algorithm for CS-Based Channel Estimation.

Wireless broadband transmission channels usually have time-domain-sparse properties, and the reconstruction of these channels using a greedy search-based orthogonal matching pursuit (OMP) algorithm can effectively improve channel estimation performance while decreasing the length of the reference signal. In this research, the improved OMP and SOMP algorithms for compressed-sensing (CS)-based channel estimation are proposed for single-carrier frequency domain equalization (SC-FDE) systems, which, in comparison with conventional algorithms, calculate the path gain after obtaining the path delay and updating the observation matrices. The reliability of the communication system is further enhanced because the channel path gain is calculated using longer observation vectors, which lowers the Cramér-Rao lower bound (CRLB) and results in better channel estimation performance.

Genome-wide identification and expression analysis of WRKY family genes under soft rot in Chinese cabbage.

Complex transcriptional networks regulate plant defense against pathogen attack, and plant transcription factors act as key regulators of the plant immune responses. The differences between transcription factor expression and regulation in Chinese cabbage soft rot (; Pc) have not been revealed. In this study, a total of 148 putative Chinese cabbage WRKY genes (BrWRKYs) were identified from the Chinese cabbage genome (v3.

Boosting the Iodine Adsorption and Radioresistance of Th-UiO-66 MOFs via Aromatic Substitution.

Effective capture of radioactive iodine is of paramount importance for the safe and long-term storage of fission products in the nuclear fuel cycle. Herein, a series of functionalized Th-UiO-66 MOFs was employed as a model to investigate the effects of substituents on iodine adsorption in both solution and vapor states. Sorption studies revealed that the electro-donating amino group exhibits the most positive role on increasing the removal rate of iodine from cyclohexane and the uptake capacity of iodine vapor.

Clinical value of Naa10p and CEA levels in saliva and serum for diagnosis of oral squamous cell carcinoma.

Background: N-α-acetyltransferase 10 protein (Naa10p) is a potential prognostic biomarker that modulates the phenotypes of several cancer types. Carcinoembryonic antigen (CEA) is currently the most well-known biomarker for the detection of epithelial malignancies. Our objective was to evaluate the clinical value of Naa10p, CEA, and their combined detection for diagnosis of oral squamous cell carcinoma (OSCC).
