Researchers from the Chinese People's Liberation Army have conducted a study on sleep disorders and the accuracy of sleep staging methods. The study found that sleep apnea disrupts the regularity of sleep stages, affecting the performance of sleep stage detection and influencing the accuracy of sleep staging. The researchers are working on developing sleep staging methods that can diminish the impact of sleep apnea and exhibit better generalization capabilities. The study also highlights the advantages of automated methods over manual scoring for sleep stage classification. [Extracted from the article]

Researchers at the Southern University of Science and Technology (SUSTech) in Shenzhen, China have developed a DNA biosensor platform for the detection of HIV. The platform utilizes a portable fluorescence detector and the activity of the HIV-encoded integrase enzyme as a biomarker for specific and quantitative detection of the virus. The biosensor system demonstrated high sensitivity and accuracy in detecting HIV in clinical samples, and it also showed potential for detecting other retroviruses. The researchers believe that this platform could be valuable for rapid HIV testing, diagnosis, and treatment monitoring, contributing to the development of effective prevention strategies and treatments.

Researchers from the Southern University of Science and Technology (SUSTech) in Shenzhen, China, have developed a novel detection assay for Klebsiella pneumoniae (K. pneumoniae) infection. The assay utilizes a DNA sensor system combined with Rolling Circle Amplification (RCA) technology to enable sensitive and specific identification of K. pneumoniae-encoded topoisomerase IV (K. pneumoniae Topo IV). The DNA sensor system demonstrated high sensitivity and accuracy in detecting K. pneumoniae from clinical samples, suggesting its potential application in clinical settings for detecting other pathogenic microbes as well. The research was funded by the Shenzhen Science and Technology Program, National Natural Science Foundation of Guangdong Province, and National Natural Science Foundation of China.
