Dynamic characteristics of high-risk HPV infection in women with low-grade cervical intraepithelial neoplasia, based on a community longitudinal study.

Background: High-risk human papillomavirus (HR-HPV) infection is the primary cause of cervical cancer and precancerous lesions. Approximately 35% of women with low-grade cervical intraepithelial neoplasia (CIN1) may experience persistence or progression to high-grade lesions. Yet, the dynamic characteristics of HR-HPV infection in women with CIN1 remain unclear.

A near-infrared multifunctional fluorescent bio-probe with large stokes shift and high quantum yield for effective determination of heavy metal lead and pesticide glyphosate in vitro and vivo.

Heavy metal contamination and pesticide residues pose significant threats to human health and ecosystems. Despite its broad applications, fluorescence imaging technology often struggles in complex ecological and biological environments due to disadvantages of background autofluorescence and low quantum yield. This study introduced a near-infrared (NIR) multifunctional "off-on-off" isophorone-based fluorescent bio-probe, DHB, characterized by a high fluorescence quantum yield (10.

Hepatitis B virus hijacks MRE11-RAD50-NBS1 complex to form its minichromosome.

Chronic hepatitis B virus (HBV) infection can significantly increase the incidence of cirrhosis and liver cancer, and there is no curative treatment. The persistence of HBV covalently closed circular DNA (cccDNA) is the major obstacle of antiviral treatments. cccDNA is formed through repairing viral partially double-stranded relaxed circular DNA (rcDNA) by varies host factors.

Relationship between middle school students' academic stress and physical exercise behavior from the perspective of Self-Determination Theory: The chained mediation of motivation and intention.

Academic stress is associated with lower engagement in healthy behaviors, including physical exercise, among middle school students. Based on Self-Determination Theory, this study examines the association between academic stress and physical exercise behavior among middle school students, exploring the mechanisms through the chained mediation of motivation and intention. Scales used in this study include the Academic Stress Scale, Autonomous and Controlled Motivation Scales, and Physical Exercise Intention and Behavior Scales to measure relevant variables.

Clinical Manifestations.

Background: The intricate and heterogeneous phenotypes associated with neuropsychiatric symptoms (NPSs) encumber exploration of their role in the neuropathology and underlying biological mechanisms of Alzheimer's disease (AD) continuum.

Method: An individual-level Regional Radiomics Similarity Network (R2SN) for 487 patients with AD continuum (376 with NPSs vs. 111 without NPSs) were developed to find the R2SN connections associated with NPSs and refine the subtypes of NPS in the AD continuum.
