Triage performance of DNA methylation for women with high-risk human papillomavirus infection.

Objective: DNA methylation is a promising biomarker for cervical cancer screening. This study aimed to validate the triage performance of cytological DNA methylation for detecting cervical intraepithelial neoplasia of grade 3 or worse (CIN3+) in women with high-risk human papillomavirus (hrHPV) infection from a large prospective cohort undergoing opportunistic screening in China (METHY3).

Methods: The triage performance for detecting CIN3+ lesions was compared between HPV16/18 genotyping, a liquid-based cytology (LBC) test, and the PAX1 and JAM3 methylation (PAX1m/JAM3m) test according to cervical pathologic outcomes.

Development of a Simvastatin-Loaded Copolymer Acid-Sensitive Nanocarrier and Its Experimental Use in the Treatment of Keloids.

Objective: The lipid-lowering simvastatin (SIM) has been shown to be an effective inhibitor of keloid proliferation. However, due to its low water solubility and short half-life, simvastatin aggregates to the liver and does not reach the skin lesions after oral administration, which restricts its widespread clinical use. The development of nanomedicine provides the possibility for us to break through this bottleneck problem clinically.

Long-term plume-chasing measurements: Emission characteristics and spatial patterns of heavy-duty trucks in a megacity.

Assessing the emissions of heavy-duty diesel trucks (HDDTs) is crucial for managing air quality in megacities, especially concerning nitrogen oxides (NO) and black carbon (BC). This study employed mobile plume chasing to monitor the real-world emissions of over 7778 HDDTs in Shenzhen. The findings indicate that the real-world NO emission factors (EF) of China IV trucks did not differ significantly from those of China III, whereas China V and VI vehicles demonstrated fleet-averaged reductions of 27% and 85%, respectively.

Identification of the histone acetyltransferase gene family in the genome.

As the most effective therapeutic drug for malaria, artemisinin can only be extracted from L., which is sensitive to the surrounding growing habitat. Histone acetyltransferases (HATs) contain acetyl groups, which modulate mRNA transcription and thereby regulate plant environmental adaptation.

Characterization of on-road nitrogen oxides and black carbon emissions from high emitters of heavy-duty diesel vehicles in China.

Heavy-duty diesel vehicles (HDDVs) significantly contribute to atmospheric nitrogen oxides (NO) and black carbon (BC), with high emitters within the HDDV fleet impacting the total emissions. However, emission patterns and contributions of high emitters are rarely explored from a fleet-perspective. We investigated NO and BC emission factors (EFs) from 1925 HDDVs in Shenzhen by the plume-chasing method, and found that the fleet-average EFs decreased with stricter emission standards.
