Predicting the risk of high-grade precancerous cervical lesions based on high-risk HPV typing in Changsha China.

Background: Persistent infection with high-risk human papillomavirus (HPV) is a significant risk factor for cervical cancer. HPV typing and cytology are conducted in women of appropriate age to assess the risk of cervical lesions and to guide the need for further diagnostic procedures such as colposcopy, cervical biopsy, or treatment. This article explores methods to predict the risks of high-grade precancerous cervical lesions based on high-risk HPV typing.

CRISPR knock-in of a chimeric antigen receptor into GAPDH 3'UTR locus generates potent B7H3-specific NK-92MI cells.

CAR-NK therapy is becoming a promising approach to treat solid tumors. However, the random insertion of the CAR gene and inflexible CAR expression caused by common preparation methods significantly impact its efficacy and safety. Here we successfully established a novel type of CAR-NK cells by integrating CAR sequences into the GAPDH 3'UTR locus of NK-92MI cells (CRISPR-CAR-NK), achieving site-specific integration of the CAR gene and allowing endogenous regulatory components to govern CAR expression.

Nonylphenol promotes epithelial-mesenchymal transition in colorectal cancer cells by upregulating miR-151a-3p.

Nonylphenol (NP) is a common environmental contaminant and endocrine disruptor. Our previous research demonstrated that NP could promote the proliferation and epithelial-mesenchymal transition (EMT) of colorectal cancer (CRC) cells; however, the specific mechanism remains unclear. miRNA sequencing revealed that NP upregulated the expression levels of microRNA(miR)-151a-3p in CRC.

Highly Efficient Degradation of Bisphenol A by Peroxymonosulfate Activation Using Bamboo Kraft Lignin Single-Atom Catalyst.

A nitrogen-coordinated Fe single-atom catalyst (SA Fe-N/C) is synthesized using a homogeneous ethanol-based dissolution system with bamboo kraft lignin serving as the carbon source. Uniformly dispersed Fe atoms with an interatomic distance of less than 2 Å throughout the SA Fe-N/C structure are revealed through X-ray absorption spectral analysis and HAADF-STEM images, which possessed a high Fe loading of 2.69%.

Design, synthesis, and biological evaluation of imidazolidinone derivatives as potent PPARα/δ agonists for the treatment of cholestatic liver diseases.

Cholestatic liver disease (CLD) represents a significant and growing public health concern, and there is a lack of effective therapeutic drug in clinical practice. Peroxisome proliferator-activator receptors α/δ (PPARα/δ) are regarded as potential therapeutic targets for CLD. In this study, a series of novel imidazolidinone PPARα/δ agonists were developed, and the preferred compound 8 displayed potent and well-balanced agonistic activity.
