Genotypic analysis of human papillomavirus in cervical exfoliated cells from women in Zigong.

Background: This study investigated the human papillomavirus (HPV) infection status among women in Zigong from January 2016 to August 2024 and provides a comprehensive statistical analysis of HPV infection characteristics. The findings aim to enhance cervical cancer screening, inform vaccination strategies, and improve HPV infection prevention measures.

Methods: We conducted a retrospective analysis on 48,474 female patients who visited the gynecology department of Zigong Fourth People's Hospital from January 2016 to August 2024.

Unveiling the role of ferroptosis in the progression from NAFLD to NASH: recent advances in mechanistic understanding.

Non-alcoholic fatty liver disease (NAFLD) is a prevalent and significant global public health issue. Nonalcoholic steatohepatitis (NASH) represents an advanced stage of NAFLD in terms of pathology. However, the intricate mechanisms underlying the progression from NAFLD to NASH remain elusive.

Binary Logistic Regression Analysis on the Association of Occlusion with the Temporomandibular Joint Arthralgia in the Partial Denture Wearers-A Retrospective Study.

Purpose: To analyze the potential association between the occlusion features and the incidence of temporomandibular joint (TMJ) arthralgia in patients with partial dentures.

Materials And Methods: A total of 101 partial denture wearers were collected, 45 with unilateral TMJ arthralgia diagnosed according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Binary logistic regression analysis was adopted.

Design, synthesis and biological evaluation of combretastatin A-4 sulfamate derivatives as potential anti-cancer agents.

A series of combretastatin A-4 (CA-4) sulfamate derivatives were synthesized and their structure-activity relationship on tubulin, arylsulfatase and tumor cell antiproliferation inhibition was studied. Among them, compound showed excellent potency as well as CA-4 under the same conditions against six tumor cells including HTC-116, HeLa, HepG2, MGC803, MKN45 and MCF-7 cells, respectively. Molecular docking revealed that several important hydrogen bond interactions were formed between the sulfamate group of and the colchicine binding site of tubulin and steroid sulfatase respectively.

Combining API in a dual-drug ternary cocrystal approach.

A new strategy is developed to design multi-drug solid forms. Using an inorganic salt as the glue sticking together two different APIs in a "drug-bridge-drug" approach, we successfully created and characterized three different ternary ionic cocrystals (TICCs). The link between binary and ternary ICCs and the importance of reaction stoichiometry was investigated using ternary solid-state phase diagrams.

Synthesis of AuPd nanoparticle-decorated graphene-coated ZnO nanorod arrays with enhanced photoelectrochemical performance and stability.

AuPd nanoparticle-decorated graphene-coated ZnO nanorod (ZNR) array electrodes (ZNR@Gr/AuPd) were synthesized electrostatic self-assembly followed by solution reduction methods. The morphologies of ZNR@Gr/AuPd were characterized with scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM), which indicated that ZNR was well-coated by graphene with 3-5 layers and uniformly decorated with AuPd nanoparticles (about 5 nm). UV-Vis diffuse reflectance and photoluminescence spectra were obtained to analyze the optical properties.

Solid-state chiral resolution mediated by stoichiometry: crystallizing etiracetam with ZnCl.

Chiral resolution of racemic etiracetam was achieved via co-crystallization with ZnCl2. Depending on the amount of ZnCl2 either a stable racemic compound or a stable conglomerate can be obtained. Excess ZnCl2 triggers the quantitative conversion of the racemate into the conglomerate solid; this unprecedented behaviour was investigated through a racetam/ZnCl2/solvent phase diagram.

Synthesis and biological evaluation of dehydroepiandrosterone-fused thiazole, imidazo[2,1-b]thiazole, pyridine steroidal analogues.

A series of steroidal[17,16-d]thiazole, steroidal[1,2-b]pyridine and steroidal[17,16-d]thiazole[2,1-b]imidazo products were synthesized through a convenient and productive method. Anti-proliferation activity against EC109 (human esophageal carcinoma), EC9706 (human esophageal carcinoma) and MGC-803 (human gastric carcinoma) cell lines was examined in vitro. Among the screened compounds, several highly potential compounds were located.

Design and synthesis of novel D-ring fused steroidal heterocycles.

Using dehydroepiandrosterone as the starting material, we have synthesized a series of steroid analogs possessing a D-ring fused with heterocycles which are pyridine, imidazo [2,1-b]thiazoles or substituted thiazole imines. All the final structures are first reported and identified by NMR and MS spectroscopys, the yields of these products are moderate to good and the reaction conditions are mild. The cytotoxicity of the synthesized compounds against EC-109(human esophageal carcinoma), EC-9706(human esophageal carcinoma), MGC-803(human gastric carcinoma) were investigated.
