Primary tumors of the vagina are extremely rare, accounting for less than 2% of gynecological neoplasms. Among these, mixed tumors with both epithelial and mesenchymal components are exceptional and rarely described in the literature. We report the case of a 50-year-old female patient with a mixed tumor of the vagina, which required multidisciplinary management. Through this observation, we discuss the clinical, radiological, and histopathological features of this rare entity, as well as the ava...

Methylmercury (MeHg) is an extremely dangerous and toxic organometallic compound that has been found to be persistent and recurrent in various compositions of the environment and is highly suspected to cause dangerous problems in ecosystems and public health owing to the accumulative and magnifying effects that it may cause in the food chain. Soil, one of the essential components for both the storage and partial release of MeHg, is a critical medium through which this compound moves within the e...

Large language models (LLMs), such as GPT-based systems, are transforming foreign language education by enabling personalized practice, instant feedback, and immersive interactions beyond traditional computer-assisted language learning (CALL) tools. The article outlines LLMs’ advantages over rule-based systems, analyzes applications across listening, speaking, reading, and writing skills, and addresses risks like overreliance and bias. It emphasizes pedagogy-aligned integration to maximize benef...

Central giant cell granuloma (CGCG) is an uncommon benign intraosseous lesion of the jaws characterized by the proliferation of multinucleated giant cells within a fibrovascular stroma. Although most lesions present as slow-growing and asymptomatic, aggressive forms may cause significant bone destruction and involvement of adjacent anatomical structures. Maxillary localization is relatively rare and may present diagnostic and therapeutic challenges due to the proximity of the maxillary sinus, na...

As a ubiquitous linguistic symbol in modern society, linguistic landscape has become an emerging and popular research topic in the field of sociolinguistics. Against the background of the dissemination and inheritance of intangible cultural heritage (ICH), this project takes Shaoxing wine culture as a sample to examine the current state of the linguistic landscape throughout the entire production-dissemination-consumption chain both online and offline. It deeply explores the characteristics of t...

Background: Periodontitis is a chronic inflammatory disease initiated by pathogenic biofilms, leading to the progressive destruction of periodontal supporting tissues. Green tea catechins, particularly epigallocatechin-3-gallate (EGCG), have emerged as promising therapeutic agents due to their potent antioxidant, anti-inflammatory, and antimicrobial properties. Objective: This review aims to evaluate the clinical and biological efficacy of green tea catechins as an adjunct to scaling and root pl...
