Gallbladder carcinomas (GBCs) are the most common carcinomas of the biliary tract. The clear cell variant is encountered rarely, accounting for approximately 1% of all GBCs.Due to its rarity, the exact incidence and pathogenesis of this variant are unknown. Though hyalinising cholecystitis (porcelain gallbladder) is an established risk factor for development of conventional adenocarcinomas of the gallbladder, its role in the pathogenesis of the rare variants of GBC is not well-established. The current case raises the possibility that clear cell carcinoma of the gallbladder may arise through the same pathways as conventional adenocarcinomas of the gallbladder.

Microbiome gained attention as a cofactor in cancers originating from epithelial tissues. High-risk (hr)HPV infection causes oropharyngeal squamous cell carcinoma but only in a fraction of hrHPV+ individuals, suggesting that other factors play a role in cancer development. We investigated oral microbiome in cancer-free subjects harboring hrHPV oral infection (n = 33) and matched HPV- controls (n = 30).

Background: Endogenous retrovirus (ERV) elements are genomic footprints of ancestral retroviral infections within the human genome. While the dysregulation of ERV transcription has been linked to immune cell infiltration in various cancers, its relationship with immune checkpoint inhibitor (ICI) response in solid tumors, particularly metastatic clear-cell renal cell carcinoma (ccRCC), remains inadequately explored.
Methods: This study analyzed patients with metastatic ccRCC from two prospective clinical trials, encompassing 181 patients receiving nivolumab in the CheckMate trials (-009 to -010 and -025) and 48 patients treated with the ipilimumab-nivolumab combination in the BIONIKK trial.

Hydrogen-substituted graphdiyne (HsGDY) is a two-dimensional material with an sp-sp carbon skeleton featuring a band gap and a porous structure that enhances ion diffusion. In previous reports, HsGDY growth was limited to metal substrates such as Cu, which then required transfer. Here, we developed a sandwich method that allows HsGDY to be grown directly on the target substrate.

Background: Intestinal larva invasion is a crucial step of Trichinella spiralis infection. Intestinal infective larvae (IIL) and their excretory/secretory proteins (ESP) interact with gut epithelium, which often results in gut epithelium barrier injuries. Previous studies showed when T.

Managing uncontrolled and noncompressible bleeding presents a major challenge in emergency trauma care. Methods to halt bleeding quickly and efficiently, without applying direct pressure on the wound, have become a key focus of research. Herein, a novel fructose-modified chitosan/gelatin composite sponge has been developed, exhibiting high elasticity, low rebound pressure, and excellent cell compatibility.
