Several studies suggest an inverse relationship between coffee intake and risk of hepatocellular carcinoma (HCC), but the association between green tea intake and the risk of HCC is still inconclusive. We performed a meta-analysis of observational studies to clarify the association. We identified eligible studies published from January 1, 1992, to February 28, 2022, by searching PubMed, Web of Science, and EMBASE. A total of 32 studies were included in the meta-analysis. Among them, 21 studies involving 2,492,625 participants and 5980 cases of HCC reported coffee intake, 18 studies involving 1,481,647 participants and 6985 cases of HCC reported green tea intake, and seven studies reported both coffee intake and green tea intake. The results showed that a higher coffee (RR = 0.53; 95% CI: 0.47-0.59; I2 = 0.0%; Pheterogeneity = 0.634) or green tea (RR = 0.80; 95% CI: 0.67-0.95; I2 = 72.30%; Pheterogeneity < 0.001) intake may be associated with a lower risk of HCC. The same results were observed in both cohort and case-control subgroups. Our findings suggest that drinking coffee or green tea may be a potentially effective approach for the prevention or mitigation of HCC, but this still needs to be confirmed by further well-designed observational studies and clinical experimental research.

Background and objectives With the continuous presence of microflora, saliva, and frequent intake of coloured food, the colour stability of any aesthetic material may become compromised. Hence, the present study was conducted to evaluate the influence of tea, coffee, and turmeric solutions on the colour stability of commercially available heat-cured and autopolymerizing denture base acrylic resins as well as a soft lining material. Methods Twenty-four rectangular samples measuring 20 mm × 15 mm × 2 mm were prepared for each type of test material.

Metabolic-associated fatty liver disease (MAFLD), linked to lipid dysregulation, poses global health risks. 2,2',3,4,4',5'-hexachlorobiphenyl (PCB138) is a persistent organic pollutant that poses potential threats to liver health due to its environmental persistence and bioaccumulation. Theabrown (TB), a natural compound extracted from black tea, exhibits lipid-lowering and antioxidant properties, but its protective effects on PCB138-induced liver injury have not been thoroughly investigated.

In the search for novel succinate dehydrogenase inhibitors (SDHIs) fungicides for managing rice sheath blight (RSB) and sclerotinia stem rot (SSR), 28 pyrazole-4-carboxamides incorporating stilbene or diphenylacetylene scaffolds were synthesized and evaluated for antifungal activities. The results showed that compound exhibited the most promising antifungal efficacy against and with EC (half maximal effective concentration) values of 0.004 and 0.

In this study, a novel bleaching method for ramie cellulose fibers with low oxidative damage was developed by utilizing the properties of sodium percarbonate contained in tea saponin, which slowly releases hydrogen peroxide in the catalytic oxidation system of N-hydroxyphthalimide (NHPI). First, the bleaching process was optimized using response surface design, followed by comparison and characterization of fiber properties prepared under different bleaching systems. Finally, the energy consumption, water consumption, and toxicity of the NHPI/tea saponin system were evaluated.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.
