Antioxidant and hepatic fibrosis-alleviating effects of selenium-modified Bletilla striata polysaccharide.

Liver fibrosis is a significant precursor to cirrhosis and liver cancer, yet effective treatments remain elusive. Our previous studies demonstrated that Bletilla striata polysaccharide (BSP) has therapeutic effects, though it performed poorly at medium concentrations. To address this limitation, BSP underwent selenization modification.

Taeniasis impacts human gut microbiome composition and function.

Human taeniasis, caused by Taenia tapeworms, is a global parasitic disease with significant implications for public health and food safety. These tapeworms can grow to considerable sizes and potentially impact the microecology of the host gut. Despite their importance, the effects of Taenia infection on host gut microbiota haven't been thoroughly investigated.

Isomers are more likely to cause collapse of Daphnia magna populations than Di-(2-ethylhexyl) phthalate (DEHP).

Di-(2-ethylhexyl) phthalate (DEHP) is the most commonly used phthalate and is ubiquitous in surface water. Based on its well-established toxicological profile, many countries and regions have adopted specific environmental quality standard (EQS) for DEHP. In China, the EQS value for DEHP is 8 μg/L.

Structural characteristics of a novel Bletilla striata polysaccharide and its activities for the alleviation of liver fibrosis.

Liver fibrosis has proven to be the main predisposing factor for liver cirrhosis and liver cancer; however, an effective treatment remains elusive. Polysaccharides, with low toxicity and a wide range of bioactivities, are strong potential candidates for anti-hepatic fibrosis applications. For this study, a new low molecular weight neutral polysaccharide (B.

A mechanistic effect modeling approach to the prioritization of hidden drivers in chemical cocktails.

Exposure to a single chemical does not exist in reality. Mixtures, which are the ecological norm, are often characterized by numerous intrinsic driving factors with unknown combined effects. Interactions between heterogeneous chemicals, or chemical and nonchemical stressors, could alter their toxicity traits relative to single exposure.
