It has been claimed that consumptions of Abrus cantoniensis (AC) and Abrus mollis (AM) as folk beverages and soups are good to cleanse liver toxicants and prevent liver diseases. There is scant information on the phytochemical profiles and antioxidant activities of these two varieties. Five major phytochemicals in these two cultivars were qualitatively and quantitatively compared using UPLC-PDA. A high level of total phenolic content (TPC) and total flavonoid content (TFC) was found in AC and AM. AC, in general, showed some antioxidant activities comparable to that of BHT, and stronger radical scavenging activities and higher reducing power than that of AM (p<0.05). When principal component analysis (PCA) was applied, high correlation between TPC, TFC and their antioxidant activities was found. Hence, this study proved that, both AC and AM could serve as antioxidant-rich component in foods or beverages to promote health function.

Mesenchymal stromal cell (MSC) therapy holds great promise for treating myocardial infarction (MI). However, the inflammatory and reactive oxygen species (ROS)-rich environment in infarcted myocardium challenges MSC survival, limiting its therapeutic impact. In this study, we demonstrate that chemical modification of MSCs with anti-VCAM1 and polydopamine (PD) significantly enhances MSC survival and promotes cardiac repair.

Food allergy has had a rapid rise in prevalence, and thus it is important to identify approaches to limit the development of food allergy early in life. Because maternal dietary supplementation with α-tocopherol (α-T), an isoform of vitamin E, during pregnancy and nursing increases neonate plasma levels of α-T and can limit neonate development of other allergies, we hypothesized that α-T can limit development of food allergy. To assess this, male mice with mutations in their skin barrier genes (FT-/- mice) were mated with wild-type females that received a diet supplemented with α-tocopherol or a control diet.

Oxidative stress is a key factor in melanoma progression, making it an important therapeutic target. This study explored the effects of tangeretin, a citrus-derived flavonoid, on human melanoma A375 cells and its underlying mechanisms. A375 cells were treated with tangeretin at various concentrations.

Naphthenic acids (NAs) are indigenous and complex components in petroleum. In the context of increasing global energy demand, the increasing extraction of fossil resources leads to increased environmental release of NAs, resulting in various environmental risks. However, the impact of NAs exposure on soil microorganisms remains still unclear.
