Water chestnut (Trapa japonica Flerov.) is an annual aquatic plant. In the present study, we showed that the treatment of water chestnut extracted with boiling water resulted in a significant increase 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging activity and decrease the intracellular H2O2-induced accumulation of reactive oxygen species. In addition, water chestnut extract (WCE) inhibited lipopolysaccharide (LPS)-induced nitric oxide production and suppressed mRNA and protein expression of the inducible nitric oxide synthase gene. The cytokine array results showed that WCE inhibited inflammatory cytokine secretion. Also, WCE reduced tumor necrosis factor-α-and interleukin-6-induced nuclear factor-αB activity. Furthermore, during sodium lauryl sulfate (SLS)-induced irritation of human skin, WCE reduced SLS-induced skin erythema and improved barrier regeneration. These results indicate that WCE may be a promising topical anti-inflammatory agent.

The ability to track moisture content using soil moisture sensors in green stormwater infrastructure (GSI) systems allows us to understand the system's water management capacity and recovery. Soil moisture sensors have been used to quantify infiltration and evapotranspiration in GSI practices both preceding, during, and following storm events. Although useful, soil-specific calibration is often needed for soil moisture sensors, as small measurement variations can result in misinterpretation of the water budget and associated GSI performance.

Both fresh and processed Chinese chestnuts are susceptible to retrograde hardening, affecting their texture, flavor, and shelf life because of their high starch content. To reduce the short-term retrogradation of chestnut starch during the food processing of chestnut-based products, a complex of Lonicern caerulea berry polyphenols (LCBP) and chestnut starch (CS) was prepared using high hydraulic pressure (HHP). The results showed that LCBP reduced the water separation rate, hardness, elasticity, and short-range order of retrograde CS under HHP and improved light transmission.

Methylmercury (MeHg) is a widespread contaminant that bioaccumulates in marine food webs, including those in the Mediterranean sea. It poses serious health risks, especially to developing infants and children, where exposure can cause neurological damage and developmental delays. In addition to health concerns, high MeHg levels in seafood can lead to economic losses through cognitive impairments that reduce productivity.

Background: Bubble continuous positive airway pressure (bCPAP) is a low-cost, non-invasive respiratory support therapy for children with respiratory distress, but its effectiveness is dependent on the context. We aimed to understand contextual factors influencing bCPAP implementation for children aged 1-59 months in low-income and middle-income countries (LMICs) and to develop a theory explaining how these factors influence implementation outcomes.
Methods: In this realist review, we generated an initial programme theory comprising candidate context-mechanism-outcome configurations (CMOCs) via review of key references and team discussion.

This study compared the effects of enzyme extraction (E-DF), enzyme-acid extraction (EAc-DF), enzyme-alkaline extraction (EAl-DF), ultrasonic-enzyme extraction (EU-DF), and microwave-enzyme extraction (EM-DF) on the yield, chemical composition, structural characteristics, physicochemical properties, physiological activities, and hypoglycemic activities of dietary fiber (DF) from Chinese chestnut. EAl-DF had the highest yield (25.44 ± 0.
