Summary: Animal models and static cultures of intestinal epithelial cells are commonly used to study Hg(II) transport, but they are unable to accurately simulate the human intestinal microenvironment. This study proposes the use of a gut-on-a-chip with TEER sensors and electrochemical sensors to dynamically simulate the intestinal barrier and monitor Hg(II) transport in real-time. The cellular microenvironment was recreated using fluid shear stress and cyclic mechanical strain, and the absorption of Hg(II) and the expression of Piezo1 and DMT1 were monitored.

Summary: The Augusta Bay in eastern Sicily, Italy, is a highly impacted coastal environment with elevated levels of contaminants due to industrial activities. The concentrations of mercury and hexachlorobenzene were found to be high in sediments and showed strong bioaccumulation in different species. However, after the closure of the chlor-alkali plant in 2003, the bioavailability and biological effects of these contaminants gradually decreased. The persistence of mercury and hexachlorobenzene in the environment has implications for the health of marine organisms and possible risks to human health.

Summary: This study collected soil and tea leaf samples from 69 tea gardens in Anxi, China, and investigated the Hg content in soil and tea leaves, as well as the bioavailability of Hg from soil to tea leaves. The results showed that the Hg content in soil was higher than the background value and varied with different geological backgrounds. In tea leaves, the Hg content was higher in older leaves, and the transfer factor ranged widely. The correlation between Hg content in tea leaves and total Hg content in soil was not significant, but there was a significant positive correlation with the extracted amount of Hg in soil, as well as soil organic carbon and pH value.

Summary: This study examines the distribution of mercury (Hg) levels in fish and fish products in Qatar and their relationships with fish types, weights, protein, and lipid contents. Principal component analysis (PCA) is used to analyze the influence of lipids and protein content on Hg accumulation in fish tissues. Additionally, the impact of Hg concentration and fish consumption on estimated weekly intake (EWI) is studied. Results show that Hg contamination levels are primarily affected by protein-lipid content in predatory species, and high lipid content reflects lower Hg levels indicating a polluted environment. The PCA analysis indicates a strong correlation between EWI and Mercury concentration, except in cases of low Mercury concentration.

Summary: Hempseed is a promising source of plant proteins, with approximately 24% protein content, and edestin makes up the majority of its proteins. Two hempseed protein hydrolysates (HH1 and HH2) were produced using enzymes from different strains for different time periods. These hydrolysates exhibited strong direct antioxidant activity and certain peptides within them were found to be transported across intestinal cells, retaining their antioxidant activity. This suggests that these hempseed hydrolysates could be utilized as sustainable antioxidant ingredients in nutraceutical and/or food industries.

Summary: This pilot study examines the association between measures of childhood and early adolescent adiposity with blood leukocyte DNA methylation at LINE-1 repetitive elements and two genes implicated in growth and adiposity. The results suggest an inverse association between childhood BMI and early-teen weight with H19 DNA methylation, but no significant associations were found between any anthropometric measures and DNA methylation at LINE-1 or HSD11B2. Age-related DNA methylation trajectories do not appear to be influenced by adiposity. Further exploration in larger study populations is needed to confirm these findings.
