Summary: Previous studies have shown that haemodialysis patients have an increased risk of trace element imbalances. In this study, both serum and whole blood concentrations of a wide panel of trace elements in haemodialysis patients were determined and compared with those of a control group. The results indicate that chronic haemodialysis may affect intra- and extracellular blood compartments differently, leading to significant trace element imbalances.

Summary: Rare earth elements are crucial tools in geological studies, but accurate determination of their concentrations can be challenging in samples with low REE levels and high interfering barium levels. This study developed a simple, RE resin-based separation method that showed good REE recovery and efficient removal of matrix elements, particularly barium, making it suitable for precise determination of Eu contents in rock samples with high barium content.

Summary: The study found that red wines contain higher levels of certain elements compared to other wine types (white and rose), while white wines have higher levels of other elements and rose wines have higher concentrations of iron and uranium. The study also revealed that in some samples, the maximum levels of certain metals slightly exceeded OIV standards, but overall the wines contained lower levels of heavy metals, suggesting they are safe for consumption. Additionally, wines from Poland, USA, and Australia showed distinctive elemental fingerprints, with different characteristic metals for identification of country of origin.

Summary: Honey is highly valued for its beneficial properties, but it is also susceptible to counterfeiting. Analytical methods are being developed to verify its origin and authenticity using trace- and ultra-trace elements. Lanthanides have been found to be particularly useful for tracing the link between honey and the soil it originates from. The study used ICP-MS and ICP-OES analysis to investigate the traceability of 17 different honey chains, and found that while the soil fingerprint remains unchanged, there is slight fractionation of heavier lanthanides from flowers to honey.

Summary: The interest in determining the chemical composition of textile products has increased due to toxicological issues and environmental concerns. This study analyzed the levels of twenty trace elements in clothing items commercialized in Spain and evaluated the potential health implication of dermal exposure in early life. Aluminum, zinc, and titanium showed the highest concentrations, while chromium was found in high levels in black polyester. Dermal exposure to titanium was associated with a hazard quotient higher than the threshold value, indicating potential risks for pregnant women and newborns.

Summary: The study conducted in communities directly affected by the disaster revealed high levels of exposure to toxic metals such as aluminum, arsenic, mercury, and nickel. Factors such as community, drinking water, fish and seafood consumption, and smoking habits were found to be associated with metal/metalloid levels in their body. Well and tap water intake were identified as important sources of exposure to aluminum and nickel. The findings represent health risks to the groups living in the areas affected by the tailings dam failure, calling for further studies to evaluate the potential health effects of high exposure to metals and remediation actions from public health Brazilian authorities.

Summary: The study investigates the involvement of cellular prion protein (PrPC) in neuroprotection under oxidative stress. The presence of PrPC showed resistance to oxidative stress in astrocytes, and PrPC plays a role in metal homeostasis and prevents protein aggregation. Additionally, PrPC can translocate SOD1 to cell nuclei under oxidative stress, potentially controlling DNA damage. Overall, the study suggests that PrPC activates cellular response and defense against oxidative stress, protecting neurons and ensuring astrocyte functionality.

Summary: The purpose of this research was to investigate the negative effects of salt stress on soybean plants in terms of anatomical, morphological, nutritional, physiological, and biochemical parameters. The study found that concentrations of 50 to 200 mM Na+ significantly reduced the levels of K, Ca, and Mg in the plants, and had negative effects on photosynthesis, gas exchange, and photosynthetic pigments, which were likely caused by oxidative stress. Interestingly, at concentrations below 100 mM Na+, there were changes in epicuticular wax deposition, stomatal quantity and morphology, and leaf epidermis thickness in soybean plants. Overall, significant deleterious effects were observed in soybean plants under salt stress conditions above 100 mM Na+.

Summary: Occupational exposure to potentially toxic elements in informal jewelry production can have adverse health effects on workers. This study used proteomic and metabolomic analyses to assess the impact of these exposures on workers' exposome in Limeira city, Brazil. The results showed high levels of Sn and Cu in welders' blood, as well as correlations between certain proteins and blood PTE levels. Additionally, pathway analysis revealed seven metabolic pathways potentially disturbed by the informal work. These findings highlight the harmful effects of PTE exposure in the jewelry production industry.

Summary: This study investigated the effects of zinc oxide nanoparticles, nitric oxide donor, and their combination on the enzymatic and photosynthetic profile, as well as element accumulation, in rice plants. The results showed that these treatments increased the concentration of zinc and iron, and caused a mild disturbance in the antioxidant system. However, these disturbances did not significantly affect the yield, growth, or photosynthetic pigment production of rice plants.
