In order to evaluate the reliability of the ID ICP-MS method for the measurement of magnesium, zinc, and copper in human serum, we investigated the traceability, precision, trueness, and uncertainty of the method. This method traces the contents of magnesium, zinc, and copper in human serum to the standard materials NIST SRM3131a, SRM3168a, and SRM3114 respectively, thus completing the traceability to SI unit. The repeatability of this method for measuring magnesium, zinc, and copper in the human serum reference material GBW09152 was found to be 0.2%, 0.7%, and 0.6% ( = 9), respectively. The measurement, when employed to measure the magnesium, zinc, and copper in standard materials, had caused a maximum deviation of less than 0.88%, 1.35%, and 1.15%, respectively. The measurement results are within the stated uncertainty range of standard materials. The expanded uncertainties were 0.2 mg·kg, 0.04 mg·kg, and 0.08 mg·kg ( = 2) for magnesium, zinc, and copper, respectively. Therefore, this method has high trueness, good reproducibility, and simple operation and is suitable for tracing the values of magnesium, zinc, and copper in human serum.

Background: Sub-Saharan Africa is facing a dietary transition with both undernutrition and rising rates of non-communicable diseases. Adopting the reference diet proposed by the EAT-Lancet Commission can reduce both the environmental burden and improve health outcomes. However, whether this diet provides micronutrient adequacy in older adults in low-income settings has not been investigated.

Background: Colorectal cancer (CRC) is a highly prevalent and fatal malignancy worldwide. Despite advancements in early screening techniques and treatments, the prognosis for patients remains suboptimal. Studies have shown that metal ions play crucial roles in the occurrence, progression, and treatment of CRC.

Background: Gestational diabetes mellitus (GDM) is a common pregnancy complication closely associated with increased oxidative stress. The Oxidative Balance Score (OBS) integrates dietary and lifestyle factors influencing oxidative stress, yet its relationship with GDM remains unclear.
Methods: In this case-control study, 150 pregnant women with GDM and 170 healthy controls were recruited from primary healthcare centers in Urmia, Iran.

Rising atmospheric carbon dioxide (CO₂) levels are expected to enhance biomass and yield in C crops. However, these benefits are accompanied by significant reductions in the concentrations of essential nutrients in both foliar and edible tissues, posing potential global nutritional challenges. In this study, we grew three soybean cultivars (Clark, Flyer, and Loda) in ambient ( ~ 438 ppm) and elevated CO₂ ( ~ 650 ppm) conditions using open top chambers and measured changes in leaf-level physiological responses, biomass accumulation, and nutrient concentrations across developmental stages.
