During the median follow-up of 21.3 (15.0-32.4) months, 130 individuals progressed to anuria. The mean concentration of serum magnesium was 0.9 ± 0.15 mmol/L. After multivariate adjustment, the association of serum magnesium with the risk of anuria was not significant in the entire study population. However, for PD patients with better preservation of RRF, the risk of anuria decreases significantly as serum magnesium increases (HR for per standard deviation increment 0.53, 95% CI 0.32-0.88). The protective effect of increased serum magnesium concentrations on RRF was more pronounced among PD patients with lower triglyceride glucose (TyG) index at baseline compared to those with higher TyG index (p for interaction = 0.03).

To evaluate the linear association between PD and dietary intake of Mg or MDS, we conducted weighted logistic regression for univariate analysis and multivariate linear regression models. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression models. A restricted cubic spline (RCS) was drawn to visualize the nonlinear relationship between MDS/dietary Mg intake and PD. In addition, we examined the variations in the relationship between MDS and PD across different confounding factors of the association using subgroup analysis. There were 240 PD cases (1.2%), and 19770 non-PD were included in the study. We found that a higher MDS was associated with an increased risk of PD after adjusting for covariates (OR per 1-unit increase, 1.47; 95% CI, 1.16-1.86). There is insufficient evidence to support a significant statistical association between Mg intake and the risk of PD. According to nonlinear regression, high MDS was associated with higher odds of PD and lower odds of PD above 250 mg/day intake of Mg.

Additionally, genotoxic and ultrastructure studies of midgut epithelial cells in 3rd instar larvae revealed DNA damage and cell lysis, including destruction of the cell membrane, microvilli, and nuclei. These findings suggest that SeNPs have an adverse effect on AChE gene expression, resulting in its downregulation. This downregulation can be attributed to the formation of reactive oxygen species induced by SeNPs that can modulate the host defense mechanism leading to apoptosis and subsequent larval mortality.

We examined the cell viability of NaB, calcitriol, or the combination of NaB and calcitriol on HepG2 cells and healthy human hepatic stellate cells (HHSC) using MTS. Our findings showed that combination therapy with 3.3 mM NaB and 1 µM calcitriol has a synergistic effect and a more cytotoxic effect on HepG2 cells. This combination significantly increased apoptosis and ROS levels compared to treatment alone with NaB or calcitriol. Gene expression and proteomics analysis revealed inhibition of DNA replication and the cell cycle process, further confirming the potent anti-proliferative effects of the combination therapy. When HepG2 cells were treated with a combination of 3.3 mM NaB and 1 µM calcitriol, mRNA levels of apoptosis-related genes AKT1 and MDM2 were downregulated, while p53 was upregulated. Additionally, cell cycle-related genes CDKN1A, GADD45A, and p27 were upregulated, whereas MCM2, MCM5, and MCM7 were downregulated. Furthermore, genes associated with the vitamin D receptor (VDR), including VDR and CYP24A1, were upregulated, while CYP27B1 was downregulated.
