Summary: This study evaluated the expression levels of certain molecules in patients with depressive disorders and controls. The results showed decreased expression of DIO2 and increased expression of IL1B, IL6, and TNFA in patients. Protein concentrations also showed corresponding changes. The AUC of IL-1 beta, IL-6, DIO1, and DIO3 proteins was >0.7, suggesting their potential as biomarkers for distinguishing patients with depressive disorders. Further studies are recommended to understand the exact role of these molecules.

Summary: This study aimed to investigate the effects of peripheral iodothyronine deiodinases (DIOs) on thyroid hormone economy. The results showed that D2 could enhance local thyroid hormone action and promote its circulation, while D3 could decrease circulating T3 and T4 levels with elevated reverse T3, leading to consumptive hypothyroidism. Additionally, the D3 mice are expected to be a novel hypothyroidism model.

Summary: The emergence of ferroptosis as a cell death pathway associated with brain disorders highlights the importance of developing therapeutics targeting the brain and protecting neurons. Selenium compounds have shown to be effective in inhibiting ferroptosis, with organic selenium compounds like methylselenocysteine providing protection against neuronal damage in ischemia-reperfusion injury in vivo. This suggests the potential use of ferroptosis inhibitors and specific selenium compounds in preventing neuronal damage in ischemic stroke and other related brain diseases.

Summary: Using high-resolution X-ray crystallography, the study visualized tRNA-dependent conformational changes in human SepSecS and showed that tRNA(Sec) binding organizes the active sites of the catalytic protomer. The study also demonstrated that productive SepSecS·tRNA(Sec) complex formation is driven by electrostatic interactions between tRNA(Sec) and SepSecS. This research provides a structural basis for understanding the terminal reaction of Sec formation.

Summary: This study investigated the effects of dietary supplementation of two different forms of selenium on nutrient digestibility, milk yield, blood biochemical parameters, and lamb performance in ewes. The results showed that supplementation of bio-nanostructured selenium (SeNSM) improved the digestibility of neutral detergent fiber, blood glutathione peroxidase activity, milk yield, and milk composition compared to the control group. Ewes fed SeNSM also had lambs with higher body weight gains. In conclusion, SeNSM was more effective than sodium selenite (SS) in improving the productive performance of both ewes and their lambs.

Summary: This study examined the effects of dietary selenium nanoparticles (Se-N) on the performance of whiteleg shrimp juveniles. The results showed that supplementing the diet with Se-N improved the growth performance and feed conversion ratio of the shrimp. Increasing levels of Se-N in the diet also led to higher selenium levels in the shrimp's body. Additionally, Se-N supplementation increased the activities of certain enzymes and reduced oxidative stress in the shrimp.

Summary: This study investigated the transport of selenium through the soil-crop-human chain in regions with different selenium levels. It found that the residents' dietary selenium intake was related to the selenium content in soil, with one village within the WHO recommended intake range while the other village was at risk of selenium deficiency. There were significant positive correlations between residents' dietary selenium intake and the three selenium biomarkers.

Summary: C57BL/6 mice and BALB/c mice showed different expression profiles of selenoprotein P after a high-fat diet (HFD). C57BL/6 mice in the HFD group had higher body weight, fasting plasma glucose levels, and plasma selenoprotein P levels compared to the ND group. However, BALB/c mice did not show significant differences in fasting plasma selenoprotein P levels between the HFD and ND groups.

Summary: This study aims to investigate the protective effects of Vitamin E (Vit E) on manganese (Mn)-induced nigrostriatal system lesions. The results demonstrate that Vit E improves behavioral disorders, attenuates the loss of nigral dopaminergic neurons, and restores mitochondrial function. Additionally, the protective effect of Vit E may be associated with the upregulation of CHRM1 and KCNJ4 mRNA.

Summary: The study illustrates the changes in iodized salt usage, goiter rate, and median urinary iodine concentration in school-aged children in Chongqing over the past 21 years. Adequate iodized salt consumption can eliminate iodine deficiency disorders in children, but excessive iodine intake from salt can lead to high urinary iodine excretion and even goiter. Continuous monitoring and adjustment of iodine fortification levels in household table salt is crucial.

Summary: The zinc coordination complex ZnMD, synthesized in this study, showed promising effects in treating hypertension and cardiac hypertrophy. It was more effective than the antihypertensive drug MD in reducing blood pressure and preventing myocardial hypertrophy. ZnMD also exhibited protective effects on the heart by reducing oxidative damage and regulating the expression of oxidative enzymes. These findings suggest that ZnMD has the potential to be developed as a therapeutic drug for hypertension and cardiac dysfunction.

Summary: This study investigates the neuro effects of lanthanides on different brain areas in rats and finds that they can distribute and accumulate in various brain regions. Treatment with cerium nanoparticles or lanthanum causes a significant decrease in norepinephrine, dopamine, serotonin, and GABA, accompanied by a significant increase in 5-hydroxyl indoleacetic acid levels. Moreover, cerium nanoparticles exhibit high activity in scavenging free radicals.
