Staple food is a crucial exposure route for the human intake of potentially toxic elements (PTEs), but it has been neglected in previous human health risk (HHR) studies. Lack of attention to this issue will lead to an underestimation of HHR caused by PTEs. This study establishes a comprehensive regional identification method for health risk assessment (HRA), namely, soil-maize health risk assessment (SMHRA) and applies it to Ziyang, Shaanxi, which is a typical agricultural county.

Article Synopsis
  • SELENOS, a vital selenoprotein, is linked to cancer development and its expression levels were studied to understand their impact on prognosis in lower-grade gliomas (LGG).
  • The study utilized various databases to compare SELENOS expression in normal vs. tumor tissues and found significant correlations with patient prognosis and immune infiltration in LGG.
  • Results indicated that SELENOS was overexpressed in LGG, negatively associated with chemotherapy response to temozolomide, and interacted with multiple proteins related to LGG tumor progression.

Background: The antioxidant enzyme is a selenoprotein that transports selenium in blood and maintains its levels in peripheral tissues. Aberrant expression is strongly linked to the development of some tumors. However, there is a scarcity of studies examining the pan-cancer expression patterns and prognostic relevance of .

Widely targeted metabolomics were performed to explore the differences in glucosinolate and odor-active compound levels between flowering Chinese cabbage powder (FCCP) under vacuum-drying and oven-drying conditions. Twenty-three aliphatic, five indole, and three aromatic glucosinolates were identified in two pretreated FCCP. Higher aliphatic glucosinolate levels were retained in vacuum-dried cabbage powder compared to oven-dried samples, and they were negatively correlated with treated temperatures.

The objective of the current study was to explore the potential mechanism of Ziyang selenium-enriched green tea polysaccharide (Se-GTP) against obesity. The results showed that Se-GTP significantly alleviated obesity and related metabolic disorders caused by high-fat diet (HFD) in mice. 16S rRNA gene sequencing results revealed that Se-GTP improved gut microbiota disturbance of obese mice and facilitated proliferation of probiotics such as , , , and .

Selenium (Se) is a dietary essential trace element for humans with various physiological functions and it could also be accumulated by some plant species, like Astragalus bisulcatus, Stanleya pinnata, and Cardamine hupinshanensis. A novel Gram-stain-negative, facultatively anaerobic, selenite-tolerant bacterium, designated strain YLX-1 , was isolated from the rhizosphere of a Se hyperaccumulating plant, Cardamine hupingshanensis in Enshi, China. Phylogenetic analysis based on 16 S rRNA gene sequences indicated that strain YLX-1 is a potential new species in the genus Wautersiella.

Introduction: Broccoli sprouts have great health and commercial value because they are rich in sulforaphane, a special bioactive compound that helps to prevent chronic diseases, such as cancer and cardiovascular disease.

Objective: The aim of this study was to increase the levels of active substances in broccoli sprouts and understand their metabolic mechanisms.

Methodology: Metabolomics based on liquid chromatography-tandem mass spectrometry and transcriptome analysis were combined to analyse the enrichment of metabolites in broccoli sprouts treated with cold plasma.

Postharvest senescence and quality deterioration of fresh tea leaves occurred due to the limitation of processing capacity. Refrigerated storage prolongs the shelf life of fresh tea. In this study, quantitative fusion omics delineated the translational landscape of metabolites and proteins in time-series (0-12 days) refrigerated tea by UHPLC-Q-Orbitrap HRMS.

Selenium (Se)-enriched green tea has been recognized as a possible source of supplemental Se, while the structural and physiological activities of Se-containing flavone are still unclear. In this study, a Se-containing flavone was isolated from Se-enriched green tea by high-speed counter-current chromatography (HSCCC) and characterized through UHPLC-Q-Orbitrap, FT-IR and NMR. Results proved that HSeO can be combined with the alcohol hydroxyl of 2-phenylchromone in flavone and the content of Se-containing flavone in tea was 15690.

Objective To investigate the relationship between the expression of glutathione peroxidase(GPX)genes and the clinical prognosis in glioma patients,and to construct and evaluate the model for predicting the prognosis of glioma. Methods The clinical information and GPX expression of 663 patients,including 153 patients of glioblastoma(GBM)and 510 patients of low-grade glioma(LGG),were obtained from The Cancer Genome Atlas(TCGA)database.The relationship between GPX expression and patient survival was analyzed.

Background: Selenium (Se) is a vital trace element playing its biological functions through selenoprotein, which has been implicated in various physiological and pathological processes. A growing number of studies indicate that low Se increases the risk of cardiovascular diseases (CVDs). This meta-analysis aimed to compare and analyze differences in Se levels between patients with heart failure (HF), myocardial infarction (MI), coronary heart disease (CHD), and healthy people.

Background: This updated and comprehensive meta-analysis study sought to explore the changes of seven essential trace elements, including selenium (Se), iron (Fe), zinc (Zn), manganese (Mn), fluorine (F), iodine (I) and copper (Cu) in Kashin-Beck disease (KBD) patients compared with healthy individuals. The findings of the current study will provide a valuable reference for implementation of early clinical intervention and prevention of KBD.

Chloride (Cl-) is pervasive in saline soils, and research on its influence on plants has mainly focused on its role as an essential nutrient and its toxicity when excessive accumulation occurs. However, the possible functions of Cl- in plants adapting to abiotic stresses have not been well documented. Previous studies have shown that the salt tolerance of the xerophytic species Pugionium cornutum might be related to high Cl- accumulation.

Hordeum brevisubulatum, called as wild barley, is a useful monocotyledonous halophyte for soil improvement in northern China. Although previously studied, its main salt tolerance mechanism remained controversial. The current work showed that shoot Na concentration was increased rapidly with stress time and significantly higher than in wheat during 0-168h of 100mM NaCl treatment.
