The long-term mining of vanadium-titanium (V-Ti) magnetite has generated a large accumulation of tailings, which can lead to metal pollution via microbial bioleaching. Current research has focused on the bioleaching of minerals, and a few studies have explored microbial responses to metals only through limited metabolite concentrations. However, the trigger mechanisms of metal release during the V-Ti magnetite tailing bioleaching and key gene regulatory pathways for organic acid metabolism are still unclear.

Results showed antioxidant (selenium) was associated with reduced oxidation of n-3 pork during processing and digestion. SV significantly reduced the oxidation of pork proteins and lipids and the loss of polyunsaturated fatty acids (PUFAs) compared with other processing methods.

Background: Xinkeshu (XKS) formula is a patented traditional Chinese medicine used to treat cardiovascular diseases for decades. However, little is known about its potential influence on heart metabolism under pathological conditions.
Purpose: This study sought to explore the potential role of XKS in pathological cardiac hypertrophy, with a focus on metabolic remolding.
Tumor therapy has historically been a global research focus, with phototherapy garnered significant attention as a innovative treatment modality. However, the antioxidant defense system in the tumor microenvironment, characterized by excessive glutathione (GSH) and thiol-containing proteins, often limits the effectiveness of photodynamic therapy. In this study, we report the development of a new multifunctional integrated nanozyme with thioredoxin reductase-oxidase (TrxRox) and GSH-oxidase (GSHox)-like activities.

Despite separate studies on both illnesses, no research has directly examined the link between depressive symptoms and periodontitis in obese people. Given the close correlation between obesity and chronic illnesses, as well as the possibility of a bidirectional impact between depressive symptoms and periodontitis, this study aims to investigate the link between depressive symptoms and periodontitis in an obese population.

Oxidation of the sub-arc mantle driven by slab-derived fluids has been hypothesized to contribute to the formation of gold deposits in magmatic arc environments that host the majority of metal resources on Earth. However, the mechanism by which the infiltration of slab-derived fluids into the mantle wedge changes its oxidation state and affects Au enrichment remains poorly understood. Here, we present the results of a numerical model that demonstrates that slab-derived fluids introduce large amounts of sulfate (S) into the overlying mantle wedge that increase its oxygen fugacity by up to 3 to 4 log units relative to the pristine mantle.

The earliest effort in 2007 focused primarily on mass spectrometry and nuclear magnetic resonance spectroscopy and resulted in four recommended levels of metabolite identification confidence─the Metabolite Standards Initiative (MSI) Levels. In 2014, the original MSI Levels were expanded to five levels (including two sublevels) to facilitate communication of compound identification confidence in high resolution mass spectrometry studies.

Materials And Methods: Data on edentulism in older adults were collected from the 2021 global burden of disease (GBD) study. Disease burden trends were analyzed using a joinpoint model.
In recent years, the influence of dietary-related factors on neurodegenerative diseases has received considerable attention in the academic community, notably involving the food additive sodium nitrite (NaNO) and intermittent fasting behavior. However, the effects of NaNO and intermittent fasting on spatial learning and memory have not been thoroughly investigated. This study conducted a controlled experiment to explore the impact of NaNO and intermittent fasting on the hyperphosphorylation of hippocampal neurofilament (NF) and tau proteins, as well as spatial learning and memory in rats.

Central post-stroke pain (CPSP) is a chronic neuropathic pain syndrome that commonly occurs after cerebral stroke, and it severely impairs the daily activities of stroke patients. A number of fundamental and clinical studies support the theory that CPSP is mainly caused by ischemic and hemorrhagic injury of the spinal-thalamic-cortical neural pathway. However, the underlying reasons of CPSP genesis and development are far from clear.

The generalized Kerker effect (GKE) arising from the interference of high-order multipoles has attracted more interest due to its direct correlation with various functionalities in nanophotonics. The realization of the GKE at oblique incidence is highly desired yet remains underexplored. Herein, we report the experimental observation of the GKE by leveraging quasi-bound states in the continuum (QBICs) supported by a silicon metasurface.
