Two-Phase Perchlorate Activation Enabled by a Dinuclear Fe-NHC (N-Heterocyclic Carbene) Complex.

Perchlorate, initially regarded as a weakly coordinating counterion rather than a reactive oxidizing reagent due to its kinetic stability, has garnered attention for its potential in microbial systems. Under anaerobic conditions, microbes utilize perchlorate as a terminal oxidant for methane oxidation, involving two distinct stages: extraction and release of oxidizing ability. This two-phase activation process necessitates the collaborative action of multiple enzymes, a phenomenon not extensively explored in artificial systems.

Efficacy and safety of inclisiran versus PCSK9 inhibitor versus statin plus ezetimibe therapy in hyperlipidemia: a systematic review and network meta-analysis.

Overweight and obesity are closely related to an increase in SUA.

Prenatal exposure to di-n-butyl phthalate promotes RIPK1-regulated necroptosis of uroepithelial cells and induces hypospadias through the epithelial-mesenchymal transition process in newborn male rats.

Maternal exposure to di-n-butyl phthalate (DBP) has been linked to the induction of hypospadias; however, the underlying mechanism remains unclear. Necroptosis is reported to be implicated in developmental malformations. This study aimed to investigate the underlying mechanism of necroptosis in the development of hypospadias.

Imine bond-directed assembly of polyoxometalate-based metal-organic frameworks.

Polyoxometalate-based metal-organic frameworks (POMOFs) are highly effective heterogeneous catalysts that combine the catalytic activity of polyoxometalates (POMs) with the high surface area, tunable porosity, and structural diversity of MOFs. Nevertheless, there is still a lack of a general method to integrate POMs with various transition metal-based building units into POMOFs under mild conditions. In this work, we employed imine bonds to link amino-functionalized Anderson-type POMs with aldehyde-terminated divalent metal clusters, resulting in a series of isostructural POMOFs, M(II)-POMOFs (M = Zn, Co, Mg, or Mn).

Insight into prostate cancer osteolytic metastasis by RelB coordination of IL-8 and S100A4.

Background: Although RANK-LRANK interaction is essential for osteoclastogenesis, the mechanisms by which cancer cells invade bone tissues and initiate osteolytic metastasis remain unclear. Here, we show that the hyperactivation of RelB fosters prostate cancer (PCa) osteolytic metastasis by coordinating interleukin-8 (IL-8) and calcium-binging protein A4 (S100A4).

Methods: The factors promoting PCa bone metastasis were investigated in sera from PCa patients and tumour tissues derived from nude mice using immunohistochemical analysis and enzyme-linked immunosorbent assays (ELISA).

Effects of phytic acid from soybean meal on Maillard reaction and antioxidant properties of products.

This study used glycine (Gly), glucose (Glu), and soybean meal phytic acid (PA) as raw materials to investigate the effect of different PA addition amounts on the Gly-Glu Maillard reaction system and the antioxidant capacity of the products through rheological properties, particle size, chromatography, and other methods. The results showed that with the addition of PA, the apparent viscosity and average particle size of the system decreased, the thermal denaturation temperature increased, the product concentration decreased, the color became brighter, and the antioxidant performance was enhanced. This indicates that PA reacts with Gly and Glu to form PA - Gly and PA - Glu complexes, respectively, and hinders the Maillard reaction.
