SR-A3 suppresses AKT activation to protect against MAFLD by inhibiting XIAP-mediated PTEN degradation.

Scavenger receptor class A member 3 (SR-A3) is implicated in metabolic diseases; however, the relationship between SR-A3 and metabolic dysfunction-associated fatty liver disease (MAFLD) has not been documented. Here, we show that hepatic SR-A3 expression is significantly reduced in human and animal models in the context of MAFLD. Genetic inhibition of SR-A3 in hamsters elicits hyperlipidemia, hyperglycemia, insulin resistance, and hepatic steatosis under chow-diet condition, yet escalates in diet-induced MAFLD.

Immobilization and release behaviors of uranium mediated by the redox processes between manganese oxides and dissolved organic matter: Effects of pH and goethite.

Both manganese dioxide (MnO₂) and dissolved organic matter (DOM) exert a significant influence on the chemical species of uranium in the contaminated soils, yet the impacts of the interactions between MnO and DOM, particularly in the presence of iron oxyhydroxides, on the environmental behaviors of uranium have not been elucidated. In this study, the dynamic behaviors of uranium were investigated during the reactions of DOM with δ-MnO in the presence of goethite at different pH values, by employing a combination of kinetic experiments, spectrophotometric titration, X-ray photoelectron spectroscopy, and electrochemical analysis. Our results indicated that the presence of DOM decreased uranium adsorption on MnO and promoted the release of uranium bound to DOM and MnO through the oxidation of DOM and the reduction of MnO, respectively.

Retention of high-pressure solution-processable metastable phase to ambience via differential sublattice rigidity for broadband photodetectors.

Materials science exploits only properties that are available at ambience. Therefore, although high-pressure changes the physical state of all condensed matter, most of the extraordinary properties discovered vanish after decompression and cannot be utilized. Here, we demonstrate sublattice decoupling in a mixed-anion chalcohalide RbReSI upon compression, in which the [RbI] framework is soft and plastic, while the [ReSI] clusters are hard and elastic.

Background: Kinesin family member 13B (KIF13B), a crucial motor protein, exerts multiple cellular biological functions. However, the implication of KIF13B in metabolic dysfunction-associated fatty liver disease (MAFLD) has not been explored yet. This study aimed to investigate KIF13B's role and underlying mechanism in MAFLD and proposes it as a potential pharmacological target.

Assessing the interaction of oceanic and riverine processes on coastal phytoplankton dynamics in the East China Sea.

Unlabelled: The interaction of riverine inputs and ocean current systems causes complex spatiotemporal variations in phytoplankton dynamics in marginal seas of the northwest Pacific Ocean, yet quantitative assessments of these variations and their causes remain limited. Here we evaluate phytoplankton biomass and community structure changes using lipid biomarkers, accompanying ocean circulation and nutrient variations in surface waters collected in spring and summer of 2017-2018 at 118 sites in the East China Sea off the Zhejiang coast. High biomass of diatoms, inferred from brassicasterol concentrations, shifted from the south in spring to the north in summer, while high dinoflagellate biomass, inferred from dinosterol concentrations, occurred mainly in the Changjiang (Yangtze) River plume and adjacent areas in both seasons.

Construction of Multifunctional Composite Films with Biomimetic Bridging and Stress Dissipation Properties.

Strategies based on biodegradable polymers to replace traditional petroleum-based plastics have become research hotspots, while designing multifunctional composite films as packaging materials remains a challenging task. Herein, mussel-inspired hollow mesoporous polydopamine (HMPDA) is prepared and used as a secondary reaction platform to immobilize silver nanoparticles (HMPDA@Ag), which are then co-doped into a polyvinyl alcohol (PVA) matrix in combination with naturally derived 2D montmorillonite (MMT). Benefiting from the noncovalent interactions between the composite particles and MMT with the PVA matrix, as well as the synergistic effects between nanofillers, the fabricated films exhibit a great tensile strength of 424.

However, whether necroptosis occurs in IECs during liver cirrhosis and whether sodium butyrate (NaB) can regulate necroptosis have not yet been reported.

Endogenous Iron(II) Self-Enriched Fenton Nanocatalyst via FTH1 Activity Inhibition and Iron(III) Reduction for Amplified Cancer Ferroptosis Therapy.

Due to the increased expression of iron storage proteins in cancer cells, utilizing the endogenous iron-catalyzed Fenton reaction for cancer ferroptosis therapy has recently emerged as a prominent research focus. However, endogenous iron primarily exists within ferroxidase FTH1 in the Fe (III)-bound state, hindering the effective catalysis of the Fenton reaction. Herein, an endogenous iron(II) self-enriched Fenton nanocatalyst (BAI@cLANCs) is fabricated by encapsulating the FTH1 inhibitor baicalin (BAI) in cross-linked lipoic acid nanocarriers (cLANCs) to amplify endogenous ferroptosis.
