Cadmium (Cd) is an environmental pollutant known to cause liver damage; however, the mechanisms of its hepatotoxicity remain poorly understood. In this study, effects subchronic exposure in mice low doses Cd on energy metabolism and gut microbiome were evaluated. The 10 mg/L supplied drinking water for weeks increased hepatic triacylglycerol (TG), serum free fatty acid (FFA), TG levels. mRNA levels several key genes involved both de novo FFA synthesis transport pathways also significantly...
Hot, dense plasmas exhibit screened Coulomb interactions, resulting from the collective effects of correlated many-particle interactions. In lowest particle correlation order (pair-wise correlations), interaction between charged plasma particles reduces to Debye-Hückel (Yukawa-type) potential, characterized by Debye screening length D. Due importance in laboratory and astrophysical plasmas, hundreds theoretical investigations have been carried out past few decades on electronic structure...
Carbendazim (CBZ) has been considered as an endocrine disruptor that caused mammalian toxicity in different endpoints. Here, we revealed oral administrations with CBZ at 100 and 500 mg/kg body weight for 28 days induced hepatic lipid metabolism disorder which was characterized by significant increases of accumulation triglyceride (TG) levels mice. The serum cholesterol (TC), high-density lipoprotein, low-density lipoprotein also increased after exposure. Correspondingly, the relative mRNA...
Abstract Time-resolved X-ray photoelectron spectroscopy (TXPS) is a well-established technique to probe coherent nuclear wavepacket dynamics using both table-top and free-electron-based ultrafast lasers. Energy resolution, however, becomes compromised for very short pulse duration in the sub-femtosecond range. By resonantly tuning core-excited states undergoing Auger decay, this drawback of TXPS can be mitigated. While resonant Auger-electron (RAS) recover vibrational structures not hidden...

We introduce and demonstrate a new approach to measuring coherent electron wave packets using high-harmonic spectroscopy. By preparing molecule in superposition of electronic states, we show that coherence opens previously unobserved high-harmonic-generation channels connect distinct but coherently related states. Performing the measurements dynamically aligned nitric oxide molecules observe complex temporal evolution under coupling nuclear motion. Choosing weakly allowed transition prepare...

Coulomb-explosion imaging is a broadly employed technique to reconstruct the geometry of molecules from direct multibody breakups its ions. However, we reveal that this fails for large class systems, such as (${\mathrm{CO})}_{2}{}^{3+}$ and ${\mathrm{ArCO}}^{3+}$, since events ``direct breakup channel'' are not real but rapid sequential with short-lived ultrafast-rotational fragment. Using Ar-CO prototype, have investigated theoretically process. We find due interfield between metastable...
