Objective: The objective of this study was to investigate the association between sarcopenia and liver fibrosis in patients aged 18-59 years with metabolic dysfunction-associated steatotic liver disease (MASLD) and to assess the potential of sarcopenia as a risk factor for the progression of liver fibrosis.
Methods: The study included 821 patients with MASLD in the US cohort and 3,405 patients with MASLD in the Chinese cohort. Liver controlled attenuation parameters (CAP) and liver stiffness measurements (LSM) were assessed by vibration-controlled transient elastography (VCTE) to evaluate the extent of hepatic steatosis and fibrosis.
Guided-VCTE: An Enhanced FibroScan Examination With Improved Guidance and Applicability.

Objective: Although FibroScan (FS), based on Vibration-Controlled Transient Elastography (VCTE), is a widely used non-invasive device for assessing liver fibrosis and steatosis, its current standard-VCTE examination remains timely and difficult on patients with obesity. The Guided-VCTE examination uses continuous shear waves to locate the liver by providing a real-time predictive indicator for shear wave propagation and uses shear wave maps averaging to increase the signal-to-noise ratio in difficult to assess patients. We aimed to evaluate the effectiveness of the new indicator, as well as compare examination times and success rates with both standard-VCTE and Guided-VCTE examinations.

In this study, the need for efficient detection of volatile organic compounds (VOCs) in environmental monitoring, industrial safety, is addressed by investigating borophene-based B36 nanoclusters as gas sensors. Density functional theory (DFT) calculations were employed to examine the adsorption behavior of ethanol, isobutanol, and acetone on B surfaces, with a focus on vibrational modes, reactivity, and adsorption energies. It was found that acetone exhibits the strongest interaction with pristine B, indicating its potential for robust sensing applications.

Constructing multifunctional phosphors grounded in the intricate relationship between energy level structures and luminescent properties has captivated researchers in the luminescent material field. Herein, using the embedded cluster multiconfigurational ab initio method, the energy levels of Bi in the SrLaGaO host at different geometries were calculated, which results in the establishment of complete configurational coordinate curves, yielding breathing mode vibrational frequencies and equilibrium bond lengths for all excited states. These curves supply deep insight into the luminescence properties of Bi-doped phosphors and highlight the impact of ions in the second coordination sphere on luminescence.

Controlling vibrational modes and energy gap by creating van der Waals (vdW) heterostructures through strain engineering is a novel approach to tailor the vibrational and electronic properties of two-dimensional (2D) materials. Numerous theoretical and experimental studies have significantly contributed to analysing the properties of transition metal dichalcogenides (TMDs), known for their multifunctional applications. In this study, we investigate the strain and stacking dependent vibrational properties of WSe2/MoSe2 and MoSe2/WSe2/MoSe2 vdW heterostructures using first-principles based density functional theory calculations.
