Article Abstract
Herpetotriol, a typical lignan in Wall's seeds that has long been used to treat icterhepatitis and indigestion and other related diseases in Tibet, is of potential hepatoprotection. This study aims to study the pharmacokinetics features of herpetotriol, including the blood drug concentration - time curve and tissue distribution. The ultrahigh-performance liquid chromatography with tandem mass spectrometry method was established to detect herpetotriol concentration in plasma and tissues, and the method showed good linearity from 10 to 2000 ng/mL ( ≥ 0.9972) and sensitivity (≥10 ng/mL). Our blood drug concentration - time curve indicated that herpetotriol was distributed quickly in rats with a value at about 0.083 h and eliminated rapidly with a clearance rate at 98.13 ± 8.05 and 137.04 ± 9.48 L·h·kg with doses of 5 and 2.5 mg/kg, respectively. Although herpetotriol was detectable in all tested tissues, it has a higher concentration in liver than in heart, lung, spleen, and kidney, which is in line with its hepatoprotection. The pharmacokinetics features uncovered by the present study could provide more information for future pharmacological and toxicological study of herpetotriol.

Epilepsy is a common chronic nervous system disease that threatens human health. However, the role of FOXC1 and its relations with pyroptosis have not been fully studied in epilepsy. Sprague-Dawley rats were obtained for constructing temporal lobe epilepsy (TLE) models.

Accurate modeling of lung parenchymal biomechanics is critical for understanding respiratory function and improving diagnoses. Traditional hyperelastic models capture tissue deformation but miss essential physiological interactions. This study evaluates an experimentally informed poroelastic model (Birzle's formulation) against hyperelastic-only models within a finite element framework.

Covalent organic frameworks (COFs) have been emerging as versatile reticular materials due to their tunable structures and functionalities, enabled by precise molecular engineering at the atomic level. While the integration of multiple components into COFs has substantially expanded their structural complexity, the strategic engineering of diverse functionalities within a single framework the random distribution of linkers with varying lengths remains largely unexplored. Here, we report a series of highly crystalline mixed-length multivariate COFs synthesized using azobenzene and bipyridine as linkers, where tuning the ratio of linkers and incorporating palladium effectively modulates the balance between near-infrared (NIR) light absorption and catalytic sites for NIR-generation of hydrogen peroxide (HO).

Purpose: To objectively quantify, in East Asians and Caucasians, the width and distribution of the retro-orbicularis oculi and frontalis fat (ROOF) pad, subcutaneous fat, and orbicularis oculi muscle (OOM) at the superior orbital rim margin as well as 5 mm superior and inferior to this point.
Methods: Thirty adults were studied by high-resolution, surface coil MRI. In the quasi-sagittal image through the globe center, the ROOF, subcutaneous fat, and OOM thickness were measured anterior to the orbital septum, at 3 points: at the superior orbital rim, and 5 mm superior, and 5 mm inferior to the rim.
