Comprehensive Investigation of Sweroside Metabolism in Rats Using a De Novo Strategy Based on Ultra-High-Performance Liquid Chromatography/Quadrupole-Exactive Mass Spectrometry.

Sweroside, a natural secoiridoid glycoside derived from various medicinal plants, is known for its anti-tumor, anti-inflammatory, and hepatoprotective properties. However, its pharmacological significance is not fully supported by its low systemic exposure. In this study, a de novo strategy was proposed to investigate the metabolism of sweroside in rats, including drug administration, sample pretreatment, ultra-high-performance liquid chromatography/Quadrupole-Exactive mass spectrometry data acquisition, data processing, and semi-quantitative analysis.

Optimal frailty assessment tool for elderly patients with heart failure based on outcome prediction: protocol for a multicentre prospective cohort study.

Introduction: Frailty significantly influences the prognosis of elderly patients diagnosed with heart failure. The assessment of frailty is a critical initial step in the management of these patients, as a systematic and precise evaluation facilitates the identification of individuals at high risk. This identification enables timely and targeted interventions, which can subsequently reduce the likelihood of adverse cardiovascular events and improve the quality of life for elderly patients with heart failure.

Critical considerations for co-administering rivaroxaban and vonoprazan: Unveiling potential pharmacokinetic interactions.

To study the effects of metabolic enzyme activity inhibition and genetic polymorphisms on the pharmacokinetics and pharmacodynamics of rivaroxaban, we established an in vitro enzymatic reaction system to screen for inhibitors, and used the UPLC-MS/MS method to detect the levels of rivaroxaban and its metabolite M2-1. Additionally, in vivo pharmacokinetic-pharmacodynamic studies were conducted using Sprague-Dawley rats. Human recombinant CYP2J2 baculosomes were prepared using a baculovirus-insect expression system to investigate the impact of genetic polymorphisms on rivaroxaban metabolism through enzyme kinetics methods.

Aims: To assess the efficacy and safety of cofrogliptin for impaired glucose tolerance (IGT).

Methods: In this multicenter, double-blind, placebo-controlled phase 2 trial, IGT patients were randomized 1:1:1 to receive cofrogliptin 10 mg, cofrogliptin 25 mg or placebo once biweekly. The primary endpoint was the change from baseline in glucose total AUC during meal tolerance test (MTT) at week 12.

MoS-Based NH Sensor for In Situ Detection.

Detection of is essential for the prevention of gastric cancer. By detecting the metabolized NH, it was able to noninvasively reveal the state of ; however, it is still a challenge since the metabolized NH concentration is much lower for conventional gas sensors. Herein, we developed a MoS-based NH sensor for continuous, real-time monitoring of growth.

Potential impact of organophosphate esters on thyroid eye disease based on machine learning and molecular docking.

Organophosphate esters (OPEs) are widely used as flame retardants and plasticizers in daily commodities and building materials. Some OPEs, acting as agonists of the thyroid-stimulating hormone receptor (TSHR), may contribute to the development of thyroid eye disease (TED). This study analyzes the serum and urine of patients and control groups, using machine learning and molecular docking to investigate the potential impact of OPEs on TED.
