Background: The efficacy of dexmedetomidine (DEX) in treating sepsis-induced myocardial injury (SIMI) remains unclear. In this study, we explored the relationship between DEX use and clinical outcomes of patients with SIMI, focusing on the dosage and treatment duration.
Methods: In this retrospective cohort analysis, we identified patients with SIMI from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database and categorized them into the DEX and non-DEX groups based on intensive care unit treatment.
Background And Purpose: Parkinson disease (PD) is defined by its unique motor symptoms, where responsiveness to levodopa (L-DOPA) is fundamental for management. Recent research has highlighted a significant relationship between PD symptoms and glymphatic dysfunction. This study endeavors to clarify the connection between glymphatic system functionality and initial motor symptoms in PD, utilizing imaging biomarkers to determine its predictive capacity for L-DOPA responsiveness (LR).

In this work, to address the deficiency that sesquiterpene lactone containing α-methylene-γ-lactone moiety was rapidly metabolized by endogenous nucleophiles, series of novel thioether derivatives were designed and synthesized based on a reactive oxygen species (ROS)-triggered prodrug strategy. Among them, prodrug exhibited potent cytotoxicity against NSCLC cells and better release rates in response to ROS.

Nonetheless, their similar physical properties make them difficult to distinguish. The present study developed fast and efficient rules for identifying the esterification sites of 20-deoxyingenol based on a series of chemical syntheses of monoesters and literature research, utilizing NMR spectroscopy, optical rotation analysis, and chromatographic retention behavior.
