Protective effect of trans-nerolidol on vascular endothelial cell injury induced by lipopolysaccharides

This article aimed to discuss the protection of trans - nerolidol on vascular endothelial cells (ECs) injured by lipopolysac charides. ECs were divided into four groups: normal, model, low and high dose trans - nerolidol treatment groups. The cell survival rate and th...

Histological and Ultrastructural Changes in Lungs One Year Post Asymptomatic or Mild SARS-CoV-2 Infection: Evaluating the Potential for Active Virus Presence

Int. j. morphol; 42 (3), 2024
SUMMARY: Prior research on post-COVID-19 or long COVID primarily focused on the presence of SARS-CoV-2 mostly in symptomatic patients. This study aimed to investigate the persistence of SARS-CoV-2 after 1 year of asymptomatic or mild COVID-19. SARS-CoV-2 infected and control K18-hACE2 transgenic mice (n=...
