Original article: Efficacy and safety of single-dose suraxavir marboxil tablet in the treatment of acute uncomplicated influenza in adults: a multi-center, randomized, double-blind, placebo-controlled phase 2 clinical trial.

Objectives: To evaluate the therapeutic effect of suraxavir marboxil (GP681, abbreviated as suraxavir) in adults with uncomplicated influenza.

Methods: We conducted a multi-center randomized, double-blind, placebo-controlled phase 2 trial in 18 Chinese centers. Participants had to be aged 18-65 years with positive influenza test, presenting with at least one influenza systemic and respiratory symptoms in at least moderate severity within 48 hours of onset.

Long-term antibody trajectories after PPSV23 in elderly: Results from a 4-year follow-up study.

Background: The 23-valent pneumococcal polysaccharide vaccine (PPSV23) is recommended for standalone or sequential use in the elderly in many countries to prevent pneumococcal disease, making it crucial to assess vaccine response and long-term persistence.

Purpose: We aimed to describe the trajectories of circulating antibody levels to the PPSV23 in the elderly following immunization.

Methods: Eligible individuals aged 65 to 70 years were enrolled and vaccinated with one dose of PPSV23.

Complete Mitochondrial Genomes of and with Phylogenetic Analysis of Charadriiformes.

Background: Plovers (Charadriidae), within the order of Charadriiformes, a group of modern birds distributed worldwide, are a frequent subject of molecular phylogenetic studies. While research on mitochondrial genome (mitogenome) variation within the family Charadriidae, especially intraspecific variation, is limited. Additionally, the monophyly of and the phylogenetic placement of remain contentious.
