Platelet Aggregation in Apparently Healthy Elderly Populations: Reference Ranges and Influence of Hematology Parameters.

Background: Reference intervals based on younger populations may not apply to elderly populations. The aim of the current study was to calculate reference ranges for platelet aggregation in apparently healthy Chinese elderly populations and analyze the impact of gender, age, and hematological parameters on platelet aggregation in vitro.

Methods: A total of 138 males and 161 females were enrolled based on stringent inclusion and exclusion criteria.

Biofilm formation in Acinetobacter baumannii was inhibited by PAβN while it had no association with antibiotic resistance.

This study was conducted to investigate the relationship between Acinetobacter baumannii biofilm formation and antibiotic resistance. Furthermore, the effects of PAβN, a potential efflux pump inhibitor, on A. baumannii biofilm formation and dispersion were tested, and the gene expression levels of efflux pumps were determined to study the mechanisms.
