Sex differences in lipid mediators derived from omega-3 fatty acids in older individuals with low-grade chronic inflammation.

The rate of cardiovascular disease (CVD) death is higher in men than women before age 50 y, but the gap between sexes significantly narrows after menopause. Lipid mediators derived from EPA, DHA and AA play a role in inflammation and CVD. The aim of our study was to assess whether plasma concentrations of these lipid mediators differ between postmenopausal women and men.

High Transcriptional Activity and Clinical Correlations in Eosinophils of Patients with Late-Onset Asthma.

Background: The immunological features of eosinophils in early-onset asthma (EOA) differ from those in late-onset asthma (LOA). Clinical trials of anti-interleukin-5 (IL-5) treatment for severe eosinophilic asthma showed a better response for LOA patients than EOA patients. We wonder if the transcriptional activity of activated eosinophils was different in EOA and LOA.
