BACKGROUND Epidemic P. aeruginosa (ePA) infections are common in cystic fibrosis (CF) and have been associated with accelerated clinical decline. Factors associated with ePA are unclear, and evidence based infection control interventions are lacking. METHODS We prospectively collect all bacterial pathogens from adult CF patients. We performed PA strain typing on retrospectively collected enro...

Brain eicosapentaenoic acid (EPA) levels are 250- to 300-fold lower than docosahexaenoic acid (DHA), at least partly, because EPA is rapidly β-oxidized and lost from brain phospholipids. Therefore, we examined if β-oxidation was necessary for maintaining low EPA levels by inhibiting β-oxidation with methyl palmoxirate (MEP). Furthermore, because other metabolic differences between DHA and EPA m...

INTRODUCTION The relation between docosahexaenoic (DHA) and eicosapentaenoic (EPA) vs. arachidonic acid (AA) seems characterized by both synergism and antagonism. MATERIALS AND METHODS Investigate the relation between EPA+DHA and AA in populations with a wide range of EPA+DHA status and across the life cycle. EPA+DHA and AA were determined in erythrocytes (RBC; n=1979), umbilical arteries (UA...

Detailed studies were carried out on the effects of nitrogen source, phosphate, sodium chloride, growth factors, precursors, CO2, temperature, initial pH, and inoculum size on biomass and eicosapentaenoic acid (EPA) production by Phaeodactylum tricornutum. The EPA content of total fatty acids increased with increasing concentrations of nitrate and urea. Sodium chloride was not required for grow...
