Doubleand triple bonds between atoms are usually made up of a single sigma bond and one or two pi bonds. Pi bonds are generally denoted by the Greek letter π, in reference to the p orbital. The symmetry of a pi bond is the same as that of the p orbital as viewed down the bond a...

Antibiotic treatment failure in Pseudomonas aeruginosa chronic lung infections is associated with increased morbidity and mortality, illustrating the clinical challenge of bacterial infection control. Understanding the underlying infection environment, as well as the host and bacterial factors driving antibiotic ...
ATP (sodium salt, Sigma) was applied via a U-tube perfusion system for 3 s at 3–5 minute intervals to allow reproducible responses to be recorded. For determination of antagonist sensitivity AZ10606120 (Tocris) was bath perfused as well as co-applied with ATP through the U-tube. To...
After growth, the periplasmic fractions containing the soluble recombinant XcpGp and XcpHp proteins were obtained from osmotically shocked bacteria and dialyzed overnight at 4°C in dialysis tubing (Sigma) against buffer (50 mM sodium phosphate buffer pH 7, 150 mM NaCl). In vitro cysteine cross...
