Abstract: Techniques are provided for gathering statistics in a database system. The techniques involve gathering some statistics using an “on-the-fly” technique, some statistics through a “high-frequency” technique, and yet other statistics using a “prediction” technique. The technique used to gather each statistic is based, at least in part, on the overhead required to gather the statistic. For example, low-overhead statistics may be gathered “on-the-fly” using the same process that is performing the operation that affects the statistic, while statistics whose gathering incurs greater overhead may be gathered in the background, while the database is live, using the high-frequency technique. The prediction technique may be used for relatively-high overhead statistics that can be predicted based on historical data and the current value of predictor statistics.

Abstract: Provided are a method, target and application for NO accumulation to decrease invasiveness of Pseudomonas aeruginosa; achieving NO accumulation by means of external NO donors or disruption of internal NO metabolism in an environment where Pseudomonas aeruginosa is growing or being cultured, in order to decrease production by Pseudomonas aeruginosa of the invasion factor pyocyanin. Utilizing even micro-quantities of NO can significantly inhibit Pseudomonas aeruginosa PCN (PCN synthesis down 82% with 60 ?M SNP treatment); by inhibiting NO reductase, an enzyme related to NO metabolism, PCN synthesis can be significantly inhibited (the PAO1-?nor strain has 84% PCN reduction). Using NO donors or inhibiting enzymes involved in Pseudomonas aeruginosa NO metabolism as a means of combating bacterial infectious disease does not affect the body's normal microflora like traditional antibiotics.
