It is important to realise that an acre can be measured in any shape - from rectangles to circles or even hexagons - so long as the total area of land is 43,560 square feet. The most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet. If you're struggling to get your head around just how big that area actually is, try visualising 60% of a soccer pitch, 75% of an American football field or 16 tennis courts in a 4x4 formation. If that doesn't help, consider a car park containing 150 cars parked in a square.
Introduction. Aspirin is an antiplatelet medicine, which means it reduces the risk of clots forming in your blood. This reduces your risk of having a stroke or heart attack. Normally, when there is a cut or break in a small blood vessel, a blood clot forms to plug the hole until the blood vessel heals.
Therefore, after treatment with aspirin is stopped, cyclooxygenase activity recovers slowly, as a function of platelet turnover22,30. This explains the apparent paradox of how a drug with a 20-minute half-life in the systemic circulation can be fully effective as an antiplatelet agent when administered once daily.
