In a crude oil contract, a one-cent move is equal to $10. When determining NYMEX's crude oil profit and loss figures, you calculate the difference between the contract price and the exit price, and then multiply the result by $10.
The hypothesis is that strict fluid restriction leads to a larger increase in plasma sodium than standard treatment in patients with decompensated heart failure associated with hyponatremia. A secondary hypothesis is that the neurohormonal change is greater in patients treated with strict fluid restriction versus standard treatment.
If the concentration of sodium is too high in the bloodstream, water will leak from cells into the blood stream to try to dilute and lower the sodium concentration. Conversely, if sodium levels in the bloodstream are too low, water will leave the blood and enter cells, causing them to swell. Hyponatremia is the term used to describe low sodium levels in the bloodstream (hypo=low + natr=sodium + emia=blood).
