But they only reduce ROS enough to keep the cells from dying.

There is some great ROS stuff on this site.

Several enzymes have been shown to be involved in generation of ROS.

Field experience quickly shows that potential ROS will usually vary across a complex terrain.

A fire starting from a line greater than 100 m long will burn at its potential ROS immediately.

And then ROS begins to damage genes, making the cancer even more aggressive.

However, increased oxygen levels also means increased production of ROS.

Likewise a factor such as ROS may underlie more than one condition.

The human body implements an antioxidant defense system to protect against ROS.

By using the ROS, the transfer decreased but the operation margin could be increased.

A number of mutagens may also generate these ROS.

They suggest ROS signalling may be a determinant in the aging process.

(ROS starts to protest but he had hardly opened his mouth before:)

(ROS approaches him brightly, holding a coin between finger and thumb.

These excess electrons pass to oxygen and form ROS.

This process reduces ROS damage to a reasonable amount, therefore increasing longevity.

Currently its only available for Hydro or lower version of ROS.

Fuel load is a critical input to ROS equations.

Because of their role in metabolism, mitochondria are very susceptible to ROS damage.

Operating margins for the rest of the industry are now 3 percent.

For now, the company's operating margins are less than the industry average.

A higher operating margin means that the company has less financial risk.

By contrast, Sprint's local operations had a 27.1 percent operating margin.

There were numerous corporations whose only concern was to maintain their operating margin.

"Revenues from these product lines represented almost no growth, and operating margins below the average of the company," he said.

The company's operating margin was 37 percent, compared with 35 percent in the period a year earlier.

Analysts calculate that operating margins on supplies are about 25 percent.
