Sentences with phrase «creating reactive oxygen»

In a third study published online by Science on 6 April (www.sciencexpress.org), molecular geneticist Valter Longo of the University of Southern California in Los Angeles and colleagues battered a population of yeast mutants with heat or paraquat, a chemical that creates reactive oxygen molecules.

More research produced the answer: Vitamin C induced what is known as a Fenton reaction, causing iron to react with other molecules to create reactive oxygen species that kill the TB bacteria.

In earlier versions, the nickel - molybdenum - zinc alloy catalyst used to produce the hydrogen also created reactive oxygen species, which would attack and destroy the bacteria's DNA.

Not exact matches

The cause of the damage is still poorly understood, but radiation is known to create highly reactive oxygen - containing molecules in the body.

Sunlight and toxins do much of the damage, but the biggest culprit may be highly reactive byproducts created as cells use oxygen to turn sugar into energy.

That light is absorbed by the chlorine - based molecules, which then excite nearby oxygen molecules, creating a highly reactive form of oxygen, known as singlet oxygen, that rips apart nearby biomolecules and kills the tumor cell.

The damaged mitochondria become increasingly dysfunctional, producing even more reactive oxygen species and creating an undesirable cycle.

Physiologist Dino Giussani and colleagues at the University of Cambridge in the United Kingdom theorized that hypoxia promotes harm in the womb primarily through stress caused when the low level of oxygen creates an overload of highly reactive molecules known as free radicals.

I've been experimenting with T10 dextran coated iron oxide nanoparticles, obviously not the same as fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high surface area which are largely made from hydroxyl groups, I hypothesised this act's as a «sink» for reactive oxygen species converting them to water.

The addition of this pendant catalyst created an MnP - PVPON / TA capsule with the following characteristics: 1) the microcapsules synergistically remove reactive oxygen species, including superoxide and hydrogen peroxide, at dramatically increased rates compared to unmodified TA / PVPON microcapsules; 2) the microcapsule does not degrade with long exposure to reactive oxygen species; and 3) the microcapsules are nontoxic to mouse splenocytes.

It has been thoroughly researched and shown that the overall health of a body is intrinsically linked to the health of its cells and their ability to metabolize oxidation.5 When oxidative metabolism's limits are exceeded free radicals and reactive oxygen species (ROS) are created and start to build up within the body.

But 0.5 to 5 percent of the time, reactive oxygen species (ROS) are created.

This causes the body to create unstable molecules known as reactive oxygen species (ROS).

But the process of producing ATP creates a huge burst of damaging free radicals known as reactive oxygen species (ROS), which are the chief cause of mitochondria destruction.

The damage may cause mutations to the DNA, possibly creating a GREATER NUMBER of Reactive Oxygen Species.

When your body is able to burn fat for fuel, your liver creates water - soluble fats called ketones that burn far more efficiently than carbs, thereby creating fewer reactive oxygen species (ROS) and secondary free radicals.

As congestive heart failure progresses, the formation of «free radicals» (reactive molecules created during oxygen metabolism) increases heart cell damage.

Global warming is implicated in the loss of Arctic ozone because greenhouse gases trap energy lower down, heating up the atmosphere nearer the ground but cooling the stratosphere, creating conditions conducive to the formation of the reactive chemicals that break apart the three - oxygen molecules of ozone.
