Sentences with phrase «when reactive oxygen»

Not exact matches

When potent oxygen radical scavengers such as cerium oxide nanoparticles (nanoceria) were combined with a highly charged polymer (polyacrylic acid) and incorporated into extracted chloroplasts using the LEEP process, damage to the chloroplasts from superoxides and other reactive oxygen species was dramatically reduced.

The immune system may kick in when animals eat, releasing reactive oxygen molecules to kill microbes on food, helping to protect from disease.

But when the lights go on, TAPP becomes active, producing chemicals called reactive oxygen species, or ROS, that rapidly kill the bacteria.

This fact makes vacuum UV light extremely useful for industrial applications from sterilizing medical devices to cleaning semiconductor substrates because when it strikes oxygen - containing molecules on a surface, it generates highly reactive oxygen radicals, which can completely destroy any microbes contaminating that surface.

Although reactive oxygen species can damage cells when produced in high amounts, according to a study published online Sept. 5, 2017 by Science Signaling and featured on the journal's cover, these oxidative species are crucial signals that start the process of repairing myofiber.

«Our work highlights the need to take a nuanced view of the role of reactive oxygen species, as they are necessary when they are present at the right place and right time.

When O3 interacts with a metal oxide (Mn / TiO2), O3 is decomposed by the following reactivity formula on the surface of manganese, generating reactive oxygen species, i.e., oxygen radical.

This is a key component of the immune system, when the body releases reactive oxygen species to fight against invading bacteria.

That phenomenon, known as oxidative stress, occurs when the cells of older adults begin to produce too much superoxide and other reactive oxygen species.

When academic allergist Sanjiv Sur at the University of Texas in Galveston and colleagues exposed mice to ragweed pollen, they noticed the animals produced highly - reactive forms of oxygen in their lungs after 15 minutes.

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.

This symptom results from accumulation of porphyrins, tetrapyrrole intermediates in heme biosynthesis that generate reactive oxygen species when exposed to light, in the skin of affected individuals.

Itâ $ ™ s not a silly question, when one sees how oxidative stress and reactive oxygen species have been implicated in so many diseases, ranging from hypertension and atherosclerosis to neurodegenerative disorders.

So while it's true that organisms living deep in the Earth are not exposed to the high - energy radiation found when you travel between planets or more hypothetically between stars, the systems that cells have evolved to repair damage done by reactive oxygen species will be useful whether they arise from rocks or from cosmic rays.

This primary response involves the production of reactive oxygen species (ROS), which are molecules that can act like tiny bombs when released by the plant cell at the offending pathogen.

According to Tuveson, «it turns out the scaredy cat in this whole situation is the cancer cell, which can not deal with reactive oxygen and really waves the white flag when you raise reactive oxygen.»

Also well established is the fact that the glutathione antioxidant system is the most important system in our bodies (Meister, 1994) when it comes to the destruction of reactive oxygen compounds (very potent free radicals).

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.

As a general rule, the shorter the carbon chain, the more efficiently the MCT will be turned into ketones, which are an excellent source of energy for your body — far preferable to glucose, as ketones produce far less reactive oxygen species (ROS) when they are metabolized to produce ATP.

Known as «delayed onset muscle soreness» (DOMS), we typically experience these pains when eccentric muscle activity is involved and the contracting muscles are forcibly lengthened.1 This mechanical stress triggers an inflammatory response and the production of reactive oxygen species (ROS).

Generation of reactive oxygen species, or free radicals such as superoxide and hydrogen peroxide, is a normal byproduct of metabolism, but can damage cellular machinery when excessive and impair the production of cellular energy, which becomes a vicious cycle as energy - intensive repair processes become untenable (25, 26).

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.
