A single AFMK molecule can neutralize up to 10 ROS / RNS ( reactive oxygen species / reactive nitrogen species ) since many of the products of the reaction / derivatives ( including melatonin ) are themselves antioxidants.

FCC rulings on the new soundcard mode called ROS point to the need to drop regulations that hinder experimentation and impede the development of narrowband techniques on the bands where they are most needed

These two enzymes are both involved in either triggering or detoxifying ROS.

It is suggested that the antimutagenic properties of PRP are achieved via multiple mechanisms-by decreasing intracellular levels of ROS and so preventing DNA damage and by increasing the efficiency of natural DNA repair mechanisms.

There are several ROS including: superoxide, hydrogen peroxide and hydroxyl, all of which lead to neurotoxicity.

However, this breakdown of the ROS is not completely efficient ; some reactive residues are left in the brain to accumulate, contributing to neurotoxicity and cell death.

Because neurons are characterized as postmitotic cells, meaning that they live with accumulated damage over the years, accumulation of ROS is fatal.

Oxidation by either COX or lipoxygenase releases reactive oxygen species ( ROS ) and the initial products in eicosanoid generation are themselves highly reactive peroxides.

Reactive oxygen species ( ROS ) are chemically reactive molecules containing oxygen.

ROS are also generated by exogenous sources such as ionizing radiation.

Effects of ROS on cell metabolism are well documented in a variety of species.

In addition to energy, reactive oxygen species ( ROS ) with the potential to cause cellular damage are produced.

ROS are produced as a normal product of cellular metabolism.

While ROS are produced as a product of normal cellular functioning, excessive amounts can cause deleterious effects.

The most notable initiators in living cells are reactive oxygen species ( ROS ), such as OH · and HO2, which combines with a hydrogen atom to make water and a fatty acid radical.

The resulting ratio is return on sales ( ROS ), the percentage of sales revenue that gets ' returned ' to the company as net profits after all the related costs of the activity are deducted.

Prior, in vitro studies have shown that reactive oxygen species ( ROS ) are involved in AO induced toxicity causing peroxidative damage of lipids in various hepatic sub-cellular fractions including microsomes and mitochondria of rats.

Modulation of ROS levels, inhibition of topoisomerases I and II, reduction of NFkappaB and AP-1 activity, stabilization of p53, and inhibition of PI3K, STAT3, IGF1R, and HER2 are possible mechanisms involved in the putative biological activities of luteolin.

A variety of reactive oxygen species or " ROS " ( namely H < sub > 2 </ sub > O < sub > 2 </ sub >, but also superoxide, singlet oxygen and radical hydroxyl ) are generated by plants during times of stress ( biotic and abiotic ) including UV light, cool temperatures, excessive light, pathogens, parasites, and high salinity.

ROS and free radicals are implicated in DNA damage, cancer, accelerated cell aging.

For example, it has been found to interact with NADPH cytochrome P450 reductase, associated with increased production of ROS, and glutathione S-transferase, responsible for production of the anti-oxidant glutathione.

Significantly, ROS does not account for the capital ( investment ) used to generate the profit.

* ROS or RAS, for Required On / At Site, a way to state the date when a deliverable is required on a construction site

It is headed by a director and with an assistant director and six ( 6 ) deputy-directors for — Special Investigation Services ( SIS ); Regional Operations Services ( ROS ); Intelligence Services ( IS ); Technical Services ( TS ); Administrative Services ( AS ); and Comptroller Services ( CS ).

The number 767 corresponds to the letters ROS and may be mnemonic for Roseau, Dominica's capital city.

ROS is estimated to be used by 60 % of all taxpayers and over 80 % of tax agents.

The Revenue On-Line Service ( ROS ), is a pioneer in European internet applications, and it is run by Revenue in the Republic of Ireland.

Naturally, the body utilizes a defensive mechanism to diminish the fatal effects of the reactive species by employing certain enzymes to break down the ROS into small, benign molecules of simple oxygen and water.

Cellular necrosis can be induced by a number of external sources, including injury, infection, cancer, infarction, poisons, ROS ( Reactive Oxygen Species ), and inflammation.

Outside the territorial organisation, the Specialist Mobile Unit Command Palidoro ( based in Rome ) controls the Mobile Unit Division, the Specialist Unit Division and the ROS.

The ROS ( Raggruppamento Operativo Speciale or Special Operational Group ) is an elite unit founded in 1990 to deal with organised crime ( Mafia and others ), subversive activities, terrorism and more complex types of crime.

Chemi-excitation via oxidative stress by reactive oxygen species ( ROS ) and / or catalysis by enzymes ( i. e. peroxidase, lipoxygenase ) is a common event in the biomolecular milieu.

It also functions as signal transducer / integrator to regulate MAPK pathway, ROS, as well as intracellular calcium.

The downstream signals through ouabain-triggered protein phosphorylation events include to activate the mitogen-activated protein kinase ( MAPK ) signal cascades, mitochondrial reactive oxygen species ( ROS ) production, as well as activation of phospholipase C ( PLC ) and inositol triphosphate ( IP3 ) receptor ( IP3R ) in different intracellular compartments.

Hypoxia also causes reactive oxygen species ( ROS ) production that can activate HIF-1, EGR-1, and nuclear factor-κB ( NF-κB ), which regulates HIF-1 transcription.

It also has been found to be effective in protecting against brain injury caused by ROS release in experimental hypoxic brain damage in newborn rats.

This study concludes that " determining what, if any, type of damage is done by ROS generated by UV filters needs to be explored.

Since the rate of oxygen consumption is particularly high in brain tissues, production of reactive oxygen species ( ROS ) is accentuated in these vital cells, making them particularly vulnerable to oxidative damage and especially dependent upon the antioxidant protection provided by selenoenzymes.

Indeed, this protein interacts with cytochrome P450 2E1 suggesting a possible role in detoxifying cytochrome ROS, produced readily by the members of this superfamily36.

Thus it is readily seen that FA proteins also act outside of the Fanconi pathway, either by helping neutralize ROS or by taking part in DNA repair.

Furthermore, it is known that cross-linking agents produce ROS and it is possible that FA cell hypersensitivity to cross-linkers is not due directly to them, but rather to the cell ’ s impaired ability to cope with increased ROS production.

Bacteria, inflammation, nutrition and ROS ( reactive oxygen species ) may all play a role in arterial disease.

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

The excess T < sub > β </ sub > and T < sub > γ </ sub > have been concluded to be floating freely around in the ROS, though it cannot be associated with the T < sub > α </ sub > at any given time.

When infused into human blood, ozone produces reactive oxygen species ( ROS ) or free radicals, an over-abundance of which is known to cause oxidative stress and cell damage, and is implicated in the progression of some degenerative diseases.
