Sentences with phrase «including oxygen radicals»

Not exact matches

Different factors, including the free radicals that are a byproduct of oxygen metabolism, result in Top1ccs becoming trapped on DNA and accumulating in cells.

They pack a powerful punch to fight free radicals (highly reactive forms of oxygen that can destroy cell membranes, and other structures including DNA and collagen).

They are formed naturally through normal metabolic processes; however more sources of free radicals include poor food choices, certain prescription medications, environmental pollution, tobacco smoking (including second - hand), stress, ultraviolet light, oxygen and radiation.

Energy metabolism and the production of Reactive Oxygen Species (very small molecules that can result in significant damage to cell structures, of which include oxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these condiOxygen Species (very small molecules that can result in significant damage to cell structures, of which include oxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these condioxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these conditions.

While there are many types of free radicals that can be formed, the most common in aerobic (oxygen breathing) organisms are oxygen free radicals, often referred to as Reactive Oxygen Species (ROS), which include superoxides, hydroxyl anions, hydrogen peroxide and singlet oxygen.&oxygen breathing) organisms are oxygen free radicals, often referred to as Reactive Oxygen Species (ROS), which include superoxides, hydroxyl anions, hydrogen peroxide and singlet oxygen.&oxygen free radicals, often referred to as Reactive Oxygen Species (ROS), which include superoxides, hydroxyl anions, hydrogen peroxide and singlet oxygen.&Oxygen Species (ROS), which include superoxides, hydroxyl anions, hydrogen peroxide and singlet oxygen.&oxygen.»

It is a cofactor in several oxidative enzymes vital to the function of hematopoietic, vascular and skeletal tissues, as well as the structure and function of the nervous system, including superoxide dismutase (oxygen radical scavenger), cytochrome - c oxidase (mitochondrial respiration), lysyl oxidase (collagen and elastin synthesis) and ceruloplasmin ferroxidase / haephestin (iron metabolism).

Oxidative stress describes the state of the body in which the production of reactive oxygen species (ROS), including free radicals, overwhelms the body's antioxidant defences.Our body tries to maintain a constant balance between free radicals and antioxidants.

It has been tested under laboratory conditions for effectiveness against a variety of free radicals, including singlet oxygen, super-oxide, and hydroxyl radicals.

Flavonoids are powerful antioxidants and are believed to help the body's cells resist damage by free radicals, which are formed by numerous processes including when the body's cells utilize oxygen for energy.

Using a lab testing procedure called ORAC (Oxygen Radical Absorbance Capacity), USDA researcher Ronald Prior, Ph.D., found that a one - cup serving of Wild Blueberries has more total antioxidant capacity (TAC) than 20 other fruits and veggies, including cranberries, strawberries, plums, raspberries and even cultivated blueberries.

On the ORAC scale (oxygen radical absorbance capacity — a measure of the antioxidant capacity of food), it surpasses all other antioxidant - rich foods including blueberries, pomegranates, and dark chocolate.

The therapeutic dotential of dietary precursor modulation by a fish - oil - supplemented diet (n - 3 fatty acids), such as eicosapentaenoic acid (C20: 5,n - 3) and docosahexaenoic acid (C22: 6,n - 3) in the therapy of ulcerative colitis has been shown to result in a 35 % to 50 % decrease in neutrophil production of LTB4.28 Significant improvement in symptoms and histologic appearance of the rectal mucosa has been observed in several small series of patients with Crohn's disease and ulcerative colitis given fish oil at 3 to 4 g daily for 2 to 6 months in uncontrolled studies.29 However, a larger, randomized, double - blind trial comprising 96 patients with ulcerative colitis failed to reveal any benefit in remission maintenance or treatment of relapse on 4.5 g of eicosapentaenoic acid daily, despite a significant reduction in LTB4 synthesis by blood peripheral polymorphonuclear cells.30 It should be emphasized, however, that the anti-inflammatory actions of the fish oils, in addition to inhibition of LTB4, include suppression of IL - 1 and platelet activating factor synthesis and scavenging of free oxygen radicals.30 The impact of increased lipid peroxidation after fish oil supplementation should be considered when altering the n - 6: n - 3 fatty acid ratio.31 Antioxidant supplementation may be able to counteract the potentially adverse effects of n - 3 fatty acids.
