For example, some research suggests that NO administered to a patient after a stroke helps the patient, while other research suggests that excess NO produced during strokes damages brain cells. Thank you for sharing! Our other type of immunity is the acquired immune response, which involves an attack that is specific for each pathogen. Three researchers—Robert F. Furchgott, Louis J. Ignarro, and Ferid Murad—discovered that NO acts as a signaling molecule in the circulatory system. Researchers need to learn more about nitric oxide's effects on the body before it's widely used medicinally. Without NO, the donated blood may block the circulatory system because it can't move through the vessels properly. Mary Hyatt from Florida on February 22, 2013: Very interesting and informative Hub. Thanks for the visit. It also functions as a messenger in the cardiovascular and immune systems. Macrophages and nitric oxide action are part of our innate immune response. Nitric oxide is a powerful neurotransmitter that helps blood vessels relax and also improves circulation. If NO is administered to treat one health problem, it's important that it doesn't cause another one. This allows more blood to flow into the heart and other organs. Cheers :-). It also functions as a messenger in the cardiovascular and immune systems. It isn't produced in advance or stored but is made when it's needed. An important intermediate in industrial chemistry, nitric oxide forms in combustion systems and can be generated by light As a matter of fact, these products can have a significant impact on your sexual health. Thanks for the visit, Jimmy. Nitric oxide is a vasodilator, which means it promotes effective blood flow by relaxing the inner muscles of your blood vessels. One research experiment discovered that C. elegans worms fed normal B. subtilis lived for 15 percent longer than those fed a mutant form of the bacterium that lacked the gene for nitric oxide production. 2. More studies are needed to clarify the situation. That required finding a suitable catalyst material that could generate nitric oxide from a benign precursor material. I appreciate your comment, as well as the votes and the share! Nitric oxide (NO) is a compound produced naturally in the body. It's an interesting substance that can be a friend or a foe.

By further doping these nanoparticles with platinum, the team was able to enhance their electrocatalytic efficiency. If pregnant or nursing, consult with a qualified provider on an individual basis. Green vegetables such as romanesco broccoli contain nitrates. Nitric oxide is a type of molecule, an oxide of nitrogen, that plays a critical role in blood health within the body. In addition, it plays an important role in our immune system and helps it to fight infections. If a doctor thinks that supplement arginine will be useful for a patient’s specific medical problem and that the possible side effects of the supplement won’t be harmful to that patient, they’ll recommend a safe and potentially beneficial dose. Produced by the body in small amounts where it is needed, it is essential and helps maintain health. Guess we folks just never think of nitric oxide in our bodies. Simulations rule out plasmas caused by meteoroid impacts as the source of lunar magnetism, supporting the proposal that the ancient moon generated a core dynamo. Nitric oxide is a colorless gas with the formula NO. Leafy green vegetables are so healthy - I'm glad that I like them! The medication comes in additional forms besides a swallowed version. Nitric oxide determines a lot many functions in our body primarily the cardiovascular function as it helps regulate normal blood pressure by ensuring sufficient circulation. JCielo from England on February 24, 2013: Well researched and very well presented. You can be so local and so modular with an electrochemical process that you can even do this at the level of the cell,” Manthiram says. 1. … The nitric oxide made from the nitroglycerin is responsible for the vasodilation. It also functions as a messenger in the cardiovascular and immune systems. Drugs, supplements, and natural remedies may have dangerous side effects. When a nerve impulse arrives at a synapse, the neurotransmitter is released from the first neuron into the tiny gap that is present between neurons. I love broccoli and am so glad to hear of this additional health benefit. Keywords: arginase, nitric oxide, citrulline, arginine, diabetes, vascular function. Escherichia coli can't make nitric oxide, however. Basically, your body … Guess I should not say NO to adding more cabbage, beets and broccoli to my diet. below, credit the images to "MIT.". Yes? Nitric oxide also plays an important role in T-cell mediated diseases of the skin, and it has both pro and anti-apoptotic properties depending on its concentration, cell type, and availability of other substrates. Deb Hirt from Stillwater, OK on February 20, 2013: So nitric oxide introduced into out bodies will help us sleep better, vs. wasting money on sleeping aids, I trust? prasetio30 from malang-indonesia on February 19, 2013: Very informative and useful for us.
