    Nitric oxide is a naturally occurring molecule that has many biological and industrial functions. The molecule is made up of one nitrogen atom and one oxygen atom. It is considered a free radical, which means it has unpaired valence electrons, making it highly chemically reactive. It is not a very popular molecule in terms of how many people know what it is used for, but it has many subtle, important uses. Because nitric oxide is a naturally occurring molecule, it has been around since the beginning

    free radical nitric oxide is an abundant intracellular messenger molecule that plays a central role in maintenance of health, and is heavily involved in signal transduction in various cells of the body [1]. This molecule acts as a mediator in the regulation of cardiac function as well as having an important role in regulating contractility of the heart and maintenance of vascular tone in the cardiovascular system. As one of the most significant individuals in our discovery of nitric oxide, Dr. Robert

    Nitric Oxide (NO) and the Nervous System Better known as an environmental hazard, nitric oxide (NO) is produced in combustion engines and contributes to smog and acid rain and has been implicated in the catalytic destruction of the ozone layer (Lancaster;1992). Though NO is the bad-boy of the environment, it’s roles in the body are extremely diverse and in some instances can be deleterious or beneficial depending on the circumstances. NO has been connected with immune function, control of blood

    scientists for their contribution to the discovery of nitric oxide (NO) as a physiological singling molecule, particularly in vascular smooth muscle: Dr. Robert F. Furchgott, Dr. Louis J. Ignarro, and Dr. Ferid Murad1,2. Although the Prize was only initially awarded to Furchgott and Murad, it was later admitted that without the work of Ignarro an important link would not have been made. More specifically, in 1977 Murad found that nitric oxide was the active molecule causing vasodilation when studying

    Expansion on the Recent Discoveries Concerning Nitric Oxide as presented by Dr. Jack R. Lancaster Nitric Oxide, or NO, its chemical representation, was until recently not considered to be of any benefit to the life processes of animals, much less human beings. However, studies have proven that this simple compound had an abundance of uses in the body, ranging from the nervous system to the reproductive system. Its many uses are still being explored, and it is hoped that it can play an active role

    Vasodilation will occur quickly and result in the extremities feeling hot and painful (Carrasco 2008). Non pharmaceutical treatments for Raynaud’s disease include acupuncture, massage therapy, and nitric oxide, which test the duration (Appiah 1997, Tucker 1999, Walton 2007). Massage therapy and nitric oxide prove to decrease the duration, but acupuncture does not (Appiah 1997, Tucker 1999, Walton 2007). Massage therapy is used to treat Raynaud’s disease by treating the fascia tissue of the affected

    administer, with low incidence of side effects. Nitric oxide, a free radical gas with a short half life, is a potent inflammatory mediator and intercellular signaling molecule, was first used for endothelium-derived relaxing factor and a primary regulator of blood pressure. Recently many studies showed that it involved in various aspect of female reproductive physiology including the process of cervical ripening [5, 6]. In animal models, nitric oxide level increases in the cervix in the later stages

    Aldosterone plays an important role in regulating the body’s salt and water balance by controlling the activity of epithelial sodium channels in the renal collecting duct and may cause swelling and stiffening of the vessel while also altering its nitric oxide output, which affects the vessel’s ability to vasodilate (Nagata, 2006). Salt consumption leads to a transient increase in plasma volume and a subsequent rise in arterial blood pressure as extracellular volume shifts back to normal (Hamlyn et al

    central nervous system sends orders to the heart, so that it pumps faster, sending blood to oxygenate the increase of blood flow in muscles involved in sexual activity. Nitric oxide, serotonin, dopamine, epinephrine, and norepinephrine, are just a few of the neurotransmitters and neuro-peptides involved in sexual activity. Nitric oxide (NO) plays a critical role in both male and female sexuality. In penile erections, NO stimulates the release of guanylate cyclase, which, in turn, converts GTP to cGMP
