Antioxidants: how good are they?
O xidation processes are essential in normal cell metabolism. Free radicals, i.e. reactive oxygen and nitrogen compounds, are formed continuously.

متن کاملare antioxidants helpful for disease prevention?
free radicals are produced continuously in the cells as part of normal cellular function, however excess production might play a role in pathophysiology of many disease conditions, including cancer, alzheimer's disease, atherosclerosis and some of the drug-induced toxicity. many basic research studies and observational epidemiologic studies in human suggest that antioxidants can prevent oxidati...
متن کاملPulmonary vasodilators.
Pulmonary vasodilators are an important treatment for pulmonary arterial hypertension. They reduce pulmonary artery pressure; improve hemodynamic function; alter ventilation/perfusion matching in the lungs; and improve functional quality of life, exercise tolerance, and survival in patients with severe pulmonary arterial hypertension. This paper reviews the currently available pulmonary vasodil...
