COPD: balancing oxidants and antioxidants
Chronic obstructive pulmonary disease (COPD) is one of the most common chronic illnesses in the world. The disease encompasses emphysema, chronic bronchitis, and small airway obstruction and can be caused by environmental exposures, primarily cigarette smoking. Since only a small subset of smokers develop COPD, it is believed that host factors interact with the environment to increase the prope...

متن کاملOxidants, antioxidants, alcohol and stroke.
Free radicals are involved in the formation of both atherosclerosis and thrombosis. Therefore, considerable interest has recently been aroused by their role in the development of ischemic cerebral injury. Experimental observations suggest that antioxidants could reduce cerebral arterial vasospasm, reduce infarct size and prevent the development of both atherosclerosis and thrombosis. However, c...
متن کاملFree radicals, oxidants, and antioxidants.
Free radicals are species with one or more unpaired electrons. The unpaired electron results in a species that is often highly reactive. Free radicals have a wide range of reactions; two broad classes of reactions are electron transfer and addition reactions resulting in covalent bond formation. Free radicals can be classified as reducing (donating an electron to an acceptor) or oxidizing (acce...
متن کاملOxidants and Antioxidants in Medical Science
Advanced glycation end products (AGEs) are known to increase in osteoporosis. Methylglyoxal is AGEs precursor that is toxic to osteoblasts. Methylglyoxal toxicity in osteoblasts involves oxidative stress. The involvement of reactive oxygen species (ROS) in changes of MC3T3E1 preosteoblast cell line morphology caused by methylglyoxal exposure is still unknown. This study was aimed to investigate...
