Measuring In Vivo Free Radical Production by the Outer Retina.
PURPOSE Excessive and continuously produced free radicals in the outer retina are implicated in retinal aging and the pathogenesis of sight-threatening retinopathies, yet measuring outer retinal oxidative stress in vivo remains a challenge. Here, we test the hypothesis that continuously produced paramagnetic free radicals from the outer retina can be measured in vivo using high-resolution (22-μ...
متن کاملproduction of hydroxyl free radical, the main mechanism for removing steroid hormones by ultrasound
background: one of the new methods for elimination or destruction of estrogen hormones is ultrasound irradiation. the aim of this study was to determine the main mechanism of steroid hormones removal by ultrasound. methods: in this study, estrogen (e1) and 17 beta-estradiol (e2) were irradiated with ultrasound at different frequencies, powers, and exposure times in two cases: with and without b...
متن کاملRole of leucocytes in free radical production during myocardial revascularisation.
OBJECTIVE To evaluate the role of leucocytes in free radical production in patients with depressed or normal ejection fraction undergoing coronary bypass. DESIGN Two randomised control trials. SETTING Tertiary care centre. PATIENTS AND INTERVENTIONS In the first study, 22 patients with ejection fractions of < or = 40% received blood cardioplegic reperfusion with (n = 11) or without (n = 1...
متن کاملOxidative stress: free radical production in neural degeneration.
It is not yet established whether oxidative stress is a major cause of cell death or simply a consequence of an unknown pathogenetic factor. Concerning chronic diseases, as Parkinson's and Alzheimer's disease are assumed to be, it is possible that a gradual impairment of cellular defense mechanisms leads to cell damage because of toxic substances being increasingly formed during normal cellular...
متن کاملRadiation damage and free radical production in irradiated ribonuclease.
It is probable that transient free radical states are implicated in the chain of events leading to the production of radiation damage. In solids and in dry biological materials, these free radicals are comparatively stable and have been studied by a number of workers in materials of biological interest, including biochemicals (1, 2), bacterial spores (3), and seeds (4, 5). The objective of such...
