Biochemistry of Oxygen and Its Free Radicals
Thrombolytic treatment in acute myocardial infarction achieves coronary patency in most patients.' Mortality in groups treated early after the onset of symptoms is significantly reduced,' but left ventricular function does not always improve.5 Myocardial necrosis during the period of vessel occlusion is partly responsible for the irreversible ventricular impairment that occurs even when the ves...
متن کاملOxygen in Biology and Biochemistry: Role of Free Radicals
A free radical is defined as any atom or molecule that contains unpaired electrons and has independent existence (hence, the term free). A dot is used to represent a free radical species. The abstraction or gain of one electron by a nonradical molecule may (or may not) convert it to a radical species. Free radicals can have positive, negative, or neutral charges [reactions (12.1.1) and (12.1.2)].
متن کاملSemi-radicals of Sub modules in Modules
Abstract: Let be a commutative ring and be a unitary module. We define a semiprime submodule of a module and consider various properties of it. Also we define semi-radical of a submodule of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.
متن کاملQuantification of Radicals Generated in a Sonicator
The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. It can also recombine to form hydrogen peroxide which is very useful in water treatment. In this study, terephthalic acid (TA) and potassium iodide dosimetry were used to quantify and inve...
