abstractbackground : in order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 mhz low level ultrasound based on °oh radicals generated by acoustic inertial cavitation in aqueous solution was monitor...

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...

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...

A vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as DNA, proteins and lipids. When free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. Therefore, the body should be protected by an enzymatic or no...

qct calculations were performed to study the behavior of energized nh2oh formed by association collision of nh2 radical with oh radical. a potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. h2o, hon, hno, nh3, o, h2no, cis or trans-honh, and h products and two vibrationally energized nh2oh and nh3o adducts were obs...
