A fast and simple method for the oxidative iodination of some aromatic amines, under microwave irradiation, is reported, using diiodine and the the strongly Hbonded urea-hydrogen peroxide addition compound (H2NCONH2···H2O2, UHP) as the oxidant. The reactions were carried out in boiling CHCl3 under a reflux condenser to afford, within 10 minutes, the purified monoiodinated products in 40-80% yie...

hydrogen peroxide, an oxidizing agent used in surgery for its antiseptic properties, has been associated with life-threatening complications. we report a case of suspected gas embolism following irrigation of a tibial bone cyst with hydrogen peroxide in a five year-old boy under general anesthesia, who died despite resuscitative measures and a long stay in the intensive care unit.

two groups of olive cultivars were characterized as showing low (tokhmkabki) and high (roghani) rooting percentage after application of iba treatment. semi-hard wood cuttings were dipped in h 2 2 o 2 (0-3.5% w/v) and iba (4000 mg.l -1 ) and also they were investigated in combination. h 2 o 2 alone did not stimulate rooting of olive cuttings and there were no significant differences between this...

This paper describes the experiments carried out to analyse total dissolved N involving UV oxidation and high temperature catalytic oxidation (HTCO) methods. Standards of known N concentrations (i.e. ammonium and EDTA) irradiated with UV oxidation for 6 h were found to show good oxidation efficiency (72-107%). However, poor recovery was recorded for urea (2-20%). The addition of reaction initia...

introduction: nowadays, spermatogonial stem cells (sscs) cultivation has been used by many researchers as an effective tool for infertility treatments. oxidative conditions can be effective on cell proliferation and differentiation of these cells. so, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during sscs in vitro culture. ...
