Evaluation of in-office tooth whitening treatment with violet LED: protocol for a randomised controlled clinical trial
Published 2018-09-01“…Introduction In-office tooth whitening treatment using violet light emited diode (LED) (405 nm) is a novel bleaching method that causes less sensitivity while offering the same effectiveness as the gold standard (35% hydrogen peroxide, H2O2). This study describes a protocol for the first randomised controlled clinical trial to compare the effects of the two methods.Methods and analysis Eighty patients will be divided into four groups: G1 violet LED; G2 violet LED +35% carbamide peroxide; G3 35% H2O2 and G4 violet LED +gingivoplasty. …”

The Role of Tetrahydrobiopterin and Dihydrobiopterin in Ischemia/Reperfusion Injury When Given at Reperfusion
Published 2010-01-01“…Tetrahydrobiopterin (BH4) is an essential cofactor of endothelial NO synthase (eNOS) to produce NO, whereas dihydrobiopterin (BH2) can shift the eNOS product profile from NO to superoxide, which is further converted to hydrogen peroxide (H2O2) and cause I/R injury. The effects of BH4 and BH2 on oxidative stress and postreperfused cardiac functions were examined in ex vivo myocardial and in vivo femoral I (20 min)/R (45 min) models. …”

State of spatial memory and antioxidant system activity of rats in the dynamics of development of blast-induced traumatic brain injury
Published 2022-09-01“…The analysis of catalase activity revealed a significant decrease of this enzyme activity in blood plasma of the rats in the experimental group in comparison with rats of sham and intact groups: on day 1 – by 35% (p<0.01), on day 3 – by 27% (p<0.01) and by 12% on day 7 of the post-traumatic period (p<0.05), which indicates the involvement of catalase in the reaction of hydrogen peroxide inactivation. Correlation analysis between spatial memory and catalase activity in experimental rats showed a negative relationship of medium degree on day 1 (r=-0.3, p<0.01) and a negative relationship (r=-0.2, p<0.01) of weak degree on day 3 of post-traumatic period, indicating increased formation of free radicals during this period. …”
