To investigate the effect of post-ischemic adaptation on myocardial perfusion injury in patients with ST segment elevation infarction by percutaneous coronary intervention. 80 were selected and divided into observation group (receiving treatment, 46 cases) control (without a total 34 then two groups compared serum free oxygen radicals (lipid peroxide, nitric oxide, hydroxyl), detection stress (...

Three new 8-alkylcoumarins, 7-O-methylphellodenol-B (1), 7-methoxy-8-(3-methyl- 2,3-epoxy-1-oxobutyl)chromen-2-one (2), and 3'-O-methylvaginol (3), together with seven known compounds (4-10) were isolated from the fruits of Cnidium monnieri. Their structures were determined by detailed analysis of spectroscopic data and comparison with the data of known analogues. All the isolates were evaluate...

A range of some Iranian monofloral honeys were assayed for antibacterial activity with and without hydrogen peroxide which is inactivated by the addition of catalase. I t was found that the high amount of antibacterial activity in honeys was due to a factor other than hydrogen peroxide. The test microorganism Staphylococcus aureus, was not inhibited by the acidity or the osmolarity of the h...

drought is one of the important environmental stresses that reduce the crop growth. oxidative stress is a secondary stress due to drought and other abiotic stresses. in order to study the effect of exogenous application of hydrogen peroxide on drought tolerance of glob amaranth (gomphrena globosa l.), an experiment was conducted in greenhouse conditions. this study was designed as factorial bas...

salinity is one of the environmental stresses that have limited influence on the crop growth. oxidative process is a secondary stress due to salinity. oregano is enumerated as one of the most important of medicinal plant that its production and development is possible in iran. in order to study the effect of exogenous application of hydrogen peroxide on salt tolerance in oregano (origanum major...

Catalytic wet air oxidation (CWAO) of phenol over activated carbon catalysts in presence of a typical promoter such as hydrogen peroxide has been studied. The experiments were carried out in a trickle-bed reactor at given operating conditions (Cinlet phenol= 1 g/L, Cinlet H2O2= 5g/L, T=127 oC, PT=8 atm and WCAT=2.5 g) in a wide range of space time values (W/QL=20-320 gCAT·h/L). The effect of th...

To explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. The electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. The graphene with the most stable configuration defect named as SW defect is considered. The hig...

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...

Chronic rhinosinusitis is a chronic inflammatory condition that caused by many factors. However, the underlying mechanism of remains unclear. The current study focused on roles triptolide hydrogen peroxide treated nasal epithelial cells and underling mechanism. Hydrogen human were cultured different concentrations triptolide, cell growth death determined counting kit-8 flow cytometry methods. M...

Serum ceruloplasmin (CP), a marker relevant to copper metabolism, is one of famous inflammation markers with a reduction in Wilson's disease, whereas serum ferritin is a marker relevant to iron metabolism. Recently, ferritin is pointed out to be related with oxidative stress. However, there is still no population research which showed the relation of CP and ferritin. Therefore, we investigated ...
