A new promising mimetic enzyme, a [2Fe-2S] cluster-porphyrin hybrid complex ([2Fe-2S]2TPPS), has been synthesized and applied to the determination of hydrogen peroxide. Under the optimum condition, the calibration graph has a linear range of 8.0 x 10(-8) - 1.0 x 10(6) mol/l H2O2 with a detection limit (3sigma, N = 9) of 5.3 x 10(-9) mol/l.

Wistar rats were given a diet with 8% sodium chloride to induce hypertension and subsequently sacrificed. Glycine max powder was used reduce atenolol’s side effects during the trial. Thirty divided into five groups tested over eight weeks. Rats’ blood pressure (BP) measured tail-cuff NIBP monitor. Biochemical markers like TG, TC, HDL, LDL, VLDL, alanine transferase, aspartate lipid peroxide (LP...

The technique of plasmonic ELISA is utilised here to detect the HIV-1 protein gp120 with the ultralow limit of detection of 8 × 10(-20) M (10(-17) g mL(-1)) in an independent laboratory. It was corroborated that changes in the concentration of hydrogen peroxide as small as 0.05 μM could lead to nanoparticle solutions of completely different tonality.

-Cross-linking of arabinoxylans by ferulate dehydrodimers and incorporation of feruloylated arabinoxylans into lignin were modelled with maize walls (Zea mays cv Black Mexican) containing 5.3-18.0 mg g~ of total ferulates. The proportion of dehydrodimers to total ferulates increased from ca 20 to 45% when dilute hydrogen peroxide was added to walls containing bound peroxidase. About 45% of the ...

the present study was carried out to investigate the effect of various refining processes’ conditions on conjugated dienes in soybean oil. conjugated dienes contents of soybean oil were found to undergo reduction in neutralization and bleaching steps while being increased in deodorization. it was observed that alkali refining (neutralization) through 12 and 14 °bé, bleaching with either acid ac...

The crystallographic structures of two cytochrome c peroxidase (CcP) mutants, CcP(R48L) and CcP(R48K), have been determined. In addition, the electronic absorption spectrum and the hydrogen peroxide reactivity of these two mutants have been determined between pH 4 and 8. Both the crystallographic structure and the electronic absorption spectrum of CcP(R48L) are consistent with exclusive pentaco...

zataria multiflora essential oil, hydrogen peroxide(h2o2) and malachite green (mg) were used to assess their effects on rainbow trout egg hatchability and survival of larvae up to 1-1.2 g body weight using spring water at 12.5 °c, dissovled oxygen 8-9 mg/l, carbon dioxide 7±2 mg/l, ammunia

Huwa-San peroxide (hydrogen peroxide; HSP) is a NSF Standard 60 (maximum 8 mg/L(-1)) new generation peroxide stabilized with ionic silver suitable for continuous disinfection of potable water. Experiments were undertaken to examine the mechanism of HSP against planktonic and biofilm cultures of indicator bacterial strains. Contact/kill time (CT) relationships that achieve effective control were...
