the present work is carried out to study the antioxidant potential of ethanolic extract of alstonia scholaris linn. ( apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (dpph . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   ethanolic extract of alstonia...

This study evaluates the effects of different additives such as silver ion, medium and energy sources on the efficiency of mixed moderate thermophilic bioleaching approach to extract Cu, Mo and Re from molybdenite concentrate containing 0.98% Cu, 1.56% Fe, 53.84% Mo, and 0.055% Re. Molybdenite was the major phase of Mo-bearing mineral and chalcopyrite, covellite and pyrite were distinguished as...

Abstract-A mathematical modeling was adopted to calculate the ferric ion diffusion coefficient based on the radiation induced magnetic resonance (MR) image intensity change in Fricke-agarose gels. A fast magnetic resonance imaging acquisition technique was employed to avoid the smearing of acquired data due to diffusion over an extended period of time. Our results showed that for a Fricke-agaro...

NADPH-cytochrome c reductase in rat liver microsomes was solubilized by bromelain digestion and purified to homogeneity. An antibody preparation obtained by immunization with this enzyme was found to inhibit the NADPHcytochrome c reductase activity of both the purified enzyme and intact microsomes by more than 90%. This antibody also inhibited the NADPH-dependent peroxidation of microsomal lipi...

The present work is carried out to study the antioxidant potential of ethanolic extract of Alstonia scholaris Linn. ( Apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (DPPH . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   Ethanolic ex...

6-Pentadeca(e)nylsalicylic acids isolated from the cashew Anacardium occidentale L. (Anacardiaceae), commonly known as anacardic acids, inhibited the linoleic acid peroxidation catalyzed by soybean lipoxygenase-1 (EC 1.13.11.12, type 1) competitively without prooxidant effects. Their parent compound, salicylic acid, did not have this inhibitory activity up to 800 pm, indicating that the pentade...

We have described a turn on fluorescent probe BOD-NHOH based on hydroxylamine oxidation for detecting intracellular ferric ions. The probe comprises a signal transducer of BODIPY dye and a Fe(3+)-response modulator of hydroxylamine. It is readily employed for assessing intracellular ferric ion levels, and confocal imaging is achieved successfully.
