Evaluation of the physiological and biochemical traits can help to identify strategies for selection of resistant cultivars and increased crop yield production under diverse environmental conditions such as SALT stress conditions. To this end, an experiment was conducted in a greenhouse based on a completely randomized design (CRD) with three replications. The experimental factors were six...
The glutathione peroxidase-glutathione reductase system, an alternative pathway for metabolic utilization of H2O2 [Chance, Sies & Boveris (1979) Physiol. Rev. 59, 527-605], was investigated in Trypanosoma cruzi, an organism lacking catalase and deficient in peroxidase [Boveris & Stoppani (1977) Experientia 33, 1306-1308]. The presence of glutathione (4.9 +/- 0.7 nmol of reduced glutathione/10(8...
conclusions the results of our study proposed that there is a loss or inactivation of antioxidant factors, coupled with increased lipid peroxidation during the procedure of hd, possibly through the dialyzer membrane, with probable consequences on the severity of illness. results the sod, gpx and cat were decreased after hd (p < 0.05). also, frap was shown to decrease after hd (p < 0.05). howeve...
In order to investigate the effect of putrescin and salicylic acid on some physiological and antioxidant properties of stevia under salinity stress, a factorial experiment was conducted in a completely randomized design with three replications. In this experiment, samples were exposed to different concentrations of putrescine (0, 0.5 and 1 mM), salicylic acid (0 and 0.5 mM) and salinity (0, 75 ...
A photoresponsive nanozyme with peroxidase- and catalase-like activities, photodynamic photothermal properties is designed in article number 2007090 by Huiyu Liu co-workers. Its synergistic catalytic therapy dual phototherapy show unique advantages for tumor treatment.
The activities of catalase, peroxidase, indoleacetic acid (IAA) oxidase and peroxide levels in cucumber plants during and after chilling were determined. During 96 hours at 5 C and 85% relative humidity, catalase activity declined, IAA oxidase activity increased, and peroxide concentrations increased. Peroxidase activity was not affected by chilling. When chilled plants were returned to 25 C to...
Although the importance of prosthetic groups to the activity of certain enzymes has been much studied, the part played by the protein portion of the molecule has received little attention. Haemoglobin, catalase and peroxidase all have the same prosthetic group, namely, protohaematin, yet the attachment of different proteins gives them distinct and characteristic properties. Thus haemoglobin is ...
Abstract In order to evalution of antioxidant enzymes activity and yield of flower of chamomile genotypes under drought stress condition and foliar application of nano iron chelated, a factorial experiment in a randomized complete block design with three replications was conducted at greenhouse research farm of the University of Zabol in 2014. Experimental treatments included drought stres...
Chickpea is highly sensitive to salt stress. Several compounds are examined to minimize the harmful effects of salt stress. In this research the effect of gibberellic acid (10 and 20 µM) on physiological parameters in two cultivars of Iranian chickpea (Jam and Kaka) under salt stress (80mM NaCl) were studied. The results showed that chlorophylls and protein contents were decreased in plan...
GM2 and GA2 gangliosides from the brain of a patient who died of Sandhoff's disease were purified by solvent partition, silicic acid and silica gel column chromatography, and silica gel preparative thin-layer chromatography. They were tritiated in the terminal N-acetylgalactosamine residue using galactose oxidase and sodium [3H]borohydride with the inclusion of catalase and peroxidase into the ...
