Due to high water content and perishability, the raspberry fruit is sensitive postharvest fungal contamination losses. In this study, chitosan was used as an edible coating increase storage of raspberries, nanotechnology efficiency. The treated with emulsion containing nanoparticles (ECNPC) at 0, 2.5, 5 g L?1, stored for 9 d. Decay extension rate, phytochemical contents, including total phenoli...

Cu2Zn2-superoxide dismutase (CuZn-SOD) was purified from chicken liver. The liver enzyme had a subunit Mr of 16900 and contained equimolar amounts of copper and zinc [0.260 (w/w) for each]. Aortic CuZnSOD had the same Mr as estimated by gel filtration and cross-reacted with antibodies to the liver enzyme. Both enzymes were inhibited by 1.0 mM-NaCN. Within 24-72 h after hatching, total SOD activ...

PURPOSE The authors determined the levels of the secreted, interstitially located extracellular superoxide dismutase (EC-SOD), the cytosolic copper- and zinc-containing SOD (CuZn-SOD), and the mitochondrial manganese-containing SOD (Mn-SOD) in tears, cornea, sclera, aqueous humor, lens, vitreous body, and retina of the human eye. METHODS SOD enzymatic activity was determined by the direct spe...

Substantial evidence supports a key role for reactive oxygen species (ROS) in causing cumulative damage to cellular macromolecules, thereby contributing to senescence. Antioxidants can scavenge ROS while protein turnover removes and replaces oxidized proteins. How these defence systems vary with age and with metabolic demand is not well known. In the present study 2H5-phenylalanine was injected...

lignin is one of the major characteristics of plant secondary cell wall that provides structural rigidity for the cells and tissues and hydrophobicity to tracheary elements. internode tissues of aeluropus littoralis as a halophyte grass were sampled at different developmental stages (from the first to the fifth internodes ) and under different nacl concentrations. the influences of nacl and int...

Background: Our purpose was to investigate propolis and its component caffeic acid phenethyl ester (CAPE) for their antioxidant effects on the brain tissue of rats exposed to ionizing radiation (IR). Materials and Methods: Fifty-four male albino Sprague-Dawley rats, divided into six groups, were designed as normal control group, cranial irradiation of 5 Gray alone, irradiation plus CAPE, irradi...

Superoxide dismutase (SOD) activity in murine erythroleukemia cells (MELC) was determined during differentiation induced by hexamethylene bisacetamide. SOD levels in hexamethylene bisacetamide-treated MELC were about twice as high as those of controls. Dose response and kinetic experiments have shown that SOD activity variations are closely related to the amount of inducer and the duration of t...

abstract effect of cr3+ concentrations (1, 2, 4, 6, and 8 mg l-1) on lipid peroxidation / mda production and antioxidative enzyme activity (apox, sod, and ppox) in root and leaf tissues of sweet basil seedlings (ocimum basilicum l.) during 6week treatment in hydroponic culture was studied. increasing cr3+ in the culture medium (≥4 mg l-1) caused significant enhancement of apox, sod, and ppox ac...
