The changes in the activity of antioxidant enzymes, like superoxide dismutase, ascorbate peroxidase, catalase and glutathione reductase, and growth parameters such as length, fresh and dry weight, proline and H2O2 contents, chlorophyll fluorescence (Fv/Fm), quantum yield of PSII and the rate of lipid peroxidation in terms of malondialdehyde in leaf and root tissues of a chickpea cultivar (Cicer arietinum L. cv. Gokc,e)under salt treatment were investigated. Plants were subjected to 0.1, 0.2 and 0.5 M NaCl treatments for 2 and 4 days. Compared to controls, salinity resulted in the reduction of length and of the fresh and dry weights of shoot and root tissues. Salinity caused significant ( P < 0.05) changes in proline and MDA levels in leaf tissue. In general, a dose-dependent decrease was observed in H2O2 content, Fv/Fm and quantum yield of photosynthesis under salt stress. Leaf tissue extracts exhibited three activity bands, of which the higher band was identified as MnSOD and the others as FeSOD and Cu/ZnSOD. A significant enhancement was detected in the activities of Cu/ZnSOD and MnSOD isozymes in both tissues. APX and GR activities exhibited significant increases ( P < 0.05) in leaf tissue under all stress treatments, whereas no significant change was observed in root tissue. The activity of CAT was significantly increased under 0.5 M NaCl stress in root tissue, while its activity was decreased in leaf tissue under 0.5 MNaCl stress for 4 days. These results suggest that CAT and SOD activities play an essential protective role against salt stress in chickpea seedlings.

Effect of pectin methyl esterase (PME) and CaCl2 infusion on the cell integrity of fresh-cut and frozen-thawed mangoes: An NMR relaxometry study
Kırtıl, Emrah; Öztop, Halil Mecit; Barrett, Diane M.; McCarthy, Michael J. (Elsevier BV, 2014-12)
This study describes the use of Nuclear Magnetic Resonance (NMR) relaxometry to understand the effect of pectin methyl esterase (PME) + CaCl2 infusion under different conditions on cell integrity of fresh-cut and frozen-thawed mangoes. Infusion experiments were performed at: atmospheric pressure, vacuum conditions of 50 kPa and 10 kPa. For NMR relaxometry experiments T-2 (spin-spin relaxation time), T-1 (spin-lattice-relaxation times) and 2D T-1-T-2 experiments were performed. Results showed that, as the se...
Effect of thermal treatment on secondary structure and conformational change of mushroom polyphenol oxidase (PPO) as food quality related enzyme: A FTIR study
Baltacioglu, Hande; Bayındırlı, Alev; Severcan, Mete; Severcan, Feride (2015-11-15)
In order to understand the conformational changes of polyphenol oxidase (PPO), which is a food quality related enzyme, after thermal treatment, secondary structure changes of the enzyme were analyzed by using Fourier Transform Infrared (FTIR) spectroscopy and compared with the change in enzyme activity in the temperature range of 25-80 degrees C. Fourier self-deconvolution, neural network (NN) and curve-fitting analysis were applied to the amide I band of FTIR spectra for detail analysis of secondary struct...
EFFECT OF TANNIC ACID ON GLUTATHIONE S-TRANSFERASE AND NAD(P)H: QUINONE OXIDOREDUCTASE 1 ENZYMES IN RABBIT LIVER AND KIDNEY
KARAKURT, SERDAR; Adalı, Orhan (2011-01-01)
Glutathione S-transferase and NAD(P)H: quinone oxidoreductase 1 enzymes have important roles in detoxification and also activation of a wide variety of chemicals. Moreover, resistance of tumor cells against chemotherapeutic agents has been implicated in GST activities. The aim of this study was to investigate the effect of polyphenolic compound tannic acid on rabbit liver and kidney glutathione S-transferase and NAD(P)H: quinone oxidoreductase 1 enzyme activities. Tannic acid was found to be a potent inhibi...
Effects of the non-steroidal anti-inflammatory drug celecoxib on cholesterol containing distearoyl phosphatidylcholine membranes
Sade, Asli; Banerjee, Sreeparna; Severcan, Feride (2011-01-01)
The effects of different concentrations of celecoxib on the acyl chain order, dynamics and the hydration status of the head group and interfacial region of model membranes containing DSPC and cholesterol were investigated in detail using Fourier transform infrared spectroscopy. Our results reveal that regardless of the presence of cholesterol, celecoxib is able to alter the physical properties of membranes. It exerts opposing effects on membrane order at high and low concentrations and decreases membrane fl...
Effect of nutrients on culture dynamics of marine phytoplankton
Eker-Develi, E; Kıdeyş, Ahmet Erkan; TUĞRUL, SÜLEYMAN (2006-01-01)
The effects of nitrate, ammonium and phosphate on the abundance, chlorophyll a content (chl a), in vivo fluorescence, particulate organic carbon, nitrogen, phosphorus and cell morphology of the diatom Skeletonema costatum, the dinoflagellate Prorocentrum micans and the coccolithophore Emiliania huxleyi were investigated in the laboratory. The carbon:chlorophyll a ratio (as weight), a parameter often used in productivity estimates, differed substantially among the three species as well as at different nutrie...
