nineteen bread wheat genotypes were selected to examine the effect of glycine betaine (gb, 100 mm) on various photosynthetic gas exchange parameters under drought stress and to study the relationship of these parameters with non-enzymatic antioxidants. drought stress caused a significant decline in net co2 assimilation rate (pn), stomatal conductance (gs), intercellular co2 concentration (ci) a...

The involvement of ethylene in reversal salt (NaCl; 50 mM) stress on photosynthetic activity and growth by salicylic acid (SA; 0.5 together with sulfur (S; 2.0 was studied mustard (Brassica juncea L. cv. Pusa Vijay). Application SA plus SO42? improved through markedly increased S-assimilation, strengthening antioxidant defense system limiting NaCl-accrued oxidative consequences more conspicuous...

Although it is well known that physical training ameliorates brain oxidative function after injuries by enhancing the levels of neurotrophic factors and oxidative status, there is little evidence addressing the influence of exercise training itself on brain oxidative damage and data is conflicting. This study investigated the effect of well-established swimming training protocol on lipid peroxi...

Chronic hepatitis C virus (HCV) infection leads to increased oxidative stress in the liver. Hepatic antioxidant enzymes provide an important line of defense against oxidative injury. To understand the antioxidant responses of hepatocytes to different HCV proteins, we compared changes in antioxidative enzymes in HCV-core and HCV-nonstructural protein expressing hepatocyte cell lines. We found th...

Trehalose 6-phosphate (T6P) regulates sugar levels and starch metabolism in a plant cell thus interacts with various signaling pathways, after converting T6P into trehalose (Tre), it acts as vital osmoprotectant under stress conditions. This study was conducted using wheat (Triticum aestivum L. cv. Norin 61) mustard (Brassica juncea BARI sharisha 13) seedlings to investigate the role of Tre imp...

As it was previously reported, black spot development in the skin of Hass avocado has been related to a decreased antioxidant defense system. The aim this study investigate effect different postharvest storage conditions on controlling targeting their system (non-enzymatic and enzymatic) skin. Four treatments (T1: regular air (RA) at 5 °C for 40 d; T2: controlled atmosphere (CA) 4 kPa O2 6 CO2 ...

BACKGROUND & OBJECTIVE Overproduction of lipid peroxidation byproducts and disturbances in antioxidant defense system have been implicated in the pathogenesis of several diseases including oral cancer. Though several studies have been done on the level of lipid peroxidation and antioxidants in oral cancer patients, there are no reports in patients with various clinical stages of oral squamous c...

Antioxidants in plant cells mainly include glutathione, ascorbate, tocopherol, proline, betaine and others, which are also information-rich redox buffers and important redox signaling components that interact with cellular compartments. As an unfortunate consequence of aerobic life for higher plants, reactive oxygen species (ROS) are formed by partial reduction of molecular oxygen. The above en...
