Background and Objective: The tissue oxidative stress is the most important factor in the development of diabetic kidney disease. The purpose of this study was to evaluate the therapeutic effect of swimming training and Arbutin supplement on diabetes-induced renal oxidative stress. Materials and Methods: 42 male Wistar rats were randomly divided into 6 groups (7 rats per group) of control, d...

Melissa officinalisL. is a herbaceous and perennial plantof family Lamiaceae. It is an antioxidant plant that is found in northern Iran. Aluminum is a heavy metal that generates oxidative stresses in plants, among which antioxidant enzymes are among the most important herbal defensive measures in inhibition of reactive oxygen species.Iron is an essential, while low-consuming, element for plants...

Antioxidative activity of two in vitro cultivated Hypericum species - H. rumeliacum Boiss. and H. tetrapterum Fr. - was estimated after cryopreservation. Both species were successfully regenerated after a cryopreservation procedure performed by the vitrification method. H. tetrapterum did not manifest any significant oxidative stress-induced changes caused by low-temperature treatment. Converse...

Lippia citriodora H.B.K. is a valuable medicinal plant of Verbenaceae family. This study was calculated to evaluate potential role of salicylic acid (SA) in diminish the harmful effects of drought stress on L. citriodora plants. SA (0.5 and 1 mM) was used to L. citriodora plants grown under stressed (5, 10, 15 and 20% PEG) and unstressed conditions. Fresh weight (FW) and relative water content ...

The effects of postharvest oxalic acid (OA) treatment on ethylene production, fruit quality, bioactive compounds and antioxidant activity of peach fruit, were examined. Fruits were treated with oxalic acid immediately after harvest and stored at 1° C and 90% relative humidity for 28 days. The oxalic acid treated peach fruit exhibited significantly lower levels of ethylene production, pH, total ...

This study aimed to elucidate the influence of environment pH on survival, growth, energy allocation and oxidative damage of juvenile Scophthalmus maximus (19.89±0.25 g). Six pH treatments (6.3±0.2, 6.8±0.2, 7.3±0.2, 7.8±0.2, 8.3±0.2, 8.8±0.2) lasting for eight weeks were included. Measurements of survival (SR), feed conversion ratio (FCR), speci...
