Iron overload is known to occur in the West European and American population due to the consumption of iron-rich diets. On the other hand, genetic disorders leading to iron overload are also known. Iron overload leads to increased peroxidation and disruptive disintegration of lipid-rich membranes, and predisposes humans for an enhanced risk of cancer induction. In experimental animals iron ...
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
Objective: Oxidative stress is a leading factor in the development of silver nanoparticle-induced toxicity. This study evaluated the effects of oral prescription of different doses of silver nanoparticles and propolis on lipid peroxidation in male Wistar rats. Materials and Methods: The male wistar rats were randomly divided into four groups. Control group and three different treatment groups ...
Manipulating cell cultures by elicitors is one of the important strategies for induction of valuable metabolites in plant biotechnology. Therefore, in this study the effect of ultrasound and salinity on growth, primary and secondary metabolite production was studied in Dunaliella salina microalgae cell culture. Cell cultures were treated with sodium chloride salt at concentrations of 2 and 3 M ...
considering that the involvement of oxidative stress has been implicated in the toxicity of organophosphate insecticides, the objective of the present study was to investigate antioxidants and oxidative stress markers in the liver and kidney of wistar rats treated with chronic doses of diazinon. in addition, the effect of tert-butylhydroquinone (tbhq), a food-additive antioxidant, on attenuatio...
the present study was designed to investigate the protective effect of ethanol extracts from lindera coreana leaves (lce) on uvb-induced oxidative stress in hacat keratinocytes. the hacat cells were pretreated with lce for 24 h and then exposed to uvb (20 mj/cm2) for 2 h. uvb significantly decreased the cell viability (p<0.05). lce did not exhibit significantly cytotoxic effects and increased t...
cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...
The present investigation is aimed to carry out the in vitro lipid peroxidation and antimicrobial activities of the methanol extract of Mucuna pruriens (MEMP) (Family: Fabaceae) seeds. Lipid peroxidation was monitored by the change in optical density of the prepared concentrations (10-320 g/ml) and the % inhi-bition was calculated. Ascorbate/FeSO4-induced peroxidation was inhibited by standard ...
the study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. goat liver and white new zealand rabbit were used as lipid source for the models. lipid peroxidation study was performed by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide con...
