Cisplatin is a major anti-neoplastic agent which nephrotoxicity is its main side effect and limits its usage in cancer chemotherapy. Reactive oxygen species (ROS) are highly responsible for cisplatin induced nephropathy, so we determined the effects of oral administration of ethanolic olive leaf extract (OLE) as a plant antioxidant on nephrotoxicity of this drug. Material and methods: 21 adult...
pollen grains as well as whole plants of four olive (olea europaea l.) cultivars were screened for nacl salinity stress. different vegetative and physiological indexes of the cultivars were analyzed. leaf and root na/k ratio as well as stomatal resistance of plants exposed to salinity proved to be appropriate indexes of whole plant response to salt stress. whereas, in vitro pollen germination p...
This study examined how sap flow in shoots and branches of a mature olive tree (Olea europaea ‘Coratina’) related to morphological traits which are linked to tree hydraulic architecture. Spatial and temporal variations of sap flow within the tree canopy were investigated; they were analyzed with respect to the ratio between sapwood area and leaf area (SA/LA), and in relation to evaporation dema...
background and objectives: oleaceae family contains approximately 20 species of small trees and ancient world of the mediterranean, north africa, southeast asia, north to southern china, scotland and east australia have a wide dispersion. they are evergreen and have small leaves that are integrated have been met and the fruit is drup. olive trees resistant to drought and adapt to poor soils and...
1. Large-scale invasions of riparian trees can alter the quantity and quality of allochthonous inputs of leaf litter to streams and thus have the potential to alter stream organic matter dynamics. Non-native saltcedar (Tamarix sp.) and Russian olive (Elaeagnus angustifolia) are now among the most common trees in riparian zones in western North America, yet their impacts on energy flow in stream...
Method We conducted a randomized, double-blinded, placebo controlled, crossover trial on an overweight middle aged male population at risk of developing the metabolic syndrome comparing olive leaf extract containing 51 mg oleuropein and 9.7 mg hydroxytyrosol to placebo. We measured insulin sensitivity (Matsuda method), pancreatic b-cell responsiveness (oral disposition index), lipid profile, am...
Olea europaea L. leaves are an agricultural waste product with a high concentration of phenolic compounds; especially oleuropein. Oleuropein has been shown to exhibit anti-proliferative activity against a number of cancer types. However, they have not been tested against pancreatic cancer, the fifth leading cause of cancer related death in Western countries. Therefore, water, 50% ethanol and 50...
Protective effects of grape (Vitis vinifera) seed (GSE), Citrus spp. fruits (CE) and olive {Olea europaea L.) leaf (OL) extracts, the flavonoids diosmin and rutin, widely used as pharmaceuticals, and dimethylsulphoxide (DMSO) against chromosomal damage induced by X-rays were determined by using the micronucleus test for anticlastogenic activity. The reduction of the frequency of micronucleated ...
Olive tree (Olea europaea L.) leaf is known to have a number of bioactive properties being antioxidant, antihypertensive, antiatherogenic, anti-inflammatory, antifungal, antiviral and antimicrobial. In this study, the immunomodulatory roles against oxidative damage caused by carbon tetrachloride (CCl4) in Saccharomyces cerevisiae were investigated. four groups formed; namely, (i) Control Group:...
Endophytes have an intimate and often symbiotic interaction with their hosts. Less is known about the composition and function of endophytes in trees. In order to evaluate our hypothesis that plant genotype and origin have a strong impact on both, endophytes of leaves from 10 Olea europaea L. cultivars from the Mediterranean basin growing at a single agricultural site in Spain and from nine wil...
