There is increasing evidence that menopause due to oxidative imbalance will lead to metabolic disorders (1). Menopause also increases food intake and body weight gain and is associated with abnormalities in lipid metabolism (2). More recent experimental studies confirm that ovariectomy cause oxidative stress and cell damage in animals (1,3,4). Steroid hormones, particularly estrogen, are natura...

Oxidative stress and overwhelming free radicals associated with diabetes mellitus are likely to be linked with development of certain complication such as retinopathy, nephropathy and neuropathy. Treatment of diabetic subjects with antioxidant may be of advantage in attenuating these complications. Olive leaf (Oleaeuropaea), has been endowed with many beneficial and health promoting properties ...

Glucocorticoid-induced osteoporosis is one of the common causes of secondary osteoporosis. Piper sarmentosum (Ps) extract possesses antioxidant and anti-inflammatory activities. In this study, we determined the correlation between the effects of Ps leaf water extract with the regulation of 11β-hydroxysteroid dehydrogenase (HSD) type 1 enzyme activity in serum and bone of glucocorticoid-induced ...

antioxidant effect of olive leaf extract (ole) was studied on motility, viability, plasma membrane integrity of spermatozoa and malondialdehyde production in 12 ross 308 roosters at their 30 weeks of age. semen samples were collected by abdominal massage in 5 times. in each session after the initial sperm assessment, collected samples were pooled and diluted with sexton extender.samples were sp...

Data from Spanish and Italian olive orchards with different cultivars (‘‘Manzanilla’’, ‘‘Frantoio’’, ‘‘Leccino’’, ‘‘Razzola’’ and ‘‘Taggiasca’’) growing in different environments (southern Spain; north, centre and south of Italy) were used to illustrate how models on water use and photosynthetic behaviour of the olive tree can be useful tools for choosing pruning intensity and canopy shape for ...

Differences in pest management of olive orchards may affect the development of olive trees and may be reflected in terms of absolute and relative asymmetry, mass, and quality of the leaves. Leaf mass and residual leaf mass of olive trees were significantly greater under organic management than other pest management regimes. The analysis revealed that leaves from trees under different pest manag...

A commercial plant extract derived from olive tree leaf (Olea europaea) (LExt) and its major compound, oleuropein (Ole), inhibited the in vitro infectivity of the viral haemorrhagic septicaemia virus (VHSV), a salmonid rhabdovirus. Incubation of virus with LExt or Ole before infection reduced the viral infectivity to 10 and 30%, respectively. Furthermore, LExt drastically decreased VHSV titers ...
