BACKGROUND Olive (Olea europea), from the Oleaceae family, is known as a phytoestrogen plant compound, containing Lignans and phenoliccompounds. Some studies have shown phytoestrogens to have spermatogenesis-decreasing effects. OBJECTIVE The present study investigated the effects of a hydro-alcoholic extract of olive fruit on reproductive argons in male rats. MATERIALS AND METHODS The hydro...

Olive lace bugs (Hemiptera: Tingidae) are small sap-sucking insects that feed on wild and cultivated Olea europaea. The diversity of olive bug species in South Africa, the most important producer continent, has been incompletely surveyed. Adult specimens were collected Western Cape province for morphological DNA-based identification, sequencing complete mitogenomes. Cysteochila lineata, Pleroch...

The kinetics of the cometabolism of trichloroethylene (TCE) by the ammonia-oxidizing soil bacterium Nitrosomonas europaea in short-term (<10-min) incubations were investigated. Three individual effects of TCE cometabolism on this bacterium were characterized. First, we observed that TCE is a potent competitive inhibitor of ammonia oxidation by N. europaea. The K(infi) value for TCE (30 (mu)M) i...

The health-promoting effects of various constituents of the olive tree (Olea europaea) are mainly associated with hypoglycaemic and insulin-sensitising activities and have been widely demonstrated in the metabolic syndrome and type 2 diabetes. However, their biological activity in autoimmune type 1 diabetes (T1D) is poorly characterised. Therefore, the influence of O. europaea-derived component...
