The olive tree, Olea europaea, is native to the Mediterranean basin and parts of Asia Minor. The fruit and compression-extracted oil have a wide range of therapeutic and culinary applications. Olive oil also constitutes a major component of the "Mediterranean diet." The chief active components of olive oil include oleic acid, phenolic constituents, and squalene. The main phenolics include hydro...

Aging is associated with common conditions, including cancer, diabetes, cardiovascular disease, and Alzheimer's disease. The type of multi-targeted pharmacological approach necessary to address a complex multifaceted disease such as aging might take advantage of pleiotropic natural polyphenols affecting a wide variety of biological processes. We have recently postulated that the secoiridoids ol...

Podocyte injuries are associated with progression of diabetic nephropathy (DN). Apelin, an adipocyte-derived peptide, has been reported to be a promoting factor for DN. In this study, we aim to determine whether apelin promotes progression of DN by inducing podocyte dysfunction. kk-Ay mice were used as models for DN. Apelin and its antagonist, F13A were intraperitoneally administered for 4 week...

Baiano A., Terracone C., Viggiani I., Del Nobile M.A. (2014): Changes produced in extra-virgin olive oils from cv. Coratina during a prolonged storage treatment. Czech J. Food Sci., 32: 1–9. Extra-virgin oil is obtained from olive fruits only by mechanical means. The quality of extra-virgin olive oils is affected mainly by hydrolytic and oxidative reactions. For this reason, the commercial shel...

An investigation to optimize the extraction yield and the radical scavenging activity from the agricultural by-product olive tree wood (Olea europaea L., cultivar Picual) using six different extraction protocols was carried out. Four olive wood samples from different geographical origin, and harvesting time have been used for comparison purposes. Among the fifty olive wood extracts obtained in ...

The oxidation of oleuropein and 3-hydroxytyrosol by oxidases laccase, tyrosinase, peroxidase has been studied. use a spectrophotometric method another chronometric made it possible to determine the kinetic parameters Vmax KM for each enzyme. highest binding affinity was shown laccase. antioxidant capacities these two molecules have characterized, finding very similar primary capacity between th...

Olive trees (Olea europaea L.) in natural environments are increasingly being subjected to abiotic stresses, such as water deficit. Arbuscular mycorrhizal (AM) symbioses can improve olive tolerance In the current study, elucidate role of AM fungi regulating deficit resistance olive, effects Rhizophagus irregularis DAOM 197198 on gas exchange, stem potential, phytohormones, carbohydrates and ind...
