The reseach is subsidised by the Regional Government of Castilla and León in collaboration with the Environmental Services. In the latest project approved ł›y the CICYT, we study the present situation of the main parasitic infections affecting red deer in tke north- west ceNre and south-west of Spain. Our aim is to determine the vansrnission periods of the species involved and the seasonal Linetics of the infections in order țO ăȘS0S5 łhč anİlYläl5’ Stütč 0f health and esablish the nec- essary control measures Tothis end, SS red deer were shotby agens from the Environment Boaid of the Riaão Regional Hurling Reserve and were taken to the Faculty of Yetennary Sciences at León fcr analysis. Each animal was marked and data were taken on their age, sex, weight and physical condition. Afier an external examination for ectoparasites had been canied out they were skinned and necropsìed and their hides, entrails heads and samples of blood and faeces were collected. The animals were divided into adult dœr (43) and young animals (12), of whi‹żi 40 were female and 15 male.

Two of 19 roe deer (Capreolus capreolus) in northern Spain were infested with Cephenemyia stimulator and one individual with Oestrus ovis. Three larvae of O. ovis were recovered from the nasopharynx of an adult female deer examined in February 2017, during the hunting season in the province of Burgos. The larvae were identified by morphology, and DNA sequencing from cytochrome oxidase subunit I and 28S rDNA confirmed the identification of both species of larvae. The possibility of O. ovis parasitizing roe deer should be considered in the diagnosis of nasal bots in cervids. 2024-10-01T00:00:00Z https://hdl.handle.net/10259/10029 Applications of compounds recovered from olive mill waste Flamminii, Federica; González Ortega, Rodrigo; Di Mattia, Carla Daniela; Perito, Maria Angela; Mastrocola, Dino; Pittia, Paola The chapter presents the state-of-the-art on the utilization of phenolic compounds derived from olive mill waste as ingredients in food products. A general introduction regarding the olive oil production chain is presented, focusing on the three main waste streams (olive leaves, olive mill wastewater, and olive pomace), which are well detailed from the chemical composition, bioactive profile, and recovery methods point of view. Encapsulation strategies are discussed in order to provide innovative knowledge regarding the stabilization of polyphenols extract recovered by olive wastes. The latest results of the studies regarding the exploitability of valuable compounds recovered from by-products are deeply discussed, and consumer acceptance of olive oil by-products used as a food ingredient is presented. 2021-01-01T00:00:00Z https://hdl.handle.net/10259/9972 Liposomal Encapsulation of Oleuropein and an Olive Leaf Extract: Molecular Interactions, Antioxidant Effects and Applications in Model Food Systems González Ortega, Rodrigo; Šturm, Luka; Skrt, Mihaela; Di Mattia, Carla Daniela; Pittia, Paola; Poklar Ulrih, Nataša; Poklar The influence of actively/passively encapsulated oleuropein on DPPC liposomes thermal and structural properties, and its antioxidant capacity against lipid peroxidation were investigated. Also, an oleuropein-rich olive leaf extract was encapsulated in soy phosphatidylcholine (PL-90 g) and incorporated in model and commercial drinks. Oleuropein induced a concentration-dependent broadening and splitting of the gel-to-liquid phase transition temperature. Fluorescence measurements revealed a fluidizing effect on liposomes below their gel-to-liquid phase transition temperature, and a higher lipid ordering above, especially to active encapsulation. Oleuropein also showed an antioxidant effect against lipid peroxidation in PL-90 g liposomes. PL-90 g Liposomes with olive leaf extract showed a mean diameter of 405 ± 4 nm and oleuropein encapsulation efficiency of 34% and delayed oleuropein degradation at pH 2.0 and 2.8 model drinks. In conclusion, greater effects were observed on the structure and fluidity of DPPC liposomes when oleuropein was actively encapsulated, while its incorporation into acidic foods in encapsulated form could enhance its stability. 2021-03-01T00:00:00Z
