Effect of harvest time on physicochemical quality parameters, oxidation stability, and volatile compounds of extra virgin olive oil

The aim of this study was to determine the changes in some physicochemical properties of olives (fruit weight, water content and oil content) and olive oils (total chlorophyll, carotenoid, pheophytin a, peroxide value and free acidity), and in the chemical properties (fatty acids, tocopherols, phenolics, oxidation stability and volatile profiles) of oils during ripening.Ripening indices (RI) of olive samples were 1.93 (unripe), 4.28 (ripe) and 5.89 (overripe). Most of the mentioned features changed with ripening. During ripening there was a sharp decrease in total chlorophyll, carotenoid and pheophytin a contents. An increase in oleic and linoleic acids and a decrease in palmitic acid were found in the fatty acid composition. Olive oils showed strong relations among oxidation stability, tocopherol content, total phenols content, and antiradical actvity of phenol extracts and these parameters decreased with maturation. Nevertheless, higher amounts of trans-2-hexenal were found in the oil from ripe olives than from unripe and overripe olives. On the other hand, the highest concentration of hexanal was found in the oil from overripe olives.In general, significant differences were observed in fruit weight, pigments, free acidity, fatty acid, tocopherol, and total phenolics contents, radical scavenger activity, oxidation stability, phenolic profile and volatile profile between the olive oils from the Gemlik cultivar at different stages of maturation

Ультраструктурные изменения слизистой оболочки верхнечелюстной пазухи у больных одонтогенным синуситом

Features of ultrastructure of a mucous membrane of maxillary sinus are investigated at odontogenic sinusitis depending on the reason and prescription of disease. It is established, that the deepest destructive changes are found out in patients with oroantral message and stay in a sinus root material on a basis of zinc-oxidevgenol paste.Изучены особенности ультраструктуры слизистой оболочки верхнечелюстной пазухи при одонтогенном синусите в зависимости от причины и давности заболевания. Наиболее глубокие деструктивные изменения обнаружены у больных с ороантральным сообщением и наличием в пазухе пломбировочного материала на основе цинк-оксидэвгенольной пасты

Determination of the epidural catheter withdrawal time in patients mistakenly given clopidogrel and aspirin in the early postoperative period [Postoperatif Erken Dönemde Epidural Kateter Takiliyken Yanlişlikla Klopidogrel Ve Aspirin Verilen Hastada Kateter Çekilme Zamaninin Belirlenmesi]

Many complications may develop due to applications of neuroaxial block. Since epidural hematoma may develop during catheter placement as it may also develop following catheter withdrawal, both epidural catheter placement and withdrawal in patients on anticoagulant therapy require attention. In this case report, we present a patient who underwent aortic right iliac artery bypass grafting with combined spinal epidural anesthesia and given 75 mg clopidogrel and 100 mg salicylate by the surgical team before catheter removal in the early postoperative period

Ultrastructural changes of mucous membrane maxillary sinus at patients by odontogenic sinusitis

Features of ultrastructure of a mucous membrane of maxillary sinus are investigated at odontogenic sinusitis depending on the reason and prescription of disease. It is established, that the deepest destructive changes are found out in patients with oroantral message and stay in a sinus root material on a basis of zinc-oxidevgenol paste

A new rank sensitivity metric for decision support

Assessing the change in the relative performance of competing systems across a factor space generated by a combination of input variables is a common problem in decision making. We propose a new metric to assess the sensitivity of the performance rankings of a set of options when input variables are changed. The proposed metric is useful in foreseeing the impact of changing values of input variables on an output metric in complex systems through computer simulation experiments. Numerical characteristics of the proposed metric are illustrated and discussed and an application is provided to illustrate use of our metric in decision support
