The Evaluation of Inhibitory Effects of Selected Plant Extracts on Antioxidant Enzymes
(Parlar Scientific Publications, 2015) Moghaddam,N.S.; Isgor,B.S.; Isgor,Y.G.; Geven,F.; Yildirim,O.; 01. Atılım University
Plants and most of the plant derived compounds have been known because of their potential pharmaceutical effects for a long time. They are playing an important role on the treatment of several diseases from diabetes to various types of cancers. Today most of the clinically effective pharmaceuticals are developed from plant derived ancestors in the history of medicine. In this study different parts of the plants, namely Centaurea virgata (Lam.), Cichorium intybus (L.), Euporbia macroclada (Boiss.), Melilotus officinalis (L.) Pall, and Zygophyllum fabago (L.) were evaluated for their potential medicinal value in terms of biological targets which are participating in antioxidant defense such as catalase (CAT), glutathione-S-transferase (GST), superoxide dismutase (SOD) and glutathione peroxidase (GPx). The results indicate that the highest total phenolic contents of leaf and flower extracts were for E. macroclada. The highest flavonoid contents are detected for the leaves of E. macroclada and Z. fabago. The evaluation of extracts against biological targets reveals that the fruit extract of Z. fabago and the flowers of C. intybus show the inhibition against GST. For CAT, the highest inhibition is observed with E. macroclada leaf extract. Among the extracts analyzed, the only but slight SOD inhibition is determined with flower part of E. macroclada. © by PSP Volume 24 - No 1. 2015.

Prioritizing Use Cases for Development of Mobile Apps Using Ahp: a Case Study in To-Do List Apps
(Springer, 2019) Yildirim,O.; Peker,S.; Software Engineering; 06. School Of Engineering; 01. Atılım University
With the rapid development of communication technologies, the uses of mobile apps have increased in a significant manner over the past few years. Every day many different types of mobile apps are uploaded to mobile application markets. However, it is very difficult for the apps to stay competitive and survive in these marketplaces. Covering the requirements fitting the needs of users is one of significant factors in mobile apps’ success in the market. In this regard, this study aims to use Analytic Hierarchy Process (AHP) to evaluate the use cases for the development of mobile apps. The results show that AHP provides an efficient tool which can be used to determine importance of the requirements in mobile apps considering users’ preferences. © 2019, Springer Nature Switzerland AG.
