An investigation on the antioxidant activities and total phenolics content of Calendula officinalis

An empirical analysis of the relationship between financial deepening and economic growth: the case of Turkey Esen, Kılıç; Voyvoda, Ebru; Department of Economics (2008) This study aims to investigate the direction of the relationship between financial deepening and economic growth after the completion of financial liberalization in Turkey. In order to do this, an unbalanced panel data set of 49 OECD and emerging countries for 1953-2005 period is examined with Granger causality and panel data estimation techniques. In the light of panel data analysis results, quarterly Turkish time series data for 1987-2006 period is examined by using Granger causality, cointegration and Ve...
Investigating the roles of micrornas in biotic stress responses and functional characterization of a novel ztl-type f-box protein via virus induced gene silencing Dağdaş, Yasin Fatih; Akkaya, Mahinur S.; Department of Biotechnology (2009) Barley and wheat are the two most important crop species in Turkey. Molecular studies for increasing crop yield of these species are very important for the economic benefits of Turkey. Powdery mildew and yellow rust are the two main pathogens, infecting barley and wheat, respectively in our country and causing a great amount of yield loss each year. Till now, classical genetics studies were performed in order to develop resistant barley and wheat cultivars, but these studies have not been succesful. Therefo...
Molecular investigation of the effects of antioxidants on rat brain tissues Akkaş, Sara Banu; Severcan, Feride; Department of Biological Sciences (2003) The brain is highly susceptible to free radical damage since it is rich in polyunsaturated fatty acids and consumes very high amounts of oxygen. In this study, the effects on rat brain tissue of several antioxidants, namely lipoic acid, vitamin E and melatonin, were examined as the control studies of further research, in which their ability to protect the rat brain tissue from oxidative stress will be investigated. The tool of investigation selected was Fourier Transform Infrared Spectroscopy (FTIR) because...
Microwave-Assisted Extraction of Phenolic Compounds from Caper DURMAZ, Ezgi; Şümnü, Servet Gülüm; Şahin, Serpil (2015-09-02) In this study, it was aimed to extract phenolic compounds from caper by using microwave and to compare the results with conventional extraction. For microwave-assisted extraction, power, extraction time, solid to solvent ratio, and solvent type were selected as independent variables. Dependent variables were total phenolic content (TPC), antioxidant activity, and concentration of phenolic compounds. The increase in solvent amount increased TPC. The highest TPC was obtained by using extraction conditions of ...
The causal relationship between energy consumption and economic growth Çevirgen, Banu; Erdil, Erkan; Department of Economics (2008) The causal relationship between energy consumption and economic growth has been a controversial subject of the empirical literature. However, there is no common consensus neither on the existence nor on the direction of the causal relationship between energy consumption and economic growth. The purpose of this study is to investigate the causal relationship between energy consumption and economic growth using a consistent data set. Recently developed Granger causality tests in panel data models are used to ...
