“…The Volatility graph shown in Figure 3 also shows that there is not much difference between the two indices. Gök and Özdemir (2017) found similar results in their work. According to the findings in their study, the conditional volatility of both indices is very close to each other and they exhibit a similar behavior.…”

Mass production, which started with the industrial revolution, caused both the unconscious consumption of the resources and the damages to the ecological system after the production. In this respect, the concept of sustainability, which is one of the most important conception of responsibility, is gradually gaining value in terms of protecting resources and transferring them to future generations. (Mori and Christodoulou, 2012: 94-106). Sustainability In the first place, it has started to be used mostly in the management of natural resources; later, it was used in different fields such as sectoral practices and energy tourism (Diaz - Baltciro, Voces, Romero, 2011: 761-773). Today, the expectations of the society from the enterprises have changed compared to the past. These changing expectations lead businesses to new searches. The most important concept that guides these quests is to be sustainable. The concept of sustainability for enterprises gains a new dimension in the form of corporate sustainability”. For corporate sustainability, it is possible for organizations to achieve individual results only to a certain extent. Because companies are affected to a great extent by all kinds of economic, social and even cultural formations occurring in their environment (Kuşat, 2012: 238). The most important benefit of sustainability indices is that it leads to improvements in transparency without the need for regulations, better understanding of the social and environmental impacts of companies and guiding them to reduce the negative effects of company activities. The BIST Index serves as a guide for companies on what to measure, what needs to be developed and what can be explained. Thus, it creates opportunities for companies to see social and environmental risks and opportunities and to manage their sustainability performances correctly. The index, on the other hand, provides information to investors and the community about the sustainability performance of companies. The aim of this study is whether the BIST Sustainable Index makes a difference for companies compared to BIST 100. "Does the BIST Sustainability Index really make a difference?" will be examined. In this context, data between 2014-2018 of BIST Sustainability and BIST 100 index will be examined. Based on the results obtained in the study, it shows that there is no strong evidence of the impact of inclusion in the BIST Sustainability Index on the stock returns of companies. At the same time, the BIST Sustainability Index has been shown to have similar returns to the BIST 100 Index. Key Words: Sustainability Index, BIST, Corporate.

“…The density of lipoprotein molecule depends on the amount of cholesterol and triglyceride binding to the protein 4. Lipoprotein (a) has been found to be a new independent factor associated with cardiovascular diseases 5. Lipoprotein (a) is similar to low-density lipoprotein (LDL-chol); however, it has a lipoprotein (a) plasminogen-like structure due to the disulfide bridge.…”

IntroductionThe aim of this study was to investigate whether estradiol (E2), E2 combined with progesterone (Prog) (E2/Prog), and genistein (Gen) treatment had antioxidative and anti-hyperlipidemic effects in the plasma of ovariectomized (OVX) rats.Materials and methodsAdult female Sprague–Dawley rats were divided into five groups. Rats in all groups, except for those in a sham group, underwent bilateral ovariectomy under general anesthesia. The groups were as follows: sham group; control OVX group; group treated with estrogen (0.014 mg/kg 17-β E2); group treated with a combination of E2 and Prog (0.014 mg/kg 17-β E2 plus 0.028 mg/kg drospirenone), and group treated with Gen (10 mg/kg/day). Plasma of rats of each treatment group was analyzed to determine the total antioxidant status, total oxidant status, paraoxonase activity, lipid profile, high-density lipoprotein (HDL-chol), low-density lipoprotein (LDL-chol), total cholesterol (Total-C), triacylglycerols, lipoprotein (a), and oxidative stress index.ResultsPlasma Total-C levels and body weight increased in all the OVX groups compared with the sham group (P<0.005). The group treated with E2 had significantly elevated total oxidant status, oxidative stress index, LDL-chol, and Total-C compared with the control group (P<0.005). Gen treatment might lead to lower LDL-chol and Total-C levels compared with E2 treatment.ConclusionsGen treatment might be preferred to E2 treatment for treatment of menopausal symptoms in patients at risk for cardiovascular diseases. However, considering the small sample size of this study, larger studies are needed in this area.

“…The results did not show any difference in the rate of return between indices while the market to book value ratio of listed companies was higher than non-listed companies. Gok and Özdemir [47] aimed at comparing the performance of XSURD and BIST 100 indices based on Sharpe Ratio and Jenson Alpha Coefficient as well as determining the volatility structures of both indices by using daily closing values between 2014 and 2016. It was found that the Sharpe Ratio of XSURD Index was higher than the BIST 100 Index.…”

This study aims at empirically investigating the volatility and shock transmission patterns between the BIST 100 Index and the relatively new BIST Sustainability Index, which is a platform for companies with high performance on the international sustainability criteria. Utilizing 678 daily data from 05/11/2014, the day the XSURD Index was launched, to 31/08/2017, the analysis employed a bivariate BEKK-GARCH (1,1) model. The findings indicate the existence of bidirectional volatility spillovers between two indices. Additionally, current volatility is affected by its past volatility for each index. As for the shock transmission, the BIST Sustainability Index is responsive to both its shocks and shocks arriving from the BIST 100 Index. However, the BIST 100 Index responds only to its shocks without any significant shock transmission from the BIST Sustainability Index.
