Symmetric and asymmetric volatility: Forecasting the Borsa Istanbul 100 index return volatility
Authors: Öner Selma , Öner Hakan 
Published: March 2023

Abstract
The development of technology and the globalization of financial markets have increased the volatility in financial markets and caused the emergence of risks and uncertainties that have not been previously encountered. Since traditional econometric models cannot fully explain this volatility, nonlinear conditional variance models such as ARCH, GARCH, EGARCH and TARCH are used today. From this point of view, this study aims to determine the most explanatory model that fund managers who are considering investing in the Borsa Istanbul 100 (BIST 100) Index, and academicians doing research on this subject, can use in estimating the BIST 100 Index return volatility. For this purpose, ARCH and GARCH models, as symmetric models, and EGARCH and TARCH models, as asymmetric nonlinear conditional models, are included in the econometric analysis by using the end-of-day values of 2657 observations belonging to the 04.01.2010-28.07.2020 period. According to the empirical results of the study, the TARCH model, which has the highest level of explanatory power, gives the most successful results among related models in revealing BIST 100 Index return volatility.
Relationship between the green finance index, CO2 emission, and GDP
Authors: Hamurcu Çağrı 
Published: March 2023

Abstract
Green technology innovation and effective use of green financing tools are very important in order to ensure sustainable economic and environmental development without environmental degradation, and to decarbonize all sectors. Evaluating the green investment process together with the inputs, outputs and the factors involved in the process will make important contributions in terms of determining the current situation, developing new and effective policies and raising awareness on green finance. For all these reasons, it is aimed to reveal the interaction mechanisms between GFI, CO2 emissions and GDP in this study. GFI, CO2 emissions, and GDP variables covering 26 countries between 2018-2021 were analyzed using panel data analysis with a fixed effects model. Firstly, it is found that CO2 emission had a negative effect on GFI, but GDP had a positive effect on GFI, and the effect of CO2 was greater than GDP. Secondly, GFI was found to have negative effects on CO2 emissions whereas GDP had positive effects, with GFI benefiting slightly more than GDP from these effects. Thirdly, GDP was shown to be positively affected by both GFI and CO2, and the analyses revealed that the effect of CO2 was much greater than that of GFI. The findings are considered important in terms of making predictions in terms of understanding and developing green finance and its effects.

Abstract
Separation among rubidium and potassium ions from salt lake brines remains challenging. In this work, a typical room temperature ionic liquid 1-ethyl-3-metyhlimidazaolium bis(trifluoromethylsulfonyl)imide ([C2mim+][NTf2
–]) was used as diluent and synergistic extractant, dicyclohexano-18-crown-6 (DCH18C6) was used as extractant to extract rubidium ions from brine solutions which contain high concentrations of potassium ions was investigated. Under the optimal conditions, the single extraction efficiency of rubidium ions was up 93.63%. The thermodynamic parameters of the rubidium ion extraction were obtained. Based on the slope analysis method, the extracted species in the organic phase were ascertained as 1:1 complex. UV-visible has been performed to investigate the ion concentration of ionic liquid before and after the interaction of metal ions and ligands. Rubidium ions in [Rb · DCH18C6]+ complex were stripped by 2.5 mol · L–1 NH4NO3. The extraction system offers high efficiency, simplicity and environmentally friendly application prospect to separate rubidium from brine solutions.

Abstract

Background: COVID-19 is a disease in several stages starting with virus replication to dysregulation in immune system response, organ failure and recovery/death. Our aim was to determine the effect of Ganoderma lucidum, lycopene, sulforaphane, royal jelly and resveratrol extract on markers of oxidative stress, inflammation, routine laboratory analyses and duration of symptoms in COVID-19 patients.

Methods: The oxidative stress parameters and interleukines 6 and 8 (IL-6, IL-8), tumor necrosis factor alpha (TNF-α) were determined in order to estimate the antioxidant and the anti-inflammatory effect of the product using a spectrophotometric and a magnetic bead-based multiplex assay in serum of 30 patients with mild form of COVID-19.

Results: Statistically significant differences were obtained for all investigated parameters between the treated patients and the control group. Moreover, significant differences were observed for leukocytes, neutrophil to leukocyte ratio and iron. The average duration of the symptoms was 9.4±0.487 days versus 13.1±0.483 days in the treatment and the control group, respectively (p=0.0003).

Conclusion: Our results demonstrated the promising effect of Ge132+NaturalTM on reducing the oxidative stress and the IL-6, IL-8 and TNF-α levels, and symptoms duration in COVID-19 patients. The evidence presented herein suggest that the combination of Ganoderma lucidum extract, lycopene, sulforaphane, royal jelly and resveratrol could be used as a potent an adjuvant therapy in diseases accompanied by increased oxidative stress and inflammation.
Chronic Diseases in Children as a Challenge for Parenting
Authors: Pop-Jordanova Nada 
Published: March 2023

Abstract
To be a parent or a caregiver in a modern society is a very difficult task, including multiple demands and expectations. Parenting imposes a special role in the life of any couple, especially for the mother, roles which must be learned through personal education, enriched by transgenerational experience.
Chronic disease is recognized as a large stressor that affects the current situation of a child and a child’s family. In this difficult situation, the family must go through a process of learning how to cope with it. In the family, where a child has a long-term health problem, there are certain behaviours that hinder the normal functioning of family relationships.
According to the experience of many researchers, including my own, there is an indication that a child’s illness often leads to the divorce of the parents. The fathers of sick children are often the initiators of such decisions.
The purpose of this article was to find if there are differences in parenting between mothers and fathers of chronically ill children.
The methodology is comprised of a review of published articles in PubMed over the last two decades related to parenting when there is chronic illness in children. More than 500 articles related to the topic were found. Obtained results were discussed.
Current Approach to Renal Transplantation Candidates and Potential Donors with Viral Hepatitis
Authors: Korucu Berfu , Ulu Sena , Gungor Ozkan 
Published: March 2023

Abstract
Renal transplantation is the most beneficial treatment in patients with chronic kidney disease (CKD), increasing life expectancy and improving quality of life. A better understanding of organ and tissue functions, the development of surgical techniques, and new and effective immunosuppressive and antimicrobial drugs increase the success of transplantation. However, the number of renal transplantations from living and cadaveric donors is not at the desired frequency. Among the leading causes of the restrictions for transplantation are both the recipients’ and donors’ chronic diseases. While hepatitis B and C infections are a significant problem affecting the number and success of renal transplantations, the innovation of hepatitis C virus treatments has improved outcomes. Thus, the recipient and donor hepatitis B and C virus infections are no longer considered as relative contraindications for renal transplantation. This review discusses the management of patients and donors with hepatitis B and hepatitis C in renal transplantation.
