Anatolian Medicinal Plants as Potential Antiviral Agents: Bridging Traditional Knowledge and Modern Science in the Fight Against Covid-19 and Related Viral Infections
(Tubitak Scientific & Technological Research Council Turkey, 2024) Tilkat, Engin; Jahan, Israt; Hoser, Ayse; Kaplan, Alevcan; Ozdemir, Oguzhan; Onay, Ahmet
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was the cause of the coronavirus 2019 (COVID-19), commonly known as the coronavirus pandemic. Since December 2020, COVID-19 vaccines have been extensively administered in numerous countries. In addition to new antiviral medications, the treatment regimen encompasses symptom management. Despite sustained research efforts, the outbreak remains uncontrolled, with affected patients still lacking proper treatment. This review is a valuable asset for researchers and practitioners aiming to delve into the yet unexplored potential of Anatolian flora in the fight against COVID-19 and other viral infections. Numerous medicinal plants in Anatolia, such as thyme, sage, cannabis, oregano, licorice root, and Origanum sp., contain bioactive compounds with proven antiviral properties that have been used in the region for centuries. The rich legacy of traditional Anatolian medicine (TAM), has significantly influenced modern medicine; thus, the profusion of medicinal plants native to Anatolia holds promise for antiviral drug development, making this review essential for researchers and practitioners.
Calculation Of Optimal Value Of Spinning Reserve Requirement For Unit Commitment İn Power Systems By Considering Lost Parameters;
(Gazi Universitesi Muhendislik-Mimarlik, 2019) Tür, M.R.; Ay, S.; Shobole, A.; Wadi, M.
Spinning Reserve is one of the most important sources used by system operators in response to unforeseen events such as generation discontinuities and sudden load changes. It is possible to maintain the power system against production interruptions caused by unforeseen circumstances, which can be caused by keeping the amount of reserves to be used high, in case of this process the possibility of applying the load shed decreases, but in this case reserve supply results in a very high cost. If the amount of reserves is kept low in order to reduce the cost, there will be an energy that can not be provided in the case of possible interruptions and failures, and the consumers may be left without electricity. There is a need for an economical review of these two situations in a balanced way. In this study, the requirements of the Spinning Reserve needed in the power system are determined by taking into consideration socio-economic parameters such as the amount of expected energy not supplied and value of lost load. These parameters, which are added to the cost function, are calculated for the first time in our national power system by a new method. Macroeconomic analysis has been supported for this value. Thus, considering the calculated socioeconomic parameters, a program based on benefit/cost is used to calculate the economic cost value of the reserve for the power system model. © 2019 Gazi Universitesi Muhendislik-Mimarlik.

A Detailed Review on the Green Synthesis of Selenium Nanoparticles Using Plant Extracts and Their Anticancer Applications
(Wiley-v C H verlag Gmbh, 2024) Tarhan, Tuba
Nanobiotechnology is a field of science with tremendous promising applications in cancer chemotherapy, targeted drug delivery, molecular diagnosis, and molecular imaging. Selenium, one of the critical trace elements, participates in the structure of selenocysteine protein, which plays an important role in maintaining redox balance due to its oxidoreductase activity. Elemental selenium (Se0) has significantly lower toxicity values than its oxyanions, selenite, and selenate forms. For this reason, it is important to convert elemental selenium into atomic form in biological studies. In particular, their role in regulating the immune system makes selenium nanoparticles (SeNPs) superior to others. SeNPs have been discussed effectively in the literature in anticancer activity applications. SeNPs green synthesis is focused on a more economical, biocompatible, and environmentally friendly application by using, reducing, and stabilizing agents in plants. The aim of this review is to highlight the anticancer activity applications of SeNPs synthesized with plant extracts in the last 6 years (i.e., between 2019 and 2024). In addition, it aims to shed light on the green synthesis mechanism of NPs by using plant extracts and to highlight the factors affecting green synthesis and its advantages and disadvantages.

Editorial: Anxiety, burnout, and stress among healthcare professionals
(Frontiers, 2023) Bayram Değer, Vasfiye
The technology, informatics and social fields are experiencing continuous changes and developments day by day. Such changes and developments influence human life and expand the fields of research. One of these fields is the world of work life. Work life is an area where people spend a significant part of their lives by spending time and effort. The willingness of employees to make quality use of their time and labor significantly affects the efficiency obtained as a result of their work (Burton, 2010). The nature of the work requirements and the quantity of communication with other people in the workplace create challenging situations for employees. In this context, when it comes to health in work life, health workers are seen as an important sample group in terms of researching variables in work life, since their field requires qualified labor force, is vital and is a profession that constantly involves face-to-face interaction with people. The health sector is one of the sectors where employees have the most difficulties due to various factors. The health sector differs from other working environments due to the difficulty of serving patients with severe stress and the fact that employees in this sector often face stressful situations in their daily working environment.
eVisa's impacts on travel and tourism: the case of Turkey
(EMERALD GROUP PUBLISHING LTD, 2018) Cakar, Kadir; Kalbaska, Nadzeya; Inanir, Ali; Oren, Tuba Sahin
Purpose The purpose of this study was to investigate eVisa applications. eVisa is a service that falls under eTourism, whose growing use can be attributed to its ability to simplify the process of obtaining a visa. The objectives of this study were twofold: to explore the eVisa experience of tourists who have previously visited Turkey by using the service and to analyse the perceptions of stakeholders who have contributed to eVisa. Design/methodology/approach The present research has utilised two methodologies within the context of qualitative research methods. Data were gathered from tourists by using reviews (n = 1690) and in-depth interviews key actors (n = 4), which represent consumers and contributors' perspectives on the eVisa system, respectively. While consumers dictate the demand of the service, contributors control its supply. The contributors referenced herein are relevant eVisa stakeholders in Antalya. Findings The research findings revealed eVisa facilitation's positive effects on a destination's image and tourists' intentions to revisit destinations compared to when they use traditional visa-obtaining processes. The research findings then present suitable data for destination managers and policymakers regarding eVisa facilitation, followed by this study's conclusions and implications. Research limitations/implications eVisa facilitation can foster demand for travel and tourism while maintaining bureaucratic elements of the traditional visa procedure. From a psychological perspective, eVisa facilitation can positively affect travel motivation to certain destinations where eVisas are applicable, as well as positively influence intentions to revisit tourist destinations. Originality/value The originality and uniqueness of the present study lies in its contribution to the increasing recognition of the significance and positive impacts of eVisa facilitation on travel and tourism demand.

(International Journal of Online Pedagogy and Course Design, 2021) Göksu, İdris; Koçak, Ömer; Gündüz, Ali; Göktaş, Yüksel
This study aimed to examine the bibliometric results (co-authorship, citation, co-occurrence, bibliographic coupling, and co-citation) of publications in the field of instructional design. The study includes the publications in the database of the Web of Science in the period between 1975 and 2019. It was found through co-authorship analysis that 9,344 authors who had written in the field of instructional design functioned as co-authors and had links. There were studies on an instructional design from 103 different countries. It was also found that keywords such as e-learning and online learning were frequently used and that the studies published in recent years prioritized the keywords of the massive open online courses, mobile learning, flipped classroom, gamification, and augmented reality. While the most published authors were F. Paas and J. van Merrienboer in the field, the author who was the most cited was J. Sweller.
John of phoberos, a 12th-century monastic founder, and his saints: Luke of mesembria and symeon of the wondrous mountain
(Societe des Bollandistes, 2016) Krausmüller, Dirk
Le moine Jean, abbé du monastère de Phoberos et auteur d’une règle monastique, tenait deux saints en haute estime, à savoir son prédécesseur Luc de Messembria et le stylite et abbé Syméon le Jeune (VIe s.). Si son rapport avec Luc peut se comprendre aisément, la vénération de Jean pour Syméon est, quant à elle, plus surprenante. Elle s’explique probablement par les activités littéraires des moines de la Sainte-Montagne, près d’Antioche, qui firent tout pour promouvoir leur saint patron.
Metabolic Syndrome in School Children
(TURKISH PEDIATRIC ENDOCRINOLOGY & DIABETES SOCIETY, 2013) Battaloğlu İnanç, Betül
The problem of excessive weight and obesity is increasing world-wide. According to the World Health Organization (WHO), there are over 1.6 billion overweight and 400 million obese people in the world; in 2015, these figures are expected to reach 2.3 billion and 700 million, respectively. Ninety percent of obese adolescents are at risk of becoming obese adults; 75% of obese 12-year-olds go on to become obese adults; of 7-year-olds, 41% of obese ones become obese in adulthood; 25% of those obese in the pre-school period become obese adults; and 14% of obese infants are at risk of becoming obese adults. The presence of childhood obesity increases the risk of non-communicable diseases such as metabolic syndrome (MS), type 2 diabetes mellitus (DM), hypertension (HT), hyperlipidemia, cardiovascular disease, and certain cancers (1). In clinical studies, the prevalence of MS in childhood was found to be approximately 3-4%. The aim of the present study was to evaluate the prevalence of MS in southwest part of Turkey.
Mythical Roots And Current Functions Of The Saint Stories And Legends Connected To Holy Places İn Mardin;
(Cyprus International University, 2019) Balıkçı, Ş.Ç.
Sacred values dating back to the mythic periods are born from humanity’s need to believe. Sacred places and saints who are seemed as proprietorship are occurred in many parts of Anatolia. These beliefs change region to region but they are fed from similar culture bases and they contain similar practices and beliefs for responding to the same needs. In this context, sacred places which are the subject of this study named “yatır” have narratives which are occurred around those places. But in Mardin, some sacred places are independet from saint belief and they are consired as sacred by the people of Mardin. All these places have functions like giving healty, curing infertility, protecting from harmful animals, evil spirits and magic, being fertility source. This study aims to handle the beliefs and narratives which are occured near sacred places “especially Sultan Şeyhmus” with direction of its motifs, functions and culture transmission. Central Mardin and its nearby district form basis of this research. Some of the texts in this research have been obtained by myself as either observer or participant observer while others were obtained by undergraduate students and sent to me in writing. All the necessary permissions regarding the texts were obtained from both the original sources and the compilers whose contact information were available under the compiled texts. When the stories and legends in this research are examined, it is seen that they are founded on old Turkish beliefs and traditions. Today, however, these foundations have been long forgotten by the sources who perform the practices. It has also been determined that Islamic faith, other monotheistic religions and old Turkish beliefs have gained new dimensions and these sacred places have been transformed into centers where they meet the sipiritual needs of the people. © 2019 Cyprus International University.

Natural phytotherapeutic antioxidants in the treatment of mercury intoxication-A review
(Tabriz University of Medical Sciences, 2018) Unsal V.
Heavy metals taken into the organism can make the toxic effects on the metabolism in various ways. For example, they may interact with proteins to alter and inhibit their enzymatic and structural functions. Mercury is one of the toxic elements that are widely distributed in nature. Mercury toxicity poses a serious threat to human health. It is an element that causes oxidative stress to increase in individuals, leading to tissue damage. Oxidative stress is the result of the imbalance between the production of oxidative species and cellular antioxidant defense. Phytotherapy continues to play an important role in health care. Natural phytotherapeutic antioxidants, exhibit a broad sequence of biological impacts, including anti-oxidative stress, anti-aging, anti-toxicicity and anticancer. Many studies have also shown that the phytotherapeutic agents play an important role in the removal of mercury from the tissue and in reducing oxidative stress. Our goal in this review was to investigate alternative ways of extracting the mercury in the tissue. © 2018 The Authors.

(SPRINGER WIEN, 2013) Ozdemir, Sadin; Okumus, Veysi; Dundar, Abdurrahman; Kilinc, Ersin
This review (160 refs). covers the current state of the art of microbacteria-based sorbents for preconcentration of metal ions at trace levels. We highlight advantages and major challenges of the techniques and discuss future perspectives of both batch and column-based methods. Particular attention is paid to the preconcentration of metal ions using resin-immobilized microbacteria for solid phase extractions. We also discuss detection methods including UV-vis spectrophotometry, FAAS, ICP-OES and ICP-MS. Analytical figures of merit are compared, and examples are given for the application to a variety of samples including food, beverages, alloys, water, soil, and geological samples.
Removal of cadmium (II) in the aqueous solutions by biosorption of Bacillus licheniformis isolated from soil in the area of Tigris River
(International Journal of Environmental Analytical Chemistry, 2021) Baran, Mehmet Fırat; Duz, Mehmet Zahir
Biosorption by dead bacteria is an alternative and effective method for the removal toxic elements from drinking water and waste water. The biosorption of Cd(II) from aqueous solutions was studied in a batch method by using dead bacteria Bacillus licheniformis sp. extracted from soil in the area of Tigris River. The Cd element analysis was determined using ICP-OES and AAS. The maximum adsorption capacity of biosorbent was determined, respectively, 24.51 mg/g for Cd element from Langmuir isotherm constants in the optimum conditions. The characterisation of B. licheniformis to describe behaviour of bacteria was determined such as adsorption isotherm, kinetic and thermodynamic data using FT-IR, TGA, DTA, SEM and EDX. The results suggested that the most equilibrium data of Cd(II) bioadsorption was best represented by the pseudo second-order equation and Langmuir isotherm model at different time-temperatures. The thermodynamic functions and activation energy was found to be ΔG°; −0,984 kJ/mol at 318 K, ΔH°; 15.48 kJ/mol, ΔS°; 39.08 kJ/mol and Ea; 23.24 kJ/mol and due to the ΔG°< 0, ΔH°> 0, ΔS°> 0, the reaction mechanism was determined to be physical adsorption and endothermic. This study shows that B. licheniformis sp. can be used as an effective method for the removal of Cd(II) from aqueous solutions.
Service robots as a tool for physical distancing in tourism
(Current Issues in Tourism, 2021) Seyitoğlu, Faruk; Ivanov, Stanislav
COVID-19 pandemic is affecting negatively the tourism and hospitality industry. As people must avoid physical interaction, service robots can be a useful tool to ensure a high level of physical social distance during the epidemic. This paper discusses whether the application of service robots to provide physical distance in the tourism and hospitality context is going to be beneficial or there will be side effects as well. The paper posits that service robots create a technological shield between tourists and employees that increases the physical and emotional distance between them.
