Şakar, Murat; Bayındır, Melek; Kılıç, Tahir
Study Objectives: This study aimed to examine the body perception levels of women aged between 11 and 14, including those not playing sports and playing sports according to their sports branches. Method: the study was carried out with 140 female participants between ages 11 and 14. The study group consists of 80 licensed women athletes playing volleyball (n:28), basketball (n:25), badminton (n:9), and swimming (n:18) and also 60 women who are educated in the same school but do not actively play sports. Participants were included in the study voluntarily. The data were measured for the 2017-2018 academic calendar by using the “The Multidimensional Body-Self Relations Questionnaire (MBSRQ)”. The Turkish validity and reliability of this scale were performed. Results: The appearance orientation scores of individuals who play individual and team sports were found to be significantly lower than those who do not. It was observed that there was a significant difference in the body perception levels of women playing and not playing sports. Moreover, there was a significant difference between the fitness evaluation, fitness orientation, and overall scale scores according to age, branch, and sports status. On the other hand, there was no significant difference between the scores of appearance evaluation, health orientation, body areas satisfaction, appearance orientation, and health evaluation. Conclusion: The formation of a positive body image can be achieved by actively participating in sports and physical activities in adolescence. It should be encouraged as a state policy that adolescents participate in social sportive communities where they can establish healthy relationships. To have adult behaviors and to struggle with life, for individuals with reduced anxiety levels, high self-esteem and self-confidence, and satisfaction with their body image, organized planning and precautions should be performed to adapt them to life.

The pollen morphology of eight endemic species of the genus Inula L. (Asteraceae)–I. helenium subsp. orgyalis (Boiss.) Grierson, I. helenium subsp. vanensis Grierson, I. macrocephala Boiss. & Kotschy ex Boiss., I. discoidea Boiss., I. sarana Boiss., I. fragilis Boiss. & Hausskn., I. anatolica Boiss. and I. sechmenii Hartvig & Strid–distributed in Turkey was studied with light microscopy and scanning electron microscopy. We found that the pollen of these Inula taxa are prolate-spheroidal in shape (except in Inula discoidea), with the polar axis ranging from 19.18 to 33.14 µm and the equatorial diameter ranging from 18.54 to 32.92 µm. The pollen grains are tricolporate and their ornamentation is echinate. The exine thickness ranges from 0.87 to 2.07 µm. As this study demonstrates, results of Principal Component Analysis are revealed that some of the pollen characters, such as spine length and width, are significant morphological characters for taxonomic discrimination of the eight endemic Inula taxa. According to cluster analysis, two main groups of examined taxa are constituted.

Butt, Ghazala; Ozbey, Ulku; Malik, Durrshahwar; Attar, Rukset; Youssef, Lara; Farooqi, Ammad Ahmad
Natural products have historically been invaluable as a premium source of therapeutic agents. Recent advancements in genomics and structural biology have portrayed a high-resolution landscape of the diversity of proteins targeted by pharmacologically active products from natural sources. Natural product research has generated valuable wealth of information and cutting-edge research-works have leveraged our conceptual knowledge altogether to a new level. Wogonin (5,7-dihydroxy-8-methoxyflavone) is an O-methylated flavone and has attracted noteworthy appreciation because of its ability to pharmacologically target plethora of cell signaling pathways in different cancers. In this mini-review, we have gathered scattered pieces of available scientific evidence to summarize how wogonin pharmaceutically targeted Wnt/β-catenin, JAK/STAT, VEGF/VEGFR and TRAIL-driven apoptotic pathways in wide variety of cancers. We have also critically analyzed how wogonin prevented carcinogenesis and metastasis in tumor-bearing mice. Although researchers have uncovered pleiotropic role of wogonin in the regulation of different oncogenic signaling cascades but there are visible knowledge gaps in our understanding related to regulation of non-coding RNAs by wogonin. Future studies must converge on the unraveling of additional drug targets for wogonin to achieve a fuller and realistic understanding of the chemopreventive properties of wogonin.

Gürler, Nedim; Torğut, Gülben
In this study, PSG composite films were prepared by casting method by adding graphene (G) to glycerol plasticized potato starch (PS) films. The structure and properties of the composite films were investigated attenuated total reflectance Fourier transform infrared (ATR-FTIR), X-ray analysis (XRD), and swelling capacity, total soluble matter, transparency, tensile strength, and electrical conductivity. When the G content of PSG composite films increased from 0% to 1%, tensile strength increased from 1.035 MPa to 1.681 MPa, but decreased to 1.175 MPa in composite films containing 2% G. It also increased electrical conductivity when the G concentration increased. Also, the G layers are among the PS films and their swelling and solubility properties are reduced. With increased G concentration, the light transmittance decreased and the films were more opaque. These improvements can refer to the interface interaction between PS and G.

Background/aim: This study was conducted to elucidate the effects of lutein/zeaxanthin isomers (L/Zi) on lipid metabolism, oxidative stress, NF-κB/Nrf2 pathways, and synaptic plasticity proteins in trained rats. Materials and methods: Wistar rats were distributed into four groups: 1) control, 2) L/Zi: rats received L/Zi at the dose of 100 mg/kg by oral gavage, 3) exercise, 4) exercise+L/Zi: rats exercised and received L/Zi (100 mg/kg) by oral gavage. The duration of the study was eight weeks. Results: Exercise combined with L/Zi reduced lipid peroxidation and improved antioxidant enzyme activities of muscle and cerebral cortex in rats (p < 0.001). In the Exercise + L/Zi group, muscle and cerebral cortex Nrf2 and HO-1 levels increased, while NF-κB levels decreased (p <0.001). Also, L/Zi improved BDNF, synapsin I, SYP, and GAP-43 levels of the cerebral cortex of trained rats (p < 0.001). The highest levels of BDNF, synapsin SYP, and GAP-43 in the cerebral cortex were determined in the Exercise+L/Zi group. Conclusion: These results suggested that exercise combined with L/Zi supplementation might be effective to reduce neurodegeneration via improving neurotrophic factors and synaptic proteins, and oxidative capacity in the cerebral cortex.

Free radicals are responsible for many health problems, especially oxidative stress-related diseases. With conscious nutrition and the use of natural antioxidants, it is now possible to cope with these diseases or minimize their effects. The aim of this study was to determine pH, total acidity, total SO2, free SO2, relative SO2, dry matter, density, alcohol content, reducing sugar, ash, CUPRAC, DPPH free radical scavenging capacity, total phenolic content, elemental composition, and some phenolic compounds of Syriac (Mardin) wines. Estimated daily intake (EDI), target hazard quotients (THQ), total target hazard quotients (TTHQ), and relative risk (RR) were calculated, to assess a health risk resulting from regular consumption of Syriac wines. The elements EDI values through consumption of wines were less than the recommended dietary allowance values. Obtained THQ values were less than 1. When the obtained results are compared with the levels set by regulatory authorities, the investigated wine consumption does not pose a toxicological risk based on EDI, THQ, TTHQ, and RR values. In addition, this study showed that the Syriac wine’s antioxidant capacities are high and rich in phenolic compounds and elements.

Ince, Olcay K.; Aydogdu, Burcu; Alp, Hevidar; Ince, Muharrem
In the present study, novel chitosan coated magnetic magnetite (Fe3O4) nanoparticles were successfully biosynthesized from mushroom, Agaricus campestris, extract. The obtained bio-nanocomposite material was used to investigate ultra-fast and highly efficient for removal of Ni2+ ions in a fixed-bed column. Chitosan was treated as polyelectrolyte complex with Fe3O4 nanoparticles and a Fungal Bio-Nanocomposite Material (FBNM) was derived. The FBNM was characterized by using X-Ray Diffractometer (XRD), Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Fourier Transform Infrared spectra (FTIR) and Thermogravimetric Analysis (TGA) techniques and under varied experimental conditions. The influence of some important operating conditions including pH, flow rate and initial Ni2+ concentration on the uptake of Ni2+ solution was also optimized using a synthetic water sample. A Central Composite Design (CCD) combined with Response Surface Modeling (RSM) was carried out to maximize Ni2+ removal using FBNM for adsorption process. A regression model was derived using CCD to predict the responses and analysis of variance (ANOVA) and lack of fit test was used to check model adequacy. It was observed that the quadratic model, which was controlled and proposed, was originated from experimental design data. The FBNM maximum adsorption capacity was determined as 59.8 mg g−1. Finally, developed method was applied to soft drinks to determine Ni2+ levels. Reusability of FBNM was tested, and the adsorption and desorption capacities were not affected after eight cycles. The paper suggests that the FBNM is a promising recyclable nanoadsorbent for the removal of Ni2+ from various soft drinks.

The biochemical biomarkers (Catalase (CAT), glutathione s-transferase (GST), cytochrome P4501A1 (CYP1A1450) activities and glutathione (GSH), malondialdehyde (MDA) levels) of D. polymorpha exposed to the basic blue 41 (BB41) solutions for 24 and 96 h before and after the Fenton process (FTP) were evaluated to investigate the efficiency of the FTP. The optimum conditions for the removal of BB41 were set using central composite design (CCD), which is a response surface methodology (RSM) module in the Design-Expert® software. The optimal conditions were found to be 27.87 min, 3.49 mg/L, and 0.04 for reaction time, initial BB41 concentration, and Fe2+/H2O2 molar ratio, respectively, resulting in maximum (99%) removal efficiency. After FTP, the MDA and GSH levels decreased significantly during the 24 and 96 h. CAT activities were increased after treatment. No statistically significant changes were observed in the CYP1A1 levels after FTP. GST activities decreased during 24 h but increased during 96 h after FTP. CYP1A1450, catalase, GST activities and MDA, GSH levels of D. polymorpha are useful biomarkers to evaluate the efficiency of FTP. This study suggests that BB41 dye must be further treated after the FTP to minimise the ecotoxicological risk.

Gul, Muhammet; Mete, Suleyman; Serin, Faruk; Celik, Erkan
This chapter aims at the adaptation of the Fine–Kinney occupational risk assessment concept into the VIKOR multi-attribute decision-making method with an interval-valued Pythagorean fuzzy set. The classical fuzzy set theory has been improved by proposing a number of extended versions. One of them is the Pythagorean fuzzy set. It has been firstly developed by Yager (IEEE Transactions on Fuzzy Systems 22:958–965, [1]). In this chapter, we use this type of fuzzy set with VIKOR since it reflects uncertainty in occupational risk assessment and decision-making better than other fuzzy extensions. To demonstrate the proposed approach applicability, a case study regarding the activities of the surface treatment area in a chrome plating unit of a gun factory is performed. Some additional analysis to test the solidity and validity of the approach is executed. Finally, the Python codes in the implementation of the proposed approach are given for scholars and practitioners for usage in further studies.

Garlic has an important place in daily nutrition. It is consumed by people because of its antimicrobial, antibacterial, and antioxidant properties, and it is also known to be good for many diseases. Along with these properties of garlic, its fatty acid content is also important. The goal of this study is to determine the fatty acids in Allium tuncelianum (Tunceli garlic), which grows naturally in Tunceli, Turkey, by gas chromatography with flame ionization detection (GC–FID). Fifteen of 37 fatty acids studied were detected in Allium tuncelianum, and the primary fatty acids in the sample extracts were determined to be the polyunsaturated fatty acid (PUFA) linoleic acid (C18:2n6c, 41.595%) and the monounsaturated fatty acid (MUFA) oleic acid (C18:1n9c, 33.302%). Small quantities of saturated fatty acids (SAFAs) were also present, including palmitic acid (C16:0, 11.739%), henoicosanoic acid (C21:0, 6.946%), and stearic acid (C18:0, 2.362%).

In this study, the survival of Escherichia coli O157:H7 and non-O157 STEC serogroups of O26, O111, O103, and O145 were investigated during production and storage of yogurt. For this purpose, pathogens were individually inoculated into milk after pasteurization along with the starter culture (approximately 7.00±1.00 log10 cfu/g). After incubation at 44oC (about 180 min), yogurt samples were capped and stored at 4oC for 20 days. Pathogens were enumerated at 0, 5, 10, 15, and 20th days of storage. Lactic acid content (%) and pH of the samples were also screened. Moreover, mesophilic Lactococcus spp. and mesophilic Lactobacillus spp. were enumerated during production of yogurt.After incubation, the number of E. coli O157, O26, O103, O145, O111were 6.76±0.45, 6.64±0.53, 7.12±0.43, 6.00±1.39, 5.89±1.37 log10 cfu/g, respectively. A significant decrease was determined in all groups during the storage of yogurt samples at 4oC (p<0.05). It was detected on the 20th day of storage that the number of E. coli O157:H7 and non-O157 STEC serogroups of O103 and O145 were under the detection limit. However, STEC O26 and O111 were viable around 1.51±0.98 and 1.18±0.62 log10 cfu/g respectively. Results of the study showed that Escherichia coli O157:H7 and non-O157 STEC serogroups might pose a potential health risk during production and storage of yogurt.

This study reveals out detoxifying and antioxidant enzyme response of Gammarus pulex exposed/polluted to chlorpyrifos-ethyl insecticide before and after biodegradation/bioremediation by Methylobacterium radiotolerans and Microbacterium arthrosphaerae. Cytochrome P450 1A1, glutathione S-transferase, catalase, and superoxide dismutase activities in G. pulex exposed to chlorpyrifos-ethyl before and after bioremediation/biodegradation by these two bacteria during 24 and 96 h tested by using commercial ELISA kits. The activity of catalase enzyme was decreased depending on chlorpyrifos-ethyl before and after bioremediation/biodegradation the enzyme activity was increased repeatedly. Superoxide dismutase activity level increased after chlorpyrifos-ethyl exposure in 96 h (p > 0.05). Following bioremediation, superoxide dismutase enzyme activity decreased again during 24 h (p > 0.05) and increased during 96 h (p < 0.05). Statistical differences were not found in cytochrome P450 1A1 enzyme activity before and after the process (p > 0.05). No significant differences were determined during the activity of glutathione S-transferase in 24 h (p > 0.05). The activities of glutathione S-transferase were increased after exposure of chlorpyrifos-ethyl during 96 h. After bioremediation; the activity of glutathione S-transferase increased even more (p < 0.05). The results determined that activities of G. pulex at superoxide dismutase, catalase, and glutathione S-transferase are common biomarkers for revealing out the efficiency of bioremediation of chlorpyrifos-ethyl with these two types of soil bacteria.

Nanomaterials are composed of several atoms or molecules, which may be of various sizes and morphologies. Manmade nanomaterials are specially produced to take advantage of the unique properties of nanoscale. There are many metal chalcogenides with different structures and compositions such as CdSe, InAs, CdS, GaN, InGeAs, CdTe, PbS, PbSe, ZnS, Na2S, CaTe, Ti2S, and Cu2Se. The diversity of metal chalcogenides is related to the orbit of transition metals. In this chapter, new studies using chalcogenide compounds as photocatalysts were explained under the subtopics of metal chalcogenides and their properties, semiconductive nanostructures, nanomaterial production technique, chemical synthesis methods, and metal chalcogenides as photocatalysts. Novel applications of metal chalcogenide-based materials like water splitters, organic pollutant degraders, self-cleaning agents chalcogenide glasses and thermoelectric materials are explained in detail under the relevant headings. Future prospects of chalcogenides are also evaluated from a different perspective.

Gul, Muhammet; Mete, Suleyman; Serin, Faruk; Celik, Erkan
In this chapter, we improved Fine–Kinney occupational risk assessment approach with interval type-2 fuzzy VIKOR (IT2FVIKOR). VIKOR is a compromise multi-attribute decision-making method proposed by Opricovic (1998). Similar to other compromised solution-based approaches, it considers the solution which is closest to the ideal. In this chapter, we adapted the interval type-2 fuzzy sets (IT2FSs) into VIKOR as it reflects the uncertainty well in decision-making. IT2FVIKOR algorithm under the Fine–Kinney concept provides a useful and solid approach to the occupational health and safety risk assessment. In addition to proposing this new approach, a case study is performed in a gun and rifle barrel external surface oxidation and coloring unit of a gun factory. A validation and a sensitivity analysis is also attached to this study. Finally, the proposed approach is implemented in Python.

The overall service quality level of Emergency Departments (EDs) can be improved by accurate forecasting of patient visits. Accordingly, this study aims to evaluate the use of three metaheuristic approaches integrated with Artificial Neural Network (ANN) in forecasting daily ED visits. To do this, five performance measures are used for evaluating the accuracy of the proposed approaches, including Bayesian ANN, Genetic Algorithm-based ANN (GA-ANN), and Particle Swarm Optimization algorithm-based ANN (PSO-ANN). The outputs of this study show that the PSO-ANN model provides the most dominant performance in both the training and testing process. The lowest error is obtained with a mean absolute percentage error (MAPE) of 6.3%, Mean Absolute Error (MAE) of 42.797, Mean Squared Error (MSE) of 2499.340, Root Mean Square Error (RMSE) of 49.933, and R-squared (R2) of 0.824 on the training dataset. The lowest error with an MAPE of 6.0%, MAE of 40.888, MSE of 2839.998, RMSE of 53.292, and R2 of 0.791 is also obtained on the testing process.
