Progranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0-90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100-150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process.

The purpose of this study was to reveal the differences between ACTN3 genotype (RR, RX, XX) and aerobic performance [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] in professional and regional amateur league soccer players and to reveal which of these parameters was a distinctive factor in these athletes.71 professional soccer players (age: 23.66 +/- 4.11 years; body height: 1.79 +/- 6.99 m; body weight: 76.02 +/- 6.76 kg; body fat: 11.59 +/- 3.11 %) and 62 regional amateur soccer players (age: 23.63 +/- 3.77 years; body height: 1.81 +/- 5.77 m; body weight: 76.36 +/- 7.53 kg; body fat: 15.60 +/- 4.65 %) volunteered for the study. After DNA extraction from buccal epithelial cells via a commercial kit was performed for the genetic background of the athletes, Real-Time PCR was carried out for genotyping. Furthermore, Yo-Yo IRT1 test was performed to determine the aerobic performance of the soccer players. SPSS 23 (SPSS Inc., Chicago, IL, USA) package program was used for the statistical analysis of the data obtained in the tests. Shapiro-Wilk test for normality and Levene's test for homogeneity of variance were performed. Chi-Square, Independent Sample T Test and One Way ANOVA test were used in the analysis of the parameters. Statistical significance was set as p<0.05. In the study, there found no meaningful statistical significance in terms of the rs1815739 polymorphism in the ACTN3 gene between the groups (p>0.05); however, there was a statistical significance in favor of professional soccer players in terms of aerobic parameters (p<0.05). Consequently, it can be said that aerobic performance is the distinguishing factor, not the ACTN3 gene, in soccer players.

-In this study, we aimed to determine the effect of Moringa oleifera essential oil (MOEO) supplementation to rations of Japanese quail (Coturnix coturnix japonica) grown under heat stress (HS) on some adipokine (visfatin, adiponectin, and chemerin), intestinal (citrulline), 3,5,3 '-triiodothyronine (T3), thyroxine (T4), and thyroid-stimulation hormone (TSH) levels in the serum. For this purpose, 320 day-old male quail chicks were used. The study was conducted over 42 days, including a 7-d adaptation period and a 35-d experimental period. Eight trial groups were established, each including 10 quail: CT (control temperature, 25 celcius), MOEO 200, MOEO 400, MOEO 600, HSC (HS control), SMOEO 200, SMOEO 400, and SMOEO 600. Based on the results, a dose-dependent decrease was observed on days 21 and 42 in serum adiponectin and T3 in the stress and stress-free groups compared with the control group due to MOEO supplementation. The lowest decrease was observed in the MOEO 600 mg/kg dose group. In addition, an increase in stressed groups was observed when examining serum citrulline levels, while chemerin levels did not have a statistically significant effect. While the decrease in serum visfatin, T4, and TSH levels on the 21st day did not have a statistically significant effect, a significant effect was determined on the 42nd day. The addition of MOEO at 600 mg/kg to the ration may be beneficial in preventing intestinal damage and inflammation that may occur due to HS.

Oguz-Saka, Simge; Aydin, Faruk; Karsli, Orhan; Dokuz, Abdurrahman; Aiglsperger, Thomas; Miggins, Daniel P.; Sen, Cuneyt; Kandemir, Raif; Sari, Bilal; Koppers, Anthony A. P.
The eastern Blacksea magmatic arc (EBMA) in the eastern Sakarya Zone (ESZ) provides an excellent opportunity to investigate birth of an extensional intra-arc and back-arc settings in the Late Cretaceous over the Early Cretaceous northern passive margin of the Neotethys Ocean. Volcano-stratigraphy clearly shows that the Late Cretaceous volcanic activity of the EBMA occurred in two major phases. Bimodality, characterized by mafic/ basaltic rocks at the base and felsic/silicic types on top of it, is a typical feature of the lower (LVS) and upper (UVS) volcanic successions in the Giresun region of the ESZ. U-Pb and Ar-Ar ages support the volcanic suc-cession as two-stage (LVS: ca. 92-85 and UVS: ca. 83-67 Ma) bimodal volcanism. Both the volcanic successions are represented by similar rock types consisting of tholeiitic to calc-alkaline basalt-basaltic andesites and calc-alkaline to shoshonitic dacite-rhyolites. Basaltic (M1-and M2-series) and felsic/silicic (F1-and F2-series) sam-ples of the LVS and UVS have an arc-like signature with enriched large ion lithophile elements (LILEs) and light rare earth elements (LREEs) and depleted high field strength elements (HFSEs). Also, the felsic/silicic samples of the F1-and F2-series show prominent negative Sr and Eu anomalies (Eu/Eu* = 0.4 to 0.9), suggesting that plagioclase fractionation played a key role on the evolution of both felsic series. Bimodal rock series in two phases have a wide range of 87Sr/86Sr(i) (0.7048-0.7075) and 143Nd/144Nd(i) (0.5123-0.5127) ratios with var-iable epsilon Nd(i) values of-3.8 to +3.0. 206Pb/204Pb(i), 207Pb/204Pb(i) and 208Pb/204Pb(i) isotope ratios of the Giresun volcanic rocks vary in the range of 17.97-18.52, 15.55-15.65 and 37.53-38.56, respectively. Geochemical and isotopic data suggest that the parental magma of the M1-basaltic rocks were probably derived from a shallow (spinel-bearing) mantle metasomatized by slab/sediment-derived fluids. In contrast, the M2-basalts seem to have been originated from a deeper mantle source (spinel-garnet transition zone) enriched by slab/sediment-derived fluids and hydrous melts (bulk sediment) metasomatism with some contributions of lower/upper crustal materials. The least evolved basaltic samples in two phases are consistent with moderate (-10-15%) to high degree (-20-30%) partial melting of the metasomatized mantle. The silicic melts of the F1 -and F2-rocks series, on the other hand, were likely derived from melting of lower crustal materials consisting of meta-basalts/andesites and lesser amount of meta-sediments. Subsequently, these melts experienced FC +/- AFC and mixing processes during their ascent and emplacement to generate high-silica (rhyolitic) melts. Our data, combined with previous studies, suggest that two-stage bimodal volcanic rocks of the Late Cretaceous in the ESZ were formed in the transition from an extensional continental intra-arc to a back-arc setting during the north-ward subduction of the northern branch of Neotethys Ocean.

Peker, Alper Tunga; Böge, Veysel; Bailey, George S.; Wagman, Jeffrey B.; Stoffregen, Thomas A.
We investigated the perception of higher-order interpersonal affordances for kicking that emerged from lower-order personal and interpersonal affordances in the context of soccer. Youth soccer players reported the minimum gap width between two confederates through which they could kick a ball. In Experiment 1, we independently manipulated the egocentric distance of gaps from participants, and the nominal role of the confederates, either as teammates or opponents. In Experiment 2, we additionally varied the direction in which the confederates were facing, either together (i.e., into the gap) or away (i.e., away from the gap). Perceived minimum kickable gap width was larger for farther egocentric distances, when confederates were identified as opponents rather than as teammates, and (in Experiment 2) when confederates faced toward, rather than away from the gap. In both experiments, these main effects were subsumed in statistically significant interactions. We argue that these interactions reveal perception of higher-order interpersonal affordances for kicking that emerged from the simultaneous influence of lower-order affordances. The results are compatible with the hypothesis that these higher-order affordances were perceived, as such, and were not additively combined from independent perception of underlying, lower-order affordances.

The oil in low-moisture foods (LMFs) shows protective effects on bacteria during thermal processing. However, the circumstances under which this protective effect strengthens remain unclear. This study aimed to understand which step of the oil exposure to bacterial cells (inoculation, isothermal inactivation, or recovery and enumer-ation step) in LMFs can enhance their heat resistance. Peanut flour (PF) and defatted PF (DPF) were selected as the oil-rich and oil-free LMF models. Salmonella enterica Enteritidis Phage Type 30 (S. Enteritidis) was inoculated into four designated PF groups representing different oil exposure stages. It was isothermally treated to obtain heat resistance parameters. At a constant moisture content (aw,25 degrees C = 0.32 +/- 0.02) and controlled aw,85 degrees C (0.32 +/- 0.02), S. Enteritidis exhibited significantly high (p < 0.05) D values in oil-rich sample groups. For instance, the heat resistance values of S. Enteritidis in the PF-DPF and DPF-PF groups were D80 degrees C of 138.22 +/- 7.45 min and 101.89 +/- 7.82 min; however, the D80 degrees C in the DPF-DPF group was 34.54 +/- 2.07 min. The oil addition after the thermal treatment also helped injured bacterial recovery in the enumeration. For instance, the D80 degrees C, D85 degrees C, and D90 degrees C values in the DFF-DPF oil groups were 36.86 +/- 2.30, 20.65 +/- 1.23, and 7.91 +/- 0.52 min, respectively, which were higher than those in the DPF-DPF group at 34.54 +/- 2.07, 17.87 +/- 0.78, and 7.10 +/- 0.52 min. We confirmed that the oil protected S. Enteritidis in PF in all three stages: desiccation process, heat treatment, and recovery of bacterial cells in plates.

The nephrotoxicity mechanisms caused by cisplatin (CP), which is used in the treatment of different types of cancer, include several processes, such as DNA damage, apoptosis, inflammation, and oxidative stress. This study investigated the protective effects of Rhododendron luteum leaf extract (RLE) in a rat model of CP -induced nephrotoxicity. Dimethyl sulfoxide extract of RLE was prepared, and its contents were clarified using liquid chromatography-mass spectrometry (LC-MS -MS). Thirty female Wistar Albino rats were divided into five different groups and sacrificed on the seventh day. Biochemical and histopathological analyses were then performed. The presence of quercitrin, quinic acid, chlorogenic acid, protocatechic acid, isoquercitrin, and quercetin was detected in the RLE. While CP significantly increased the levels of oxidative stress, inflammation, and apoptosis markers in the rat kidney tissue and blood samples, treatment with RLE significantly reversed the levels of these parameters in a dose-dependent manner. Total antioxidant status (TAS) values and glutathione (GSH) levels increased significantly in the serum samples from the treatment group compared to the CP group, while blood urea nitrogen (BUN), creatinine, oxidative stress index (OSI), tumor necrosis factor-alpha (TNF-alpha), malondialdehyde (MDA) and total oxidant status (TOS) values decreased significantly. GSH levels increased significantly in the treatment group compared to the CP group, while TNF-alpha, caspase-3 (Casp-3), 8-hydroxy-2'-deoxyguanosine (8-OHdG), OSI, TOS, MDA levels, and damage scores decreased significantly at histopathological examination. In conclusion, RLE exhibited strong protective effects against nephrotoxicity and oxidative damage caused by CP in rats.

Gundogdu, Ali; Bozbeyoglu, Pinar; Imamoglu, Mustafa; Baltaci, Cemalettin; Duran, Celal; Bulut, Volkan N.
A promising new activated carbon (AC) was produced from corncobs (CCs) by boric acid-based chemical activation to remove methylene blue (MB) as an organic pollutant and cadmium ions (Cd2+) as an inorganic pollutant from aqueous solutions. After the produced activated carbon (CCs-AC) was characterized, the adsorption mechanism of CCs-AC, which is one of the most interesting topics in the literature, was the primarily focus. The possible adsorption mechanisms of Cd2+ and MB on CCs-AC from aqueous solutions are discussed with respect to pH, thermodynamic values, and regeneration parameters. The results show that the adsorption of Cd2+ on CCs-AC was favorable at pH values higher than 4. In contrast, the adsorption process was almost pH-independent for MB. Variation of pH showed that the adsorption of Cd2+ on CCs-AC primarily occurs by electrostatic interaction. However, MB adsorption may also involve pi-pi dispersion forces and partial hydrogen bonding. The Cd2+ adsorbed on CCs-AC was quantitatively desorbed by HCl, whereas MB was not desorbed quantitatively by any solution. While a temperature increase has a positive effect on the adsorption of both methylene blue and Cd2+, the thermodynamic results show that MB adsorption is primarily chemisorption (Delta H of 24.28 kJ/mole), while Cd2+ adsorption is mostly physisorption (Delta H of 7.20 kJ/mole). Using Langmuir adsorption isotherms, the MB adsorption capacity of CCs-AC, which primarily has a microporous structure, was 0.88 mmol/g, while the Cd2+ adsorption capacity was 1.28 mmol/g.

Introduction: Patients do not feel competent in managing their post-heart surgery processes. They need access to the right information to manage their symptoms. A mobile app is the right tool for this process, with its accessibility and reminder features at any time. We investigated the effects of 4-week mobile app training on respiratory functions and maintenance of drug compliance in patients after heart surgery. Material and methods: This paper reported the findings of an experimental study, which recruited a total of 120 participants of whom all underwent heart surgery. The following outcomes were measured: TriFlo results, the Morisky Questionnaire - self-reported measure of adherence, and results of the Symptom Interpretation Questionnaire. Results: All groups showed a significant difference in Symptom Interpretation Scale subscales after using the mobile app. When the results of the research are evaluated, it can be said that there is a need for nurses to produce new-generation technological equipment to meet the needs of new products to be used in the field of health. Conclusions: Individuals can solve their post-operative symptom management problems with a mobile app. The use of a mobile app positively contributes to the management of the 2 most common symptoms after heart surgery. Mobile apps are used in many disease processes in the world. The results of these studies contribute to the limited information presenting results regarding drug compliance and lung capacity in patients with a bypass between mobile apps.

Solar collectors are frequently used in domestic water heating applications. In the design stage, the positioning of solar collector with suitable title angle is important in order to utilize from sun energy efficiently. In this study, the effect of tilt angle of a solar collector located to Erzincan city on monthly/daily average radiation values, water outlet temperature, energy and exergy efficiencies are theoretically investigated. It is seen that the maximum and minimum values of optimum tilt angles are 63 degrees ve 0 degrees for December and June, respectively. Tilt angles which are suggested for Erzincan (27.14 degrees) and calculated are compared for daily average hourly radiation values and it is seen that the maximum variation is 26% for January. In addition, energy and exergy efficiencies of solar collector are estimated and the maximum efficiencies are determined as 74.2% ve 9.7% for optimum tilt angles.

Ozyurt, E.
This study numerically investigated the elevated temperature resistance of earthquake-damaged square hollow section (SHS) T-joints subjected to brace axial compressive load. The residual stresses and deformations due to the earthquake were obtained from a pushover analysis. The extensive numerical simulations were analyzed using nonlinear finite-element software to examine the effects of the beta ratio, gamma ratio, damage level ((D) over cap), and initial applied load (n(f)) on the fire resistance of SHS T-joints after verification of the numerical simulations based on the available test results in the literature. The results indicated that the fire resistance of SHS T-joints with axial compressive load in the brace member decreased significantly due to the residual stresses and deformations from the earthquake. This situation worsened in all numerical models as the damage level increased. The reduction rate of the critical temperature at various damage rates was independent of the initially applied load ratio, but the loading rate directly affected the fire resistance of the joint regardless of the earthquake. As the beta ratio decreased, the yielded area at the brace-to-chord intersection region increased. Thus, the critical temperature of the joints at a constant damage level was inversely proportional to the beta ratio. Joints with a large gamma ratio had larger residual stresses and deformations than those of corresponding joints with a small. ratio. Therefore, the fire resistance of the joints after the earthquake decreased as the chord-wall thickness decreased. The critical temperature of the joints with either a large beta or gamma ratio was limited by the deformation limit at high damage levels. The fire resistance of the SHS T-joints after the earthquake decreased due to residual stresses and deformations. That effect increased even more in joints with high beta and. ratios.

Recepoglu, Mursit
This study has examined the causality relationship between public expenditures, economic growth and income inequality for transition economies called the Commonwealth of Independent States (CIS). In the study, in which the 1998-2019 period was analyzed, the effects of public expenditures on economic growth and income inequality were determined with the bootstrap panel causality test. Bootstrap panel causality test results show that there is a one-way causality relationship from public expenditures to economic growth for Armenia, Belarus, and Kazakhstan. On the other hand, a one-way causality relationship has been determined from public expenditures to income inequality in Belarus and Kazakhstan, and from income inequality to public expenditures in Kyrgyzstan. In Moldova and Russia, however, no causal relationship could be obtained between the variables. The overall evaluation of the findings obtained from the panel causality tests concluded that public expenditures in CIS member countries are closely related to both economic growth and income inequality. CIS member countries need state interventions in order for the market system to fully settle in transition period. However, implementing policies that do not exclude private investments and do not harm the functioning of the market economy should be elaborated during practicing public expenditure policies in these countries in transition.

Tuncay, Birgul; Göger, Berrin
Objective: This study aimed to assess the digital game addiction and sleep quality in adolescents and examine the relationship between them. Materials and Methods: This descriptive study was conducted with 312 students from three high schools located in a district center in the Eastern Black Sea Region, who agreed to participate in the study. Data were collected using the descriptive information form, the digital game addiction scale, and the Pittsburgh sleep quality index. Results: The mean age of the participants was 15.99 +/- 0.85 years. Of the participants, 78.5% played digital games on computers, mobile phones, tablets, or game rooms. The mean score of the participants on the digital game addiction scale was 12.46 +/- 5.57; 16.3% were game addicts. The Pittsburgh sleep quality index mean score was 4.72 +/- 2.53, with a score range of 0-13; 34.9% had poor sleep quality. Conclusion: In conclusion, a positive, low-level, statistically significant relationship was found between the digital game addiction scale and Pittsburgh sleep quality index scores (r=0.157, p <= 0.001). As the digital game addiction scores increase in adolescents, their sleep quality scores also increase. Game addiction and sleep-related problems in adolescents can negatively affect their physical and psychological health and academic success. Adequate supervision and protective measures are required to reduce the problems faced by adolescents when using digital technology.

As a result of the research, a significant result could not be reached in FVC and FEV1 values between Tests, Groups and Group x time intervals, whereas VC was only between tests. However, statistically significant differences were found between MVV and VC Tests, Groups and Group x Time values. In short, it has been shown that students who take swimming lessons have statistically higher lung volumes than students who do not take the lesson. However, swimming activity can be recommended to increase respiratory efficiency of university students.

Demir, Sertac Timur
In this article, everyday technology, which tends to expand without limits, is discussed in the context of contemporary practices that start from antenatal to death and that correspond to the desire for immortality of modern man. For this purpose, it is examined how technology intervenes in life and death through the episodes of Arkangel, Right Be Back, and San Junipero in Black Mirror, the popular science fiction series. In this study, the current social and human dilemmas that appear in the narratives are discussed, without ignoring the technical analysis of the series. In this respect, gene based medical studies that reformat the body, smart and synthetic technologies that add a new dimension to digital control and surveillance, contemporary medical and technoscientific assumptions about death and immortality are debated. The theoretical framework of this article consists of theoreticians such as Jean Baudrillard, David Le Breton and Byung Chul Han who consider that the change in social structure and relations is mainly driven by technology and critically approach this unavoidable trend. According to the main argument and inference of this research, technologies that can descend to every part of the body are no longer just the comfort and convenience extensions of daily lite, and they affect almost all ontological processes between existence and extinction by being articulated with human destiny. However, this global trend is also the loss of the natural and the real for the modern characters who are deprived of the human conditions such as pain and death that make life precious.

Khan, Alam
This article deals with a brief study of the history of the emergence of mukhtalifu'l-hadith science and its literature, as it is one of the most important types of hadith science that fuqaha`a and muhadithun need it in the deducing of the primary and secondary provisions and the explaining of the Prophetic hadiths. It includes a detailed comparative study between the approach of Hafiz bn. Hajar al-Asqalani al-Shafi`i (d. 852/1449), and Badru'd-Din al-`Ayni al-Hanafi (d. 855/1451) in the interpretation of mukhtalifu'l-hadith through Fathu'l-Bari and `Umdatu'l-Qari. it was clarified that each of them was exposed to the study of seemingly contradictory texts in the folds of the explanation of the hadiths of al-Bukhari and expanded on it and excelled in it. In addition, a glance has been shed in this article on the differences of muhadithun and fuqaha`a among the Hanafis scholars in arranging the ways of pairing in the interpretation of mukhtalifu'l-hadith in general, and Ibn Hajar al-Asqalani and Badru'd-Din al-`Ayni in particular. It has been proven from the application of examples from Fathu'l-Bari and `Umdatu'l-Qari that Ibn Hajar does not expand on abrogation if it is possible to combine it, unlike Badru'd-Din al-`Ayni.

Kaya, Asli Uner
Some philosophers of mind claim that non-reductionist physicalist theories of the mind cannot explain the causal interaction between consciousness and the physical world. The problem is about explaining how consciousness, which cannot be reduced to physical processes, interacts with the physical world without violating the laws of physics. John Searle claims to have solved the problem of mental causation in his theory of mind, which he calls Biological Naturalism, exhibiting a non-reductionist attitude. In this study, I aim to evaluate Searle's solution to the problem of mental causation. For this purpose, I will first touch on mental causation and how it is understood. Then, I will outline the problem and address the specific criticisms against non-reductionist physicalists. Finally, considering these criticisms, I will show under what conditions Searle's solution to the problem of mental causation can be accepted as correct.
