Technical efficiency and its determinants in watermelon production in Adana Province, Turkey
(Univ Fed Rural Pernambuco, Dept Administracao, 2022) Subasi, Osman Sedat; Uysal, Osman; Kiraci, Mehmet Ali
This study explores the technical efficiency of watermelon farms and their determinants, using the stochastic production frontier function, in the province of Adana in Turkey. The purpose of this analysis was to determine the cost of production and the technical efficiency of watermelon farms. Data of this study were collected from 69 randomly selected watermelon farmers. The results found that the unit production cost of watermelon was $0.10 kg(-1) and that labor costs accounted for the greatest share of the total cost. The findings show that technical efficiency coefficients varied from 0.45 to 1.00 in watermelon farms and the average was 0.82. As for the average farm, the intake of inputs at the same value may be 18% lower. Farm inefficiencies are usually triggered rather than spontaneous by preventable technological causes. There have been findings of farmers expanding their farming size, not only reducing input use but regulating off-farm influences, to enjoy the economy of production. In addition to the government's agriculture insurance programs and policies, their technical efficiencies in the study field should be increased.

THE RELATIONSHIP BETWEEN COVID-19 BURNOUT AND THE MORAL SENSITIVITY OF HEALTHCARE PROFESSIONALS
(Univ Chile, Centro Interdisciplinario Estudios Bioetica, 2023) Yilmaz, Serife; Guven, Gamze Ozbek; Demirci, Mehmet; Karatas, Mehmet
This study aimed to examine the relationship between the burnout of physicians and nurses and their moral sensitivity during the pandemic. This was a descriptive and correlational study. This study was carried out with physicians and nurses who were continuing to work actively during the pandemic. Snowboard sampling method was utilized. The total mean score of the participants on the MSQ was 90.78 +/- 19.10. The total mean score of the COVID-19 Burnout Scale was 34.52 +/- 9.65. A statistically weak and significant correlation was found between the COVID-19 Burnout Scale and the MSQ total score, as well as the benefit and conflict sub-dimensions. It was determined that as MSQ total scores, benefit and conflict scores decreased in healthcare workers, COVID-19 burnout scores increased. In our study, the moral sensitivity of the participants was found to be moderate, and their burnout levels were found to be high. Although there was a weak relationship, it was observed that burnout levels increased as moral sensitivity levels increased. It is crucial that we learn from pandemic experiences and transfer this knowledge to future generations. In particular, we must assimilate these important lessons into training in order to develop and protect the moral sensitivity of healthcare professionals.

This study examines the effects of sports involvement on the well-being of individuals with Down Syndrome who participated in the 2022 Turkish Athletics Championship, as reported by their parents. The championship was organised by the Turkish Special Athletes Sports Federation. Using a qualitative case study design, we thoroughly explore individual experiences, perceptions, and the current situation. Criterion sampling, a method of purposeful sampling, was employed to select participants. The participants were selected using purposive criterion sampling. Information on life changes for the athletes was gathered through semi -structured interviews, which were later transcribed and analysed using content analysis. Five main themes were identified: Physical Development, Social Development, Emotional Development, Psycho -Social Health, and Family Life Satisfaction. The focus was on highlighting the enhancements in family dynamics, shared experiences, and the overall well-being of the family. The study demonstrates that engagement in the championship had a significant impact on the athletes' overall well-being and family satisfaction, underscoring the importance of sports in their lives.

(Verduci Publisher, 2023) Aladag, H.; Kiran, T. R.; Inceoglu, F.; Yildirim, E.; Yaprak, B.; Karabulut, A. B.; Aladag, M.
OBJECTIVE: This study was aimed at comparing the routine laboratory pa-rameters and Galectin-1 levels of control and polycystic ovarian syndrome patients.PATIENTS AND METHODS: 88 patients di-agnosed with polycystic ovary syndrome and 88 healthy controls were considered for the study. Age groups of the patients ranged from 18 to 40. Serum TSH, Beta HCG, glucose, insulin, HO-MA-IR, Hb1A1c, triglyceride, total cholesterol, LDL FSH, LH, E2, prolactin, testosterone, SHBG, DHESO4, HDL, Gal-1 levels were analyzed for each subject.RESULTS: FSH, LH, LH/FSH, E2, prolactin, testosterone, SHBG, DHESO4, HDL and Gal -1 values of the subjects included in the study were statistically significantly different between the groups (p<0.05). Gal-1 and DHESO4 showed a strong positive connection (p=0.05). The sen-sitivity of Gal-1 level in PCOS patients was cal-culated as 0.997 and specificity as 0.716.CONCLUSIONS: High levels of Gal-1 in PCOS patients suggest that it increases due to overex-pression in response to inflammation.

Basal blood concentrations of some orexigenic and anorexigenic hormones in obese and nonobese individuals according to blood groups
(Verduci Publisher, 2022) Karagoz, Z. K.; Aydin, S.; Aksoy, A.; Kalayci, M.; Ugur, K.; Kuloglu, T.; Aydin, S.
OBJECTIVE: Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups. PATIENTS AND METHODS: The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants. RESULTS: When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded. CONCLUSIONS: Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also. these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However. further studies in other ethnic groups are needed to confirm these results.

Mental Training and Anxiety: Examining the Moderating Role of Gender in Athletes
(Univ Illes Balears, 2024) Duyan, Mehdi; Celik, Talip; Karatas, Ozgur; Ilkim, Mehmet; Karatas, Emine Ozturk; Yavuz, Cumaali; Ruzgar, Kerim
This study aimed to examine how gender may influence the relationship between mental training practices and anxiety levels in both individual and team athletes. Using a quantitative approach, data was gathered through convenience sampling using electronically administered questionnaires. A grand total of 348 athletes from secondary school, high school, and university teams in individual and team sports across four Turkish provinces took part in the event. The Mental Training Scale developed by Behnke et al. (2019) was used to evaluate mental training practices, while the Sports Anxiety Scale -2, created by Smith et al. (2006) and Smith, Smoll and Schutz (1990), was used to gauge levels of anxiety. The data analysis included various statistical techniques such as descriptive statistics, Cronbach's alpha for assessing scale reliability, confirmatory factor analysis, correlation analysis to explore variable relationships, and bootstrap regression analysis to investigate the potential moderating effect of gender. The results showed that the predictor variables together explained about 9% of the variation in anxiety (R-2 = .084). There was a noteworthy correlation between mental training practices and anxiety, with mental training practices showing a beneficial impact beta = .30, p < .05). Additionally, gender was found to have a significant influence in a positive direction beta = 1.58, p < .001). In addition, a noteworthy moderating effect was found, suggesting that gender plays a role in the connection between mental training and anxiety beta = -.37, p < .001). It appears that female athletes on school teams are more inclined to incorporate mental training practices into their routines, leading to better anxiety management compared to male athletes who do not engage in such practices.

(Verduci Publisher, 2022) Ekmekyapar, T.; Ekmekyapar, M.; Tasci, I; Sahin, L.; Delen, L. A.
OBJECTIVE: Delirium is an acute disorder in which attention, perception, memory, thought, mood, psychomotor activity and sleep-wake cycles change rapidly. Delirium is also a common clinical syndrome in patients hospitalized in intensive care units due to COVID-19 pneumonia. We reviewed clinical features and predisposing factors of delirium according to psychomotor subtype in patients hospitalized in the intensive care units due to COVID-19 pneumonia. PATIENTS AND METHODS: 64 patients who were hospitalized in the intensive care units due to COVID-19 pneumonia were included. Delirium status and psychomotor subtype were determined by applying the Confusion Assessment Method for the Intensive Care Unit scale to the patients daily. The gender, age, comorbidity, treatments, intubation, and mortality rates of the patients were recorded. Multivariate analyses were performed by examining predisposing factors. arterial blood gases, hemograms, biochemistry, and brain magnetic resonance imaging. RESULTS: There were 64 patients in delirium clinic, 65.6% (n=42) of them were male. Hypokinetic delirium was more common in 60.9% (n=39). 79.4% of the patients who received ventilator support were male (p=0.013). When mortality was analyzed in this group, hypoactive delirium was found to be significantly higher (p=0.035). In addition, leukocyte levels were higher in patients with hypokinetic delirium (p=0.029). Ferritin and fibrinogen levels were higher in patients with hyperkinetic delirium (p=0.039, p=0.008, respectively). CONCLUSIONS: The presence of additional diseases such as advanced age, male gender, hypertension, coronary artery disease, dementia, and hypoxia were factors that increased the frequency of delirium. In addition, the mortality rate was higher in patients with hypokinetic delirium.

Asprosin, visfatin and subfatin as new biomarkers of obesity and metabolic syndrome
(Verduci Publisher, 2022) Ugur, K.; Erman, F.; Turkoglu, S.; Aydin, Y.; Aksoy, A.; Lale, A.; Yalniz, M.
OBJECTIVE: Metabolic syndrome (MetS) and obesity are important public health problems associated with adipose tissue mass. Asprosin, visfatin, and subfatin are new members of which fate in MetS and obesity has not been fully revealed yet. Thus, this study was to investigate the association between asprosin, visfatin, subfatin. and biochemical values, demographic data, and body composition measurement values in MetS patients with and without obesity. PATIENTS AND METHODS: Blood samples were taken from a total of 90 people, including 31 MetS patients with obesity. 29 MetS patients without obesity. and 30 healthy (control). Asprosin, visfatin. and subfatin were studied by the ELISA method. RESULTS: There was a negative correlation between asprosin and Body Mass Index (BMI) in the MetS + Obese group. The correlations between asprosin and urea and fasting insulin (FI) levels in the MetS group were positive and statistically significant (p < 0.05). While there was a statistically significant negative correlation (p < 0.05) between visfatin and BMI in the MetS + Obese group. the correlation with waist circumference in the MetS + Obese and MetS groups was statistically significant and negative (p < 0.05). There was a statistically significant negative relationship (p < 0.05) between aspartate aminotransferase value and visfatin. The results between visfatin values and asprosin and subfatin in all groups were significant (p < 0.05). CONCLUSIONS: There is a direct relationship between circulating amounts of asprosin, visfatin, and subfatin hormones and age, weight, height, diastolic blood pressure, high-density lipoprotein-cholesterol, aspartate aminotransferase. alanine transaminase, and creatinine. Therefore, asprosin, visfatin, and subfatin hormones are the new biomarkers of metabolic turbulence.
Investigation of the effects of quercetin on the structure and properties of zinc-modified hydroxyapatites
(Univ Novi Sad, Fac Technology, 2026) Keser, Serhat; Kaya, Semih; Barzinjy, Azeez A.; Mahmood, Bahroz Kareem; Kareem, Rebaz Obaid; Temuz, Mehmet Mursit; Bulut, Niyazi
In this study, hydroxyapatite (HAp) samples, co-doped with 0.44 at.% of zinc and different amount of quercetin (Zn/Que-HAp), were synthesised using a wet-chemical method and calcined at 900 degrees C. XRD shows HAp as the primary phase with minor beta-TCP. Compared to the Zn-doped sample without quercetin (Q1), quercetin co-doping induces clear structural changes (shifts of lattice parameters a from-0.0017 to +0.0006 nm and c from-0.0026 to-0.0005 nm), accompanied by changes in crystallinity (from-3.6% to +2.5%) and crystallite size (from-3.5 to +0.6 nm), evidencing a distinct co-doping effect. DTA/TGA reveal reduced total mass loss for the Que-containing compositions relative to the Zn-doped sample, indicating enhanced thermal stability of the co-doped lattice. SEM reveals granular morphologies with interconnected porosity, while EDX yields (Ca+Zn)/P ratios greater than 1.67, consistent with Ca-sufficient apatite and modified defect chemistry. DFT calculations resolve the site-specific effects of Zn substitution and predict a preference for perturbation at Ca2 sites. The electronic density of states retains a wide-gap, insulating character, with localised states sensitive to the dopant configuration. By correlating experiment and theory, we demonstrate that the organic-inorganic co-dopant pair offers an effective means to tune lattice metrics, phase balance, and thermal response without compromising the intrinsic insulating nature of HAp.
BIOCHEMICAL EFFECT EVALUATION OF MICROBIAL CHONDROITIN SULPHATE IN EXPERIMENTAL KNEE OSTEOARTHRITIS MODEL
(Parlar Scientific Publications (P S P), 2022) Erenler, Ayse Sebnem; Karabulut, Aysun Bay; Sevimli, Resit; Geckil, Hikmet; Akpolat, Nusret; Unver, Tuba; Otlu, Onder
Osteoarthritis (OA) is the most common chronic joint disease, primarily due to aging. Chondroitin sulfate (CS) is a glycosaminoglycan (GAG) commonly used to treat osteoarthritis. CS can delay the progression of pathology or reverse morphological changes in joint structure. Traditionally CS is produced from animal sources. However, due to different reasons such as contamination, ecological risk, and the possibility of infectious diseases, the trend towards microbial sources has increased because of its advantages such as purer, more antiallergic, and lower Molecular Weight (MW) than animal sources. Biochemical analysis of Microbial CS (MCS), which is a new and significant alternative as a source of CS in the OA healing process, has not been evaluated in the literature yet. This study was designed to analyze the biochemical effects of MCS produced by our team from a microbial source, with an MW value of 269 Daltons, on the osteoarthritis healing process compared to the commercial foiut. We aim to reach data that MCS has a higher antioxidant effect than animal -sourced CS, and in this way, it is a more suitable production for the treatment of osteoarthritis. In this study, knee osteoarthritis was surgically induced in experimental rabbits; and TGF113, CAT, MPO, TOS, and OSI parameters measured in blood samples before the operation and after the healing period were analyzed comparatively. After the surgical application, the rabbits were randomly divided into three groups: control, animal -sourced CS, and E. cull sourced. MCS. The standard rabbit diet was administered daily to 10 rabbits in Group 1 (control), and. CS and MCS were applied daily to the other groups as 17 mg/kg for 12 weeks. Blood samples were taken from rabbits at the 12th week after surgery, and TGF-113, CAT, MPO, TOS, and OSI parameters were biochemically evaluated. This study has confirmed that the antioxidant properties of MCS and data on its effectiveness in controlling oxidative stress compared to animal -sourced CS. Based on these results, it can be concluded that MCS has a significant potency of nutraceutical and therapeutic agents for OA treatment.
Impact of Higher Carbon Dioxide Concentrations and Elevated Temperatures on the Growth of Field Bindweed (Convolvulus arvensis L.) in Turkey
(Tarbiat Modares Univ, 2024) Karaman, Y.; Tursun, N.; Uludag, A.
Field bindweed (Convolvulus arvensis L.) is one of the worst weeds in Turkey as well as worldwide. Climate change, with increasing temperature and concentrations of greenhouse gases and unpredictable extreme weather events, has been among the foremost problems of the world. The effect of climate change on crop husbandry and weeds is to be investigated. The effect of rising temperature and CO2 on different populations of C. arvensis was studied under greenhouse conditions in the Malatya Province of Turkey, in 2019. For this study, the weed seeds were collected from 14 provinces throughout Turkey during 2018. Two temperature regimes (day/night 26/16 degrees C and 29/19 degrees C) and two CO2 levels (400 +/- 50 and 800 +/- 50 ppm) were used. Plant aboveground length, root length, and dry weights of root, aboveground parts, and total plant were not affected by temperature, CO2, and seed source. However, seed source affected root length differently depending on temperature and root length, and root dry weight as affected by CO2 level. In addition, seed source and temperature showed significant effect on measured parameters, while no significant effect was determined for CO2.
THE RELATIONSHIP OF PSYCHOGENIC ERECTILE DYSFUNCTION WITH CORONAVIRUS ANXIETY IN THE COVID-19 PANDEMIC PERIOD
(Carbone Editore, 2021) Ogras, Mehmet Sezai; Yildirim, Kadir
Background/aim: Our aim is to investigate the relationship of psychogenic erectile dysfunction(pED) that develops during the new coronavirus disease(COVID-19) pandemic with coronavirus anxiety using the Coronavirus Anxiety Scale(CAS) and the International Index of Erectile Function-5(IIEF-5) questionnaire. Materials and methods: This study was conducted in Elazig Fethi sekin city hospital during January 2021 to March 2021. Medical history of male patients who were admitted to urology outpatient clinics were taken and physical examinations were performed. Morning serum fasting glucose, total testosterone and prolactine levels were measured. IIEF-5 questionnaire was filled by the patients. Two groups were formed as pED and control group. Both groups filled the CAS questionnaire and the results were compared statistically. Results: IIEF-5 scores were 15.86 +/- 7.53 and 24.26 +/- 0.82 in the pED group and the control group, respectively. The CAS scores were 7.53 +/- 2.02 and 0.40 +/- 0.62 in the pED group and in the control group, respectively. There was a significant difference between these findings. There was a significant negative correlation between IEF-5 scores and CAS scores. (p*=0.00) IIEF-5 scores were significantly lower in the pED group compared to the control group. (p*=0.00) CAS scores were significantly higher in the pED group compared to the control group. (p*=0.00) While there was a statistically significant difference between moderate pED and mild moderate pED in terms of CAS scores (p*=0.02, p*=0.00), there was no statistically significant difference between mild moderate pED and mild pED. (p=0.27). Conclusion: In addition to high contagiousness and mortality rates, COVID-19 causes economic burden and financial losses, leading to negative individual and global psychosocial impact and increased anxiety. Since anxiety is one of the etiological causes of pED, pED encountered during the COVID-19 pandemic is also associated with coronavirus anxiety. Psychiatric support for coronavirus anxiety should be added to pED treatment.
