Topal, Meryem; Gulcin, İlhami
In this study, antidiabetic, anticholinergic, and antioxidant abilities of rosmarinic acid were evaluated and compared to standards. To determine its antioxidant activity different in vitro bioanalytical methods, including total antioxidant activity (TAA), ABTS•+ scavenging activity, O2•- scavenging activity, DPPH· scavenging activity, DMPD•+ scavenging activity, potassium ferric cyanide reduction ability, cupric ion (Cu2+) reduction capacity, H2O2 scavenging activity, and ferrous ions (Fe2+) binding activities were separately performed. Also, butylated hydroxyanisole (BHA), Trolox, α-tocopherol, and butylated hydroxytoluene (BHT) were used as the reference antioxidants. Rosmarinic acid inhibited the linoleic acid emulsion peroxidation by 89.2% while BHA, BHT, Trolox and α-tocopherol inhibited as 87.3, 97.6, 90.3 and 75.3%, respectively, at the same concentration (30 μg/mL). When these results are evaluated, rosmarinic acid had effective TAA than BHA and α-tocopherol and close to BHT and Trolox. In addition, rosmarinic acid exhibited Kİ values of 9.67 ± 0.81 nM towards acetylcholinesterase (AChE) and 33.56 ± 2.96 nM against α-glycosidase enzymes.

Kabakuş Aykut, Memnune; Bilici, Saniye
Purpose: This study was carried out to evaluate the relation between meal patterns and the risk of eating disorders in university students. Methods: The study was conducted on a total of 331 volunteer students with a mean age of 22.08 ± 1.80 years, 56.5% female. Participants’ sociodemographic characteristics, health information and eating habits like meal skipping and dieting were questioned. Sick, Control, One stone, Fat, Food (SCOFF) Eating Disorders Scale and Eating Disorder Examination Questionnaire (EDE-Q) were used to determine eating behavior disorders, with face to face interviews by the researches. Results: A significant correlation was found between dieting and skipping meals and the risk of eating disorders in both genders (p < 0.05). In addition, when the reasons for skipping meals were questioned, a significant relationship was detected between skipping meals and eating behaviour disorders by 3.285 times (p = 0.000). Also, every unit of increase in body mass index (BMI) values of individuals who participated to the study led to an increase in eating disorders by a factor of 1.262 (p = 0.000). Conclusions: Our findings support concerns about the negative health effects of increasing overweight among university students in accordance with the data that the increase in BMI values led to an increase in eating disorders. Notably a significant correlation was found between dieting, skipping meals and the risk of eating disorders in both genders it is highlighting the need for monitoring and early diagnosis of eating disorders in youth with simple scales like SCOFF. Level of evidence: Level V, cross-sectional descriptive study.

The spread of multidrug-resistant Gram-negative (MDR) bacteria is a global public health problem, as infections caused by MDR Gram-negative bacteria are difficult to treat. New antibiotic agents need to be developed to overcome this problem, and phytochemicals show promise at this point. In this study, methanol extracts were prepared from cinnamon, thyme, nettle, white tea, rosehip, and antibacterial activity of the methanol extracts was studied against two MDR Gram-Negative bacteria (K. pneumoniae and A. baumannii) by broth microdilution method. The MICs of methanol extracts of cinnamon, rosehip, thyme, white tea for A. baumannii were found as 0.015125 g/ml, 0.07825 g/ml, 0.030625 g/ml, 0.00796875 g/ml, respectively. It was found that only cinnamon methanol extract had antibacterial activity in the used extract concentrations against K. pneumoniae and the MIC value was 0.0605 g/ml. The effects of plant methanol extract with antibacterial activity and imipenem combinations were studied in vitro using the checkerboard method. The FIC Indexes were obtained from the checkerboard results and it was observed that the combination of methanol extract and imipenem showed an antagonistic or additive/indifferent effect but not a synergistic effect. We evaluated the binding affinity of epigallocatechin 3-gallate, quercetin, cinnamaldehyde, carvacrol, and thymol phytocompounds using in silico methods, which are well known as a phytocompounds in white tea, cinnamon, thyme, nettle, and rosehip and have antibacterial activities. The results suggested that these phytocompounds should be supported with in vivo and in vitro experiments to investigate their potential for being inhibitor candidates.

Demir Doğan, Melike
Quality of life is a multidimensional concept. Therefore, its assessment includes many parameters ranging from happiness and well-being of individuals to environmental quality and ecological structures. A good symptom management is associated with less symptom formation and thus with a better quality of life. Non-pharmacological interventions typically include various psychosocial, behavioral and environmental strategies that can complete traditional treatment to increase the quality of life for cancer patients.

Reis, Hatice Catal; Turk, Veysel; Khoshelham, Kourosh; Kaya, Serhat
Cancer is among the common causes of death around the world. Skin cancer is one of the most lethal types of cancer. Early diagnosis and treatment are vital in skin cancer. In addition to traditional methods, method such as deep learning is frequently used to diagnose and classify the disease. Expert experience plays a major role in diagnosing skin cancer. Therefore, for more reliable results in the diagnosis of skin lesions, deep learning algorithms can help in the correct diagnosis. In this study, we propose InSiNet, a deep learning-based convolutional neural network to detect benign and malignant lesions. The performance of the method is tested on International Skin Imaging Collaboration HAM10000 images (ISIC 2018), ISIC 2019, and ISIC 2020, under the same conditions. The computation time and accuracy comparison analysis was performed between the proposed algorithm and other machine learning techniques (GoogleNet, DenseNet-201, ResNet152V2, EfficientNetB0, RBF-support vector machine, logistic regression, and random forest). The results show that the developed InSiNet architecture outperforms the other methods achieving an accuracy of 94.59%, 91.89%, and 90.54% in ISIC 2018, 2019, and 2020 datasets, respectively. Since the deep learning algorithms eliminate the human factor during diagnosis, they can give reliable results in addition to traditional methods.

Reis, Hatice Catal; Turk, Veysel
COVID-19 (SARS-CoV-2), which causes acute respiratory syndrome, is a contagious and deadly disease that has devastating effects on society and human life. COVID-19 can cause serious complications, especially in patients with pre-existing chronic health problems such as diabetes, hypertension, lung cancer, weakened immune systems, and the elderly. The most critical step in the fight against COVID-19 is the rapid diagnosis of infected patients. Computed Tomography (CT), chest X-ray (CXR), and RT-PCR diagnostic kits are frequently used to diagnose the disease. However, due to difficulties such as the inadequacy of RT-PCR test kits and false negative (FN) results in the early stages of the disease, the time-consuming examination of medical images obtained from CT and CXR imaging techniques by specialists/doctors, and the increasing workload on specialists, it is challenging to detect COVID-19. Therefore, researchers have suggested searching for new methods in COVID- 19 detection. In analysis studies with CT and CXR radiography images, it was determined that COVID-19-infected patients experienced abnormalities related to COVID-19. The anomalies observed here are the primary motivation for artificial intelligence researchers to develop COVID-19 detection applications with deep convolutional neural networks. Here, convolutional neural network-based deep learning algorithms from artificial intelligence technologies with high discrimination capabilities can be considered as an alternative approach in the disease detection process. This study proposes a deep convolutional neural network, COVID-DSNet, to diagnose typical pneumonia (bacterial, viral) and COVID-19 diseases from CT, CXR, hybrid CT + CXR images. In the multi-classification study with the CT dataset, 97.60 % accuracy and 97.60 % sensitivity values were obtained from the COVID-DSNet model, and 100 %, 96.30 %, and 96.58 % sensitivity values were obtained in the detection of typical, common pneumonia and COVID-19, respectively. The proposed model is an economical, practical deep learning network that data scientists can benefit from and develop. Although it is not a definitive solution in disease diagnosis, it may help experts as it produces successful results in detecting pneumonia and COVID-19.

Machine learning has been actively used in disease detection and segmentation in recent years. For the last few years, the world has been coping with the Coronavirus disease 2019 (COVID-19) pandemic. Chest-computerized tomography (CT) is often a meaningful way to detect and detect patients with possible COVID-19. This study aims to classify COVID-19 and non-COVID-19 chest-CT images using deep learning (DL) algorithms and investigate whether we can achieve successful results in different parameters using four architectures. The study was performed on proved positive COVID-19 CT images, and the datasets were obtained from the GitHub public platform. The study evaluated four different deep learning architectures of VGG16, VGG19, LeNet-5, and MobileNet. The performance evaluations were used with ROC curve, recall, accuracy, F1-score, precision, and Root Mean Square Error (RMSE). MobileNet model showed the best result ; F1 score of 95%, the accuracy of 95%, the precision of 100%, recall of 90%, AUC of 95%, and RMSE of 0.23. On the other hand, VGG 19 model gave the lowest performance; F1 score of 90%, the accuracy of 89%, the precision of 90%, recall of 90%, AUC of 89%, and RMSE of 0.32. When the algorithms' performances were compared, the highest accuracy was obtained from MobileNet, LeNet-5, VGG16, and VGG19, respectively. This study has proven the usefulness of deep learning models to detect COVID-19 in chest-CT images based on the proposed model framework. Therefore, it can contribute to the literature in Medical and Engineering in COVID-19 detection research.

Background Mechanical bowel obstruction (MBO) is one of the principal pathologies requiring emergency surgery and a significant worldwide cause of morbidity. The identification of patients in whom bowel obstruction resolves spontaneously is important in terms of preventing unnecessary surgical interventions and future potential adhesions. The decision-making process is difficult in patients presenting without classic examination findings. Methods 36 female Sprague-Dawley rats randomly divided into six experimental groups. In Group 1, 3 and 5, laparotomy was performed, with blood and tissue specimens being collected after 1, 2 and 6 h, respectively. In Group 2, 4 and 6, the ileum segment was ligated following laparotomy, and blood and tissue specimens were collected after 1, 2 and 6 h, respectively. The ileum specimens were examined macroscopically, after which 1-cm sections were taken and examined in terms of histopathological changes. IMA and SCUBE-1 levels were determined for each group, and macro- and microscopic tissue examination findings were compared between the groups. Results Comparison within the groups exposed to waiting times of 1 h (groups 1 and 2), 2 h (groups 3 and 4) and 6 h (groups 5 and 6) revealed higher mean IMA and SCUBE-1 levels in rats undergoing ligation together with incision (groups 2, 4, and 6) compared to those undergoing laparotomy only (groups 1, 3, and 5). Correlation analysis was applied to determine the relationship between total scores obtained from histopathological examination and IMA and SCUBE-1 values. The analysis revealed strong, significant and positive correlation between histopathological examination scores and IMA (r=0.643, p=0.000) and SCUBE-1 (r=0.509, p=0.002) values. Conclusion The study findings showed that both IMA and SCUBE-1 values increased in a strangulated MBO model in rats. We think that IMA and SCUBE-1 values can be used as a markers of damage in the early period in strangulated MBO, and that the patient's surgery requirement can thus be determined in the early period.

Purpose: Visual feedback and music while warm up may help elicit peak performance, but its effect during the Wingate anaerobic test (WAnT) in futsal players is unexplored. Therefore, the aim of this study was to examine the effects of music and visual stimulus on WAnT performance in futsal players. Methods: The study included 17 young male futsal players (age, 21.53 +/- 1.32 years; height, 177.59 +/- 5.75 cm; 73.71 +/- 9.31 kg; BMI 23.342 +/- .47). The WAnT was administered using three distinct protocols: with music (M), without music (NM), and with music and visual feedback (MV) following a 10-min warm-up at 72-h intervals. After WAnT, the following parameters were evaluated: (a) peak power output: PPO (W), (b) relative peak power output: RPPO (W/kg), (c) mean power output: MPO (W), (d) relative mean power output: RMPO (W/kg), (e) fatigue index: FI (%), and (f) minimum power output MIPO (W). Results: MV indicated that futsal players' WAnT values, including PPO, RPPO, MPO, RMPO, and MIPO improved more than with other protocols (p < 0.05). However, there was no significant difference between protocols for FI (%) WAnT values (p > 0.05). Conclusions: Listening to music and watching visual feedback while warm up before performing WAnT performance suggest to coaches and futsal players.

Performance is judged using a variety of methods to ensure uniformity between competitions. Uchikomi Fitness Test (UFT) could accomplished between morning qualifying and evening finals. The purpose of this study is to investigate the impact of different warm-up protocols on UFT at different times of the day in female judokas. Ten volunteer women who had been practising judo on a regular basis for more than 5 years and actively competed in international tournaments took part in this study. Judokas completed UFT, either after no-warm-up (NWU), specific warm-up (SWU), and linear+lateral warm-up (FWU) protocols for two times a day in the morning: 09:00-11:00 and in the evening: 16:00-18:00, on non-consecutive days. In conclusion, there was a significant increase in UFT scores (F = 9.89; p = 0.002), a + b (F = 4.42; p = 0.04) and heart rate (F = 28.99; p < 0.001) in the early evening compared to the morning. Increases in UFT performance were observed in the SWU protocol compared to the NWU and FWU protocols (p < 0.05). However, the interaction between time of day and warm protocol was not significant (p > 0.05). The UFT performance revealed diurnal variation, and the judokas' performances may be favourably affected more in the late hours, particularly following SWU procedures.

Healthcare workers (HCWs) providing medical support while facing one of the highest levels of adverse and potentially fatal outcomes due to COVID-19 are put in a vulnerable position leading to the development of mental health problems. The development of any prevention and intervention programs to reduce this risk is possible with better understanding and knowledge of possible vulnerability factors. The aim of the present study is to investigate psychological effect of working directly with patients infected with COVID-19 (WD) and possible individual vulnerability factors for the development of psychological problems in HCWs. The data used in this cross-sectional study were collected using online self-reported questionnaires from 290 HCWs aged 21-61 years old. The mean score of the scales of 145 HCWs-WD and 145 HCWs not WD (HCWs-NWD) were compared by independent sample t test. Associations between childhood traumas, metacognitive dysfunctional beliefs and internalizing symptoms were analyzed using structural equation modelling (SEM). The depression, anxiety, stress symptoms levels, somatization and sleep problem levels were found to be higher in HCWs-WD compared to HCWs-NWD. SEM revealed that childhood trauma levels was associated with the increased risk of internalizing problems, and metacognitive dysfunctional beliefs had a partial mediator role between childhood traumas and internalizing symptoms in HCWs-WD. Improving metacognitive abilities may hence need to be considered in prevention programs for the HCWs. The findings can also be used to set up further research on the specific interventions on the HCWs who are at a risk as their profession entails them being in such traumatic situations.

Background and purpose: Pain experiences in childhood are very likely to be reflected in adulthood. The early evaluation of the concept of pain in children may eventually lead to.better patient outcomes in the future. Therefore, we aimed to culturally and developmentally adapt the Concept of Pain Inventory for Children (COPI) for Turkish children.Methods: This descriptive, correlational study was conducted with 239 post-operative children aged 8-12 years between June and December 2021. The research adhered to COSMIN guidelines. The data were collected using a descriptive information form and the COPI. Factor analysis, Cronbach's alpha, and item-total score analysis were used for the data analysis.Results: The resulting unidimensional scale consists of 12 items in Turkish. The scale explained 65% of the total variance. The exploratory factor analysis showed that the factor loadings of items ranged from 0.64 to 0.91. The confirmatory factor analysis showed that the factor loadings of items ranged from 0.66 to 0.92. Goodness of fit indexes were found to be as follows: Normed Fit Index >0.90; Incremental Fit Index >0.90; Comparative Fit Index >0.90; and the Root Mean Square Error of Approximation <0.08. The total Cronbach's alpha coefficient of the scale was 0.78 (reliable). Conclusions: The 12-item Turkish translation of the COPI was deemed valid and reliable in 8-12-year-old children in a post-operative setting. Practice implications: Evaluation of children's pain concepts during childhood may contribute to the identification of conceptual gaps for pain science education.(c) 2022 Elsevier Inc.

2019 yılı sonunda Çin’de ortaya çıkan COVID-19 Pandemisi, 2020 yılının ilk aylarından itibaren Dünya genelinde birçok alanda kısıtlamalara ve düzen değişikliklerine neden olmuştur. Diğer tüm alanlarda olduğu gibi ulaştırma hizmetleri ve ulaşım karakteristiklerinde de bu pandemi nedeniyle büyük değişiklikler görülmüştür. Ülkemizde pandeminin görülmeye başlandığı tarihten itibaren pandeminin seyrine ve virüse yakalanan vatandaş sayısındaki artışa bağlı olarak bazı dönemlerde sokağa çıkma kısıtlamaları getirilmiştir. Bu kısıtlamalara bağlı olarak toplu taşıma sefer sıklıkları, şehir içi ve şehirlerarası toplu taşıma hizmetlerini kullanan yolcu sayıları, trafikteki araç sayısı vb. ulaşım ile ilgili birçok alanda değişiklikler görülmeye başlanmıştır. Bu çalışma kapsamında, pilot kent olarak seçilen Antalya şehir merkezinde yer alan ana arterler üzerinde pandemi etkisi nedeniyle trafikteki araç sayısında meydana gelen değişimler incelenmiştir. Elde edilen sonuçlar detaylı olarak irdelendiğinde, pandemi sırasında kısıtlama günlerinde araç sayısında önemli derecede azalmalar görülmüştür. Yine elde edilen sonuçlara göre, ülkemizde trafiğe çıkan araç sayısında artış meydana gelmesine rağmen, kısıtlama günleri dışındaki günlerde trafikteki araç sayısının pandemi öncesindeki sayıya yakın olduğu görülmüştür. Bu sonuç, pandemi nedeniyle sürücülerin toplu taşıma yerine bireysel araç kullanımına yöneldiklerini doğrulamaktadır.

Yatırım, harcama, tasarruf gibi finansal davranışlarda atılan her birdoğru finansal adım, birey adına sağlıklı bir gelecek anlamına gelmektedir. Bireyin finansal sağlığı üzerinde etkili olan faktörleri,finansal sosyalizasyon, finansal eğitim, kredi kartı kullanımı, finansal stres ve endişe olarak dört gruba ayırmak mümkündür.Finansal sosyalizasyonu aile ile kredi kartı kullanımını finansal piyasalar ve ihtiyaçlar ile finansal eğitimi eğitim kurumlarımız ileilişkilendirmek mümkündür. Her bir faktörün, var olup-olmaması, yeterli-yetersiz oluşu, bireyin finansal öz yeterliliğini olumluya da olumsuz etkilemektedir. Çalışmada, bu faktörlerin, bireyin finansal öz yeterliliği üzerinde olan etkileri belirlenerek,ailelerde özellikle de ebeveynler üzerinde, finansal piyasalarda özellikle bankacılık alanında, eğitim kurumlarında, bu alanayönelik farkındalığın artırılması amaçlanmıştır.Araştırmada, bireyin finansal öz yeterliliği üzerinde etkili olan, yukarıda ifade edilen değişkenler kullanılarak bir modeloluşturulmuştur. Modelin değerlendirilebilmesi ve değişkenler arasındaki ilişkilerin belirlenmesi amacıyla, GümüşhaneÜniversitesi’nde eğitim alan 323 öğrenciye anket uygulanarak veriler elde edilmiştir. Verilerin analiz edilmesinde faktör,korelasyon ve regresyon analiz yöntemleri kullanılmıştır. Regresyon analizi sonuçlarına göre bireylerin finansal öz yeterlilikleriüzerinde en fazla olumlu etkiye sahip olan bağımsız değişken finansal bilgi ve eğitim değişkenidir. Yapılan değerlendirmelerde,öğrencilerin finansal öz yeterlik seviyeleri üzerinde, finansal sosyalizasyon, finansal bilgi ve eğitim, finansal stres ve endişe,borçlanma durumlarının etkili olduğu tespit edilmiştir.

Diker, Ersin; Çelik, Fatih
The novel Coronavirus (Covid-19), emerging in Wuhan, China, in December 2019, has rapidly spread to many parts of the world, causing thousands of people to die. In addition to its physical and biological effects, the virus has some psychological effects. Psychological disorders, such as depression, stress, and anxiety are some of these effects. In this process, people have started to use social media platforms to meet their information and social support needs more often. The current study aimed to analyze the mediator role of fear of missing out (FoMO) in the relationship between people's depression and stress level with compulsive social media use (CSMU) in Covid-19 process through a structural equation model (SEM). To this end, an online survey was conducted between 14-20 June 2020 in Turkey (N = 871, 60.7 % women, Mage = 28.70, SD = 9.99) and convenience sampling method used. The findings showed that while depression positively correlates with CSMU, there was no relationship between stress and CSMU. In addition, there was a positive relationship between depression and stress with FoMO, FoMO with CSMU, as well. Moreover, FoMO had a mediation role in the relationship between depression and stress with CSMU. The research’s findings are expected to contribute to the effective communication of the official institutions that manage the crisis related to Covid-19 with the public through social media.

Arslan, Mesut; Atalay, Emre Serdar; Taşkaya, Cengiz
The aim of this study was to investigate the effects of diaphragmatic kinesiology taping on physical fitness parameters in university students. Twenty male university students participated in this study voluntarily. Muscle facilitation technique was applied on back and abdominal region coinciding diaphragm muscle. For sham application, same tape material was applied without a special stretch or technique. International Physical Activity Questionnaire Short Form (IPAQ-SF), 2 km walking test, prone plank, side plank, Sorenson test and Standing stork test were used for evaluation. After the first evaluation, we waited 72 hours for the second application. Firstly, 10 participants had tape application and the other half had sham taping. In the second session, we changed the application. In the taping and placebo applications, a significant relationship was found between prone endurance test values before and after application (p<0.05). In the kinesio tape and placebo applications, a significant relationship was found in 2 km walk performance compared to untaped condition evaluation before and after the application (p <0.05). In the before-after evaluations within the group, a significant difference was found in the kinesio tape and placebo applications in the 2-kilometer walking test, but there was no statistically significant difference in the comparisons between the kinesio tape and placebo applications.
