Effect of electromagnetic field on whole blood, biochemical and hormone level in human

The electromagnetic field is increasing in our environment and these exposures cause concern. The aim of our study is to investigate the effects of magnetic fields generated by the hairdryer devices used by women working in the same job on their serum biochemistry, whole blood, and hormone values. The sixteen women working continuously in hairdressing salons were included in the study. Two groups of studies were designed: control (n:8, mean age: 22.25±6.04) and experimental group (n:8, mean age:23,62±6.67). The biochemical (median values of alanine aminotransferase, aspartate aminotransferase, triglycerides, and very-low-density lipoprotein were found high) and hormonal results of the experimental group were compared with the biochemical (cholesterol, low-density lipoprotein, and very high-density lipoprotein had high median values) and hormonal results of the control group and no significant difference was found (p>0.05). When the whole blood parameters were examined, the white blood cells and mean platelet volume results of the experimental group were significant (p<0.05), while there was a meaningless difference between red blood cell, hemoglobin, hematocrit, mean corpuscular volume, red cell distribution width and platelet values (p>0.05). It is evident from the results that occupational exposure to magnetic fields constantly leads to changes in the biochemistry, hormone and whole blood parameters of the female

Spiritual Well-Being, Social Support, and Financial Distress in Determining Depression: The Mediating Role of Impact of Event During COVID-19 Pandemic in Iran

This study investigates the relationship between spiritual well-being, social support, and financial distress with depressive symptoms due to the COVID-19 pandemic. A path analysis was used to analyze data collected from 1,156 Iranian participants via an online survey. The results showed that spiritual well-being and social support were negatively related to depressive symptoms and financial distress. The impact of COVID-19 events showed negative associations with depressive symptoms. In addition, the link between spiritual well-being and financial distress with depressive symptoms was partially mediated by the impact of events.

Student satisfaction and academic efficacy during online learning with the mediating effect of student engagement: A multicountry study

The COVID-19 pandemic caused unprecedented changes to educational institutions, forcing their closure and a subsequent shift to online education to cater to student learning requirements. However, successful online learning depends on several factors and may also vary between countries. As such, this cross-sectional study sought to investigate how engagement of university students, a major driver of online learning, was influenced by course content, online interaction, student acceptance, and satisfaction with online learning, as well as self-efficacy across nine countries (China, India, Iran, Italy, Malaysia, Portugal, Serbia, Turkey, and the United Arab Emirates) during the COVID-19 pandemic. Using a questionnaire-based approach, data collected from 6,489 university students showed that student engagement was strongly linked to perception of the quality of the course content and online interactions (p < .001). The current study also indicated that online interactions are a major determinant of academic efficacy but only if mediated by engagement within the online learning context. A negative correlation between student engagement and satisfaction with online learning was found, demonstrating the importance of students being engaged behaviorally, emotionally, and cognitively to feel satisfied with learning. Academic efficacy and student satisfaction were explained by course content, online interaction, and online learning acceptance, being mediated by student engagement. Student satisfaction and, to a lesser degree academic efficacy, were also associated with online learning acceptance. Overall, the structural equation model was a good fit for the data collected from all nine countries (CFI = .947, TLI = .943; RMSEA = .068; SRMR = .048), despite differences in the percentage variations explained by each factor (no invariance), likely due to differences in levels of technology use, learning management systems, and the preparedness of teachers to migrate to full online instruction. Despite limitations, the results of this study highlight the most important factors affecting online learning, providing insight into potential approaches for improving student experiences in online learning environments. © 2023 Sharif Nia et al.

Perakende gıdalardan izole edilen farklı Aeromonas hydrophila suşlarının protein profilleri

Bu çalışmada Türkiye’de çeşitli gıdalardan izole edilen lokal 20 Aeromonas hydrophila ve bir referans suşun (ATCC 7966) toplam hücre proteinleri SDS-PAGE (sodyum dodesilsülfat poliakrilamid jel elektroforezis) ile analiz edildi. Suşlar içinde değişkenlik gözlendi. Proteinlerin moleküler ağırlıkları 21-116 kDa arasında olduğu bulundu. A. hydrophila’nın hem referans hem de lokal suşlarında 37.8 den 101.4 kDa kadar protein polipeptid bantlarının yaygın olduğu görüldü. Bu çalışma A. hydrophila ve referans suş (ATCC 7966) arasında genetik bir benzerlik olduğunu göstermektedir. Bu protein patternleri epidemiyolojik çalışmalarda suş ayırımını kolaylaştırmada yararlı olabilir.In this study, whole cell protein profiles of 20 local strains of Aeromonas hydrophila isolated from different foods in Turkey and one reference strain (ATCC 7966) were analyzed by SDS-PAGE (sodium dodecylsulfate polyacrylamide gel electrophoresis). It was observed that there was variability among the strains. Molecular weight of proteins were found to be between 21-116 kDa. The protein polypeptide bands from 37.8 to 101.4 kDa were common in both local strains and reference strain of A. hydrophila. The results of this study indicated that there is a genetic similarity between strains of A. hydrophila and reference strain (ATCC 7966). These protein patterns are likely to be beneficial to differentiate between the strains in epidemiological studies

Revisiting weighted-rankit method by a hypothetical data set

Bitki gen kaynaklarının morfolojik karekterizasyonu ve değişik bölgeler için çeşit adaptasyonları Türkiye’deki bahçe bitkileri araştırmalarının önemli bir kısmını oluşturmaktadır. Her iki alan da değişik önem seviyelerinde birçok bahçe bitkileri özelliğinin çok sayıda genotip için değerlendirmesini gerektirmektedir. Bu tip denemelerde sıklıkla tartılı derecelendirme yöntemi bir istatistiksel yöntem olarak kullanılmaktadır. Tartılı derecelendirme ile ilgili yapılan kaynak taramasında, halen uygulanmakta olan yöntemin bahçe bitkileri araştırmaları için ilk olarak önerilen yöntemden önemli ölçüde farklı olduğu görülmüştür. Bu çalışmada, yapay bir veri dosyası kullanarak, orijinal yöntemle Türkiye’deki çalışmalarda kullanılan tartılı derecelendirme yönteminin aynı veri seti için değişik sonuçlar verebileceğini gösterdik. Önem testi içermeyen mevcut yöntem, test edilen genotiplerin toplam puanları arasında, istatistiksel olarak önemli olup olmadığı belirlenememektedir. Ancak bu yöntemdeki hiçbir sonuç istatistiksel olarak desteklenmemektedir. Bu yüzden bahçe bitkilerindeki çok-değişken içeren araştırmalarda ya “asıl” tartılı derecelendirme yönteminin titizlikle takip edilmesini ya da diğer çok-değişkenli analiz yöntemlerinin kullanılmasını önerilmektedir.Morphological characterization of plant genetic resources and variety trials in various ecological regions are important parts of horticultural research in Turkey. Both topics require evaluation of many horticultural traits with different weights for a large number of genotypes. Weighted-rankit (WR) method is a tool commonly used in statistical analyses of these experiments. Our survey on the WR indicated that the common interpretation of the method significantly deviates from the original method suggested for horticultural research in the literature. In this study, using a hypothetical data set, we demonstrated that interpretations as made in both Turkish and original horticultural research may suggest different conclusions for the same data set. Not having a significance test, the current version of interpretations commonly found in horticultural studies in Turkey may be erroneous as it recovers variability among the total scores of the entities tested without considerations of whether or not those are statistically different. However, in this method, conclusions would not be supported by a valid statistical test. Therefore, we suggest either strictly following the &amp;#8220;original&amp;#8221; WR method or using other valid multivariate methods for analyzing multi-traits studies in horticultural research

Maternal behaviour of Awassi sheep and behaviour of the lambs during the first hour after parturition

Data from sixty-one 2–5-year-old Awassi ewes (38 single and 23 twin births) were evaluated in order to determine behaviour at parturition and the following first hour. Observations were subjected to Kolmogorov–Smirnov and Shapiro–Wilk tests, Pearson’s chi-square test, independent samples t-test, and ANOVA. The Awassi sheep exhibited sniffing action after parturition as the initial behaviour, choosing the back part of the lamb. First licking and sniffing times were found to decrease with maternal age; calculated average data for these characteristics were 138.3 &plusmn; 15.39 and 118.3 &plusmn; 26.48 s for singlets, and 147.7 &plusmn; 15.12 and 123.6 &plusmn; 29.54 s for twins, respectively (P &lt; 0.05). Total mean licking time was found to be 27.9 &plusmn; 0.81 min in single births and 26.2 &plusmn; 0.90 min in twin births. The mean first successful standing-up time was determined to be 23.2 &plusmn; 1.83 min in single births, 21.1 &plusmn; 1.63 min in the firstborn twin, and 20.2 &plusmn; 2.96 min in the second-born twin (P &lt; 0.05). In the same order, the average suckling time of lambs was specified as 34.3 &plusmn; 2.27 min, 34.3 &plusmn; 2.50 min, and 29.2 &plusmn; 3.70 min (P &lt; 0.05), respectively. In conclusion, Awassi ewes showed good maternal behaviour and encouraged their lambs in standing up and suckling.Data from sixty-one 2–5-year-old Awassi ewes (38 single and 23 twin births) were evaluated in order to determine behaviour at parturition and the following first hour.

Comparative assessments of multivariate nonlinear fuzzy regression techniques for egg production curve

The modelling process of egg production curves, where environmental and genetic factors are highly effective, is quite complex and difficult. In particular, the limitations of measurement and the errors encountered during the measurement process may cause uncertainty in the egg production process. In this study, multivariate nonlinear fuzzy regression analysis was used by configuring neural networks and least squares support vector machines in order to express the uncertainty in the system structure during the egg production process. This method was used to obtain the predicted values for egg production in the fuzzy frame. In the study, two different data sets were used which were measured for egg performance and egg weight variables in daily and weekly time periods. Multivariate nonlinear fuzzy regression analysis results were compared with both the observed values and the multivariate classical regression analysis results. Results of analysis show that multivariate nonlinear fuzzy regression analysis with neural networks is more successful than other methods and can be used as an alternative to classical methods in poultry farming

The evaluation of the prevalence of disease among the cats and dogs admitted to clinics of Veterinary Faculty, Mustafa Kemal University (2003-2006)

Bu çalışmada 1 Ocak 2003-31 Aralık 2006 tarihleri arasında Mustafa Kemal Üniversitesi Veteriner Fakültesi Kliniklerine getirilen kedi ve köpeklerin değerlendirilmesi amaçlandı. Bu tarihler arasında 76 kedi ve 366 köpek muayene edildi. Bu hayvanlar tür, cinsiyet, mevsim, anabilim dalı ve hastalıklara göre değerlendirildi. Hayvanların hastalanmalarının mevsimlere bağlı olduğu (p<0.01) ve hastalıkların yaygın olarak ilkbahar ve yaz aylarında ortaya çıktığı gözlendi. Kedi ve köpeklerin Anabilim Dallarına göre dağılımları incelendiğinde; hastaların en fazla İç Hastalıkları Anabilim Dalı (n=202, %46), daha sonra Cerrahi Anabilim Dalı (n=192, % 43) ve en az da (n=48, %11) Doğum ve Jinekoloji Anabilim Dalı hastalıkları olduğu görülmüştür. Hasta kedi ve köpeklerin daha çok 0-12 aylık yaşlarda oldukları saptandı. Kliniklere getirilen köpeklerin önemli bir kısmını (n=224, %61) erkek hayvanlar oluşturmasına karşın, kedilerin önemli bir kısmını (n=49, %64) dişi hayvanlar oluşturdu. Hastalarda en fazla sindirim sistemi hastalıkları gözlenirken, bunları solunum sistemi hastalıkları, travma, topallık ve kırık olguları gibi ortopedik bozukluklar takip etmiştir. Sonuç olarak, bu çalışmada kedi ve köpeklerde gözlenen hastalıkların değerlendirilmesi, hayvan sahiplerinin bu bölgede görülen kedi ve köpek hastalıkları hakkında bilinçlendirilmesine yardımcı olacağı düşünülmektedir.The aim of this study was to evaluate the prevalence of the disease among the dogs and cats admitted to the clinic of Mustafa Kemal University Faculty of Veterinary Medicine between 1st January 2003 and 31st December 2006. Clinical examination of the 76 cats and 366 dogs were performed. These animals were evaluated in breed, sex, seasons, clinical departments, and the diseases. It was observed that the disease in cats and dogs occurred due to seasonal effects (p&lt;0.01), and the diseases in dogs and cats commonly observed in spring and summer seasons. When the distributions of the patients admitted to Departments in Veterinary Faculty Clinics was evaluated, the patients were commonly brought to Department of Internal Medicine (n=202,46%), these were followed by Department of Surgery (n=192, 43%) and Department of Gynecology and Reproduction (n=48, 11%). Diseases were most commonly detected between 0-12 months aged in cats and dogs. Although the dogs admitted to Veterinary Faculty Clinics were male (n=224, %61), female cats (n=49, 64%) mostly brought to all the departments. Digestive system diseases were most commonly observed in cats and dogs, and these were followed by respiratory and orthopedic disturbances such as trauma, fracture and lameness. In conclusion, it was thought that the evaluation of the diseases observed in cats and dogs in this study will help to make the owners conscious of cats and dogs diseases in this region
