Effects of Individual and Institutional Factors for Sustainable Chains and Production
No full textAmaç: Bu çalışma, gelişmekte olan pazarlar üzerinde odaklanarak, kurumsal baskılar ve bireysel uyum performansının yeşil tedarik zinciri uygulamaları ve tersine lojistiğin benimsenmesi üzerindeki etkilerini ve bunların üretime dayalı CO2 emisyonları üzerindeki etkilerini Türkiye örneği üzerinden ayrıntılı olarak incelemeyi amaçlamaktadır. Yöntem: Araştırma yönteminde verilerin analizi için yapısal eşitlik modellemesi (SEM) ve SmartPLS kullanmıştır. Bu yaklaşım, kurumsal baskılar, bireysel uyum performansı, yeşil tedarik zinciri uygulamaları, tersine lojistik ve CO2 emisyonları arasındaki ilişkilerin derinlemesine incelenmesine olanak sağlamıştır. Bulgular: Kurumsal baskıların tersine lojistiği doğrudan etkilediği, ancak yeşil tedarik zinciri uygulamaları veya CO2 emisyonlarının azaltılması üzerinde minimum doğrudan etki gösterdiği nüanslı bir ilişki, bulgularla ortaya koyulmaktadır. Buna karşılık, bireysel adaptif performansın hem yeşil tedarik zinciri uygulamalarını hem de tersine lojistiği geliştirmede çok önemli olduğu bulunmuştur. Özellikle, tersine lojistiğin CO2 emisyonlarının azaltılmasında önemli ölçüde etkili olduğu vurgulanmaktadır. Özgünlük: Bu çalışma, kurumsal baskıların ve bireysel uyum performansının gelişmekte olan pazarlarda yeşil tedarik zinciri yönetimini nasıl etkilediğini ortaya koyarak ve özellikle Türkiye örneği üzerinden alan içi değişkenliğin üstün uygulamaların benimsenmesi üzerindeki etkisinin bireysel uyum performansına bağlı olduğunu göstererek literatürü zenginleştirmektedir.Purpose: This study aims to examine the impacts of institutional pressures and individual adaptation performance on the adoption of green supply chain practices and reverse logistics, and their effects on production-based CO2 emissions, focusing on emerging markets with a detailed case study of Türkiye. Methodology: The research methodology employed structural equation modeling (SEM) and SmartPLS for the analysis of the data. This approach allowed for an in-depth examination of the relationships between institutional pressures, individual adaptive performance, green supply chain practices, reverse logistics, and CO2 emissions. Findings: The findings reveal a nuanced relationship where institutional pressures directly impact reverse logistics but show minimal direct influence on green supply chain practices or CO2 emissions reduction. In contrast, individual adaptive performance is crucial in enhancing both green supply chain practices and reverse logistics. Notably, reverse logistics is significantly effective in reducing CO2 emissions. Originality: This study enriches the literature by revealing how institutional pressures and individual adaptive performance influence green supply chain management in emerging markets, particularly demonstrating through the case of Türkiye that the impact of within-field variability on the adoption of superior practices depends on individual adaptive performance
Evidence-based nursing practices in umbilical cord care
No full textApproximately 2.5 million neonatal deaths occur every year in the world, most of them in low-and middle-income countries (Rosa Mangeret et al., 2022). Umbilical cord infections are among the main causes of these deaths. The umbilical cord, which is cut after the birth of a newborn, is an entry point for bacteria. Bacteria can rapidly colonize the moist cord and reach the bloodstream, causing sepsis and death (Aku et al., 2023; Sener Taplak and Bayat, 2016). The umbilical cord care applied to newborns prevents bacterial colonization and accelerates the natural separation time of the cord. The umbilical cord care applied to newborns aims to prevent bacterial colonization and accelerate the natural cord separation time (Shen et al., 2023). Neonatal deaths can be significantly reduced with the prevention of sepsis by providing appropriate, effective, and safe umbilical care. Against this, the best umbilical care in the postpartum period is still controversial (Quattrin et al., 2016; Abbaszadeh et al., 2016). The World Health Organization (WHO) recommends dry umbilical cord care in countries where obstetric care is adequate and neonatal mortality rates are low. However, in cases where infection rates are high and poor hygienic conditions exist, they recommend the use of topical antiseptics (World Health Organization, 2013; World Health Organization, 2017). Despite these recommendations, umbilical cord care practices are still affected by unreliable traditional practices and inequalities in healthcare. The effectiveness and safety of umbilical care should be investigated to ensure the best results during this period, which is critical for babies' lives (Reis et al., 2020). Evidence-based umbilical cord care practices such as topical human milk application, and application of antiseptic solutions such as chlorhexidine, 70% alcohol, triple dye, povidone iodide, and arnica montana extracts are of great importance in reducing morbidity and mortality due to sepsis. In this section, evidence-based interventions in umbilical cord care for newborns will be discussed in light of literature information. © 2025 by Nova Science Publishers, Inc. All rights reserved
The effect of body composition and lifestyle habits on functional movement capacity in inactive overweight adults males
Full text linkBackground: This study investigated the effects of body composition and lifestyle habits on functional movement capacity in inactive overweight men. Methods: A crosssectional study was conducted with 112 men (age = 30 +/- 11 years; BMI = 25.82 +/- 4.79 kg/m2). Participants completed a lifestyle habits questionnaire. Anthropometric measurements, including height, weight, muscle mass, and body fat percentage, were recorded. Functional Movement Screen (FMS) tests assessed functional movement capacity. Stepwise multiple linear regression analyzed the predictors of FMS scores, and lifestyle habits were compared. Results: Body fat percentage accounted for 24% of the variance in FMS scores (F(1-110) = 21.378, p < 0.001), with a coefficient of -0.159, indicating a negative association. Participants without chronic diseases had significantly higher FMS scores compared to those with chronic diseases (% change = 12.14; p = 0.037). Other lifestyle habit parameters showed no significant differences. Conclusions: Higher body fat percentages negatively influence functional movement capacity. Participants without chronic diseases exhibited better functional movement scores, emphasizing the positive role of general health on movement quality. Strategies focusing on reducing body fat and improving overall health may enhance functional movement capacity in this population.Princess Nourah bint Abdulrahman University, Riyadh, Saudi Arabia [PNURSP2025R 286]This research was funded by Princess Nourah bint Abdulrahman University Researchers Supporting Project number (PNURSP2025R 286) , Riyadh, Saudi Arabia.

Investigation of anatomical variations in the superficial cerebral venous system and its anastomoses through magnetic resonance venography
Full text linkDural venöz sinüsler ve yüzeyel kortikal anastomotik venlerdeki venöz varyasyonların doğru tanımlanması, baş ve boyun cerrahilerinde potansiyel komplikasyonların önlenmesi ve girişimsel işlemlere kılavuzluk etmesi bakımından önem taşımaktadır. Bu çalışma, 2023-2024 yılları arasında Namık Kemal Üniversitesi Tıp Fakültesi Hastanesi'nde, kontrastlı manyetik rezonans venografi kullanılarak 200 olgu, toplamda 400 hemisfer üzerinde gerçekleştirilmiştir. Çalışmaya, serebral patoloji veya cerrahi müdahale geçirmemiş, artefaktif görüntülere sahip olmayan, 18 yaş ve üzeri bireyler dahil edilmiştir. Sonuçlar, superior sagittal sinüsün en sık sağa deviye olduğunu ve ortalama deviasyonun 2,72±3,35 mm olduğunu, erkeklerde daha belirgin olduğunu göstermektedir. İnferior sagittal sinüs %12 oranında vizualize edilememiştir. Torkular herofili gruplarında en sık karşılaşılan tipin IIA1 olduğu belirlenmiştir. Kadınlarda split straight sinüs oranı erkeklere göre daha yüksek bulunmuştur. Split stright sinüs tip IIC ve IID torkular herofili tipiyle ilişkilendirilmiştir. Split superior sagittal sinüs varlığında ise tip IIC ve IIE torkular herofili tipi yüksek oranda gözlemlenmiştir. Transvers sinüslerde en sık kodominanslık, ikinci sırada ise sağ transvers sinüsün dominans olduğu tespit edilmiştir. Erkeklerde, sol dominans transvers sinüs ve sol dominans sigmoid sinüs oranları kadınlara kıyasla daha yüksek bulunmuştur. Oksipital sinüslerin, en sık sağ internal juguler vene drene olduğu tespit edilmiştir. Silvian venin %3 oranında izlenmeyebileceği saptanmıştır. Her iki hemisferde de Silvian venin sfenoparietal tipte drenajının daha sık olduğu tespit edilmiştir. 50-59 yaş aralığında, sol hemisferde Trolard ve Labbe veni dominanslığının anlamlı derecede yüksek olduğu saptanmıştır. Sonuç olarak, intrakranial venöz yapıların görüntülenmesinde dijital subtraksiyon anjiyografisinin altın standart yöntemdir. Dijital substraksiyon anjiografisinin daha invazif bir yöntem olması nedeniyle kontrastlı manyetik rezonans venografi yöntemi ve Maksimum İntensite Projeksiyon yönteminin destekleyici olarak kullanılması venöz anatomiyi ve varyasyonları tespit etmek amacıyla etkin bir şekilde kullanılabilmektedir. Bu yöntem ile tespit edilen varyasyonların iyi bilinmesi varyasyonların patolojik olarak tanımlanmaması ve invazif işlemlere kılavuzluk etmemesi açısından oldukça önemlidir.The accurate identification of venous variations in the dural venous sinuses and superficial cortical anastomotic veins is crucial for preventing potential complications in head and neck surgeries and for guiding interventional procedures. This study was conducted between 2023 and 2024 at Namık Kemal University Faculty of Medicine Hospital, using contrast-enhanced magnetic resonance venography. A total of 200 cases, covering 400 hemispheres, were included. The study participants were individuals aged 18 and above, with no history of cerebral pathology or surgical intervention, and without any artifacts in the images. The results indicate that the superior sagittal sinus is most commonly deviated to the right, with an average deviation of 2.72±3.35 mm, which is more pronounced in males. The inferior sagittal sinus was not visualized in 12% of cases. In the Torcular Herophili groups, the most frequent identified type was IIA1. The rate of split straight sinus was higher in females compared to males. Split straight sinus was found to be associated with type IIC and IID Torcular Herophili type. In cases with split superior sagittal sinus, Torcular Herophili type IIC and IIE were observed at a higher frequency. Co-dominancy of the transvers sinuses was most common, followed by dominance of the right transverse sinus. In males, the rates of left-dominant transverse sinus and left-dominant sigmoid sinus were found to be higher than in females. It was determined that the occipital sinuses most frequently drain into the right internal jugular vein. The Silvian vein was not visualized in 3% of the cases. In both hemispheres, the drainage of the Silvian vein was most commen in to the sphenoparietal sinus (sphenoparietal type). In the 50-59 age group, dominancy of the Trolard and Labbe veins in the left hemisphere was found to be significantly higher. In conclusion, digital subtraction angiography is the gold standard method for imaging intracranial venous structures. However, due to the more invasive nature of digital subtraction angiography, the use of contrast-enhanced magnetic resonance venography and Maximum Intensity Projection methods as complementary techniques can effectively aid in identifying venous anatomy and variations. A thorough understanding of the variations detected using this method is crucial to avoid misinterpreting them as pathological conditions and to ensure that they do not cause problems during the performance of invasive procedures

Thyme Essential Oil Supplementation in Growing Merino Lambs: Effects on Growth Performance, Blood Metabolites, and Fecal Microbiology
No full textThe study was conducted to evaluate the effect of thyme essential oil on growth performance, fecal microflora and immune system parameters in growing Merino lambs to investigate its use as safe and natural method. Thirty Merino lambs were used in 45 days in a randomized complete block design. The lambs in control group did not receive thyme essential oil, whereas each lamb in experimental groups supplemented with 250 mg thyme essential oil/d (T250) and 500 mg thyme essential oil/d (T500) throughout the study. The number of coliform bacteria was found to be the lowest in the T250 group compared to the other groups. Moreover, a significant difference was found between the control and experimental groups in the Lactobacillus (p < 0.019) and Bifidobacterium (p < 0.010) counts, and it was determined that the experimental groups contained higher numbers of beneficial bacteria than the control group. Immunoglobulin G plasma levels was highest in the 500 mg/day thyme oil group compared to the other groups. In conclusion, adding thyme essential oil with a high carvacrol content to lamb rations under stress following weaning has demonstrated that it can have antibacterial, immune-supportive, and growth-promoting properties without causing a negative effect on performance parameters.Tekirdag Namik Kemal University Scientific Research Unit; DAK Tarim Urunleri Ticaret ve Limited Sirketi; [NKUBAP.10]; [23.478]This study was funded by the Tekirdag Namik Kemal University Scientific Research Unit, Project No: NKUBAP.10.GA.23.478.

A memristor-based Liénard Oscillator design
Full text linkThe new circuit element memristor can be used in the construction of sensors and in circuit applications such as cellular neural networks, chaotic systems, programmable analog circuits, and non-volatile memory devices. Li & eacute;nard equations was proposed by Alfred-Marie Li & eacute;nard in 1928 for modeling oscillating circuits. Semiconductor technology was not available when the first Li & eacute;nard Oscillator was made, but, today, various semiconductor circuit elements are used in the construction of new types of Li & eacute;nard oscillators. Nowadays, there are Carbon-based memristors sold on the market produced by Knowm company. According to the literature review done, there is not any Carbon Knowm memristor-based Li & eacute;nard oscillators made yet. The purpose of this work is to present a new type of Li & eacute;nard Oscillator to the literature by using two Carbon based Knowm memristors. In this study, first, a memristor-based Li & eacute;nard Oscillator circuit topology was proposed, the equations describing the circuit is given, then the circuit was built using a Carbon-based memristor integrated circuit, and the experiments were performed on the assembled oscillator to show that Li & eacute;nard oscillator can be made using two anti-parallel Carbon-based Knowm memristors for the first time in the literature
Determination of Optimum Alkali Reagent for Cocoa Powder Alkalization: Effects on Physico-chemical, Functional and Technological Characteristics
No full textIn this study, alkalized cocoa powders were obtained by optimization study with the Mixture Design, which included the use of the main alkali salts (NaOH, KOH and K2CO3). The effects of the alkali salt(s) used on the antioxidant activity (DPPH and ABTS methods), total phenolic compounds, particle size distribution, physicochemical (pH, moisture content, water activity, total ash amount, color) and volatile component profiles of samples were investigated. Significant models with high R-2 values (0.8297-0.9983) were determined for all main alkalization indicators (a*/b*, pH, and TrMP/TMP), color characteristics, Sauter mean (D3:2), bulk and tapped density (p < 0.05). It has been determined that classification based only on pH and color properties in alkalization may cause disadvantages in terms of polyphenol content and aroma profile, which are among the main motivation factors for consumption of cocoa-based products. In addition, the effects of alkalis on stability and technological properties should also be taken into consideration for this process
Determining the knowledge, attitudes, and behaviors of parents with children aged 6 to 18 regarding the human papillomavirus vaccine
Full text linkAmaç: HPV aşısının 2006 yılı itibariyle kullanıldığı bölgelerde HPV ile ilişkili kanserlerde azalmalar sağlanmıştır. Çalışmamızda Namık Kemal Üniversite Hastanesi genel çocuk polikliniğine başvuran ve 6-18 yaş arası çocuğu bulunan ebeveynlerin HPV aşısı hakkında bilgi, tutum ve davranışlarının değerlendirilmesi amaçlanmıştır. Yöntem: Tekirdağ Namık Kemal Üniversitesi Tıp Fakültesi Hastanesi genel çocuk polikliniği birimine başvuran 6-18 yaş arasında olan 333 çocuğun ebeveynleri ile gerçekleştirilmiştir. Katılımcılara sosyodemografik verilerini sorgulayan, bilgilerine ve tutumlarına yönelik sorulardan oluşan anket uygulandı. Çalışmada elde edilen bulgular değerlendirilirken, istatistiksel analizler için SPSS 26 (Statistical Package for the Social Sciences) programı kullanıldı. Bulgular: Katılımcıların ebeveynlerinden %81,4'ü (n=271) annesi, %18,6'sı (n=62) babası anket sorularına yanıt vermiştir. Annelerin eğitim durumu incelendiğinde %31,5'i (n=105) üniversite ve %3,9'u (n=13) yüksek lisans-doktora mezunudur. Babaların eğitim durumu incelendiğinde %32,7'si (n=109) üniversite ve %3,1'i (n=10) yüksek lisans-doktora mezunudur. Gelir durumu incelendiğinde, katılımcıların %13,5'i (n=45) 10.300 TL veya altında, %48'i (n=160) 10.300-33.750 TL arasında, %38,4'ü (n=128) ise 33.750 TL üzerinde gelire sahiptir. Katılımcıların %16,8'inin çevresinde rahim ağzı kanseri tanısı alan birey bulunmaktaydı ve HPV aşısı hakkında bilgisi olduğunu ifade eden 122 kişi (%36,6) vardı. Verilen cevaplara göre aşı hakkında bilgi edinme kaynağı olarak en çok hekim, onu internet ve sosyal medya takip etmekteydi. Sadece 6 ebeveyn (%1,8) çocuğuna HPV aşısı yaptırmıştı. Aşı yaptırmama nedeni olarak aşı hakkında yeterli bilgi sahibi olmamak birinci sırada yer almaktaydı. %93,1 katılımcı HPV aşısının ulusal aşı takviminde yer alması gerektiğini, %89,8'i ulusal aşı takviminde yer alsa aşıyı çocuklarına yaptıracaklarını, %86,2'si ise aşıyı başkalarına önerebileceklerini söylediler. HPV aşısı hakkında bilgi sahibi olma ile ebeveyn eğitimi ve hane gelir düzeyi arasında anlamlı ilişki bulunmuştur. Çocuğu HPV aşısı ile aşılanan ebeveynlerin hane gelirleri arasında anlamlı ilişki bulunmuştur. Sonuç: Çalışmamıza katılan ebeveynlerin HPV enfeksiyonu ve HPV aşısı bilgi düzeyleri düşük saptanmıştır. Halkın bilgilendirilmesi için özellikle koruyucu sağlık hizmeti veren sağlık kurumlarına büyük sorumluluk düşmektedir. Aşının ulusal aşılama takviminde yer alması durumunda çocuklarına aşı yaptırmayı düşünen ebeveyn sayısı göz önüne alındığında diğer ülkelere yakın başarıların elde edilebilmesi için aşının ücretsiz olması ve koruyucu sağlık hizmeti veren hekimlerinin aşı ile ilgili bilgilendirme yapmasının çok önemli olduğu sonucunu ortaya koymuştur.Since 2006, regions where the HPV vaccine has been implemented have shown reductions in HPV-related cancers. This study aims to evaluate the knowledge, attitudes, and behaviors of parents with children aged 6-18 who visit the general pediatric clinic at Namık Kemal University Hospital regarding the HPV vaccine. Method: The study was conducted with the parents of 333 children aged 6-18 who visited the general pediatric clinic at Tekirdağ Namık Kemal University Faculty of Medicine Hospital. Participants completed a questionnaire that included questions about their sociodemographic data, knowledge, and attitudes. The findings obtained in the study were analyzed using the SPSS 26 (Statistical Package for the Social Sciences) software for statistical evaluation. Findings: Among the participants, 81.4% (n=271) of the responses were provided by mothers, and 18.6% (n=62) by fathers. When examining the educational status of mothers, 31.5% (n=105) had a university degree, and 3.9% (n=13) had completed postgraduate or doctoral studies. Regarding fathers' educational status, 32.7% (n=109) had a university degree, and 3.1% (n=10) had completed postgraduate or doctoral studies. In terms of income, 13.5% (n=45) of participants had an income of 10,300 TL or less, 48% (n=160) had an income between 10,300 TL and 33,750 TL, and 38.4% (n=128) had an income above 33,750 TL. 16.8% of participants had someone in their surroundings who had been diagnosed with cervical cancer, and 36.6% (n=122) stated that they were knowledgeable about the HPV vaccine. According to the responses, the most common source of information about the vaccine was healthcare professionals, followed by the internet and social media. Only 6 parents (1.8%) had vaccinated their child against HPV. The most common reason for not vaccinating was lack of sufficient knowledge about the vaccine. 93.1% of participants stated that the HPV vaccine should be included in the national vaccination schedule, 89.8% said they would vaccinate their children if it were included in the national schedule, and 86.2% said they would recommend the vaccine to others. A significant relationship was found between knowledge about the HPV vaccine and parental education level and household income. A significant relationship was also observed between household income and parents who had vaccinated their child against HPV. Conclusion: The level of knowledge about HPV infection and the HPV vaccine among the parents participating in our study was found to be low. Health institutions, particularly those providing preventive health services, have a significant responsibility in educating the public. Considering the number of parents who would consider vaccinating their children if the vaccine were included in the national vaccination schedule, it can be concluded that to achieve success similar to other countries, the vaccine should be provided for free and healthcare professionals offering preventive services must play an essential role in informing about the vaccine
Knockdown of miR-182 changes the sensitivity of triple-negative breast cancer cells to cisplatin
No full textBreast cancer is the most common malignancy that affects women. MicroRNAs (miRNAs) play an essential role in cancer therapy and regulate many biological processes such as cisplatin resistance. The study's objective was to determine whether miR-182 dysregulation was the cause of cisplatin resistance in TNBC cell line MDA-MB-231. To determine the expression of miR-182, PCR was performed with primers specific to miR-182, and agarose gel electrophoresis was performed. To reduce the expression of miR-182 in MDA-MB-231 cells, anti-miR-182 oligonucleotides were used. RT-qPCR was used to confirm knockdown. The knockdown and control groups were treated with cisplatin at the same time. Propidium iodide (PI) and Annexin V staining were performed for apoptosis assay. Flow cytometric analysis was used to investigate the effect of miR-182 knockdown on cell cycle arrest. In comparison to untreated control MDA-MB-231 cells with MDA-MB-231 cells treated with anti-miR-182, there was a significant increase in the cisplatin-induced early apoptosis phase (p = 0.023). Also, inhibition of miR-182 significantly increased the cell cycle arrest at the G2/M phase in MDA-MB-231 cells (p = 0.031). Our results revealed that miR-182 inhibition may play a role in the overcoming of cisplatin resistance by inducing apoptosis and, cell cycle arrest in TNBC
