Synthesis and structural characterization BODIPY-based compounds for fluorescence sensing of β-amyloid aggregates
No full textAlzheimer's disease (AD) is a neurodegenerative disorder associated with aging. According to the amyloid cascade hypothesis, the aggregation and accumulation of beta-amyloid (A beta) peptides in the brain as A beta plaques is a critical process in the pathogenesis of AD. Among the existing diagnosis methods, fluorescence detection of beta-amyloid (A beta) has emerged as an alternative method due to its advantages such as real-time detection, low cost, not exposed to radiation, and high resolution for early diagnosis of Alzheimer's disease (AD). In this study, we designed and synthesized BODIPY-based compounds (BODIPY-3, BODIPY-4 and BODIPY-5) for the fluorescence detection of A beta aggregates. In the fluorescence studies for detecting A beta, BODIPY-5 with the squaric acid ester unit at the meso position of the BODIPY core showed a promising effect with an 11.7 mu M Kd value.TUBITAK (The Scientific and Technological Research Council of TURKIYE) 2214-A- International Research Fellowship Programme for PhD Students; Kahramanmaras Sutcu Imam University Research Unit [2020/6-22 M, 2020/1-12D]; Higher Education Council Research BoardThis work was financially supported by TUBITAK (The Scientific and Technological Research Council of TURKIYE) 2214-A- International Research Fellowship Programme for PhD Students.

New Trends in Economic Security Policies: USA, European Union and Japan
No full textBu çalışmada küresel ekonominin başat aktörleri olarak ABD, Avrupa Birliği (AB) ve Japonya’nın ekonomik güvenliğe ilişkin strateji ve politikaları incelenmektedir. İncelemeye konu olan ülkelerin kritik hammaddelere ve minerallere bağımlılık, enerji arz güvenliği, tedarik zincirlerinin sürekliliği, ileri teknoloji ürünlerinin güvenliğinin sağlanması gibi faktörler açısından durumları ekonomik güvenlik boyutuyla değerlendirilmektedir. ABD’de ekonomik güvenlik ulusal güvenliğin ayrılmaz bir parçası olarak görülmektedir. Bu bakış açısı ekonomi politikalarının biçimlenmesinde etkili olmaktadır. AB’de ekonomik güvenlik, artan ekonomik/finansal ve jeopolitik gerilimler karşısında ortak hareket etme gündemiyle ele alınmış ve Haziran 2023'te Ekonomik Güvenlik Stratejisi kabul edilmiştir. Japonya’da ise enerji ve hammadde tedariki, gıda ve emtia fiyatlarındaki değişiklikler gibi faktörler bu konudaki öncelikleri belirlemektedir. Çalışma sonuçlarına göre, ele alınan ülkelerin ekonomik güvenlik politikalarını ve stratejilerini haklı gösterecek bir takım sorunlarla yüz yüze oldukları görülmektedir. Her üç ülkenin de, kritik mineraller, tedarik zincirlerinin sürekliliği ve kritik teknolojilerin korunması konularında kendilerini yetersiz gördükleri; AB ve Japonya’nın bunlara ilaveten petrol ve doğal gaz tedarikinde önemli ölçüde dışa bağımlı oldukları anlaşılmaktadır.This study examines the strategies and policies of the leading actors of the global economy, the United States, the European Union (EU), and Japan, regarding economic security. The situation of the countries under review in terms of factors such as dependence on critical raw materials and minerals, security of energy supply, continuity of supply chains, and ensuring the security of high-tech products has been evaluated in terms of economic security. In the United States, economic security is seen as an integral part of national security, and this perspective is effective in shaping economic policies. In the EU, economic security has been addressed with the agenda of joint action against increasing economic/financial and geopolitical tensions, and the Economic Security Strategy was adopted in June 2023. In Japan, factors such as energy and raw material supply, changes in food and commodity prices determine the priorities in this regard. According to the conclusion reached in the study, it is seen that the countries under review face a number of problems that will justify their economic security policies and strategies. It is understood that all three countries see themselves as inadequate in terms of critical minerals, continuity of supply chains and protection of critical technologies; in addition to these, the EU and Japan are significantly dependent on other countries for oil and natural gas supplies

According to the findings, job satisfaction does not differ by gender or age. Significant relationships were found between basic psychological need satisfaction, organizational commitment, and job satisfaction among healthcare workers. Basic psychological needs and organizational commitment predict job satisfaction, and basic psychological needs also predict organizational commitment. Furthermore, the study identified the mediating role of organizational commitment in the relationship between basic psychological needs and job satisfaction. The findings were discussed in the context of the existing literature
The Relationship Between Uric Acid and Mortality in Hemodialysis Patients
No full textIntroductionUric acid, the end product of purine metabolism, is an antioxidant molecule. Both low and high serum uric acid levels are associated with increased mortality. The aim is to investigate the relationship between serum uric acid levels and mortality in hemodialysis patients. MethodsThis retrospective study was conducted on hemodialysis patients in Hatay, Turkey, between 2010 and 2023. Records were reviewed, and serum uric acid levels, other laboratory tests, and hemodialysis duration were noted. Patients on hemodialysis for at least 3 months were included. A p-value of less than 0.05 was considered statistically significant. FindingsA total of 3443 hemodialysis patients were included. The average age was 64.39 +/- 13.57 years (minimum: 18 years, maximum: 90 years), and 58% were male. The mean serum uric acid level was 6.23 +/- 1.43 mg/dL (range: 0.1-16). The prevalence of hyperuricemia was 39.3%, and hypouricemia was 0.2%. The median parathyroid hormone (PTH) value was lower in the group with a serum uric acid level 7 mg/dL (p 7 mg/dL (p < 0.001). DiscussionLow serum uric acid levels have been associated with increased mortality; this may be because serum uric acid is an indicator of nutritional status. Higher serum uric acid levels were associated with higher PTH levels; further studies are needed to elucidate the causal relationship. Low serum uric acid levels were associated with an increased risk of cerebrovascular disease

Assessment of Medical Students' Knowledge Levels on HIV/AIDS: A Single-Center Study
No full textAim: Medical and dental students in various countries have demonstrated varying levels of knowledge and attitudes towards HIV/AIDS. Although many students are aware of HIV/AIDS, studies show significant gaps in knowledge about transmission modes and prevention techniques. This study assesses the knowledge of HIV/AIDS among medical students at a single institution in Turkey. The aim of the study is to evaluate the knowledge levels and awareness of medical students regarding HIV/AIDS. Materials and Methods: The study included 172 students from Sivas Cumhuriyet University. A questionnaire with 26 questions, including 23 knowledge-based and 3 demographic questions, was administered via Google Forms. Statistical analysis was performed using chi-square tests to evaluate associations between class years and correct responses. Results: The majority of students demonstrated gaps in knowledge, particularly in the modes of transmission and prevention. For instance, 61% of participants believed incorrectly that mosquitoes can transmit HIV. Only 50% correctly identified that HIV can be transmitted from mother to child. Students in the third year had higher correct response rates compared to other years. Conclusion: Despite overall awareness of HIV/AIDS, medical students showed significant gaps in their understanding. The medical curriculum should include more extensive education on HIV/AIDS, particularly in terms of transmission, prevention, and treatment.[No abstract available
Gelation of different phases of probiotic-loaded water-in-oil-in-water emulsion to enhance probiotic survival stability
No full textThis study aimed to develop water-in-oil-in-water (W1/O/W2) double emulsion gels (DEGs) with Lactiplantibacillus plantarum subsp. plantarum and Limosilactobacillus reuteri encapsulated within the inner aqueous phase (W1), with a focus on improving probiotic viability under adverse environmental conditions. The system incorporated gelling agents to enhance emulsion stability, including whey protein crosslinked with calcium chloride to gel the W2 phase and carnauba wax as an oleogelator to solidify the O phase. Three formulations were investigated: W2-gelled, O-gelled, and dual-phase gelled systems. Our study demonstrated that designed DEGs loaded with probiotics effectively maintained cell count in a sufficient amount (more than 6 log CFU/g) during 56-day storage, heat treatment (at 60 degrees C and at 72 degrees C for 1 hr), and four freezing-thawing cycles compared to free cells. During simulated digestion, free probiotic cells exhibited substantial cell reduction, particularly after intestinal digestion, with cell loss ranging from 3.00 to 3.50 lg colony forming unit (CFU)/g. However, encapsulation within DEGs effectively enhanced probiotic survival, minimising cell reduction throughout digestion with cell loss around 1 lg CFU/g. These findings highlight the practical application of W/O/W phase-specific gelling agents to enhance structural integrity and probiotic survival. The DEG matrix outperforms traditional encapsulation, providing superior probiotic stabilisation under stressors.Research Council of Lithuania (LMTLT) [S-A-UEI-23-1]This project has received funding from the Research Council of Lithuania (LMTLT), agreement no.

No full textAim: To conduct and report on psychometric tests for a valid and reliable measurement tool for evaluating digital hospitals by healthcare professionals. Method: This psychometric study took place in a public digital hospital in Turkey. It was carried out with the participation of 355 healthcare professionals. Data were collected between September and October 2023 using an online survey and non-probability convenience sampling method. Statistical Package for Social Science Version (SPSS) 26.0 and analysis of moment structures version 24.0 were used to analyse the data. It was used for the psychometric properties and analyses of the scale (item analysis, explanatory factor analysis, confirmatory factor analysis (CFA), convergent and divergent validity statistics, Cronbach Alpha internal consistency coefficient, dependent sample t-test, and intraclass correlation). Results: The content validity index of the scale is 0.92. As a result of exploratory factor analysis (EFA) and CFA in separate samples, a total of 30 items and four sub-factors were obtained. Cronbach Alpha value of the scale is over 0.90 for both samples. In the four-factor structure, 82.64% of the total variance was explained. The 30-item and four-factor structure obtained in EFA was confirmed in CFA, and convergent and divergent validity statistics were provided. Test-retest results showed that the scale has high reliability. Conclusion: The digital hospital evaluation scale is valid and reliable for healthcare professionals to evaluate digital hospitals
