Bullying in the Kitchen: A Research on Culinary Interns
No full textTicari mutfaklar, ağırlama sektöründe, çalışan devir hızının yüksek olmasının önemli sorun yarattığı departmanlardan biridir. Bu nedenle iş memnuniyetsizliği veya bırakmaya neden olan sebeplerin araştırılması gerekmektedir. Bu sebeplerden biri olan zorbalık konusu öne çıkan argümanlardan biri olarak alanyazında sıkça bahsedilmiştir. Bu araştırmanın amacı da mutfak stajyerlerinin zorbalığa uğrayıp uğramadığını ve bunun iş tatmini düzeylerini ve işten ayrılma niyetlerini nasıl etkilediğini bulmaktır. Buna ek olarak cinsiyet değişkenine dayalı zorbalığa maruz kalmada farklılıkların olup olmadığı da incelenmiştir. Örneklem, Türkiye'nin İzmir kentindeki 5 farklı kamu ve özel üniversitesinin mutfak sanatları, gastronomi ve/veya aşçılık programları lisans ve önlisans öğrencilerinden oluşmaktadır. Veriler, Eylül-Aralık 2023 tarihleri arasında 129 mutfak stajyerinden toplanmış; regresyon ve t-testi analizleri için SPSS kullanılmıştır. Ampirik sonuçlar, stajyerler arasında orta düzeyde zorbalığa maruz kalma olduğunu; kadın stajyerlerin mutfakta erkek meslektaşlarından daha fazla zorbalığa maruz kaldığını ve zorbalığın tüm stajyerler arasında işten ayrılma niyetini artırırken iş tatmini düzeylerini düşürdüğünü göstermiştir. Bu çalışma; yiyecek ve içecek işletmelerine stajyerler için iyi planlanmış bir eğitim programı geliştirme ve iş tatminini artırmak ve işgücü devir oranını azaltmak için olumlu bir çalışma ortamı yaratma konusunda yol gösterici olmayı amaçlamaktadır. Konu, ağırlama sektörü için yeni olmasa da mutfak stajyerleri arasında zorbalık konusunda yapılan az sayıda araştırma olduğu görülmektedir. Bu nedenle özellikle mutfakta zorbalık bağlamında literatüre katkıda bulunulması amaçlanmaktadır
Covid-19 With Woman Academicians' Perspective in Türkiye: Hopelessness and Well-Being
No full textThis study aimed to determine the hopelessness and well-being levels of woman academics during the COVID-19 pandemic. This cross-sectional and analytical study was conducted online between February and May 2022 at the end of the fourth wave of the COVID-19 pandemic. The study was conducted with 341 woman academics from state and foundation universities in T ; uuml;rkiye. The mean score from the Beck Hopelessness Scale was 6.02 +/- 4.84, and the mean score from the Flourishing Scale (FS) was 43.50 +/- 7.24. There was a significant negative correlation between flourishing scores and low, mild, moderate, and high hopelessness scores (p = .038, p .001, p = .001, p = .034, respectively); as participants' level of hopelessness increases, their FS scores decrease significantly (r: -.689, p .001). Revealing the effects of changes in the routine and academic activities of woman academics on hopelessness and well-being during the COVID-19 pandemic process has the potential to reduce possible risks that may develop in pandemics, and contribute to reducing the hopelessness levels and increasing well-being of woman academics
Novel Approach Methodologies in Modeling Complex Bioaerosol Exposure in Asthma and Allergic Rhinitis Under Climate Change
No full textThe undeniable impact of climate change and air pollution on respiratory health has led to increasing cases of asthma, allergic rhinitis and other chronic non-communicable immune-mediated upper and lower airway diseases. Natural bioaerosols, such as pollen and fungi, are essential atmospheric components undergoing significant structural and functional changes due to industrial pollution and atmospheric warming. Pollutants like particulate matter(PMx), polycyclic aromatic hydrocarbons(PAHs), nitrogen dioxide(NO2), sulfur dioxide(SO2) and carbon monoxide(CO) modify the surface and biological properties of atmospheric bioaerosols such as pollen and fungi, enhancing their allergenic potentials. As a result, sensitized individuals face heightened risks of asthma exacerbation, and these alterations likely contribute to the rise in frequency and severity of allergic diseases. NAMs, such as precision-cut lung slices(PCLS), air-liquid interface(ALI) cultures and lung-on-a-chip models, along with the integration of data from these innovative models with computational models, provide better insights into how environmental factors influence asthma and allergic diseases compared to traditional models. These systems simulate the interaction between pollutants and the respiratory system with higher precision, helping to better understand the health implications of bioaerosol exposure. Additionally, NAMs improve preclinical study outcomes by offering higher throughput, reduced costs and greater reproducibility, enhancing the translation of data into clinical applications. This review critically evaluates the potential of NAMs in researching airway diseases, with a focus on allergy and asthma. It highlights their advantages in studying the increasingly complex structures of bioaerosols under conditions of environmental pollution and climate change, while also addressing the existing gaps, challenges and limitations of these models.This study is funded by the Presidency of the Republic of Turkey Strategy Budget Department (2019 K12-149080) and the Scientific and Technological Research Council of Turkey (TUBITAK) through 123 M406.Presidency of the Republic of Turkey Strategy Budget Department [2019 K12-149080]; Scientific and Technological Research Council of Turkey (TUBITAK) [123 M406
A Novel Smartphone-Based Nanozyme-Enhanced Electrochemical Immunosensor for Ultrasensitive Direct Detection of Staphylococcus Aureus in Milk and Blood Serum
No full textA graphene quantum dot (GQD)-based nanozyme-enhanced electrochemical sensor was developed for the ultra-sensitive and rapid Staphylococcus aureus detection in PBS, undiluted milk, and blood serum. The S. aureus concentration for immunosensor calibration was electrochemically determined to be 1.24x 10(9) CFU mL(-1) (R-2 = 0.99), utilizing an innovative smartphone-based electrochemical device. Transmission electron (TEM) and atomic force (AFM) microscopy analyses of GQDs revealed uniform nanoparticles (8-10 nm) with surface heights of 2 nm and 21 nm at different scan areas. Fluorescence and Fourier transform infrared spectroscopy spectra showed an emission at 530 nm with an excitation wavelength of 485 nm, along with the presence of hydroxyl, carboxyl, and aromatic groups on the GQD surfaces. The maximum current peak for GQDs was obtained by optimizing electrochemical properties through amperometry at +0.9 V. The optimal signal intensity- and limit of detection (LOD)-based GQD concentrations were 0.0125, 0.5, and 1 mg mL(-1) for PBS, undiluted milk, and blood serum, respectively. The optimal antibody concentration for S. aureus detection was 25 mu g mL(-1), resulting in a 91 % amperometric suppression and a 94 % fluorescence quenching. The developed biosensor effectively detected S. aureus, with calculated LODs of 1, 4, and 344 CFU mL(-1) in PBS, undiluted milk, and blood serum, respectively. TEM, AFM, and contact angle analyses confirmed S. aureus binding to the GQD-antibody bioconjugate, shifting surface height to 35 nm and contact angle from similar to 30 degrees to similar to 65 degrees. The immunosensor showed high specificity for S. aureus with minimal cross-reactivity to Listeria monocytogenes, Staphylococcus epidermidis, Enterococcus faecium, and Streptococcus pneumoniae.The authors gratefully acknowledge the support provided by the Bandirma Onyedi Eyluel University Scientific Research Foundation (BAP, Grant number: 24-1004-004) and the Scientific and Technical Research Council of Turkey (TUBITAK) for providing a scholarship (Grant number: 1059B192301157).

Investigating the Impact of the Parameters on the Model of Hiv Infection Including a Cure Rate and Latently Infected Cells
No full textThe main purpose of this study is to explore the impact of problem parameters on three different models of Human Immunodeficiency Virus (HIV) infection. The first model is the most widely studied HIV infection model, involving three groups: uninfected T cells (T), infected T cells (I), and free virus particles (V). The second model includes an additional parameter that accounts for the effect of the cure rate. The third model extends the first by dividing infected cells into two subgroups-latently and actively infected T cells-and thus includes four nonlinear differential equations. These nonlinear systems are solved using the Lucas wavelet method, which offers significant advantages, such as ease of implementation in symbolic computation and effective numerical results. We solve the models for several parameter values and discuss the impact of these parameters on the course of HIV infection in detail. Due to the absence of an analytical solution, we examine the accuracy through residual error calculation and compare our results with other numerical results available in the literature, presenting them in the form of tables and figures
Preventative Effect of Montelukast in Mild To Moderate Contrast-Induced Acute Kidney Injury in Rats Via Nadph Oxidase 4, P22phox and Nuclear Factor Kappa-B Expressions
No full textBaris, Elif/0000-0001-6838-7932; Simsek, Oguzhan/0000-0003-2756-8440Reactive oxygen species (ROS) generation, inflammation and apoptosis are observed in contrast-induced acute kidney injury (CI-AKI). NOX4, isoform of NADPH oxidase main regulatory enzyme for ROS generation, is mostly expressed in the kidney and co-localized with p22phox. It is investigated the effect of antioxidant, anti-inflammatory and anti-apoptotic montelukast pre-treatment on expression of NOX4, p22phox and NF-kappa B in preventing CI-AKI in rats in this study. Wistar male rats randomized into four groups: 1. Control (C), 2. CI-AKI (iohexol; 3 g iodine/kg), 3. Montelukast (10 mg/kg) (M), 4. M + CI-AKI. Rats sacrificed on the 7th day. Urine and serum creatinine and serum Kidney injury molecule-1 (KIM-1) levels measured. NF-kappa B, NOX-4, p22phox mRNA and protein expressions, TNF-alpha, KIM-1 mRNA expressions, ROS and caspase-3 evaluated from kidney tissue. Histological injury scored. ANOVA and Kruskal-Wallis tests were used for analysis parametric and nonparametric data, respectively. p 0.05 considered statistically significant. Tubular injury score, KIM-1 and caspase-3 levels increased in CI-AKI group compared to C group (p 0.05). TNF-alpha, NF-kappa B, NOX-4, p22phox, KIM-1 mRNA expressions and ROS levels increased in CI-AKI group compared to C group (p 0.001 and p 0.05). NF-kappa B, NOX-4, p22phox protein expressions increased in CI-AKI group compared to C group (p 0.05) and decreased in the M + CI-AKI group compared to CI-AKI group (p 0.01, p 0.05, p 0.05). TNF-alpha, NF-kappa B, NOX-4, p22phox, KIM-1 mRNA expressions and ROS levels decreased with montelukast pre-treatment (p 0.001). One of the mechanism of increased ROS level in the CI-AKI model is related the increase the expression of NOX4 and p22phox and montelukast pre-treatment has a protective effect by decreasing NOX4 and p22phox mRNA and protein expressions.Dokuz Eylul University Research Foundation [2019.KB.SAG.068]This project was supported by Dokuz Eyluel University Research Foundation with the grant number 2019.KB.SAG.068
Conceptualising Social Gastronomy Movement From the Perspective of Social Gastronomy Initiatives
No full textAlthough hunger and wasting food are two contradicting terms, both food-related issues stand as significant topics on the agenda of various stakeholders. One-third of the food that is produced is wasted along the food chain and one in nine people suffer from hunger. Chefs and food and beverage professionals also feel responsible to fight against these global threats and adopt the principles of sustainable development goals. They use the power of food and engage in social responsibility and social gastronomy practices to make things better for everyone; the vulnerable part of the society in particular. The aim of this research is to provide a comprehensive understanding of social gastronomy concept, its objectives, scope and impact as well as best practices by reviewing the literature. The study is based on secondary data analysis. By reviewing the literature and several social gastronomy initiatives and practices, it is aimed to create awareness about what similar practices can be adopted for a sustainable gastronomy; inspire chefs as well as other food professionals about the concept and provide a basis for further researches
