    (Publishing Office of the University of Rzeszow, 2024) Tanrıverdi, Seher; Şen, Mehmet Ali; Genç, Hasan; 09.06. Department of Social Services/ Sosyal Hizmet Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
    Introduction and aim. In patients waiting for organ transplantation, increased waiting time can increase anxiety by creating negative automatic thoughts. The aim of this study is to examine the relationship between corneal transplant recipients' negative automatic thoughts and anxiety before organ transplantation. Material and methods. The population of this correlational descriptive study consisted of 108 patients waiting for cornea transplantation in the Eye Bank unit of a hospital in the south east region of Türkiye. The data were obtained from the patients presented to the ophthalmology clinic for transplantation between September and December 2022. A patient information form, the Negative Automatic Thoughts Scale, and the Trait Anxiety Scale were used to collect the data. Percentage distribution, arithmetic mean, logistic regression and correlation analysis were used in the data analysis. Results. It was determined that the mean score of the negative automatic thoughts of the transplant patients participating in the study was 100.69±47.83, and the trait anxiety mean score was 53.06±6.07. There was a positive relationship between negative automatic thoughts and trait anxiety at a moderate level, which was statistically significant (p<0.05, r=0.53). Conclusion. It was determined in the study that the patients' negative automatic thoughts and trait anxiety were high, and their anxiety increased as the negative automatic thoughts increased.

    The Effect of N-acetylcysteine on Amylase, Electrolytes, Vitamins and Nitrosative Stress Levels in Rats Treated with Maras Powder
    (Eastern Journal of Medicine, 2020) Unsal, Velid; Belge Kurutaş, Ergül; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
    The aim of this study is to investigate the effects of N-acetylcysteine (NAC) on amylase, electrolytes, vitamins and nitrosative stress levels in the plasma of rats treated with smokeless tobacco "maras powder". Our study consisted of three groups. Control (n = 10), the group using maras powder (n = 10), maras powder+ NAC group. To the Maras powder group, 200 mg maras powder was placed in the sublingual area under general anesthesia. It was waited for 15 minutes for Maras powder to be absorbed through mucosa. This procedure was repeated once a day and for 7 days. To the NAC group, 200 mg of Maras powder was given as in the Maras powder group and NAC was injected intraperitoneally with a dose of 100 mg / kg / day. On the 8th day, the levels of amylase, vitamins (A, C and E), electrolytes (Na+, K+, Cl- ) and, as the biomarkers of nitrosative stress, nitric oxide (NO) and nitrotyrosine (3-NTx) in the plasma of all three groups were measured by the methods of ELISA. It was determined that amylase, 3-NTx, NO, electrolyte levels increased in the group using Maras powder compared to the control and NAC groups, but vitamin levels decreased. (p <0.05). It was detected that the levels of amylase, 3-NTx, NO, electrolyte in the group treated with NAC decreased compared to the group using Maras powder, whereas vitamin levels significantly increased and approached to the values of the control group. Smokeless tobacco 'Maras powder' increases nitrosative stress and distorts the levels of vitamin A, E, C and electrolyte in the plasma. NAC has a positive function in reducing the damage caused by Maras powder.

    Experimental and theoretical investigation of adsorption and inhibition properties of 2-Amino-1,3,5-triazine-4,6-dithiol against corrosion in hydrochloric acid solution on mild steel
    (Elsevier, 2023) Arslanhan, Selim; Yıldız, Reşit; Döner, Ali; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
    In this work, 2-Amino-1,3,5-triazine-4,6-dithiol (2-ATD) as novel and high efficiency corrosion inhibitor has been investigated for mild steel (MS) corrosion in 0.5 M HCl solution using electrochemical methods, scanning electron microscopy (SEM), energy disperse X-ray spectroscopy (EDX), atomic force microscopy (AFM) and quantum chemical calculation methods. Potentiodynamic polarization (PDP) curves indicate that 2-ATD is mixed type inhibitor, corrosion inhibition efficiency increased with increasing inhibitor concentration and reached its value of 96.5%. Evolution of exposure time versus corrosion behavior of 2-ATD is examined in corrosive medium. While corrosion potential (Ecorr) shifted more negative values, polarization resistances (Rp) decreased after 120 h exposure time due to the corrosion process. H2 volume is measured in uninhibited and inhibited solutions (10 mM 2-ATD) after 120 h exposure time. Very low volume (3.6 mL cm-2) of H2 is obtained on MS electrode in inhibited solution after 120 h of exposure, indicating that 2-ATD covers the entire surface against aggressive attack and retards the both anodic dissolution of MS and cathodic hydrogen evolution reactions. The adsorption process proposal is the Langmuir isotherm which is most suitable. Adsorption and thermodynamic parameters show that 2-ATD has a strong adsorption effect onto MS surface and includes mixed adsorption style (physical and chemical). Corrosion current density increases with increasing temperature and high activation energy (Ea) proves the strong adsorption of 2-ATD on the MS surface. Anti-corrosion mechanism of 2-ATD is described more detail with the potential of zero charge method. SEM, EDX and AFM analysis support the obtained results of electrochemical methods and confirm the existence of protective layer and strong adsorption of 2-ATD on the MS surface. Chronoamperometry test shows that current densities are almost constant whole experiment in the presence of organic film. Finally, quantum chemical calculation method of 2-ATD in blank solution is performed to investigate the active sites for possible attachment with MS surface.

    Investigation of the effects of Alfa lipoic acid on changes in maternal rat kidney caused by tobacco smoke exposure in pregnancy [Gebelikte Tütün Dumani Maruziyetinin Anne Siçan Böbrek Dokusunda Meydana Getirdigi Degişiklikler Üzerine Alfa Lipoik Asitin Etkilerinin İncelenmesi]
    (Ataturk Universitesi, 2019) Erdem Güzel E.; Kaya N.; Ozan Kocamüftüoglu G.; Dabak D.Ö.; Temizer Ozan P.S.; Ozan I.E.; 09.02. Department of Midwifery/ Ebelik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
    Çalışmada gebelikte tütün dumanına maruz kalan anne sıçanların böbrek dokusunda meydana gelen histopatolojik sonuçlar üzerine Alfa lipoik asitin etkilerinin deneysel olarak araştırılması amaçlandı. 28 adet dişi Sprague-Dawley cinsi sıçan kullanıldı. Gebe sıçanlar; Kontrol grubu, Tütün dumanı (TD) grubu, Tütün dumanı + Alfa lipoik asit (TD+ALA) grubu ve Alfa lipoik asit (ALA) grubu olmak üzere rastgele dört eşit gruba ayrıldı. TD ve TD+ALA grubundaki sıçanlar çiftleşmeden önce sekiz hafta ve gebelik süresince günde iki saat tütün dumanına maruz bırakıldı. TD+ALA ve ALA grubundaki sıçanlara ise çiftleşmeden önce sekiz hafta ve gebelik süresince gün aşırı gavaj yolu ile 20 mg/kg ALA verildi. Deney sonunda çıkarılan böbrek dokuları histolojik, immünohistokimyasal ve MDA düzeyi tayini metotları kullanılarak incelendi. TD grubuna ait böbrek kesitlerinde inflamatuar hücre artışı, Bowman boşluğunda artış, tübül lümeninde hiyalin birikimi gibi histopatolojik bulgulara rastlandı. ALA uygulaması ile histopatalojik bulguların büyük bir çoğunluğunda azalma gözlendi. TD grubunda VEGF immünreaktivitesinin kontrol grubuna göre anlamlı artış gösterdiği, TD+ALA grubunda ise TD grubuna göre anlamlı derecede azaldığı belirlendi. MDA seviyelerinde ise TD grubunda, kontrol grubuna göre anlamlı artış olduğu tespit edildi. Sonuç olarak, gebelik boyunca tütün dumanı maruziyetinin böbrek dokularında histopatolojik hasara ve damarlanmada artışa neden olduğu, ALA’nın ise bu etkilere karşı kısmen koruma sağladığı belirlendi.
