1-(2-Hydroxyethyl)-2-imidazolidinone as corrosion inhibitor of mild steel in 0.5 M HCl solution: thermodynamic, electrochemical and theoretical studies
(Journal of Adhesion Science and Technology, 2019) Keleşoğlu, Ayşen; Yıldız, Reşit; Dehri, İlyas; 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 inhibition effect of 1-(2-Hydroxyethyl)-2-imidazolidinone (2-HEI) on mild steel (MS) corrosion in 0.5M HCl solution was investigated at different inhibitor concentration and temperature by electrochemical experiments, such as linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and quantum chemical calculations. The inhibitor adsorption process on mild steel in 0.5M HCl system was studied at different temperatures (20 C–50 C). Furthermore, the surface morphology of MS was also investigated with SEM in the absence and the presence of inhibitor. The adsorption of 1-(2-Hydroxyethyl)-2-imidazolidinone on MS surface is an exothermic process and this process obeys the Langmuir adsorption isotherm. The Quantum chemical findings are good agreed with the empirical data.
16. Asır Kudüs’ünde Bir İlim Kurumu Taziyye: Medresesi
(Hitit Üniversitesi, 2022) Evsen Aydın, Esra; 05.03. Department of Islamic History and Arts / İslam Tarihi ve Sanatları Bölümü; 05. Faculty of Islamic Sciences / İslami İlimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Üç semavi din için kutsal kabul edilen, bu nedenle tarih boyunca bu üç dine mensup devletlerin şehre hâkim olma mücadeleleri verdiği, yeryüzünde bu özellikte tek şehir olan Kudüs Müslümanlar için de tarihleri boyunca önemli bir konumda olmuştur. İslam idaresinde olduğu her dönemde Mekke ve Medine’den sonra üçüncü harem kabul edilen, tamamı Mescid-i Aksa olarak anılan Harem-i Şerif alanı başta olmak üzere şehrin her köşesinde Müslüman bir kimlik oluşturmak amacıyla imar ve inşa faaliyetleri devam etmiştir. Coğrafi konumu sebebiyle ticaret merkezi özelliği taşımayan, Haçlı seferlerinin olduğu dönem dışında askeri ve siyasi olarak da merkezi bir konumu olmayan Kudüs, Müslümanların hâkim olduğu zamanlarda mukaddes bir dini merkez olmanın yanında önemli bir ilim merkezi özelliği de taşımıştır. Şehirde inşa edilen medreseler, tekke ve zaviyeler, ribâtlar, hankahlar gibi müstakil dini ve ilmi kurumların yanı sıra Mescid-i Aksa’nın kendisi de sadece ibadet için kullanılan bir mescit olmayıp her zaman cami dersleri, zikir meclisleri, mestabe denilen ve avlusunda kurulan ilim halkalarıyla canlı bir ilim merkezi fonksiyonu icra etmiştir. Şehirde ilim kurumlarının tesisi Eyyûbîler döneminde başlayarak Memlükler ile zirveye ulaşmış, Osmanlılar döneminde ise daha çok mevcut sistemin, kurumların ve bu kurumları ayakta tutan vakıfların muhafazasını sağlayan bir siyaset takip edilmiştir. Osmanlı idaresine geçtikten sonra Kudüs’te bulunan medreselerin işleyişini nasıl devam ettirdiği, vakıf müessesesinin kontrolü gibi konuların anlaşılması için Kudüs medreseleri üzerine yapılacak müstakil çalışmaların sayısının artması önemlidir. Bu alanda literatüre katkı sağlamayı amaçlayan bu makalenin konusu; önemli askeri ve idari hizmetlerde bulunan, ancak ömrünün son demlerinde yaşadığı siyasi sorunların ardından bir tür emeklilik ihsanı olarak Kudüs’te yaşama talebi kabul edilen Memlük emiri Emir Tâz tarafından inşa ettirilen, orta büyüklükte olduğunu düşündüğümüz Tâziyye Medresesi’dir. Mescid-i Aksa çevresinde kurulan ve sayıları elliyi aşan medreseden biri olan Tâziyye, XVI. asırda nüfusu ancak 5 bin civarında olan şehirdeki canlı ilim hayatının bir şahidi olarak Osmanlı devletinin hâkimiyeti döneminde de faaliyetine devam etmiştir. Osmanlı döneminde Arap coğrafyasında bulunan medreselerin yapısını ve işleyişini ele alan literatürde mevcut çalışmalar daha çok vakfiyesi bugüne gelen veya mansıp sahiplerinin ve talebelerinin izinin tabakât kitaplarından sürülebildiği yani hakkında malumata ulaşmanın nispeten kolay olduğu daha büyük ölçekli ve görünürlüğü olan yapılara odaklanmaktadır. Bu makalenin amacı ise, XVI. asırda Kudüs’ün ilmi kurumlarını ve yapısını anlayabilmek için büyük ve görünür bir örneğin değil, şehirde sayıca daha fazla olan ancak hakkında sınırlı miktarda malumata rastlanan orta ölçekli bir örneğin izini sürerek literatüre kazandırmaktır. Bunun için XVI. asırda farklı tarihlere ait Şer̒iyye sicilleri ve mühimme kayıtları ile literatürde mevcut çalışmalara müracaat edilecektir. Kudüs Şer̒iyye sicilleri Arapça olup defterlerin fiziki şartları ve yazı karakterleri sebebiyle okunması konusunda zorluklarla karşılaşıldığı için Türkçe literatürde, merkezine doğrudan bu yerel kaynakları alarak konuyu inceleyen çalışma sayısının az olması nedeniyle bu makale bu yönüyle de alana katkı sağlamayı amaçlamaktadır. Makale beş başlıktan oluşmaktadır. İlk başlıkta medresenin vâkıfı olan Memlük emiri Emir Tâz hakkında biyografik bilgilere, ikinci başlıkta medresenin mekânsal özelliklerine yer verilmiştir. Medresenin devamlılığı için en önemli unsur olan vakıf gelirlerinin ve bu işleyişte görevli kişilerin ele alındığı üçüncü başlıkta hem medresenin maddi desteğinin büyüklüğü incelenmiş hem işleyişte karşılaşılan bazı sorunlar ortaya konmuştur. Dördüncü başlıkta medresenin tedris faaliyetinin unsurlarına odaklanarak Kudüs medreselerinde mansıpların tevcihi, mansıp elde etmek için rekabet, medresenin tedris kapasitesi ve sunduğu imkânlar gibi konulara Tâziyye Medresesi özelinde yer verilmiştir. Beşinci başlıkta ise medresedeki diğer dini hizmetler incelenmiştir. Vakfiyesi bugüne ulaşmayan medresenin vakıf şartlarının detaylarına ve tarih boyunca değişime uğrayıp uğramadığı bilgisine ulaşmak henüz mümkün olmadığı gibi mevcut malumat tedrisin mahiyetine ve okutulan eserlerin hangileri olduğuna dair de detaylı bilgi elde etme imkânı sunmamaktadır. Kudüs ile alakalı medreseler ve daha büyük çerçevede ilmi hayat ile alakalı çalışmaların sayısı arttıkça literatürde bulunan bu boşlukların da doldurulması mümkün olacaktır.

Abluted capitalism: Ali Shariati's critique of capitalism in his reading of Islamic Economy
(Sage, 2015) Şengül, Serdar; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Islamic sociologist Ali Shariati is a leading figure of the reconstruction of religious thought in the Islamic world known especially for his anti-capitalist stance and leftist reading of Islamic history. In the philosophy of history that he developed, he classified religions as religions of tawheed (unicity of God) and religions of shirk (multiple gods). According to this new reading of history, the main struggle is not between religion and secularism but between religions of tawheed and of sheerk. The issue of the gaining and the distribution of the property is central to his classification. Shariati argued that followers of tawheed and of sheerk can be found in all religions including Islam. To support his argument Shariati explored how capitalistic understanding of Islam has been developed and legalised while anti-capitalist messages and orders of Islam were marginalised and illegalised just after the death of the Prophet Mohammed. He analysed the rivalry between his close companions over the content of a proper Islamic economic order and how this rivalry gave way to two contradicting understanding of Islam, marks of which can be seen today in the contemporary Muslim world. He coined the term abluted capitalism' to define the economic policies of Muslim sovereigns to make Islam compatible with capitalist economic principles.

Academic achievement and its relationships with psychological resilience and socio-demographic characteristics
(Routledge, 2018) Sakız, Halis; Aftab, Raiha; 02.04. Department of Educational Sciences / Eğitim Bilimleri Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This study focused on academic achievement among a sample of 810 students studying in vocational and nonvocational high schools in Turkey. It specifically investigated (a) the current levels of academic achievement and psychological resilience, (b) the relationships between levels of academic achievement and psychological resilience, (c) whether levels of academic achievement and psychological resilience will change based on sociodemographic variables, and (d) whether psychological resilience had a mediating effect on the relationship between sociodemographic variables and academic achievement. Quantitative data were collected through student records and questionnaires and analyzed via descriptive, correlational, and regression analysis and tests of difference (ANOVA). Findings indicated that academic achievement and psychological resilience were significantly related and they changed based on sociodemographic factors, namely income level and school type. In addition, psychological resilience had a significant mediating effect between academic achievement and sociodemographic factors. Findings indicate that the prevailing emphasis on enhancing academic achievement requires consideration of students’ psychological and sociodemographic conditions, while further research needs to investigate ways of carrying out this task. © 2018, © 2018 International School Psychology Association.

Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.

Activity of Metalaxyl-M plus mancozeb, Fosetyl-Al, and Phosphorous Acid against Phytophthora Crown and Root Rot of Apricot and Cherry Caused by Phytophthora palmivora
(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Türkölmez, Şahimerdan; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots. In both years, phosphorous acid at 200 and 215 g a.i./100 l, fosetyl-Al at 160 and 180 g a.i./100 l, and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Zerdali by 70.68-80.00% and crown rot severity on both Zerdali and Mahaleb, by 68.32-91.96 and 74.21-82.60%, respectively, compared with phosphorous acid at 187.5 g a.i./100 l, fosetyl-Al at 140 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l and control. Moreover, fosetyl-Al at 180 g a.i./100 l and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Mahaleb compared to fosetyl-Al at 140 and 160 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l, phosphorous acid treatments and control in 2012, providing the best control of the disease by 88.00-90.68%. Two/three phosphorous acid foliar applications at 200 g a.i./100 l suppressed symptom development when field applications were made on a curative basis in 2014 and 2015.

(Springer Science and Business Media Deutschland GmbH, 2023) Yiğit, Uğur; Türkkan, Muharrem; İlhan, Hasan; Şimşek, Tuncay; Güler, Ömer; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This study aimed to evaluate the antifungal activity of copper-boron (Cu-B) nanoalloys against a range of Phytophthora species, including P. capsici, P. citrophthora, P. palmivora, P. cinnamomi, P. nicotianae, P. cactorum, P. plurivora, P. inundata, and P. megasperma. The nanoalloys were synthesized via mechanical alloying under an argon atmosphere, resulting in the formation of nanocrystalline Cu-B nanoalloys with irregular morphology and particle sizes ranging from 50 to 240 nm. At a concentration of 250 µg mL−1, the Cu-B nanoalloys demonstrated complete inhibition of mycelial growth, sporangium production, and zoospore germination in all tested Phytophthora species. The EC50 values for mycelial growth ranged from 28.02 to 120.17 µg mL−1, while for sporangium production and zoospore germination, they were below 10 µg mL−1. Furthermore, the nanoalloys exhibited fungicidal activity against specific Phytophthora species, such as P. capsici, P. citrophthora, P. inundata, and P. megasperma, at concentrations of 100, 250, 250, and 250 µg mL−1, respectively. Notably, the Cu-B nanoalloys displayed significant protective and curative effects on tuber rot severity in P. nicotianae-inoculated potatoes, resulting in reductions of 94.13% and 92.61% compared to the control, respectively, at a concentration of 10 µg mL−1 (P < 0.05). These findings highlight the potential of Cu-B nanoalloys as a promising fungicide for the management of plant diseases caused by Phytophthora spp.

Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

Adaptions in subsistence strategy to environment changes across the Younger Dryas-Early Holocene boundary at Kortiktepe, Southeastern Turkey
(Sage Journals, 2022) Emra, Stephanie; Benz, Marion; Sıddıq, Abu Bakar; Özkaya, Vecihi; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The site of Körtiktepe in southeastern Turkey is one of few sites in the Upper Mesopotamia basin that attests continuous, permanent occupation across the boundary from end of the colder, drier Younger Dryas (YD) into the comparatively wetter and warmer Early Holocene (EH). This allows for the study of the degree of environmental change experienced on a local level over this boundary as well as for the study of the adaptations that the occupants of the site undertook in response to these changes. The mammal assemblage of Körtiktepe remains relatively stable across the YD – EH transition with the main contributors to diet being mouflon (Ovis orientalis) and red deer (Cervus elaphus) in approximately the same quantities, although the contribution of aurochs (Bos primigenius) increases in the EH. The most significant changes can be seen in the shift in avifauna remains, with a sharp increase of waterbirds during the EH. It is proposed that these shifts reflect changes in the local environment with an increase in woodland cover as well as expansion of local waterways, which is generally consistent with previously published archaeobotanical studies. In terms of species exploited, mortality profiles as well as size distribution of mammals, a great deal of continuity is observed. This suggests that over this particular period the local impact of the beginning of the Early Holocene was not overly dramatic, allowing for cultural continuity of previously established subsistence strategies.

Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation
(SPRINGER HEIDELBERG, 2019) Yildiz, Resit; 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
2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.

PurposeThis study aims to prevent mild steel (MS) against corrosion in 0.5 M HCl solution, 2-amino-4-methoxy-6-methyl-1,3,5-triazine was used. The effectiveness of the compound as a corrosion inhibitor was studied via electrochemical, surface and theoretical calculation techniques. Design/methodology/approachFor concentrations ranging from 0.5 to 10.0 mM, almost similar polarization resistances were obtained from electrochemical impedance spectroscopy (EIS) and linear polarization resistance tests. It also investigated inhibitive activity of 2-amino-4-methoxy-6-methyl-1,3,5-triazine on the steel surface using scanning electron and atomic force microscope instruments. Langmuir adsorption is the best matched isotherm for the adsorption of the inhibitor to the steel surface. FindingsEIS method was used to determine inhibition efficiency, which was determined to be 95.7% for 10.0 mM inhibitor containing acid solution. Density functional theory's predictions for quantum chemistry agreed well with the other experimental results. Originality/valueThe methods used in this study are effective and applicable; the used organic inhibitor is 2-amino-4-methoxy-6-methyl-1,3,5-triazine; and protective effectiveness is important, which is crucial for the task of MS corrosion prevention.

Mercury is known to be one of the most toxic heavy metals in the environment and is released into the water systems in significant quantities through natural events and industrial process activities. Many chemical materials are used as adsorbents in the removal of toxic metals from the environment and wastewaters. However, using microorganisms as bio-sorbents instead of chemical materials has become common recently due to their low cost, easy availability and presence in nature. In this study, Bacillus licheniformis in the soil isolated from the Tigris River was used as bio-sorbent. The mercury (Hg(II)) absorption behaviour of Bacillus licheniformis bacteria (BLB) was investigated using inductively coupled plasma mass spectrometry. The effects of equilibrium of adsorption time, temperature, adsorbent dosage and pH on the adsorption of Hg (II) onto BLB were determined. The maximum adsorption capacity of Hg (II) onto BLB was determined as 82.12 mg/g (T = 25 degrees C, pH 5, Co = 50 mg/L, m = 25 mg). The BLB was characterised using Fourier transform infrared spectroscopy analysis, thermal gravimetric analysis/differential thermal analysis, scanning electron microscopy analysis and energy-dispersive X-ray spectroscopy analysis. In addition, pseudo-first-order and pseudo-second-order kinetic models were applied. The equilibrium data for the adsorption of Hg(II) onto BLB were examined by the Langmuir and Freundlich isotherm models. The activation energy was calculated using the pseudo-second-order rate constant. These results suggested the BLB can be used as an efficient adsorbent for the removal of Hg(II) metal ions from wastewater. When the results of bio-sorption studies were examined, it was found that the bio-sorbent could be reused easily. The present study suggests that microorganism bio-sorbents are useful for the efficient removal of mercury from aqueous solutions.

Nano vaccines are assumed to upregulate the immune system as well as infection prevention. They are probably promising candidates for chronic autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, AIDS, and COVID-19 infectious. Based on this, we will describe the different working mechanisms of nanoparticles. In addition, applicable nano vaccines which have been approved for COVID-19 therapy Covid 19 are described. Antigen-carrying nanoparticles can affect the immune response and significantly enhance cell-T cytotoxic response. Nanoscale particles can improve vaccine efficiency because of their biomedical benefits. These properties include Small size, which allows better penetration into tumors and more half-life tumor cells. Current vaccines, however, are required to re-formulate almost because of gradual antigen modifications. More ever these vaccines do not protect against mutations and the low half-life of current vaccines due to limitations of current technologies. Nano vaccine formulation improvements have been required to induce a widespread and potent immune response. In this review, we provide an overview ofthe types and applications of nanoparticles in vaccines and their outstanding properties that made them alternatives for Covid-19 treatment. © 2023, Bentham Books imprint.

(Springer, 2023) Güzel, Tuncay; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background: In this study, we investigated whether there is a higher incidence of cardiac implantable electronic devices (CIED) procedures related complications in older (≥ 75 years) than in younger (< 75 years) patients. Methods: This retrospective cohort study enrolled patients who had undergone CIED procedures (de novo implantation, system upgrade, generator substitution, pocket revision or lead replacement) at two heart centers in Turkey between January 2011 and May 2023. The primary composite endpoint included clinically significant hematoma (CSH), pericardial effusion or tamponade, pneumothorax, and infection related to the device system. Secondary outcomes included each component of the composite end point. Results: The overall sample included 1923 patients (1419 < 75 years and 504 aged ≥ 75 years). There was no difference between the groups in terms of cumulative events defined as primary outcome (3.5% vs. 4.4%, p = 0.393). Infection related to device system was significantly higher in the ≥ 75 age group (1.8% vs. 3.4%, p = 0.034). There was no significant difference between the groups in terms of clinically significant hematoma and pneumothorax (0.7% vs. 0.4%, p = 0.451, 1.4% vs. 1.0%, p = 0.477, respectively). In multivariate model analysis, no association was found between age ≥ 75 years and infection related to the device system. Conclusion: Infection rates were relatively higher in the patient group aged ≥ 75 years. This patient group should be evaluated more carefully in terms of infection development before and after the procedure.

Air Quality Forecasting Using Machine Learning: Comparative Analysis and Ensemble Strategies for Enhanced Prediction
(Springer Int Publ Ag, 2025) Ozupak, Yildirim; Alpsalaz, Feyyaz; Aslan, Emrah; 08.01. Department of Computer Engineering / Bilgisayar Mühendisliği Bölümü; 08. Faculty of Engineering and Architecture / Mühendislik Mimarlık Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Air pollution poses a critical challenge to environmental sustainability, public health, and urban planning. Accurate air quality prediction is essential for devising effective management strategies and early warning systems. This study utilized a dataset comprising hourly measurements of pollutants such as PM2.5, NOx, CO, and benzene, sourced from five metal oxide sensors and a certified analyzer in a polluted urban area, totaling 9,357 records collected over one year (March 2004-February 2005) from the Kaggle Air Quality Data Set. A comprehensive comparison of ten machine learning regression models XGBoost, LightGBM, Random Forest, Gradient Boosting, CatBoost, Support Vector Regression (SVR) with Bayesian Optimization, Decision Tree, K-Nearest Neighbors (KNN), Elastic Net, and Bayesian Ridge was conducted. Model performance was enhanced through Bayesian optimization and randomized cross-validation, with stacking employed to leverage the strengths of base models. Experimental results showed that hyperparameter optimization and ensemble strategies significantly improved accuracy, with the SVR model optimized via Bayesian optimization achieving the highest performance: an R2 score of 99.94%, MAE of 0.0120, and MSE of 0.0005. These findings underscore the methodology's efficacy in precisely capturing the spatial and temporal dynamics of air pollution.

Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad; 16.02. Department of Seed Production / Tohumculuk Teknolojisi Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.

Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression
(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, Ahmet; 09.02. Department of Midwifery/ Ebelik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
In the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.
