Article Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes(Turkish Journal of Agriculture and Forestry, 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 ÜniversitesiThe 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.Review Citation - WoS: 1Citation - Scopus: 1Anatolian Medicinal Plants as Potential Antiviral Agents: Bridging Traditional Knowledge and Modern Science in the Fight Against Covid-19 and Related Viral Infections(Tubitak Scientific & Technological Research Council Turkey, 2024) Jahan Sıddık, Israt; Jahan, Israt; Hoser, Ayse; Kaplan, Alevcan; Ozdemir, Oguzhan; Onay, Ahmet; Department of Health and Nursing Services / Sağlık ve Bakım Hizmetleri Bölümü; 21. Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiThe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was the cause of the coronavirus 2019 (COVID-19), commonly known as the coronavirus pandemic. Since December 2020, COVID-19 vaccines have been extensively administered in numerous countries. In addition to new antiviral medications, the treatment regimen encompasses symptom management. Despite sustained research efforts, the outbreak remains uncontrolled, with affected patients still lacking proper treatment. This review is a valuable asset for researchers and practitioners aiming to delve into the yet unexplored potential of Anatolian flora in the fight against COVID-19 and other viral infections. Numerous medicinal plants in Anatolia, such as thyme, sage, cannabis, oregano, licorice root, and Origanum sp., contain bioactive compounds with proven antiviral properties that have been used in the region for centuries. The rich legacy of traditional Anatolian medicine (TAM), has significantly influenced modern medicine; thus, the profusion of medicinal plants native to Anatolia holds promise for antiviral drug development, making this review essential for researchers and practitioners.Article Citation - WoS: 1Citation - Scopus: 1Evaluation of the Results of the Patients Who Underwent Plasmapheresis in the Pediatric Intensive Care Unit(Tubitak Scientific & Technological Research Council Turkey, 2024) Talay, Mehmet Nur; Orhan, Ozhan; Orhan, Özhan; Özbek, Mehmet Nuri; Ozbek, Mehmet Nuri; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground/aim: Therapeutic plasma exchange (TPE) is an extracorporeal treatment method that removes large molecular weight substances from plasma. In our study, we aimed to retrospectively examine the indications and procedural methods of the patients who had undergone TPE, and the complications that occurred during the procedure. Materials and methods: Forty-one patients who were monitored in thePICU of Gazi Ya & scedil;argil Training and Research Hospital and had indications for TPE between 2017 and 2021 were included in the study. Laboratory parameters were checked before and after the TPE procedure. In addition to these, patients' diagnosis, weight, type of procedure and type of device, where the procedure was performed, duration of the procedure, amount of blood and plasma processed, complications, number of procedures, and death during the procedure or independent of the procedure were evaluated. Results: The median age was 93.0 (14.0-167.0) months. Hemolytic uremic syndrome (HUS) was the most common TPE indication with nine patients. The most common complication related to TPE was fever (11 patients), while no complication was observed in 18 patients. When laboratory results were evaluated according to American Society for Apheresis (ASFA) categories, a significant improvement was observed in the values of platelet, AST, ALT, LDH, urea, and creatinine in ASFA1 after TPE. No significant improvement was observed in ASFA2 (p > 0.05). In ASFA3, a significant improvement was observed in INR, AST, ALT, LDH, total bilirubin, creatinine, pH, and lactate values after TPE (p < 0.05). Five patients died from ASFA1, one from ASFA2, and three patients from ASFA3. Conclusion: Since significant adjustments are observed in clinical and laboratory values in sepsis-MOF, which is in the ASFA3 category, we believe that it should be evaluated in the ASFA2 or ASFA1 category in the early treatment of these diseases. In addition, we think that MIS -C cases, which have not been in any category according to ASFA, should be included in the ASFA2 or ASFA3 category, considering our TPE results.Article Citation - WoS: 2Citation - Scopus: 1Investigation of Antibacterial and Antifungal Efficacy of Zinc and Silver Nanoparticles Synthesized From Nasturtium Officinale(Ankara Univ, Fac Agriculture, 2023) Ercan, LeylaNanoparticles are nano -sized materials that can be widely used in fields such as medicine, pharmacology, and industry. The use of natural and easily available materials in nanoparticle synthesis is preferable for economic reasons. Plants are extremely suitable for the synthesis of nanoparticles due to their wide availability and the large number of components they contain with various properties. For this purpose, silver nanoparticles and zinc nanoparticles (AgNPs and ZnNPs), two different nanoparticles were synthesized from an edible plant, watercress (Nasturtium officinale). Scanning electron microscopy, scanning electron microscopy -energy dispersive X-ray, UV-VIS spectroscopy, X-ray diffraction (XRD), and fourier transform infrared spectrophotometer (FTIR) analyses of these nanoparticles were performed. In addition, the antimicrobial effects of these synthesized nanoparticles were determined using the disk diffusion method. The nanoparticles obtained from Nasturtium officinale were effective on Gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa), Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes), and fungi (Candida albicans). In particular, AgNPs with broad-spectrum antimicrobial activity were obtained from the watercress. While ZnNPs showed inhibition effects of 49% on K. pneumoniae, 51% on S. aureus, and 62% on C. albicans, AgNPs showed inhibition effects of 93% on P. aeruginosa, 87% on S. aureus, 81% on E. coli, 80% on C. albicans, 72% on K. pneumoniae, and 56% on S. pyogenes. The results show that Nasturtium officinale can be used effectively in the production of new biotechnological products, particularly ones with antimicrobial properties.Article Citation - WoS: 1Citation - Scopus: 1On a New Characterization of Some Class Nonlinear Eigenvalue Problem(Hindawi Limited, 2019) Akin, L.; Akın, Lütfi; Department of Management / İşletme Bölümü; 04.

Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAs a starting material, 7-tert-butyldibenzo [b,e] [1,4] dioxine-2,3-dicarbonitrile was prepared by the reac- tion of 4-tert-butylcatechol with 4,5-dichlorophthalonitrile. Metallophthalocyanine complexes ( 4 { 7 ) were obtained by cyclotetramerization of 7-tert-butyldibenzo [b,e] [1,4] dioxine-2,3-dicarbonitrile. All compounds were characterized by elemental analysis and other spectroscopic methods (IR, UV/Vis, and 1 H NMR). Phthalocyanine compounds remained nonaggregated in tetrahydrofuran at the studied concentration ranges. Metallophthalocyanines ( 4 { 7 ) were tested for their antioxidant activities. The antioxidant activity processes included evaluation of radical-scavenging activity, chelat- ing activity, and reducing power. These compounds were compared to standard antioxidant ascorbic acid. The electronic data of the new compounds were obtained by computational calculations at the B3LYP/6-31G (d,p) level of theory.Article Volatile Compounds, Bioactive Properties and Chlorophylls Contents in Dried Spearmint (Mentha Spicata L.) as Affected by Different Drying Methods(Journal of Agricultural Sciences, 2023) Korkmaz, Aziz; Arslan, Erhan; Koşan, Meltem; 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 ÜniversitesiThis study presents a comparison of the quality characteristics of spearmint (Mentha spicata L.) dried by a photovoltaic thermal dryer (PVT), the shade dried spearmint (SDS), and an oven dried spearmint (ODS). The obtained samples were evaluated with respect to volatile compounds (VC), total phenolic content (TPC) and flavonoid content (TFC), antioxidant capacity (AC) and chlorophylls (Chl) contents. PDS had the highest amount of TPC, TFC and AC, while SDS and ODS did not differ significantly from each other in terms of these features. SDS exhibited the highest Chl a and Chl b contents, whereas ODS showed the lowest. The composition of VC in the dried spearmints was significantly affected by the drying methods used. The total amount of terpenoids, especially carvone, responsible for spearmint’s characteristic aroma in SDS was higher than those of the others, while the concentrations of most VC were lowest in ODS. According to the results, the PVT can be recommended for drying spearmint.
