Article Citation - WoS: 9Citation - Scopus: 12Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes(2017) Aktaş, Hüsnü; Baloch, Faheem ShehzadThe 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.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 ShehzadThe 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.

As result, heavy metal removal or remediation from hazardous sites has become mandatory. Bioremediation based on microorganisms is promising method to remediate heavy metal-contaminated areas due to its ecofriendly, cost-effective, and highly efficient characteristics. This study aimed to isolate, identify, and characterize rhizospheric bacteria able to resist, reduce, and detoxify heavy metals [chromium (Cr), nickel (Ni), and aluminum (Al)] from agricultural soil. Two isolates were chosen due to their high level of heavy metal resistance and could serve as potential in situ remediation agents at the site of isolation. On the basis of morphological, cultural, biochemical, and molecular characterization, these two isolates were identified as Pseudomonas aeruginosa (S1) and Bacillus cereus (S2). The results revealed a minimum inhibitory concentrations (MICs) of the three heavy metals studied, ranging from 1000 to 1400 mu g/mL for the two bacterial isolates. Atomic absorption spectroscopy analysis was used to evaluate the degrading potential. B. cereus was able to reduce Cr and Al more than P. aeruginosa (42% and 67.78% vs. 38.44% and 58.85, respectively). On the other hand, P. aeruginosa showed a higher capacity to degrade Ni than B. cereus (62.33% and 50.76%, respectively). The findings of the analysis revealed information regarding the use of these heavy metal-resistant bacterial isolates as potential bioremediation agents in contaminated environments. Microbial bioremediation offers sustainable alternatives to the traditional physical or chemical remediation technologies of agricultural land.Article Citation - WoS: 8Citation - Scopus: 9Prevalence of obesity in elementary schools in mardin, South-Eastern of Turkey: A preliminary study(2012) Battaloğlu İnanç, Betül; Şahin Say, Deniz; Oğuzöncül, Ayşe Ferdane; Bindak, Recep; Mungan, FerideAmaç: Bu araştırmada, Mardin ilindeki ilköğretim çağı çocukları arasında obezite sıklığı, obezite ile aile ve çevre faktörleri arasındaki ilişki değerlendirildi. Materyal ve Metot: Çalışmada Mardin il merkezindeki, üç ilköğretim okulunda 6-15 yaş grubundaki, 3460 çocuğun boy ve ağırlık ölçümleri yapıldı. Beslenme alışkanlıkları ve aile-çevre faktörlerine ait bilgiler anket yolu ile elde edildi. Her öğrenci için vücut kitle indeksi (BMI) hesaplandı. Dünya Sağlık Örgütü (WHO) tarafından çocuk ve adolesanlarda fazla kilolu olma ve obezitenin sınıflandırılmasında kullanılması önerilen ve 2007 yılında yayınlanan 5-19 yaş grubu çocuklar ve adolesanlar için büyüme referans değerleri baz alınarak hesaplandı. Söz konusu referans değerlerine göre vücut kitle indeksi (BMI)değeri 97. persentil üzerinde olan çocuklar obez; BMI değeri 85-97. persentil arasında olanlarda fazla kilolu olarak tanımlandı. Veriler bilgisayarda SPSS istatistik programı ile değerlendirildi. Analizler için ki-kare ve t-testleri kullanıldı. P<0.05 istatistiksel olarak anlamlı kabul edildi. Bulgular: Öğrencilerin % 48.2’si kız idi. Fazla ağırlığı (overweight) olan çocuk %15.78, obez olan çocuk oranı %10.57 idi. Cinsiyete göre obezite sıklığı kız çocuklar için %9.05 ve erkek çocuklar için %11.97 idi. Erkeklerde obezite sıklığı anlamlı derecede daha yüksekti (p<0.01). 13 -15 yaş grubundaki kızların BMI ortalamaları, aynı yaş grubundaki erkeklere göre anlamlı derecede yüksekti. Sosyoekonomik düzeyi yüksek olanlarda (p<0.01), düzensiz öğün yiyenlerde (p=0.05) , günde 2 saatten fazla TV seyredenlerde (p=0.03), 6 aydan az anne sütü alanlarda (p<0,05), annesi (p<0.05) veya babası (p<0.01) obez olanlarda obezite sıklığı anlamlı derecede daha yüksek bulundu. Sonuç: Obezite bir sağlık sorunu olarak dünya çapında artmaktadır. Çocukluk çağında obez olmak ve obez ebeveyn/(ebeveynlere) sahip olmak, erişkinlikte obez olmanın risk faktörlerinden ikisidir. Yetişkinlikte, obezitenin kalıcılığı, sorunun en ciddi yönüdür. Obezitede tedavi başarı oranı, ne yazık ki yüksek değildir. Bu nedenle, rutin çocukluk çağı büyüme değerlendirilmesi için, vücut kitle indeksinin eklenerek, risk altında olanların erken tespiti ile ilgili bir önleyici strateji en akılcı yol olarak görünmektedir.Article Citation - WoS: 5Citation - Scopus: 6Bronchiectasis in Türkiye: Data From a Multicenter Registry (Turkish Adult Bronchiectasis Database)(Galenos Publ House, 2024) Edis, Ebru Cakir; Cilli, Aykut; Kizilirmak, Deniz; Coskun, Ayson Sakar; Guler, Nurcan; Cicek, Sedat; Sayiner, AbdullahBackground: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry -based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in T & uuml;rkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in T & uuml;rkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non -cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 +/- 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation -related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in T & uuml;rkiye. The study results will provide important data that can guide the development of health policies in T & uuml;rkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.
